Summary

  • add an optional SHA-256 expected_token_hash guard to agent release requests and both SDKs
  • bind release dispatch, local cleanup, and completion atomically to the exact issued-token generation, immutable built-in provenance, active node binding, and current provider route
  • commit agent-hosted and node-hosted action acceptance as an exact action/route/attempt CAS before send, then pin accepted generations through action pruning, takeover, retry, drain, reconciliation, and timeout recovery
  • version the stricter registered node-action acceptance proof as v2 so rolling upgrades fail closed against owners that understand only v1
  • migrate historical registered-action deliveries conservatively: only open rows with an action FK and dispatch-attempt evidence are marked accepted
  • bind migration cancellation tombstones to invocation ID plus node/provider/name, conservatively match unknown historical provider ownership, and fail ambiguous ID-less same-tuple registrations closed until the replacement supplies its exact invocation ID
  • acquire finite registration capacity before durable identity writes with exact compensating rollback and preserved identity-conflict precedence

Latest regression proof

  • five must-fire tests spanning six findings failed on test-only head 2f6a6afabf2864b4d27283f5e0fb41737aed3656: agent-hosted acceptance durability, selective migration backfill, explicit tombstone tuple binding, immutable invocation-action matching, accepted-pruned timeout pinning, and ID-less same-tuple replacement isolation
  • the ID-less replacement defect was also isolated independently on that old product head: no fresh-register-without-id cancellation error was emitted, proving the stale worker bypassed the tombstone when a replacement reservation existed
  • two further P1 regressions failed on exact test-only head bbbe944616c5c35142af8c457c94309488d97fd6: an exact-ID worker for a canceled legacy spawn with NULL provider ownership was admitted; authorization captured for attempt 1 sent after the invocation returned to the identical tuple at attempt 2
  • the rolling-owner regression failed on exact test-only head c797a18fe90081ebc06930af8ad9ac0751dcbd46: the engine sent the stricter proof as v1, which the modeled legacy owner accepted without understanding the attempt generation
  • green proof rejects exact-ID and ID-less unknown-provider stale workers; rejects old attempt 1; accepts current attempt 2 exactly once; rejects its replay; and sends v2 so the modeled v1 owner fails closed with durable node_dispatch_unavailable
  • earlier deterministic red regressions cover stale release before dispatch and completion, takeover, replay, action shadowing, retry/drain/reconciliation, concurrent capability pruning and rebind, migration capacity accounting, exact reservation ownership, and nontransactional rollback

Verification

Exact product head 1850bcec9e364d346e7195f40614f95611077fad:

  • focused engine proof: 4 files / 109 tests
  • engine typecheck
  • full engine: 70 files / 792 tests
  • npm run lint: 13/13 tasks
  • npm test: 18/18 tasks
  • npm run build: 9/9 tasks
  • earlier unchanged SDK surface proof: TypeScript SDK 22 files / 441 tests; types 7 files / 209 tests; Rust SDK 103 tests plus 5 doc-tests; Rust library clippy clean

Exact PR head 75387fac829b10f81e533fd80f80a6c399252be7 adds only the updated trajectory proof record atop that product head; jq empty and git diff --check pass. Exact-head hosted checks and fresh reviews are required before merge.

Full cargo clippy --all-targets -- -D warnings still reports two pre-existing result_large_err warnings in untouched tests/parity.rs callbacks under Rust 1.94; the changed library target is clean.

The checked-in external E2E scripts currently fail independently because their WebSocket authentication contradicts the enforced stream contract. That proof-harness defect is isolated as #378 and is not modified here.

Closes #376

📝 Walkthrough

Walkthrough

Relaycast adds SHA-256 token-generation guards to agent releases, records invocation provenance, preserves exact spawn reservations, and protects registered-action dispatch across retries and pruning. SDKs, API definitions, migrations, tests, changelogs, and documentation are updated.

Changes

Generation-safe agent release and dispatch

Layer / File(s) Summary
Release contract and client integration
packages/types/..., packages/engine/src/routes/agent.ts, openapi.yaml, packages/sdk-*, README.md, CHANGELOG.md
Release requests accept expected_token_hash. Routes and SDKs serialize the guard. API definitions document 400 and 409 responses.
Invocation provenance and migration reconciliation
packages/engine/src/db/..., packages/engine/src/engine/action.ts, packages/engine/src/engine/node.ts
Invocation rows record provenance and provider acceptance. Migrations settle ambiguous legacy rows and release their reservations.
Generation-guarded release lifecycle
packages/engine/src/engine/action.ts, packages/engine/src/adapters/node/realtime.ts, packages/engine/src/ports/realtime.ts
Dispatch, socket authorization, replay, completion, and failure paths reject stale generations and preserve replacement agents.
Reservation ownership and retry safety
packages/engine/src/engine/node.ts, packages/engine/src/engine/nodeProvider.ts, packages/engine/src/__tests__/conformance/...
Registration claims matching reservations. Spawn validates names. Registered-action retries preserve accepted attempts and reject deleted identities. Tests cover these paths and related races.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to 57680

Poem

A rabbit guards the token bright,
And checks each release day and night.
Stale generations yield in peace,
While newer takeovers stay at ease.
Exact reservations hold their place,
And accepted actions keep their trace.

Fresh exact head: fd4208e84a45661a4dd58468e918ef879e2c57dc. The follow-up preserves 409 agent_release_generation_conflict for guarded non-deleting releases rejected by the final dispatch CAS; full engine 70/753, focused race tests, lint, and typecheck are green.

@khaliqgant: I found that the node completion path uses an atomic guarded write batch. I am verifying whether the final dispatch check prevents a token rotation in the interval between the database check and the node send.

@khaliqgant: I completed the focused re-review of exact head 99c31ea9d4b9298e43d6da0b726f1a20119467a8.

I found no issues in the requested areas.

  • The socket owner validates the invocation, token generation, provider, and active binding before it sends the release frame.
  • The in-process send path has no asynchronous gap between authorization and socket.send(...).
  • Guarded releases fail closed with 503 node_dispatch_unavailable when an adapter does not implement owner authorization.
  • A persisted agent_release_generation_conflict returns 409 for both the keyed initial request and its replay.
  • The focused tests cover the send-boundary rotation, adapter absence, and atomic node-completion conflict paths.
  • git diff --check reported no whitespace errors.

@khaliqgant I reviewed exact head 2951bcb435a578c4bfc35c4b9b62c4455857a052.

I found two issues in the pre-dispatch path.

  1. High — Guarded releases can still cross the send boundary after a takeover.
    packages/engine/src/engine/action.ts Line 2318 checks the token generation in the engine. Line 2386 then calls the generic sendToProvider. A remote or asynchronous NodeConnectionRegistry adapter can process a takeover after the database check and before its socket owner sends the frame. The replacement can then receive a stale guarded release.

    Move the release generation validation into an owner-authorized send operation. The socket owner must verify the invocation, token hash, provider, and active binding immediately before socket.send(...). Guarded releases must fail closed if an adapter cannot provide that operation.

  2. Medium — A final guarded dispatch conflict returns 503 for non-deleting releases.
    When Line 2333 detects the generation mismatch, it persists agent_release_generation_conflict. dispatchRelease then processes !dispatched.accepted at Line 1265. For delete_agent: false, it calls failClosed and returns 503 agent_host_unavailable instead of the required 409 agent_release_generation_conflict.

    Re-read the invocation error after a failed guarded dispatch. If the error is agent_release_generation_conflict, return 409 and preserve the replacement unchanged.

The guarded node-completion path uses runAtomicWrites(..., { requireAtomic: true }). It settles a generation or binding mismatch before the lifecycle writes. I found no additional race in that completion path.

Fresh exact head f1cc17167e57a6f35683f4acfacccd40b0cb319d. This head addresses every prior thread, including old-adapter fail-closed settlement, named-provider guarded drain, post-dispatch 409 replay, accepted-send completion races, OpenAPI 400, changelog reference, and exact trajectory provenance. Exact-head root lint, all workspace tests (engine 70/759), root build, and diff/worktree checks are green.

@khaliqgant I reviewed exact head f1cc17167e57a6f35683f4acfacccd40b0cb319d.

I found no issues.

The guarded release path now handles the prior findings:

  • The socket owner validates the invocation, token generation, provider, and active binding before it sends the release frame.
  • Guarded releases fail closed with 503 node_dispatch_unavailable if an adapter cannot enforce the generation proof.
  • A rejected guarded send persists its terminal error. It cannot fall back to local release cleanup.
  • An accepted send that completes before the engine dispatch stamp returns the durable terminal result.
  • Replayed guarded conflicts return 409 agent_release_generation_conflict.
  • Drained guarded releases retain the original named provider.
  • Guarded node completion uses an atomic write unit. It settles token-generation or binding conflicts before lifecycle mutations.
  • openapi.yaml documents the malformed-guard 400 response.
  • The trajectory record now lists the product commits, changed files, and verification provenance.

git diff --check reported no whitespace errors.

@khaliqgant I reviewed the complete changeset at exact head 324449911a6f1722d0b4017eb03549d2c3368fdc.

I found no new issues.

The final commit changes only .agentworkforce/trajectories/relay-1672/completed/2026-09/traj_rkgn69o1fbjc/trajectory.json. It appends integration commit 6aef2748c46a3401e5f1077cade3c32dcd10d332 to commits and sets _trace.endRef to the same commit. The trajectory provenance is consistent.

The final head retains the previously reviewed guarded-release completion, registered-action acceptance CAS, socket-owner authorization, accepted-attempt pinning, and migration-tombstone correlation behavior.

git diff --check reported no whitespace errors.

Please review fresh exact head 7e735f74fefda6de112df5dfe7523be75f3d8f0c. The two prior P1s now have exact red-to-green regressions. Focus on conservative NULL-provider tombstone matching and exact previously-unaccepted dispatch-attempt CAS, including one-delivery idempotency.

Please security-review fresh exact head 7e735f74fefda6de112df5dfe7523be75f3d8f0c. Verify a stale worker cannot escape a NULL-provider migration tombstone, stale authorization cannot bless a newer same-route attempt, and current authorization can deliver only once.

Please review the full changeset at exact head 7e735f74fefda6de112df5dfe7523be75f3d8f0c. Both fresh P1s are fixed with red-to-green tests; focused 4/108, engine 70/791, typecheck, root lint 13/13, test 18/18, and build 9/9 are green.

@khaliqgant I reviewed the complete changeset at exact head 7e735f74fefda6de112df5dfe7523be75f3d8f0c.

I found no new issues.

The registered-node authorization now carries dispatchAttempt. The socket-owner CAS requires that value to equal the current dispatchAttempts. It also requires providerAcceptedAttempt to differ from that attempt. A stale authorization cannot accept a newer attempt on the same node and provider tuple. A repeated current authorization cannot deliver a second frame.

The new regression verifies both conditions. Attempt 1 fails after the route returns at attempt 2. Attempt 2 delivers one frame. A second attempt-2 authorization fails.

Migration-tombstone matching now treats a NULL dispatchedProvider as unknown. It matches any provider only on the same node and agent-name tuple. The registration path rejects both exact-ID and ID-less stale registrations with spawn_invocation_canceled. An ID-less registration remains blocked when a replacement reservation exists. The replacement can register with its exact invocation ID.

The existing accepted-generation protections remain intact. An accepted action stays pinned through pruning, retry, timeout sweep, and completion.

git diff --check reported no whitespace errors. I did not run the test suite in this sandbox.

@khaliqgant I reviewed the complete changeset at exact head c33227fb2e41dd462e9a7e83dc4e92cba85dc18b.

I found no new issues.

Registered node-action dispatch now sends registered-node-action-v2. The proof includes the claimed dispatchAttempt.

The socket owner explicitly rejects registered-node-action-v1. An older owner cannot accept a proof that has no attempt generation.

The registered-node-action-v2 acceptance CAS requires the exact invocation, action identity, invocation action name, route, active action row, dispatched status, and current dispatchAttempts. A stale authorization cannot accept a later attempt after the route returns to the same node and provider.

The CAS also rejects an already accepted attempt. A repeated current authorization cannot send a second action.invoke frame.

The regressions cover stale attempt rejection, one-delivery behavior, legacy-owner fail-closed behavior, pruning before authorization, and consistent action_deleted results for the request and keyed replay.

Migration-tombstone correlation remains fail-closed. A legacy tombstone with NULL dispatchedProvider matches any provider only when the node and agent-name tuple also match.

git diff --check reported no whitespace errors. I did not run the test suite in this sandbox.

@codex review

Please review final exact head 75387fac829b10f81e533fd80f80a6c399252be7. The only delta after the no-issue code review is trajectory provenance: summary and trajectory JSON now have identical ordered attributed commit sets.

@codex security review

Please security-review final exact head 75387fac829b10f81e533fd80f80a6c399252be7. Product code is unchanged from c33227f; the final delta only aligns trajectory provenance.

Please review final exact head 75387fac829b10f81e533fd80f80a6c399252be7. The final commit is provenance-only; ordered JSON and Markdown commit sets match exactly.

@khaliqgant I reviewed exact head 75387fac829b10f81e533fd80f80a6c399252be7.

I found no new issues.

The final commit changes only .agentworkforce/trajectories/relay-1672/completed/2026-09/traj_rkgn69o1fbjc/summary.md. It changes the attribution label and adds integration commit 6aef2748c46a3401e5f1077cade3c32dcd10d332.

The Markdown list and trajectory.json each contain 25 unique attributed commits. The lists have identical order and membership. The trajectory _trace.endRef remains 1850bcec9e364d346e7195f40614f95611077fad.

The final delta does not change product code. The previously reviewed generation guards, socket-owner authorization, accepted-attempt CAS, and migration-tombstone behavior remain unchanged.

git diff --check found no whitespace errors.
