Activation Contract

Load only when the user explicitly requests Judgment Day or equivalent dual/adversarial review for a concrete target. Judgment Day is a standalone developer tool: judges run whenever asked, on any runtime, and need no review transaction, runtime identity, or delivery-receipt machinery to start. It replaces ordinary 4R as the adversarial method for that target; never run both.

Hard Rules

• Resolve matching project skills before starting and pass the same paths to both judges (jd-judge-a, jd-judge-b) and the fix actor (jd-fix-agent).
• Build one complete immutable target, then launch two blind read-only judges in parallel with identical scope and criteria.
• Each judge returns one neutral findings result and terminates. Wait for both; never accept a partial judgment.
• Never launch review-refuter; two-judge agreement is the corroboration mechanism.
• Only the parent orchestrator merges/persists findings, launches the fix actor (jd-fix-agent), and launches scoped re-judgment.
• Fix only severe findings confirmed by both judges. WARNING/SUGGESTION rows remain info.
• Permit at most two fix rounds and two scoped re-judgments. Re-judgment sees only the frozen ledger plus fix delta and may record fix-caused defects.
• The only terminal verdicts are APPROVED | ESCALATED; never reset or extend an exhausted round budget.
• A judgment issues no receipt and carries no delivery authority: it satisfies no commit, push, PR, or release gate. When the caller explicitly wants delivery authority for the same target, run the ordinary negotiated review lifecycle as its own step; a runtime that cannot uphold receipt guarantees loses the receipt, not the judgment.

Decision Gates

Execution Steps

1. Build the complete immutable target and freeze the scope both judges will inspect.
2. Launch both read-only judges in parallel (jd-judge-a, jd-judge-b) against the same immutable target.
3. Merge findings into the frozen ledger and persist it through the selected artifact store.
4. Ask before round-one correction; run the fix actor (jd-fix-agent) only for confirmed severe IDs.
5. Run both judges again (jd-judge-a, jd-judge-b) only over the frozen ledger plus immutable fix delta.
6. Repeat once at most, then run independent final verification and return the terminal verdict.

Output Contract

Return target identity, round, confirmed/suspect/contradiction/INFO counts, correction work units, scoped re-judgment result, artifact references, skill resolution, and exactly one final JUDGMENT: APPROVED ✅ or JUDGMENT: ESCALATED ⚠️.
