7. Governance Stage Extension

This RFC introduces one new governance stage:

stage_id	stage_name	Stage	AIGP Role
27	post_hoc_verification	Post-Hoc Verification	Compare outcome to anticipation, emit verdict, trigger governance action

Stage 27 is traversed after stage 14 (post_invocation_record) and stage 16 (observation_audit). It is the final stage in the governed lifecycle — the point where governance closes the loop between intent and outcome.

7.1 Stage Traversal

graph LR
    S14[Stage 14: RECORD] --> S16[Stage 16: Audit]
    S16 --> S27[Stage 27: VERIFY]
    S27 --> END([end])

In REPORT-TRACE mode, stage 27 produces a TRACE span with:

{
  "stage": 27,
  "stage_name": "post_hoc_verification",
  "anticipation_id": "ant-20260624-001",
  "verification_id": "ver-20260624-001",
  "verdict": "PARTIAL_MATCH",
  "overall_score": 0.78,
  "governance_action": "LOG",
  "duration_ms": 12
}
