# Reopen a prior decision when evidence changes.

Record counterevidence, expiry, refuted assumptions, and manual review without overwriting the prior decision.

**CONTRACT REVIEW · TEST_ONLY:** Review-candidate contract and local fixture evidence only · no distributed SDK, operational API, publisher parity, or decision authority

## v1 distinguishes four review triggers

- COUNTEREVIDENCE — new material conflicts with the current path
- REFERENCE_STALE — an external reference expired
- ASSUMPTION_REFUTED — a material assumption was contradicted
- MANUAL — the accountable human explicitly requests review

## DECIDED and CLOSED can return to REVIEW_REQUIRED

Do not delete a prior decision or assume it remains current. Bind the ReviewTrigger to its source node and time, then transition the case to REVIEW_REQUIRED.

1. **Verify the new reference** — Check schema, tenant, scope, lifetime, and publisher binding.
2. **Find affected nodes** — Connect the assumption, option, Scenario, or Decision that is now in question.
3. **Open a new version** — Preserve the prior snapshot while updating version and lineage.
4. **Require human review** — Revisit open questions, dissent, and conditions without automatic reselection.

## Review completion is not RAIFFA eligibility

A reorganized PÓLYA case does not grant approval or permission to act. RAIFFA requires a separate EligibilityGateRef bound to the current DecisionCaseRef, actor, and scope.

> **Current integration state:** PÓLYA-to-RAIFFA publisher parity and an operational receiver remain under contract review. Never interpret READY_FOR_RAIFFA as approval.
