Pull request overview
This PR adds a quarterly “absence fail-closed” drill script to concretely regression-test the dead-man trip behavior (Issue #180 / ADR-0069 / Card #223), with accompanying self-tests and CI syntax registration.
Changes:
- Add
governance/drill/failclose-test.shto self-test the stale-heartbeat predicate, probe live heartbeat freshness (read-only), and (optionally) perform a real set+readback+immediate reset ofAUTO_MERGE_DISABLED. - Add new drill tests:
test-failclose.sh(dry-run assertions) andtest-history.sh(append-only history + red-rate aggregation assertions). - Register the new scripts for
bash -nsyntax checking ingate.yml.

2. Flaky threshold boundary test 🐞 Bug ☼ Reliability
predicate_selftest() computes the boundary case using one "now" timestamp but trip_if_stale() recomputes "now" internally, so a 1-second tick can turn an equality case into "age > threshold" and intermittently fail the drill. This makes quarterly evidence runs non-deterministic and can produce false failures.
Agent Prompt
### Issue description
`predicate_selftest()`’s boundary assertion (“exactly at threshold → no-trip”) is nondeterministic because `trip_if_stale()` samples the current epoch internally with `date -u +%s`, while the test computes `last_success_epoch` using a different `date -u +%s` call. If the second call happens one second later, the computed age becomes `threshold+1`, flipping the result to `trip`.
### Issue Context
This script is intended as periodic drill evidence (fail-closed regression). A flaky boundary assertion undermines trust in drill results.
### Fix Focus Areas
- governance/drill/failclose-test.sh[47-50]
- governance/drill/failclose-test.sh[61-64]
### Implementation notes
- Sample `now_epoch=$(date -u +%s)` once in `predicate_selftest()` and pass it into `trip_if_stale()` (add a `now_epoch` parameter), or
- Refactor `trip_if_stale()` to accept `age_seconds` directly for tests, or
- Add a small epsilon in the boundary test (`threshold*3600 - 1`) if you only want to assert “not stale at/before threshold” without requiring exact equality.

3. Decimal threshold breaks arithmetic 🐞 Bug ≡ Correctness
threshold_from_butler() accepts decimal hours (regex allows floats), but trip_if_stale() uses Bash integer arithmetic with $2 * 3600, which errors or misbehaves for values like 0.5. This can cause incorrect trip/no-trip results when FAILCLOSE_STALE_HOURS is set to a decimal.
Agent Prompt
### Issue description
The script validates `THRESH_H` with a regex that allows decimals (e.g. `0.5`), but later uses Bash arithmetic expansion `(( ... $2 * 3600 ))`, which only supports integers. This creates a configuration footgun: inputs that pass validation can still break the predicate.
### Issue Context
`FAILCLOSE_STALE_HOURS` is explicitly documented as an overridable input; the script should either fully support decimals or explicitly reject them.
### Fix Focus Areas
- governance/drill/failclose-test.sh[47-50]
- governance/drill/failclose-test.sh[70-78]
### Implementation notes
Option A (simplest): restrict to integers only:
- Change the validation regex to `^[0-9]+$`.
Option B: support decimals:
- Compute threshold seconds via python (already required) and pass an integer seconds threshold into Bash, or use `awk`/`python` to compare floats safely.

4. Trap reset can fail silently 🐞 Bug ☼ Reliability
reset_trap() only logs/marks infra when the fallback reset succeeds, but does not emit an error, manual recovery command, or force a non-zero outcome if the reset attempt fails. If the script crashes after setting AUTO_MERGE_DISABLED=true and the reset fails (network/permissions), the org-level automerge breaker may remain enabled without a clear loud signal.
Agent Prompt
### Issue description
The EXIT trap is the last safety net to avoid leaving `AUTO_MERGE_DISABLED=true`. Currently, `reset_trap()`:
- attempts `var_set false`,
- only calls `infra ...` when that attempt *succeeds*,
- produces no `::error::` and no manual remediation instructions when the reset attempt fails.
This violates the script’s stated invariant (“真置位不可留”) in the failure mode where the trap is most needed.
### Issue Context
`AUTO_MERGE_DISABLED` is an org-wide breaker used to stop task dispatch and automerge; leaving it set blocks normal operations.
### Fix Focus Areas
- governance/drill/failclose-test.sh[96-107]
- AGENTS.md[20-24]
### Implementation notes
- In `reset_trap()`, capture and check the return code of `var_set false`.
- If reset fails, print `::error::` plus an explicit manual reset command and (optionally) a `gh api ...` readback command.
- Consider retrying reset a few times with small backoff.
- Ensure failure is visible: either force exit 2 from the trap (while preserving the original exit code where appropriate) or print a clearly machine-greppable fatal line so the operator can’t miss it.

[严重级别：中] 边界用例存在跨秒竞态，会偶发变红。
L62 在调用方取一次 date，trip_if_stale 内部再取一次。若两次取值跨越秒边界，age 变为“阈值秒 + 1”，判定为 trip，边界断言失败并报“边界语义漂移”。建议让 trip_if_stale 接受可选的 now 时戳，边界用例复用同一时戳。

[严重级别：高] RESET_AT 过早赋值使 trap 兜底复位失效。
L125 在读回校验（L127）之前设置 RESET_AT。若 var_set false 静默失败（var_set 把 PATCH/POST 的错误全部丢弃），读回不为 false 时函数 return 1，reset_trap 因 RESET_AT 非空而跳过复位。结果：org 变量 AUTO_MERGE_DISABLED 停留在 true，线上自动合并被打断，与 L12、L102 的声明相反。
修复方向：只在读回校验通过后记录 RESET_AT；并让 var_set 返回真实失败状态。

test-history.sh 中调用 record 的负向用例：在每次拒绝操作前后保存并比较历史文件
H，确保命令确实因预期校验失败且未写入任何内容，而不是被无关的 Python、路径或解析错误误报；补充既有 JSONL 行损坏后 record
拒绝追加的场景，并同样验证 H 保持不变。

区分 NO-SURFACE 与缺少 surface 字段。
NO-SURFACE 不计入 red_rate 分母。行 42 的记录虽缺少 surface 字段，但 verdict 为 green，因此应计入分母，0.75 正确。若要覆盖 NO-SURFACE 契约，请使用 "verdict":"NO-SURFACE" 并期望 1.0；否则删除注释中的 no-surface。

test-history.sh 中该测试记录或断言注释，明确缺少 surface 字段但 verdict 为 green 的记录应计入 red_rate
分母；若测试 NO-SURFACE 契约，则将 verdict 改为 NO-SURFACE 并断言 1.0，否则移除 “no-surface 不入分母” 说明。

动机
宪法 §6 缺席 fail-closed：审计包/心跳缺席→自动合并自动关闭，不能只在设计文档里成立，必须周期性实测（#180 先例，ADR-0069 决策 6 要求每季至少一次实测回归）。
变更清单
governance/drill/failclose-test.sh：deadman_stale_hours+ 当前真实心跳新鲜度探针FAILCLOSE_DRY_RUN=0）：PATCH org 变量AUTO_MERGE_DISABLED=true→ GET 读回断言 → 立即复位 → GET 读回断言 false，置位/复位时戳输出；trap 兜底复位（真置位不可留）FAILCLOSE_DRY_RUN=1（默认）：凭据不足时以"将要置位"判定输出为证据，不动真变量test-failclose.sh（dry-run 6 断言，永不动真变量）+test-history.sh（台账 append-only/红率聚合 10 断言）；gate.yml bash -n 登记首演实录（AC-3 证据，2026-08-21 UTC，org admin 凭据充足走真置位）
复位后独立复核 org 变量值 =
false；置位窗口约 3 秒，线上自动合并不受影响。台账failclose-drill记录：mode=real, outcome=pass。AC 映射
AUTO_MERGE_DISABLED置位路径被实测（真置位+读回+立即复位+时戳入档）；P0 dead-man trip：管家缺席，自动合并已停（AUTO_MERGE_DISABLED=true） #180 先例回归完成一次测试方法
bash governance/drill/tests/test-failclose.sh→ pass=6 fail=0（dry-run 路径）；真置位路径仅季度演练/显式FAILCLOSE_DRY_RUN=0触发风险与回滚
真置位窗口秒级且 trap 兜底复位；若复位读回失败，脚本显式输出人工复位命令并 fail。回滚：删脚本即停。
