[AVAILABLE], precisely scoped. packages/runtime/src/services/verification-service.ts. CLAIMS.md 2.15.
An earlier six-stage verification pipeline (@parmana/verification) existed and was deleted (“retired in Session 5, it had no real implementation and no real test coverage,” per CLAIMS.md §4). It is not documented here as existing. If you see references to Authority/Intent/Evidence verification stages elsewhere, they describe that retired package or a not-yet-built future addition, not current behavior.

​
The 3 checks, exactly

// packages/runtime/src/services/verification-service.ts:90-153
  1. Integrity, recompute the Trust Record’s canonical hash; must match the stored trustRecordHash.
  2. Signature, the stored cryptographic signature must verify against the stored public key.
  3. Authorization binding, every APPROVED execution must carry a non-empty authorizationId in its metadata. REJECTED-decision executions are exempt.
All three checks always run, independently, regardless of whether an earlier one failed, so a single verification report can name every check that failed, not just the first (runChecks() accumulates failures into an array rather than short-circuiting).

​
Two different operations, two different routes

SDK callHTTPWhat it does
client.verification.verify(id)POST /verifyRuns a fresh verification; appends a new Verification to the record’s history
client.verification.get_latest(id)GET /verification/:idReads back the most recent Verification without re-verifying
These are genuinely different routes (packages/api/src/routes/verify.ts vs. verify-get.ts), not the same endpoint called twice, a distinction the Python SDK only got right this session (see Python SDK).

client.verification.get_latest() -- cached (GET /verification/:id):

Tampering is actually caught

packages/api/test/verification-negative.integration.test.ts, “reports FAILED when the persisted record is tampered after execution”, proves this end to end, not just at the unit level.
