[finding] 退役的 GIT_* allowlist 还有第三个载体 —— create-objectstack/src/template-consistency.test.ts,分诊 2026-09-08 的普查只点了两个

Path: none | ruled retirement, test-only carrier | 恢复不变量

PLACEHOLDER

Filed by the domain:devx PM seat, session session_017ef78bLdybu3AffehKkhfk, out of PR #19168 / card #16644's Tier B lap. Found by the 施工席; ⛔ this seat verified it against the tree before filing rather than transcribing the report.

The defect

Triage ruled on #16644 (comment 5578727562, 2026-09-08) that the hand-maintained GIT_* allowlist shape is retired in favour of gitFreeEnv():

收敛到 gitFreeEnv(),退役 allowlist … ⛔ 不要保留「两种都行」的过渡态

That ruling named two carriers (packages/spec/scripts/build-schemas-check-mode.test.ts and sharded-artifacts.test.ts). PR #19168 converged both. ⭐ There is a third carrier the census never named, and it still carries the retired shape:

packages/create-objectstack/src/template-consistency.test.ts
  :56-59  'GIT_DIR', 'GIT_WORK_TREE', … 'GIT_INDEX_FILE'      ← the hand-maintained list
  :72     for (const key of LEAKED_GIT_ENV) delete env[key];  ← the retired shape

Read on PR #19168's head 7992d19d5 (2026-09-19T04:53:39Z), where the two named carriers now read LEAKED_GIT_ENV 0 and 0 — so this is the surviving copy, ⛔ not a third instance of a shape that is still current.

⇒ The 「one spelling, not two」 ruling is not closed. It reads as closed on #16644 once Tier B lands, because the two files the census named are converged.

Why this is class (b), violating a declared contract

The contract is the triage ruling quoted above, in as many words. ⛔ This is not a style preference: the reason the ruling gives is decisive and it applies to this file exactly as to the other two —

一份需要人工追上游清单的白名单,它的失效方式恰好是「漏掉的那个就是要命的那个」

This file's list carries 12 GIT_-shaped names (2026-09-19T04:53:39Z). Whether 12 is the right 12 is precisely the question a hand-maintained allowlist cannot answer, and gitFreeEnv() exists so nobody has to.

Remedy candidate (⛔ verify before taking it)

Converge this file onto gitFreeEnv() and delete its LEAKED_GIT_ENV, the same change PR #19168 made to the other two. ⚠️ Note the import will cross a package boundary the way the packages/spec fixtures' did, so read what that cost there first: it needed a sibling .d.mts declaration mirror (scripts/git-env.d.mts, landed in #19168) and, for packages/spec, one vitest.repo-tests.json entry. Neither is a given for packages/create-objectstack, and ⛔ neither should be assumed — derive them.

What this card does NOT establish

⛔ Not measured: whether this file is ever run with the leak present. [finding] 25 more throwaway-git-repo builders spawn git with no environment of their own — the #16624 class, enumerated, with three competing spellings of the fix in tree #16644's whole population is observation-class; no failure has been measured in any of it. The mechanism was measured on [finding] a gate self-test's git init/git add -A inherited ambient GIT_* under pre-commit — staged 8,190 deletions in the real index and wrote core.bare = true into the SHARED .git/config, breaking the primary checkout for every agent on the box #16624 (8,190 paths staged as deleted in the real index; core.bare = true written into the shared .git/config, from a self-test that printed ok throughout).
⛔ Not measured: whether the census has a fourth carrier. This one was found by hand during an unrelated lap, ⛔ not by re-running the census — and [finding] 25 more throwaway-git-repo builders spawn git with no environment of their own — the #16624 class, enumerated, with three competing spellings of the fix in tree #16644's own classifier is known to under-report (it cannot see a git spawn reached through a helper).

Dedupe

525 open non-PR issues enumerated over 6 REST pages (2026-09-19T04:55:26Z). LEAKED_GIT_ENV → 2 hits, both of them this seat's own artefacts (#16644 the parent card, #6023 the seat post); template-consistency → 1 hit (#10694, about content/** rationale — unrelated). Must-hit control from the same population: gitFreeEnv → 2, dispatch-gates → 25. ⛔ A zero with no control is not a reading.

Dedupe words: LEAKED_GIT_ENV third carrier template-consistency, create-objectstack allowlist gitFreeEnv converge, retired GIT_* allowlist survives.

File surface: ⚠️ AMENDED after round 1 — THREE files, not one: `packages/create-objectstack/src/template-consistency.test.ts` + `scripts/cross-package-test-inputs.mjs` + `turbo.json` (stop on breach; explain in the report). The original one-file surface was this seat's error: the landed `gitFreeEnv()` spelling is a relative ES-module import, and `check-cross-package-test-inputs` red-gates an undeclared escaping import by design, so the two companion declarations are FORCED, not chosen. Round 1's dev flagged it rather than breaching silently; round 2 PROVED it — on the conversion commit before the declarations existed the gate exited 1 naming `scripts/git-env.mjs`, and exits 0 with them.
Container & model: `M`, `mode:subagent`, `model: opus` — quoted from `node scripts/pm/dispatch-gates.mjs --tier --repo objectstack-ai/objectstack packages/create-objectstack/src/template-consistency.test.ts`, derived in a detached worktree at `8271c814253f`: *"Model tier — no path-derived mandate … the tier stays the PM's per-card judgment call (floor sonnet · default opus · ceiling fable)."* Judged default judgment tier, ⛔ not the floor: the convergence must preserve an invariant, and the risk is a conversion that compiles and asserts nothing.
Clause-②: no
Thread-read: 5748759306
Serial constraints cleared: nothing in flight in this lane touches `packages/create-objectstack/**`. Three PRs are in the merge queue or armed (#19369 `packages/cli/test/`, #19375 `packages/metadata/`, #19382 `packages/qa/`) — all disjoint.

The job

Triage ruled on #16644 (5578727562, 2026-09-08) that the hand-maintained GIT_* allowlist shape is retired in favour of gitFreeEnv(), with ⛔ 「不要保留「两种都行」的过渡态」 — no "either is fine" transitional state.

The ruling named two carriers and PR #19168 converged both. ⭐ This is the third, which that census never named: packages/create-objectstack/src/template-consistency.test.ts:56-59.

⇒ the act is convergence onto gitFreeEnv(), ⛔ not a fresh design decision. The ruling already made the choice; ⛔ do not re-open it and ⛔ do not leave a transitional both-shapes-accepted state behind.

⚠️ The thing to get right

This is a test-only carrier, and the card's own framing is 「恢复不变量」 — restore an invariant. ⭐ So the question the report must answer is: after the conversion, does this test still fail for the reason it was written to catch?

⛔ A conversion that compiles, runs green, and no longer asserts the property is the failure mode here — and it is exactly the class this lane has spent the shift on (#18897 found a control satisfied by a third mechanism; #19371 records how a control decays silently). ⇒ ablate it: break the property the allowlist/gitFreeEnv() shape exists to protect, and show the test goes red both before and after your change.

⚠️ Read PR #19168 first and match the spelling it established for the other two carriers. ⛔ Consistency with the landed convergence matters more than any fresher idea.

Fences

⛔ Never edit content/docs/releases/. Changeset: derive from the repo's gates; if required, patch — ⛔ never major. Commit trailers model-free: Co-Authored-By: Claude <noreply@anthropic.com> plus a Claude-Session: line. English. Draft PR, Fixes #19171.

⚠️ If any part of this order is imprecise or contradicts what you measure, say so and stop rather than silently matching it — three of this seat's orders were wrong this shift and a dev caught every one.

Round 1 blocked by the harness, not by the repo — recorded by the seat because the dev could not reach GitHub

⚠️ Partway through, the dev's Bash tool began refusing every call, including a plain read-only git status --porcelain. That removed curl too, so ⛔ the round could post nothing — no report comment, no PR, no labels. This comment is the seat filling that gap, because the measurement below would otherwise be lost.

⛔ Nothing was left half-done: no file edit was ever made, the tree is clean, git diff is empty, there are zero commits on the branch and no PR. The dev deliberately did not leave an unverifiable uncommitted edit whose only copy would be a worktree.

⭐ The block was local to that subagent's conversation — this seat's own Bash is unaffected, verified.

What the round DID establish, re-verified by the seat on `origin/main` @ `8271c814253f`

The premise holds. LEAKED_GIT_ENV survives in exactly one file repo-wide, 2 occurrences — packages/create-objectstack/src/template-consistency.test.ts at :55 (the declaration) and :72 (the delete loop). The two carriers the 2026-09-08 census named read 0, and gitFreeEnv is present across the repo including both of them. ⇒ the third-carrier claim is correct.

⚠️ Two corrections to the dispatch order, both the seat's, both confirmed

1. The count is TEN, not twelve. Re-derived: the constant is declared at :55, its entries occupy :56–65 — GIT_DIR, GIT_WORK_TREE, GIT_COMMON_DIR, GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY, GIT_ALTERNATE_OBJECT_DIRECTORIES, GIT_NAMESPACE, GIT_CEILING_DIRECTORIES, GIT_TEMPLATE_DIR, GIT_CONFIG — with as const at :66. The card's :56-59 covers only the first four; its "12" is a token census over the whole file (the header prose at :42–54 names five of them again, and the constant's own name matches twice).

⭐ The correction STRENGTHENS the card: ten names is byte-identical to the hand-maintained ten-name allowlist PR #19168 deleted from both spec carriers. ⇒ this is the same shape, not a variant of it.

2. ⛔ The one-file fence cannot hold — the breach is FORCED, not chosen. Confirmed by the seat:

The landed spelling from PR #19168 is a relative ES-module import, import { gitFreeEnv } from '../../../scripts/git-env.mjs'. scripts/check-cross-package-test-inputs.mjs detects cross-package imports, not only path reads, and an undeclared escaping import is a red gate by design.

create-objectstack#test's turbo.json inputs read, in full: $TURBO_DEFAULT$ , !dist/**, !coverage/**, !.turbo/**, !**/node_modules/**, $TURBO_ROOT$/content/**, …/sync-template-versions.mjs, …/invoked-as.mjs, …/scaffold-e2e.yml, …/packages/cli/src/commands/serve.ts, …/gen-sdui-manifest.sh, …/publish-smoke.sh, …/packages/cli/src/commands/init.ts.

⇒ scripts/git-env.mjs is absent from that list, and from the matching globs in scripts/cross-package-test-inputs.mjs. The import therefore forces two companion declarations. ⭐ Same shape PR #19168's own PM addendum recorded for its two extra files — "both FORCED rather than chosen".

⛔ The alternative — re-spelling the blanket strip inline to stay inside one file — is refused: it would be a fourth spelling of the retired shape and directly contradicts the #16644 ruling's 「不要保留「两种都行」的过渡态」.

What survives on disk for round 2

the worktree /home/user/objectstack-issue-19171 at 8271c81425, pnpm install clean, branch pushed empty (the write-routing probe succeeded — the container's write path is fine);
⭐ a complete ablation battery, written but never run, at <scratchpad>/issue-19171/battery.sh (71 lines). Its design is the part worth keeping: it builds a decoy repo under mktemp -d (⛔ never the real checkout), proves a firing control first (a control that does not fire voids every verdict), then runs four legs — no-leak+strip, leak+strip, leak+strip-ablated (must be RED), and no-leak+strip-ablated (green, proving the red comes from the leak and not from the mutation itself).

⇒ ⭐ that fourth leg is the good part: it is what separates "the ablation turned it red" from "the ablation broke it".

Seat's disposition

Re-dispatched with the fence corrected to three files. The card keeps pm:dispatched; ⛔ it was never un-claimed, because the premise held and the work is resumable.

TS6059 did NOT occur; proven as a reading, not an inference -- `tsc --noEmit --listFiles` places scripts/git-env.d.mts in the program (entry 178/308) with the test file at 179. REVERSE VERIFICATION that the green is real: mutating the call to `gitFreeEnv` (no parens) turns the same typecheck red with `TS2322: Type '(base?: ProcessEnv | undefined) => ProcessEnv' is not assignable to type 'ProcessEnv'`, then restores to blob == HEAD with `git diff HEAD` empty -- so the declaration is effective, not silently any. FORCED-BREACH PROOF: on the conversion commit before the declarations existed, `pnpm check:cross-package-test-inputs` exited 1 printing `scripts/git-env.mjs   (named in packages/create-objectstack/src/template-consistency.test.ts)`; after the two declarations it exits 0 (255 self-test cases pass, then OK). ABLATION (decoy repo under mktemp -d, never the real checkout): firing control proven FIRST -- under a leaked GIT_DIR the exact command under test answers for the decoy, `ls-files '*SKILL.md'` = 0 vs 15 real, at exit 0, silently; a second probe confirms the leak survives the pnpm/exec spawn chain. Four legs: L1 (strip, no leak) exit 0, 37 passed; L2 (strip, LEAK) exit 0, 37 passed; L3 (ABLATED, LEAK) exit 1, 1 failed/36 passed; L4 (ABLATED, no leak) exit 0, 37 passed. L3's red is the vacuous-green guard itself: `FAIL src/template-consistency.test.ts > skills catalog boundary > finds the curated skills/ catalog (sanity) / AssertionError: expected 0 to be greater than 0`. L4 is what makes the red mean something -- the red comes from the leak, not the mutation. Mutation landed via scripts/ablation-replace.mjs (anchor 1->0, blob 36ab445bd902->6b125ae11ffb); restore proven on disk (blob == HEAD, `git diff HEAD` empty), not by exit code. ANSWER: yes -- after the conversion the test still fails for exactly the reason it was written to catch. suite: `pnpm --filter create-objectstack test` 16 files / 203 tests all passed. build: green; dependency closure is EMPTY by construction (no workspace deps), so leg 1 is an empty run.

Re-derived after `git fetch origin main` (which advanced to 4b58dcf96b): still 68, zero new families. LINT: repo-wide `pnpm lint` (eslint . --no-inline-config) exit 0 -- run in full, NOT narrowed, so no narrowing evidence is owed. All readings taken at 0e2e1065b0.

Round 1 was blocked by the harness, and round 2 proved what it could only argue

Round 1's Bash tool began refusing every call — including a read-only git status — so ⛔ it could reach GitHub at all. Its findings were posted by the seat as 5750633974. ⛔ It left no edits: clean tree, zero commits, deliberately no unverifiable half-work.

Two things it flagged, both confirmed:

⚠️ the seat's one-file fence could not hold, and the breach was FORCED. Round 2 proved it with a firing gate: on the conversion commit before the declarations existed, check:cross-package-test-inputs exited 1 naming scripts/git-env.mjs; with them it exits 0. ⇒ the claim record 5750582842 has been amended to the three-file surface.
⚠️ the count is TEN, not the card's twelve — and ⭐ that correction strengthened the card: ten is byte-identical to the allowlist fix(scripts): give every throwaway-repo git child an environment of its own (#16644 Tier B) #19168 deleted from both spec carriers, so this was the same shape, not a variant.

⭐ The verification quality worth keeping

typecheck answered as a reading, then proven real. tsc --listFiles places scripts/git-env.d.mts in the program (178/308). ⚠️ But a green can also mean the declaration resolved to any — so it was reverse-verified: dropping the parens turns the same check red with TS2322, then restores to blob == HEAD. ⇒ a green that can be made red on demand is evidence; one that cannot is not.
the ablation's control fires FIRST, and it is the right one: under a leaked GIT_DIR the command under test answers for the decoy — ls-files '*SKILL.md' = 0 vs 15 real — at exit 0, silently. The failure mode is a silent wrong answer, and the control demonstrates exactly that.
four legs, of which ⭐ L4 (ablated, no leak → green) is what makes L3's red mean anything: it proves the red comes from the leak, ⛔ not from the mutation. Without L4 a red only shows that breaking code breaks tests.

⇒ the dispatch's question — after the conversion, does this test still fail for the reason it was written to catch? — is answered yes, by measurement.

Carried, ⛔ not dropped

scripts/git-env.d.mts's header names only the two packages/spec fixtures as its TypeScript consumers; a third now exists, so that sentence is stale. ⛔ Prose, not a gate — check:declaration-mirrors discovers its own corpus and is green. Left alone deliberately; recorded for whoever next reads that header to learn who depends on it.
