 ## 当前批次总结
 
 - 批次：`abg-p9-1-continuous-development-01`。
 - 已完成：三份专家规格已推送；PMO 当前冻结 authority 为 `p9.1-contract-r2`（权威 22-test baseline）。
 - 视觉切片：candidate `0c640eb` 已作为 `71b7f71` 集成；六帧 844x390，付费使用 0/4、USD 0/5，Owner visual gate 仍开放。
-- 当前 Gate：H1 candidate `f9b1b22`; R5 scope/preflight passed but wrong mkdir path stopped before archive/import; fresh R6 uses fixed helper SHA `9581d767`, downstream frozen。
-- PMO 监控循环：`RUNNING`，目标 HAPI `00454238-2e5b-4b36-b5f2-cf4bcbc17c43`，间隔 600 秒；wait=真实 timer/observe cell，observe=`inspect_peer` + ledger。
+- 当前 Gate：H1 candidate `f9b1b22`; R6 helper/import/atomicity/22 scripts all passed, but baseline capture root guard stopped before second archive; fresh R7 uses helper SHA `f8fd9431`, downstream frozen。
+- PMO 监控循环：`EXITED`，原因：R6 legal INVALID terminal observed；R7 激活后重新登记 600 秒循环。
 - 结束 Gate：独立 reviewer PASS 后发布新 H5，Owner 再判断理解、乐趣和继续意愿。

+matrix (`success=32 rejected=28 exact_guild_ids=2 legacy_leaks=0`) and all 22
+authority rows (12 headless, 10 normal at fixed FPS 60). The baseline capture

+# Goal: Independently review Foundation atomicity with dual-root capture helper
+
+> Stage: foundation-atomicity-independent-rereview-r7
+> Started: 2026-08-13T10:52:00+00:00
+> Task ID: `ABG-P9.1-FOUNDATION-ATOMICITY-REVIEW-R7`
+> Baseline: `b422d4cee444beed8bf405747aeb3025c2cf2cd9; branch=review/abg-p91-foundation-atomicity-r7; clean`
+> Frozen spec: `.agent-taskgraph/spec.md revision p9.1-spec-r2; docs/runtime/PHASE9_1_ARBITRARY_PARTY_FIRST_SESSION_CONTRACT.md revision p9.1-contract-r2`
+> Graph node: `.agent-taskgraph/graph.yaml#p91_foundation_atomicity_h1`
+> Independent contract: 不适用
+> Context manifest: `context.md`
+> Context revision: `p91-foundation-atomicity-review-r7`
+> Legal terminal: **ABG-P9.1-FOUNDATION-ATOMICITY-REVIEW-R7 PASS**，或 **ABG-P9.1-FOUNDATION-ATOMICITY-REVIEW-R7 FAIL: <最早产品失败边界>**，或 **ABG-P9.1-FOUNDATION-ATOMICITY-REVIEW-R7 INVALID: <最早 harness/环境/证据边界>**
+
+## Objective
+
+Review immutable f9b1b22 from zero. Verify tools, Bash3 no-Godot preflight, helper SHA f8fd94316ecbd4c40797975d76b52bc3ec85dcfe77c3a693c357bfff0a74b346, and manifest-derived scope. Invoke only the fixed helper for both candidate and rejected baseline archives, using root names exactly under /private/tmp/abg-p91-foundation-atomicity-r7-candidate.* and /private/tmp/abg-p91-foundation-atomicity-r7-baseline.*. Fresh import, atomicity, exact IDs, 22 rows parsed directly (12 headless/10 normal, normal fixed-fps 60), and four-group 30-frame byte-identical capture comparison must all pass. Report PASS, product FAIL or harness INVALID at earliest boundary; never repair.
+
+## 图输入、输出与写入范围
+
+- 直接依赖（needs）：p91_foundation_atomicity_h1 candidate f9b1b22
+- 必须读取（consumes）：f9b1b22 fixed source, fixed helper SHA f8fd9431, H1 task-manifest writes authority, R6 INVALID 283ced64, hash-fixed accepted summary 3de791bb
+- 必须产出（produces）：fresh read-only PASS, FAIL or INVALID terminal with reviewer-owned sanitized evidence
+- 唯一写入范围（writes）：none in repository; reviewer-owned isolated temporary evidence only
+- 路由：PASS -> p91_domain_implementation；FAIL -> failed；最大尝试 1
+
+## 分配记录
+
+- Role ref：`role:p91-foundation-atomicity-reviewer-r7`
+- 角色职责：Independently verify immutable f9b1b22 with dual-root fixed helper and fresh capture evidence
+- 角色生命周期：task-scoped
+- 派给：p91-foundation-atomicity-reviewer-r7
+- 分配理由：职责匹配
+- 连续性：fresh dual-root capture recovery after R6 INVALID; no prior reviewer execution evidence reuse
+- 工作区：`/Users/wusumac/Documents/game/tmp/aetherbound-guild-worktrees/p91-foundation-atomicity-review-r7`（分支：`review/abg-p91-foundation-atomicity-r7`）
+- Runtime requested：`runtime=hapi; flavor=codex; model=gpt-5.6-sol; effort=xhigh; permission=yolo; visibility=visible`
+- Runtime observed：`PENDING`
+- Runtime verification：`PENDING`
+- Session evidence：`PENDING`
+- Dispatch bootstrap：`dispatch.md`
+- Dispatch message：`NOT_SENT`
+- Identity ACK：`PENDING`
+- 完整启动方式：派发预览批准后由所选 runtime 控制面生成
+
+## 报告协议
+
+- 完成、失败或阻塞时通知 PMO，并引用任务号、legal terminal 和证据路径。
+- worker 不修改 PMO 管理的 queue ledger、STATUS 或角色注册表。
+
+## 验收标准（证据门）
+
+- [ ] Verify helper SHA exactly; fixed tools and Bash3 no-Godot preflight pass
+- [ ] Parse H1 manifest writes and compare mechanically to Git; prove candidate/parent/rejected ancestry
+- [ ] Use only fixed helper with exact candidate/baseline root prefixes for both archives
+- [ ] Atomicity matrix, exact IDs and zero legacy leaks pass
+- [ ] Parse accepted summary rows directly; exactly 12 headless/10 normal; normal fixed FPS 60; all 22 pass strict diagnostics
+- [ ] Fresh four-group 30-frame candidate/baseline capture inventories and PNG bytes identical; sanitize/hash/cleanup
+
+## Frozen（禁止触碰，明确列出）
+
+- Do not edit/repair/stage/commit/push/merge repository files or refs
+- Do not reuse prior reviewer execution evidence
+- Do not recreate helper commands or use other root prefixes
+- Do not hand-author paths or mode map; use JSON/summary parsing
+- Do not use rm/unlink/zsh/mapfile/variables status/path or expose credentials/foreign argv
+- Do not implement downstream/package/sign/upload/release; harness failures are INVALID
+
+## Estimate
+
+helper/source preflight 15m; atomicity 30-60m; 22 scripts 30-60m; captures 45-90m; confidence high
+
+## 完成时交付
+
+- graph 节点约定的 produces
+- 验收证据与残余风险
+
+## Review Classification
+
+- `PASS` only when every declared gate passes on the immutable candidate.
+- `FAIL` only for a candidate product defect at the earliest declared product boundary.
+- `INVALID` for tool, shell, import, test harness, capture, cleanup, concurrent-load,
+  environment or evidence-integrity failure that prevents a product judgment.
+- Stop at the first terminal boundary. Do not retry, repair, continue later gates or
+  convert an `INVALID` into a product `FAIL`.

+# Staffing Change: Foundation Atomicity Reviewer R7 Dual-Root Capture Recovery
+
+> Team revision: `rev-p9.1-1 -> rev-p9.1-1`
+> Status: `APPLIED`
+> Type: `REPLACE`
+> Proposed by: `PMO / 2026-08-13T11:01:00Z`
+> Approved by: `PROJECT.md environment recovery policy and Owner instruction to continue`
+
+R6 passed all pre-capture gates but the fixed helper rejected the reviewer
+baseline root prefix before the second archive. R7 uses fresh helper
+`.agent-taskgraph/reviewer-tools/foundation_atomicity_archive_r7.sh`, SHA
+`f8fd94316ecbd4c40797975d76b52bc3ec85dcfe77c3a693c357bfff0a74b346`, which
+accepts exactly `abg-p91-foundation-atomicity-r7-candidate.*` and
+`abg-p91-foundation-atomicity-r7-baseline.*`. All earlier gates run fresh.
+
+Final result: `APPLIED / pre-dispatch`.
