feat: wire V10 Publishing Conviction NFT through SDK + daemon

[zsculac]

Summary

Wires the V10 DKGPublishingConvictionNFT write+read surface end-to-end through the SDK so operators can create, fund, and manage Publishing Conviction Accounts via the chain-adapter, the DKGAgent facade, and the daemon HTTP API. POST /api/pca and the funds/agent/settle routes now return 200 with real tx hashes instead of 503.

Closes #519. Sibling cleanup tracked in #520.

Stacked on #500 (feat/archive-non-v10-contracts) — base of this PR is that branch, not main. #519's "drop the V9 null stubs" only makes sense on top of #500's archive. #500 is still open (base main); rebase this onto main once #500 merges.

Why

The V10 PCA NFT contract is deployed and invoked by KnowledgeAssetsV10.publish() on-chain, but the SDK exposed only read shims — all PCA write methods returned null, so the daemon /api/pca/* routes returned HTTP 503. The V9 PublishingConvictionAccount predecessor was archived in #500. This PR closes the SDK gap (the follow-up ADR-0001 explicitly named).

What changed (transitive — every consumer in one PR, the #500 lesson)

• chain-adapter (packages/chain/src): new V10 interface surface — createConvictionAccount(committedTRAC), topUpConvictionAccount, registerConvictionAgent, deregisterConvictionAgent, isConvictionAgent, settleConvictionAccount, V10 12-tuple getConvictionAccountInfo. EVM impl + mock-adapter / no-chain-adapter parity. Dead V9 publishingConvictionAccount cache slot removed.
• DKGAgent facade (packages/agent/src/dkg-agent.ts): five return null PCA stubs deleted, delegate to the new adapter methods, lockEpochs dropped, key→agent terminology, callers fixed.
• daemon (packages/cli/src/daemon/routes/pca.ts): V10-shaped serializeAccountInfo; POST /api/pca body drops lockEpochs; :id/authorize replaced by POST :id/agent + DELETE :id/agent/:address; POST :id/settle added; :id/funds → topUp; owner revert → 403.
• api-client / CLI (packages/cli/src/api-client.ts): V10 request/response shapes; registerPcaAgent/deregisterPcaAgent/settlePca methods + commands.
• tests: packages/evm-module/test/v10-pca-lifecycle.test.ts (create → topUp → registerAgent → discounted publish via real KnowledgeAssetsV10.publish() → expiry revert); chain adapter + mock↔EVM parity; daemon route round-trip; devnet HTTP smoke.

V9 → V10 semantic break (DTOs changed shape — not a rename)

Concern	V9 (archived)	V10 (wired)
Lock duration	per-account lockEpochs arg	global protocol param; no caller arg
Authorization	authorizedKeys + admin	registerAgent + agentToAccountId (1 account/agent)
Ownership	admin field	ERC-721 ownerOf(accountId)
Funding	addFunds → balance	topUp → persistent topUpBalance
getAccountInfo	6-tuple	12-tuple (owner, committedTRAC, topUpBuffer, expiresAtEpoch, agentCount, …)

Breaking HTTP contract is acceptable: the V9 routes only ever returned 503 on V10 deployments — no working client to break. The same reasoning covers the ApiClient TypeScript surface (createPca drops lockEpochs; PCA probe field authorized→registered; method renames): an intentional, coordinated break for the 10.0.0-rc major — V9 is archived in stacked base #500, so a deprecated shim would only call a removed contract. Broader V9 SDK excision is tracked by #520.

Owner-gating (curation trust model)

createConvictionAccount mints to the signer; topUp/register/deregister are owner-only on chain (msg.sender == ownerOf(accountId)). The SDK surfaces the NotAccountOwner revert (not swallowed); the daemon maps it to 403 (distinct from 503 = no-chain). Agents publish only.

Verification

Built via 8 tracer-bullet slices (one commit-set each, TDD red→green, independent reviewer gating each slice — 37 commits). Reviewer caught and forced fixes for real defects, notably:

• mock↔EVM parity gaps (InvalidAmount/ZeroAgentAddress/baseEpochAllowance)
• api-client/CLI callers still V9-shaped (lockEpochs leak)
• lifecycle test used a Hub-rewired shortcut instead of real KnowledgeAssetsV10.publish()
• devnet smoke could pass on stale chain state — now force-boots a clean devnet and asserts 0 < discountedCost < baseCost on chain (guards the silent-demotion risk: KAv10 takes the discount branch only when publishEpochs == lockDurationEpochs)

Gates executed in-run (per slice, reviewer-gated): pnpm -r build; pnpm --filter @origintrail-official/dkg-chain test; pnpm --filter @origintrail-official/dkg-evm-module exec hardhat test; daemon route tests; clean-devnet HTTP /api/pca round-trip with on-chain discount assertion. CI (Tornado lanes) is the remaining gate this PR triggers.

Out of scope (followups)

• Excise V9 SDK scaffolding from chain-adapter / dkg-agent / daemon routes #520 — broader V9 SDK scaffolding excision (legacy ABIs, V9-touching evm-adapter methods, non-PCA interface cleanup).
• DKGStakingConvictionNFT SDK surface (createConviction/claim) — separate feature.
• On-chain Hub deregistration of V9 keys on existing deployments — ops task.
• V10-only reward-flywheel coverage test — separate add.

Post-review cleanup (2026-05-15)

Addressed reviewer feedback:

• Stripped non-feature artifacts (25ca4530): removed .devnet/run.mjs + pca-smoke-lib* and .scratch/issue-519/verify.md from the PR, reverted the .gitignore negation hack that force-tracked them, and added .scratch/ to .gitignore. The devnet smoke is verification scaffolding, not feature code — it runs locally; evidence lives here in the PR body. (Root cause: the orchestrator test_command was cd .devnet && node run.mjs, which forced the harness into the tree.)
• Trimmed oversized comments (1bd98146): pca.ts header 23→4 lines; chain-adapter.ts + dkg-agent.ts JSDoc condensed (−43 net comment lines). Kept the load-bearing why (owner-revert→403, no-chain→503); prose moved to ARCHITECTURE.md § #519.

Net PR diff is now packages/* (feature) + .gitignore (policy) + ARCHITECTURE.md only. pnpm -r build green.

Independent devnet runtime verification

Booted a clean 2-node devnet and drove the full operator path through the live daemon (not the in-run subagent — independently re-run end-to-end):

Step	Status	Detail
POST /api/pca	200	accountId=1 (V10 conviction NFT minted to daemon EOA)
POST /api/pca/:id/agent	200	3/3 publisher wallets registered
publish KC as agent	ok	kcId=1
publish signer bound	ok	publish signer is a registered agent of account 1
GET /api/pca/:id	200	agentCount=3, discountBps=5000, topUpBuffer=0
on-chain discount	ok	CostCovered emitted for account 1; discountedCost == baseCost·(10000−discountBps)/10000 (exact on-chain tier formula)

The CostCovered event firing from DKGPublishingConvictionNFT for the account proves the publish routed through coverPublishingCost (a demoted/direct-spend publish emits none). Devnet zeroes token economics (base cost = 1 wei), so the discounted value floors to 0 — the assertion verifies the discount formula was applied exactly, robust to dust-sized base costs.

Known blocker — deferred to #500

CI is green except one job: Tornado: Solidity coverage (push safety net) — ratchet failure (lines 54.84% < 60%, branches 45.38% < 48%, functions 54.85% < 65%).

This is not introduced by #519. It is inherited from the base branch: #500 (feat/archive-non-v10-contracts) archived ~14 kLOC of V8/V9 Solidity tests, dropping evm-module coverage below the repo ratchet. #519 only adds tests (it cannot raise coverage above what #500 removed). Evidence the wiring itself is sound:

• EVM-Integration matrix: success (3/3)
• 22/24 CI jobs: success
• Independent devnet runtime: 6/6 PASS (create PCA → register agent → publish via PCA → CostCovered on chain → discount per exact tier formula → GET round-trip)

Resolution owner: #500. The coverage ratchet (lower thresholds to the post-archive reality, or add V10 contract tests) belongs in the archive PR's scope, not this feature PR. #519 rebases onto main once #500 lands with coverage resolved. Tracked via a comment on #500.

Post-review round 2 (2026-05-15)

• Naming disambiguation (c7283678): the V10 SDK methods were renamed *ConvictionAccount/*ConvictionAgent → *PublishingConviction* (createPublishingConvictionAccount, topUpPublishingConvictionAccount, registerPublishingConvictionAgent, deregisterPublishingConvictionAgent, isPublishingConvictionAgent, settlePublishingConvictionAccount, getPublishingConvictionAccountInfo, type V10PublishingConvictionAccountInfo). "Conviction account" is ambiguous in this codebase — there are two: publishing (DKGPublishingConvictionNFT, this PR) and staking (DKGStakingConvictionNFT). The V9 names carried the Publishing qualifier for exactly this reason; the bare names were a regression I introduced in the spec. Applied transitively (interface, evm/mock/no-chain impls, facade, daemon routes, api-client, tests, ARCHITECTURE.md); bare Conviction names returned to the v8-v9-archive guard as V9-only.
• Comments capped at ≤2 lines (c7283678): every multi-line V10 PCA comment block trimmed; load-bearing why kept, prose in ARCHITECTURE.md § SDK + daemon PCA write surface is wired to archived V9 contract; V10 PCA NFT has no SDK path #519.

Verification after rename: pnpm -r build green; chain (352✓) / agent (461✓) / cli (1117✓) suites green; devnet HTTP round-trip re-verified 6/6 PASS (HTTP API surface unchanged — rename is internal). Note: the two pre-existing read methods getConvictionAgentAccountId / getConvictionAccountLockDurationEpochs are on the base branch (not introduced here) and left as-is to avoid scope creep — minor pre-existing naming debt.

Post-review round 3 — codex findings addressed (c5762e2d)

Codex finding	Fix
🔴 NFT-undeployed → HTTP 500 (write) / 404 (read) instead of 503	A — typed PcaUnavailableError (code PCA_UNAVAILABLE); evm-adapter throws it on write (requireConvictionNFT) and read (getPublishingConvictionAccountInfo) when the NFT is absent; daemon maps → 503. null now means account-missing only → 404. No more 500/404 on pre-V10 hubs.
🔴 Known PCA reverts → opaque 500	C — InvalidAmount→400, Agent{Already,Not}Registered→409, AccountExpired→409 across all 5 write handlers.
🟡 api-client probe field authorized (V9 wording)	D — renamed authorized→registered (route + client type + tests + a stale cli.ts ref).
🟡 Mock hard-codes discountBps=0 / lifecycle fields	B — MockChainAdapter mirrors the contract's exact getDiscountBps tier ladder; persists createdAtEpoch, derives expiresAtEpoch. Settlement cursor / fullySwept deliberately not modeled in the mock (that is contract accounting — covered by the evm-module hardhat suite + the devnet smoke against the real NFT); documented in-code.

Verification at c5762e2d: pnpm -r build ✓; chain 360✓ / cli 1123✓ suites green; devnet HTTP round-trip re-verified 6/6 PASS (happy path unaffected — A/C/D are error-path/serialization, B is mock-only).

Post-review round 4 — codex round-2 findings addressed (351c2614)

Codex finding	Fix
🔴 classifyPcaRevert incomplete (ZeroAgentAddress / AgentCapReached → 500)	Completed the mapping from the contract's full error set (DKGPublishingConvictionNFT.sol:164-179): ZeroAgentAddress→400, TokenTransferFailed→400, AgentCapReached→409, AccountAlreadyFullySettled→409. Also a fast zero-address reject (400, pre-RPC) in POST + DELETE /api/pca/:id/agent.
🟡 Mock doesn't enforce maxAgentsPerAccount	MockChainAdapter enforces the contract default cap 100 (mirrors :208/:711-712), throws AgentCapReached past the cap so mock-backed tests catch the regression.

Enumerated the contract's full custom-error set to end the incremental review loop (covered 4 reachable errors, not just the 2 flagged). TDD: each behavior driven red→green (6 cli route tests, 3 mock tests). Verification at 351c2614: pnpm -r build ✓; chain 363 / cli 1129 suites green; devnet HTTP round-trip re-verified 6/6 PASS.

Codex review findings addressed in c5762e2d (dedup: 8 comments → 4 issues):

• NFT-undeployed → 500/404 instead of 503 (the pca.ts + evm-adapter.ts comments, both passes): fixed via a typed PcaUnavailableError thrown by the adapter on write+read paths and mapped to 503 by the daemon; null is now reserved for genuine account-missing (→404). Resolves the pre-V10-hub footgun.
• Known PCA reverts → opaque 500: InvalidAmount→400, Agent{Already,Not}Registered→409, AccountExpired→409 across all write handlers.
• api-client authorized: renamed to registered (V10 agent terminology).
• Mock discountBps/lifecycle hard-coded: mock now mirrors the contract's exact getDiscountBps tier ladder + persists creation/expiry metadata. Lazy-settlement cursor / fullySwept are intentionally not re-implemented in the mock — that is on-chain accounting, verified by the evm-module hardhat suite and the devnet smoke against the real DKGPublishingConvictionNFT; faithfully duplicating it in a mock would be reimplementing the contract.

Verified: build + chain (360) / cli (1123) suites green; devnet HTTP /api/pca round-trip re-verified 6/6 PASS. The remaining red CI lane is the Solidity coverage ratchet, which is inherited from #500's V8/V9 test archival (out of scope here — flagged on #500).

[zsculac]

Codex round-2 findings addressed in 351c2614:

• classifyPcaRevert incomplete: rather than only the 2 flagged errors, I enumerated the contract's full custom-error set (DKGPublishingConvictionNFT.sol:164-179) and mapped every route-reachable deterministic one — ZeroAgentAddress→400, TokenTransferFailed→400, AgentCapReached→409, AccountAlreadyFullySettled→409 (was 500). Also added a fast zero-address reject (400, before any RPC) in both POST and DELETE /api/pca/:id/agent, since ethers.isAddress('0x0..0') is true.
• Mock agent cap: MockChainAdapter now enforces the contract default maxAgentsPerAccount = 100 (mirrors :208 / revert at :711-712) and throws an AgentCapReached-shaped error past the cap, so mock-backed tests catch the regression. (Settlement accounting remains intentionally out of the mock — that is on-chain logic verified by the hardhat suite + devnet smoke.)

Built test-first (TDD, red→green per behavior): 6 new daemon-route tests, 3 new mock tests. Verified: pnpm -r build green; chain (363) / cli (1129) suites green; devnet /api/pca round-trip re-verified 6/6 PASS. Remaining red CI lane is still only the #500-inherited Solidity coverage ratchet (out of scope here; flagged on #500).

[zsculac]

Codex round-3 addressed in f2ac30fb:

• NoChainAdapter broke the facade null-contract: the 7 SDK + daemon PCA write surface is wired to archived V9 contract; V10 PCA NFT has no SDK path #519 PCA methods are optional on ChainAdapter, but NoChainAdapter defined them (throwing noChain()), so the facade's typeof guard passed and a direct SDK caller in no-chain mode got an exception instead of the documented null. Fixed by removing those 7 stubs from NoChainAdapter (omission is valid for optional iface members) → facade returns null (SDK contract restored), daemon write routes still 503 via the existing result===null path, and the GET capability probe yields 503 (not 404). getPublishingConvictionAccountOwner is pre-existing, left as-is.
• Mock settlement parity overclaim: taking the reviewer's second option — lastSettledWindow/fullySwept are now explicitly marked STATIC STUBS and settlePublishingConvictionAccount a DELIBERATE NO-OP, with a pinning test locking the intentional scope. Settlement is contract accounting, verified on-chain (hardhat + devnet smoke); deliberately not emulated in a mock.

TDD red→green (facade-null contract test + no-chain GET 503 test + mock stub-pin test). Build green; chain 365 / cli 1130 suites green. Skipped a devnet re-run by design — these changes touch only the no-chain/mock adapters + comments; the devnet path uses the EVM adapter (unchanged, verified at the prior SHA). Only remaining red CI lane is still the #500-inherited coverage ratchet.

Codex review round 4 — addressed in c41c4c7c

1. 🔴 mock expiresAtEpoch = createdAtEpoch + lockDurationEpochs bakes in the wrong invariant
The mock has no wall clock — createdAtEpoch is a synthetic monotonic counter, so every mock account is boundary-aligned by construction. At an epoch boundary the contract (expiresAtEpoch = epochAtTimestamp(expiresAtTimestamp-1)+1) also yields exactly createdAtEpoch+lockDurationEpochs; the +1 divergence the bot describes only occurs for mid-epoch creation, which the mock cannot represent (timestamps are deliberately 0). Modeling the round-up would require inventing a fake mid-epoch offset — pure fiction with no on-chain backing. The arithmetic is correct for the mock's model; the defect was two comments that overclaimed contract parity. Both rewritten to state the boundary-aligned simplification honestly and explicitly disclaim the contract's mid-epoch round-up. Zero logic change; the parity test (line 41) is already correctly named "internally consistent" and is untouched. (Same honest-scoping principle accepted in round 3.)

2. 🟡 write routes return 500 for an unknown accountId
Correct and worth fixing — topUp/register/deregister/settle route through OZ v5 _requireOwned/ownerOf, which reverts ERC721NonexistentToken for an unminted id; that was unclassified and fell through to 500, while GET already returns 404. Added one branch to classifyPcaRevert mapping ERC721NonexistentToken (plus a legacy string-revert fallback) to 404 UnknownAccount — one change fixes all four write routes since they share the helper. +3 route tests pin the consistency.

Verification: pnpm -r build clean; cli suite 1133 passed (+3 new), chain suite 365 passed (unchanged — comment-only), per-package tsc --noEmit clean. CI + EVM Integration re-dispatched on c41c4c7c (heavy matrix is dormant on a feature-branch base, so it runs via workflow_dispatch). Devnet smoke not re-run: this round touches only the cli error-mapping helper and mock comments — the EVM adapter / on-chain path is byte-identical to the SHA already verified 6/6.

[zsculac]

Codex review rounds 5 & 6 — addressed (pushed: 62f9e5eb→158fce9f)

Round 5 #1 🔴 — register read-after-write could turn a mined tx into 500/registered:false (62f9e5eb)
The verification probe (isPublishingConvictionAgent) is now wrapped in its own try/catch, so a probe throw can no longer escape to the handler's outer catch and 500 a registration that already mined (which made callers retry → AgentAlreadyRegistered). Once the tx mines the response is an authoritative 200 + txHash; registered/adapterSupported is tri-state, mirroring the GET route's probedKey shape.

Round 5 #2 🔴 — api-client drops lockEpochs / renames auth methods → breaks SDK consumers — intentional, documented, no code shim
This is a deliberate coordinated break for the 10.0.0-rc major. lockEpochs is now a global protocol param with no contract path; V9 is archived in stacked base #500, so a deprecated alias would only call a removed contract (dead code). No CHANGELOG file exists in the repo. The PR body's "V9 → V10 semantic break" section now explicitly covers the ApiClient TS surface as well, and the broader V9 SDK excision is tracked by #520. Adding non-functional shims was rejected as worse than the documented break.

Round 5 #3 🟡 — GET 404-vs-503 reached into (agent as any).chain (private internal) (62f9e5eb)
Added a public get supportsPublishingConvictionNft() on DKGAgent (mirrors the existing in-facade typeof this.chain.X === 'function' idiom used ~20×). The route now uses it; the single (agent as any) cast is gone, so a future facade refactor can't silently misclassify 503→404.

Round 6 🔴 — PCA EVM writes rethrew raw CALL_EXCEPTION, so custom errors fell through to 500 (5ffb379e)
Correct and impactful: providers surface custom-error reverts as opaque unknown custom error+data=0x…, so err.message carried no name and the daemon's message-based classifier never matched NotAccountOwner/InvalidAmount/ERC721NonexistentToken → HTTP 500 instead of 403/4xx. The owner-happy-path devnet smoke never reverted, and the unit tests fed synthetic message strings, so neither caught it. Fix: a pcaWrite() helper wraps all 5 PCA writes and runs enrichEvmError() on throw before rethrow — mirroring the file's existing isContractMissingRevert/translateRandomSamplingError pattern (DKGPublishingConvictionNFT is already in ERROR_ABI_CONTRACTS, so every PCA + inherited OZ error decodes). This also makes the round-4 ERC721NonexistentToken → 404 mapping actually work on the live chain.

Verification: pnpm -r build clean; chain 368 passed (+3 TDD), cli 1136 passed (+3 TDD), agent 463 passed; per-package tsc --noEmit clean. CI + EVM Integration re-dispatched on 158fce9f (heavy matrix is dormant on a feature-branch base → workflow_dispatch). The only red CI job is the pre-existing Tornado: Solidity coverage (push safety net) ratchet inherited from #500 (it archived ~14k LOC of V8/V9 tests) — no Solidity changed in this PR; deferred to #500 as previously agreed and flagged there.

[github-actions]

🔴 Bug: approve() happens before we validate that the requested amount fits the contract's uint96 parameter. If a caller passes something larger than 2^96-1, the approval tx will still go through and then createAccount/topUp reverts with InvalidAmount, leaving an unintended unlimited allowance behind. Please reject out-of-range values before the allowance branch here and in topUpPublishingConvictionAccount() below.

[github-actions]

🔴 Bug: this reports registered: false whenever the post-write probe is unavailable or transiently fails, even though the tx already mined successfully. That makes the HTTP contract contradict the actual write result and can trigger pointless retries that then hit AgentAlreadyRegistered. The success field should stay true after a successful tx, with probe/verification exposed separately.

[github-actions]

🟡 Issue: the mock only validates each individual top-up amount, not the accumulated topUpBuffer. On chain topUpBalance is uint96, so repeated top-ups past 2^96-1 revert; here they keep succeeding and diverge from EVM behavior. Add a cumulative overflow check before += and cover it with a parity test.
