Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/fix-task-finish-force-detect-pipefail.md; R0=7e6c544b3c25c510e3d928bfb4515937a1cd6696.
Impact: task metadata only; the feature workspace starts at 7e6c544b3c.
Refs: .task/fix-task-finish-force-detect-pipefail.md
Why: the reclaim fix needs its authorization boundary, agent receipts and
the independent review verdict in the task card before delivery.
Evidence: SELF receipts /tmp/tasksh-force-implementation-r1-20261020.json
(cursor, success, transport d755fa0) and /tmp/tasksh-force-review-r2-20261020.json
(pi-glm, success, transport a94f06c, verdict PASS); review report at
.task/reviews/2026-10-20-tasksh-force-independent-review.md.
Impact: card metadata only; no behaviour change.
Refs: fix/task-finish-force-detect-pipefail
Why: include the current integration baseline before verification.
Evidence: fetched origin/main=873e957306a791eaa36e5251b45e3ed44a863143.
Impact: integrate upstream changes without rewriting task history.

Why: include the current integration baseline before verification.

Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
Evidence: .task/fix-task-finish-force-detect-pipefail.md -> .task/archive/fix-task-finish-force-detect-pipefail.md; status 已完成（合入前闭合）; PR #657https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/657.
Impact: task metadata only; the card is archived within PR #657 and lands with its merge commit.

Why: include the current integration baseline before verification.
Evidence: fetched origin/main=daf02880bb0aff82c2c127bbc9473b680f429907.

授权与交付终点：修复
scripts/task.sh回收路径的 force 探测缺陷并补回归测试，按现行门禁完成 Review、PR、CI、合入、任务卡闭合与安全回收。不得改动其它门禁语义、不得扩到scripts/svc.sh等同类隐患、不得新增 schema/开关/通用重构；不改子模块 pin、CI 配置与共享规范子模块。交付模式：goal-first（目标、范围和交付终点一次确认；范围内连续推进）
实施执行：agent-per-unit（配置：AGENT-EXECUTION.md）
合入执行：agent（已授权交付范围内，Review 通过、冲突解决且当前 HEAD 的 CI 通过后合入）

结果与验证
cmd_finish的 gitlink 检测改为读取完整清单（git ls-files --stage | awk '$1 == "160000" { found = 1 } END { exit !found }'），与索引大小无关，不再被 SIGPIPE +pipefail吞掉--force；新增回归用例在临时真实仓库中构造 >64KiB 且 gitlink 行在前的索引，断言回收成功。fatal: working trees containing submodules cannot be moved or removed红（证据/tmp/tasksh-force-red-20261020.json、/tmp/tasksh-force-green-20261020.json）；最终 HEAD 上finish子集 21 项全绿（/tmp/tasksh-force-final2-finish-20261020.json）、make test-governance514 项 OK/18 skipped（/tmp/tasksh-force-final2-governance-20261020.json）；PR #657 首轮ci / test因 npm registryECONNRESET失败（基础设施，非代码回归，job 日志/tmp/pr657-job7313.log），同一 SHA 重跑后三项 GATE 全绿。真实组件证据：2026-10-20 Backend 组件工作区git ls-files --stage为 76386 字节、旧式管道 rc=141。scripts/task.sh一行判定与tests/test_task.py一个用例；不改变任何门禁语义（不含 gitlink 时仍不加--force，Git 拒绝后仍禁止rm兜底或追加 force 等级）。非阻塞：scripts/svc.sh等处的... | grep -q早退管道存在同类 pipefail 隐患，本次不修，留待独立任务。合入与清理
