高严重级别：保留目录名边界，避免绕过审计。
for d in $(...) 会按空白字符拆分目录名。PR 可添加 specs/foo bar/spec.md。循环会检查 foo/spec.md 和 bar/spec.md，而不会检查实际的 foo bar/spec.md。随后工作流会写入 EXPECTED_SKIP success check，绕过该 spec 体的 adversary 审计。
使用 JSON 结构化处理完整路径。不要通过命令替换、换行或 shell 词拆分传递目录名。调用 Contents API 时也必须对路径段进行 URL 编码；无法安全解析时应 fail-closed。

2. Canonical spec bypasses audit 🐞 Bug ≡ Correctness
The predicate considers only spec.md, so changes to the signed canonical body specs/IR-0003/constitution.md are classified as adjacent and receive a successful adversary check. This bypasses the repository rule requiring red-team review for spec/test-design changes.
Agent Prompt
## Issue description
The adjacent predicate exempts `specs/IR-0003/constitution.md`, although that file is the signed canonical IR-0003 body.
## Issue Context
Auditable bodies are not universally named `spec.md`; the repository already contains a canonical `constitution.md` with an associated suite.

- specs/IR-0003/constitution.md[1-7]

3. Spec deletion gets skipped 🐞 Bug ⛨ Security
Deleting or renaming away specs/<dir>/spec.md makes the head-tree lookup return missing, which classifies the contract removal as adjacent and writes a successful EXPECTED_SKIP check. A PR can therefore remove an auditable spec body without supplying a survived adversary audit.
Agent Prompt
## Issue description
A deleted or renamed-away `spec.md` is absent from the head tree and is therefore incorrectly treated as a non-auditable adjacent directory.
## Issue Context
The decision must account for changed-file status and the base tree, not only existence on the PR head. Any deletion or rename of an auditable body must remain on the full audit path.

4. Lookup failures fail open 🐞 Bug ☼ Reliability
Every failed per-directory contents request—including rate limits, permission errors, and transient GitHub failures—is interpreted as proof that spec.md does not exist. If all lookups fail, the workflow grants a successful adjacent skip instead of preserving the stated fail-closed behavior.
Agent Prompt
## Issue description
The contents lookup conflates an exact not-found response with every operational/API failure, allowing failures to produce a green check.
## Issue Context
Only a confirmed 404 may establish absence. Authentication, rate-limit, transport, server, and malformed-response failures must set `has_specs=true` or fail the job.

5. Whitespace paths bypass audit 🐞 Bug ⛨ Security
for d in $(...) applies shell word splitting to directory names, so a valid path such as specs/foo bar/spec.md is checked as nonexistent directories foo and bar. The workflow then labels the actual auditable directory adjacent and emits a successful skip.
Agent Prompt
## Issue description
Shell word splitting corrupts specs directory names containing whitespace, allowing an auditable body to be misclassified as adjacent.
## Issue Context
Preserve each filename/directory as an exact value, preferably by emitting NUL-delimited records or performing the classification in Python; also safely encode the path used for the API request.

摘要
adversary-gate 的 specs/** 谓词精化：命中只统计可审计 spec 体（变更路径所属
/ 在 PR head 上存在 spec.md——adversary 目标契约specs/
specs//{spec.md,suite/,run-suite.sh} 的判别面）。无 spec.md 的 specs/ 目录
（如 AI_Web_School specs/test-freeze 的 MANIFEST.sha256 哈希账本）是机器可校验
派生资产，非红队审计对象——完整性由自身哈希链执法。此类"specs 邻接变更"按
EXPECTED_SKIP 写 success check 放行。
变更路径选择
diff 路径 + PR head 树的 spec.md 存在性派生，无人工标注介入；
每波次重签的常态资产，逐 PR 登记豁免不可持续，且逐仓清单漂移面更大；
spec 体变更须 survived、merge_group 人工核均不变。
触发实例
AI_Web_School#169（specs/test-freeze/MANIFEST.sha256 重签）：原谓词
startswith("specs/") 误伤——该目录无 spec.md，adversary 攻击预检即 exit 2
（目标契约不成立），PR 永无 survived 通道，恒红无解。

Summary by CodeRabbit
spec.md时，才会按规范变更进行审计。spec.md的附属文件变更将标记为可通过检查，减少不必要的拦截。specs/根目录下的文件仍会按可审计变更处理。
