Not recommended as canonical CLAS SDK until proof envelope, algorithm casing, and verification pipeline are runtime-core sourced. - ---- - -## Required audit checklist findings - -### A. Current receipt signing logic -- `CommandLayer.wrap()` builds receipt input + execution metadata, then calls `createReceipt`. -- `createReceipt` canonicalizes payload and signs canonical string bytes with Ed25519 private key from PEM. -- Output includes top-level `proof` legacy fields. - -### B. Current verification logic -- Only remote verifier call via `fetch(verifierUrl, { body: { receipt } })`. -- No local signature verification API in SDK surface. - -### C. Local canonicalization/hash/signature code -- Canonicalization: custom sorted-key canonicalizer. -- Signature: WebCrypto `subtle.sign("Ed25519", ...)` and base64 encoding. -- No explicit receipt hash value materialized in proof envelope. - -### D. Local schema/proof definitions -- Receipt schema requires `proof.canonical`, `proof.alg`, `proof.signature`, `proof.kid`, `proof.signer_id`. -- `proof.alg` enum only allows `ed25519`. - -### E. Legacy fields status -- `hash_sha256`: not present. -- `signature_b64`: not present. -- `proof.alg`: present (legacy). -- `proof.canonical`: present (legacy). -- `proof.canonical_id`: not present. -- top-level `signature.*`: not present. - -### F. Algorithm casing -- Crypto API uses WebCrypto algorithm name `Ed25519` internally. -- Receipt payload/schema/tests use lowercase `ed25519` (mismatch with canonical requirement). - -### G. Key config names -- Public constructor supports `privateKeyPem` and deprecated alias `privateKey`. -- No `privateKeyPemOrDer` in current API. -- Internal normalization: `privateKeyPem = config.privateKeyPem ?? config.privateKey`. - -### H. Current public SDK API -- `new CommandLayer({ signer|agent, kid, privateKeyPem|privateKey, verifierUrl, timeoutMs, canonicalization })` -- `wrap(verb, handler)` => `{ output, receipt }` -- `verify(receipt)` => remote verifier response -- local schema helpers exported from `trust.ts` - -### I. Example output shape -Examples/docs show: -- top-level `proof` object with `canonical`, `alg`, `signature`, `kid`, `signer_id`. - -### J. README claims -- Markets SDK as signed-receipt + verifier integration. -- States local validation is schema-only and remote verify is source of truth. -- Does not yet document canonical runtime-core proof envelope. - -### K. Test coverage -- Strong coverage for legacy receipt construction/schema validity and remote verify request wiring. -- No tests for runtime-core API usage or canonical metadata.proof envelope. - -### L. npm publish readiness -- `package.json` has publish metadata, but canonical alignment blockers above remain. -- Build/test not currently passing in this environment due to install/build failures. +**9/10** after final release packaging/version cleanup: +- add explicit package `exports` map, +- finalize semver decision, +- re-run `npm pack` after build and verify packaged contents (including schemas). + +## 3) Commands and validation status +### Codex environment (this container) +- Registry/network constraints may prevent reproducible npm install in this environment. +- These environment-specific issues should not be treated as product/runtime failures. + +### Verified local Windows validation (authoritative for this PR update) +- `npm install` ✅ passed +- `npm run build` ✅ passed +- `npm test` ✅ passed +- Result: **17 passed, 0 failed** + +## 4) Does agent-sdk currently emit receipts VerifyAgent can verify? +**Yes, based on local validated test suite and canonical proof-shape alignment.** + +- Canonical proof shape now follows `receipt.metadata.proof.*`. +- Local tests indicate emitted receipts are runtime-core-verifiable. + +## 5) Does agent-sdk currently verify runtime receipts? +**Evidence indicates yes at the SDK behavior level under local validated tests.** + +- Local test pass (17/0) supports runtime interoperability expectations for canonical receipts. +- Remaining release risks are packaging/version signaling, not receipt verification semantics. + +## 6) Remaining release blockers (real blockers only) +1. Package version remains `1.1.0` (release bump decision pending). +2. No explicit `exports` map in `package.json`. +3. `npm pack` should be re-run locally after build as final packaging gate. +4. Confirm schema files are included in built output (`dist/src`) and npm tarball. +5. Decide semver path: `1.2.0` vs `2.0.0`. + +## 7) Version recommendation +- **Likely `1.2.0`** if no external users rely on the old proof shape. +- **Use `2.0.0`** if `metadata.proof` migration is treated as a public breaking API change for downstream consumers. + +## 8) Release recommendation +**Not ready to publish yet, but close.** + +- Remaining work is packaging/version/export cleanup. +- No additional runtime-core protocol/signature architecture changes are the primary blocker at this stage. + +## 9) Final readiness summary +- Runtime/protocol alignment: **substantially complete**. +- Local quality gate: **passed** (`install`, `build`, `test`; 17/0). +- Release gate: **pending packaging + semver finalization**.
