Restore v1 evidence compatibility and isolate bound-event v2 - #44

📝 WalkthroughWalkthroughThe change introduces v2 report-evidence and evidence-pack schemas for audit-event content binding. Producers select v2 for bound events. Consumers select schemas by payload version and preserve readable, unbound v1 metadata. ChangesAudit-event evidence v2
Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to This change restores v1 evidence compatibility while adding v2 for bound audit events, but the current head can still accept mixed-version evidence and does not fully validate bound v2 behavior in regression and installed-package checks; malformed evidence could therefore be accepted or packaging regressions could escape detection, so merge should wait for these fixes.

Inline comments:
In `@docs/compatibility.md`:
- Around line 91-100: Update the v2 compatibility documentation to state that
every v2 report and manifest must contain at least one artifact with role
"agent-policy-audit-event", reflecting the schemas’ contains/minContains
requirement. Clarify that validation fails when no such audit-event entry
exists, and revise row 44’s wording so v2 requires rather than merely can bind
an event.
In `@scripts/check_wheel_contract.py`:
- Around line 1920-1951: Extend the installed consumer smoke dictionary with the
bound v2 report schema and its version constant, validating the packaged JSON
and version values. Keep the consumer invocation after the bound report
overwrites report_output, and assert report_schema_version equals
agent-guard.report_evidence.v2.
In `@src/agent_guard/consumer/_sections.py`:
- Around line 171-175: Update validate_evidence_pack_manifest to enforce a valid
manifest/report version pairing: v1 manifests must use v1 report evidence, and
v2 manifests must use v2 report evidence. Add this validation alongside the
existing schema_version check before the embedded and payload report equality
checks, preserving the current rejection behavior for unsupported versions.
In `@src/agent_guard/evidence_pack.py`:
- Around line 491-507: Update the agent_policy_audit_event_artifacts handling so
an explicitly supplied empty list with a nonempty
agent_policy_audit_event_profile raises ERROR_AUDIT_EVENT_PROFILE, matching the
no-event path behavior. Preserve validation for nonempty prebuilt artifacts and
path-based artifact handling.
In `@src/agent_guard/schemas/agent-guard.report_evidence.v2.schema.json`:
- Around line 318-371: The v2 embedded and standalone manifest schemas duplicate
the artifacts definition without an equality check. Add a contract test that
extracts the artifacts subtree from both schemas and asserts they are identical,
covering the role, content_binding, allOf, and additionalProperties rules.
In `@tests/test_schemas.py`:
- Around line 247-266: Remove the synthetic review_metadata key from
manifest["artifacts"][0] after its invalidity assertion and before appending the
correctly bound artifact. Preserve the existing append/pop pattern so the final
validator.is_valid(value) assertion evaluates the intended valid manifest.
