## 整體 verdict

整體 PASS 率 100%（82/82 layer 項）。

- ✅ 2026-05-21 audit 4 blockers + 5 drifts — 全部修完
- ✅ 2026-05-22 re-audit 4 新 drift — 全部修完
- ✅ Privacy invariant 三層守（sanitizer + dashboard wire + materialize body scan + Layer 8 active_path redaction）— PASS
- ✅ Spec ↔ code 雙向 alignment — 7 dead rejection codes 全部 emit、batch_hash round-trip enforced、failure manifest end-to-end
- ✅ Behavior 守 — 3 eval scenarios SHIP（concurrency / safety_ack / deactivate ack）
- 📋 First-slice accept 項已 codify 進 spec（Layer 0 daemon-spawn / Layer 1 observation.skill / Layer 2 WebSearch query / Layer 7 evidence_summaries default false / Layer 8 hash-verify ordering）

Spec realignment complete。後續若有新 layer 變更，這份 final report 可當基準。

## 給未來 audit 的提醒

1. 用過的 8 個 PR 工作流（A spec / B safety / C behavior / D dashboard / E validator / F daemon）— 風險分組是有效切法；spec docs 先行（PR-A）讓後續 implementation PR 有明確契約。
2. Audit 漏掉的型態 — 2026-05-22 re-audit 找到的 4 個 drift 都是「在 frozen 常數定義但 codebase 從沒 emit」型態。下次 audit 建議加：對 REJECTION_CODES / 任何 frozen union 做「定義 → emit」cross-reference 掃描。
3. Eval scenario 的合理數量 — 不需要每個 PR 都加 scenario；專守「gate 行為」（concurrency / ack / 拒收）的 scenario 比「capability 行為」（能不能引用某 evidence_type）的更有訊號。

## Out of scope（持續延後）

- 3 個低優先 scenario（`evidence-ref-omitted-upstream`、`dedupe-superseded-transition`、`typed-evidence-cite-chain`）— 已有 unit test 守
- Layer 0 daemon-spawn `ARCFORGE_OBSERVE_SELF_ANALYSIS` export — dev plugin disabled 緩解
- Layer 5 `llm_assessment` propagation + `evidence_quality_metadata.basis` 其他欄位 — spec 標 optional
- Transcript-summary evidence（第 5 種 approved source）— 目前無 producer，v2 處理
