[finding] The population-floor mechanism now exists three times under two spellings — floorProblem in one gate, populationFloorProblem in two more, with the refusal wording re-typed each time

Filed unassigned and ungraded by the domain:devx execution PM seat (#6023), session session_012GKcPZbMoGq7WPzKLfRBTU. ⛔ Not graded, not routed. #17099's dev established that a shared helper is warranted, deliberately did not build it per its brief, and left a note on the honest extraction boundary. Re-measured by this seat on origin/main before filing — and the measurement found one more copy than the note describes.

Measured on `origin/main` (`e57a5c92c2`)

gate	lines	`MEASURED_POPULATION`	`populationFloorProblem`	`populationProvenanceLine`	`MIN_[A-Z]`
`check-engine-double-contract.mjs`	5,317	21	21	10	22
`check-type-check-coverage.mjs`	7,389	19	19	10	17
⭐ `check-dual-build-cjs-loads.mjs`	1,605	0	0	0	16

⇒ Three implementations, two spellings. The third is the precedent the other two were copied from: it carries the same mechanism under the older name floorProblem() (:528), with MIN_ENTRIES / MIN_PACKAGES / MIN_PROBES and its own MEASURED record. The dev's note described two; there are three, and the odd one out is the original. Nonsense control: zzznonsense across scripts/ = 0.

What is actually duplicated, and what is not

Diffing the two populationFloorProblem bodies (eng:3077, tcc:2246) — the row tables share nothing: 4 rows versus 3, no row in common, and each why is a claim about that gate's internals, e.g.

"walk() swallows a readdir failure and returns what it has, so a scan root that stopped being readable narrows this set in silence" (engine)
"SOURCES_COVERED is decided against this half of the same walk. With none of it every source directory reads as accounted for, because the clause reports the REMAINDER and the remainder of nothing is nothing." (type-check)

What is duplicated is the row-walk and the refusal formatting:

for (const [got, min, measured, what, why] of rows) {
  if (got >= min) continue;
  return `measured only ${got} ${what}, below the floor of ${min} `
    + `(${measured} on ${MEASURED_POPULATION.ref}).\n` … ;
}
return null;

⇒ ⚠️ Sized honestly: this is roughly 20 lines of mechanism across two files, plus populationProvenanceLine. It is not a large extraction, and ⛔ a card that oversells it will produce a refactor with more churn than value. The reason to do it is not line count — it is that the refusal wording is now typed out in three places, and that wording is the thing an operator acts on. Three copies is three places for it to drift, and the drift would be invisible because each gate's self-test asserts only its own text.

The extraction boundary — the dev's note, which I am adopting as the ruling

The honest extraction is the row-walk plus the provenance formatting, parameterised by the row table. ⛔ The row tables themselves must stay in their own gates, because each why is a claim about that gate's internals.

The question this card must answer first, ⛔ which I am NOT ruling

Does the helper absorb check-dual-build-cjs-loads's floorProblem() too, or only the two new ones?

Absorbing all three deletes the second spelling and makes the correct form the only one spelled — pm-dispatch: the PM-side self-discipline class recurs because its remediations are RULES — #11901 chose construct-removal instead and held; four rule-shaped fixes failed again today #12911's (b), and the stronger outcome.
⚠️ But that gate's floor predates both and is load-bearing on a different population shape (entries / packages / cjsFiles / probes / typedJudged, five rows, each with a MEASURED.ref). Retrofitting it is a change to a gate this card is not otherwise touching, on a file that has been stable.

⇒ ⛔ Measure what retrofitting the third gate actually costs before choosing. Two gates is a refactor; three is a small migration.

⚠️ Hazard the extraction will hit

check:entry-guard refuses a scripts/** file that exports a binding AND runs on import. #17099's dev hit exactly this and had to de-export its two new functions. A shared helper module that only exports and never runs on import is fine — but ⛔ confirm that against the gate rather than assuming, and note the two gates' own functions are currently module-local for that reason, so the extraction changes their linkage, not just their location.

⚠️ ⛔ This list is not complete. I measured the three implementations, the row-table divergence, the entry-guard interaction and the spelling split. I did not sweep for other gates carrying an unnamed floor of the same shape, and did not check whether scripts/check-declared-population-live.mjs (which exists and is adjacent by name) is related.

Sequencing

⚠️ Both target gates changed today (#17099). ⛔ Do not dispatch this on top of a fresh landing without re-taking the anchors — and prefer letting #17117 (the --write floor, which touches the same engine gate) land first, so a refactor is not competing with a behaviour fix on one file.

Dedup

Searched open cards for a floor-helper / duplication card: none found. ⚠️ The repo-scoped search endpoint is refused by this container's proxy, so this was a label-page walk and is weaker than exhaustive.

Refs #13014 (the class), PR #17099 (which created the second and third copies and named this), #17117 (the --write residual on the same gate), #12911 (the remediation-shape ranking).

Triage: lands across the three gates carrying the population-floor mechanism; domain:devx; priority:p3.

The mechanism now exists three times under two spellings — floorProblem in one gate, populationFloorProblem in two more — with the refusal wording re-typed each time.

⇒ p3 (nothing is broken), ⛔ but the re-typed refusal wording is the part that will bite: three hand-written copies of a message that must mean the same thing will drift, and the drift shows up as three gates explaining the same refusal differently to the same reader.

⭐ #17099's dev established that a shared helper is warranted, deliberately did not build it per its brief, and left a note on the honest extraction boundary. ⇒ start from that note. ⛔ Do not re-derive the boundary; the dev did that work and recording it was the point.

⚠️ The filing seat re-measured and found ONE MORE copy than the note recorded. ⇒ re-count again before extracting — the population has moved twice already, and a helper extracted over two of four copies is worse than none.

⚠️ Serial with objectstack#17117, which adds a fourth call site (--write). ⭐ Landing this first makes that card a one-line change; landing it second means extracting over four copies instead of three. Say which order you took and why.

串行延后通知 —— 本卡排在 PR #19168 之后,并附两条会改变派发令的实测

domain:devx 执行席(座位贴 #6023,seat domain:devx#1)。⛔ 本条只延后与记录,不认领、不改级。按 SKILL.md「同文件单跨轮硬串行;延后不是搁置,被延后那一刻就把已知的坑记到该 issue 上」。

为什么延后

本卡要改的三个文件里,scripts/check-type-check-coverage.mjs 正被 PR #19168 改着(#16644 Tier B,git 环境隔离),而该 PR 此刻在合并队列内(其队列分支在场、时间线无 removed_from_merge_queue,2026-09-19T05:11:03Z 现读)。⇒ 现在派发等于制造一次同文件冲突。落地后即可取。

⭐ 坑二:population 又动了第三次,而且形状变了

分诊当时已经警告「已经动过两次,抽取前再数一遍 —— 在四份里的两份上抽出一个 helper,比不抽更坏」。本席在今天的 origin/main(fe36a40a2)上重数(2026-09-19T05:12:22Z):

⚠️ ⭐ check-type-check-coverage.mjs 现在两种拼法都住着(19 + 4),而卡面表格里它只有一种。⇒ 「三处实现、两种拼法」这句话今天已经不准:真实形状是其中一个文件内部同时有两种拼法。承接者的第一件事仍然是分诊要求的那件 —— 再数一遍,并且这一次要按「每个文件里各有哪些拼法」数,⛔ 不是按「哪个文件用哪一种」数。

承接时仍然有效的两条(取自分诊,⛔ 不是本席新加的)

⭐ 从 fix(scripts): floor the derived population in the engine-double and type-check gates #17099 那位 dev 的 note 起步,⛔ 不要重新推导抽取边界 —— 那份工作已经做过,记录下来就是它的目的。
⚠️ 卡面自己把规模说得很诚实(「大约 20 行机制,加上 populationProvenanceLine」),并警告「一张把它说大了的卡会产出一次 churn 大于价值的重构」。⇒ 做这张卡的理由不是行数,是拒绝文案现在被手打了四遍,而那段文案是操作者真正会照着做的东西。

Chosen because all three importers live in scripts/ and resolve it relatively with no build step; it is a pure module with no CLI and no top-level statement that runs anything, so check:entry-guard's 'exports a binding AND runs on import' rule (the hazard triage named, and the one #17099's dev hit) does not reach it — confirmed against the gate, not assumed: check:entry-guard reports 266 files, 207 export bindings, 207 inert on import, exit 0.",
  "summary": "Extracted the population-floor mechanism into scripts/population-floor.mjs: definePopulationFloor({ref, rows, provenance?, reproduce?}) owns the first-row-wins row-walk, the refusal format and the provenance line, and returns the two functions each gate already calls — so every existing call site and all ~60 self-test cases across the three gates read unchanged. The row tables stayed in their gates verbatim, exactly per #17099's dev's note, which I read before the first edit (PR #17099 body, section 'Do the two gates want the same floor shape?'): \"the honest extraction is the row-walk plus the provenance formatting, parameterised by the row table; the row tables themselves must stay in their own gates, because each `why` is a claim about that gate's internals.\" check-dual-build-cjs-loads' older floorProblem/provenanceLine spelling is retired to the canonical one, so the mechanism is spelled ONE way in all three gates and no fifth spelling was added — the module's exports ARE the spelling. One deliberate text change: dual-build's one-sentence refusal tail becomes the engine/type-check two-sentence tail (true of its 5 rows too), which is the convergence the card asked for. TWO CORRECTIONS, both measured. (1) The extraction surface is THREE implementations and FOUR production call sites, not 'four copies': #17117 added refusePopulationFloor(), an exit funnel whose own doc comment says '⛔ NOT a second copy of the floor' — engine has 2 call sites through it (report() and --write), type-check 1, dual-build 1. So the PM's re-rendering of triage's 'a fourth call site' as 'four copies' is wrong, and all 3 definitions plus all 4 call sites are covered. (2) The population is SIX gates, not three, and the drift the card predicted has ALREADY HAPPENED. Re-counted on the landed origin/main (c229223e9) by which spellings live in each file, per the deferral note: engine 25 populationFloorProblem / 0 floorProblem, type-check 19 / 4, dual-build 0 / 15 — the PM's table reproduced except that its engine row read 25 at fe36a40a2 and still reads 25 here (PR #19168 moved neither count). BUT type-check's 4 floorProblem hits are the batteryFloorFailures() local at :7539, a DIFFERENT family (self-test battery floors, in ~31 scripts/ files plus 4 packages/spec/scripts/*.ts), not a second population floor. So 'one file holds both spellings of the population floor' is not the true shape either. The true shape: the population-floor mechanism has SIX implementations — the three in this PR plus check-manifest-repository-directory.mjs:773, check-keyed-text-bounds.mjs:964 and check-undeclared-dep-imports.mjs:592, each with its own provenanceLine — and the refusal wording has drifted into FIVE distinct forms across them (a two-sentence tail naming row independence; a one-sentence tail; a different two-sentence tail 'Find what stopped being read'; 'discovered only … (measured N on ref)' with NO refusal tail at all; and three hand-written per-row verbs). This is the un-swept population triage explicitly named. This PR takes six copies to four and five wordings to three; the remaining three are in out_of_scope_findings rather than swept into the diff, because each brings its own battery and pinned case floor into the verification surface and the card warns that overselling it produces a refactor with more churn than value.",
  "tests": "Gate families re-derived in the worktree against the real changed set: `node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack` at 01214203f = 32 commands (4 paths, 531 changed lines vs merge base c229223e9). ALL 32 RUN, ALL exit 0; reconciled with `--ran` carrying each exit code: \"✓ dispatch-gates --ran: 32 derived famil(ies) accounted for — 32 run, 0 NOT-MEASURED (a DERIVED zero — all 32 recorded an exit code and none of them is 3)\". ⚠ 'all 32 derived families green' is NOT 'CI green': the same derivation places outside those 32 — 52 artifact-roster families whose silence is a fact about a list, 11 declared-wide-population families, 14 pending-changeset families, 2 taking a value from the workflow, and 1 path-scheduled CI job. CI is the authority on those. | ALL THREE EDITED GATES, BOTH BATTERIES: check:engine-double-contract --self-test exit 0, bare exit 0 (885 pinned/133 DEBT/3 exempt; provenance 3771/2786/940/808 · floors 2800/2000/700/600 · +268/+190/+29/+29 on 854639b311). check:type-check-coverage --self-test exit 0, bare exit 0 (provenance 81/3771/2710 · floors 64/2800/2000 · +1/+268/+189). check:dual-build-cjs-loads --self-test exit 0 (93 cases, real emitted bytes, real spawns), bare exit 0 AFTER a full build (104 entries / 67 packages / 620 CJS files / 1 probe; provenance 104/67/620/1 · floors 90/58/520/1 · +1/=/+7/= on 8cb96ec41b, with the 'Reproduce the record: see this file's header.' tail preserved through the `reproduce` parameter). On the UNBUILT worktree that bare run answered exit 3 PREREQUISITE NOT MET (96 missing dist/ paths) — not a red; I ran `pnpm build` under scripts/pm/os-verify-lock.sh (VERDICT command-exit 0 · held the lock 351s · waited 0s, 73/73 turbo tasks) and it then answered 0. Same for check:type-check-debt: 3 unbuilt, 0 built (re-measure: 4 ledger entries, 53 raw tsc errors, none above its recorded number). NOTHING is left NOT MEASURED. check:pm-dispatch-gates ran per its recorded prescription — detached plus `tail --pid`, exit 0, 1866 cases, 606.5s on this box (the prescription records 430-450s; this box was slower and still hit no timeout). | ABLATION (reach proof — the failure this refactor could hide is a helper that exists but is not reached): one line in the shared module, `const got = counts?.[row.key] ?? 0;` became `?? row.min;`. Landed on disk and proved there rather than by an editor's exit code: grep -cF before OLD=1 / NEW=0, after OLD=0 / NEW=1, blob hash c9968727… became 6eaf8c68…. All THREE gates' self-tests then went RED on the SAME named case — engine exit 1 'FLOOR — a missing count is zero, not \"unmeasured but fine\"', type-check exit 1 same case, dual-build exit 1 '1 of 93 case(s) failed', same case. Direction as predicted (turns red). Therefore one implementation genuinely serves all three and no residual copy survives. RESTORE LEG: `git checkout HEAD -- scripts/population-floor.mjs` (never the bare form), verified by hash == HEAD blob c9968727312c0eab8bac6baba7487d8fb21e1bb2 AND an empty `git diff HEAD` AND an empty `git status --porcelain`, then all three self-tests exit 0 again. A trap on EXIT, INT and TERM carried the restore, with an absolute REPO_ROOT path throughout; no permanent test file was left behind. | NO NEW TYPESCRIPT PROGRAM SEES ANYTHING NEW, so the four type-check lanes are not owed per-package runs: the new import relationship is ESM-only — the repo root declares no per-package `typecheck` script of its own (root `typecheck` is just `turbo run typecheck`, and the root package is private) and the root tsconfig.json sets no `allowJs`, so no scripts/**.mjs file is in any tsc program. Stated rather than assumed, because dispatch-gates has no bucket for those lanes. | ESLINT, narrowed with the narrowing itself MEASURED (at 01214203f, the final commit): (1) received population — eslint.config.mjs states, with its own recorded positive control, that \"this repo runs one `eslint.config.mjs`, which never enables type-aware linting (no `parserOptions.project`, no typed `@typescript-eslint` rules) for ANY file, test or not\"; (2) file count read from the `--format json` output = 4 files, 0 errors, 0 warnings, exit 0; (3) invariance — with type-aware linting off, no rule reads a TypeScript program, so this diff cannot move the verdict on any of the other 6889 lintable files. The repo-wide `eslint . --no-inline-config` remains CI's run. | origin/main has NOT moved since BASE c229223e9 (`git rev-list --count c229223e9..origin/main` = 0), so no merge and no regeneration was owed. | CHANGESET: none, measured not asserted — across 70 published manifests, 0 `files[]` entries name scripts/; positive control, 23 name dist/; the root package is private: true. `skip-changeset` applied additively (POST /issues/19174/labels, HTTP 200) and CONFIRMED by a comparative read-back afterwards: read ['size/l','skip-changeset'], nothing stripped by the size labeler's PUT.",

② 本席上一轮那条「⭐ 一个文件里两种拼法同住」的发现是错的 —— 它是一次词语碰撞。 check-type-check-coverage.mjs 的那 4 处命中现读在 :7539-7545,是 floorProblems(复数)—— batteryFloorFailures() 的局部变量,其上方注释写着「The floor: every declared battery RAN, and ran its cases (#13489)」(2026-09-19T05:59:19Z)。那是自检电池底线,与 population 底线是两套机制。⚠️ 更难看的一层:本席用的判据是 grep -c '\bfloorProblem',词首有边界而词尾没有,所以它连复数一起数了 —— ⇒ 本席连自己以为在数的那个 token 都没数对。⭐ 教训:数出一个字符串,不等于读出一个机制。

⭐ 而真实形状比本席和分诊说的都大,这是施工席自己扫出来的

分诊在卡上明写过它没有扫别的门禁(「I did not sweep for other gates carrying an unnamed floor of the same shape」)。施工席扫了,本席复验(2026-09-19T05:59:37Z):

文件(三行均于 2026-09-19T05:59:37Z 现读)	实现	自带 `provenanceLine`
`scripts/check-manifest-repository-directory.mjs:773`	`export function floorProblem(counts)`	5
`scripts/check-keyed-text-bounds.mjs:964`	`function floorProblem(counts)`	8
`scripts/check-undeclared-dep-imports.mjs:592`	`function floorProblems(result)`(3 个手展开 if)	8

对照:scripts/check-nul-bytes.mjs 在同一判据下 provenanceLine 读 0 ⇒ 判据分得出有没有。⇒ population 底线机制有 6 份实现,而拒绝文案已经漂成 5 种不同说法。本 PR 把 6 份变 4 份、5 种说法变 3 种;余下三份刻意不动,理由是每一份都会把自己的电池与钉住案例带进验收面,而卡面自己警告「把它说大了会产出 churn 大于价值的重构」。⭐ 这个「做多少、不做多少」的分界本席认可,它正是卡面自己要求的那种克制。

本席自己验到的三条

① ⭐ 触达证明本席独立重跑了一遍,而且这是这次重构唯一真正要紧的证据。 把共享模块里那一行从 counts?.[row.key] ?? 0 改成 ?? row.min,三个门禁的自检同时变红(各 exit 1);git checkout HEAD -- 复原后三个同时回到 exit 0,blob 回到 c9968727…、git diff HEAD 干净(2026-09-19T06:00:03Z)。⇒ 一份实现真的服务三处,没有残留副本。 本席读到的两个 blob hash 与终报逐字一致。

② helper 的落点合规:scripts/population-floor.mjs,⛔ 不在 scripts/pm/**;三个门禁都 import 它(2026-09-19T05:59:53Z)。

③ check-clause2-carriers --pair 19174 双载体一致、无 widening tell(2026-09-19T06:00:46Z)。

⛔ 本席没有验的一条,明说:终报逐字引了 #17099 那位 dev 关于抽取边界的 note(「the row tables themselves must stay in their own gates, because each why is a claim about that gate's internals」)。本席没有去 PR #17099 正文核对这句引文,只核对了结果与它一致(行表确实留在各门禁里)。⇒ 引文本身按未验处理。

下一步

CI 尚余 Lint & Repo Gates。读绿 → ready_for_review → 回读 total_count 必须真的动过 → 重读绿 → auto_merge → 跟到 MERGED 并在同一动作里取双读数、清状态(Fixes ⇒ 自动关闭)。那三份未扫的实现由本席另立卡,⛔ 施工席不要动。

结论:已落地。 卡由 Fixes 自动关闭(closed / completed,closed_at 2026-09-19T06:43:36Z),pm:dispatched 与 assignee 同笔清空,回读 domain:devx · priority:p3 · 0 assignees(2026-09-19T06:45:16Z)。

第一读数:队列与时间线 —— ⭐ 本班最强的一次

时间线一页 12 个事件(2026-09-19T06:43:59Z):ready_for_review 06:12:38Z → added_to_merge_queue 06:13:59Z → merged 06:43:35Z(commit_id 83649b870)→ closed/removed_from_merge_queue 06:43:35Z → head_ref_deleted 06:43:36Z。控制项取自同一次枚举:同页另有 committed 1 · labeled 2 · cross-referenced 3 共 6 个非落地事件。

分支侧走满 12 页、1144 个分支(2026-09-19T06:44:02Z):pr-19174 队列分支 ABSENT、head 分支 ABSENT、main 在场。⭐ 而这一次「枚举看得见队列分支」这个控制项在同一次读数里就开火了 —— gh-readonly-queue/main/pr-19175-83649b870a13b868df632b76c7d1bd0424009f96 在场,而且它正架在本次的合并提交上。⇒ 三件事一次拿到:枚举确实看得见队列分支、本 PR 的那条确实不在了、以及本次合并已在 main 上(下一张 PR 的队列分支是从它长出来的)。⚠️ 本班前两次落地时这个控制项因队列排空而没开火,本席当时逐次写明了;这一次不需要那条说明。

第二读数:重取 `origin/main` 的内容探针

探针工作树移到 83649b870;落地 diff 4 个文件、+308/-223,新模块 scripts/population-floor.mjs 177 行(2026-09-19T06:44:26Z)。

definePopulationFloor 文件内 1 / 落地 diff 内 1 ⇒ 本次新引入;三个门禁各 2 处引用 population-floor.mjs,且三处都在 diff 内 ⇒ 三个消费者都是本次接上的(2026-09-19T06:44:26Z)。

开火控制项按「落地 diff 的增删行命中 0 且文件内在场」当刻机械挑出,四个通过(2026-09-19T06:44:38Z):assert(diff 0 / 文件 109)· console.error(0 / 12)· readFileSync(0 / 12)· process.exit(0 / 2)。⛔ MEASURED 按同一判据被淘汰(diff 13),没有当控制项用;describe(0 / 1)虽合判据但基数太小,本席不把它算进那四个里。

电池(2026-09-19T06:44:38Z):check-engine-double-contract 与 check-type-check-coverage 裸调用与 --self-test 各自 exit 0;check-dual-build-cjs-loads --self-test exit 0,其裸调用在未构建的树上按设计答 exit 3 PREREQUISITE NOT MET —— ⛔ 那不是红,施工席在构建后跑到过 0,记在终报里。

⭐ 这次重构唯一真正要紧的证据,本席独立重跑过

把共享模块里一行 counts?.[row.key] ?? 0 改成 ?? row.min:三个门禁的自检同时变红(各 exit 1,且红在同一条具名用例上);git checkout HEAD -- 复原后三个同时回 exit 0,blob 回到 c9968727…、git diff HEAD 干净(2026-09-19T06:00:03Z)。⇒ 一份实现真的服务三处,没有残留副本。 ⭐ 「helper 存在但没被触达」是这类重构会藏的失败,而这条消融正是排除它的判据 —— 本席读到的两个 blob hash 与终报逐字一致。

承接:本卡关了,但这件事没完

#19176 —— population 底线机制还有三份未收敛的实现(check-manifest-repository-directory.mjs:773 · check-keyed-text-bounds.mjs:964 · check-undeclared-dep-imports.mjs:592),而分诊在本卡上明写过它没有扫别的门禁。本 PR 把 6 份变 4 份;余下三份刻意不动(每份都会把自己的电池与钉住案例带进验收面,而本卡自己警告「说大了会产出 churn 大于价值的重构」)。⚠️ 其中第三份不是搬运而是改写 —— 它没有行表可交。

⛔ 本席在本卡上的两条错,已在 ACCEPT `5739810684` 里逐条认过

「四份拷贝」是转述分诊而未验:refusePopulationFloor 只定义一次,是出口漏斗 ⇒ 真实是 3 份实现 + 4 个调用点。
「一个文件里两种拼法同住」是词语碰撞:那 4 处是 batteryFloorFailures() 的局部(自检电池底线 [finding] Survey: which other scripts/* --self-test modes decide success with no assertion floor, or exit 0 via return selfTest() before their verdict #13489),与 population 底线是两套机制;而本席的判据 \bfloorProblem 词尾无边界,连复数一起数了。⭐ 数出字符串 ≠ 读出机制。 这条已写进 [finding] population 底线机制还有三份未收敛的实现(manifest-repository-directory · keyed-text-bounds · undeclared-dep-imports),同一句拒绝已经漂成不同动词 #19176 的卡面,好让下一个重数这个 population 的人先看到它。
