feat: adopt agentrust-trace; produce GatewayClaim envelope - #113
Merged
Conversation
Replace cmcp's local TRACE schema with the canonical agentrust-trace package. GatewayClaim wraps canonical GatewayTrace fields (eat_profile, iat, subject, runtime, policy, cnf) inside a cmcp-specific envelope that adds gateway addenda (session_id, audit_chain, call_summary, catalog, attestation freshness). - pyproject.toml: add agentrust-trace>=0.1 dep; drop jsonschema (pulled transitively by agentrust-trace) - trace_claim.py: full rewrite — TraceClaim dataclass → GatewayClaim Pydantic model; provider → canonical platform mapping; enforcement mode "enforcing" → "enforce"; hex public key → OKP JWK in trace.cnf - verify.py: update all field paths to new envelope structure; validate with GatewayClaim.model_validate instead of JSON Schema file; StrEnum - schemas/trace-claim.schema.json: updated to GatewayClaim envelope - tests: updated for new API and field paths; 29 tests, all passing Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
