+2. `SP_REPORT`
+3. `TOK021_REPORT`

+### `scripts/ci/tok007_release_recheck.sh`
+

+2. `SP_REPORT`
+3. `TOK_RUNTIME_READINESS_REPORT`
+
+### `scripts/ci/final_decision_consistency_check.sh`
+
+1. `TOK007_FILE`
+2. `SP_FILE`
+
+结论：
+
+1. 当前四个脚本都通过“扫历史目录里最新文件”的方式串联证据。
+2. 这种方式无法证明输入属于同一次发布运行，必须被 `run_id + manifest` 方案替换。
+
+## P2-A-02 `run_id` 生成规则
+
+格式：
+
+`YYYYMMDD_HHMMSS_<short_sha>_<env>[-rNN]`
+
+规则：
+
+1. `YYYYMMDD_HHMMSS` 使用执行开始时间。
+2. `<short_sha>` 使用 8 位提交号。
+3. `<env>` 使用本次发布环境标识，如 `staging`、`prod`、`localmock`。
+4. 若同秒内重复生成，追加 `-rNN` 顺序号，避免目录冲突。
+
+## P2-A-03 发布目录结构
+
+```text
+reports/releases/<run_id>/
+  manifest.json
+  logs/
+  gate_verification/
+  review_outputs/
+  evidence/
+```
+
+约束：
+
+1. 同一次运行的产物只能写入自己的 `<run_id>` 目录。
+2. 历史目录只读，不允许被当前运行覆盖。
+
+## P2-A-04 `manifest.json` 必填字段
+
+最小字段：
+
+- `run_id`
+- `commit_sha`
+- `env`
+- `created_at`
+- `source_env_file`
+- `artifact_paths`
+- `decision_inputs`
+
+`artifact_paths` 最少应覆盖：
+
+- `staging_release_pipeline_report`
+- `superpowers_release_pipeline_report`
+- `staging_evidence_autofill_report`
+- `tok007_recheck_report`
+- `final_decision_consistency_report`
+
+`decision_inputs` 最少应覆盖：
+
+- `staging_run_log`
+- `superpowers_stage_validation_report`
+- `token_runtime_readiness_report`
+- `tok006_gate_bundle_report`
+- `supply_gate_review_report`
+- `final_decision_report`
+
+## P2-A-05 `staging_release_pipeline.sh` 输入改造草稿
+
+方案：
+
+1. 该脚本成为 manifest 的创建者。
+2. 启动时生成 `run_id` 和 `reports/releases/<run_id>/manifest.json`。
+3. 下游脚本统一接收 `--manifest <path>`。
+4. 不再从历史目录回扫 `LATEST_*` 文件，而是把本次步骤产物写回 manifest。
+
+## P2-A-06 `staging_evidence_autofill.sh` 输入改造草稿
+
+方案：
+
+1. 增加 `--manifest` 作为首选输入。
+2. 只读取 manifest 中的 `decision_inputs` 和 `artifact_paths`。
+3. 当 manifest 缺少必填路径时直接失败，不再回退到“最新文件”。
+
+## P2-A-07 `tok007_release_recheck.sh` 输入改造草稿
+
+方案：
+
+1. 增加 `--manifest` 输入。
+2. 复审所需的 TOK006 / stage validation / token readiness / SUP review / final decision 路径全部从 manifest 读取。
+3. 复检脚本只审当前 `run_id` 的证据，不扫描历史目录。
+
+## P2-A-08 `final_decision_consistency_check.sh` 输入改造草稿
+
+方案：
+
+1. 增加 `--manifest` 输入。
+2. final decision、tok007 recheck、stage validation 三个来源全部绑定到同一个 `run_id`。
+3. 若 manifest 中任一路径缺失或跨 run_id，直接判定 `FAIL`。
