fix: address PR #176 review (imran-siddique, carloshvp)

1. integration.yaml: category "Identity and access" -> "Identity & trust"
   (schema enum fix); repository URL now points at the real,
   publicly-reachable computeid-trace-adapter repo instead of a private
   computeid-backend that 404s for readers.

2. convert-to-trace.js: references[] now uses the schema's actual shape
   (rel/id/resolver/digest, schema/trace-claim.json's
   additionalProperties: false rejects name/value). Emits a single
   reference pointing at the evidence bundle by SHA-256 digest (hex,
   per the digest pattern - an earlier attempt used base64url and would
   still have failed schema validation). The record now carries a real
   cnf.jwk and is genuinely Ed25519-signed (adapter-signing-key.pem /
   adapter-signing-pubkey.pem), so TR-ENV-004 and both TR-SIG checks now
   pass for real, not by fabricating a proof-of-possession claim about
   the underlying passport itself - cnf here names the key that signs
   this TRACE record, a separate concern from the AgentPassport's own
   RSA + ML-DSA-65 identity keys, which remain in the referenced bundle.

3. offline-verifier.js: classical_signature_valid and
   ml_dsa_signature_valid were reading the service's own
   signature_valid/pq_signature_valid fields rather than independently
   recomputing them - contradicting the file's own "independent
   verification" claim. Both are now genuinely recomputed from raw
   public_key/signature/signed_payload bytes in the bundle (RSA-SHA256
   via node:crypto, ML-DSA-65 via @noble/post-quantum 0.4.1). Verified
   adversarially: true against a genuine bundle, false against a
   locally tampered payload.

4. CONFORMANCE.md: regenerated against a freshly registered ComputeID
   passport (not the stale fixture, which was correctly failing
   TR-ENV-002 on staleness rather than anything real), with the exact
   command, tool version, and verbatim result recorded. Removed the
   TR-APR-001 citation - no TR-APR module exists in trace-tests 0.5.1.
   Real result: FAIL (7 checks, 1 failure - TR-POL-001 only, an honest
   and permanent scope gap). Added the raw JSON Schema validation
   result against schema/trace-claim.json @ 3a561d84 alongside it: 5
   errors, down from 31, all five being the same disclosed fact
   (model/policy/data_class/build_provenance/runtime.measurement do
   not exist for an identity-only issuer) - none fabricated to force a
   pass.

Added package.json/package-lock.json (previously missing from this
integration's directory - offline-verifier.js and convert-to-trace.js
both require dependencies that were never declared here) and
adapter-signing-pubkey.pem (the record-signing public key named in
cnf.jwk). The corresponding private key is intentionally not
committed (.gitignore'd, matching computeid-trace-adapter's own
pattern) and is held by the maintainer.

+**Result: FAIL at Level 0 — 1 of 7 checks fails.**
 
-This is the real result of running agentrust-trace-tests 0.5.1 against a TRACE record built from an actual, unmodified ComputeID /verify API response (not a hand-built sample). Reproduction steps are in README.md.
+This is the real result of running `agentrust-trace-tests` 0.5.1 against a TRACE record built, moments before this run, from a fresh, real ComputeID `/verify` API response (not a hand-built sample, and not a stale fixture — see "Reproducing this result" below for the exact capture-to-verification timeline).
 
-## The four failures, and why each is expected
+## Exact command and environment
 
-1. **cnf must contain jwk with kty** (2 related findings) — ComputeID passports do not currently bind a proof-of-possession key into the credential. This is a real, genuine gap, tracked in a linked spec issue.
+```
+$ pip install agentrust-trace-tests==0.5.1
+$ node convert-to-trace.js evidence/<fresh-bundle>.json > trace-record.json
+$ trace-tests verify --record trace-record.json --level 0 --max-age 86400
+```
 
-2. **TR-POL-001: policy field is missing or not an object** — expected. ComputeID is an identity-issuance system; it does not evaluate or enforce policy.
+- `trace-tests` version: `0.5.1` (the same version this document's failures are described against — the modules that exist in this release are `TR-ANC`, `TR-ENV`, `TR-POL`, `TR-RTE`, `TR-SCA`, `TR-SIG`, `TR-TXN`; there is no `TR-APR` module in 0.5.1, and an earlier draft of this document incorrectly cited one).
+- `--max-age`: default (`86400` seconds / 24h). Not overridden.
+- Record `iat`: `1789031581` (2026-09-10T09:13:01Z) — the evidence bundle's own `issued_at`, captured seconds before this run.
+- Capture time of this run: 2026-09-10, immediately following passport registration against a live, unmodified ComputeID `/verify` endpoint.
 
-3. **TR-APR-001: appraisal is required** — expected. ComputeID does not produce a third-party appraisal or attestation judgment.

+
+## The one failure, and why it is expected
+
+**TR-POL-001: policy field is missing or not an object** — expected. ComputeID is an identity-issuance system; it does not evaluate or enforce policy, so it has no `policy.bundle_hash` or `policy.enforcement_mode` to report.
+
+## What changed since the previous result in this document
+
+The previous draft of this document reported `FAIL (8 checks, 4 failure(s))`, including a `TR-APR-001` finding that does not exist in `trace-tests` 0.5.1, and a stale `iat` that failed freshness (`TR-ENV-002`) simply because the fixture bundle had aged past `--max-age`. Both were real problems with how the result was produced and recorded, not with ComputeID's evidence itself:
+
+1. **`references[]` now uses the schema's actual shape** (`rel`/`id`/`resolver`/`digest`, per `schema/trace-claim.json`'s `additionalProperties: false`), replacing the previous `name`/`value` fields the schema rejects. `convert-to-trace.js` now emits a single reference pointing at the evidence bundle by SHA-256 digest (hex-encoded, per the schema's `digest` pattern), rather than six fabricated per-check entries.
+2. **The record now carries a genuine `cnf.jwk` and is genuinely signed** (Ed25519, `adapter-signing-key.pem` / `adapter-signing-pubkey.pem`). `cnf` identifies the key that signs *this TRACE record* — a separate concern from the ComputeID AgentPassport's own RSA + ML-DSA-65 identity keys, which remain in the referenced evidence bundle. This is why `TR-ENV-004` and both `TR-SIG` checks now pass: the record is honestly, verifiably signed, by a key named in the record itself.
+3. **`offline-verifier.js` now independently recomputes both signature checks.** It previously read `bundle.signature_valid` / `bundle.pq_signature_valid` — the service's own self-reported flags — which contradicted its documented claim of independent verification. It now recomputes RSA-SHA256 (PKCS#1 v1.5) against the embedded `public_key`, and ML-DSA-65 (via `@noble/post-quantum` 0.4.1) against the embedded `pq_public_key`, both over the embedded `signed_payload`. Verified adversarially: both correctly return `true` against the genuine bundle and `false` against a locally tampered payload.
+4. **`iat` is now genuinely fresh** because the evidence bundle itself is freshly captured (see "Reproducing this result"), not because freshness was special-cased or the record's clock was patched.
+
+`appraisal` and `data_class` remain a residual, structural gap common to every top-level-schema validation attempt below — see next section.
+
+## Full JSON Schema validation (`schema/trace-claim.json` @ `3a561d84d752794b9afa994ce16ed35c24ac0acb`)
+
+`trace-tests verify` checks the module-based rules above; it is not a full JSON Schema validator. Running the record through the pinned schema directly (Python `jsonschema`, `Draft202012Validator`) gives a stricter, complementary result:
+
+```
+5 schema errors
+- [] : 'model' is a required property
+- [] : 'policy' is a required property
+- [] : 'data_class' is a required property
+- [] : 'build_provenance' is a required property
+- ['runtime'] : 'measurement' is a required property
+```
+
+Down from 31 errors in the previous submission (which included the `references[]` shape defects fixed above). All five remaining errors are the same, single, honestly-disclosed fact: **ComputeID issues identity credentials; it does not run model inference, evaluate policy, execute tool calls, track build provenance, or hold a hardware measurement.** `runtime.measurement` is unconditionally required by the schema whenever `runtime` is present — including for `runtime.platform: "software-only"` — even though no measurement can exist for a software-only origin; TRACE-MAPPING.md §3 already documents this as "not populated," not an oversight. None of these five fields is fabricated here, and none of the five errors is expected to be fixable without ComputeID beginning to perform work (policy enforcement, model inference, hardware attestation) it does not do today.
 
 ## What this result proves
 
-That this adapter's mapping is honest and internally consistent: every failure traces directly to a documented scope boundary (identity issuance, not execution attestation), not to an implementation defect. The two hardest cryptographic checks — classical and post-quantum signature verification — pass, both independently, both adversarially tested (verified true against the genuine ComputeID CA certificate, verified false against a locally-generated fake certificate with a different key).
+That this adapter's mapping is honest and internally consistent: the one remaining `trace-tests` failure and all five schema errors trace directly to a documented scope boundary (identity issuance, not execution attestation), not to an implementation defect. Every fixable defect identified in review — the `references[]` shape, the unsigned record, the non-independent signature checks in `offline-verifier.js`, the wrong digest encoding, the stale freshness reading, and the nonexistent `TR-APR-001` citation — has been fixed and is demonstrated above, not asserted.
+
+## Reproducing this result
+
+Because `iat` freshness (`TR-ENV-002`) is time-bound, this exact `trace-tests` pass/fail count will not reproduce indefinitely from a static fixture — that is expected, correct behavior (an old record should eventually read as stale), not a flaw. To reproduce a fresh result:
 
-## Fixed during this test
+1. Register a new ComputeID AgentPassport and fetch its `/verify` response (this is the evidence bundle format `convert-to-trace.js` expects).
+2. Run `node convert-to-trace.js <fresh-bundle>.json > trace-record.json` immediately after.
+3. Run `trace-tests verify --record trace-record.json --level 0` immediately after that.
 
-An earlier draft of convert-to-trace.js used a placeholder eat_profile value. Corrected to the TRACE-required tag:agentrust-io.com,2026:trace-v0.2 before this result was produced.
+The `TR-POL-001` failure and the 5 schema errors above are not time-bound and will reproduce from any ComputeID evidence bundle, fresh or not.

 **What this does NOT claim**: this integration does not pass TRACE conformance at Level 0, Level 1, or Level 2 today. See CONFORMANCE.md for the exact, current, machine-readable result and why each failure is expected given ComputeID's scope. No trace_conformance_level is declared in integration.yaml for this reason.
 
-ComputeID is an identity-issuance system, not an execution-attestation runtime: it does not evaluate policy, run model inference, or execute tool calls, so it does not populate TRACE's policy or appraisal fields. It also does not currently bind a proof-of-possession key (cnf/JWK) into the credential.
+ComputeID is an identity-issuance system, not an execution-attestation runtime: it does not evaluate policy, run model inference, or execute tool calls, so it does not populate TRACE's `policy`, `model`, `data_class`, or `build_provenance` fields.

+The TRACE record itself is genuinely signed — `cnf.jwk` names a real Ed25519 key (`adapter-signing-key.pem` / `adapter-signing-pubkey.pem`), and `signature` is a real Ed25519 signature over the record's canonical JSON, verified by `trace-tests` itself (see CONFORMANCE.md). This is a separate concern from the ComputeID AgentPassport's own RSA + ML-DSA-65 identity keys, which sign the identity evidence this record *references*, not the record itself.

 ## What is verified
 
-A reviewer can reproduce, from this repository alone, with no live dependency on ComputeID's service: that evidence/opaque-diligence-demo-fresh.json is a genuine, unmodified ComputeID /verify response, independently checkable via offline-verifier.js and the included ca-cert.pem with zero network calls; that converting this real evidence into a TRACE record produces the exact result in CONFORMANCE.md; and that the hash-chained ComputeID audit log is independently verifiable via verify-audit-chain.js (requires live database access — documented as the one check that cannot be reproduced from a static bundle alone).
-
-## cnf / proof-of-possession gap
-
-TRACE requires cnf with a JWK kty for proof-of-possession binding. ComputeID passports do not currently carry this. Tracked as a separate spec question, since it touches how TRACE could represent our existing DPoP-based proof-of-possession model.
