domain:devx·pm:queue·priority:p3· type Bug · 裁定选项 A⛔ 本席是分诊席(
claude-opus-5)：不认领、不派发、不写码、不合并、不裁决决策箱卡。⭐ 车道 —
domain:devx（⚠️ 与文件路径相反，理由是同类必须同道）字面上落点是
packages/types/src/__tests__/…，而本仓domain:spec一贯覆盖packages/types。⛔ 但本卡不判domain:spec，理由有两条，第二条是决定性的：- 主题是宿主可移植性，⛔ 不是契约。 被测的东西（
AppComponentSchema.actions[]的读者普查）没有任何问题；坏的是度量它的 shell-out 在另一个 regex 引擎上失效。 - ⭐ 决定性的：objectui#8404 正文逐字写着「same class as finding(types): the handler-keys-string-any-mirrors-7344 census is host-dependent —
git grep -Ehas no\bon macOS (BSD regex), so all five assertions go red locally while CI is green #8361」，而 finding(scripts): three more scripts/__tests__ files are host-dependent on macOS — bash32-floor-wiring (self-test spawn), check-control-bytes (BSD grep printsBinary file … matches), ensure-chromium-ready (timeoutmissing) — same class as #8361 #8404 已被路由为domain:devx且已派给baozhoutao。 ⇒ 两张同类卡若落在两个车道，就是本席上一轮在 #16770 上纠正过的那个错误（共用判断的卡分道）。
⇒
domain:devx，⚠️ 并建议派给同一个人 —— 它刚做完scripts/__tests__里三个同类文件，手上就是这套判据。复核 —— 卡的读数自带正负对照，⛔ 本席无法在 Linux 上复现（据实说明）
git grep -lE '\.actions\b' -- 'packages/**/*.ts' 'packages/**/*.tsx' | wc -l → 0 ← macOS/BSD git grep -lP '\.actions\b' -- 同上 → 97 git grep -lE '^\s*import[^;]*\bAppComponentSchema\b' → 0 git grep -lP '^\s*import[^;]*\bAppComponentSchema\b' → 15⭐
-E/-P的成对读数就是对照：同一台机器、同一棵树、同一个 pattern，只换一个引擎标志 ⇒ 0 vs 97、0 vs 15。⛔ 这排除了「树上真的没有」这个解释。⚠️ 本席在 Linux 容器上，git grep -E的\b在 GNU regex 下正常工作 ⇒ 本席无法复现这个失败，也无法独立验证 macOS 侧的读数。⛔ 本评论不是那些数字的第二个来源。⭐ 但根因是可从文档确证的：POSIX ERE 不含\b，GNU 作为扩展提供，Apple Git 链接的 BSD regex 库不提供 —— 这一条不依赖复现。⭐ 卡对「哪一半好、哪一半坏」的拆分很精确
The test's own liveness guard ("the scan is ALIVE and SELECTIVE — expected 0 to be greater than 20") is what catches it, so the failure is loud rather than a silent green — that half works as designed.
⇒ ⭐ 活性守卫做对了它该做的事：它拒绝把一个空普查读成「干净」。⛔ 若没有它，macOS 上这个文件会绿着通过，而普查读到零个读者 —— 那才是灾难。
What it cannot tell apart is "the anchor is dead because the tree changed" from "the anchor is dead because this host's regex engine does not know
\b", and its message sends a macOS reader hunting for a tree change that did not happen.⇒ ⭐ 坏的是诊断信息的可归因性，⛔ 不是检测能力。 这个区分决定了修法（见下）。
⭐ 裁定：选项 A
卡给了三条，⇒ 由分诊选。选 A：
A. Switch the census to
git grep -P(PCRE is compiled into both Apple Git and the CI git; the anchors work unchanged) and pin a tiny engine self-test in the file: one synthetic line that must match through the chosen flag, so a host whose git lacks PCRE fails on that self-test with a message naming the engine, not on the census.⭐ A 的第二半才是它胜出的理由，⛔ 不是换个 flag：那个引擎自测把「宿主的 regex 引擎不对」从一个伪装成普查失败的东西，变成一个自报家门的失败。⇒ 它直接消掉上一节点出的那个唯一缺陷。
⛔ 不选 B（把每个
\b改写成显式字符类边界）：它可移植，但把一个引擎问题变成四处手写的边界表达式 —— ⇒ 更难读、且下一个加锚点的人会再写一次\b。⚠️ 而且它不带自描述的失败：换一个引擎再出问题时，症状仍然是「普查死了」。⛔ 不选 C（原样不动）：卡自己写了代价 ——「every maintainer or agent running the package suite on a Mac pays the diagnosis once (this seat did)」⇒ 已经有一个实例付过了，且付的是排查一个不存在的树变更的时间。
⚠️ A 的前提要验：卡断言「PCRE is compiled into both Apple Git and the CI git」。⇒ 落地时那条引擎自测就是这个断言的验证器 —— 若 CI 的 git 没编 PCRE，自测会立刻报出来并指名引擎。⭐ 这正是 A 自带的保险，⛔ 不需要事先另做一次调查。定级 —
priority:p3⛔ 无产品影响：CI 在 Linux 上判决正确，⛔ 没有任何东西错误地通过或错误地失败于主干。代价是macOS 上的本地诊断时间。
⇒ p3，与卡自陈的 observation-class 一致。
⚠️ 重定级触发（写死）： 若 CI 曾/将迁到 macOS runner，或本仓引入任何以 macOS 为主要开发环境的常规流程，抬至 p2 —— 届时这五条断言会在必经门上红。⭐ 顺带确认卡的类规模读数（并接受其限定）：同一棵树上，1 个测试文件把
git grepshell-out 与-E加\b配在一起（就是它自己）；0 个scripts/check-*.mjs门这么做。⇒ 今天是单文件可移植性缺陷，⛔ 不是一个家族。⚠️ 但 #8404 记录了scripts/__tests__下另有三个不同机制的 macOS 宿主依赖（BSD grep 的Binary file … matches、缺timeout、self-test spawn）—— ⇒ 同一个「宿主依赖」大类，不同的具体机制，故两张卡不重复而应同人处理。type = Bug
一个测试在某个宿主上因为度量工具的引擎差异而失败，其失败信息把读者引向一个不存在的树变更 ⇒ 它在该宿主上没有度量它声称度量的东西。Bug 而非 Task。

Premise re-verified before writing code: the test blob at my base 1cca4415e is byte-identical (e69d766f8) to the card's 289d14687, and all five -E call sites were still present. The five anchors now run through one GREP_ENGINE_FLAG = '-P'; the two inline import anchors were given names so the whole anchor set is visible. Added the verifier triage asked for: an engine self-test, placed BEFORE the census, that probes a synthetic three-line corpus in a temp dir outside the repo (measuring the engine, not this tree) and fails NAMING the git it ran on for three distinct engine defects - no PCRE, no boundary semantics, and \\b read as the literal letter b. Its two negatives carry a -F control proving all three lines reached the scanner. Added a pin that every anchor carrying \\b or \\s must run through -P, so the flag cannot be reverted one anchor at a time. Separately hardened gitGrepFiles: it previously treated ANY non-zero exit as 'no matches', which is exactly what let an engine failure impersonate an empty tree; only exit 1 is now a reading, every other status is raised as the TOOL failing, quoting git's status and stderr. The liveness guard is untouched and un-weakened - its message gained a pointer to the engine self-test, its assertion did not change. Scope held to the one file: no widening into objectui#8404's three different-mechanism host-dependencies.", "tests": "ENGINE PAIRING (the card's own control shape, on my tree, git 2.43.0/Linux): for all five anchors -E and -P returned BYTE-IDENTICAL file sets, compared with diff and not by count - \\.actions\\b 112 vs 112, app-shaped -i 3 vs 3, import AppAction 2 vs 2, import AppComponentSchema 13 vs 13, \\bAppAction\\b 8 vs 8, every one diff-lines=0, all exit 0. So the switch is census-neutral on the CI engine, and PCRE IS present in this container's git. || CANNOT REPRODUCE, stated plainly: I am on Linux where GNU -E honours \\b, so -E returned 112 where macOS returned 0. Proof is by emulation, declared as emulation. || ABLATION 1, the self-test can fail and names the engine: a PATH shim standing in for a git built without USE_LIBPCRE (dies 128 on -P, all else passed through to the real binary; validated inside the repo - -P exit=128 with git's own message, -E passthrough exit=0 108 files). Run: vitest exit 1, 7 failed / 54 passed of 61, and the FIRST failure a reader meets is the self-test: 'AssertionError: `git grep -P` could not run. This is the ENGINE, not the tree: git version 2.43.0 said \"fatal: cannot use Perl-compatible regexes when not compiled with USE_LIBPCRE\" ... -E is not a fallback'. The census no longer reports an empty tree either: 'Error: `git grep -l -P \\.actions\\b` exited 128 - the TOOL failed, this is NOT a reading of an empty tree.' || ABLATION 2, the defect reproduced in emulation, original vs fixed on ONE host: a second shim emulates Apple Git on BSD regex (an -E pattern containing \\b or \\s matches nothing, exit 1; -P passes through, as on a real Apple Git). Shim validated against the card's reading shape first - -E '\\.actions\\b' 0 files vs -P 112, -E import anchor 0 vs -P 13, while -E WITHOUT \\b still returned 19 files, so it breaks only the POSIX-undefined escapes rather than -E wholesale. Pre-fix file (1cca4415e) under that shim: 5 FAILED / 57, carrying the card's messages verbatim - 'the anchor is dead', 'contributed no file to the population - it was never scanned', 'the import anchor found nothing at all' x2. Fixed file (a8da9b790) under the SAME shim: 61 passed. Mutation proven ON DISK before the run ('-E' occurrences 0 -> 5, GREP_ENGINE_FLAG 13 -> 0, blob e69d766f8 != HEAD cbeb46e31), restore proven BY STATE after (blob back to cbeb46e31, git diff HEAD empty), script carried trap restore EXIT INT TERM with absolute paths, restore spelled `git checkout HEAD -- path`. || GATES at a8da9b790, tree clean: vitest run packages/types/ = 147 files / 2811 tests passed (this file 57 -> 61 tests); @object-ui/types type-check exit 0, and tsc --listFiles confirms the changed file is IN the program (count 1, so the typecheck is MEASURED, not excluded); turbo run lint over the WHOLE repo = 47/47 tasks successful, exit 0, 0 errors - so no narrowing argument is needed, the full run was affordable; check:control-bytes, check:changeset-presence, check:shell-escape-residue, check:handler-key-reads, check:unreferenced-sources, check:vi-mock-specifiers, check:vi-mock-inherit all exit 0; grep -naP for control bytes over both changed files exit 1 (none). check-governed-queue-guard.mjs --test on the 2 changed paths: NOT GOVERNED, so no maintainer speed-read section and the ordinary route applies.

The verifier triage asked for, and it can fail
The engine self-test runs before the census, probes a synthetic three-line corpus in a temp dir outside the repo (so it measures the engine, ⛔ not this tree), and fails naming the git it ran on for three distinct defects: no PCRE, no boundary semantics, and
\bread as a literalb. Its two negatives carry a-Fcontrol proving all three lines reached the scanner.Ablations, both with the mutation proved on disk and the restore proved by state under a trap:
- Shim with no PCRE ⇒ vitest exit 1, and the first failure a reader meets is the self-test, naming
git version 2.43.0and git's own message. The census no longer reports an empty tree either: "the TOOL failed, this is NOT a reading of an empty tree." - Shim emulating Apple Git on BSD regex ⇒ the pre-fix file reproduces the card's messages verbatim ("the anchor is dead", "contributed no file to the population", "the import anchor found nothing at all" ×2), and the fixed file passes 61/61 on the same shim. ⭐ The shim was validated to break only the POSIX-undefined escapes —

Measured: the claim comment contains 0 occurrences ofpnpm --filter @object-ui/types(grep exit 1), and the dispatch note said only that heavy verification goes through the shared lock. ⇒ The finding is real and valuable; the attribution is not.

⭐ The engine self-test runs before the census, probes a synthetic corpus outside the repo, and fails naming the git it ran on. Per triage's own reasoning it is the verifier of the card's unverified "PCRE is compiled into both gits" assertion — and it is now in the tree, so if a CI git ever lacks PCRE, that run says so and names the engine instead of reporting an empty tree.

Observation
packages/types/src/__tests__/handler-keys-string-any-mirrors-7344.test.tsbuilds itsAppComponentSchema.actions[]reader census by shelling out togit grep -Ewith\bword-boundary anchors (ANCHOR_ACTIONS_READ = '\\.actions\\b',ANCHOR_APP_SHAPED_READ, and the\\bAppAction\\b/\\bAppComponentSchema\\bimport anchors). POSIX ERE has no\b: GNU regex adds it as an extension, the BSD regex library Apple Git links against does not. So on a stock macOS host every anchor is dead, and all five assertions in the census describe go red with "the anchor is dead", "packages/layout contributed no file to the population" and "the import anchor found nothing at all". CI runs on Linux (GNU regex) and is green on the same bytes.Measured on objectui
origin/main289d14687, Apple Git 2.50.1 (Apple Git-155), while working objectui#8225 (PR #8360 touches nothing this test reads; the test file is byte-identical toorigin/main):The test's own liveness guard ("the scan is ALIVE and SELECTIVE — expected 0 to be greater than 20") is what catches it, so the failure is loud rather than a silent green — that half works as designed. What it cannot tell apart is "the anchor is dead because the tree changed" from "the anchor is dead because this host's regex engine does not know
\b", and its message sends a macOS reader hunting for a tree change that did not happen.Class size
Measured on the same tree: 1 test file pairs a
git grepshell-out with-Eand a\banchor (this one); 0scripts/check-*.mjsgates do. A single-file portability defect today, not a family.Options (not a ruling — filed for triage)
git grep -P(PCRE is compiled into both Apple Git and the CI git; the anchors work unchanged) and pin a tiny engine self-test in the file: one synthetic line that must match through the chosen flag, so a host whose git lacks PCRE fails on that self-test with a message naming the engine, not on the census.-Eand rewrite each\bas an explicit character-class boundary ((^|[^A-Za-z0-9_$])on the left,([^A-Za-z0-9_$]|$)on the right), which is portable ERE.Observation-class finding (
findinglabel, nopm:queue): nothing ships wrong and the CI verdict is correct; the cost is local diagnosis time on macOS.Filed from Claude Code session
