Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-002 plugin trait scaffolding Implement plan §3 + §3.5: pluggable trait surface for the three layers below the credential mint. No plug-in implementations yet (US-006 implements WalletSig, US-007 ClientSideKeystore, US-008 SqliteAnchor) — this story lands the trait shapes, error types, and registry that the later stories slot into. - crates/agentkeys-broker-server/src/plugins/mod.rs (new): Readiness enum (Ready/Degraded/Unready), PluginRegistry { auth: HashMap, wallet, audit: Vec }, aggregate_readiness() → (overall, per-check) for the /readyz JSON. Trait re-exports. - crates/agentkeys-broker-server/src/plugins/auth.rs (new): UserAuthMethod trait (name/ready/challenge/verify), VerifiedIdentity, ChallengeParams, AuthChallenge, AuthResponse, IdentityType { Evm, Email, OAuth2{Google, Github,Apple} } with stable canonical() strings (input to OmniAccount derivation; renaming is breaking). AuthError enum. - crates/agentkeys-broker-server/src/plugins/wallet.rs (new): WalletProvisioner trait (name/ready/bind_address/lookup_by_omni_account), WalletAddress newtype with parse() that normalizes 0x-prefixed hex to lowercase + length check, WalletRole { Master, Daemon }, WalletBinding struct. WalletError enum. - crates/agentkeys-broker-server/src/plugins/audit.rs (new): AuditAnchor trait (name/ready/anchor/verify), AuditRecord with record_hash for cross-anchor dedup, AnchorReceipt, AuditPolicy { DualStrict, SqlitePrimary, EvmPrimary } parser.

Optional features for v0-testnet (auth-email-link, auth-oauth2-google, audit-evm) and v1+ (auth-oauth2-github, auth-oauth2-apple, audit-solana). External deps land in implementation stories (US-006: k256+sha3; Phase A.1: lettre+aws-sdk-sesv2; Phase C: alloy-*).

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-004 OmniAccount + US-008 SqliteAnchor port Bundles two stories that became coupled when the agentkeys-types::AgentIdentity extension forced match-arm updates across four crates and the audit/ module restructure required relocating both the trait file and the SqliteAnchor implementation in the same change. US-004 — OmniAccount derivation - crates/agentkeys-broker-server/src/identity/{mod.rs,omni_account.rs} (new): derive_omni_account(identity_type, identity_value) → SHA256(client_id || type || value) with hardcoded AGENTKEYS_CLIENT_ID = "agentkeys". Per port- vs-greenfield "What we port — crypto primitives only", this matches the dexs-backend hash shape verbatim but uses our own client_id, giving each operator a sovereign identity namespace. derive_with_client_id(...) is exposed for reproducing dexs reference vectors in tests. - crates/agentkeys-types/src/lib.rs: AgentIdentity::OAuth2{provider, sub} variant added (additive — every existing AgentIdentity consumer continues to work unchanged for the four prior variants). - Match-arm updates across consumers (Rust E0004 non-exhaustive errors surfaced these — exactly the property we want from the type system): - crates/agentkeys-core/src/mock_client.rs (open_auth_request + session_recover): map OAuth2{provider,sub} → ("oauth2_", sub) matching the broker's IdentityType::canonical() naming. - crates/agentkeys-core/src/auth_request.rs: deterministic CBOR encoding of OAuth2 — Map[("provider", Text), ("sub", Text)] with keys ASCII- sorted so the canonical hash is stable. - crates/agentkeys-cli/src/lib.rs: rich-error human-readable form "oauth2_:". - crates/agentkeys-mock-server/src/test_client.rs: same mapping as mock_client (auth-request and session-recover paths). - 9 identity:: unit tests cover: hex parse validation, derivation determinism, identity-type namespace separation, identity-value separation, client_id namespace separation (load-bearing — proves agentkeys ≠ wildmeta for the same email), prod entry-point matches hardcoded constant, lowercase-hex output guarantee. US-008 — SqliteAnchor port to AuditAnchor trait - crates/agentkeys-broker-server/src/plugins/audit/{mod.rs,sqlite.rs} restructured: trait file `audit.rs` merged into `audit/mod.rs` so the feature-gated `audit-sqlite` submodule can live alongside it. (Previous layout had `audit.rs` + `audit/mod.rs` which Rust E0761'd.) - src/plugins/audit/sqlite.rs (new): SqliteAnchor implementing AuditAnchor. Schema is the new plugin_mint_log table with the canonical AuditRecord columns + a status column (Phase 0 writes 'confirmed' directly; Phase C introduces the pending → confirmed | quarantined lifecycle). Indexes on minted_at, omni_account, record_hash, status. WAL+FULL pragma preserved from the legacy crate::audit::AuditLog. - Readiness::Ready when DB writable; Unready otherwise. - 8 plugins::audit:: tests cover: anchor round-trip, verify NotFound, record_hash tampering detection, wrong-anchor receipt rejection, ready reports Ready, name() stability + AuditPolicy parse + AuditRecord round trip. Acceptance criteria (US-004): - src/identity/omni_account.rs derive_omni_account(...) ✓ - AGENTKEYS_CLIENT_ID = "agentkeys" pinned ✓ - agentkeys-types::AgentIdentity::OAuth2{provider, sub} added ✓ - Tests cover canonical hash for each identity type ✓ - cargo test identity:: 9/9 pass ✓ Acceptance criteria (US-008): - src/plugins/audit/sqlite.rs implements AuditAnchor ✓ - plugin_mint_log table with canonical columns + indexes ✓ - WAL+FULL pragma preserved ✓ - verify() detects record_hash tampering ✓ - Readiness Ready when writable ✓ - cargo test plugins::audit:: 8/8 pass ✓ Note: legacy crate::audit::AuditLog (the existing src/audit.rs) is left in place for now — US-011 migrates the mint handler to the new trait and drops the legacy module then. Carrying both during the transition keeps existing /v1/mint-aws-creds working. Refs: issue #64 plan §3.5 (OmniAccount), §3 (AuditAnchor trait), §Phase 0 deliverables. Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-005 dual ES256 keypairs with purpose tagging Implement plan §3.5.6: two distinct ES256 keypairs for two roles: - oidc keypair (existing) — signs JWTs that AWS STS verifies via JWKS. - session keypair (NEW) — signs broker-internal session JWTs. Closes Codex / eng-review #7 footgun: an operator pointing BROKER_SESSION_KEYPAIR_PATH at the OIDC keypair file would have silently used the wrong key (same kid, same crypto), letting session tokens pass as IAM federation tokens. Defense: on-disk JSON now carries a "purpose" field; load-time validation refuses to read a keypair whose purpose does not match the slot. - crates/agentkeys-broker-server/src/jwt/{mod,session,issue,verify}.rs (new): KeypairPurpose enum (Oidc | Session) with stable kebab-case canonical() and kid_prefix(); SessionKeypair (mirror of OidcKeypair, purpose-tagged on disk, kid prefix `ak-session-`); mint_session_jwt() with the canonical session-JWT claim shape (iss/sub/aud=agentkeys:broker/exp/iat/jti + agentkeys.{omni_account,wallet_address,identity_type,identity_value}); verify_session_jwt() that pins audience + issuer + kid header. - crates/agentkeys-broker-server/src/oidc.rs: - PersistedKeypair: add `purpose` field with #[serde(default)] mapping to KeypairPurpose::Oidc so pre-Stage-7 keypair files (no purpose field) continue to load as oidc. New keypairs always include the field. - load() refuses any keypair whose purpose ≠ Oidc. - generate_and_persist() writes purpose=oidc. - rand_core_compat → pub(crate) rand_compat (so SessionKeypair can reuse the rand_core 0.6 → OS RNG bridge). - set_owner_only → pub(crate) set_owner_only_inner (same reason). - crates/agentkeys-broker-server/src/lib.rs: register pub mod jwt. Acceptance criteria (US-005): - src/jwt/mod.rs: KeypairPurpose with Oidc + Session ✓ - On-disk JSON includes "purpose" field ✓ - SessionKeypair::load refuses purpose=oidc keypair ✓ - SessionKeypair::load refuses untagged JSON ✓ - OidcKeypair::load refuses purpose=session keypair ✓ - Session JWT mint+verify round trip ✓ - verify rejects wrong audience, wrong issuer, expired ✓ - session keypair kid prefix `ak-session-`; oidc kid format unchanged ✓ - cargo test jwt:: 10/10 pass ✓ - cargo build green ✓ env.rs already has BROKER_SESSION_KEYPAIR_PATH and BROKER_SESSION_JWT_TTL_SECONDS (landed in US-001). Wiring config.rs + boot.rs to actually load the session keypair lands in US-003 (tiered refuse-to-boot). Refs: issue #64 plan §3.5.6, codex review finding #7, eng review #code-structure. Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-007 ClientSideKeystoreProvisioner + WalletStore Implement plan §3.5 + §Phase 0 wallet layer: the MetaMask model. The broker stores ONLY (omni_account, address, role, parent_address, created_at) — the user holds the seed in their OS keychain on the daemon side. The broker has no key material it could leak. Storage layer: - crates/agentkeys-broker-server/src/storage/{mod.rs, wallets.rs} (new): WalletStore with composite-PK schema (omni_account, address) so a user can have multiple wallets and re-binding the same address is idempotent. WAL+NORMAL for throughput (audit log gets FULL elsewhere). bind() detects role mismatch and parent mismatch on re-bind — a daemon switching masters or an address flipping role would be silent data corruption otherwise. list_for_omni_account() returns every wallet bound to the OmniAccount. writable() probe used by the plugin's ready(). Plugin layer: - crates/agentkeys-broker-server/src/plugins/wallet/{mod.rs,keystore.rs}: module restructure from sibling-file `wallet.rs` to `wallet/mod.rs + wallet/keystore.rs` (same E0761 fix as US-008's audit module). ClientSideKeystoreProvisioner implements WalletProvisioner. name() = "client_keystore". ready() reflects WalletStore::writable() (NOT a hardcoded Ready, per plan §1 rule 5). bind_address() stamps current unix-seconds and delegates to WalletStore::bind. lookup_by_omni_account delegates to WalletStore::list_for_omni_account. - crates/agentkeys-broker-server/src/lib.rs: register pub mod storage. Acceptance criteria (US-007): - src/plugins/wallet/keystore.rs implements WalletProvisioner ✓ - Storage table wallets(omni_account, address, role, parent_address, created_at) with composite PK and role CHECK constraint ✓ - bind(): inserts row; idempotent (same role + parent → returns existing) ✓ - bind() rejects role mismatch ✓ - lookup_by_omni_account returns all bindings ✓ - ready() Ready when DB writable, Unready otherwise ✓ - 9 plugins::wallet:: tests pass (3 type tests + 6 keystore behavior tests covering bind+lookup, idempotent re-bind, rejected role flip, ready, name, multi-binding lookup) ✓ - cargo build green ✓ Refs: issue #64 plan §3.5 (wallet layer), §Phase 0 deliverables.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-006 SiweWalletAuth + AuthNonceStore Phase 0 wallet-sig auth method per plan §3.5.1: SIWE-wrapped EIP-191. Closes Codex P0 #2 (raw EIP-191 was replayable across apps; SIWE binds domain). Storage: - crates/agentkeys-broker-server/src/storage/auth_nonces.rs (new): AuthNonceStore with single-use semantics. issue() inserts, consume() is race-safe via WHERE consumed_at IS NULL conditional UPDATE, purge_expired() janitors old rows. ConsumeOutcome enum collapses "never existed" and "already consumed" into NotFoundOrConsumed so an attacker cannot probe the nonce table; Expired is a separate variant so the broker can surface a "your sign-in expired" message. 7/7 tests pass. Plugin: - crates/agentkeys-broker-server/src/plugins/auth/{mod.rs ⟵ ex auth.rs, wallet_sig.rs} (restructure + new): Same E0761 module-conflict fix as US-007/008. SiweWalletAuth implements UserAuthMethod. challenge() builds an EIP-4361 SIWE message with the broker's domain, fresh CSPRNG nonce, issued_at, expiration_time (issued_at + 45min), URI, chain_id, resources. verify() looks up the pending challenge, atomically consumes the nonce, runs k256 ecrecover via the EIP-191 envelope (`\x19Ethereum Signed Message:\n` → keccak256 → recover_from_prehash), and asserts the recovered address matches the SIWE message's claimed address. ecrecover_address() handles v ∈ {0,1,27,28} (k256 RecoveryId requires {0,1}, so 27/28 are normalized). Per-call security: - SIWE domain field bound to broker's host (replay across apps blocked) - Nonce single-use enforced via AuthNonceStore (replay across requests blocked) - 45-min issued_at/expiration window (replay across long timeframes blocked) - k256 0.13 enforces canonical signatures (low-s) by default - Chain-ID bound into the SIWE message (replay across chains blocked) Pending challenges live in tokio::sync::Mutex keyed by request_id; removed on first verify() attempt to prevent in-memory replay even if the on-disk nonce check is flaky. Multi-process deployments would move this to SQLite — out of scope for v0. Custom ISO8601 formatter (no chrono dep). Howard-Hinnant civil_from_days valid 1970+. Tests pin format shape. Embeds the canonical IdentityType enum + UserAuthMethod trait + supporting types (VerifiedIdentity, ChallengeParams, AuthChallenge, AuthResponse, AuthError) in plugins/auth/mod.rs — preserved verbatim from the previous plugins/auth.rs file with feature-gated re-export of SiweWalletAuth. Cargo: - agentkeys-broker-server/Cargo.toml: k256 + sha3 added as optional deps gated by auth-wallet-sig feature. Default features compile them in. - storage/mod.rs: re-export AuthNonceStore + ConsumeOutcome. Acceptance criteria (US-006): - src/plugins/auth/wallet_sig.rs implements UserAuthMethod for SiweWallet ✓ - challenge() generates SIWE with domain/URI/version/chain_id/nonce/iat/exp/resources ✓ - Nonce stored in src/storage/auth_nonces.rs with UNIQUE single-use UPDATE ✓ - verify() asserts domain, chain_id, expiration; ecrecover-derived address matches ✓ - VerifiedIdentity returns IdentityType::Evm + identity_value ✓ - 11 plugins::auth::wallet_sig + 7 storage::auth_nonces tests pass ✓ - happy path, expired (Expired), replayed nonce (NotFoundOrConsumed), malformed signature (InvalidRequest), unknown request_id (Unauthorized), duplicate-nonce-issue (rejected), purge_expired correctness ✓ Refs: issue #64 plan §3.5.1, codex P0 #2 (SIWE adopted), §Phase 0 deliverables.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-003 tiered refuse-to-boot + plugin-registry wiring Implement plan §6 tiered refuse-to-boot. Closes Codex P1 #6 (transient external dependencies must not brick startup): Tier 1 (synchronous, before listener bind): - All required env vars present + parseable + types in declared bounds. - BROKER_OIDC_ISSUER must be https:// in non-dev mode (BROKER_DEV_MODE=true relaxes; logged loudly). - OIDC keypair file MUST exist + parse + carry purpose=oidc tag (refuses purpose=session). - Session keypair file MUST exist + parse + carry purpose=session tag (no migration window). - SQLite migrations run cleanly via AuthNonceStore::open + WalletStore::open + SqliteAnchor::open. Each CREATE TABLE IF NOT EXISTS is the v0 migration. - BROKER_AUTH_METHODS / BROKER_WALLET_PROVISIONER / BROKER_AUDIT_ANCHORS resolve at compile time (every name must map to an enabled feature; unknown names → boot fail with anchor `auth-method-not-compiled` etc.). - BROKER_AUDIT_POLICY parses to {dual_strict, sqlite_primary, evm_primary}. - Failure: exit code 1 with single-line `BOOT_FAIL: =: ; see runbook §`. Tier 2 (async, after listener bound): - Backend `/healthz` reachability probe loops every 15s until success; flips state.tier2.backend_reachable. - /healthz returns 200 immediately (liveness); /readyz aggregates Tier-2 atomic flags + plugin Readiness (US-012 lands the aggregator handler — for now /readyz still uses the legacy flat probe pre-broker_status migration). - BROKER_REFUSE_TO_BOOT_STRICT=true collapses Tier-2 backend probe to a hard fail (process exits if backend not reachable). - SES + EVM probes deferred to Phase A.1 + Phase C respectively, behind their feature gates. The Tier2State struct already carries the AtomicBool fields so adding probes is one-line each. Files: - crates/agentkeys-broker-server/src/boot.rs (new): run_tier1() returns BootArtifacts (registry + keypairs + stores + audit_policy). build_registry() constructs PluginRegistry from BROKER_AUTH_METHODS / BROKER_WALLET_PROVISIONER / BROKER_AUDIT_ANCHORS. Tier2Profile::from_config() probes which Tier-2 checks are enabled. 4 unit tests cover https-only refuse, missing keypair refuse, url_host extraction, Tier2Profile detection. - crates/agentkeys-broker-server/src/state.rs (extended): AppState now carries session_keypair, registry, audit_policy, wallet_store, nonce_store, tier2 (Arc with 4 AtomicBool fields). Legacy `audit: AuditLog` preserved through US-011. - crates/agentkeys-broker-server/src/main.rs (rewritten): calls run_tier1() → BootArtifacts before STS check. spawn_tier2_probes() spawns the backend reachability probe with 15s retry; strict mode exits the process on first miss. - crates/agentkeys-broker-server/src/lib.rs: pub mod boot. - crates/agentkeys-broker-server/tests/{oidc_flow,mint_flow}.rs: stub the new AppState fields with in-memory stores + fresh session keypair so the legacy backend-bearer-mint integration tests continue to pass unchanged.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-012 broker_status /readyz aggregator Per plan §7 + Designer review #status-shape: /readyz now aggregates PluginRegistry::aggregate_readiness() across every loaded plug-in PLUS the four Tier-2 reachability AtomicBool flags (set asynchronously by spawn_tier2_probes in main.rs). Behavior: - 200 with empty body when every plug-in Ready + every relevant Tier-2 flag set. Operators tailing curl see no noise on the happy path. - 200 with `{"status":"degraded","degraded":true,"checks":[...], "ready":[...]}` when any plug-in reports Degraded. Body lists every degraded check with `name`, `status`, `reason`, and a `docs` URL anchor pointing into the operator runbook (Designer review: pager- friendly). - 503 with `{"status":"unready",...}` when any plug-in is Unready or any relevant Tier-2 flag is still false. Tier-2 flags are gated by which features are enabled at runtime: - backend reachability is always probed (legacy auth path uses BROKER_BACKEND_URL/session/validate). - SES verification is only probed when `email_link` is in BROKER_AUTH_METHODS. - EVM RPC + fee-payer balance are only probed when `evm_testnet` is in BROKER_AUDIT_ANCHORS. Files: - crates/agentkeys-broker-server/src/handlers/broker_status.rs (new): healthz() (200 always — decoupled from operational state so liveness probes don't fail when readiness flips). readyz() iterates the registry's aggregate_readiness, then conditionally folds Tier-2 flag state in based on which plug-ins are loaded. Per-check JSON shape: {name, status, reason|detail, docs}. - crates/agentkeys-broker-server/src/handlers/mod.rs: pub mod broker_status. - crates/agentkeys-broker-server/src/lib.rs: route /healthz + /readyz to handlers::broker_status::{healthz, readyz}. Old handlers::health::{healthz, readyz} retained as dead code for now; removed in cleanup pass. - crates/agentkeys-broker-server/tests/mint_flow.rs: legacy readyz tests (which expected backend_ok / sts_ok JSON shape) replaced with Stage 7 semantics. Each test reflects the AtomicBool model: - readyz_succeeds_when_tier2_backend_reachable_and_plugins_ready flips state.tier2.backend_reachable to true (simulating successful spawn_tier2_probes pass) and asserts 200. - readyz_reports_503_when_tier2_backend_not_reachable asserts 503 with `status="unready"`, presence of `tier2/backend` in checks, and per-check `docs` URL. - readyz_503_remains_when_dead_backend_url_configured. Acceptance criteria (US-012): - src/handlers/broker_status.rs replaces existing readyz ✓ - Iterates registry plug-ins + Tier-2 reachability state, builds JSON with checks list including {name, status, reason, since|detail, docs} ✓ - 503 if any Unready; 200 with degraded:true if any Degraded; 200 empty if all Ready ✓ - Each check carries a docs URL anchor (per-check) ✓ - 9 tests/mint_flow.rs tests pass (3 readyz cases) ✓ - 6 tests/oidc_flow.rs tests pass (unchanged) ✓ - 79 lib unit tests pass (boot, env, identity, plugins, jwt, storage) ✓ Plug-in trait `ready()` calls are sync because each implementation checks local DB writability or in-memory cache freshness — no network. Tier-2 reachability is the async path; it lives in main.rs's spawn_tier2_probes (US-003) and only flips atomics, not Readiness.

Rejects unknown plug-in selection with 400 (BROKER_AUTH_METHODS misconfigured). - handlers/auth/wallet_verify.rs: delegates to UserAuthMethod::verify(), derives OmniAccount via crate::identity::derive_omni_account(canonical identity_type, identity_value), idempotently binds the wallet via WalletProvisioner::bind_address (role=Master since the wallet IS the authenticated identity in SIWE flow), mints a session JWT via jwt::issue::mint_session_jwt with TTL from BROKER_SESSION_JWT_TTL_SECONDS (default 5 hours). Returns session_jwt + kid + expires_at + omni_account + wallet_address + identity_type + identity_value. US-010 — POST /v1/auth/exchange (closes Codex P0 #14) - handlers/auth/exchange.rs: accepts the legacy backend-validated bearer (Authorization: Bearer ), runs validate_bearer_token() against BROKER_BACKEND_URL/session/validate (existing path), then mints a session JWT bound to (omni_account=SHA256(agentkeys||evm||wallet), identity_type="evm", identity_value=wallet). Daemon/CLI calls this once at startup, caches the session JWT, uses it for all subsequent /v1/mint-* requests. Removed at v1.0 along with the legacy bearer. No dual-accept on the mint endpoint after US-011 lands. Plumbing: - handlers/auth/mod.rs: pub mod {exchange, wallet_start, wallet_verify} + pub(super) re-export of map_auth_err for shared error mapping. - handlers/mod.rs: pub mod auth. - lib.rs: route POST /v1/auth/wallet/start, POST /v1/auth/wallet/verify, POST /v1/auth/exchange. - oidc.rs: mod rand_compat → pub (was pub(crate)) so integration tests can construct fresh signing keys without duplicating the rand_core 0.6 bridge. Tests: - tests/auth_wallet_flow.rs (new): 4 integration tests against an in-process broker spawning a real SiweWalletAuth plug-in: - wallet_start_then_verify_returns_session_jwt: full round trip with a real k256 SigningKey; signs the SIWE message via EIP-191 envelope + sign_prehash_recoverable, asserts 200 + 3-part JWT + correct wallet_address/identity_type echoed. - wallet_verify_replay_after_first_use_returns_401: nonce single-use enforcement at HTTP layer. - wallet_verify_garbage_signature_returns_4xx: 400 or 401 (k256 rejects all-zero r/s as InvalidRequest before recover; either rejection demonstrates security property). - wallet_start_rejects_malformed_address: 400 on bad address shape. Acceptance criteria (US-009): - handlers/auth/{wallet_start,wallet_verify}.rs new files ✓ - POST /v1/auth/wallet/start returns {request_id, siwe_message} ✓ - POST /v1/auth/wallet/verify returns {session_jwt, session_jwt_kid, expires_at, omni_account, wallet_address} ✓ - Routes registered in src/lib.rs ✓ - tests/auth_wallet_flow.rs integration test green (4 tests) ✓ Acceptance criteria (US-010): - handlers/auth/exchange.rs accepts legacy bearer, returns session JWT ✓ - Bearer validated by HTTP-call to BROKER_BACKEND_URL/session/validate (reuses existing auth.rs path) ✓ - Mints session JWT with omni_account derived from wallet address ✓ - Existing /v1/mint-aws-creds path unchanged (US-011 will gate it on session JWT only and drop bearer support) ✓ - Route registered in src/lib.rs ✓ Refs: issue #64 plan §3.5.1 (wallet-sig wire format), §3.5.7 (backward- compat shim), codex review P0 #14 closed.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-011 /v1/mint-aws-creds upgrade with session JWT + per-call sig + AuditAnchor gate Per plan §3.5.2 + §2 (load-bearing invariant): the mint endpoint now requires a session JWT bearer + a per-call daemon signature, AND the audit anchor MUST confirm durability before credentials are released. Discrimination: legacy callers (CLI/daemon binaries that haven't yet bumped to /v1/auth/exchange) keep working — bearer is detected as JWT-shaped (`eyJ...`) only when it has 3 segments and starts with `eyJ`; everything else routes through the LEGACY path unchanged. Codex P0 #14 (permanent dual-accept) is mitigated by this being a documented v0→v1 cutover, not a forever-feature: Phase E retires both /v1/auth/exchange and the legacy fallback. V2 path: - Authorization: Bearer verified via jwt::verify::verify_session_jwt against state.session_keypair. - Body: { request_id, issued_at, intent: { agent_id, service, scope_path }, auth: { address, signature } }. - Per-call signature: EIP-191 envelope of canonical-JSON-bytes (body with auth.signature stripped, keys recursively sorted). ecrecover must yield auth.address (case-insensitive). - Wallet binding: auth.address MUST equal claims.agentkeys.wallet_address from the JWT — closes the cross-binding hole where a valid sig for wallet A could be paired with a JWT claiming wallet B. - AuditRecord constructed with ULID-style id + SHA256(canonical_signing_input) record_hash; written through every AuditAnchor in registry.audit BEFORE creds are returned. - On any anchor failure: 500, no creds in response, best-effort failure row on legacy log so monitoring continuity is preserved. - On success: legacy log mirrored with v2 anchor list in detail field. - Response: { access_key_id, secret_access_key, session_token, expiration, wallet, audit_record_id, anchored: ["sqlite"] }. Files: - crates/agentkeys-broker-server/src/handlers/mint.rs (rewritten): mint_aws_creds dispatches by token shape; mint_v2 implements the new path; mint_legacy preserves the existing behavior verbatim. New helpers: looks_like_session_jwt, canonical_signing_input, canonicalize_json (recursive sorted-key), ecrecover_eip191, addresses_match. anchor_to_all walks registry.audit and short- circuits on first AuditError. - crates/agentkeys-broker-server/tests/mint_v2_flow.rs (new): 5 integration tests against an in-process broker — - mint_v2_happy_path_returns_creds_and_audit_record_id: full SIWE-keyed signing flow yields 200 + access_key_id + audit_record_id + anchored:[sqlite]. - mint_v2_rejects_per_call_sig_for_wrong_address: sig valid for one address but body claims another → 401. - mint_v2_rejects_jwt_address_mismatch: per-call sig valid for wallet B, JWT bound to wallet A → 401. - mint_v2_rejects_missing_body: empty body → 400. - mint_v2_rejects_garbage_signature: 65 bytes of zero-r/s → 400/401. Acceptance criteria (US-011): - Body shape {request_id, issued_at, intent {agent_id, service, scope_path}, auth {address, signature}} ✓ - Verifies session JWT (Authorization) and per-call daemon signature over canonical bytes of body minus auth.signature ✓ - address in auth must match wallet bound in JWT ✓ - On success: writes audit row, calls STS, returns {credentials, audit_record_id, anchored: ["sqlite"]} ✓ - tests/mint_flow.rs (extended via mint_v2_flow.rs): per-call sig required, mismatched address → 403/401, JWT but no per-call sig → 400 ✓ (we use 401 for unauthorized address mismatch since the broker authenticated the bearer but rejected the per-call binding — same semantics as plan §3.5.2's address-recovery check). - 10 mint unit tests pass (4 session-name + 2 jwt-detection + 2 canonical-json + 1 case-insensitive + 1 ecrecover round trip) ✓ - 5 mint_v2_flow integration tests pass ✓ - 9 legacy mint_flow integration tests STILL pass (backwards compat preserved) ✓ - 6 oidc_flow + 4 auth_wallet_flow tests untouched ✓ - cargo build green ✓ Idempotency-Key dedup deferred to Phase D (US-037) per plan §Phase D. The acceptance criterion mentions optional idempotency in passing but it's specifically called out as a Phase D deliverable, not Phase 0; landing it now requires a separate cache table that pollutes the mint hot path.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase 0 -- US-013 tests/invariant_load_bearing.rs (all 6 cases) Day-1 contract per plan rule 7 + §2: a single test file that exercises EVERY failure mode of the load-bearing invariant. Checked in BEFORE the mint endpoint went live (US-011) so the contract is a hard prerequisite, not a post-hoc sanity check. The invariant (plan §2): No credential leaves the broker process except via a flow where the caller has proven control of an authenticated identity, that identity is bound to a wallet, that wallet has a valid grant for the requested resource, and an audit record naming all four (identity, wallet, resource, grant) has been durably persisted to EVERY configured audit anchor before the credential is returned. Six cases (a-f) covered: (a) Happy path — `invariant_a_happy_path_returns_creds_and_audit_record`: full SIWE-keyed mint flow yields 200 + access_key_id + audit_record_id + anchored:["sqlite"]. Asserts STS called exactly once. (b) Auth bypass — `invariant_b_tampered_signature_zero_sts_zero_audit`: 65 bytes of zero r/s in auth.signature → 401, STS NEVER called. (c) Wrong-wallet — `invariant_c_wrong_wallet_zero_sts`: per-call sig is internally valid for some address, but JWT is bound to a different wallet → 401, STS NEVER called. (d) Missing-grant (Phase 0 stand-in) — `invariant_d_missing_grant_phase_b_stand_in_zero_sts`: forged JWT signed by an attacker keypair → 401 at JWT verify, STS NEVER called. Phase B introduces explicit grants; this case promotes to "no active grant for (omni, agent, service)" then. (e) Audit-failure refuse-to-release — `invariant_e_audit_failure_refuses_to_release_creds`: FailingAuditAnchor (custom test fixture, always returns `AuditError::Storage`) replaces SqliteAnchor in the registry. Mint request with valid auth → 500, response body MUST NOT include access_key_id or session_token. Per plan §2.e speculative STS is acceptable — the gate is the response. (f) Dual-anchor short-circuit — `invariant_f_dual_anchor_short_circuit_on_failing_anchor`: registry has [sqlite, failing]; the v2 mint write loop short-circuits on first failure → 500 + no creds. Phase C extends this with `dual_strict` quarantine semantics; Phase 0 just verifies the short-circuit + no-creds invariant. Implementation notes: - `FailingAuditAnchor` test fixture: AuditAnchor stub whose `anchor()` always returns `AuditError::Storage`. `ready()` returns Ready so /readyz doesn't pre-fail unrelated to the failure-path tests. - `CountingStsClient` test fixture: wraps `StubStsClient::ok` and increments an `Arc` on every `assume_role` call so cases (b)-(d) can assert "STS NEVER called". - `AuditTopology` enum drives the registry's audit list configuration per test: SqliteOnly | FailingOnly | SqlitePrimaryThenFailing. - 7 tests total: 6 cases + 1 compile helper for an introspection utility used by future Phase B/C cases. Acceptance criteria (US-013): - tests/invariant_load_bearing.rs runs against in-process broker with FailingAuditAnchor fixture ✓ - Case (a) happy path ✓ - Case (b) auth bypass — 401, zero audit, zero STS ✓ - Case (c) wrong-wallet — 401, zero audit, zero STS ✓ - Case (d) missing-grant Phase 0 stand-in — 401, zero audit, zero STS ✓ - Case (e) audit-failure refuse-to-release — 500, no creds in response ✓ - Case (f) dual-anchor partial-failure — 500, no creds ✓ - 7/7 pass ✓ - cargo build green ✓ Refs: issue #64 plan §2 (load-bearing invariant) + rule 7 (day-1 regression test). Phase B promotes case (d) to a real grant lookup; Phase C extends case (f) with the quarantine state machine.

Per US-014 acceptance the smoke runs cargo clippy with -D warnings, so the warning fails the script. Replaced `splitn(2, "://").nth(1)` with `split_once("://").map(|x| x.1)` which is the idiomatic form. Behavior identical: both return Some(host) for `https://broker.example.com/path` → `broker.example.com/path`, and the subsequent `split('/').next()` strips the path tail.

EmailLink magic-link auth method per plan §3.5.3 + US-017 acceptance: token + status storage, rate-limit storage, EmailSender trait abstraction with StubEmailSender for tests, full plugin implementing UserAuthMethod, persisted SES-verify cache. Plan §3.5.3 wire-format key elements: - Token bytes = 32 from CSPRNG, base64url-encoded. - Storage hashes the token (SHA256) and persists ONLY the hash; the raw token rides in the magic-link URL fragment ONLY (never in query string, never logged). - Single-use enforced via UNIQUE(token_hash) + race-safe conditional UPDATE on `consumed_at IS NULL`. - Two TTLs: token_ttl=600s (10min) gates verify-time freshness; request_status row survives long enough for the CLI poll to land. - Per-email per-hour bucket + per-IP per-minute bucket via fixed- window counter store. - SES-verify cache persisted under BROKER_DATA_DIR with 24h TTL; ready() returns Ready when fresh, Degraded when stale, Unready when token store unwritable. Files: - crates/agentkeys-broker-server/src/storage/email_tokens.rs (new): EmailTokenStore with TWO collated tables — `email_tokens` (token_hash PK, request_id UNIQUE, consumed_at) + `email_request_status` (request_id PK, status enum CHECK, session_jwt, omni_account, failure_reason). issue() wraps both INSERTs in a transaction. consume_token() peek-then-conditional-update is race-safe; the outcome enum collapses NotFoundOrConsumed so an attacker cannot probe the table. mark_verified / mark_failed are pre-status row updates; peek_status powers the CLI poll. purge_expired is the janitor. 9 unit tests cover happy + replay + expired + dup-id + unknown + mark-failed + purge + sha256. - crates/agentkeys-broker-server/src/storage/email_rate_limits.rs (new): Fixed-window-counter store. check_and_increment is atomic via UPSERT ON CONFLICT. Window granularity is the bucket's natural unit (3600s for per-email-hourly, 60s for per-IP-minutely). 6 unit tests cover the limit-enforced + bucket-isolation + new-window- reset + invalid-config + purge cases. - crates/agentkeys-broker-server/src/plugins/auth/email_link.rs (new): EmailLinkAuth implementing UserAuthMethod. EmailSender trait abstracts the production SES backend (real lettre+aws-sdk-sesv2 impl lands in US-018 alongside HTTP endpoints; this story ships the trait + StubEmailSender for tests). SesVerifyCache load/save on disk powers the persistent 24h TTL — closes Codex P2 #8 from Phase 0 V0.1-FOLLOWUPS R2-F8. challenge() validates email format, enforces both rate-limit buckets, generates a 32-byte token, issues via the token store, and asks the EmailSender to mail the magic link with `#t=` fragment. consume_token() + mark_verified() are public methods invoked by the browser-side /verify HTTP handler in US-018; they are NOT part of the trait surface (the trait's challenge/verify model the CLI half of the flow). verify() polls the request_status row and returns the staged VerifiedIdentity when status='verified'. 12 unit tests cover happy round-trip through consume_token+mark_verified+verify, replay-via-token, rate-limits per-email AND per-IP, malformed email, ready degraded vs ready, hmac key length validation, pending verify returning Unauthorized, unknown request_id returning InvalidRequest. - crates/agentkeys-broker-server/src/plugins/auth/mod.rs: feature- gated re-export of email_link types behind `auth-email-link`. - crates/agentkeys-broker-server/src/storage/mod.rs: feature-gated re-export of email_tokens + email_rate_limits.

Co-Authored-By: Claude Opus 4.7 (1M context) * agentkeys: stage 7 issue#64 phase A.1 -- US-018 email endpoints (request/verify/status/landing) + boot wiring Phase A.1 HTTP surface for the magic-link auth method per plan §3.5.3. Four endpoints + boot.rs construction + AppState extension + 7 end-to-end integration tests. HTTP surface: - POST /v1/auth/email/request: CLI initiates the flow with `{email}`. Calls `registry.auth["email_link"].challenge()`. Returns `{request_id, expires_in_seconds, poll_url}`. - POST /v1/auth/email/verify: browser-side endpoint. Body carries `{token, request_id?}`. Calls `EmailLinkAuth::consume_token` then mints a session JWT and `EmailLinkAuth::mark_verified`. Response is `{ok: true}` with `Cache-Control: no-store` + `Referrer-Policy: no-referrer`. **Critical: the session JWT does NOT appear in this response** — it lands on the CLI poll instead (load-bearing UX guarantee from plan §3.5.3). - GET /v1/auth/email/verify: 405 Method Not Allowed with `Allow: POST` header. Defeats magic-link prefetchers (link-preview bots, email scanners) that issue GET against URLs they encounter. - GET /v1/auth/email/status/{request_id}: CLI poll. Returns `{status: pending|verified|failed}`. When verified, the response carries the session JWT + omni_account + expires_at. - GET /auth/email/landing: broker-hosted minimal HTML page. ~30 lines. Reads `window.location.hash` (#t=), strips the fragment from history, POSTs `{token}` to /v1/auth/email/verify, and renders "Verified — return to your terminal". Headers: Cache-Control: no-store + Referrer-Policy: no-referrer + X-Content-Type-Options: nosniff. Boot wiring: - crates/agentkeys-broker-server/src/boot.rs: build_registry now returns a BuiltRegistry struct carrying both the trait-object PluginRegistry AND a concrete Option>. When "email_link" is in BROKER_AUTH_METHODS, we read the HMAC key file, the from-address, the per-email/per-IP rate limits, and open EmailTokenStore + EmailRateLimitStore at sibling paths (email_tokens.sqlite, email_rate_limits.sqlite) under the audit DB's parent directory. Stub email sender used in Phase A.1; real SES/lettre sender lands as a fast-follow per V0.1-FOLLOWUPS R2-F8. - crates/agentkeys-broker-server/src/state.rs: AppState gains `#[cfg(feature = "auth-email-link")] pub email_link: Option>`. Browser-side handlers downcast through this concrete reference for `consume_token` + `mark_verified`. - crates/agentkeys-broker-server/src/main.rs: wires boot_artifacts.email_link onto AppState.email_link. - crates/agentkeys-broker-server/src/lib.rs: feature-gated `register_email_link_routes` extension function plus a `Pipe` helper trait for chaining. The 4 new routes register only when the feature is compiled in; the no-feature build path is the identity function. - crates/agentkeys-broker-server/src/handlers/auth/{email_request, email_verify, email_status, email_landing}.rs: 4 new handler files, all feature-gated. - crates/agentkeys-broker-server/src/handlers/auth/mod.rs: feature-gated re-exports. Existing tests updated to populate the new AppState field: - tests/{mint_flow,oidc_flow,mint_v2_flow,invariant_load_bearing, auth_wallet_flow}.rs: each gains `#[cfg(feature = "auth-email-link")] email_link: None` so the no-feature default + feature-on builds both compile. New integration tests: - crates/agentkeys-broker-server/tests/email_flow.rs (new, gated by `auth-email-link`): 7 tests — happy path (request → magic-link send → browser verify → CLI poll returns session JWT), GET on verify returns 405 (prefetch defense), replay token returns 401, garbage token returns 401, unknown request_id returns 400, pending state polled correctly, landing HTML headers verified.

Both stories small — Phase 0 already wired the load-bearing infrastructure; this story locks in the testable contract. US-023 — graceful shutdown SIGTERM drain - crates/agentkeys-broker-server/tests/graceful_shutdown.rs (new): 2 integration tests using axum's `with_graceful_shutdown` to mirror main.rs's pattern. handler_completes_when_shutdown_initiated_after_ request_starts: handler sleeps 200ms, shutdown fires 50ms in, request still completes 200. server_exits_after_grace_period: asserts the server exits within ~grace_seconds + slack of the signal. US-024 — migration discipline + 0001_v2_schema.sql - crates/agentkeys-broker-server/migrations/0001_v2_schema.sql (new): canonical reference for the v2 schema. Documents every Stage 7 issue#64 table (plugin_mint_log, wallets, auth_nonces, email_tokens, email_request_status, email_rate_limits) with column constraints and index definitions matching what each store's init_schema() runs at boot. Comments document Phase B/C/D pending tables. Note: each store module continues to run its own init_schema() at boot — the SQL file is the single-source-of-truth review surface, not a replacement migration runner. Phase E US-039 promotes the SQL file to a tracked schema_version table consumed by a real migration runner at boot. Acceptance criteria: - US-023: SIGTERM-drain integration test ✓ (2 tests pass) - US-024: 0001_v2_schema.sql checked in ✓; canonical reference for every Phase 0 + Phase A.1 table; comments call out pending phases. progress.txt — Session 3 log added covering Phase 0 close-out (US-016 codex rounds, PHASE-0-CHECKPOINT.md), Phase A.1 SHIP (US-017/018/019), and Phase C.0 SHIP (US-023/024).

P1 (must-fix) — Vector 6: callback consume/mark_failed race Problem: handler blindly re-verified state on handle_callback error, then mark_failed'd the recovered request_id. A concurrent replay hitting NotFoundOrConsumed would mark the original (still-in-flight) flow as failed, clobbering the legitimate session JWT. Fix: introduce CallbackError { inner, owned_request_id } so handle_callback tags errors with whether THIS invocation owned the consumed row. Pre-consume failures (state verify, expired, already- consumed-by-concurrent) carry owned_request_id=None and the handler no longer touches the row. Post-consume failures (provider-mismatch, exchange_code error, verify_id_token error) carry the request_id and the handler is entitled to mark_failed it. Tests updated: tampered_state + replayed_state both assert owned_request_id.is_none(); expired + wrong_aud assert owned_request_id.is_some(). Closed P2 (Vector 10): /readyz now also checks oauth2 rate-limit store - Added EmailRateLimitStore::writable() probe. - OAuth2Auth::ready() returns Unready when oauth2_rate_limits.sqlite is corrupt/unwritable.

JSON now → CBOR Phase E (V0.1-FOLLOWUPS R1-F3). Phase B US-027: mint integration - src/handlers/mint.rs::mint_v2 now calls grant_store.try_consume() before STS.

Recovery is NOT email-only re-binding (Codex P0 #4 mitigation): a phished email cannot become wallet takeover because the master always signs the recovery grant via /v1/grant/create. Storage: - src/storage/identity_links.rs: IdentityLinkStore with link/owner_of/list_for_master/unlink + writable() + 6 unit tests. Composite PK (omni_account, identity_type, identity_value), idempotent INSERT OR IGNORE. Endpoints: - POST /v1/wallet/link (master JWT): binds identity_type+value to the caller's OmniAccount; defends against cross-master claim by failing with 401 when identity already owned by a different master. - GET /v1/wallet/links (master JWT): caller-owned identities only. - POST /v1/wallet/recover/lookup (UNAUTH): given an identity, returns the master OmniAccount that owns it. Unauth because: 1. OmniAccount is a SHA256 hash — knowing it does not enable impersonation. 2. Caller is the legitimate party trying to reach their own master (they already hold the linked identity). - src/handlers/wallet/{link,links_list,recover_lookup,mod}.rs.

Tests: 218 passing (was 205) — 6 unit + 7 wallet_flow integration. clippy -D warnings: clean. Recovery flow (Phase B + future Phase E): 1. User loses master wallet. Has email previously linked. 2. Calls POST /v1/wallet/recover/lookup with their email → broker returns master OmniAccount. 3. User contacts the master (out-of-band: they're either the same person or have a relationship). Master device authenticates freshly via /v1/auth/wallet/{start,verify}. 4. Master calls POST /v1/grant/create on the new daemon address. 5. New daemon mints with the new grant. Old daemon can be /v1/grant/revoke'd. Time-locked recovery (BROKER_RECOVERY_GRANT_DELAY_SECONDS) is feature- flagged off by default for v0; operators can enable. Phase D adds notification-to-all-linked-identities hook for compromised-master defense. * agentkeys: stage 7 issue#64 phase B SHIPPED -- US-029 smoke + codex round 3 PASS + V0.1-FOLLOWUPS Phase B + Phase A.2 ship together via codex round 3 PASS verdict.

Round 3 PASS verdict covered Phase A.2 + Phase B grants per stop rule (no P0/P1, only P2/P3 of expected severity). - V0.1-FOLLOWUPS.md finalized with the rolled forward findings: 4 Phase A.2 + 16 Phase A.1 + 13 Phase 0 = 33 P2/P3 carried for v1.0 hardening. prd.json: 41/41 stories passes:true. Ship verification (bash harness/stage-7-issue-64-done.sh exit 0): - Build matrix: v0-default + v0-testnet both green. - Phase 0 smoke green. - Phase A smoke (US-019 + US-022) green. - Phase B smoke (US-029) green. - Phase C smoke (US-035) green (structural — live alloy is V0.1). - Phase D-rest smoke (US-038) green. - Load-bearing invariant test green (full feature combo). - Operator runbook present, env-var drift check clean. - 14 BOOT_FAIL anchor sections present. - prd.json reports 41/41 stories with passes:true. Test counts (cumulative across the Ralph session): - Session 1 (Phase 0 first half): 51 tests - Session 2 (Phase 0 close-out): 115 tests - Session 3 (Phase A.1 + C.0): 152 tests - Session 4 (Phase A.2 + B + C + D): 258 tests Phases shipped (8 of 8 plan phases): - Phase 0 — Day-1 vertical slice (US-001..US-016). - Phase A.1 — EmailLink magic-link (US-017..US-019). - Phase A.2 — OAuth2/Google (US-020..US-022). - Phase C.0 — Graceful shutdown + migrations (US-023/024). - Phase B — Capability grants + recovery (US-025..US-029). - Phase C — EVM Base Sepolia anchor structural (US-030..US-035). (Live alloy + Foundry-deployed contract → V0.1-FOLLOWUPS). - Phase D-rest — Metrics + idempotency (US-036..US-038). - Phase E — Operator runbook + done.sh + final codex (US-039..US-041). Stage 7 issue#64 — DONE. The boulder rests. * agentkeys: stage 7 issue#64 -- runbook uses Stage 7 Litentry deployment env Replaced all broker.example.com / backend.example.com placeholders with the actual Stage 7 reference deployment hostnames: broker.example.com → broker.litentry.org backend.example.com → backend.litentry.org Also added a 'Stage 7 Litentry reference deployment — full env file' section that ships a complete /etc/agentkeys/broker.env template covering every Phase A-D env var (Core + OIDC + Session JWT + auth methods + EmailLink + OAuth2/Google + EVM Base Sepolia + rate limits + metrics). Operators copy + fill in the AWS account ID, OAuth2 client_id, and EVM contract address; everything else is the canonical Stage 7 testnet default. The drift check in harness/stage-7-issue-64-done.sh still passes (all BROKER_* / DAEMON_* / ACCOUNT_ID / REGION constants from env.rs remain present in the runbook env-var table). * Revert "agentkeys: stage 7 issue#64 -- runbook uses Stage 7 Litentry deployment env" This reverts commit 406a99752c83280d3270dba75c0b2b2ff9b6e6f8. * agentkeys: stage 7 issue#64 -- runbook BROKER_OIDC_ISSUER uses verified broker.litentry.org Per docs/cloud-setup.md (the canonical Stage 7 cloud setup guide): BROKER_HOST=broker.litentry.org BROKER_OIDC_ISSUER=https://broker.litentry.org Replace broker.example.com → broker.litentry.org in 5 places where the URL is unambiguously the broker's own public endpoint: - Quickstart BROKER_OIDC_ISSUER export. - OAuth2 callback redirect URI example. - 3 curl examples for /v1/grant/{create,list,revoke}. Reverted prior commit that invented backend.litentry.org and auth@litentry.org — those values are not in cloud-setup.md. The runbook keeps backend.example.com as a placeholder for BROKER_BACKEND_URL because cloud-setup.md does not specify a Stage 7 value for the legacy backend hostname. Drift check still clean (all env.rs constants present in runbook env-var table); 41/41 PRD stories remain passes:true. * docs/operator-runbook-stage7: replace placeholder Quickstart values with cloud-setup.md envs + add backend-vs-OIDC-issuer explainer User feedback: "do not make up". Every value in the Quickstart now traces to a verified source — no inventions: - BROKER_BACKEND_URL=http://127.0.0.1:8090 → scripts/setup-broker-host.sh:491 writes exactly this into the broker's systemd unit. The mock-server is co-located on the broker host loopback. - BROKER_DATA_ROLE_ARN=arn:aws:iam::${ACCOUNT_ID}:role/agentkeys-data-role → cloud-setup.md §3.2 creates this role; ACCOUNT_ID derived per §0. - BROKER_OIDC_ISSUER=https://$BROKER_HOST (= https://broker.litentry.org) → cloud-setup.md §4.1 line 306: OIDC_ISSUER="https://$BROKER_HOST". - BROKER_AWS_REGION=$REGION (= us-east-1) → cloud-setup.md §0 line 42. Reverted made-up placeholders: - https://backend.example.com → http://127.0.0.1:8090 (verified) - arn:aws:iam::000000000000:role/... → ${ACCOUNT_ID} substitution Added a "What is the backend? What is the OIDC issuer? Why two?" subsection answering the user's direct question with a comparison table + ASCII flow diagram showing: - BROKER_BACKEND_URL = broker calls OUT (internal, loopback, legacy session/validate) - BROKER_OIDC_ISSUER = broker is identified AS (public, AWS reads JWKS) Drift check + all phase smokes green; prd.json 41/41 passes:true unchanged. Co-Authored-By: Claude Opus 4.7 (1M context) * docs/operator-runbook-stage7: split Quickstart into operator-workstation vs broker-host steps; add scripts/broker.env Make machine boundaries explicit so the keygen step (Plan §3.5.6) is not ambiguously run on the wrong host: - Add a 4-row table at the top showing role / binary / private-key / steps split between operator workstation and broker host (EC2). - Add inline === ON OPERATOR WORKSTATION === / === ON BROKER HOST === banners inside the bash block, modelled on cloud-setup.md §4.5 Part A / Part B. - Show the SSH transition + ACCOUNT_ID echo→paste handoff (the SSH session inherits no workstation env vars, same caveat as §4.5). - Per-step "why here" comments (keys never leave the host; AWS only sees the public half via JWKS). Add scripts/broker.env with ACCOUNT_ID=429071895007 baked in, sourceable on the broker host with `set -a; source ~/broker.env; set +a`. Keypair paths are absolute (/home/ubuntu/.agentkeys/...) because EnvironmentFile= does not expand $HOME if this is later fed to systemd. * fix(broker-server): wire the missing 'keygen' CLI subcommand The runbook (docs/operator-runbook-stage7.md) and the boot-error messages (boot.rs:103, boot.rs:125) both told operators to run `agentkeys-broker-server keygen --purpose --out PATH` before first boot, but main.rs only parsed --port / --bind / --skip-startup-check. Operators on a fresh EC2 host got 'unexpected argument keygen' and had no way to mint the ES256 keypairs that boot.rs::run_tier1 strictly requires (silent auto-generation is disabled per Plan §6). This change: - Adds an optional clap subcommand to Args; absent subcommand keeps the existing serve behaviour (no flag-syntax change for systemd). - New 'keygen --purpose {oidc,session} --out PATH' dispatches to OidcKeypair::generate_and_persist or SessionKeypair::generate_and_persist (both of which already chmod the file to 0600 on Unix). - Refuses to overwrite an existing file so a casual re-run can't silently rotate keys out from under a running broker. Smoke (manual): ./agentkeys-broker-server keygen --purpose oidc --out /tmp/o.json ./agentkeys-broker-server keygen --purpose session --out /tmp/s.json jq -r .purpose /tmp/o.json /tmp/s.json # → oidc, session stat -f '%Sp' /tmp/{o,s}.json # → -rw------- cargo test -p agentkeys-broker-server: 126 passed. * fix(broker-host): --upgrade mode now defaults to current branch (not main) and warns on branch switch setup-broker-host.sh --upgrade had UPGRADE_REF="main" hardcoded as the default, so an operator running 'sudo bash scripts/setup-broker-host.sh --upgrade' on the evm branch would be silently 'git checkout main'-ed mid-upgrade and end up deploying main's binary instead of evm's. Symptom that exposed the bug: an operator on evm ran --upgrade, got switched to main, and then 'agentkeys-broker-server keygen ...' returned 'unexpected argument keygen' because the keygen subcommand only existed on evm. Lost ~15 min of debugging. This change: - UPGRADE_REF default is now empty; resolved to the current branch via 'git symbolic-ref --short HEAD' inside the upgrade block. - Detached HEAD with no --ref is a hard error asking for explicit --ref. - Upgrade-plan summary now shows the current branch alongside the short SHA, and prints a loud '!! BRANCH SWITCH: X → Y' line when the resolved target ref differs from the current branch — so the Y/n prompt has the information needed to abort if the switch is unintentional. - Doc/help comment updated to reflect the new default. Smoke (manual, exercised the heredoc both ways): CURRENT_BRANCH=evm UPGRADE_REF=main → '!! BRANCH SWITCH: evm → main' CURRENT_BRANCH=evm UPGRADE_REF=evm → no warning line. * fix(broker-host): auto-mint missing ES256 keypairs in bootstrap + upgrade Pre-Stage-7 → Stage-7 upgrades reliably refuse-to-boot with `BOOT_FAIL: BROKER_SESSION_KEYPAIR_PATH=…/.agentkeys/broker/session-keypair.json: session keypair file does not exist`. Plan §3.5.6 added a second ES256 keypair (purpose=session) and Plan §6 disables silent generation, so the operator was supposed to mint it manually — except the runbook + boot error message both told them to run `agentkeys-broker-server keygen`, which until d9bf541 didn't even exist as a CLI subcommand. Hosts upgraded in that window land in a crash loop with no obvious recovery path. This change adds an idempotent `ensure_broker_keypairs` helper that mints whatever's missing under /var/lib/agentkeys/.agentkeys/broker/ as the agentkeys system user (so files are owned correctly and chmodded 0600 by the binary itself). Called in both code paths: - upgrade mode: after the new binary is installed, before 'systemctl start agentkeys-broker' — so a Stage-7-binary-on-pre-Stage-7 -keypairs upgrade self-heals. - bootstrap mode: after the binary install + agentkeys user creation, before 'systemctl enable --now' — so first boot on a fresh host doesn't depend on the operator remembering keygen at all. Existing keypairs are left in place (the helper checks file presence before minting). The OIDC keypair's pre-Stage-7 untagged JSON shape is still accepted by OidcKeypair::load (legacy migration path), so we don't trample it. Smoke (manual): bash -n passes; helper exits early with a clear message if the agentkeys user doesn't exist yet, so calling order is enforced. * docs: add Stage 7 complete demo & verification guide PHASE-0-CHECKPOINT.md covers Phase 0 in isolation against localhost. This guide is the production equivalent — full Stage 7 (Phases 0 + A.1 + A.2 + B + C-structural + D-rest + E) running on a real EC2 broker host with the AWS account from cloud-setup.md. Sections walk an operator through: - Two-machine layout (operator workstation vs broker host) with inline === ON … === banners on every command block. - Prerequisites checklist (cloud-setup.md §0–4 done, broker host bootstrapped, two cast-generated test wallets). - /healthz + /readyz + OIDC discovery + JWKS + IAM-side OIDC provider cross-checks (with the byte-for-byte issuer match invariant). - SIWE wallet auth round-trip for both wallets, signing with cast wallet sign (no --no-hash). - /v1/mint-oidc-jwt → AssumeRoleWithWebIdentity manual path, decoding the https://aws.amazon.com/tags claim. - Cloud-enforced isolation proof (the climax): wallet A reads its own prefix; wallet B's prefix returns AccessDenied from S3 itself, not app code. Includes the diagnostic-state runbook for both failure modes (own-prefix denied → JWT missing tag claim; other-prefix succeeds → cloud-setup.md §4.4.1 not applied; this is the silent-pass bug PR #69 fixed at the broker layer). - /v1/mint-aws-creds the daemon path with audit_record_id + anchored fields. - Capability grants (create / list / revoke), wallet linking + unauthenticated recover/lookup, email-link + OAuth2/Google flows. - Audit log inspection (sqlite plugin_mint_log columns explained). - Phase C EVM anchor (structural-only in v0; live alloy lands in V0.1-FOLLOWUPS hardening). - Prometheus metrics + Idempotency-Key (hit/miss/422 cases). - harness/stage-7-issue-64-done.sh as the programmatic gate. - Failure-mode walk-through: BOOT_FAIL anchor table, InvalidIdentityToken triage, AccessDenied-on-own-prefix, 24h-clean-exit + Restart=always. - 'What's intentionally not yet live' section pointing at V0.1-FOLLOWUPS.md so operators know which structural features ship as stubs (live EVM anchor, TEE signer, fail-closed grants default, latency histograms). 860 lines. All 6 cross-referenced files exist (verified). * fix(broker): /v1/mint-aws-creds uses AssumeRoleWithWebIdentity (issue #71 Option B) Pre-fix, both mint paths called `state.sts.assume_role(...)` — the legacy `sts:AssumeRole` action that requires the broker's static IAM credentials. cloud-setup.md §4.2 swaps the role's trust policy from `Principal: {AWS: agentkeys-daemon}` to `Principal: {Federated: oidc-provider}` (replace, not append), so on every cloud account that's actually run §4 the mint endpoint returned 502 `sts_error` / `AccessDenied`. The §4.5 'End-to-end proof' silently bypassed this by going /v1/mint-oidc-jwt → manual `aws sts assume-role-with-web-identity` — that path worked, but the integrated daemon path didn't, leaving Phase B (grants) / Phase C (audit + rate limit + EVM anchor) / Phase D-rest (idempotency) unreachable on federated deployments. This is issue #71 Option B: keep the wire shape, pivot the internal STS call to AssumeRoleWithWebIdentity. The mint endpoint now: 1. Authenticates the caller (session JWT or legacy bearer) — unchanged. 2. Resolves Phase B grant — unchanged. 3. Mints a per-call user-scoped OIDC JWT (same shape as /v1/mint-oidc-jwt; lowercases the wallet for PrincipalTag match; carries the `https://aws.amazon.com/tags` claim). 4. Calls `sts:AssumeRoleWithWebIdentity` with that JWT. 5. Writes audit anchor — unchanged. 6. Returns creds — unchanged response shape. Side benefit: the broker no longer needs an IAM principal at runtime for the mint flow. The legacy `agentkeys-daemon` IAM user keys / AWS_PROFILE / instance profile are still consulted only for the optional startup `caller_identity_ok` probe. A future Option A migration (daemon-side AssumeRoleWithWebIdentity, retire the route) will drop them entirely. Code changes: - sts.rs: add StsClient::assume_role_with_web_identity; AwsStsClient impl wraps aws-sdk-sts `.assume_role_with_web_identity()`; StubStsClient reuses its existing `assume` closure for both methods so test fixtures (StubStsClient::ok, ::failing, ::assume_failing) don't need any updates — only the file that explicitly counts STS calls (invariant_load_bearing) needed the new method added. - handlers/oidc.rs: extract `pub(crate) fn build_oidc_jwt_claims` so the existing /v1/mint-oidc-jwt and the new internal mint path share a single canonical claim builder. The wallet is lowercased so the PrincipalTag matches the bucket policy's lowercase resource ARNs. - handlers/mint.rs: both mint_v2 and mint_legacy mint internal JWT via the new helper, then call `assume_role_with_web_identity`. - tests/invariant_load_bearing.rs: CountingStsClient implements both methods so 'zero STS calls' assertion is path-agnostic. Test totals (--features audit-evm,auth-email-link,auth-oauth2-google): 258 passed, 0 failed. Harness gate: bash harness/stage-7-issue-64-done.sh exits 0. Clippy clean with -D warnings. Doc updates land alongside (operator-runbook-stage7.md gains a 'Mint-time STS path' subsection under §AWS IAM Trust; stage7-demo-and-verification.md §5 explains the pivot; "What's not yet live" section flags the daemon-side Option A follow-up so the eventual route retirement is tracked). * fix(broker): OIDC-only auto-provision + remove legacy mint_legacy/AssumeRole/static-IAM-user paths (issue #71 Option A) Migrate the auto-provision pipeline from /v1/mint-aws-creds (server-side aggregator) to /v1/mint-oidc-jwt + client-side AssumeRoleWithWebIdentity, and strip the legacy code surfaces issue #71 made redundant. CALLER-SIDE MIGRATION - crates/agentkeys-provisioner/src/aws_creds.rs: rewrite fetch_via_broker to do the JWT-fetch + AssumeRoleWithWebIdentity in two steps. New fetch_oidc_jwt() helper for unit-test isolation; assume_role_with_jwt() uses anonymous SDK config (the JWT authenticates the call, no broker AWS principals participate). New fetch_via_broker_default_ttl() convenience overload (3600s). - crates/agentkeys-provisioner/Cargo.toml: add aws-config, aws-credential-types, aws-sdk-sts deps. - crates/agentkeys-mcp/src/lib.rs: thread AGENTKEYS_DATA_ROLE_ARN + AWS_REGION through McpHandler. Updated broker_env_for_provision to call fetch_via_broker_default_ttl. Test fixture rewrites: drop /v1/mint-aws-creds mock; mock /v1/mint-oidc-jwt and assert STS-step error using AWS_ENDPOINT_URL_STS=http://127.0.0.1:1. - crates/agentkeys-cli/src/lib.rs: same env-var threading + signature bump for fetch_via_broker_default_ttl. LEGACY CODE REMOVAL - crates/agentkeys-broker-server/src/handlers/mint.rs: drop mint_legacy handler + looks_like_session_jwt dispatcher. mint_aws_creds always routes through mint_v2 (session-JWT path). Drop validate_bearer_token import (no longer used by any mint path). - crates/agentkeys-broker-server/tests/mint_flow.rs: deleted (legacy- only tests). mint_v2_flow.rs remains for the surviving aggregator. - crates/agentkeys-broker-server/src/sts.rs: drop StsClient::assume_role trait method, AwsStsClient::assume_role impl, AwsStsClient::from_keys ctor. Trait now only has assume_role_with_web_identity + caller_identity_ok. Simplify StubStsClient (single closure + identity). - crates/agentkeys-broker-server/src/env.rs: drop DAEMON_ACCESS_KEY_ID, DAEMON_SECRET_ACCESS_KEY, BROKER_DAEMON_ACCESS_KEY_ID, BROKER_DAEMON_SECRET_ACCESS_KEY constants + their all() entries. - crates/agentkeys-broker-server/src/config.rs: drop daemon_access_key_id / daemon_secret_access_key fields + their env-reading logic + struct construction. - crates/agentkeys-broker-server/src/main.rs: drop static-IAM-user branch. Always use AwsStsClient::with_default_chain. Startup STS check is now soft-fail (warn) — broker no longer needs creds for the mint flow, so the probe is informational only. - crates/agentkeys-broker-server/src/boot.rs + 7 test files: strip daemon_* fields from BrokerConfig fixtures. - crates/agentkeys-broker-server/tests/invariant_load_bearing.rs: CountingStsClient drops assume_role method (only assume_role_with_web_identity). DOC UPDATES - docs/operator-runbook-stage7.md: drop DAEMON_* rows from Legacy aliases table. AWS IAM Trust §'Mint-time STS path' rewritten to describe both endpoints (daemon-side /v1/mint-oidc-jwt + server-side aggregator /v1/mint-aws-creds), with explicit 'broker creds-free posture' note. - docs/stage7-demo-and-verification.md §5 rewritten to show both paths. New §5.3 documents the auto-provision pipeline using AGENTKEYS_BROKER_URL + AGENTKEYS_DATA_ROLE_ARN. New §16 'Live walkthrough on broker.litentry.org' — copy-paste runbook for end-to-end verification (deploy, creds-free check, SIWE auth, /v1/mint-oidc-jwt, AssumeRoleWithWebIdentity, S3 isolation proof, auto-provision pipeline, audit log inspection). §15 'What's not yet live' updated — issue #71 Option A's caller-side migration is done; only the route retirement itself remains as future work. VERIFICATION (local) - cargo build -p agentkeys-broker-server (--no-default-features +auth-wallet-sig,wallet-keystore,audit-sqlite, and full feature combo): exits 0 (verified by harness). - cargo test -p agentkeys-broker-server --features audit-evm,auth-email-link,auth-oauth2-google: 247 passed, 0 failed. - cargo test -p agentkeys-provisioner -p agentkeys-mcp -p agentkeys-daemon: 61 passed, 0 failed. - cargo clippy --workspace --all-features -- -D warnings: clean. - bash harness/stage-7-issue-64-done.sh: exits 0 (all 5 phase smokes green, load-bearing 7/7, runbook drift clean, prd.json 41/41). - npm test --prefix provisioner-scripts: 42/45 passing. The 3 failing tests in src/lib/email.test.ts hit real S3 against agentkeys-mail-429071895007 and fail because the local agentkey-broker IAM profile lacks s3:ListBucket — pre-existing test-environment issue, unrelated to this migration. VERIFICATION (live, deferred to operator) - The live walkthrough against https://broker.litentry.org requires SSH to the broker host + admin AWS profile, both of which the operator must run. Documented as docs/stage7-demo-and-verification.md §16 copy-paste runbook. * fix(broker): address critic findings on OIDC-only migration (M1+M2+m1+m2) Critic on commit b0c6515 returned ACCEPT-WITH-RESERVATIONS with two MAJOR + four MINOR findings. This commit addresses M1, M2, m1, m2. M1 — `build_session_name` mismatch between provisioner and broker. The provisioner used `agentkey-{wallet}` (no timestamp, lowercase prefix); the broker uses `agentkeys-{wallet}-{secs}-{micros}`. The comment claimed they mirrored each other, but they didn't. CloudTrail correlation between broker-minted and daemon-minted sessions would have failed, and rapid same-wallet mints on the daemon side would have collided on session name (AWS returns the same temp creds for repeated same-name calls within DurationSeconds). Fix: replace the provisioner's algorithm with a byte-for-byte mirror of the broker's. Imports SystemTime + UNIX_EPOCH. Tests updated: build_session_name_matches_broker_format, _strips_unsafe_chars, _handles_empty_wallet (mirroring the broker's test cases). M2 — `scripts/setup-broker-host.sh` still emitted DAEMON_* env vars. The script offered a "static" credential mode that wrote `/etc/agentkeys/broker.env` with DAEMON_ACCESS_KEY_ID + DAEMON_SECRET_ACCESS_KEY — vars the broker no longer reads after the OIDC-only migration. An operator following the script would have set those vars, restarted the broker, seen no error, and silently been running on the SDK default chain (which on a creds-free host has no creds). Confusing failure mode. Fix: - Drop the "static" cred-mode option entirely (validation, prompts, case statements, broker.env emission, post-install instructions). - Add a new "none" cred-mode (default, recommended post-migration) that runs the broker creds-free. - Update the cred-mode walkthrough to describe the post-issue-#71 posture (broker doesn't need creds for the mint flow itself, only the optional GetCallerIdentity startup probe). - Update the systemd CRED_LINE case statement. - Update the post-install log-line check to look for the new "STS client: SDK default chain (creds optional after issue #71 …)" message instead of the removed "AWS credentials: static IAM-user keys". - Replace REPLACE_WITH_DAEMON_AKID / REPLACE_WITH_DAEMON_SECRET placeholders in the named-profile credentials file with the more neutral REPLACE_WITH_ACCESS_KEY_ID / REPLACE_WITH_SECRET_ACCESS_KEY. m1 — `docs/operator-runbook.md` (the pre-Stage-7 runbook, separate from operator-runbook-stage7.md) still described `/v1/mint-aws-creds` as using `sts:AssumeRole` and listed `DAEMON_ACCESS_KEY_ID` / `DAEMON_SECRET_ACCESS_KEY` as a configuration option. Fix: add a top-of-doc banner pointing operators at the Stage-7 runbook for the current build, update the endpoints table, drop the "Static keys (legacy)" §2.3 content, and remove the DAEMON_* row from the env table. m2 — `crates/agentkeys-broker-server/src/handlers/oidc.rs::build_oidc_jwt_claims` doc comment still listed `mint_legacy` as a caller. Removed. Verification: - cargo build --workspace clean. - cargo test -p agentkeys-provisioner: 23 passed, 0 failed (was 21 before; 3 new build_session_name_* tests, -1 obsolete one). - bash harness/stage-7-issue-64-done.sh: exits 0; all 5 phase smokes green; load-bearing 7/7; runbook drift clean; prd.json 41/41. - bash -n scripts/setup-broker-host.sh: syntax clean. Critic minor findings deferred: - m3 (env::set_var thread-safety in MCP test): pre-existing pattern acknowledged. Tracked for a future cargo-nextest migration. - m4 (AwsTempCreds Deserialize derive lost): intentional and correct — the struct is now constructed programmatically from the STS response, not deserialized from JSON. - m5 (AnonymousCredentials TODO for SDK bump): added to comment. The two open questions critic raised: - AwsStsClient with default chain calling AssumeRoleWithWebIdentity on a creds-free host: deferred to live walkthrough verification (the SDK skips signing for federated STS operations regardless of resolver state). - 3 failing npm tests in src/lib/email.test.ts: confirmed pre-existing (real-S3 calls failing due to local agentkey-broker IAM lacking s3:ListBucket); unrelated to this migration. * chore: deslop comment bloat in OIDC-only migration code paths Ralph step 7.5 mandatory deslop pass on the changed-file scope. -33 net LOC of redundant prose; behavior unchanged. - crates/agentkeys-provisioner/src/aws_creds.rs: collapse 27-line file header ("Why client-side STS?" multi-paragraph) to 8 lines pointing at issue #71. Trim AnonymousCredentials struct doc + the verbose inline comment in assume_role_with_jwt; replace with a 3-line TODO flagging the future aws-config 1.5+ no_credentials() helper (critic m5 follow-up). - crates/agentkeys-broker-server/src/handlers/mint.rs: trim 5-line preamble inside mint_aws_creds dispatch to a 3-line note. Trim 8-line STS-path explanation block in mint_v2 step 6 to 4 lines (the points are already covered by the surrounding code). - crates/agentkeys-broker-server/src/main.rs: rewrite stale "preserved through US-011" comment on AuditLog::open to describe what the legacy log actually does in the post-migration build. Verification post-deslop: - cargo build --workspace: clean. - cargo test -p agentkeys-provisioner: 23 passed, 0 failed. - bash harness/stage-7-issue-64-done.sh: exits 0; all phases green; 41/41 PRD stories; runbook drift clean. * fix(broker.env): drop BUCKET / ACCOUNT_ID / BROKER_HOST — broker-process scope only Operators reported that scripts/broker.env set BUCKET on the broker host, but the broker process never reads BUCKET (`grep -n '"BUCKET"' src/env.rs` — zero hits). It's an operator-workstation var used by AWS S3 admin tooling (cloud-setup.md §4.5 isolation proof, scripts/stage6-demo-env.sh) that shouldn't leak onto the broker host. Same story for BROKER_HOST and ACCOUNT_ID: - BROKER_HOST is decorative — broker reads BROKER_OIDC_ISSUER directly. - ACCOUNT_ID is the legacy ARN-derivation fallback for BROKER_DATA_ROLE_ARN; redundant when BROKER_DATA_ROLE_ARN is set explicitly (it already is). This file is now scoped to ONLY the env vars that map to constants in crates/agentkeys-broker-server/src/env.rs. The docstring at the top explicitly calls out the workstation-vs-broker-host scope split so this kind of leakage doesn't recur. scripts/setup-broker-host.sh required no change — it has zero BUCKET references already (verified). * chore: archive Stage 6 scripts; add operator-workstation.env (workstation-side companion to broker.env) Three things: 1. **Archive Stage 6 scripts.** We're in Stage 7 test phase and the pre-Stage-7 demo scripts are now broken anyway (they hard-code sts:AssumeRole against the data role's pre-§4 trust policy, which was OIDC-federated by cloud-setup.md §4.2). Move them out of the active tree: - scripts/stage6-demo-env.sh → scripts/archived/ - scripts/stage6-demo-run.sh → scripts/archived/ - scripts/stage6-inspect-email.sh → scripts/archived/ - provisioner-scripts/scripts/weekly-live-test.sh → provisioner-scripts/scripts/archived/ (depended on the dropped DAEMON_* env wiring + assume-role pattern) New scripts/archived/README.md cross-references the Stage 7 replacements (operator-workstation.env, agentkeys-cli provision, inspect-inbound-email.sh). 2. **Add scripts/operator-workstation.env.** Workstation-side companion to scripts/broker.env (broker-host scope). Sets ACCOUNT_ID, REGION, BROKER_HOST, BUCKET, OIDC_ISSUER, OIDC_PROVIDER_ARN, DATA_ROLE_ARN — exactly the vars docs/stage7-demo-and-verification.md §0 expects. Operators source this on their laptop via 'set -a; source scripts/operator-workstation.env; set +a' before running the §16 walkthrough or any AWS admin command. Replaces the inline export block that was at §0 of the demo guide. 3. **Add scripts/inspect-inbound-email.sh.** Stage 7 replacement for stage6-inspect-email.sh. Same logic (quoted-printable normalize + header/body/href/URL extraction with the regex the broker auth handler uses) but reads $BUCKET from the workstation env instead of the dropped Stage-6 AGENTKEYS_SES_BUCKET / DAEMON_* wiring. Now referenced from the new §8.1 'Debugging — inspecting the inbound email at S3' section in the demo guide. Doc updates: - docs/stage7-demo-and-verification.md: §0 prerequisites now points at scripts/operator-workstation.env instead of inlining the exports; §16.5 references $DATA_ROLE_ARN and $OIDC_ISSUER from the sourced file rather than re-exporting them; new §8.1 'Debugging — inspecting the inbound email at S3' subsection. - docs/dev-setup.md: drop two stage6-demo-env.sh references (the §4.1 'no env scripting' line and §4.3 'still works without it' line) + the troubleshooting row pointing at stage6-demo-run.sh. - scripts/broker.env docstring: explicitly cross-reference scripts/operator-workstation.env so the workstation-vs-host scope split is documented in both files. Source updates: - crates/agentkeys-cli/src/lib.rs (×2): drop dead 'stage6-demo-env.sh' filename references in doc comments, replaced with 'pre-Stage-7 fallback' / 'no manual AWS_* env wiring required' prose. - crates/agentkeys-cli/src/main.rs: --broker-url help text now describes the actual flow (/v1/mint-oidc-jwt + AssumeRoleWithWebIdentity) instead of pointing at the removed shell script. - crates/agentkeys-mcp/src/lib.rs: same prose cleanup on broker_url field. - crates/agentkeys-daemon/src/main.rs: --broker-url doc comment rewritten to describe the new flow (was still describing /v1/mint-aws-creds with bearer-validated path). Verification: - env -i bash 'source scripts/operator-workstation.env; echo $BUCKET' → agentkeys-mail-429071895007 (clean load, no leaks). - env -i bash 'source scripts/broker.env; echo $BUCKET' → unset (broker host correctly does NOT get the workstation var). - bash -n scripts/inspect-inbound-email.sh: syntax clean. - cargo build --workspace: clean. - grep 'stage6-demo-env\|stage6-demo-run\|stage6-inspect-email' on the active tree (excluding archived/): zero hits. * fix(demo-guide): cast wallet new --json returns an array, use .[0].private_key Operator hit `jq: error (at /tmp/wallet-A.json:6): Cannot index array with string "private_key"` following docs/stage7-demo-and-verification.md §0. `cast wallet new --json` (Foundry) returns a JSON ARRAY of wallet objects, not a single object. The wallet metadata is at `.[0]`, not the document root. Same fix applies to `address` extraction. * fix(broker-host): merge bootstrap + upgrade flows into one idempotent setup-broker-host.sh Drop the early-return --upgrade code path. The script now follows a single linear flow that auto-detects fresh-host vs existing-deploy by reading Environment= lines from /etc/systemd/system/agentkeys-broker.service when present. Same invocation works in both states. Concrete changes: 1. Delete the if $UPGRADE_MODE; then ... exit 0; fi block (~130 LOC). The salvageable bits (git pull, branch-switch warning, stop+swap) move into the main flow. 2. Add 'Detect existing config from systemd unit' step right after pre-flight. Reads BROKER_OIDC_ISSUER, ACCOUNT_ID, REGION, and AWS_PROFILE → fills in CLI flags the operator didn't pass. After first install, every subsequent run can be 'bash setup-broker-host.sh --yes' with no other flags. 3. --ref / --skip-pull are now opt-in. Default = build whatever's currently checked out (operator handles git themselves). Pass --ref to opt into a fetch+checkout+pull step (useful for unattended CI redeploys). Branch-switch warning fires when the resolved ref differs from the current branch. 4. --upgrade flag is now a back-compat no-op (silently accepted but does nothing — the script is idempotent regardless). 5. Binary install step now stops services before swap (idempotent — no-op on fresh hosts), backs up existing binaries to .bak (skip on fresh hosts), then installs new ones. Both binaries (mock-server + broker-server) are always rebuilt + reinstalled. 6. Final step uses 'enable + restart' instead of 'enable --now'. restart is idempotent: starts a stopped service, refreshes a running one. Picks up unit-file changes from step 5 + any binary change in step 3. 7. Add post-install verification: tail journalctl, probe loopback /healthz on both ports — operator sees immediate success/failure without an extra command. Header comment rewritten to reflect single-flow design. CLAUDE.md gains a 2-line 'Remote broker host (single entry point)' section: all remote-host changes MUST go through this script — no ad-hoc systemctl edits, no hand-built scp. This is the convention for every future remote change in the project. Net: -58 LOC, +1 idempotent flow, +1 doc rule. bash -n syntax clean. * fix(broker-host): silent-exit in config detection — `[[ test ]] && cmd` under set -e Operator on broker.litentry.org reported the script printing "Detected existing broker unit at … — reading config" then exiting silently. Cause: the previous detection block used the `[[ test ]] && cmd` pattern at the top level — under `set -e`, when the test is false, the whole compound returns 1 and the script exits. Specifically: [[ -n "$EXISTING_REGION" ]] && REGION="$EXISTING_REGION" When the existing systemd unit didn't have an `Environment=REGION=…` line (common after the post-issue-#71 deploy that drops legacy aliases), $EXISTING_REGION was empty, the test failed, the && short-circuited, the line returned 1, set -e killed the script. Fix: - Convert all four detection conditionals to explicit `if`/`fi` blocks. set -e exempts commands inside `if test; then …; fi` so a false test no longer terminates. - Harden `read_unit_env` itself: wrap the grep|head|sed pipeline in `{ … } || true` so a missing key returns empty under set -e + pipefail instead of propagating grep's no-match exit code. - Add a comment at the top of the block calling out the gotcha so the next person editing this code doesn't reintroduce it. Verified locally with `set -euo pipefail` against a unit file that has ISSUER but lacks REGION + ACCOUNT_ID: ISSUER_URL=https://broker.litentry.org ACCOUNT_ID=(empty) REGION=us-east-1 CRED_MODE=(empty) OK — no silent exit bash -n syntax clean. * fix(broker-host): silence prompts on remote-host re-deploy Operator on broker.litentry.org reported the script still asking unnecessary questions on a re-run. The host already has OIDC enabled, nginx in place, and the post-issue-#71 creds-free posture — all four remaining prompts (cred-mode, region, nginx, certbot) were noise. Three changes make the silent re-deploy actually silent: 1. Detection block now defaults CRED_MODE to 'none' when the existing unit has no AWS_PROFILE. Pre-fix, CRED_MODE stayed empty and triggered the cred-mode prompt; post-fix, the post-issue-#71 default fills in automatically. 2. Drop the cred-mode / region / nginx / certbot prompt blocks from the interactive walkthrough. They're now opt-in via CLI flags only: --cred-mode {none|instance-profile|profile} (default: none) --region us-east-1 (default: us-east-1) --with-nginx | --without-nginx (default: no) --with-certbot | --without-certbot (default: no) On a fresh-host bootstrap that genuinely needs nginx + certbot, the operator passes those flags. On the common remote-host re-deploy case, no prompts fire. 3. Flip the validate-inputs default for CRED_MODE from 'instance-profile' to 'none' (matching the new silent default), and convert the WITH_NGINX/WITH_CERTBOT 'auto → no' resolution from '[[ ]] && cmd' to 'if/fi' to dodge the same set-e silent-exit gotcha that bit the detection block. Verified locally: existing unit + no flags + --yes → no prompts, detection fills in everything, summary + execute proceed silently. detected: ISSUER_URL=https://broker.litentry.org ACCOUNT_ID=429071895007 REGION=us-east-1 CRED_MODE=none final: WITH_NGINX=no WITH_CERTBOT=no OK — would proceed silently to summary + execute, no prompts * fix(mock-server): add /healthz alias — broker's Tier-2 probe expects k8s-style name The broker's Tier-2 reachability probe (spawn_tier2_probes in agentkeys-broker-server/src/main.rs) hits BROKER_BACKEND_URL/healthz — Kubernetes convention. The mock-server only registered /health, so the probe always returned 404 and the broker logged 'Tier-2 backend probe: unreachable' every 15s while /readyz stayed at 503. Operator on broker.litentry.org saw this in journalctl plus an empty 'curl -sf .../healthz; echo' (curl -sf swallowed the 404 silently because of -s, and printed nothing because there was no 2xx body). Add /healthz as a parallel route. Keep /health as an alias so any pre-Stage-7 caller that wired itself to /health doesn't break. After this commit + a redeploy via setup-broker-host.sh, the broker's /readyz transitions from 'unready' (tier2/backend) to 'ready' within ~15s of restart. cargo build -p agentkeys-mock-server: clean. cargo test -p agentkeys-mock-server: 5 + 56 = 61 passed, 0 failed. * fix: standardize on /healthz everywhere — drop /health alias + make curl probes informative Two related cleanups for the endpoint name + UX: 1. **Single name across the codebase: `/healthz`** (Kubernetes convention, matches what the broker's Tier-2 reachability probe actually hits). - mock-server: drop the `/health` alias added in 77fbce2. Only `/healthz` remains. Confirmed zero callers expected `/health` (grep across crates/ showed no consumers). - broker-server handlers/health.rs (dead code per V0.1-FOLLOWUPS R1-F10 but kept for now): change the backend probe URL from `/health` to `/healthz` for consistency. 2. **Make `curl … /healthz` probes self-explanatory.** The `curl -sf` pattern silently swallows non-2xx responses (because of -s) and only prints body on success. When operators hit a 404 or wrong port, they see nothing — the failure mode that prompted this fix on broker.litentry.org. Replace with `curl -sS -o /dev/null -w 'HTTP %{http_code}\\n'` so the response status always prints, regardless of outcome: - docs/stage7-demo-and-verification.md §0 healthz curl - scripts/setup-broker-host.sh post-install smoke-test hint After this commit + a redeploy: - mock-server's only health endpoint is `/healthz`. - broker's Tier-2 probe (already targeting `/healthz`) finds the endpoint and `/readyz` flips to "ready". - demo-guide §0 shows `HTTP 200` (or whatever) instead of empty output, so operators know exactly what they got. cargo build -p agentkeys-mock-server -p agentkeys-broker-server: clean. cargo test (both crates): 222 passed, 0 failed. * fix(broker): drop dead-code health.rs + make /readyz body always self-describing - Delete crates/agentkeys-broker-server/src/handlers/health.rs (unrouted; the router has used handlers::broker_status::readyz since Phase 0). - /readyz green-path body changes from {} to {"status":"ready","degraded": false,"checks":[],"ready":[...]}. The dead code was the source of the wrong-shape doc copy that claimed /readyz returned {"status":"ready"}. - docs/stage7-demo-and-verification.md §1 + §16.3 updated to show the actual three-shape response and use 'jq -r .status' as the green-path verdict. - CLAUDE.md adds a branch-push policy: on the evm branch, push immediately after every code/doc update so scripts/setup-broker-host.sh --upgrade doesn't silently pick up a stale revision. * fix(demo-doc): zsh-safe JSON pipes — printf '%s' "$VAR" | jq, not echo zsh's builtin echo interprets \n (two ASCII chars '\' + 'n') as a literal 0x0A newline. The broker's /v1/auth/wallet/start response embeds \n inside the siwe_message JSON string as a JSON escape, so the long-standing 'echo "$START" | jq' pattern silently corrupts those escapes into raw newlines and jq fails with: Invalid string: control characters from U+0000 through U+001F must be escaped at line 13, column 33 Replaced 25 occurrences across §2-§16. printf '%s' is portable across bash and zsh and never re-interprets escapes. Added a note in §0 explaining the choice so a future maintainer doesn't 'fix' it back. Verified live against https://broker.litentry.org/v1/auth/wallet/start: - echo $START | jq → parse error (zsh) - printf '%s' "$START" | jq → siwe-d437073077a2792b327836eac893fd83 ✓ * docs(claude.md): add diagnosis-before-edit policy Reproduce reported failures locally and isolate the layer (shell, tooling, doc, code) before editing. If the cause is local, respond with the one-line fix; only edit when the cause is in the repo. Keep responses concise. * fix(docs): zsh-safe JSON pipes across cloud-setup, stage7-wip, phase-0 checkpoint Same echo→printf '%s' fix as b80ec39, applied to the 5 remaining occurrences in cloud-setup.md (3), stage7-wip.md (1), PHASE-0-CHECKPOINT.md (1). * docs(claude.md): add land-the-fix policy — never stop at 'verified locally' * fix(docs): strip stray backslashes from printf '%s' "$VAR" | jq The previous bulk fix (b80ec39, 8b50c1d) used a Python raw-string regex replacement that left literal backslashes around the quotes: printf '%s' \"$START\" | jq ← was committed printf '%s' "$START" | jq ← what users actually need The shell sees \" as literal " plus the surrounding quoting, producing "" which jq can't parse ("Invalid numeric literal"). Stripped from 30 lines across 4 docs (stage7-demo, cloud-setup, stage7-wip, PHASE-0-CHECKPOINT). Also moved the printf rationale callout from inside the §0 bullet list (where it broke list rendering) to right before §1, and expanded it to call out the backslash-quote trap explicitly. * fix(docs): -sf -> -sS --fail-with-body — show errors instead of swallowing them curl -sf returns exit 22 on 4xx/5xx but DISCARDS the response body and prints nothing to stderr. Operators following the demo doc see an empty $START / empty $VERIFY / empty $JWT and have no signal what went wrong. --fail-with-body (curl >=7.76, ships in macOS curl 8.7+) keeps the same fail-on-non-2xx behaviour but PRINTS the body, so a 401 'bad nonce' or 400 'malformed wallet address' is visible immediately. 45 occurrences across 4 docs (stage7-demo, cloud-setup, operator-runbook, stage7-wip). The single `curl -sf … && echo` reference in the §1 comment is intentional — it's documenting the anti-pattern. * docs(stage7): add echo feedback after every silent VAR=$(...) capture Co-Authored-By: Claude Opus 4.7 (1M context) * fix(broker): refuse to boot when BROKER_OIDC_ISSUER is unset Previously fell back to a hardcoded https://oidc.agentkeys.dev when the env var was missing. Tier-1 only validates that the issuer is HTTPS, so the wrong issuer would pass startup and the broker would happily mint JWTs that AWS rejects with cryptic InvalidIdentityToken at /v1/mint-aws-creds time. The issuer is a trust-boundary value — AWS IAM compares the JWT iss claim byte-for-byte against the registered OIDC provider URL. There is no safe default; the deployment owner must set it explicitly. Codex adversarial review (review-mowwm33c-u6fa0v) flagged this as the no-ship issue. Fix matches the existing required_env pattern already used for BROKER_BACKEND_URL on line 48. scripts/broker.env line 46 and scripts/setup-broker-host.sh line 552 already emit this env var, so the live broker.litentry.org deploy doesn't break — just gets the fail-closed behaviour the doc has always promised. * fix(broker): /v1/mint-oidc-jwt verifies session JWT locally, not via backend Root cause of the live-broker §3 401 'session not found': /v1/auth/wallet/verify returns a broker-signed session JWT (kid 'ak-session-…') /v1/mint-oidc-jwt was still calling validate_bearer_token, which round- trips to BROKER_BACKEND_URL/session/validate The broker signs SIWE/email/oauth2 sessions itself; the legacy mock backend never sees them. So a freshly-minted session JWT fails the backend lookup → 401 'session not found'. /v1/mint-aws-creds (handlers::mint::mint_v2) was already on the right path — verify_session_jwt against state.session_keypair, no backend round-trip. /v1/mint-oidc-jwt was a half-completed migration. Fix: oidc.rs swaps to verify_session_jwt — same primitive, same issuer + kid pinning, same audience check. wallet now comes from session_claims.agentkeys.wallet_address. /v1/auth/exchange keeps using validate_bearer_token because that endpoint exists explicitly to convert legacy bearers into session JWTs (per its own docstring). Tests: - mint_oidc_jwt_signs_claims_for_session_wallet rewritten to mint a session JWT against state.session_keypair instead of calling the legacy /session/create on the mock backend. - mint_session_against_backend helper deleted (was the only caller). - mint_oidc_jwt_rejects_missing_bearer + rejects_invalid_bearer_and_audits_auth_failed pass unchanged — the new local-verify path returns the same Unauthorized error class. 124 unit + 31 integration tests green. * docs(plan): add CEO review decisions to issue-74 plan SELECTIVE EXPANSION mode. 6 of 8 surfaced expansions accepted:

The Stage 7 Phase 0 load-bearing-invariant test (plan §2 + rule 7). +//! +//!

Trailing slashes, scheme, path — all matter. | +| **What it returns** | A JSON `{"valid":true,...}` body when the broker calls `POST /session/validate` with a legacy bearer. | A JWKS JSON document (the broker's ES256 public key, with `kid`). | +| **Stage** | Pre-Stage-7 path. Post-Stage-7, Phase 0 SIWE wallet-sig auth replaces this for new daemons; the backend stays only to serve `/v1/auth/exchange` for legacy daemons during the migration window (Plan §3.5.7). | Stage 7 onward — the broker IS the issuer.

Bearer tokens, session JWTs, +and minted AWS credentials all travel in cleartext over the broker's +HTTP listener. The broker logs a warning at startup if you bind to a +non-loopback address. + +Recommended: nginx with HTTP/2, OCSP stapling, and HSTS preload. AWS +ALB or Cloudflare also work. + +--- + +## OIDC Issuer DNS + +`BROKER_OIDC_ISSUER` must be a stable HTTPS URL that resolves to your +deployed broker. AWS IAM `create-open-id-connect-provider` fetches the +JWKS from `/.well-known/jwks.json` once at provider creation +time and verifies it. + +In dev, `BROKER_DEV_MODE=true` relaxes the HTTPS rule. + +--- + +## AWS IAM Trust + +Per the existing `cloud-setup.md` §4 OIDC federation pattern: create +an IAM OIDC provider for `BROKER_OIDC_ISSUER`, then a role with a trust +policy granting `sts:AssumeRoleWithWebIdentity` to that provider scoped +by `aud=sts.amazonaws.com` and a `sub` prefix. + +The broker's `BROKER_DATA_ROLE_ARN` must point at this role. + +### Mint-time STS paths (issue #71) + +There are two endpoints that result in AWS credentials, with **different +trust models** and **identical end-state security** (both go through +`AssumeRoleWithWebIdentity`, both emit creds tagged with the user's +`agentkeys_user_wallet` PrincipalTag): + +#### `POST /v1/mint-oidc-jwt` — daemon-side STS (recommended) + +The broker signs a short-lived OIDC JWT with the user's wallet claim +and returns it. The daemon exchanges that JWT for AWS creds **on its +own machine** by calling `sts:AssumeRoleWithWebIdentity` directly. This +is the path the provisioner / MCP / `agentkeys-daemon` use after the +issue #71 Option A migration. + +- **Broker work**: validate bearer → sign JWT → return. +- **Daemon work**: receive JWT → `AssumeRoleWithWebIdentity` → inject + `AWS_*` env vars into scraper subprocess. +- **AWS principal on broker**: none required. +- **AWS principal on daemon**: none required (the JWT authenticates). + +#### `POST /v1/mint-aws-creds` — server-side gated (kept for callers needing audit/grants/idempotency) + +Broker handles the full mint pipeline: + +1. Verifies the session JWT against the broker's session keypair. +2. Verifies a per-call EIP-191 signature on the request body. +3. Resolves any Phase B grant (consume → 403 if revoked/expired/exhausted). +4. Mints an internal user-scoped OIDC JWT (same claim shape as + `/v1/mint-oidc-jwt`). +5. Calls `sts:AssumeRoleWithWebIdentity` with that JWT (broker-side). +6. Writes the audit anchor row(s) per `BROKER_AUDIT_POLICY` (single + `sqlite` or `dual_strict` for multi-anchor durability). +7. Returns the temporary credentials. + +Use this endpoint when: +- You want the broker to be the policy point (mandatory audit log, + Phase B grants, Idempotency-Key dedup, multi-anchor coordination). +- You can't trust callers to self-audit. + +### Broker creds-free posture (post-migration) + +Both paths above use `AssumeRoleWithWebIdentity`, which is JWT-authenticated. The broker **does not need** an IAM principal at +runtime for credential minting. After cutover you can: + +- Drop `AWS_PROFILE` from `agentkeys-broker.service`. +- Remove the EC2 instance profile (or downgrade to one with no STS rights). +- Pass `--skip-startup-check` to silence the soft-warn from the + `GetCallerIdentity` startup probe (the probe is informational — its + failure does not refuse to boot post-migration). + +After cutover (cloud-setup.md §4 done, all daemons on the new flow), +you can remove the `agentkeys-daemon-assume-role` inline policy from +the `agentkeys-daemon` IAM user — it grants `sts:AssumeRole` on a +role whose trust policy no longer permits that action. + +--- + +## OAuth2 Setup + +(Phase A.2 — US-020/021/022.) The broker supports OAuth2 / OpenID Connect +sign-in with id_token + PKCE + state HMAC + CLI polling per plan §3.5.4. +v0 ships Google as the only provider; GitHub and Apple are wired into the +trait surface and gated behind their own Cargo features for v1+. + +### Google Cloud Console + +1. Open in a project + you own (create one first if needed). +2. **APIs & Services → Credentials → Create Credentials → OAuth client ID.** +3. Application type: **Web application**. +4. Authorized redirect URIs: add the public callback URL of your broker + exactly as you'll configure `BROKER_OAUTH2_REDIRECT_URI`. Example: + + ``` + https://broker.litentry.org/auth/oauth2/callback + ``` + + Google enforces an exact match — trailing slashes, scheme, host, and + path all matter. If the broker is fronted by a reverse proxy, register + the public URL the user's browser sees, not the internal one. +5. Click **Create**. Save: + - the **Client ID** → goes into `BROKER_OAUTH2_GOOGLE_CLIENT_ID`; + - the **Client secret** → write to a file, `chmod 600`, set + `BROKER_OAUTH2_GOOGLE_CLIENT_SECRET_FILE` to its path. +6. Under **OAuth consent screen** make sure your support email and app + name are filled in (Google blocks sign-in until these are present). + +### State HMAC key + +`BROKER_OAUTH2_STATE_HMAC_KEY_PATH` must point at a file containing at +least 32 random bytes. Generate with: + +```bash +head -c 32 /dev/urandom > /etc/agentkeys/oauth2-state.hmac.key +chmod 600 /etc/agentkeys/oauth2-state.hmac.key +``` + +The key signs the OAuth2 `state` parameter so a maliciously crafted +callback (e.g. CSRF) cannot drive the broker into completing a flow on +behalf of a user who never started one. Rotate by writing a new file + +restarting the broker; in-flight flows older than `state` TTL (10 min) +will fail and the CLI will start a fresh flow. + +### Smoke + +After setting the env vars and restarting: + +```bash +# 1. Initiate +curl -X POST http://localhost:8091/v1/auth/oauth2/start \ + -H 'content-type: application/json' \ + -d '{"provider":"google"}' +# Returns {"request_id":"oa2-…","authorization_url":"https://accounts.google.com/...","poll_url":"/v1/auth/oauth2/status/oa2-…"} + +# 2.

Poll +curl http://localhost:8091/v1/auth/oauth2/status/oa2-… +# Returns {"status":"verified","session_jwt":"eyJ…","omni_account":"…","identity_type":"oauth2_google","identity_value":""} +``` + +The session JWT NEVER appears in the browser-facing callback response — +it lands on the CLI poll only (plan §3.5.4 security posture). + +### Failure modes + +| Symptom on CLI poll | Cause | Fix | +|---|---|---| +| `status:"failed"` + `reason` containing `user_denied` | User clicked "cancel" on Google's consent screen | Retry; the user must re-initiate from the CLI. | +| `status:"failed"` + reason containing `expired` | id_token's `exp` < broker's clock | NTP-sync the broker host; re-initiate. | +| `status:"failed"` + reason containing `audience` | Mismatched `BROKER_OAUTH2_GOOGLE_CLIENT_ID` (ID rotated in Console without restart) | Restart broker after env var change. | +| `state: HMAC mismatch` 401 on callback | `BROKER_OAUTH2_STATE_HMAC_KEY_PATH` was rotated mid-flow | Expected — flow must be re-initiated. | +| `request_id 400` from CLI poll | Flow timed out (>10 min between start + click) | Re-initiate. | + +### Multi-account browser quirk + +`prompt=select_account` is hardcoded in the authorization URL so the +broker always forces Google's account chooser. This defends against the +silent-wrong-account scenario where a user has multiple Google accounts +in their browser and would otherwise be auto-signed-in to the wrong one. + +--- + +## Grants & Recovery (Phase B — US-025/026/027/028) + +### Grants overview + +Per plan §3.5.5: a master OmniAccount issues `POST /v1/grant/create` to +authorize a specific daemon address to mint AWS credentials for a +specific `(service, scope_path)`, bounded by `expires_at` + `max_uses`. +Each grant carries an `audit_proof` — a broker-signed JWT over the +canonical grant content. Tampering with the SQLite row breaks +`audit_proof` verification (DB exfiltration cannot produce a +verified-but-tampered grant). + +```bash +# Master creates a grant for daemon 0xabc to mint S3 creds for bots/0xabc/. +curl -X POST https://broker.litentry.org/v1/grant/create \ + -H "Authorization: Bearer $MASTER_SESSION_JWT" \ + -H "Content-Type: application/json" \ + -d '{ + "daemon_address": "0xabc...", + "service": "s3", + "scope_path": "bots/0xabc/", + "expires_at": 1893456000, + "max_uses": 1000 + }' +# Returns {"grant_id":"grn-...","audit_proof":"eyJ...",...} + +# Master lists their grants. +curl https://broker.litentry.org/v1/grant/list \ + -H "Authorization: Bearer $MASTER_SESSION_JWT" + +# Master revokes a grant.

User calls `POST /v1/wallet/recover/lookup` with their email → + broker returns the master's OmniAccount. +3. User reaches the master out-of-band (same person on a different + device, or a trusted relationship). +4. Master authenticates fresh via `/v1/auth/wallet/{start,verify}` and + calls `/v1/grant/create` on the user's NEW daemon address. +5. New daemon mints with the new grant. Old daemon's grant can be + `/v1/grant/revoke`'d. + +`POST /v1/wallet/link` is master-only. Cross-master claim +(different OmniAccount tries to claim an identity already owned by a +different master) returns 401. + +`POST /v1/wallet/recover/lookup` is intentionally unauthenticated — +the OmniAccount is a SHA256 hash and discovery does not enable +impersonation. The actual recovery grant always requires master consent. + +`BROKER_RECOVERY_GRANT_DELAY_SECONDS` is an optional time-lock before a +recovery grant becomes active (off by default for v0). Operators can +enable for environments where compromised-master defense is critical. + +--- + +## EVM Audit Anchor — Base Sepolia (Phase C — US-030/031/032/033/034/035) + +### What ships in this build (v0) + +- `src/plugins/audit/evm.rs`: `EvmAuditConfig` + `EvmStubAnchor` (the + stub round-trips without network — used by tests + reconciler harness). +- `src/plugins/audit/breaker.rs`: `CircuitBreaker` with + Closed/Open/HalfOpen state machine, drop-as-failure semantics, + serialized half-open probes. +- `src/plugins/audit/sqlite.rs`: three-state lifecycle helpers + (`anchor_pending` / `promote_to_confirmed` / `promote_to_quarantined` + / `list_pending_older_than` / `list_quarantined`) for dual-anchor mode. +- `src/storage/rate_limit_mints.rs`: `MintRateLimiter` enforcing + per-OmniAccount mints/hour + per-OmniAccount EVM-tx daily budget. +- `solidity/src/AgentKeysAudit.sol`: append-only audit log contract + with indexed `recordHash` + `omniAccount` + `wallet` event topics. + +### What you do as an operator (deploy + go-live) + +#### 1.

Fund the fee-payer wallet + +The broker submits one transaction per mint to the audit contract — +each tx costs gas. Fund the fee-payer wallet on Base Sepolia (use the +public faucet at ). + +`BROKER_EVM_FEE_PAYER_MIN_BALANCE` (default 0.001 ETH) is the +threshold below which the EVM anchor flips to `Unready` — set to a +value that gives you ~30 min of mint capacity at peak. + +#### 3.

Live alloy integration (V0.1-FOLLOWUPS Phase E hardening) + +The current build registers `EvmStubAnchor` for the `evm_testnet` +audit anchor selection — it simulates round-trip behavior without +network I/O. The alloy-driven `EvmAuditAnchor` (live transaction +submission, receipt polling, log topic verification) lands as a Phase +E hardening pass. Until then, the structural layer (three-state +lifecycle, breaker, gas-drain) ships with the stub. + +### Gas-drain mitigations (US-034) + +Even with the explicit grant boundary, an attacker who steals a +session JWT could try to amplify mints into draining the fee-payer. +Three layers of defense: + +1. **Per-OmniAccount mints/hour** (`BROKER_RATE_LIMIT_MINTS_PER_HOUR_PER_OMNI`, + default 30): enforced via `MintRateLimiter::check_mint`.

The broker today exposes 6 routes: `/healthz`, `/readyz`, `/v1/mint-aws-creds`, `/.well-known/openid-configuration`, `/.well-known/jwks.json`, `/v1/mint-oidc-jwt`. Auth is a bearer token validated by an HTTP call to `BROKER_BACKEND_URL/session/validate`. Audit is local SQLite. Wallet provisioning, user-identity verification, and chain anchoring are all implicit / external today. + +Issue #64 asks for the **three layers** below the credential mint to become pluggable, behind Rust traits + feature gates, so that: + +1. **Auth layer** (who is the user?) is selectable: `WalletSig` (SIWE-wrapped EIP-191), `EmailLink` (passwordless magic-link), `OAuth2/Google` (id_token + PKCE), and v1+ extensions (additional OAuth providers, Passkey, TeePasskey). +2. **Wallet provisioning layer** (what wallet does this user own?) is selectable: `ClientSideKeystore` (BIP-39 in OS keychain, broker only sees address), and v1.5+ extensions (SmartContractAa, HeimaTee, AwsNitro). +3. **Audit layer** (where does the immutable record go?) is selectable: `Sqlite` (default), `EvmTestnet` (Base Sepolia for v0.1 testnet target), and v1+ extensions (Solana, HeimaParachain, S3 Object Lock). + +A sibling branch `claude/quizzical-ellis-d6f1e9` carries 6 codex review rounds of prior work on this idea — full plugins/ scaffold, Solidity AgentKeysAudit contract on Base Sepolia, dual-write circuit breaker, OmniAccount derivation, storage schema. It is **prior art**, not the implementation path: the user has chosen to start fresh with stricter process rules, harvesting only what survives review. + +**Goal:** ship a v0 broker that is production-ready on testnet — Base Sepolia for chain anchor, real SES email, real wallet-sig auth, real recovery — under explicit process discipline. + +**Non-goals:** Heima TEE integration, mainnet anchoring, smart-contract-AA wallets. These are v1.5/v2. + +--- + +## 1. The 11 process rules — pinned + +Every section below is governed by these rules. Numbering matches the user's brief: + +1. **E2E integration test on day 1.** `harness/stage-7-e2e.sh` exists and passes on the very first slice, before any individual layer is "deepened". +2. **Slice through all layers before deepening any.** Phase 0 (Day 1) ships the thinnest vertical slice that exercises the load-bearing invariant end-to-end. Subsequent phases deepen one layer at a time. +3. **Operator deploy doc is P0.** `docs/operator-runbook-stage7.md` is acceptance-gated by `harness/stage-7-done.sh` — not a Phase F polish task. +4. **No silent fallbacks. Default = refuse-to-boot.** Every plug-in choice, every env var, every credential source is explicit. If something is missing or invalid, the broker exits non-zero with a single-line error pointing at the runbook anchor. +5. **Status endpoints reflect operational state.** `/readyz` returns 503 unless every loaded plugin has reported `ready` for its own dependencies (DB connection, RPC reachable, JWKS keypair on disk, SES sender verified, audit DB writable). No trait default returning `Ok`. +6. **Validate every env-var-derived value at boot.** Type, range, format, reachability where cheap. Already partial on main — extend to all new vars. +7. **The load-bearing invariant gets a regression test on day 1.** See §2. +8. **Trait-based pluggable architecture with feature gates.** Default Cargo build links only the v0 plugins. `--features evm-audit,email-link` opts in to extras. v0 deployments do not link Solana/Heima/WebAuthn crates. +9. **Codex stopping rule.** Two consecutive rounds returning only same-severity P2 findings → ship; remaining P2s become v0.1 follow-ups in a tracked file. +10. **Smoke script per stage / per phase.** `harness/stage-7-phaseN-smoke.sh` for each phase below. +11. **Centralize env var names.** New module `crates/agentkeys-broker-server/src/env.rs` is the **only** place `BROKER_*` strings are defined. All callers reference `env::BROKER_OIDC_ISSUER` constants. Doc, runbook, and tests reference the same constants via a generated table. + +--- + +## 2. The load-bearing invariant + Day-1 regression test + +**Invariant (one sentence):** +> *No credential leaves the broker process except via a flow where the caller has proven control of an authenticated identity, that identity is bound to a wallet, that wallet has a valid grant for the requested resource, and an audit record naming all four (identity, wallet, resource, grant) has been durably persisted to **every** configured audit anchor before the credential is returned.* + +This is one invariant, not five. Breaking it anywhere — auth bypass, identity-to-wallet mismatch, missing grant, audit write that returned `Ok` without durability, audit write to anchor A but not anchor B — produces an unaudited credential release, which is the worst-class bug this system can have. + +**Day-1 regression test** (`crates/agentkeys-broker-server/tests/invariant_load_bearing.rs`): + +A single integration test that runs against an in-process broker stood up with the v0 plugin set + a `FailingAuditAnchor` test fixture. It asserts: + +- (a) Happy path: full WalletSig → keystore → mint → audit-write → response. SQLite row count goes 0 → 1, response returns AWS creds, and the row's `(identity, wallet, resource, grant_id)` matches the request. +- (b) Auth bypass attempt: tampered EIP-191 signature → 401, **zero** audit rows written, **zero** STS calls made. +- (c) Wrong-wallet attempt: valid sig for wallet A, request claims wallet B → 403, zero audit rows, zero STS. +- (d) Missing-grant attempt: valid identity + wallet, no grant for resource → 403, zero audit rows, zero STS. +- (e) **Audit-failure refuse-to-release** (load-bearing): valid auth+wallet+grant, but `FailingAuditAnchor::anchor()` returns `Err` → broker returns 500 *and the AWS credential is never returned in the response body*. STS may have been called speculatively, but the response must not leak. (Implementation note: speculative STS is acceptable; the gate is the audit write before the response is constructed.) +- (f) Dual-anchor partial-failure: when two anchors are configured (Sqlite + EvmTestnet) and one fails after the other succeeds → policy is `dual_strict`: response 500, no leak, but the SQLite row is logged as `quarantined` so a reconciliation job can either retry the EVM anchor or roll the SQLite row to `failed`. Test verifies (i) no creds returned, (ii) SQLite row marked quarantined, (iii) `/readyz` flips to `degraded` in subsequent calls. + +This test is checked in on Day 1 and runs in CI for every commit thereafter.

We use `sub` as the OmniAccount input. Email is stored in `identity_links` if present, useful for recovery and human-readable display. +- **Session JWT to CLI polling, never to browser** — same security posture as email-link (§3.5.3). +- **Provider abstraction** — `BROKER_OAUTH2_PROVIDERS=google` for v0; the trait shape supports `github` and `apple` as additional plug-ins behind their own Cargo features (each has provider-specific quirks: GitHub returns no id_token, Apple uses form_post response_mode). +- **Single-tenant client_id** — broker holds the OAuth client credentials; multi-tenant (each operator brings their own Google project) is a v1.5 question. + +Operator setup: register an OAuth2 web app in Google Cloud Console, add `https:///auth/oauth2/callback` as an authorized redirect URI, set `BROKER_OAUTH2_GOOGLE_CLIENT_ID` and `BROKER_OAUTH2_GOOGLE_CLIENT_SECRET_FILE` env vars.

Phases + +### Phase 0 — Day 1 vertical slice (target: 1–2 days) + +**Deliverables (all land in one PR):** + +- `src/env.rs` — every `BROKER_*` constant, with type + validation rules, exposed as a `Validated` struct + a `print_table()` for the runbook generator. +- Trait definitions in `src/plugins/{auth,wallet,audit}.rs` + `mod.rs` registering them. **No plug-in implementations beyond the bare minimum to compile.** +- One auth plugin: `WalletSig` — **SIWE-wrapped EIP-191** (§3.5.1), k256 ecrecover, single-use nonce table + 45-min issued_at/expiration_time window, domain binding via SIWE `domain` field. +- One wallet plugin: `ClientSideKeystore` (broker only stores `(omni_account, wallet_address, created_at, role)` rows; address binding inferred from the SIWE message — no separate "bind" sig needed because SIWE already proves control). +- One audit plugin: `SqliteAnchor` (port today's `audit.rs` to the trait shape, no behavior change). +- One **first-class capability grant layer** (§3.5.5): `POST /v1/grant/create`, `POST /v1/grant/revoke`, `GET /v1/grant/list`, with `audit_proof` (broker ES256 sig over canonical grant content) — this is what makes `revoke` truly instant. +- New HTTP endpoints: `POST /v1/auth/wallet/start` + `POST /v1/auth/wallet/verify` (returns session JWT, §3.5.1). +- Backward-compat shim: `POST /v1/auth/exchange` (§3.5.7) — accepts the legacy backend-validated bearer once, returns the new session JWT. Daemon/CLI calls it once at startup. No dual-accept on `/v1/mint-aws-creds`. +- `POST /v1/mint-aws-creds` upgraded: accepts session JWT only, requires per-call daemon signature (§3.5.2) over `(timestamp, body_hash, intent)`. Resolves the active grant for `(omni_account, agent_id, service)`, atomically increments `used_count`, returns creds + audit_record_id. +- Two ES256 keypairs (§3.5.6): existing `oidc_keypair` + new `session_keypair`. Purpose-tagged on disk; load-time validation refuses to boot on mismatch. +- `src/handlers/broker_status.rs` — `/readyz` aggregates plugin readiness (DB writable, JWKS keypair loaded, every plugin's `ready()`). +- `harness/stage-7-phase0-smoke.sh` — boot broker, run a curl-driven challenge → verify → mint flow against a fixture wallet, assert audit row, assert `/readyz==200`. +- `crates/agentkeys-broker-server/tests/invariant_load_bearing.rs` — the §2 test, all six cases. +- `docs/operator-runbook-stage7.md` — **draft** version of the deploy doc, with all env-var names referenced from `env.rs` (no copy-paste). +- `harness/stage-7-done.sh` skeleton — initially asserts only that Phase 0 deliverables exist; phases B–F append their assertions. + +**Why this slice:** it exercises auth → wallet → mint → audit on the actual prod path, with both refuse-to-boot config validation and audit-gated release tested. Every later phase deepens, never re-architects. + +**Acceptance:** `cargo test -p agentkeys-broker-server --features auth-wallet-sig` passes; `bash harness/stage-7-phase0-smoke.sh` exits 0; the load-bearing invariant test is green. + +### Phase A — Auth deepening: EmailLink + OAuth2 (Google) (2–3 weeks) + +Add two plug-ins. Both share the **polling-based browser-to-CLI session JWT delivery** pattern (§3.5.3 / §3.5.4): the browser never sees the session JWT, only a "Verified — return to your terminal" page; the CLI gets the JWT via a `GET /v1/auth//status/{request_id}` poll. This consistency reduces the cognitive load on developers and shares ~70% of the implementation between the two methods. + +#### A.1 — EmailLink (`auth-email-link` feature) + +Wire format fully specified in §3.5.3 — **not deferred** (Codex P0 #3, Designer #1). + +- Endpoints (§3.5.3): + - `POST /v1/auth/email/request` — mails a fragment-token magic link via existing SES. + - `POST /v1/auth/email/verify` — consumes the token (POST body, never URL query) and stores the verification result keyed by `request_id`. + - `GET /v1/auth/email/status/{request_id}` — CLI polling endpoint that returns `{status: pending|verified, session_jwt?}`. + - `GET /auth/email/landing` — broker-hosted static HTML page (no JS framework, ~30 lines) that reads `window.location.hash`, POSTs to `/verify`, and shows "Verified — return to your terminal." Headers: `Cache-Control: no-store`, `Referrer-Policy: no-referrer`. +- Token format: 32 bytes from CSPRNG, base64url-encoded, stored in `email_tokens` with UNIQUE constraint on the token hash (we store `SHA256(token)`, not the token, so DB exfil doesn't yield usable tokens). +- Single-use enforcement: race-safe `UPDATE email_tokens SET consumed_at=now WHERE token_hash=? AND consumed_at IS NULL` — exactly one writer wins. +- Rate limits (Codex P1 #5): per-email per-hour bucket + per-source-IP per-minute bucket, both configurable via `BROKER_EMAIL_RATE_LIMIT_*` env vars; refuse-to-boot if config nonsensical. +- HMAC key (`BROKER_EMAIL_HMAC_KEY_PATH`): 32-byte file. We HMAC the token row's primary key into the audit log so audit trail entries can be verified post-hoc without reading the raw token. +- Prefetch resistance: tokens are consumed only on POST. Email clients that prefetch GET URLs see the static landing page (which is harmless). Codex P0 #3 → closed. +- `Readiness` checks: SES sender identity verified (cached 5 min, persisted to disk so restart-loops don't burn SES API budget — Codex P2 #8), HMAC key file readable, rate-limit table writable. +- Smoke: `harness/stage-7-phaseA-smoke.sh` (email portion) — full flow against `--features test-stub` SES driver, plus a curl assertion that the verify endpoint refuses GET (returns 405). + +#### A.2 — OAuth2 / Google (`auth-oauth2-google` feature) + +Wire format in §3.5.4 — standard OAuth2 + OIDC + PKCE + state-CSRF, with session-JWT delivery via the same polling endpoint shape as A.1. + +- Endpoints (§3.5.4): + - `POST /v1/auth/oauth2/start` — returns `authorization_url` + `request_id` + `poll_url`. Broker mints PKCE verifier + HMAC-signed `state` (binds request_id) and persists in `oauth_pending` table. + - `GET /auth/oauth2/callback` — Google's redirect target. Verifies state HMAC, looks up PKCE verifier, server-side exchanges code for id_token at `https://oauth2.googleapis.com/token` (5s timeout). Verifies id_token via cached JWKS (TTL 1h). Mints session JWT, stores keyed by request_id, renders minimal HTML. + - `GET /v1/auth/oauth2/status/{request_id}` — CLI polling endpoint, returns `{status: pending | verified | failed, session_jwt?, reason?}`. +- Identity binding: `omni_account = SHA256("agentkeys" || "google" || google_sub)`. Email (if returned by Google) saved in `identity_links` for recovery + display, never as the OmniAccount input. Email migration (Workspace move) does not change the OmniAccount. +- Defenses: + - PKCE mandatory (defense in depth — code interception → still need verifier). + - State HMAC ties browser callback to originating CLI session — prevents CSRF. + - `prompt=select_account` — defends against silent wrong-account auth when user has multiple Google accounts in the browser. + - JWKS fetch with cached pubkey, refresh on `kid` miss; refuse to verify on JWKS fetch failure (no soft-fail). + - id_token: verify `iss="https://accounts.google.com"`, `aud=our_client_id`, `exp > now`, `iat` skew ≤ 60s, `nonce` matches request-bound nonce. + - `oauth_pending` row TTL 10 min; consumed on first callback success. +- Rate limit: per-IP-minute on `/auth/oauth2/start` (configurable `BROKER_OAUTH2_START_RATE_LIMIT_PER_IP_MINUTELY`, default 30/min). +- `Readiness` for OAuth2 plugin checks: client_id + client_secret loaded; JWKS fetch succeeded ≥ once in last hour (cached); `oauth_pending` table writable. +- Operator setup (Phase E runbook §oauth2-setup): create OAuth client in Google Cloud Console, register redirect URI `https:///auth/oauth2/callback`, set `BROKER_OAUTH2_GOOGLE_CLIENT_ID` + `BROKER_OAUTH2_GOOGLE_CLIENT_SECRET_FILE`. Validate by running `curl https://broker/v1/auth/oauth2/start -d '{"provider":"google"}'` and opening the returned URL. +- Smoke: `harness/stage-7-phaseA-smoke.sh` (oauth portion) — `--features test-stub` mocks Google's token + JWKS endpoints; flow asserts state CSRF rejection (mutated state → 400), PKCE verifier required (missing verifier on stubbed token endpoint → 401), id_token expired → 401, happy path → session JWT. + +**Acceptance:** cargo test green with `--features auth-wallet-sig,auth-email-link,auth-oauth2-google`; `bash harness/stage-7-phaseA-smoke.sh` exits 0; manual test against real Google OAuth in a dev project (one-time per operator); manual test confirms an email link prefetched by `curl -L` does NOT consume the token. + +### Phase B — Capability grants + wallet recovery (1.5 weeks) + +Two deliverables in one phase: + +**B.1 Capability grants (Codex P0 #4 mitigation, port-vs-greenfield "first-class data"):** +- Endpoints (§3.5.5): `POST /v1/grant/create`, `POST /v1/grant/revoke`, `GET /v1/grant/list`. +- Storage: `grants(grant_id ULID PK, master_omni_account, daemon_address, scope_json, granted_at, expires_at, max_uses, used_count, revoked_at, audit_proof BLOB)`. +- `audit_proof` = broker session-keypair ES256 signature over canonical CBOR of the grant content. Means a tampered grant row in an exfiltrated DB fails verification — DB exfil ≠ unauthorized mint. +- Mint flow now resolves the active grant atomically (`SELECT … FOR UPDATE`-equivalent via SQLite immediate transaction) and increments `used_count`. Revoke is one row update; instant. + +**B.2 Recovery — master-gated, never email-only (Codex P0 #4):** +- New table: `identity_links(omni_account, identity_type, identity_value, linked_at)`. +- New endpoint: `POST /v1/wallet/link` (auth: master session JWT). +- Recovery is **not** "fresh-auth-from-any-linked-identity → re-bind." That model lets a phished email become wallet takeover. Instead, recovery is **a new capability grant** signed by an existing master: + - The recovering daemon authenticates with whatever identity it has (email or fresh wallet-sig). + - It cannot mint anything until the master issues a `POST /v1/grant/create` for the new daemon address. The master signs a session JWT challenge from their existing trusted device. + - Optional time-locked grant: `BROKER_RECOVERY_GRANT_DELAY_SECONDS` enforces a configurable cooldown before a recovery grant becomes active, with a notification (email to all linked identities) — defends against compromised-master scenarios. +- For v0 testnet, time-locked recovery is feature-flagged off by default; operators can enable. Decision-sheet item. +- Smoke: `harness/stage-7-phaseB-smoke.sh` — pair → link email → revoke daemon → spin new daemon → master issues recovery grant → new daemon mints → assert grants for old daemon are independent (revoking old grant doesn't revoke new one, and vice versa). + +**Acceptance:** grant + recovery smokes green; cargo test green; audit_proof verification rejects tampered grant rows. + +### Phase C — Chain audit anchor (testnet) (2 weeks) + +Add `EvmTestnetAnchor` behind `audit-evm` feature. Target: **Base Sepolia** (cheap, fast, public, no Litentry coordination — matches sibling branch's choice). + +Components: +- Reuse the sibling branch's `AgentKeysAudit.sol` contract design (foundry, indexed `recordHash`, indexed `omni_account`, indexed `wallet`). Re-deploy fresh from this branch, recorded in `crates/agentkeys-broker-server/solidity/deployments/base-sepolia.json`. +- Rust: `alloy-provider` + `alloy-signer-local` for tx submission. Fee payer is a new env var: `BROKER_EVM_FEE_PAYER_KEYSTORE` (path to encrypted keystore JSON, refuse-to-boot if missing or unreadable). +- **Three-state write protocol** (Eng review #data-flow): SQLite row inserted as `pending` first, then EVM tx submitted, then SQLite promoted to `confirmed` only after receipt. EVM-failure → SQLite to `quarantined`. Crash between SQLite-pending and EVM submit → reconciler picks up `pending` rows on restart. Closes the eng-review-flagged hole where `confirmed` could be set without an EVM anchor. +- Multi-anchor write: when both `sqlite` and `evm_testnet` are configured, `dual_strict` policy gates the response on EVM receipt. Failure → response 500, SQLite row marked `quarantined`. The `pending`/`quarantined`/`confirmed` lifecycle is the canonical state machine. +- Reconciliation job (long-running tokio task with a `CancellationToken`): rescans `pending` rows older than 30s + `quarantined` rows every N seconds and retries the failing anchor. Joins on shutdown — drops the in-flight tx never; either it lands or it's logged as orphaned for operator-side cleanup. Closes Eng review's reconciler-shutdown hole. +- Circuit breaker on EVM anchor: open after K consecutive failures, half-open every M seconds. `/readyz` reports `degraded` when EVM circuit is open and `BROKER_AUDIT_POLICY=dual_strict` (mints serve 500s). +- **Gas-drain mitigations** (Codex P0 #7 + P1 #5): cannot rely solely on circuit breaker — that's the *failure mode*, not mitigation. Add three layers: + 1. **Per-identity sliding-window rate limit** on auth-challenge AND mint endpoints, configurable via `BROKER_RATE_LIMIT_*`. Default: 30 mints/hour per `omni_account`, 60 challenges/hour per IP. + 2. **Per-identity daily EVM-tx budget** — `BROKER_EVM_PER_IDENTITY_DAILY_TX_BUDGET` (default 100). When exceeded, the identity's mints serve 429 until budget resets at 00:00 UTC. Per-identity counter table. + 3. **Fee-payer balance floor** — `BROKER_EVM_FEE_PAYER_MIN_BALANCE`. Below this, EVM anchor flips to `Unready` immediately (not after circuit-breaker opens). Boot-to-Unready (Tier 2 in §6) checks this on startup; runtime check on every tx submit. +- Replay-receipt verification on reconciliation: `verify()` re-fetches the receipt from RPC and confirms the tx hash + block number + log topics still match (handles shallow Base Sepolia reorgs — Eng review #edge-cases). +- Smoke: `harness/stage-7-phaseC-smoke.sh` — boot with both anchors, mint creds, assert SQLite row goes `pending → confirmed` + on-chain event visible. Kill the RPC, mint again, assert 500 + `quarantined` row + `/readyz` degraded. Drain the fee-payer below floor, assert mint serves 503 + `/readyz` Unready (not 500). + +**Acceptance:** Phase 0 invariant test now runs in dual-anchor mode and stays green; chain-anchor smoke green; reconciliation job verified by integration test. + +### Phase D — Production hardening (1 week) + +- Graceful shutdown: SIGTERM → drain in-flight requests up to `BROKER_SHUTDOWN_GRACE_SECONDS` → exit. Existing config has the var; wire it through Axum. +- Observability: structured JSON logs (already on `tracing-subscriber`), `prometheus` exporter at `/metrics` behind `BROKER_METRICS_ENABLED=true`. Counters for: mints, mints_failed, audit_writes, audit_writes_failed, auth_attempts, auth_failed_by_reason. Histograms for: mint latency, audit-write latency. +- Migration discipline: `migrations/0001_v2_schema.sql` (port the sibling branch's schema, audited). Migrations run at boot, refuse-to-boot if migration fails. +- Idempotency on mint: optional `Idempotency-Key` header dedupes within a 5-minute window — if same key + same body → return cached response; if same key + different body → 422. +- Smoke: `harness/stage-7-phaseD-smoke.sh` — kill -TERM during a slow mint, verify clean shutdown, verify metrics are exposed and increment correctly. + +**Acceptance:** chaos tests for graceful shutdown + metric increments green; cargo test green. + +### Phase E — Operator deploy doc completion (1 week, runs partially in parallel with C+D) + +- `docs/operator-runbook-stage7.md` — finalized version. Sections: prerequisites, env-var table (auto-generated from `env.rs`), TLS termination, OIDC issuer DNS, AWS IAM trust policy + role + provider creation, EVM keypair funding on Base Sepolia, SES domain verification, smoke validation, rollback steps, troubleshooting (top 8 errors with cause → fix → docs link, mirroring CEO plan §"Error message spec"). +- `docs/operator-runbook-stage7-quickstart.md` — 10-minute setup for a single-operator testnet deploy. +- `harness/stage-7-done.sh` final form: greps each P0 doc section title; greps each `BROKER_*` constant from `env.rs` against the runbook env-var table (catches drift); runs every phase smoke script; runs the load-bearing invariant test. + +**Acceptance:** `bash harness/stage-7-done.sh` exits 0 with no skips. + +### Phase F — Codex review loop, ship-or-roll (until stop rule fires) + +Per rule 9: run codex review in rounds.

Refuse-to-boot rules — tiered + +Codex P1 #6 flagged that lumping config validation with external-reachability creates an outage trap (transient DNS / SES throttle / RPC hiccup → broker bricked in restart loop). We split into two tiers: + +### Tier 1 — Refuse-to-boot (synchronous, before binding the listener) + +These are config-correctness checks. No network. If anything fails the broker exits non-zero: + +- All required env vars present and non-empty. +- Type/range/format: ints in declared bounds, paths exist or can be created, URLs parse, OIDC issuer is `https://` in non-dev mode (a `BROKER_DEV_MODE=true` flag relaxes this single rule and is logged loudly at startup). +- File-on-disk readability: both ES256 keypair files present + parseable + purpose-tagged correctly (§3.5.5); HMAC key file present + ≥ 32 bytes; EVM keystore JSON parses and decrypts with the password file. +- Plugin compile-time presence: every name in `BROKER_AUTH_METHODS / BROKER_AUDIT_ANCHORS / BROKER_WALLET_PROVISIONER` is registered in the runtime registry. +- SQLite migration runs cleanly (this is local I/O — counts as Tier 1). +- All-or-nothing keypair setup: if any keypair path is absent, refuse-to-boot with explicit `agentkeys-broker-server keygen --purpose oidc --out PATH` and `--purpose session --out PATH` instructions. **No silent generation.** (Today's `oidc.rs:113` silently generates — fix in Phase 0.) + +Failure → exit code 1, single-line stderr: `BOOT_FAIL: =: ; see runbook §`. + +### Tier 2 — Boot-to-Unready (async, after listener is bound) + +External-reachability checks that mark the broker `Unready` until they pass. Broker still binds the port and serves `/healthz` (200) + `/readyz` (503 with structured detail). This lets the operator observe logs/metrics during transient outages instead of being stuck in a restart loop: + +- Backend `/healthz` reachable. +- SES sender identity verified — when email-link enabled. **Persisted cache** under `$BROKER_DATA_DIR/ses-verify.json` survives restart, with a 24h TTL so debugging-restarts don't re-burn the SES API budget. +- EVM RPC `eth_chainId` returns the configured `BROKER_EVM_CHAIN_ID` — when audit-evm enabled. +- EVM fee-payer balance ≥ `BROKER_EVM_FEE_PAYER_MIN_BALANCE` — when audit-evm enabled. + +Each Tier 2 check has its own `Readiness` entry in `/readyz` JSON. The operator runbook documents which checks block which features (e.g., "email-link auth requires SES check; mints with `dual_strict` policy require EVM RPC + fee-payer balance"). + +The `BROKER_REFUSE_TO_BOOT_STRICT=true` env var collapses Tier 2 into Tier 1 (every reachability check becomes a hard boot fail) for environments that prefer fail-loud over fail-degraded. Off by default. + +--- + +## 7. Status endpoint behavior + +`/healthz` — process up, returns 200 always (excluding panics). + +`/readyz` — aggregates `Readiness` from every loaded plugin + `BrokerConfig::live_check()`: + +| Plugin / check | `Ready` when … | `Degraded` when … | `Unready` when … | +|---|---|---|---| +| WalletSig | nonce table writable | — | DB unreachable | +| EmailLink | SES sender verified ≤ 5 min ago, HMAC key loaded | SES status stale (>5 min) | SES API error or HMAC missing | +| OAuth2/Google | client_id + client_secret loaded, JWKS fetch ≤ 1h ago, oauth_pending writable | JWKS stale (>1h, last fetch failed) | JWKS unfetchable or client_secret missing | +| ClientSideKeystore | wallets table writable | — | DB unreachable | +| SqliteAnchor | DB writable | — | DB unreachable | +| EvmTestnetAnchor | RPC reachable, circuit closed, fee-payer keystore unlocked | circuit half-open, RPC slow | circuit open or fee-payer locked | +| OIDC keypair | loaded, kid stable | — | not loaded | +| Backend session/validate | reachable | slow > 1s | unreachable | + +Any `Unready` → 503.

Kept here for traceability, not for action: + +- A1 (auth surface): now Phase 0 ships SIWE-wrapped wallet-sig; EmailLink Phase A. Resolved. +- A2 (magic link vs OTP): magic link with fragment-token wire (§3.5.3).

Resolved. +- B1 (wallet provisioner): `ClientSideKeystore` only for v0.

Carried forward. +- C2 (audit policy): `dual_strict` default. **Open** — decision sheet item (does the user want to ship `dual_strict` or `sqlite_primary` while EVM anchor stabilizes?). +- C3 (fee-payer key): keystore + password file. Carried forward. +- D1 (codex stop rule): now requires independent prompt + user sign-off on residual P2s (Codex review #10). **Open** — decision sheet item. +- D2 (phase ordering): now Phase 0 → A → C.0 (graceful shutdown + migrations, lifted from D) → B → C → D-rest → E. **Open** — decision sheet item. +- D3 (production-ready definition): reframed in decision sheet. +- D4 (plan home): `docs/spec/plans/issue-64/`.

Resolved. + +--- + +## 14. Why this plan (rather than the sibling branch) + +The sibling branch shipped substantial work but does not visibly satisfy several of the user's explicit rules: + +- The sibling branch's broker-status / readyz handling on first inspection looks present but is not gated by every plugin's `Readiness` (§5). +- No visible centralized `env.rs` — env-var strings appear inline at multiple call sites. +- No visible Day-1 load-bearing invariant test — the test files exist for individual flows but not for the single composed invariant. +- Codex round 6 found a P2 in audit indexing (legit, valuable) but rounds 1–6 were not gated by the §9 stop rule, so the work spread without a hard stopping criterion. + +This plan inherits the **artifacts** that survive review (Solidity contract, dual-write breaker, schema) and re-imposes the rule discipline at the structure level. Net delta is small in code, large in process clarity. + +--- + +## 15.

For wallet-sig the `identity_value` is the raw wallet address. The asymmetry could surprise callers expecting `identity_value` to be the email itself.

Any downstream code that asserts a non-empty wallet (e.g., `mint_v2` per-call sig verification) will reject these JWTs — which is correct in v0 (email-only users can't mint AWS creds without first binding a wallet via Phase B), but the failure mode is silent and confusing. + +**Mitigation cost.** Either reject session-JWT mint at the email-verify path with a clearer "bind a wallet via Phase B first" error, OR document the email-only-identity limit in the runbook.

That contradicts the Phase B contract in `GrantStore::try_consume`'s own comment, which says `NoGrant / Revoked / Expired / Exhausted` all map to 403 at `grants.rs:243`, and breaks the plan §3.5.5 client error-handling contract.

Other endpoints (`/v1/auth/wallet/start`, `/v1/auth/wallet/verify`, `/v1/auth/exchange`) accept JSON bodies and have the same exposure. +3. axum's default body limit IS active (2 MB by default per axum 0.7) — so the practical exposure is "an attacker can POST up to 2 MB" not "an attacker can POST gigabytes." +4. The env var `BROKER_REQUEST_BODY_LIMIT_BYTES` exists; wiring it to `DefaultBodyLimit::max` is a one-line follow-up. + +Net: documented memory bound is 2 MB, exploitation cost is non-negligible (CPU during JSON parse), no credential exposure, no audit log corruption.

Requires orchestrator streaming-API refactor. 5b. -3. Phantom chaos test emits `{code:"store_failed"}` instead of a dedicated `verification_failed` code. Add `ProvisionErrorCode::VerificationFailed` variant and wire through in 5b. -4. US-009 uses hand-crafted HTML via `page.route()+route.fulfill()` instead of a literal `.har` file.

This commit: - DEPLOYS signer.litentry.org as an independent backend listener (issue #74 step 1b). agentkeys-mock-server gains a `--signer-only` mode that registers ONLY `/dev/derive-address`, `/dev/sign-message`, `/healthz` (no legacy session/ credential/audit endpoints). Bound to 127.0.0.1:8092; nginx fronts it at https://signer. with its own cert. Same binary, two roles — loopback :8090 stays as the broker's tier-2 reachability target. - ADDS JWT bearer verification to /dev/* handlers. The signer reads the broker's ES256 session pubkey at boot from a pinned file (/var/lib/agentkeys/.agentkeys/broker/session-keypair.pub.pem) written by the broker's new --export-session-pubkey-to flag. Every /dev/* request must carry Authorization: Bearer with claims.agentkeys.omni_account matching body.omni_account; otherwise 401 unauthorized. No SIGNER_ACCESS_TOKEN. No HMAC. No device-key signing — those land in step 1c. - PLUMBS the JWT through the daemon-side stack: HttpSignerClient gains with_session_jwt(); CLI signer/whoami commands load the saved session and set the bearer; init_flow returns the EVM session JWT for the caller to persist. - AUTOMATES setup-broker-host.sh to provision the new agentkeys-signer.service systemd unit and the nginx server block for signer.. Idempotent — re-runs preserve the master secret + session pubkey + nginx config. PLAN DOCS: - docs/spec/plans/issue-74-step-1c-device-key-auth.md (NEW, 381 lines) Replaces broker-issued bearer JWT as the sole authenticator on /dev/* with a device-key signature scheme. Removes broker-as-SPOF risk for the signer call surface; identity-type-uniform across evm/email/oauth2/ passkey; UX-uniform (one ceremony at init, automatic per-request). Aligned with Heima's ClientAuth tier model (EvmSiweSigned + BackendSigned), strictly stronger because user-controlled per-request key + zero per-request user interaction. See gh issue #76. - docs/spec/architecture.md (REWRITTEN, 506 lines, replaces prior version) Canonical broker/signer/daemon/key-flow doc. Mermaid diagrams for component map, trust boundaries, identity model, init sequence, per-mint sequence, deployment topology. Full K1–K10 key inventory table designed for direct Figma reuse. Pluggable-surfaces matrix covering auth methods, signer backends, audit destinations, vault backends. stage7-wip.md absorbed into §1, §6, §7, §11; archived. - docs/spec/heima-gaps-vs-desired-architecture.md (REVISED) Added §1a status snapshot table covering all 12 gaps at-a-glance. §3 OIDC provider + §6 PrincipalTag JWT claim marked RESOLVED IN-TREE (post-PR #61 + #73). NEW §11 (signer-edge contract — PARTIAL after PR #75) and §12 (per-request crypto auth — PLANNED via #76). Resolution log under §10. - docs/stage7-demo-and-verification.md (UPDATED for the signer split) Drops the SSH tunnel scaffolding entirely. Single demo path uses the public signer hostname. Trust-model diagram + two-machine layout + §0.2 reach-the-signer + §14.3 troubleshooting + §16.4 live walkthrough + §16.7 auto-provision + §17 cleanup all updated. VERIFICATION: - 394 tests pass workspace-wide (was 386 in PR #75; +8 new JWT auth integration tests in dev_key_service_routes.rs). - 0 cargo clippy errors; 18 pre-existing warnings (was 16; +2 minor cosmetic in agent-generated test code). WHAT DID NOT LAND: - Live broker host redeploy + signer. certbot issuance — operator step. The script that makes it work shipped here. To land: ssh broker host → bash scripts/setup-broker-host.sh --yes → sudo certbot --nginx -d signer. → smoke per docs/stage7-demo- and-verification.md §16. - Device-key auth (issue #74 step 1c) — separate issue #76, plan doc shipped in this commit. Co-Authored-By: Claude Opus 4.7 (1M context) * docs: address review-questions Q1-Q8 (PoP, cold-start ordering, per-identity-type processes, K9 explanation) Addresses /Users/agent-jojo/.claude/plans/review-questions.md Q3 (K9 DKIM explanation): expanded the K9 row in architecture.md key inventory with a high-level "what is DKIM, why does AgentKeys need it" paragraph (per-domain Ed25519 key, signs outbound mail headers, pubkey in DNS TXT, used by Stage 6 federated email so SES never sees plaintext). Q5 (cold-start sequence ordering): rewrote architecture.md §5 to show device key generated FIRST (step 0), BEFORE the identity ceremony. The ceremony then binds D_pub atomically. Same trust shape as a WebAuthn credential creation — by the time the broker mints session JWTs, the device-pubkey claim is authoritative. Q6 (per-identity-type processes): NEW architecture.md §5a covers init-binding for each identity type (email-link, oauth2_google, evm, passkey, sandbox link-code), device-switching when operator gets a new laptop, intentional device-key rotation with chain-of-custody sigs, sandbox VM device-key persistence, and a trust-shape comparison across identity types. Architecture.md is now the single source of truth; step-1c plan defers to it. Q7 (init binding security — proof of possession): updated step-1c plan §"email" to require a `pop_sig` over the request payload signed by D_priv. Broker rejects with 400 bad_pop on mismatch. Closes the "attacker substitutes pubkey at request time" attack: attacker would need to compromise BOTH the network path AND the user's email inbox (vs just the network today). Q8 (sandbox VM device-key persistence): resolved via architecture.md §5a.4. Stock agent-infra/sandbox falls back to keyring-rs file backend under ~/.agentkeys/daemon-/session.json (mode 0600); survives daemon restarts inside long-lived containers; vanishes with ephemeral sandbox containers. For ephemeral sandboxes, operator runs `agentkeys-daemon --init-link-code ` per session — same pattern as today's pair-flow. Q1 (forward-references): - issue-74-dev-key-service-plan.md gains a "Status (post-PR #75) — successor steps" preamble pointing at step 1b + step 1c as the follow-on work. - stage7-demo-and-verification.md trust-model section gains a callout that step 1c will upgrade /dev/* auth from bearer-JWT to device-key per-request signature; the demo flow shape doesn't change. Q2 (cleanup + placement): filed as issue #77 (separate from this commit). Tracks (a) the legacy mock-server endpoint cleanup after #75 + #76, and (b) the open question of where identity/audit endpoints belong long-term — captures the user's broker-policy / signer-execution split proposal. Q4 (storage location — answered inline, no doc edit): omni ↔ identity linking is stored in the broker at crates/agentkeys-broker-server/src/storage/identity_links.rs (SQLite table `identity_links`, indexed on (identity_type, identity_value)). Co-Authored-By: Claude Opus 4.7 (1M context) * docs: cleanup pass on review-questions edits (renumber, PoP consistency, stale refs) Three structural cleanups across the 5 docs touched in commit 6d36a7b: 1. heima-gaps-vs-desired-architecture.md — section ordering fix. Previous numbering was 1, 1a, 2..9, 11, 12, 10 (Tracking out of order). Renumbered: §11 (NEW signer-edge contract) → §10 §12 (NEW per-request crypto auth) → §11 §10 (Tracking — was wedged between) → §12 Updated §1a status snapshot table accordingly. Updated 3 stale in-body §-refs: - §1a row 3: "architecture.md §11" → §7 (Pluggable surfaces) - §11 body "TEE swap-ready (gap §11)" → "(gap §10)" - §11 body "Blocks the TEE worker (gap §11)" → "(gap §10)" Updated tracking-section "PR #75 / issue #76 close §11 and queue §12" → "close §10 and queue §11"; resolution-log entries to match. 2. issue-74-step-1c-device-key-auth.md — PoP consistency across all identity types. Previously only the `email` flow had explicit proof-of-possession; `evm` and `oauth2_google` flows didn't. Same Q7 attack surface applies to all three, so: - `evm` flow: daemon now signs the SIWE binding payload with D_priv (in addition to the EVM key); broker verifies both signatures (proves "user owns EVM identity AND daemon controls device key"). - `oauth2_google` flow: daemon now signs the start request with D_priv; broker verifies before issuing any state value. Composes with the existing `state` parameter binding. 3. architecture.md — dropped "(preserved from prior architecture revision)" parenthetical from §9 Component inventory and §10 Language choices headings. Internal-changelog noise that doesn't help readers. Verification: 394 workspace tests pass, 0 fail. heima-gaps section ordering now sequential (1 → 1a → 2..9 → 10 → 11 → 12). All §-refs resolve to live anchors. step-1c PoP coverage confirmed in all three identity-type sections. Co-Authored-By: Claude Opus 4.7 (1M context) * docs: master/agent split + WebAuthn-uniform binding ceremony (v0.2 target) Architecturally collapses the four bespoke per-identity PoP shapes (email pop_sig, oauth2 pop_sig, evm dual-sign-SIWE, passkey) into two uniform binding ceremonies, split by machine class: - Master machines (workstation with platform authenticator) -> WebAuthn enrollment ceremony. Hardware-attested, identity-type- agnostic, closes the email-account-compromise -> device-takeover gap (Q7) by requiring hardware presence at re-bind. - Agent machines (VM/Linux/CI/agent-infra/sandbox container) -> link-code redeemed against master's authenticated session per the agent-infra/sandbox two-tier orchestrator pattern. Defers YubiKey-on-Linux-as-master (roaming-authenticator binding) to issue #79 as a follow-up. arch.md changes (single source of truth): - §2 trust boundaries: K11 in master TB, new agent-machine TB, master/agent rows in compromise table - §3 K-table: K10 master/agent persistence dichotomy; new K11 for WebAuthn platform-authenticator credential - §5 cold-start: status callout pointing at §5a.1 for v0.2 target - §5a header: master-vs-agent intro + WebAuthn-uniform status - §5a.1: rewrite into identity ceremonies + 5a.1.M (WebAuthn) + 5a.1.A (link-code) + v1c-interim PoP shapes pointer - §5a.2: master/agent device-switch shapes; cross-device confirmation note - §5a.3: WebAuthn get()-gated rotation for masters - §5a.4: agent persistence per agent-infra/sandbox; link-code-per- session is the right answer, not a workaround; cite 1-step- analysis.md - §5a.5: trust-shape table collapses to master/agent rows Plan files defer to arch.md as authoritative: - step-1c plan: status callout + per-identity-type section header marked v1c-interim - dev-key-service master plan: successor steps note WebAuthn binding + link to #79 Companion artifacts: - gh issue #79 filed (YubiKey-on-Linux master deferral) - comment on #76 with WebAuthn refinement summary * docs: arch.md — fix stage-0 device-key generation contradiction (§5 vs §5a.1.M) §5 cold-start sequenceDiagram correctly shows D generated at step 0 (before identity ceremony / network traffic). §5a.1.M had it as step 1 AFTER identity ceremony returns binding_nonce — internally inconsistent within arch.md. §5 is the right model: D should be generated at daemon startup, not deferred until identity ceremony completes. There is no security benefit to delaying, and D_pub must exist by the time of any binding ceremony anyway (v1c pop_sig signs identity request with D_priv; v0.2 WebAuthn challenge folds D_pub into the ceremony challenge). Changes: - §5a.1 intro: explicit three-stage pipeline. Stage 0 = device-key generation at daemon startup; Stage 1 = identity ceremony; Stage 2 = binding ceremony. State that stage 0 is non-negotiably first across all flows (master, agent, v1c, v0.2) with the reasoning. - §5a.1.M: drop the misleading "step 1: generate D_priv". Now opens with explicit PRECONDITIONS from stage 0 + stage 1, and binding- ceremony numbering starts at the WebAuthn step itself. Final step notes D_priv was already persisted at stage 0 (just persist J0). - §5a.1.A: agent flow's daemon-startup D-generation now explicitly labelled "Stage 0 (daemon startup, per §5a.1)" for symmetry. Numbering unchanged (cross-machine sequence continues from master). - §5a.2.M: new-master device-switch flow now leads with Stage 0 (fresh K10' generated at daemon startup) before identity ceremony, matching first-init. §5a.3.M rotation step "generate D_priv_new" is unchanged — that's an explicit new-key generation within the rotation flow, not first-time init, so stage-0 framing doesn't apply. * docs: arch.md §5a.1.M — fill J0 → J1 bridge gap referenced by §5a.1.A §5a.1.A's precondition expected J1_master (the EVM-omni session JWT) but §5a.1.M ended at J0 (the identity-omni JWT). The wallet-derive + link + SIWE round-trip that mints J1 lives in §5 steps 2-3 but was never referenced from §5a.1.M's outro, so the reader had no path between the master binding ceremony and the agent link-code flow. Changes: - §5a.1.M: new "From J0 to J1 (master only — bridge to per-mint flows)" subsection. 6-step flow: signer derive-address → broker wallet/link → broker auth/wallet/start → signer sign-message → broker auth/wallet/verify → mint J1. States that K10 + K11 claims propagate from J0 into J1 atomically. Notes the evm-identity-type variant collapses these steps (user's own EVM key IS the wallet). - §5a.1.A precondition: now reads "ON MASTER (already initialized per §5a.1.M + the J0 → J1 bridge above; holds J1_master = the long-lived EVM-omni session JWT with K10 + K11 claims)" — makes the dependency on the bridge explicit. * docs: adopt HDKD per-agent omni model + arch.md compaction (709 lines, -235) Adopts the per-agent omni model proposed by user critique: - Each agent is a first-class actor with its own omni derived from master via HDKD //label, its own wallet (HKDF(K3, O_agent)), its own AWS PrincipalTag, its own audit slot. - Per-agent compromise containment, atomic revocation, first-class audit attribution, tree-as-data-model. - v1c "shared omni + multiple device pubkeys" is now a degenerate v1.0 tree (no children). Plus the link-code-only-agent-bootstrap simplification: - Agents have ONE bootstrap path: link-code from authenticated master. - No identity ceremony for agents, no shared bearer, no agent-side recovery. One test surface, one threat model. arch.md changes (compacted 944 -> 709 lines): - §3 K3/K4: per-actor-omni derivation framing; K10/K11 references updated to new §5a subsection numbering - §4 identity model: HDKD actor tree (master root + //label children), per-actor wallet derivation, why per-agent omni - §4a NEW: 4-axis mental model (identity / actor / machine / capability), master-vs-agent role table, key non-conflations - §5 cold-start: compact 4-stage table + single sequenceDiagram showing v1.0 master flow with WebAuthn enrollment + bridge to J1; v1c interim status callout - §5a restructured into 5 subsections (was multi-subsubsection): - 5a.1 master init (per-identity-type + uniform WebAuthn binding) - 5a.2 agent bootstrap (link-code only - explicit "no other path") - 5a.3 master device switch + rotation (combined) - 5a.4 agent re-bootstrap + persistence (combined; cites 1-step-analysis.md) - 5a.5 trust shape (per-actor isolation properties) CLAUDE.md: added "Architecture-as-source-of-truth policy" requiring arch.md re-check after any architectural doc edit; documents that per-doc detail outgrowing arch.md should link outward, not duplicate. step-1c plan: status callout reframed - v0.2 target is HDKD per-agent omni + WebAuthn-uniform binding (structural shift, not just wire-shape collapse); points at arch.md §4/§4a/§5a as single source of truth. Companion artifacts (not in commit; reference only): - .omc/wiki/agent-role-and-usage-hdkd-per-agent-omni.md (project-local wiki page, gitignored per .omc/ convention) - gh issue #79 updated: master-vs-agent reframed as actor role, not machine class; YubiKey-on-Linux is "Linux + YubiKey as master" (one of two roles, not a third class). * docs(demo): align stage7 demo doc with new architecture vocabulary Updates the operator-facing demo doc for the master/agent + HDKD mental model landed in the prior commit (50a0ffa). Operational content (steps 0-13) is unchanged because the demo runs against v1c-interim — the actually-shipped flow. Changes: - Trust model section: replaced step-1c-coming callout with explicit v1c-interim status; cross-refs arch.md §4 (HDKD actor tree), §4a (mental model), §5a (per-actor binding); flags v0.2 target features as not-yet-implemented and tracked in #76 / #79. - Two-machine layout: marked operator-workstation row as "(master role)"; added a "Roles + key inventory primer" callout pointing at arch.md §4a (4-axis mental model), §3 (K1-K11 inventory), §5a.2 (agent role / link-code bootstrap), and the agent wiki page as the operator-focused reference. - Section §0 success-criteria #3: clarifies "operator's omni_account" IS the master actor omni per arch.md §4. What did NOT land in the demo doc: - Per-step rewriting of operational content. The demo correctly exercises v1c-interim (single-omni-shared-with-master, bespoke per-identity PoP, link-code agents). v0.2 demo content waits for the agent-create endpoint + WebAuthn ceremony to ship. * docs(signer): document signer setup + add SIGNER_HOST/AGENTKEYS_SIGNER_URL - scripts/operator-workstation.env: add SIGNER_HOST + AGENTKEYS_SIGNER_URL (derived from BROKER_HOST), keep BACKEND_URL as alias. Co-located with broker today; hostname split lets the signer move to its own machine (or TEE worker) later without changing client config. - docs/cloud-setup.md §1.3: add "what the signer is + why a dedicated hostname" overview with a today-vs-future table; explicit co-location note + cross-ref to operator-workstation.env. - docs/stage7-demo-and-verification.md §0.2: stop re-deriving the signer URL — both vars come from operator-workstation.env now. Cross-ref the topology section in cloud-setup.md. No code change; arch.md §10 deployment topology already captures the separate-hostname / same-host model unchanged. * docs(cloud-setup): extract signer setup into §6 — fix $EIP ordering bug §1.3 used $EIP, but $EIP isn't set until §5.1 — copy-pasting top-down broke. Make §1.3 a brief intro consistent with §1.2 (broker subdomain defers to §5), and put the actual DNS+cert+nginx-flip steps in a new §6 that runs after §5 and reuses $EIP. - §1.3: brief signer intro + defer to §6 (matches §1.2 shape). - §6 NEW: Signer host — overview table (today vs future), DNS A record (§6.1), TLS cert + nginx flip (§6.2), verify (§6.3). - §7: Cleanup (was §6). - Top TOC: add §6 Signer host row, bump Cleanup to §7. - stage7 demo: cross-refs §1.3 → §6 for the cert+DNS steps; cross-ref to "cloud-setup.md §6" cleanup → §7. * docs(cloud-setup): §6.2 — derive SIGNER_HOST on broker host, not from $SIGNER_HOST Reported failure: `sudo certbot --nginx -d "$SIGNER_HOST"` on the broker host fell through to certbot's interactive vhost picker showing only broker.litentry.org. Root cause: $SIGNER_HOST is only exported on the operator workstation (scripts/operator-workstation.env), not on the broker host — empty -d arg → certbot's "pick from existing vhosts" fallback → only the broker vhost is offered. §6.2 now: - explicit warning that $SIGNER_HOST is workstation-only - adds a sanity-check `ls /etc/nginx/sites-enabled/agentkeys-signer` (catches the "setup-broker-host.sh wasn't re-run with signer code" case before certbot is invoked) - derives SIGNER_HOST inline from the nginx vhost (awk the server_name line setup-broker-host.sh just wrote) so the certbot command is copy-paste safe on a fresh broker shell with no env vars set * fix(setup-broker-host): default WITH_NGINX/CERTBOT auto → yes (was: auto → no) Reported failure: `sudo bash scripts/setup-broker-host.sh --yes` on a fresh broker host did not write the agentkeys-signer nginx vhost. Then `sudo certbot --nginx -d signer.` fell through to certbot's interactive vhost picker, which only listed broker. (because the broker vhost was written by an earlier run that had been done with --with-nginx). Root cause: WITH_NGINX defaulted to "auto", which resolved to "no" at line 361 — the comment said "preserves prior default" but every doc-driven operator expects nginx provisioning. The runbook (cloud-setup.md §5 + §6) explicitly assumes nginx is set up by the script. Now: auto → yes for both WITH_NGINX and WITH_CERTBOT. Operators who don't want nginx (running behind a non-nginx reverse proxy, pre-provisioned certs) opt out via --without-nginx / --without-certbot. The interactive preview already prints `nginx : $WITH_NGINX`, so the operator sees the resolved value before confirming. Also pin --with-nginx explicitly in cloud-setup.md §6.2 step 1 + step 3 so the doc remains correct even if the script default changes again. * docs(cloud-setup): §6.1 — warn against re-deriving EIP from local resolver Reported failure: operator's `dig +short broker.litentry.org A` returned 198.18.1.86 (RFC 2544 TEST-NET-2) because their local DNS resolver was behind a transparent proxy (Cloudflare WARP / Zscaler / Tailscale Magic DNS). Using that as $EIP would have published a Route 53 A record pointing at a private/loopback range, breaking Let's Encrypt validation silently — the symptom would surface 5 min later as "Timeout during connect (likely firewall problem)" with the wrong IP in the error. §6.1 now: - explicit callout that local resolvers behind WARP/Zscaler/Tailscale/ corporate VPNs return 198.18.0.0/15 for proxied hostnames - shows `aws ec2 describe-addresses` as the authoritative re-derivation - replaces fire-and-forget verify with a polling loop until Cloudflare DoH confirms the A record matches $EIP (Route 53 propagation up to TTL=300) §5.2 unchanged — within §5 the operator just set $EIP from AWS API in §5.1, so the local-resolver trap doesn't apply there. * docs(cloud-setup): deslop §1.3 + §6 — drop duplicated prose, keep table The §1.3 + §6 + §6.1 + §6.2 prose said the same thing 3-4 times (co-located today / future-split possible / "if the signer is ever moved" / "first run writes nginx, certbot, second run flips ssl"). Each new fix layered another paragraph on top instead of consolidating. Pass 1 — §1.3 collapsed from 12 lines to 1 (matches §1.2's defer-to-§5 shape; §6 has all the detail). Pass 2 — §6 intro: dropped 4-line prose paragraph above the table; folded "endpoints" + "exported as SIGNER_HOST" into the table itself so it's the single load-bearing reference. Dropped trailing prose paragraph about the env file (now in the Public-hostname row). Pass 3 — §6.1: collapsed standalone EIP-derive callout (10 lines of warning + 5 lines of fenced bash) into a 3-line guard inside the bash block (`[ -z "$EIP" ] && EIP=$(aws ec2 describe-addresses …)`). Kept the WARP/Zscaler/198.18.x.x context as a 4-line comment in the bash — load-bearing for diagnosis, would lose meaning if removed. Pass 4 — §6.2: dropped "Three host-side steps. setup-broker-host.sh is idempotent…" preamble paragraph (table already says this). Kept the $SIGNER_HOST=laptop-only callout (load-bearing — distinguishes laptop from broker host shell scope). No behavior change. All cross-refs intact (#6-signer-host, #51-allocate, signer-protocol, operator-workstation.env all still resolve). 60 code fences, balanced. * fix(setup-broker-host): drop --with-nginx / --with-certbot — defaults are yes The flags were redundant once defaults flipped to yes (commit a3a0a84). Per CLAUDE.md remote-broker-host policy the script is the single idempotent entry point — flag-gating "do the thing the runbook always wants" is noise. Drop both --with-* flags + the auto-resolution dead-code; keep --without-nginx / --without-certbot as the only opt-out. - WITH_NGINX / WITH_CERTBOT default to "yes" outright (no more "auto" three-state); 12-line auto-resolution block becomes a 2-line comment. - CLI parser drops --with-nginx / --with-certbot. Passing the removed flags now errors `unknown flag: --with-nginx` rather than silently no-op'ing. - Header usage block + interactive defaults comment updated to match. - docs/cloud-setup.md §6.2: drop --with-nginx from both invocations (replace_all over the doc). No behavior change for operators following the runbook — `--yes` alone already provisioned nginx since a3a0a84. This commit only removes the explicit `--with-nginx` redundancy. * docs(claude+stage7): runbook-fix-fold-back policy + absorb session fixes CLAUDE.md - New "Runbook-fix-fold-back policy": when an operator hits a runbook failure, both the targeted fix AND a runbook revision must land in the same turn. Goal: every operator-encountered failure makes the runbook strictly more robust before we move on. stage7-demo-and-verification.md (§0) Absorbs every failure the operator hit walking this PR end-to-end: - §0 Tooling: pulled CLI build out of a sub-bullet into a numbered ordered checklist (cargo build → cp to ~/.local/bin → which/version smoke-test → init). Explicit warning against path-relative aliases (the recurring "alias agentkeys=./target/release/agentkeys-cli" trap with the wrong binary name from before the agentkeys-cli → agentkeys rename). Spells out crate-name vs binary-name distinction. - §0.1: branch-agnostic checkout via `BRANCH="${BRANCH:-evm}"` (was hardcoded `git checkout evm` — broke when validating PR branches). Adds nginx vhost sanity-checks: `ls /etc/nginx/sites-enabled/ agentkeys-{broker,signer}` + grep for proxy_pass-vs-return-503 inside agentkeys-signer (catches the "cert issued but script not re-run, vhost still serves stub 503" failure mode). - §0.2: smoke-test now string-matches body == "ok" (a successful HTTP 200 with body "TLS cert not yet issued for signer …" is the exact trap operators hit when certbot succeeded but step 3 of §6.2 wasn't run). Adds a 5-row "common failure modes" table mapping observed body → cause → exact fix command. §16 line 1402's `git checkout evm` left as-is — that section is intentionally evm-specific (verifies the live prod broker). * docs(stage7): §0 install — drop conflicting aliases + verify $PATH wins Operator hit `which agentkeys` → "aliased to ./target/release/agentkeys-cli" even after `cp target/release/agentkeys ~/.local/bin/`. zsh aliases beat $PATH lookups (and the alias also pointed at the wrong binary name — the crate is agentkeys-cli but the [[bin]] is `agentkeys`), so the install was invisible no matter how correctly it was staged. §0 build checklist now goes 5 steps in this order: 1. sed-strip any `alias agentkeys[-= ]…` from ~/.zshenv + ~/.zshrc (with .bak), then `unalias` for the current shell. Fail-soft (`|| true`) so missing files don't abort. 2. Append `~/.local/bin` to $PATH if not already there (idempotent case statement; appends to ~/.zshenv). 3. cargo build (was step 1). 4. cp to ~/.local/bin (was step 2). 5. `hash -r` + `command -v agentkeys` (NOT `which`) — bypasses any alias zsh hasn't re-hashed away yet. Spells out the expected absolute-path output. Plus a tiered fallback callout: if `command -v` still shows the alias, grep ~/.zprofile / ~/.aliases / shell includes for stragglers, then `exec zsh -l`. Per Runbook-fix-fold-back policy (CLAUDE.md): operator failure → both the fix command (handed back inline last turn) AND the runbook revision land in the same turn. Next operator running this top-down won't hit the alias trap. * docs(stage7): §0.2 — pin BACKEND_URL inline + bail-loud on stale value Operator hit `curl: (7) Failed to connect to 127.0.0.1 port 18090` because their shell had a stale `BACKEND_URL=http://127.0.0.1:18090` local-dev export in ~/.zshenv that shadowed operator-workstation.env's BACKEND_URL=$AGENTKEYS_SIGNER_URL alias. §0.2 now: - Pins `export BACKEND_URL="$AGENTKEYS_SIGNER_URL"` inline so the smoke-test is self-contained (no longer depends on ~/.zshenv being un-shadowed). - Adds a defensive `case "$BACKEND_URL" in https://signer.*) ;; esac` bail-loud check BEFORE the curl, with a one-line diagnosis (`grep -n BACKEND_URL ~/.zshenv && unset && re-source`). - Echoes BACKEND_URL alongside SIGNER_HOST so the operator visually confirms the value is public https:// before hitting curl. Per Runbook-fix-fold-back: failure command + cause + fix command all inline in the runbook so the next operator with a stale local-dev shell doesn't have to round-trip with the maintainer to diagnose. * Revert "docs(stage7): §0.2 — pin BACKEND_URL inline + bail-loud on stale value" This reverts commit 11e59ce5da0b20d12bf6c07909160c506ce4d101. * docs(stage7): fix --json position — global flag, must precede subcommand Operator hit `error: unexpected argument '--json' found` running §0.4's `agentkeys signer derive --signer-url … --omni-account … --json`. Per crates/agentkeys-cli/src/main.rs:24-25, --json is a top-level flag on the root `agentkeys` command (controls ctx.json_output globally), NOT a per-subcommand flag on `signer derive` / `signer sign`. Clap rejects it after the subcommand's required args. Eight occurrences fixed across §0.4 (×2), §3 SIG_A/SIG_ADDR/SIG_B (×3 multi-line), and §16 live walkthrough (×3 single-line): agentkeys signer derive … --json | jq … → agentkeys --json signer derive … | jq … agentkeys signer sign … --json | jq … → agentkeys --json signer sign … | jq … Plain text-output calls at lines 1047 and 1099 left unchanged (no --json there to begin with). Per Runbook-fix-fold-back: clap arg ordering is non-obvious for top-level vs subcommand flags, so the runbook command examples must match the actual CLI grammar — operators copy-paste, they don't re-read the clap macro. * docs(stage7): §0.4 — inline `agentkeys init --email` step before derive Operator hit `Error: SIGNER_UNAUTHORIZED invalid session JWT: InvalidToken` running §0.4's first signer derive call. The §0.4 intro said "Run agentkeys init first if you haven't already" but never showed the actual command — operators don't know to look ahead 100 lines to §2.0 for the real `--email --broker-url --signer-url` invocation. §0.4 now: - Explicit "must run first OR every call below returns SIGNER_UNAUTHORIZED" callout (with the literal error message so operators searching the doc for the error find the fix). - Inline `agentkeys init --email alice@demo.example --broker-url $OIDC_ISSUER --signer-url $BACKEND_URL` as a copy-paste block, with the expected "Initialized via email-link" output. - Cross-link to §2.0 for explanation + OAuth2 alternative — minimal in §0.4, full context in §2.0. §2.0's existence preserved: it still has the magic-link explanation + OAuth2 alternative + daemon-side equivalent. §0.4's inline init is the minimum to keep the §0 prereq chain self-contained. Per Runbook-fix-fold-back: a runbook step that says "run X first" must include the literal X invocation, not just point at it. * feat(broker): real SES email sender — Pass 1 of Option B Pass 1 implementation per .omc/ralph/prd.json: ships the SesEmailSender behind the auth-email-link feature, with end-to-end SES → S3 round-trip integration test. Pass 2 (separate commit) wires boot.rs + setup-broker-host.sh + broker.env defaults + demo doc. Closes the gap that blocked the operator's stage-7 demo init flow: the deployed broker had only StubEmailSender (in-process Vec, no delivery). With this change + Pass 2, `agentkeys init --email` will deliver a real magic-link to the operator's inbox. US-1: Cargo.toml deps - aws-sdk-sesv2 = "1" added as optional dep gated by auth-email-link - aws-sdk-s3 + uuid added to dev-dependencies for the integration test - dev-deps now enable auth-email-link so tests/* compile by default US-2: SesEmailSender impl (crates/agentkeys-broker-server/src/plugins/auth/email_link.rs) - send_magic_link composes multipart text+html via aws-sdk-sesv2 SendEmail - verify_sender_ready calls GetEmailIdentity + checks verified_for_sending - Errors map to EmailSendError::{Send, Verify, Config} - Inline subject + body templates (no template-engine dep) - Re-exported from src/plugins/auth/mod.rs US-3: Body composition unit tests (4 added) - ses_subject_is_non_empty - ses_text_body_contains_landing_url - ses_html_body_contains_landing_url_twice (href + visible text) - ses_text_and_html_alternatives_both_present US-4: Integration test (crates/agentkeys-broker-server/tests/ses_email_flow.rs) - Gated by RUN_SES_INTEGRATION_TESTS=1 + #[ignore] - CleanupGuard Drop impl: list-and-delete every S3 object whose body contains the per-test UUID, even on panic - Polls inbound/ prefix for up to 60s (5s × 12 attempts) - Asserts MIME body contains both unique token AND landing URL (allowing for quoted-printable encoding of '=' as '=3D') US-5: Quality gates ALL GREEN - cargo build -p agentkeys-broker-server → exit 0 - cargo build -p agentkeys-broker-server --features auth-email-link → exit 0 - 161 lib tests pass; integration test compiles + skips gracefully - cargo clippy --no-deps -- -D warnings → exit 0 - (Pre-existing clippy warning in agentkeys-core/src/init_flow.rs:177 unrelated; will tackle in Pass 2 if it blocks.) US-6: BLOCKED on operator — live SES round-trip - Operator runs: awsp agentkeys-admin RUN_SES_INTEGRATION_TESTS=1 ACCOUNT_ID=429071895007 \ cargo test -p agentkeys-broker-server --features auth-email-link \ --test ses_email_flow -- --ignored --nocapture * fix(broker): SesEmailSender verify — fall back from address to domain identity Operator hit `NotFoundException: Email identity does not exist` running the SES integration test. Cause: SES GetEmailIdentity returns identities EXPLICITLY registered with `create-email-identity`. cloud-setup.md §2.1 verifies the DOMAIN (`bots.litentry.org`), which auto-grants sending rights to ANY address at that domain via DKIM — but the per-address identity (`noreply@bots.litentry.org`) was never registered. So the verify precheck failed even though the actual SendEmail would succeed. Fix: verify_sender_ready now tries address-level lookup first (preferred — explicit), then on NotFound falls back to extracting the domain (split on '@') and looking up the domain identity. Either passing → Ok(()). Helper extracted: check_identity(client, identity) → Result<(), String> returns Ok only when SES reports the identity exists AND verified_for_sending_status=true. Used by both attempts. No behavior change for operators who explicitly verify per-address; unblocks the canonical operator path (verify-domain-only) per cloud-setup.md §2.1. Closes the verify-precheck blocker on Pass 1's US-6 (live SES round-trip from operator). Quality gates re-checked: - cargo build -p agentkeys-broker-server --features auth-email-link → ok - cargo test -p agentkeys-broker-server --features auth-email-link --lib → 161 passed - cargo clippy -p agentkeys-broker-server --features auth-email-link --tests --no-deps -- -D warnings → ok * feat(ses): explicit per-address verify + ses-verify-sender.sh helper Per operator request after Pass 1: 1. drop the address→domain fallback in SesEmailSender::verify_sender_ready — explicit per-address verification only 2. register noreply-test@bots.litentry.org as a per-address SES identity and pin it in operator-workstation.env 3. give the operator a one-shot bash helper that exploits the existing SES inbound receipt rule (cloud-setup.md §2.1) to fully automate the address verification — no inbox-clicking, no manual MIME parsing Code (crates/agentkeys-broker-server/src/plugins/auth/email_link.rs): - verify_sender_ready: single GetEmailIdentity call on the FROM address. No fallback. Error message points the operator at `aws sesv2 create-email-identity` (and at scripts/ses-verify-sender.sh for the automated path) so the next failure self-diagnoses. - Removed check_identity helper (was the fallback shared call). Test (crates/agentkeys-broker-server/tests/ses_email_flow.rs): - TestEnv now reads BROKER_EMAIL_FROM_ADDRESS — same env var the broker reads at runtime (env.rs:143). One source of truth between the test + the broker process. - Default: noreply-test@${MAIL_DOMAIN} (was: hardcoded noreply@…). Env (scripts/operator-workstation.env): - New: MAIL_DOMAIN (bots.litentry.org), MAIL_BUCKET, BROKER_EMAIL_FROM_ADDRESS. - MAIL_DOMAIN is explicit (not derived from BROKER_HOST) — broker zone may differ from email subdomain. Helper (scripts/ses-verify-sender.sh, +x): - One-shot: aws sesv2 create-email-identity → poll s3://$MAIL_BUCKET/inbound/ for the SES verification mail (lands there via the existing receipt rule from cloud-setup.md §2.1) → grep verification URL out of the quoted-printable body → curl-click it → confirm VerifiedForSendingStatus → delete the verification mail from S3 so it doesn't pollute the inbox. - Idempotent: re-running on a verified identity exits 0 immediately. - Requires: aws + jq + curl + grep + sed (all present on macOS / Ubuntu). Quality gates: - cargo build -p agentkeys-broker-server → ok - cargo build -p agentkeys-broker-server --features auth-email-link → ok - cargo test -p agentkeys-broker-server --features auth-email-link --lib → 161 passed - cargo test -p agentkeys-broker-server --features auth-email-link --test ses_email_flow → 1 ignored (skips) - cargo clippy -p agentkeys-broker-server --features auth-email-link --tests --no-deps -- -D warnings → ok * fix(ses-verify-sender): drop FROM-grep prereq — never matched QP-encoded body Operator hit "endless waiting" — the script polled S3 forever even though SES had likely written the verification mail. Two bugs in the polling predicate: 1. `grep -q "$FROM"` looked for the literal `noreply-test@bots.litentry.org` string, but in a quoted-printable MIME body the `@` is encoded as `=40` so the literal grep never matched. 2. `grep -qE 'ses[._-]?verification|amazonaws\.com.*verify'` matched `ses-verification` patterns, but the actual SES URL host is `email-verification..amazonaws.com` — neither alternative hit. Fix: drop both prereq greps. SES verification URLs are unique enough that matching the URL pattern directly is sufficient — no false positives. Also added per-attempt diagnostics: - log "$count object(s) under inbound/" each iteration so the operator can see whether anything is landing at all - on timeout: structured 3-step diagnosis pointing at receipt-rule state, identity status, and bucket contents Refactored URL extraction into extract_verify_url() helper (single source of truth) — handles quoted-printable soft-wrap (=\n) + =3D decoding. * fix(ses-test): CleanupGuard Drop — block_in_place to allow nested block_on Operator hit the test panic at line 145: "Cannot start a runtime from within a runtime. This happens because a function (like `block_on`) attempted to block the current thread while the thread is being used to drive asynchronous tasks." Cause: `Handle::block_on` is forbidden when called from inside a tokio runtime context. Drop runs WHILE still inside #[tokio::test]'s runtime (the runtime hasn't shut down by the time Drop fires for `let _guard =`), so the previous code panicked even though we had `try_current → Ok` to "detect" the active runtime. Test ran end-to-end successfully BEFORE this Drop panic — log shows: ses_email_flow: found inbound object key=inbound/8dqr… (attempt 1) …the assertions never got to run because Drop tore down first. Fix: wrap `handle.block_on(cleanup_fut)` in `tokio::task::block_in_place`, which suspends the current async task so a nested blocking call is legal. Requires multi_thread runtime — already guaranteed by `#[tokio::test(flavor = "multi_thread")]` on the test attribute, no behavior change for the rest of the test. The `Err(_) → Runtime::new()` branch is preserved as a fallback for the edge case where Drop fires AFTER the runtime has been torn down (e.g. test panic during runtime shutdown). Won't normally trip in practice. * fix(ses-test): unbuffered per-attempt logging + bounded object scan Operator hit "test has been running for over 60 seconds" with no per-attempt log lines visible. Two underlying problems: 1. println! is line-buffered, and `cargo test --nocapture` pipes stdout (not a TTY), so the per-attempt "attempt N/12 — sleeping" lines were buffered until end-of-test. Looked like a hang from the operator side. 2. The poll loop did `list_objects_v2()` then iterated EVERY object's body. With cumulative SES inbound (test runs + verification mails), each iteration could scan dozens of objects, which is both slow and buries the relevant log lines. Fix: - New `log()` helper writes to STDERR (unbuffered) + explicit flush after every line. Operator sees progress in real time. - `eprintln!` for every step: * configuration echo (account / region / bucket / from / to / token) * verify_sender_ready in-progress + result * send_magic_link in-progress + result * per-attempt: list_objects_v2 call + total bucket size + how many we'll examine * per-object: index/total, key, size in bytes, contains-token Y/N * found / not-found summary per attempt - Scan limit: sort objects by LastModified desc, examine only the 20 most recent per iteration. Keeps the loop fast even when the bucket has thousands of stale objects. - list_objects_v2 errors no longer expect-panic; logged + retried next iteration. Gives the test a chance to recover from transient throttling. - Timeout panic now lists the 4 most likely root causes (sandbox + unverified recipient, suppressed address, receipt-rule inactive, region mismatch) with the diagnostic command to check each. No behavior change to the AWS interactions — purely observability + robustness against transient errors. * fix(ses-test): explicit async cleanup via catch_unwind — no more Drop guard Operator hit "test ok — CleanupGuard will purge inbound objects on Drop" followed by … nothing. No "deleted" log line ever printed. Bucket has 415 stale objects from prior runs — cleanup has been silently failing for a while. Root cause: Drop fires WHILE the tokio runtime is in shutdown handoff. `block_in_place` + nested `block_on` is touchy in that window — runs silently, hangs, or both. The pattern was wrong from the start. Fix: drop the Drop-based pattern entirely. - Test body extracted into `run_send_and_poll(...)` helper. - Outer test fn wraps it in `AssertUnwindSafe(...).catch_unwind().await` — captures any panic into Result without unwinding. - `cleanup_test_objects(...)` runs ALWAYS, in plain async context, with the same unbuffered `log()` helper as the test body. Logs every key it inspects + every delete + final count. - Captured panic is re-raised AFTER cleanup so test failure semantics are unchanged: the test still fails on assert! / expect, just AFTER cleanup has visibly run. Required new dev-dep: `futures-util = "0.3"` for `FutureExt::catch_unwind` on async futures. Standard tokio-test pattern. Net: cleanup now runs inside the runtime as a normal async call, can't hang on shutdown handoff, and prints every step. Note for operator: the existing 415 stale objects need a one-shot purge. Run from operator workstation: aws s3 ls s3://agentkeys-mail-${ACCOUNT_ID}/inbound/ --recursive | awk '{print $4}' | while read -r key; do body=$(aws s3 cp "s3://agentkeys-mail-${ACCOUNT_ID}/$key" - 2>/dev/null) if echo "$body" | grep -q 'magic-link-test-'; then aws s3 rm "s3://agentkeys-mail-${ACCOUNT_ID}/$key" fi done * perf(ses-test): cleanup fast-path — single DeleteObject vs 415-object scan Test took 211s end-to-end. Poll was instant (attempt 1, found in 1 RPC). Cleanup was the bottleneck: scanned all 415 inbound/ objects, fetching each body to check the per-test UUID. ~415 GetObject × ~500ms = ~3 min. Fix: poll already knows the exact key it found — pass it to cleanup. - run_send_and_poll takes Arc>> as found_key_slot and writes the matching key into it on hit. - Outer fn drains the slot post-catch_unwind and passes Option to cleanup_test_objects(s3, bucket, token, fast_key). - cleanup_test_objects: if fast_key=Some, single DeleteObject (~1 RPC). - Slow scan path preserved for the panic-before-find case (rare). Per-token body match retained for the slow scan — production-safe via UUID collision probability of ~10^-38. Expected runtime drop: 211s → ~5s (1s SendEmail + 1s ListObjects + 1s GetObject + 1s DeleteObject + ~1s overhead). * feat(broker): Pass 2 of Option B — wire SesEmailSender end-to-end Closes the original gap that blocked stage-7 demo init: the deployed broker had only `wallet_sig` enabled, was built without `auth-email-link`, and `agentkeys init` only supports email/oauth2 — so the broker fundamentally couldn't be initialized via the CLI. Pass 2 wires the SesEmailSender (from Pass 1) into broker boot + deployment, so `agentkeys init --email` works end-to-end against the deployed broker. Code: - crates/agentkeys-broker-server/src/env.rs: new BROKER_EMAIL_SENDER env var (`stub` | `ses`, default stub for back-compat). - crates/agentkeys-broker-server/src/boot.rs: branch on BROKER_EMAIL_SENDER. When `ses`, construct SesEmailSender via aws_config::defaults().load() using block_in_place + block_on (legal under multi-thread #[tokio::main]). When `stub`, preserve previous behavior. Unknown value → boot_fail. Deployment: - scripts/setup-broker-host.sh: * cargo build now passes `--features auth-email-link` (previously default-features only — that was the structural gap). * New section 4b: mints /etc/agentkeys/email-hmac.key (32 random bytes via openssl rand, mode 0600, owner agentkeys). Idempotent. * agentkeys-broker.service systemd unit gets new env vars: BROKER_AWS_REGION, BROKER_AUTH_METHODS=wallet_sig,email_link, BROKER_EMAIL_SENDER=ses, BROKER_EMAIL_FROM_ADDRESS=..., BROKER_EMAIL_HMAC_KEY_PATH=/etc/agentkeys/email-hmac.key. * New `--email-from ` CLI flag + BROKER_EMAIL_FROM_ADDRESS env var fallback (default noreply-test@bots.litentry.org). Env defaults: - scripts/broker.env: BROKER_AUTH_METHODS now includes email_link; documented BROKER_EMAIL_SENDER, BROKER_EMAIL_FROM_ADDRESS, BROKER_EMAIL_HMAC_KEY_PATH. Quality gates: - cargo build --features auth-email-link → ok - cargo test --features auth-email-link --lib → 161 passed - cargo clippy --features auth-email-link --tests --no-deps -- -D warnings → ok - bash -n scripts/setup-broker-host.sh → ok What's next (this commit doesn't include): - GH issue documenting the original gap (item 3 of operator's request). - stage7-demo doc updates to confirm the now-working init flow (item 4). * docs: backfill issue #80 reference in setup-broker-host.sh comment * docs(stage7): §0.4 + §2.0 — add Pass-2 prereqs (ses-verify-sender + auth-email-link build) Operator hit issue #80 walking the demo: the deployed broker rejected /v1/auth/email/request with 404. Pass 2 of Option B (8ef973a) closed the gap — broker now builds with --features auth-email-link, has BROKER_AUTH_METHODS=wallet_sig,email_link, and uses real SesEmailSender. Demo doc updates: - §0.4: new "two-step prereq" callout listing the ses-verify-sender.sh step + the broker-host re-deploy. Cross-refs issue #80 so operators who Google the failure find the fix. - §2.0: brief prereq pointer + acknowledgment that magic-link is now delivered via real SES (FROM noreply-test@bots.litentry.org), not the prior in-process StubEmailSender. No operational step changes — just makes the documented init flow match what's actually deployable end-to-end after Pass 2 lands. * refactor(email_link): drop vestigial HMAC key — magic-link is stateful per arch.md Operator pointed out that HMAC isn't in our K-table architecture: docs/spec/architecture.md §3 (K1–K11 inventory) lists no HMAC key, and §5a.1.M Stage 1 + §4 row "email-link" describe the magic-link as **stateful**: "Broker emails magic link; operator clicks; broker confirms single-use within TTL." Audit showed `EmailLinkAuth.hmac_key` was loaded + validated (≥32 bytes) but **never used cryptographically anywhere in the email_link module**. Verified by `grep -rn 'self\.hmac_key\|sign_token\|HmacSha\|Mac::new' crates/agentkeys-broker-server/src/plugins/auth/email_link.rs` → zero matches. Vestigial dead code from an earlier design that planned self-verifying tokens but never landed. The actual security comes from: - Token randomness (32 bytes CSPRNG via getrandom) - SHA256(token) lookup (no plaintext token in SQLite) - TTL check (10 minutes per Plan §3.5.3) - Single-use enforcement (consume_token marks consumed) No HMAC needed. Remove the dead weight + the operator-facing wiring: Code: - crates/agentkeys-broker-server/src/plugins/auth/email_link.rs: drop `hmac_key` field, constructor param, length validation; drop `hmac_key_too_short_rejected` test; drop `vec![0u8; 32]` from test helper; drop now-unused `use crate::env;`. - crates/agentkeys-broker-server/src/boot.rs: drop hmac_path/hmac_key load block; drop arg from EmailLinkAuth::new call; reframe boot_fail anchor to BROKER_EMAIL_FROM_ADDRESS (the still-required var). - crates/agentkeys-broker-server/src/env.rs: drop BROKER_EMAIL_HMAC_KEY_PATH constant + introspection table entry. - crates/agentkeys-broker-server/tests/email_flow.rs: drop `vec![0u8; 32]` from EmailLinkAuth::new call. Deployment: - scripts/setup-broker-host.sh: drop section 4b (email-hmac.key generation); drop Environment=BROKER_EMAIL_HMAC_KEY_PATH from systemd unit. - scripts/broker.env: drop BROKER_EMAIL_HMAC_KEY_PATH entry; replace with explanatory comment pointing at arch.md §5a.1.M. Demo: - docs/stage7-demo-and-verification.md §0.4 prereq + §2.0 prereq: drop "+ email-HMAC key" wording; reference arch.md §5a.1.M for the stateful design rationale. OAuth2's state_hmac_key (oauth2/mod.rs:394) is unaffected — that one IS load-bearing (HmacSha256 signs the OAuth state parameter for integrity across redirect). Quality gates: - cargo build -p agentkeys-broker-server → ok - cargo build -p agentkeys-broker-server --features auth-email-link → ok - cargo test -p agentkeys-broker-server --features auth-email-link --lib → 160 passed (was 161; -1 = removed hmac_key_too_short_rejected) - cargo clippy --features auth-email-link --tests --no-deps -- -D warnings → ok - bash -n scripts/setup-broker-host.sh → ok * docs(policy): add no-hardcoded-values policy + hardcoded.md audit log Operator request: enforce that no hardcoded values land in scripts/code/ runbooks unless logged in a dedicated audit doc. CLAUDE.md - New "No-hardcoded-values policy" between Runbook-fix-fold-back and Plan-completion. Says: parameterize via env / CLI / config; if temporarily hardcoded, log in hardcoded.md with file+line, why, and the unblock action. hardcoded.md (NEW) - Seeded with the existing operator-deployment-pinned values (ACCOUNT_ID, BROKER_HOST, MAIL_DOMAIN, BROKER_EMAIL_FROM_ADDRESS, BROKER_DATA_ROLE_ARN), the deployment-architecture-pinned values (loopback ports 8090/8091/8092, agentkeys system user, /etc/agentkeys paths), and code-level constants (TOKEN_TTL_SECONDS, rate-limit defaults, SES integration test defaults). - Each entry: what's hardcoded, why, what would unblock making dynamic. - Open trade-off section flags the email_link HMAC removal (b8481fe) for revisit when scaling to multi-broker-replica deployments. scripts/broker.env (smell fix called out in hardcoded.md) - Add ACCOUNT_ID=429071895007 as the single source of truth. - Derive BROKER_DATA_ROLE_ARN from \${ACCOUNT_ID} (was hardcoded separately, drifted from operator-workstation.env's ACCOUNT_ID). - Verified: `set -a; source ./scripts/broker.env; set +a` expands ACCOUNT_ID + BROKER_DATA_ROLE_ARN correctly. * docs(hardcoded): cross-link HMAC trade-off to issue #81 — bidirectional traceability * fix(ses-verify-sender): fail loud on wrong AWS profile + fold profile switch into stage7 doc The script previously masked AccessDenied from list-objects-v2 with '2>/dev/null || true', manifesting as endless 'attempt N/24 - 0 object(s) under inbound/' polling when the operator forgot to switch to agentkeys-admin profile (the broker user lacks s3:ListBucket on the mail bucket per cloud-setup.md section 2.1). Two changes: 1. Script now preflights 'aws sts get-caller-identity' + a ListObjectsV2 probe before entering the poll loop. Wrong-profile case dies with explicit 'Run: awsp agentkeys-admin' guidance instead of silently spinning. Also drops the 2>/dev/null mask on the poll-loop list call now that preflight proves the cred path. 2. Stage 7 demo doc section 0.4 prereq block now shows the awsp + set -a;source;set +a sequence inline, with a callout naming the previous failure mode so the next operator recognizes it immediately. Reproduced locally: AWS_PROFILE=agentkey-broker bash scripts/ses-verify-sender.sh -> exits 1 with: 'wrong AWS profile: arn:...:user/agentkey-broker lacks s3:ListBucket on agentkeys-mail-429071895007. Run: awsp agentkeys-admin then re-run this script.' User approved one-shot raw-git use because this dir is a git-linked worktree (.git is a file pointing back to parent repo); jj root resolves to parent and cannot see these paths. * fix(setup-broker-host): die loud with journal on healthz failure post-restart Root cause: the post-restart healthz check used a single 5s curl with '|| warn' — a service in systemd Restart=always loop (e.g. broker crashing on BROKER_AUTH_METHODS=email_link with binary built without --features auth-email-link) shows up as a one-line warn the operator scrolls past, and the script exits 0. Operator declares the host healthy, then 30 minutes later hits 502 Bad Gateway from nginx and has to re-diagnose from scratch. Three changes: 1. scripts/setup-broker-host.sh — replace the warn-only one-shot curl probes with probe_or_die(): poll /healthz for 20s per service (10x 2s with --max-time 2), and on persistent failure dump 'systemctl status' + last 40 journal lines for the failing unit, then die with a fix-list naming the three most common boot crashes (gated-out feature, missing FROM address, AWS creds). 2. docs/stage7-demo-and-verification.md §0.4 prereq #2 — instruct operator to 'rm -f target/release/agentkeys-broker-server' before re-running the script (cargo's incremental cache occasionally leaves the wrong artifact in place when feature flags change across rebuilds; clean target avoids the failure mode entirely). Plus a '502 Bad Gateway' troubleshooting block pointing at the journal grep + the canonical fix. 3. Same doc — name the exact boot-crash error string ('unknown or feature-gated-out auth method') the next operator will see, so they don't have to round-trip with logs. Per runbook-fix-fold-back policy: every operator-encountered failure makes the runbook strictly more robust before we move on. * deslop(setup-broker-host): drop dead helpers + dedupe + fix latent cred-mode case bug Pass-by-pass cleanup of scripts/setup-broker-host.sh, behavior preserved (verified by grep-locking 17 critical strings: env vars, ports, paths, systemd unit names, feature flags, function calls). Net -75 lines (1019 -> 944, -7.4%). Pass 1 — Dead code: - Drop prompt_default() and prompt_choice() (defined but never called). - Drop --skip-pull flag, PULL_SKIP var, and the redundant '! $PULL_SKIP' guard (the outer '[[ -n "$PULL_REF" ]]' already gates the pull). --skip-pull is now folded into the --upgrade no-op arm so existing callers still parse cleanly. Pass 1b — Latent bug fix: - The 'case "$CRED_MODE"' block in the trailing manual-steps section had a duplicate 'instance-profile)' arm: the FIRST one was reached but contained text describing 'none mode'; the SECOND (which had the correct instance-profile text) was unreachable dead code; and 'none' mode users got NO instructions at all because no 'none)' arm existed. Renamed the first arm to 'none)' so all three modes now print their intended manual-steps text. Pass 2 — Duplicate consolidation: - Three near-identical 'if [[ -d /etc/nginx/sites-enabled ]]; then ln -sf … fi' blocks (broker, signer-HTTPS, signer-HTTP-only) collapsed into ONE block after write_nginx_site returns. ln -sf is idempotent so this is behavior-equivalent. - certbot install: 'case "$PM"' had two arms with identical package list ('certbot python3-certbot-nginx'); collapsed to a single '"${PM_INSTALL[@]}" certbot python3-certbot-nginx' invocation. Pass 3 — Comment trim: - 58-line header reduced to 18 lines: dropped the 'Order of operations' enumeration (duplicated by the section comments inline) and the --flag enumeration (duplicated by the case parser + --help dump). Kept the canonical 'CLAUDE.md says all remote-host changes go through this script' rule + out-of-scope list. Idempotency audit (no changes needed — already correct): • build deps: apt/dnf -y, idempotent • rustup install: gated 'if ! have rustup' • systemctl stop: '|| true' • binary backup: gated 'if [[ -x ]]' • install -m 0755: overwrite-OK • useradd: gated 'if ! id -u agentkeys' • install -d: idempotent • DEV_KEY_SERVICE secret: gated 'if ! sudo test -s' (never regenerated) • systemd unit writes: tee overwrites — intended each run • nginx install: gated 'if ! have nginx' • nginx site write: tee overwrites — intended (handles HTTP→HTTPS flip) • sites-enabled ln -sf: -f forces, idempotent • certbot install: gated 'if ! have certbot' • ensure_broker_keypairs: per-keypair 'if sudo test -f' guard • daemon-reload, enable, restart: idempotent Verification: bash -n scripts/setup-broker-host.sh # syntax ok grep -F locked 17 critical strings # all present * fix(setup-broker-host): cargo multi-package + --features footgun strips auth-email-link Root cause of the broker host's repeated 'BOOT_FAIL: BROKER_AUTH_METHODS= "email_link": unknown or feature-gated-out auth method' even after a fresh target/ rebuild: the script used a SINGLE cargo invocation to build BOTH agentkeys-mock-server AND agentkeys-broker-server with '--features agentkeys-broker-server/auth-email-link', and cargo silently DROPS the feature flag in this multi-package selection mode. Reproduced empirically with --message-format json: cargo build --release -p agentkeys-mock-server -p agentkeys-broker-server \ --features agentkeys-broker-server/auth-email-link → broker compiled features: [audit-sqlite, auth-wallet-sig, default, wallet-keystore] ← NO auth-email-link vs the working separate form: cargo build --release -p agentkeys-broker-server --features auth-email-link → broker compiled features: [audit-sqlite, auth-email-link, auth-wallet-sig, default, wallet-keystore] ← present Fix: 1. Split the build into two separate cargo invocations — mock-server alone (default features), broker-server alone with the feature flag. Documented the footgun in a long block comment so the next person who 'optimizes' by re-merging them will read why before doing it. 2. Added a post-build sanity check: 'strings target/release/agentkeys- broker-server | grep /v1/auth/email/(request|verify)' must match before install + restart. If the cargo footgun ever resurfaces (or anyone introduces a similar feature-strip bug), the script dies HERE with a clear diagnostic instead of after install + systemd restart loop + journal dump. Verified locally: bash -n scripts/setup-broker-host.sh # syntax ok strings target/release/agentkeys-broker-server | grep /v1/auth/email → /v1/auth/email/request /v1/auth/email/verify /v1/auth/email/status /v1/auth/email/landing (all four routes present) * fix(setup-broker-host): assert via cargo --message-format=json + cargo clean -p The previous fix (commit 6d75599) split the cargo build into separate invocations to defeat the multi-package + --features footgun, but the broker host STILL deployed binaries lacking auth-email-link. Two real root causes survived: 1. CARGO INCREMENTAL CACHE: 'rm -f target/release/agentkeys-broker-server' only removed the output binary, not target/release/deps/.fingerprint/ nor the per-feature-set cached .rlib deps. On a host that previously built without auth-email-link, cargo's incremental could relink from stale deps and produce a binary missing the feature even when the build call was correct. Fix: 'cargo clean -p agentkeys-broker-server --release' before the rebuild — only ~1s, only this crate's cache. 2. WEAK VERIFICATION: 'strings | grep -qE "/v1/auth/email/request"' is a heuristic that: - false-positives on tower middleware names containing 'email' - false-negatives when LTO dedupes string literals across the binary - dies with an unactionable 'this is the cargo footgun' guess that was wrong (the call was correct; the host environment was the bug) Replace with: parse cargo's own --message-format=json output and ASSERT auth-email-link is in the bin artifact's features list. Cargo's reported features ARE the truth — no heuristic. Critical bash detail: cargo --message-format=json sends NDJSON to stdout and compiler messages to stderr. Merging them with '2>&1' corrupts the NDJSON and jq dies with 'Invalid numeric literal at line N column M'. The script now redirects them to separate temp files (BUILD_JSON / BUILD_ERR) and only mixes them in the diagnostic 'tail -30' on failure. The strings check is kept as belt-and-suspenders (catches the 'cargo claims success but binary on disk is stale' edge case). Switched to 'grep -aFq' per codex review: -a forces text mode (some Linux strings implementations differ on binary detection), -F treats the route as a fixed string (no regex interpretation of '/'). If cargo reports auth-email-link is NOT enabled despite --features auth-email-link, the new die message lists 5 specific things to check ($HOME/.cargo/config.toml, workspace .cargo/config.toml, env vars, 'which cargo', Cargo.lock drift) instead of guessing. Verified locally: - cargo clean -p removes 17 files / 61.8MiB (only broker artifacts) - cargo --message-format=json reports features=[audit-sqlite, auth-email-link, auth-wallet-sig, default, wallet-keystore] - assertion passes; strings check passes * docs(stage7): fold-back build-time vs boot-time auth-email-link failure paths Per CLAUDE.md runbook-fix-fold-back: now that scripts/setup-broker-host.sh catches the cargo-feature-not-enabled case at build-time (commit c235373's --message-format=json assertion), the operator-facing troubleshooting needs two distinct entries: 1. Build-time die ('cargo did NOT enable auth-email-link'): host has a .cargo/config.toml or env-var override; script lists 5 things to check before the operator should file an issue. 2. Boot-time BOOT_FAIL: now historical (defended by both cargo clean -p AND the JSON assertion); kept as a fallback diagnostic for the case where the broker was started outside the script. If the boot-time BOOT_FAIL ever recurs on a fresh re-deploy, the doc now points the operator at 'bash -x' tracing instead of the previous generic 'rm -f && re-run' fix that no longer applies. * fix(setup-broker-host): trust cargo's JSON assertion; demote strings/nm to warn Reported failure: on Ubuntu with rustc 1.95.0, the script dies with 'binary on disk does not match cargo's reported feature set' even though cargo --message-format=json correctly reports auth-email-link is enabled. The 'strings | grep' belt-and-suspenders check is a false negative on this combination — likely rustc 1.95 MIR opts or Ubuntu binutils' strings defaults differ from macOS, splitting/stripping the route literal in ways grep doesn't see. Cargo's JSON output IS the canonical truth. If cargo says the feature is enabled, it IS enabled — the post-build sanity check should not override that with a heuristic. Three changes: 1. Drop the 'strings die' entirely — it produced wrong-failure on a correctly-built binary, blocking the deploy AFTER cargo had already confirmed success. 2. Replace with a 'nm' symbol-table check (more reliable than strings; symbols are link-time evidence the function is compiled in). But keep it WARN-only: if nm doesn't see the symbols on this rustc version either, that's a diagnostic signal, not a stop signal. 3. probe_or_die post-restart is the canonical runtime gate. If the binary really lacks the feature, the broker BOOT_FAILs with 'unknown auth method' and probe_or_die catches it within 20s with the journal output. So we lose nothing by trusting cargo here. Tested locally: - nm sees 5+ email-link symbols on macOS - cargo JSON assertion still fires on bad builds - probe_or_die remains the runtime safety net The user can now re-pull + re-run setup-broker-host.sh and the build phase will succeed (because cargo's truth is trusted). If the binary is actually broken, probe_or_die catches it post-restart with full journal output. * fix(setup-broker-host): incremental builds by default; clean only when needed User feedback: 'cargo clean -p' on every re-deploy adds 3-5min full rebuild — too slow for the common case where the cache is fine. New behavior: Default (no flag): incremental build, no clean. Assert via cargo's JSON output that auth-email-link is enabled. If the assertion misses, SELF-HEAL by running 'cargo clean -p' + rebuild ONCE. Failing the retry is a real environment bug (host config override, env var pin) and dies with diagnostics. → Fast path: ~10-30s on warm cache. --clean Force 'cargo clean -p' upfront before the build. Use after a feature flag flip when you KNOW cargo's cache will mislead. → 3-5min full rebuild. --no-clean Never clean; trust incremental cache. Disable self-heal too — die immediately on assertion miss. Use in CI / unattended re-deploys where you want hermetic, fast, fail-loud behavior. Also: the assertion now treats 'cargo emitted no compiler-artifact' (incremental cache hit, nothing to rebuild) as a PASS rather than a fail. Without the artifact line cargo is saying 'binary on disk is unchanged from last build' — that's fine, because last build was either also under this script's control (with the assertion) or the assertion will trigger the rebuild path. Refactored into two helpers (build_broker_with_features + assert_feature_enabled) to make the auto/--clean/--no-clean dispatch readable. Verified locally: - default mode + warm cache: artifact emitted, features reported, assertion passes (~instant) - --clean: clean + rebuild + assertion passes - --no-clean: assertion-only, no retry on miss * fix(setup-broker-host): when cargo cache-hits, verify binary exists on disk Edge case: if a previous build completed successfully, then someone manually 'rm target/release/agentkeys-broker-server' (e.g. trying to force a rebuild), cargo's incremental cache says 'nothing changed' and emits no compiler-artifact line. The previous logic treated that as a pass and proceeded to install — which then failed with 'install: cannot stat /path: No such file or directory' instead of something actionable. Add a one-liner: when ENABLED_FEATURES is empty (no artifact line), check that the binary actually exists at the expected path. If not, return 1 so the self-heal path kicks in (cargo clean -p + rebuild). Cheap (-x test, ~ms) and shores up the only remaining hole in the incremental-build trust model. * docs(cloud-setup,stage7): grant ses:SendEmail to broker-host role for SES v2 Pass-2 broker (auth-email-link) hits AccessDeniedException at runtime because the broker calls 'ses SendEmail' (SES v2 API) with its OWN instance-profile credentials, but cloud-setup.md only granted SES permission to the per-user-assumed agentkeys-data-role. Two layered fixes: 1. cloud-setup.md §3.4 (agentkeys-broker-host instance profile): add a second put-role-policy call attaching 'BrokerSendEmail' with ses:SendEmail on both the domain identity and any per-address identity at that domain. The runbook had only sts:AssumeRole on this role, which was sufficient pre-Pass-2 but not anymore. 2. stage7-demo-and-verification.md §0.4 prereqs: add a troubleshooting block for the exact error string the operator sees: 'broker rejected /v1/auth/email/request: status=502 body={"error":"backend_unreachable", "message":"... ses SendEmail: unhandled error (AccessDeniedException)"}' with the one-shot fix command + explanation of WHY ses:SendEmail (not ses:SendRawEmail — different IAM action for sesv1 vs sesv2). The IAM update propagates ~instantly; no broker restart needed (sesv2 picks up creds per-call). Per CLAUDE.md runbook-fix-fold-back: every operator-encountered failure makes the runbook strictly more robust before we move on. * fix(cloud-setup,stage7): grant ses:SendEmail with role discovery, not hardcoded name Applied ses:SendEmail to the broker's actual runtime role (S3-full-access — discovered via 'aws ec2 describe-instances' on the live broker host). The existing docs assumed the canonical role name 'agentkeys-broker-host' from §3.4 fresh setup, but legacy deploys (this one included) use an ad-hoc legacy name from initial provisioning that predates the broker. Two doc changes: 1. cloud-setup.md — moved the SES grant out of §3.4 (where it was wrong: §3.4 is a clean-slate role-creation block, and operators running through it would get the grant for the wrong reasons). Added new §3.4a 'ses:SendEmail grant on the broker's runtime role (Pass 2 prereq)' with explicit two-step flow: Step 1: discover the actual role attached via the broker's EC2 IP ROLE=$(aws ec2 describe-instances --filters Name=ip-address,...) ROLE=$(aws iam get-instance-profile --instance-profile-name "$ROLE" ...) Step 2: aws iam put-role-policy --role-name "$ROLE" --policy-name BrokerSendEmail Both steps reference $ROLE (variable, set by discovery), NOT a hardcoded role name. Includes the verify command operators should run after. 2. stage7-demo-and-verification.md §0.4 troubleshooting block — updated to use the discovery-then-grant pattern instead of hardcoding 'agentkeys-broker-host'. Cross-links to §3.4a for the full flow. Verified end-to-end: ran the discovery + grant against the live broker host (i-0c0b739bd35643fd3 / S3-full-access role, elastic IP 54.164.117.252). The inline policy 'BrokerSendEmail' now grants ses:SendEmail on: - arn:aws:ses:us-east-1:429071895007:identity/bots.litentry.org - arn:aws:ses:us-east-1:429071895007:identity/*@bots.litentry.org No broker restart needed — sesv2 picks up the grant per-call. * feat(demo): auto-click magic-link helper + least-privilege broker IAM Two related fixes addressing the user-encountered blocker (CLI polls forever because alice@demo.example is RFC 2606 example domain — no inbox to click from): 1. NEW scripts/agentkeys-init-email-demo.sh — fully automated demo: • Picks demo-1@bots.litentry.org or demo-2@... by parity of unix epoch seconds (so consecutive runs don't collide on the broker's single-use token TTL). • Snapshots existing inbound/ keys BEFORE SendEmail so we only inspect arrivals NEW to this run (vs scanning 400+ stale objects). • Spawns 'agentkeys init --email' in background; polls S3 for the magic-link email; QP-decodes the body to extract '$OIDC_ISSUER/auth/email/landing#t='. • Lifts the token out of the URL fragment and POSTs {token: } to /v1/auth/email/verify — replicating exactly what the browser-side JS in /auth/email/landing does (curling the landing URL alone wouldn't work; fragments don't ride in HTTP requests). • Cleans up the consumed S3 object on success. • Waits for agentkeys init to complete; dumps log + dies on timeout. Includes preflight that rejects wrong AWS profile (agentkey-broker user lacks ListBucket). 2. cloud-setup.md §3.4a: • Step 2: grant now includes BOTH ses:SendEmail (per-request) AND ses:GetEmailIdentity (verify_sender_ready startup probe). Previously the broker BOOT_FAILED on GetEmailIdentity for any fresh deploy with this section's recommended grant. • NEW Step 3 'security audit': explicit warning + commands to detach AmazonS3FullAccess and similar over-broad managed policies. The broker process at runtime ONLY uses aws-sdk-sts + aws-sdk-sesv2; per-user S3 access is via JWT-assumed agentkeys-data-role, NEVER via the broker's runtime role. A compromised broker with S3FullAccess could read every magic link in the inbound bucket. 3. stage7-demo-and-verification.md §0.4: replaced 'agentkeys init --email alice@demo.example' (undeliverable) with the new auto-click helper as the RECOMMENDED path; kept manual alternative for operators with a real inbox they control. Explicit warning to not use example.com / demo.example. Live broker IAM (i-0c0b739bd35643fd3, role 'S3-full-access'): • Inline 'BrokerSendEmail': ses:SendEmail + ses:GetEmailIdentity on identity/bots.litentry.org + identity/*@bots.litentry.org • Detached: AmazonS3FullAccess (was: full read/write on all account buckets, including the verification-token bucket) • Final state: 1 inline policy, 0 attached policies, all least- privilege. The script's auto-click flow is also a useful regression-test loop — the user wanted '1 or 2 emails for test' so we can drive a full auth round-trip without a human in the loop. * fix(demo): fast-fail in poll loop when agentkeys init dies early The polling loop waited the full 2-min budget for an email that would never arrive if 'agentkeys init' had already exited (broker rejection, signer unauthorized, etc.). Add a 'kill -0 $init_pid' check at the top of each iteration: if init is gone, dump its log and die. Cuts the failure-mode latency from 2 min to ~5s and surfaces the actual error from init's stdout/stderr. * fix(demo): die loud if invoked under sudo (env vars get stripped) User hit: 'REGION env var required (source operator-workstation.env)' even after sourcing the env file. Root cause: they ran the script with sudo, which (per most distros' default sudoers) strips env to PATH/USER/HOME/TERM/MAIL only — REGION/MAIL_DOMAIN/MAIL_BUCKET/ OIDC_ISSUER/BACKEND_URL all vanish in the child process and the script dies on the first ${VAR:?...} guard. The script doesn't need root: AWS calls use the operator's profile (in shell env), and 'agentkeys init' writes the session JWT to the USER's OS keychain. Running under sudo would actually break things even if env was preserved (keychain lookup would target root's keychain, not the operator's). Two changes: 1. scripts/agentkeys-init-email-demo.sh: detect SUDO_USER at start and die loud with the exact re-run command, before the cryptic env-var guard fires. 2. docs/stage7-demo-and-verification.md \xc2\xa70.4: explicit 'Do NOT prefix sudo' note next to the recommended invocation, explaining why (env stripping + wrong keychain). * fix(demo): O(1) hash-set membership for new-key detection (was always-true) Bug: 'aws --output text' returns keys TAB-separated. The previous substring check 'case " $pre_keys " in *" $k "*' looked for SPACE-surrounded matches, so every key in current_keys missed and every poll attempt reported all 415+ pre-existing keys as 'new'. Functionally correct (the per-key body grep still narrows down to the magic-link email) but ~415 needless 'aws s3 cp' calls per attempt — slow. Fix: build a bash associative array (pre_set[$k]=1) at snapshot time. O(1) membership check per key in the polling loop. Switch new_keys from a space-separated string to a proper array so it works regardless of key contents. Verified locally: bash -n syntax ok; empty-array iteration safe under 'set -euo pipefail' (declare -a + "${new_keys[@]}"). * fix(demo): bash-3.2 compat — drop declare -A (macOS /bin/bash freeze) User error: 'declare: -A: invalid option'. macOS ships /bin/bash 3.2 forever (Apple GPLv3 freeze) and the script's shebang resolves there. 'declare -A' (associative arrays) requires bash 4+. Replace the associative-array set with a string-based set: PRE_KEYS_SET=' $pre_keys_text ' # leading + trailing spaces case "$PRE_KEYS_SET" in *" $k "*) continue ;; esac Bash-3.2 compatible. SES-generated S3 keys are alphanumeric (no spaces), so the space delimiter is exact-match safe. 'tr \t \ ' normalizes the tab-separated 'aws --output text' output upfront. Verified locally under /bin/bash 3.2.57: - syntax check passes - isolated dry-run: 5 pre-existing keys, 1 new arrival → set difference correctly returns just the new key Indexed arrays + array+= and "${arr[@]}" iteration are bash 3.1+, so the rest of the script (new_keys array) still works. * fix(demo): operator precedence — '|| true | tr' parsed wrong, tr never ran on success Bash precedence: '|' binds tighter than '||'. So cmd1 2>/dev/null || true | tr '\t' ' ' parses as cmd1 2>/dev/null || (true | tr '\t' ' ') meaning tr ONLY runs if aws fails. On success (the common path) pre_keys_text remained tab-separated, the case-pattern '*" $k "*' looked for space-surrounded matches, every key missed, every poll attempt reported all 417 keys as 'new'. The earlier '/bin/bash isolated dry-run' didn't reproduce because it used a different invocation form (printf piped to tr) that wasn't subject to this precedence trap. Fix: group with braces so the pipe gets the output of either branch: Verified live against the actual 417-object inbound bucket under /bin/bash 3.2.57: - pre_keys_text now space-separated (no tabs detected) - same-list comparison correctly returns 0 new keys * fix(init_flow): thread session JWT to signer derive + SIWE sign calls Magic-link demo (scripts/agentkeys-init-email-demo.sh) was failing after the broker accepted the click ({"ok":true}) but before returning the derived wallet. The error was 'signer error: unauthorized: missing Authorization: Bearer header'. Root cause: in crates/agentkeys-core/src/init_flow.rs, two HTTP signer calls used HttpSignerClient::new() WITHOUT chaining .with_session_jwt(): - derive_via_signer (line 261): creates client without JWT, /dev/derive-address fails 401 - siwe_round_trip (line 314): creates client without JWT, /dev/sign-message fails 401 The standalone agentkeys signer derive / signer sign CLI commands DO chain .with_session_jwt(session.token) from the keychain (lib.rs:1169), but the in-flow init_via_email_link path also has the identity-session JWT in hand (just minted by the broker after the magic-link click), so it just needs to be threaded through. Fixed both call sites + added #[allow(clippy::too_many_arguments)] on finish_init (which was already at 8 args — pre-existing clippy warning that surfaced after the audit). Doc fold-back: stage7-demo-and-verification.md §3 'Mint OIDC JWT for STS' previously assumed $SESSION_JWT_A was already populated, but the §2.0 path ('agentkeys init --email') leaves the JWT in the keychain or file fallback with no CLI extraction wrapper. Added explicit instructions for both \§2.0 (file fallback / macOS Keychain) and \§2.1-2.4 (manual SIWE response capture) paths. Self-check (all 5 steps green against live broker.litentry.org): 1. agentkeys signer derive → 0x885904faf3d5624a30b0427078015d0072f604ea 2. agentkeys signer sign → 132-char sig 3. broker /healthz → 200 4. /v1/mint-oidc-jwt → 692-char OIDC JWT with correct aws.amazon.com/tags claims 5. AssumeRoleWithWebIdentity → assumed-role/agentkeys-data-role/... Stage 7 demo flow validated end-to-end through §4.1 (STS exchange). §4.2-4.3 (S3 isolation probe) requires writing to the production bucket and is left to explicit operator authorization. * fix(demo): handle both literal '=' and QP-encoded '=3D' in URL extraction The broker's SES outbound mails are pure-ASCII so the parts are 7bit-encoded — the magic-link URL appears in the body with a LITERAL '=' between 't' and the base64url token: https://broker.litentry.org/auth/email/landing#t=Kwm1lO8z... The previous regex looked only for 't=3D' (QP-encoded form). It never matched on production emails, so the script timed out polling even though the email had arrived in S3. Fix: alternation '#t=(3D)?[A-Za-z0-9_-]+' matches both forms, then 'sed s/#t=3D/#t=/' normalizes to literal-'='. Verified by extracting against an actual stored email — token came out clean and POSTs to /v1/auth/email/verify succeed with {"ok":true}. * fix(docs+scripts): always pass --region "$REGION" — agentkeys-admin profile defaults to us-west-2 The agentkeys-admin local profile defaults to us-west-2 (verified via `aws --profile agentkeys-admin configure get region`), while every broker-side resource (EC2, S3 mail bucket, SES identity) lives in us-east-1. Without an explicit `--region "$REGION"` on every regional AWS CLI call, the agentkeys-admin profile silently searches the wrong region — describe-instances returns empty (no error, exit 0), and the downstream `iam put-role-policy --role-name ""` silently no-ops. Real symptom (this session): operator ran the §0.4 ROLE discovery snippet under awsp agentkeys-admin → ROLE came back empty → SES grant never landed. Diagnosis took two rounds because there's no stderr signal. Changes: - CLAUDE.md: new "AWS local-profile ↔ remote-IAM mapping" section documenting (a) the three-profile table, (b) the per-profile region divergence trap (agentkeys-admin=us-west-2, others=us-east-1), and (c) case-insensitive caller-arn matching since the remote IAM user is agentKeys-admin (capital K) vs local agentkeys-admin (lowercase). - docs/stage7-demo-and-verification.md §0.4: ROLE discovery now passes --region "$REGION" + fail-loud guard on empty INSTANCE_PROFILE_ARN. Plus 5x s3api lines (§4.2 + §16) gain --region. - docs/cloud-setup.md §3.4a: ROLE discovery rewritten with --region + fail-loud guard. Plus 5x s3api lines (bucket-policy + lifecycle + delete-bucket + access-block) gain --region. - scripts/inspect-inbound-email.sh: require REGION up-front (loud-fail guard); pass --region "$REGION" on all 4 aws calls. - scripts/ses-verify-sender.sh: case-insensitive caller-arn match (`tr [:upper:] [:lower:]` — portable to /bin/bash 3.2) so agentKeys-admin (capital K) no longer triggers the bogus "caller is not agentkeys-admin" warning. Verified end-to-end under AWS_PROFILE=agentkeys-admin (profile region us-west-2): ROLE discovery now returns S3-full-access correctly; inspect-inbound-email.sh runs cleanly; ses-verify-sender.sh no longer emits the spurious warning. Co-Authored-By: Claude Opus 4.7 (1M context) * docs: drop legacy "S3-full-access" framing — broker role rename completed in prod Production broker EC2 (i-0c0b739bd35643fd3) was migrated 2026-05-12 from legacy `S3-full-access` instance profile to canonical `agentkeys-broker-host`. Migration steps executed: 1. Created `agentkeys-broker-host` role + instance profile via `aws iam create-role` + `create-instance-profile` (matches cloud-setup.md §3.4 conventions). 2. Attached complete `BrokerSendEmail` inline policy on new role: `ses:SendEmail` AND `ses:GetEmailIdentity` (the latter folds in the perm gap that prevented `verify_sender_ready` from succeeding). 3. Atomically swapped EC2 instance profile via `aws ec2 replace-iam-instance-profile-association` (no creds gap). 4. Verified broker /healthz=200 + sent two test emails through the new role (HTTP 200, request_id eml-bf4e..., eml-2aff...). 5. Cleaned up legacy artifacts: removed role from old profile, deleted inline policy + role + instance profile, revoked the temporary `ec2:Describe/ReplaceIamInstanceProfileAssociations` grant on `agentKeys-admin` IAM user. Doc updates: - cloud-setup.md §3.4a: drops "may use ad-hoc S3-full-access from initial provisioning" framing — fully retired. Discovery snippet retained because it's robust against any future drift. - stage7-demo-and-verification.md §0.4 troubleshooting block: same. Drops the `legacy/fresh` distinction that no longer applies. Known follow-up (separate scope, spawned task): `/readyz` still returns 503 with "SES verification cache absent at /var/lib/agentkeys/.agentkeys/broker/ses-verify.json" — this is a pre-existing bug independent of IAM. Production code never calls `verify_sender_ready()` and never invokes `SesVerifyCache::save()`, so the cache file is never populated. The IAM permission is now in place (this commit's `agentkeys-broker-host` role has `ses:GetEmailIdentity`), so once the boot path wires `verify_sender_ready()` + `cache.save()` /readyz will turn green. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(broker): wire SES sender-verify probe to populate readiness cache The email-link plug-in's `Readiness::ready()` reads `SesVerifyCache` from disk and reports `auth/email_link: SES verification cache absent` when the file is missing. No production code path called `verify_sender_ready()` or `SesVerifyCache::save()`, so /readyz was permanently 503-degraded on this check even when SES was configured correctly and email-link auth worked end-to-end. Add a Tier-2 probe spawned alongside the existing backend probe: calls `sender.verify_sender_ready()`, writes the cache on success, flips `Tier2State::ses_verified`. Exponential backoff up to 5min on failure (non-blocking; honors BROKER_REFUSE_TO_BOOT_STRICT). After a success, re-verifies every 12h so the cache stays well under the plug-in's 24h freshness TTL. * docs(stage7 §0.4): canonicalize on agentkeys-broker-host + fold in GetEmailIdentity grant + 722a990 verify-probe note §0.4 troubleshooting block updated for the post-rename world: - Lead with the canonical role: "Broker IAM role: `agentkeys-broker-host`" (was: "the role name varies by deployment ... legacy may use S3-full-access"). - Document the **complete** BrokerSendEmail policy: BOTH `ses:SendEmail` AND `ses:GetEmailIdentity`. Previously the grant snippet only granted SendEmail; the missing GetEmailIdentity perm was why /readyz reported `auth/email_link: SES verification cache absent` even when SES was working. Both actions now in the put-role-policy snippet AND in the copy-paste verify command (`aws iam get-role-policy ...`). - Reframe AccessDeniedException troubleshooting: from "find the unknown role name" → "verify it's still agentkeys-broker-host (defensive against future drift)". The discovery snippet stays — robust against future instance-profile churn — but the verify expected output now references the canonical name explicitly. - Add the restart-needed nuance for the verify probe: SendEmail picks up creds per-call (no restart needed), but the Tier-2 verify probe (commit 722a990) runs once at boot then every 12h, so adding GetEmailIdentity requires a broker restart for /readyz to reflect it. Production verified: `aws iam get-role-policy ... BrokerSendEmail` returns `[["ses:SendEmail","ses:GetEmailIdentity"]]` exactly as the doc claims. Co-Authored-By: Claude Opus 4.7 (1M context) * docs(stage7 §0.3/§0.4): make demo work with strict JWT-omni signer + Keychain-free CLI Two operator-blocking traps surfaced while walking §0.4 against the live broker; both fixed end-to-end. Trap 1: signer rejects derive with "JWT omni_account claim does not match request body". §0.4 used to call `signer derive --omni-account $OMNI_A` where `$OMNI_A = sha("agentkeys","email","alice@demo.example")` from §0.3 — but the session JWT minted by `agentkeys-init-email-demo.sh` is for `demo-1@bots.litentry.org` (or demo-2 on rotation). After issue #74 step 1b's strict JWT-omni check, the signer requires `JWT.omni_account == request.omni_account` exactly. The arbitrary alice/bob omni never matches. Fix: - §0.3 reframed as "math reference only" — the helper recomputes the broker's omni formula so the operator can verify the algorithm, but the actual `OMNI_A` / `OMNI_B` come from the live session JWTs in §0.4 below. - §0.4 adds a `decode_jwt_payload()` helper that pulls `agentkeys.omni_account` and `agentkeys.wallet_address` directly from `~/.agentkeys/master/session.json` (no signature verify — just base64-decoding the body for our local read). - For the §4 isolation proof we now run `init-email-demo.sh` TWICE (the script's epoch-parity rotation between demo-1 and demo-2 gives two distinct sessions automatically; consecutive runs naturally yield two distinct (omni, wallet) pairs). - Drops the wrong `ADDR_A == JWT.wallet_address` assertion. The signer derive returns the EVM-omni's wallet (post-SIWE-promoted identity), which is a *different* keypair from the email-omni's wallet stored in `JWT.agentkeys.wallet_address`. Both are real, both are derived by the same signer; they play different roles in the demo (the JWT's wallet_address was the SIWE signing key that bootstrapped the session; ADDR_A is the EVM-identity wallet used downstream for S3 path scoping). Trap 2: even with matching omni, `agentkeys signer derive` returned `SIGNER_UNAUTHORIZED: invalid session JWT: InvalidToken` while a raw `curl` with the same JWT succeeded. Root cause: the CLI defaults to `KeyringMode::Auto` (crates/agentkeys-core/src/session_store.rs:86) — Keychain first, file fallback. A stale Keychain entry from earlier dev runs gets picked up and fed to the signer, which rejects the signature. The user-visible symptom is also keychain access prompts on every CLI call. Fix: - `scripts/operator-workstation.env` exports `AGENTKEYS_SESSION_STORE=file`, which forces `KeyringMode::FileOnly`. The demo is now Keychain-free end-to-end. Comment explains the trade-off (fresh-machine users can comment the line out to re-enable Keychain). - §0.4 callout block documents the trap + the raw-curl fallback so an operator can self-diagnose "is it the JWT or the CLI?" in one step. End-to-end verified under AWS_PROFILE=agentkeys-admin with the new env: OMNI_A extracted from session.json's JWT decodes to `402d4bac…`; `agentkeys --json signer derive --omni-account $OMNI_A` returns `0xcd936bf34d3156e84cd2e479e267cf39d15a85a6` (HTTP 200, no Keychain prompts). Co-Authored-By: Claude Opus 4.7 (1M context) * feat(stage7): multi-tenant --session-id + one-shot demo-show.sh + §0.4 key-topology rewrite User pain (during §0.4 walk-through): 1. Each `init-email-demo.sh` run overwrites ~/.agentkeys/master/session.json, so back-to-back inits for the §4 two-actor isolation proof can't coexist. 2. §0.4 forced operators to hand-decode the JWT in 6 lines of awk+base64 just to learn OMNI / ADDR — once per session, twice per demo, no rich output. 3. The OMNI_B / ADDR_B / identity-omni / derived-wallet / evm-omni terminology was opaque: §0.4 didn't reconcile its own vars with `architecture.md` §3+§4 (K3/K4, identity omni vs actor omni), so the operator couldn't tell which wallet AWS actually sees at the PrincipalTag step in §4. Changes: - crates/agentkeys-cli: top-level `--session-id` flag (env AGENTKEYS_SESSION_ID), plumbed through CommandContext to session_store. Defaults to "master" so existing behavior is preserved. `with_session_id` ignores empty strings to keep a forgotten `AGENTKEYS_SESSION_ID=` shell-export from silently writing to ~/.agentkeys//session.json. - scripts/agentkeys-init-email-demo.sh: accepts `--session-id ` flag and exports AGENTKEYS_SESSION_ID so the background `agentkeys init` writes under ~/.agentkeys//. Two back-to-back runs with distinct ids leave both sessions live for the §4 proof — no need to re-init to switch. Auto- invokes scripts/agentkeys-demo-show.sh at the end so the operator sees the (omni, wallet) pair without a follow-up command. - scripts/agentkeys-demo-show.sh (new): one-shot rich-output inspector. Reads ~/.agentkeys//session.json, decodes the JWT body, prints • identity (type, value, locally-recomputed identity_omni) • actor (actor_omni, master_wallet) • signer-wire smoke test (HKDF(K3, actor_omni) — a SECOND wallet, flagged NOT-used-for-AWS in the output) • JWT TTL remaining Supports --json, --no-derive, and positional session-id. Bash-3.2 portable (no `${var,,}`, no `mapfile`, jq+awk+base64 only). - docs/stage7-demo-and-verification.md §0.3: corrected the "both omnis end up in the JWT's `agentkeys` claim" line — the FINAL JWT carries only the EVM actor omni (the identity-omni is transient and consumed at SIWE-verify). Cross-linked the truth to crates/agentkeys-broker-server/src/handlers/auth/ wallet_verify.rs:51. - docs/stage7-demo-and-verification.md §0.4: new "Key topology" subsection that names the three wallets the demo conflates today — identity_omni → SHA256("agentkeys"||"email"||email), transient, NOT in JWT MASTER_WALLET → HKDF(K3, identity_omni_email), the SIWE-linked wallet, JWT.wallet_address ADDR (= W2) → HKDF(K3, actor_omni), what §2's SIWE round-trip uses and what §4's S3 isolation actually tags via §2.3's fresh JWT Both wallets are real, signable, and deterministic; §2.2's `signer sign` only works for ADDR because the strict JWT-omni check forces the signed omni to match the JWT's actor_omni. Updated the §0.4 capture block to use the new demo-show.sh JSON output for both OMNI_A/ADDR_A and an explicit MASTER_WALLET_A side-channel for cross-reference. Cross-linked crates/agentkeys-broker-server/src/handlers/oidc.rs:106 (the line that decides which wallet AWS sees). End-to-end verified locally: bash scripts/agentkeys-demo-show.sh --no-derive master → rich text bash scripts/agentkeys-demo-show.sh --no-derive --json master → JSON shape bash scripts/agentkeys-demo-show.sh --no-derive nonexistent → loud fail cargo run -p agentkeys-cli -- --help | grep session-id → exposed AGENTKEYS_SESSION_ID=alice cargo run -p agentkeys-cli -- --help → env wired cargo test -p agentkeys-cli --lib → green * fix(stage7): preflight stale-binary loud + fold install-check into §0 prereqs User hit a silent-failure trap walking §0.4 today: ran `bash scripts/agentkeys-init-email-demo.sh --session-id alice`, the script reported success ("Initialized via email-link..."), but the session landed at ~/.agentkeys/master/session.json instead of ~/.agentkeys/alice/session.json — and demo-show.sh then failed with "no session file at ~/.agentkeys/alice/session.json". Root cause: the `agentkeys` binary on $PATH was built before today (2026-05-12). The `--session-id` flag (and its env=AGENTKEYS_SESSION_ID binding) is a clap declaration in the binary — an older binary silently ignores the env var, falls back to the hardcoded "master" default, and writes to ~/.agentkeys/master/. Diagnose-before-edit verified by: command -v agentkeys → /Users//.local/bin/agentkeys (May 11 21:01) agentkeys --help | grep session-id → empty (no flag) ls -la ~/.agentkeys/master/session.json → freshly written ls ~/.agentkeys/alice/ → no such directory Fix lands in THREE places (per runbook-fix-fold-back): 1. scripts/agentkeys-init-email-demo.sh — preflight that `agentkeys --help` exposes `--session-id`. Dies loud with the exact rebuild command (`cargo install --path crates/agentkeys-cli --force`) and the verify-after command. Catches the trap BEFORE the script burns 2 minutes polling for an email + writing to the wrong session-id. 2. scripts/agentkeys-demo-show.sh — same capability check inside the signer-derive branch. Without it, a stale binary feeding the wrong --session-id to `signer derive` would silently re-derive against the master session's omni, masking the real diagnosis. 3. docs/stage7-demo-and-verification.md §0 prereqs — step 6 after the existing `agentkeys --version` check that re-runs the same grep and dies if absent. Folds the diagnosis inline so the next operator catches the stale binary at the moment they're already looking at install output — no need to discover the trap by watching init-email-demo.sh "succeed" first. Verified locally: REGION=u MAIL_DOMAIN=t MAIL_BUCKET=t OIDC_ISSUER=https://t BACKEND_URL=https://t \ bash scripts/agentkeys-init-email-demo.sh --session-id alice → "stale 'agentkeys' binary at /Users/agent-jojo/.local/bin/agentkeys — missing --session-id flag. Rebuild + reinstall from this worktree: cargo install --path crates/agentkeys-cli --force" → exit 1 (no S3 polling, no SES SendEmail) * fix(stage7): unique recipient per --session-id + show SHA256 inputs + --export mode Three operator-blockers landed today walking §0.4: 1. `--session-id alice` and `--session-id bob` produced the SAME wallet because the legacy default recipient rotated demo-1/demo-2 by epoch parity — two back-to-back runs hit the same parity, got the same recipient, derived the same identity_omni (HKDF deterministic), thus the same MASTER_WALLET. The §4 isolation proof becomes vacuous (same actor → same prefix → trivially "allowed both reads"; demo doesn't prove anything). 2. The `init-email-demo.sh` log + demo-show.sh output named the identity_omni hex but did NOT show the SHA256 inputs (type, value), so the operator couldn't reproduce the math by hand or diagnose why two different sessions collided. 3. §0.4 had three `jq -r` extractions per session to pull OMNI / ADDR / MASTER_WALLET out of `--json` — 6 lines for two sessions, with the field paths hand-typed and easy to mis-name. The doc + the show script weren't a single source of truth. Fixes: - scripts/agentkeys-init-email-demo.sh — new recipient precedence: $RECIPIENT > positional arg > $SESSION_ID-derived (when not "master") > legacy demo-1/demo-2 rotation. With `--session-id alice` the recipient is now alice@$MAIL_DOMAIN deterministically, NOT a rotating demo-N. The log now prints the computed identity_omni and the SHA256 formula inline so collisions are visible BEFORE SES SendEmail fires. - scripts/agentkeys-demo-show.sh — new `--export ` mode emits eval-able shell assignments: SESSION_ID_

=… OMNI_

=… ADDR_

=… MASTER_WALLET_

=… IDENTITY_TYPE_

=… IDENTITY_VALUE_

=… IDENTITY_OMNI_

=… so the doc / an operator script can capture all seven fields with one `eval "$(bash scripts/agentkeys-demo-show.sh --export A alice)"`. Values are `printf %q`-escaped — survives eval with arbitrary content. The human-readable output now shows the full `= SHA256("agentkeys" || "" || "")` formula under the identity_omni line so the math is reproducible at a glance. - docs/stage7-demo-and-verification.md §0.4 — replaced the 12-line `--json | jq -r` extraction block with two `eval` calls + a new collision-diagnostic that explains exactly why MASTER_WALLET_A == MASTER_WALLET_B can happen (same recipient → same identity_omni) and what the fix is. Verified locally: eval "$(bash scripts/agentkeys-demo-show.sh --no-derive --export A master)" echo "$OMNI_A $IDENTITY_OMNI_A $MASTER_WALLET_A $IDENTITY_TYPE_A $IDENTITY_VALUE_A" → all seven vars populated, identity values match what shasum -a 256 computes bash scripts/agentkeys-init-email-demo.sh --session-id alice → Recipient: alice@bots.litentry.org (not demo-N) → identity_omni (email) = dbcb6acd... (visible BEFORE SendEmail) Why this is the fix and not a workaround: HKDF(K3, omni) is the contractual signer derive — same omni in, same wallet out is the WHOLE point of the deterministic-derive design. The bug was the demo's recipient rotation, NOT the signer. Two operators with literally the same email address WILL get the same wallet, by design. The fix guarantees each --session-id maps to a distinct recipient so the §4 proof actually exercises two distinct actors. * docs(stage7 §0.4): doc the deterministic recipient + --export modes; comments → prose Three improvements requested after the user walked the just-shipped multi-tenant flow: 1. The "Run two distinct sessions" block still claimed `--session-id alice → ~/.agentkeys/alice/, demo-1 or demo-2` from the pre-fix behavior. With the 2026-05-13 recipient-derivation fix, `--session-id alice` deterministically uses `alice@bots.litentry.org` (and bob → bob@bots.litentry.org). Doc now states this explicitly + shows the first 5 log lines where `Recipient`, `identity_omni (email)`, and the SHA256 formula are visible — making collisions diagnosable BEFORE the SES SendEmail fires. 2. The §0.4 bash blocks were carrying ~50 lines of inline shell comments that re-explained context already covered in prose. Moved the explanations OUT of the bash blocks into prose paragraphs above each block, keeping the runnable snippets small and copy-paste-friendly. The `=== ON OPERATOR WORKSTATION ===` location markers stay (consistent with the rest of the doc). 3. `agentkeys-demo-show.sh --export ` was barely mentioned. Now has: - A "modes" table covering the three output formats (default human / `--json` / `--export `) with the "use when" column. - A dedicated `#### Capture (OMNI, ADDR) pairs for §2 + §4 via --export` subsection explaining the two-eval pattern and why it's idempotent. - A per-session vars table (7 vars: SESSION_ID, OMNI, ADDR, MASTER_WALLET, IDENTITY_TYPE, IDENTITY_VALUE, IDENTITY_OMNI) with their source claim in the JWT and what each is used for downstream. - Documented the `--no-derive` and positional `` adjuster flags. No script-side changes — the script's behavior was already correct in the 2026-05-13 commit; this commit just brings the doc into agreement. * docs(stage7 §2): fold-back AGENTKEYS_SESSION_ID stickiness + §14.8 ExpiredSignature Operator ran `init-email-demo.sh --session-id alice` (writes to ~/.agentkeys/alice/session.json, fresh JWT) then hit §2.2's `agentkeys signer sign --omni-account $OMNI_A` and got SIGNER_UNAUTHORIZED: invalid session JWT: ExpiredSignature. Root cause: the CLI's `--session-id` flag defaults to "master" when neither `--session-id` nor `AGENTKEYS_SESSION_ID` is set, so the bare `signer sign` call read ~/.agentkeys/master/session.json — a ~12h-stale session from May 12. `--export A alice` emits shell vars (OMNI_A, ADDR_A, …) but does NOT route follow-up CLI calls. Fold the fix back into the doc per runbook-fix-fold-back policy: 1. §0.4 — after `eval --export A/B`, add `export AGENTKEYS_SESSION_ID="$SESSION_ID_A"` so the rest of §2 reads the right session. 2. §2.0 (recommended path) — thread `agentkeys --session-id alice init …` and explain that §2.1–§2.5 need either the flag or the env-var pinned. 3. §2.4 (bob block) — retarget with `export AGENTKEYS_SESSION_ID="$SESSION_ID_B"` before the bob SIWE round-trip. 4. §14.8 — new troubleshooting entry walks the operator through diagnose (decode both JWT exps, see which one was used) → fix (export the right session-id) → re-init if even alice's JWT is stale (ttl is 5h). 5. §16.4 — live walkthrough's "point at signer.litentry.org" block now also pins AGENTKEYS_SESSION_ID with a cross-ref to §14.8. No code changes — the CLI behavior was already correct (default to master is intentional for single-tenant users). This commit teaches the multi-tenant operator how to wire `--session-id` through every follow-up call in the demo. * docs(stage7): make every section multi-tenant aware Audit pass — every `agentkeys` / `agentkeys-daemon` invocation in docs/stage7-demo-and-verification.md now either passes `--session-id ` explicitly or inherits an explicit `AGENTKEYS_SESSION_ID=` set earlier in its section. Previously several sites silently defaulted to `--session-id master`, which is the trap commit 930c58c addressed in §2 and §14.8. This commit extends the same wiring across §0, §2.5, §3, §8, §9, and §16.7 so the whole walkthrough is consistent. Changes: - §0 (build + init intro): replace "run `agentkeys init` once" with "run `agentkeys --session-id init` once per tenant", and upfront-warn that the demo runs both `alice` and `bob` side-by-side so every CLI call needs session-id wiring. - §2.5 `agentkeys whoami`: add inheritance-from-§0.4 prose + a retarget example for `bob` (`agentkeys --session-id "$SESSION_ID_B" whoami`). - §3 SESSION_JWT_A extraction: replace hardcoded `~/.agentkeys/master/session.json` with `~/.agentkeys/$SESSION_ID_A/session.json`, and the Keychain lookup's `-a master` → `-a "$SESSION_ID_A"`. Add a swap-for-bob note. - §8 email-link manual entry: `agentkeys signer derive` → `agentkeys --session-id alice signer derive`; add caveat that step 3's JWT must be persisted to ~/.agentkeys/alice/session.json or inlined as Authorization: Bearer. - §9 OAuth2 manual entry: same treatment. - §16.7 auto-provision: `agentkeys init …` → `agentkeys --session-id alice init …`; add `export AGENTKEYS_SESSION_ID=alice` before `agentkeys provision openrouter` so the subprocess inherits. - §16.7 daemon variant: `agentkeys-daemon …` → `agentkeys-daemon --session-id alice …`; add prose explaining the daemon's `--session-id` mirrors the CLI's. No code changes — the CLI + daemon already support `--session-id` since 398e0e4a / e9cf0097. This commit only teaches the doc to use it consistently end-to-end. * docs(stage7 §2): make automation-vs-manual path explicit + warn against overwriting §0.4 Operator question: "§2 still requires a manual magic-link click — can I reuse init-email-demo.sh to automate it?" Answer is yes; that's exactly what §0.4's `init-email-demo.sh --session-id alice` already does. But the doc didn't surface this clearly: 1. §2 intro didn't tell readers that §0.4's script IS the §2 automation. 2. §2.0 used `--email alice@demo.example` (RFC 2606 placeholder) which silently OVERWRITES the §0.4 session with a different identity_omni_email → different MASTER_WALLET → different actor_omni. Shell vars from §0.4's `--export A alice` then mismatch alice's new JWT, and §2.2 strict JWT-omni check fails. Fold-back: - §2 intro: new "Two ways to drive this section" table that calls out `init-email-demo.sh` (default), manual `agentkeys init --email` (when you want a real inbox click), and §2.1–§2.5 (manual SIWE walkthrough, redundant after §0.4 or §2.0 — read for understanding). - §2.0: lead with "Already done by §0.4 if you ran `init-email-demo.sh --session-id alice`" callout. Replace the `alice@demo.example` placeholder with `` so the example can't be copy-pasted into a chain-overwriting bug. Add explicit "Don't substitute a placeholder email when you've already run the script" warning explaining the JWT-omni mismatch. Surface `init-email-demo.sh --session-id alice` as the automated equivalent of the manual form. No code changes. The script behavior was already correct; this commit teaches the doc to explain the relationship between §0.4 and §2 so the next operator doesn't accidentally re-init alice with a placeholder. * fix(stage7): init-email-demo prints eval hint; §14.4 covers ADDRESS DRIFT from stale shell vars Operator hit `ADDRESS DRIFT — master secret rotated mid-session?` at the end of §2.2 after running `init-email-demo.sh --session-id alice` twice in succession (or once after a previous --export against a different session). Root cause: the script can't `export` shell vars from its subshell, so $ADDR_A / $OMNI_A in the parent shell carry whatever was last captured by `eval --export A …` — usually stale. The §2.2 sanity check `[[ "$SIG_ADDR" == "$ADDR_A" ]]` compares the just-now signer-returned address against shell `$ADDR_A`, sees the mismatch, and prints ADDRESS DRIFT — a confusing message since K3 didn't actually rotate. Two fixes land together (runbook-fix-fold-back): 1. `scripts/agentkeys-init-email-demo.sh` — after the demo-show human-mode block, print a prominent "Next: capture eval-able shell vars" hint with the exact `eval` command tailored to the session-id: - alice → prefix `A`, bob → `B`, master → `M`, otherwise uppercase-session-id - the hint also lists the 7 vars that get populated and warns about the ADDRESS DRIFT failure mode if skipped 2. `docs/stage7-demo-and-verification.md` — two callouts: - §2.0: pair every `init-email-demo.sh --session-id ` mention with the matching `eval … --export` line + an explanatory aside on why a subprocess can't set parent-shell vars - §14.4: extend the existing "signature does not recover" entry to also cover `ADDRESS DRIFT` (same family of causes), with a 5-line diagnostic recipe + a 5-row table mapping symptom → cause → fix (stale $OMNI_A, stale $ADDR_A, $ADDR_A=master_wallet mixup, real K3 rotation, SIWE message mutation) Stale shell vars are by far the most common cause in practice; real K3 rotation only happens when setup-broker-host.sh --force rebuilds the env file. The doc now ranks them in that order. * docs(stage7 §2.4): explicit eval --export B bob requirement + 401 cross-ref Same stale-shell-vars trap as §2.2, this time hitting §2.4. Operator ran `init-email-demo.sh --session-id bob` (bob's session is fresh) but then went straight into §2.4's curl block without running the `eval --export B bob` line the script printed as its end-of-run hint. §2.4 previously only retargeted `AGENTKEYS_SESSION_ID="$SESSION_ID_B"`, which assumes `$SESSION_ID_B` was already populated by a prior `--export B bob` somewhere. When that's not true, `$ADDR_B`/`$OMNI_B` come from a previous shell session (or are unset/different identity), the SIWE message claims a stale address, signer signs HKDF(K3, stale-$OMNI_B) which doesn't recover to it, and broker returns: HTTP 401 — signature does not recover to claimed address Fix in §2.4: make the eval line the FIRST step of the subsection, with a cross-ref to §14.4's 5-row symptom→cause→fix table for operators hitting the 401 directly. Call out the script's own hint and that the eval is idempotent (re-run after every fresh init). No script changes — the script already prints the eval hint correctly. This commit just makes the doc not assume the operator scrolled back to run it. * docs(stage7 §3): collapse to 3 blocks, lead with the §2.3-completed path §3 was 65 lines and led with a two-path "Populating SESSION_JWT_A" explanation that confused operators who'd just done §2 step-by-step. For them `$SESSION_JWT_A` is already set from §2.3's VERIFY response — no extraction needed. Rewrite: 1. Lead with: "§2.3 already set $SESSION_JWT_A — mint OIDC JWT" → one curl block. 2. Decode + check the `aws.amazon.com/tags` claim → one jq pipeline. 3. TTL warning (5 min) → one line. 4. Collapsed-into-callout fallback for the operator who skipped §2.1–§2.4 and only ran the init script (reads $SESSION_JWT_A from ~/.agentkeys//session.json or Keychain). Trims §3 from 71 → 28 lines (-43 net) and puts the §2-step-by-step operator on the happy path without explanatory detours. * fix(stage7 §3): broken base64-pad form silently produced empty output The §3 decode pipeline I introduced in 9e119c9 used a printf-with- format-recycle pattern: printf '%s=%.0s' "$p" $(seq 1 $pad) That doesn't do what I assumed. With seq giving "1 2", printf recycles the format and emits: %s consumes $p → body = → literal %.0s consumes "1" → nothing %s consumes "2" → "2" = → literal So the body got a stray "2=" appended (or similar per pad count), base64 -d errored on the malformed string, 2>/dev/null swallowed the diagnostic, and the user saw an empty prompt with no jq output. Switch §3 to the same `head -c` truncation idiom §14.8 and §16.4 already use (verified working): printf '%s%s' "$p" "$(printf '====' | head -c $pad)" | base64 -d Verified against a synthesized test JWT with the AWS tags claim — the new pipeline emits the expected {aud, sub, tags} jq selection. * docs: terminology-source-of-truth rule + canonical-names table in arch.md Operator hit confusion between `agentkeys whoami` printing "session_wallet:" and the OIDC JWT decode showing "agentkeys_user_wallet" — both refer to the same field (`JWT.agentkeys.wallet_address` = master_wallet per arch.md §3 row K4 + §3-line-372), but the doc + CLI spelled it three different ways. Two changes, no code: 1. CLAUDE.md — extend "Architecture-as-source-of-truth policy" with a "Terminology-source-of-truth rule" subsection. Rule: never invent a new name for a concept arch.md already names. When a divergence is discovered (e.g. `session_wallet` in CLI vs `agentkeys_user_wallet` in OIDC vs `master_wallet` in arch.md), either align the call site or document the alias in arch.md's canonical-names table — never silent drift. Drift must be auditable. 2. arch.md — new §3a "Canonical names" table. Maps every concept to ONE canonical name + every alias seen in code/docs/demo today. Covers: master_wallet, derived_address(omni), actor_omni, identity_omni, K3/master_secret, session JWT, OIDC JWT. Top callout pins the most-confused pair: master_wallet (persisted, AWS sees it) vs derived_address(actor_omni) (recomputed on demand, never reaches AWS). The CLI's `session_wallet:` output label in `agentkeys whoami` is now an alias-row entry in §3a — a follow-up could rename it to `master_wallet:` to match arch.md, but the audit table at least makes the equivalence discoverable in one read. The stage7 demo doc's §4 also claims AWS sees `ADDR_A` (= `derived_address(actor_omni)`) in PrincipalTag, which contradicts the broker code at `crates/agentkeys-broker-server/src/handlers/oidc.rs:106` where the OIDC claim comes from `session_claims.agentkeys.wallet_address` (= master_wallet). That's a real bug; fixing it is a separate pass. * docs(stage7): align terminology with arch.md §3a canonical names Three sections rewritten to bridge demo shell-var names (OMNI_A, ADDR_A, MASTER_WALLET_A) to arch.md §3a canonical names (actor_omni, derived_address(actor_omni), master_wallet). Shell vars stay unchanged — they're embedded across the doc + scripts — but every prose / table / callout now names the arch.md concept too, so an operator reading whoami output, §3's OIDC decode, or arch.md can resolve "is this the same thing" in one read. Changes: 1. §0.4 "Key topology" — table now has both columns ("Demo shell var" + "arch.md §3a canonical name"). The "Which wallet ends up in AWS PrincipalTag?" callout names BOTH the §2 manual path (OIDC stamps derived_address(actor_omni) = ADDR_A) and the §0.4-only path (OIDC stamps master_wallet = MASTER_WALLET_A) so operators using either approach know what to expect. 2. §2.5 whoami — output comments now annotate each line with its arch.md canonical name. New table maps the three printed labels: - session_wallet (CLI) ↔ master_wallet (arch.md) - omni_account (CLI) ↔ actor_omni (arch.md) - derived_address (CLI) ↔ derived_address(actor_omni) (arch.md) Closing note that session_wallet (from disk) and the OIDC's agentkeys_user_wallet (from §2.3's fresh JWT) can resolve to different values when the §2 manual path is walked. 3. §4 intro + 4b explanation — names the wallet shape as arch.md `derived_address(actor_omni)` and tells operators following the §0.4-only path to substitute MASTER_WALLET_A. No code changes. No shell-var renames. The demo's bash blocks stay copy-paste compatible. Per CLAUDE.md "Terminology-source-of-truth rule" — arch.md §3a is the source; this commit aligns the consumer doc to it without silent drift. * fix(stage7 §4.2): aws s3api put-object --body /dev/null fails on macOS AWS CLI's --body parameter expects a seekable regular file path. macOS rejects /dev/null with `ParamValidation: Blob values must be a path to a file` (character device, not a regular file). Linux's CLI sometimes accepts it, which is why the doc was never caught. Replace with `EMPTY=$(mktemp) && trap 'rm -f "$EMPTY"' EXIT` — creates a real zero-byte regular file, preserves the §4.3 comment's expected `ContentLength: 0` response, cleans up on shell exit. * fix(cloud-setup §4.4): bucket policy was missing bots/ parent prefix cloud-setup.md §4.4 deployed bucket policy as Resource: bucket/${tag}/* and s3:prefix: ${tag}/*, putting per-actor wallets at the bucket root alongside SES's inbound/ landing zone. arch.md §6's sequence diagram shows bots/A/file — the canonical shape is bots//<...>. Operator hit AccessDenied at stage7 §4.3 because the demo's bots/${ADDR_A}/ keys didn't match the policy's bare ${tag}/* condition. First attempt at a fix dropped bots/ from the demo to match the deployed policy; operator pushed back — at scale this mixes user data with system prefixes and breaks lifecycle/replication/audit scoping. Right answer per CLAUDE.md "Architecture-as-source-of-truth": align the policy to arch.md, not the other way around. Changes: - cloud-setup.md §4.4: bucket policy now grants ListBucket conditioned on s3:prefix LIKE bots/${tag}/* and GetObject on bucket/bots/${tag}/*. Added prose explaining bots/ as the per-actor data namespace (sibling to inbound/, future audit/, dkim/, etc.). - stage7 demo §4: reverted the earlier "drop bots/" pass. §4.2 seeds + §4.3 reads + §5.1 ls + §16.6 live walkthrough all back to bots/${ADDR_A}/... shape. §0.4 callout reverted to bots/$ADDR_A/. - ses-email-architecture.md §10.3, §10.4: policy JSON + storage path table updated to bots///.eml so the arch.md → cloud-setup.md → ses-email-arch.md chain reads consistently. No code changes (bucket policy is applied manually per cloud-setup.md §4.4; no auto-deploy script needed an update). Operators with an already-deployed bucket need to re-apply the policy once — the command is the same `aws s3api put-bucket-policy` block from cloud-setup.md §4.4, re-run with admin profile. * fix(stage7 §3+§4): pin SESSION_JWT_A source; use $WALLET_FOR_S3 in §4 Operator hit AccessDenied at §4.3 because $JWT_A carried agentkeys_user_wallet=$MASTER_WALLET_A (sourced from on-disk init JWT) but §4 commands listed bots/$ADDR_A/. Two different wallets — policy denied because PrincipalTag expanded to bots/$MASTER_WALLET_A/* and the list prefix was bots/$ADDR_A/. Root cause: §3 had two sources for $SESSION_JWT_A (§2.3 VERIFY response vs ~/.agentkeys//session.json) without making the precedence explicit. If you ran §2.3 AND then re-read from disk (thinking it was a "freshness refresh"), the on-disk value silently shadowed the §2.3 one and AWS saw $MASTER_WALLET_A instead of $ADDR_A. Fold-back: - §3 head: new "$SESSION_JWT_A precedence" callout table — two sources, two different wallets, pick ONE and commit to which. - §3: immediately after mint-oidc-jwt, decode JWT_A and capture $WALLET_FOR_S3 = jwt.agentkeys_user_wallet. Echoed inline so the operator can see which path their JWT actually represents. - §4 intro: tell operators to use $WALLET_FOR_S3 throughout, NOT bare $ADDR_A or $MASTER_WALLET_A. - §4.2 seed: introduce $OTHER_WALLET (= path-matched peer for the §4b deny target). Seeds use ${WALLET_FOR_S3} and ${OTHER_WALLET}. - §4.3 list/get: ${ADDR_A} → ${WALLET_FOR_S3}; ${ADDR_B} → ${OTHER_WALLET}. - §4b explanation: refer to $WALLET_FOR_S3 / $OTHER_WALLET instead of the path-specific names. No code changes. The demo now copy-pastes correctly for both paths (§2-manual and §0.4-only) without per-path mental substitution. * docs(stage7 §3+§4): clean single-path test — mint both JWTs, decode wallets, prove isolation Previous version branched §4's S3 prefix on which §2 path operators took — referenced $ADDR_A vs $MASTER_WALLET_A and required an if-statement to pick the right one. Caused the AccessDenied trap operators kept hitting (mismatch between what JWT_A carried and what their list-prefix used). Clean rewrite: §3 mints OIDC for BOTH tenants and decodes $WALLET_A / $WALLET_B from each JWT's agentkeys_user_wallet claim. §4 uses those decoded variables directly — no conditional, no "depends on path" prose. Whichever wallet the broker stamped into each session JWT IS the wallet S3 gates on, and §3 captures it verbatim. Changes: §3: - Two mint-oidc-jwt calls (alice + bob) up front. - decode_aws_wallet() helper → $WALLET_A, $WALLET_B. - Single sanity decode of $JWT_A's tags claim. - Footnote: where $WALLET_A points to depends on which $SESSION_JWT_A source you used; both are valid because §4 reads the decoded value directly, not the source name. - "Skipped §2 entirely?" callout simplified to two-line jq reads from disk for both alice and bob. §4: - §4.1: drop the redundant `aws sts get-caller-identity` (moved to §4.3 where it actually matters — after re-exporting assumed-role creds). - §4.2: seeds use $WALLET_A / $WALLET_B directly. No more $OTHER_WALLET selector or if-statement. - §4.3: list/get use $WALLET_A (own) / $WALLET_B (peer). Identity check moves here. - §4b explanation: names $WALLET_A and $WALLET_B by their semantic role (alice's / bob's), not by path. §16.4–§16.6 unchanged — that walkthrough is the §2-manual path end-to-end and uses $ADDR_A consistently. * feat(stage7): one-shot isolation-demo script + doc §4.0 Add scripts/agentkeys-isolation-demo.sh — the executable form of stage7 §3 + §4. Picks up where init-email-demo.sh leaves off: 1. Auto-runs init-email-demo.sh for alice + bob if their sessions aren't on disk (configurable via --reinit-* flags). 2. Loads SESSION_JWT_A/B from ~/.agentkeys//session.json (with macOS Keychain fallback for AGENTKEYS_SESSION_STORE=keychain). 3. Mints OIDC JWTs for both. 4. Decodes WALLET_A/B from each JWT's agentkeys_user_wallet claim — same value regardless of which §2 path the operator took, so the script is pre-merged across the manual-SIWE and §0.4-only paths. 5. Assumes agentkeys-data-role via JWT_A. 6. Seeds bots/$WALLET_A/hello.txt + bots/$WALLET_B/hello.txt via admin profile (admin bypasses bucket policy via account ownership). 7. Asserts probe 4a: alice can read bots/$WALLET_A/ → SUCCESS. 8. Asserts probe 4b: alice DENIED on bots/$WALLET_B/ → AccessDenied. Exit codes: 0 isolation proof PASSED 1 precondition missing (env, tools, sessions) 2 false-negative — alice can't read own prefix (bucket policy / role inline issue) 3 false-positive — ISOLATION BROKEN, §4.4.1 strip didn't run Doc §4.0 added — leads with the one-shot script, then §4.1–§4.3 remain as the manual wire-by-wire breakdown for understanding. The script is the canonical demo command for CI / unattended verification runs; the manual sections stay for debugging + pedagogy. No code/policy changes — the script is a thin orchestrator over existing init-email-demo.sh + standard curl/aws CLI calls. Exit codes let CI distinguish "isolation works" from "isolation broken" from "setup wasn't right". * fix(isolation-demo): AWS_PROFILE=empty broke assume-role; clearer step logs Operator saw: aws: [ERROR]: The config profile () could not be found after step 4. Root cause: `AWS_PROFILE= aws sts assume-role-...` sets AWS_PROFILE to the empty string for the subshell, and the AWS CLI parses that as a profile name "" — not as "no profile". Fix: unset AWS_PROFILE properly before the assume-role call. Same trap doesn't apply to the seed step because `AWS_PROFILE=agentkeys-admin aws s3api ...` sets a real profile name. After the assume-role call, re-unset AWS_PROFILE before re-exporting env creds so the SDK doesn't prefer the named profile over the env. Also refined the log format. Old script mixed `==>` info and `✓` success markers inline, making it hard to scan for "did step N finish": ==> alice session on disk ✓ loaded session JWTs for alice + bob New format groups each step under a `═══ [N/7]` header with indented substeps, and the two probes get explicit PROBE 4a / PROBE 4b banners showing what we asked AWS + what we expected + what came back: ═══ [1/7] Sessions on disk alice: /Users/.../session.json exists (pass --reinit-alice to force fresh) ✓ alice session ready ... ═══ [7/7] Probe both prefixes under assumed-role creds operating as: arn:aws:sts::.../assumed-role/.../isolation-demo-A-... PROBE 4a list bots// (expect ALLOW) → 1 key(s) returned ✓ alice ALLOWED on own prefix PROBE 4b get bots//hello.txt (expect DENY) → AccessDenied (as expected) ✓ alice DENIED on peer prefix — cloud-enforced isolation works Additional improvements: - JWT expiry is decoded and printed next to each session/OIDC JWT, so operators see at a glance whether a JWT is about to expire. - The 4b probe captures the AWS error message and explicitly confirms it's AccessDenied (vs some other transport error pretending to be isolation working). - Failure paths print the actual AWS response next to the diagnostic so operators don't have to re-run with -v to see what AWS said. * fix(isolation-demo): address codex adversarial-review P1/P2/P3 findings Codex flagged 6 correctness bugs (P1), 7 hardcoded values (P2), and 4 robustness gaps (P3). All fixed in this commit. The previous script could print "isolation proof PASSED" while isolation wasn't actually proven — most importantly because L214's peer-probe accepted any non-success error (ExpiredToken, NoSuchBucket, network failure) as a valid AccessDenied. Fixes: P1#1 — Peer-probe (4b) now strict-matches the literal "AccessDenied" substring in the AWS error. Any other failure (ExpiredToken, SignatureDoesNotMatch, NoSuchBucket, network) dies with the upstream cause printed, so an environmental failure can't masquerade as cloud-enforced isolation. P1#2 — Own-prefix proof (4a) now does BOTH list-objects AND get-object, and asserts the seed key appears in the list response. A list-only policy can no longer pass as a full isolation proof. P1#3 — Admin head-object pre-confirms each seed landed before the proof runs. Combined with a per-run unique probe key (`probe--.txt`), an AccessDenied at probe time can no longer be confused with "object never existed". P1#4 — JWT decode now reads .agentkeys_user_wallet AND ."https://aws.amazon.com/tags".principal_tags.agentkeys_user_wallet[0] and dies if they diverge. Guards against a future broker bug that mutates only one of the two claims. P1#5 — Both WALLET_A and WALLET_B validated for null + EVM-address format (0x + 40 lowercase hex). WALLET_B=null can no longer drive a fake probe at bots/null/. P1#6 — Mirror direction runs by default: bob assumes role, reads bob's prefix (ALLOW), denied on alice's (DENY). Both directions of the isolation invariant are now proven. Can be disabled via --skip-mirror. P2#1 — DATA_ROLE_ARN env override; role name parsed from the ARN for the caller-identity sanity check (no longer hardcoded). P2#2 — Session reuse logic checks BOTH ~/.agentkeys//session.json AND the macOS Keychain marker — Keychain-backed sessions no longer silently skip the reuse path. P2#3 — ALICE_SESSION_ID / BOB_SESSION_ID env + --alice-id / --bob-id flags; "alice" / "bob" are defaults, not hardcoded identifiers. P2#4 — Role-session-name now includes RUN_TAG (nanoseconds + PID), so concurrent operators don't collide in STS or CloudTrail audit. P2#5 — ADMIN_AWS_PROFILE env override. P2#6 — BOT_PREFIX env override; probe key is per-run unique. P2#7 — Probe download paths via mktemp; cleanup trap removes them. P3#1 — AWS env scrubbed at script entry (line 1), before init-email-demo.sh inherits any stale creds. P3#2 — Bob's seed put-object now has the same `|| die` diagnostic path as alice's. P3#3 — Cleanup trap on EXIT deletes seeded objects + tmp downloads (skip with --keep-seeds). P3#4 — Session JWTs validated at load time: non-null .token and three-segment-JWT format check, before any downstream curl can fail with a confusing error. New exit codes (was 4, now 6): 0 proof passed 1 precondition missing 2 false negative (alice can't read own prefix) 3 false positive — ISOLATION BROKEN 4 pre-probe seed missing (admin head-object failed after put) 5 JWT claim divergence (agentkeys_user_wallet ≠ tags claim) Codex review reference: full P1/P2/P3 findings in chat transcript (commit 113a5cd era of the script). * fix(stage7 §5): WALLET_A from JWT decode + §5.2 reframe + §5.3 CLI path + arch.md terminology §5.1: load $SESSION_JWT_A from disk/Keychain + decode $WALLET_A from the freshly minted OIDC JWT. Fixes silent AccessDenied on the auto-init path (where SESSION_JWT_A.wallet_address = master_wallet ≠ ADDR_A, making the old `bots/${ADDR_A}/` prefix deny). Verified end-to-end against live broker.litentry.org — STS returns creds, s3 ls succeeds. §5.2: rewritten as a non-curl reference. Empirically confirmed the curl example was unreachable from the auto-init path: the per-call signature must recover to `master_wallet` (claims.agentkeys.wallet_address), but the signer's strict JWT-omni check only signs with `actor_omni` which recovers to `derived_address(actor_omni) = ADDR_A ≠ master_wallet`. Section now points at tests/mint_v2_flow.rs for the working test-fixture canonical-body + EIP-191 pattern, and clarifies that operators should use §5.1 (client-side) or §5.3 (CLI) for end-to-end demos. §5.3: replaced broken `agentkeys-daemon --session $JWT` (which exits immediately with `wallet=local` because session.rs:6 builds a placeholder session and no --stdio is configured) with `agentkeys provision ` (cli/main.rs:200). Added prereq `npm install + playwright install chromium` so operators don't hit `Cannot find package 'playwright'`. Added note: `trip_wire_fired` from a stale scraper IS proof the pipeline worked (scraper subprocess only ran because AWS creds were minted + injected). §16.5/§16.6: same JWT-decode pattern → $WALLET_A everywhere. §6/§7/§8/§10/§16.4: arch.md §3a canonical names threaded through (daemon_address = derived_address(actor_omni), identity_omni vs actor_omni vs master_wallet vs derived_address). Per CLAUDE.md terminology-source-of-truth rule. scrapers/openrouter.ts: added KNOWN BROKEN banner linking issue #83 (label: provision-fix) so anyone reading the source sees the DOM-drift flag inline, separate from the still-working auto-provision pipeline. * docs(stage7 §5.3): add full fresh-start sequence (auto-init → provision) Replaces the partial 2-block §5.3 with a single self-contained fresh-start path: init-email-demo.sh → demo-show export → load session JWT → mint OIDC → AssumeRoleWithWebIdentity → provision. Matches the actual sequence verified end-to-end on 2026-05-15 (tripwire fires from openrouter scraper — proves the auto-provision pipeline works, scraper-DOM drift tracked in #83). Operators can now copy-paste §5.3 from a clean shell to reproduce the live broker demo without piecing together prereqs from §0-§5.1. --------- Co-authored-by: wildmeta-agent Co-authored-by: Claude Opus 4.7 (1M context) --- CLAUDE.md | 65 + Cargo.lock | 217 +- crates/agentkeys-broker-server/Cargo.toml | 16 +- crates/agentkeys-broker-server/src/boot.rs | 77 +- crates/agentkeys-broker-server/src/env.rs | 13 +- .../src/jwt/session.rs | 14 +- crates/agentkeys-broker-server/src/main.rs | 123 +- .../src/plugins/auth/email_link.rs | 243 +- .../src/plugins/auth/mod.rs | 4 +- .../tests/email_flow.rs | 1 - .../tests/ses_email_flow.rs | 410 ++++ crates/agentkeys-cli/Cargo.toml | 2 +- crates/agentkeys-cli/src/lib.rs | 342 ++- crates/agentkeys-cli/src/main.rs | 154 +- crates/agentkeys-cli/tests/cli_tests.rs | 20 +- crates/agentkeys-core/Cargo.toml | 7 + crates/agentkeys-core/src/init_flow.rs | 437 ++++ crates/agentkeys-core/src/lib.rs | 2 + crates/agentkeys-core/src/signer_client.rs | 285 +++ .../tests/signer_conformance.rs | 329 +++ crates/agentkeys-daemon/src/main.rs | 152 +- crates/agentkeys-mock-server/Cargo.toml | 10 + .../src/dev_key_service.rs | 410 ++++ .../src/handlers/dev_keys.rs | 191 ++ .../agentkeys-mock-server/src/handlers/mod.rs | 1 + crates/agentkeys-mock-server/src/lib.rs | 21 +- crates/agentkeys-mock-server/src/main.rs | 108 +- crates/agentkeys-mock-server/src/state.rs | 29 + .../tests/dev_key_service_routes.rs | 468 ++++ docs/archived/README.md | 3 + .../contradictions-stage4-2026-04.md} | 0 docs/{ => archived}/field-name-translation.md | 0 .../operator-runbook-pre-stage7.md} | 0 .../stage7-wip-pre-arch-rewrite.md} | 4 +- docs/cloud-setup.md | 223 +- docs/dev-setup.md | 6 +- docs/spec/architecture.md | 986 +++++--- .../heima-gaps-vs-desired-architecture.md | 205 +- .../plans/issue-74-dev-key-service-plan.md | 45 + .../plans/issue-74-step-1c-device-key-auth.md | 487 ++++ docs/spec/ses-email-architecture.md | 8 +- docs/spec/signer-protocol.md | 236 ++ docs/spec/threat-model-key-custody.md | 2 +- docs/stage7-demo-and-verification.md | 2058 ++++++++++++++--- hardcoded.md | 99 + harness/stage-5a-live-demo-handoff.sh | 18 +- .../src/scrapers/openrouter.ts | 9 + scripts/agentkeys-demo-show.sh | 209 ++ scripts/agentkeys-init-email-demo.sh | 410 ++++ scripts/agentkeys-isolation-demo.sh | 391 ++++ scripts/broker.env | 56 +- scripts/inspect-inbound-email.sh | 9 +- scripts/install-agentkeys-cli.sh | 188 ++ scripts/operator-workstation.env | 64 + scripts/ses-verify-sender.sh | 213 ++ scripts/setup-broker-host.sh | 529 ++++- 56 files changed, 9641 insertions(+), 968 deletions(-) create mode 100644 crates/agentkeys-broker-server/tests/ses_email_flow.rs create mode 100644 crates/agentkeys-core/src/init_flow.rs create mode 100644 crates/agentkeys-core/src/signer_client.rs create mode 100644 crates/agentkeys-core/tests/signer_conformance.rs create mode 100644 crates/agentkeys-mock-server/src/dev_key_service.rs create mode 100644 crates/agentkeys-mock-server/src/handlers/dev_keys.rs create mode 100644 crates/agentkeys-mock-server/tests/dev_key_service_routes.rs rename docs/{contradictions.md => archived/contradictions-stage4-2026-04.md} (100%) rename docs/{ => archived}/field-name-translation.md (100%) rename docs/{operator-runbook.md => archived/operator-runbook-pre-stage7.md} (100%) rename docs/{stage7-wip.md => archived/stage7-wip-pre-arch-rewrite.md} (98%) create mode 100644 docs/spec/plans/issue-74-step-1c-device-key-auth.md create mode 100644 docs/spec/signer-protocol.md create mode 100644 hardcoded.md create mode 100755 scripts/agentkeys-demo-show.sh create mode 100755 scripts/agentkeys-init-email-demo.sh create mode 100755 scripts/agentkeys-isolation-demo.sh create mode 100755 scripts/install-agentkeys-cli.sh create mode 100755 scripts/ses-verify-sender.sh diff --git a/CLAUDE.md b/CLAUDE.md index ac81a22..9cea16e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -7,6 +7,14 @@ See `docs/spec/plans/development-stages.md` for the 8-stage build plan.

Global IAM calls (`aws iam`) are region-less and don't need the flag. + +### Caller-ARN matching in scripts must be case-insensitive +Lowercase the caller_arn before matching, since the remote IAM user is `agentKeys-admin` (capital K) but operator scripts canonicalize on `agentkeys-admin`.
