Pull request overview
This PR introduces a new “patrol” service to continuously probe targets using three scenario sources (AC registry derivation, historical escape-pattern variants, and LLM-frontier + deterministic metamorphic checks), enforce machine-decidable oracles, dedupe by stable fingerprints, rate-limit issue creation, and support observation-bucket escalation plus “graduation” into CI regression tests. It also adds a scheduled GitHub Actions workflow to run patrol safely with a read-only posture and tightly scoped issue-writing permissions.
Changes:
- Add
pipeline/patrol/patrol.pycore engine implementing scenario generation, probe execution, oracle grading, fingerprint dedupe, throttling, observation escalation, yield/SNR downshift, and graduation. - Add demo target + exercise harness and a unittest suite to validate the key AC behaviors offline (no network / no real LLM).
- Add
.github/workflows/patrol.ymlto run selftests on PRs and run patrol only on schedule/manual with least-privilege permissions and artifact-backed state.

invariantoracle 通过eval(oracle["expr"], {"__builtins__": {}}, ctx)执行表达式。即使禁用 builtins，Python 的eval仍可能被表达式本身通过对象属性链等方式逃逸出沙盒，属于可执行代码注入面；而 AC 注册表/逃逸语料本质上是配置输入（未来接入多仓时很难假设其永远可信）。建议改为基于 AST 的受限表达式求值（仅允许 Name/Num/BinOp/Compare/BoolOp 等白名单节点与运算符），或使用明确的 DSL（例如只支持==,<,+,-等）来实现不变量校验。
if oracle["class"] == "invariant":
# 声明式不变量：受控 eval（语料经仓内评审，非外部输入；无 builtins）
ctx = dict(payload)
if isinstance(env.get("data"), dict):
ctx.update(env["data"])

cmd_run在写入本轮 runs 记录之前就调用了compute_metrics(state, policy)，因此输出的metrics["runs"]/yield_per_100_runs/probes_total等统计会漏掉当前 run（state.runs还没追加）。建议先append_jsonl(state.runs, ...)再计算 metrics，或让compute_metrics支持传入“当前 run”并纳入统计，避免 report.json/标准输出的指标与patrol.py metrics子命令口径不一致。

1. Unsafe invariant eval 🐞 Bug ⛨ Security
grade_payload 对 oracle.expr 直接 eval（仅清空 builtins）并且表达式来源于 YAML 语料/政策；这类“restricted eval”无法防止 Python sandbox escape，可能导致在 GitHub Runner 上执行任意代码并读取 GH_TOKEN/LLM_API_KEY 等环境变量。该风险同时会被毕业回归测试模板中的 eval 继承放大。
Agent Prompt
## Issue description
`patrol.py` uses `eval()` to evaluate invariant expressions from YAML (`oracle.expr`). Even with `{"__builtins__": {}}`, this is not a safe sandbox in Python and can be escaped to access objects, globals, and potentially perform arbitrary actions.
This is especially risky because patrol runs in GitHub Actions with tokens/secrets in the environment.
## Issue Context
- Invariants are currently defined in YAML (e.g., `escapes.yaml` includes an `expr` field).
- The runtime evaluates them via `eval()`.
- Graduation regression test generation also emits `eval()` into generated tests.
## Fix Focus Areas
- pipeline/patrol/patrol.py[382-395]
- pipeline/patrol/patrol.py[607-634]
## What to change
1. Implement a safe expression evaluator:
- Parse `oracle["expr"]` with `ast.parse(expr, mode="eval")`.
- Whitelist node types needed for invariants (e.g., `Expression`, `BoolOp`, `BinOp`, `Compare`, `Name`, `Constant`, `UnaryOp`, and specific operators like `Add/Sub/Mult/Div/Mod`, `Eq/NotEq/Lt/LtE/Gt/GtE`, `And/Or`).
- Reject any `Call`, `Attribute`, `Subscript`, `Lambda`, `Comprehension`, `DictComp`, `ListComp`, `GeneratorExp`, etc.
- Only allow variable names that exist in the prepared `ctx`.
- Evaluate by recursively interpreting the AST (do NOT call `eval`).
2. Update `grade_payload(... invariant ...)` to use the safe evaluator and to surface "expr-error" when the expression is invalid.
3. Update `_reg_check()` generation for `invariant` to use the same safe evaluator (e.g., embed a small safe evaluator helper in `REG_TMPL`, or avoid emitting expression evaluation entirely by snapshotting expected values where possible).
4. Add/adjust unit tests to ensure malicious expressions are rejected (e.g., attribute access / function calls) and return a controlled error (exit code 2/3 as appropriate).

2. Failed issues still dedupe 🐞 Bug ≡ Correctness
open_issue 在 gh 模式失败时返回 gh-error:* 字符串，但 _try_open 仍会把该指纹写入 fingerprints 台账，导致后续同指纹被去重而不再重试，从而永久丢失真实开单。该逻辑会在网络/权限/标签缺失等任何临时失败时触发。
Agent Prompt
## Issue description
When `issue_mode=gh`, `open_issue()` returns `gh-error:...` on failure, but `_try_open()` still appends the fingerprint to `fingerprints.jsonl`. This incorrectly marks the finding as opened, causing permanent dedupe and preventing retries.
## Issue Context
This will surface the moment policy flips from `draft` to `gh` or if `gh issue create` intermittently fails.
## Fix Focus Areas
- pipeline/patrol/patrol.py[536-554]
- pipeline/patrol/patrol.py[697-713]
## What to change
1. Change `open_issue()` to return a structured result (e.g., `{ok: bool, ref: str, error: str}`) or raise an exception on failure.
2. In `_try_open()`:
- If `issue_mode=draft`, keep current behavior.
- If `issue_mode=gh` and creation fails, do NOT append to `state.fp`.
- Instead return `("deferred", "open-issue-failed:...")` or `die(2, ...)` depending on desired fail-closed semantics.
3. Add/extend tests to cover the `gh` failure behavior (mock `subprocess.run` for `gh issue create` returning non-zero) and assert that the fingerprint is not recorded and will be retried next run.

3. State timestamp parse crash 🐞 Bug ☼ Reliability
opened_since 对 state.opened() 里的 ts 直接 datetime.strptime，遇到状态文件中任意一条时间戳损坏/格式变化会抛 ValueError 并让整轮巡逻异常崩溃（而不是按“状态不可信”走受控 fail-closed 退出码）。这会把一次 artifact 损坏放大为持续不可用。
Agent Prompt
## Issue description
`opened_since()` assumes `clock` and every `r["ts"]` in `fingerprints.jsonl` are valid ISO timestamps. If any record has a malformed `ts`, `datetime.strptime` raises `ValueError` and the process crashes with an unhandled exception.
## Issue Context
The PR explicitly treats state as a trust boundary ("状态不可信"), but current checks only validate JSON syntax, not required fields or timestamp formats.
## Fix Focus Areas
- pipeline/patrol/patrol.py[490-495]
## What to change
1. Wrap the `strptime` calls in `opened_since()` with `try/except ValueError`.
2. On parse failure, fail-closed using `die(3, ...)` with a message pointing to the offending record (repo, fingerprint, raw ts).
3. Consider validating `clock` format once in `cmd_run` when `--clock` is provided (bad input should exit code 2).
4. Add a unit test that writes a malformed `ts` into `fingerprints.jsonl` and asserts patrol exits with code 3 and a clear message.

4. Pr runs block scheduled patrol 🐞 Bug ☼ Reliability
workflow 顶层 concurrency.group 固定为 patrol，同时 workflow 也会在 pull_request 上运行 selftest；因此当有 PR 自测运行/排队时，会阻塞 schedule/manual 的巡逻执行，导致巡逻节奏被 PR 流量反向影响。该问题会直接降低 patrol 的可靠性与覆盖面。
Agent Prompt
## Issue description
Top-level `concurrency.group: patrol` applies to the whole workflow for all events. Because the workflow also runs on `pull_request`, PR selftests can queue/block scheduled/manual patrol runs.
## Issue Context
State collision concerns are specific to the `patrol` job (which restores/uploads `state/`). The `selftest` job does not use cross-run state and doesn't need to serialize with schedule patrol.
## Fix Focus Areas
- .github/workflows/patrol.yml[14-27]
- .github/workflows/patrol.yml[28-75]
## What to change
Option A (recommended): move concurrency to the `patrol` job only.
- Remove workflow-level `concurrency`.
- Add `concurrency` under `jobs.patrol` with `group: patrol`.
Option B: make concurrency event-scoped.
- Set `group: patrol-${{ github.event_name }}` so `pull_request` does not block `schedule`.
After change, ensure state directory collision is still prevented for schedule/manual runs.

守恒不变量用浮点 == 比较，999.99 变体产生 oracle 假阳性；现有测试恰好避开了该值。
根因：expr: from_after + to_after == from_before + to_before 是精确相等比较，而 amount_variants 含不可精确表示的浮点数。amount: 999.99 不触发 service.py 的隐性费用（fee 仅在 amt > 1000 时为 1），本应守恒，但 IEEE754 下两侧相差约 5e-13 → eval 返回 False → 报告 invariant 违约。
该假阳性的 symptom 是 "violated:" + expr，与真违约完全相同，所以指纹相同，人工判定时无法区分真假 bug。
各站点需要的修改：
pipeline/patrol/demo-target/escapes.yaml#L19-L22：把expr改成容差比较。因为grade_payload的eval用{"__builtins__": {}}，abs不可用，请用链式比较：expr: -1e-9 < (from_after + to_after) - (from_before + to_before) < 1e-9。pipeline/patrol/tests/test_oracles.py#L65-L70：test_invariant_clean_boundary只用amount: 1000（精确整数）。请把999.99加入干净断言，作为浮点假阳性的回归钉。修改前该断言必须红，修改后转绿——这正好验证了修复有效。

探针执行未捕获 OSError，会让整轮巡逻带裸 traceback 崩溃。严重级：中。
subprocess.run 只捕获 subprocess.TimeoutExpired。若 service 路径不存在或不可执行，subprocess.run 抛 FileNotFoundError（OSError 子类），异常穿透 cmd_run 直达顶层。
该路径可达：cmd_run 第 726-727 行只做路径拼接，不校验 service 是否存在。政策里的相对路径与 --target-base 组合出错时（工作流中的常见误配），巡逻不会输出文件头声明的「非零退出 + 明确原因」，而是抛 Python traceback，且已生成的 finding 全部丢失。

eval 的信任边界应随语料来源收紧。严重级：中（当前不可利用）。
{"__builtins__": {}} 不是沙箱。表达式仍可经 ctx 中对象的属性链取回内置类型并执行任意代码。当前语料是本仓评审过的 YAML，威胁模型成立，注释也说明了这一点。
风险在未来：第 3-4 行注释声明「生产接入=各仓 quality/ 的 AC UID 落到本形态」。一旦 AC 注册表来自被巡逻的目标仓，expr 就变成跨仓输入，而 patrol 运行在有 gh 凭据的 CI 里（issue_mode: gh）。那时 eval 成为 RCE 面。
建议在接入跨仓语料之前，把 expr 换成受限求值：用 ast.parse(expr, mode="eval") 白名单节点类型（Compare、BinOp、Name、Constant、BoolOp、UnaryOp），拒绝 Attribute、Call、Subscript。这与「五类 oracle 闭集」的设计意图一致——不变量表达式不需要属性访问和函数调用。

gh 开单失败被当作开单成功，指纹台账会永久吞掉真 bug。严重级：高。
第 552-553 行在 gh issue create 返回非零时返回 f"gh-error:{...}"，而不是把失败向上传播。_try_open（第 707-713 行）无条件把该返回值当作 issue_ref 写入 fingerprints.jsonl，并返回 "opened"。
后果链：
gh因限流、权限不足或网络故障失败。- 指纹进入台账，线上没有 issue。
- 后续每一轮 run，
_try_open第 702 行的去重命中该指纹，直接返回"deduped"。 - 该真 bug 再也不会开单，且
compute_metrics把它计入issues_opened，压低 SNR，可能误触发降频。
此外，gh 二进制缺失抛 FileNotFoundError，timeout=60 抛 TimeoutExpired，两者都未捕获，会让整轮巡逻崩溃。

observation 升级的场景 payloads 为空，一旦毕业会生成恒绿的回归测试，违反 fail-before。严重级：中。
第 806 行用 _mk("obs", "llm-metamorphic", [], {"class": "invariant"}, ...) 构造场景，payloads 是空列表。_try_open 第 710 行把 scenario["payloads"] 写入 fingerprints.jsonl。
若该指纹之后被判定 reproduced 并执行 graduate，emit_regression_test 生成的测试里 PAYLOADS = []，REG_TMPL 中 for p in PAYLOADS: 循环体不执行，test_oracle 直接通过。
结果：毕业回归测试恒绿。它既不钉住缺陷，也无法在缺陷修复后提供保护，与 REG_TMPL 文档字符串声明的「缺陷修复前本测试必须红」和 ADR-0061 直接冲突。test_graduation.py 只覆盖了 ac-AC-DEM-2，没有覆盖 observation 升级出来的指纹，所以自测不会发现。
两个可选方向：
- 把 observation 的
payload（第 801 行已有s.get("payload")）填入场景payloads，让回归测试有实际探针。 - 在

使重复 graduate 幂等，避免污染毕业审计。
当前虽然会去重 corpus-state.json，但每次调用仍会生成回归测试并向 graduations.jsonl 追加记录。同一指纹重复毕业会造成重复审计条目；现有测试只检查第二次命令成功，无法发现该问题。

test_oracles.py含逐类负控制矩阵：已知违约样本必须被抓，ADR-0065 风险缓解条款）；observation 独立性=不同 run 且不同 seed（test_observation.py：两次独立升级 / 同 seed 不同 run 不升 / 同 run 不同 seed 不升 / 升级后同指纹去重）。演习证据：run demo-2 中 observation 第二次独立出现 → 升级开单。test_fingerprint_dedupe.py三轮 run 收敛到零新开单 + 台账零重复；频控每小时/每日上限来自.github仓governance/policy/patrol.yaml（test_throttle_downshift.pyrun 级 deferred 断言）。patrol.py verdict（ADR-0064 三值）→patrol.py graduate：输出回归测试文件（fail-before：演习中生成的test_ac-AC-DEM-2.py对带缺陷靶场断言红AssertionError: 500 not less than 500 : 不得 5xx）+ 场景从语料移除（run demo-2 起 ac-registry 场景 4→3）；非 reproduced 毕业被拒（test_graduation.py）。patrol.py metrics输出每百次唯一真 bug 数/开单复现存活率/信噪比；SNR（最近 20 张开单窗口）< 0.05 → 自动降频（收敛到 1 单/日而非停巡）+ needs-human，窗口恢复自动解除（test_throttle_downshift.py触发/解除/样本不足不误触）。三源场景（ADR-0065 决策 1）
(a) AC 注册表派生：
ac-registry.yaml把 AC 文本映射为机器可判定探针，逐条声明 vs 实际行为对账；(b) 历史逃逸模式攻击语法：escapes.yaml逃逸模式参数化生成变体再攻击（seed 驱动确定性采样）；(c) LLM 前沿探索+metamorphic：LLM 半边经pipeline/metering/metering-wrapper.sh（ADR-0062 一次 invoke 恰一条聚合记录，验链断言见test_llm_degrade.py），无凭据时诚实降级（llm_status=skipped-no-creds计数，不伪装生成过——test_llm_degrade.py）；metamorphic 半边确定性恒跑（交换律等价变换抓到靶场播种缺陷）。演习实录（AC-1/AC-3 证据；issue_mode=draft 零线上开单，artifact 即证据）
