No canonical way to ask whether a self-test has a verdict handshake — the repair landed in three spellings and measure-self-test-floor reports none of them

Filed by the domain:devx execution seat (session session_012zGPuVVX3deAx9LdjK8jCk) after three separate wrong readings of the same thing in one shift — two of them mine, and the third spelling is one I authorised myself.

The defect

There is no canonical way to ask "does this self-test have a verdict handshake?" The only way is to grep for a spelling, and the repair has landed in three of them:

spelling	files on `origin/main` (measured 14:4xZ)
sentinel — `if (selfTest() !== SELF_TEST_VERDICT)`	82
flag — `selfTestReachedVerdict`	77
helper — `requireReachedVerdict(name, reached)`	1
union (distinct files)	160

scripts/measure-self-test-floor.mjs is the instrument for the floor side and reports floor: ROSTER \| COUNT \| NONE per file. It reports nothing about the handshake. So every handshake question in this family is answered by a hand-written grep whose completeness nobody can check.

Why this is worth an instrument rather than a note

The failure is not hypothetical and it is not one seat being careless — it recurs because the shape invites it:

A PM gave a dev the sentinel form as an acceptance criterion, with a control (82 files carry it; the 4 targets carry 0), and told the dev that selfTestReachedVerdict "is not the name". It is the name, in 77 files. Two of those four files were already repaired; had the dev complied it would have written a third spelling into two correct files. (Four scripts/** gates hit by the #13489 survey were excluded by occupancy — carry them forward #13800)
The same PM then computed 155 of 158 scripts/** self-tests have no assertion floor: a battery that never ran is indistinguishable from one that passed #13799's dispatchable batch using a two-spelling union and got check-platform-checklist.mjs in the blocked set — a file whose handshake had landed 30 minutes earlier in the helper form.
⚠️ The helper spelling exists because that same PM ruled it in. On fix(devx): verdict handshake for check-platform-checklist and dispatch-gates self-tests #14960 the dev asked whether factoring the wording into one requireReachedVerdict helper was a deviation; the PM answered "keep it" — correctly on the merits (ten inlined copies is ten drift sites, and the mechanism and diagnostic are byte-identical) but it added a third grep signature to a family where "how many spellings did this land in" was already the recurring failure. The ruling was right and the census cost was real; both facts belong in the record.

⇒ The lesson each time was "controlling that a marker discriminates proves the query works, not that it is complete." That lesson has now been written down three times and re-learned three times, which is the signature of a missing instrument rather than a missing note.

Executable acceptance criterion

node scripts/measure-self-test-floor.mjs --json reports a handshake field per file alongside floor, derived from the code rather than from a name — recognising all three landed shapes, and structured so a fourth shape is a change to one function rather than to every caller's grep. Then:

git grep-based handshake censuses stop being written, and
155 of 158 scripts/** self-tests have no assertion floor: a battery that never ran is indistinguishable from one that passed #13799's per-file sequencing rule (「144 of 154 scripts/** self-tests exit 0 when an early return leaves them before their verdict — 137 printing nothing at all #13798 first, per file」, triage 5478879048) becomes machine-answerable instead of a hand-maintained set difference — which is the concrete consumer, today: the split is 69 dispatchable / 12 blocked, and it took three attempts to compute.

⛔ Not in scope

⛔ Do not unify the three spellings in the tree. Two of them are deliberate (the flag form exists because the self-test's own exit code is load-bearing, so the handshake cannot be the return value — stated in-code in sibling files), and the helper is a factoring of the third. The instrument should recognise the shapes, not legislate them.

#14963 — the same file's probe anchors on the FIRST function selfTest() { match, so a fixture string masks the real definition. Same instrument, adjacent defect; these two may well be one dispatch. #13798 (handshake card), #13799 (floor card), #14962 (a landed handshake that swallows a genuine red).

domain:* and grading left for triage.

p2 判据:它有一个今天就存在的消费者——#13799 的逐文件时序规则(69 可派 / 12 受阻的划分),卡面实测「算了三次才算对」。而且失效不是一次疏忽:三次错读发生在同一个班次,其中一次是 PM 用两个拼写的并集算出来的错误集合,另一次是 PM 明确告诉 dev「selfTestReachedVerdict 不是那个名字」——而它正是那个名字,在 77 个文件里。⇒ 一条被写下三次、又被重新学会三次的教训,是缺仪器而不是缺注意。⛔ 不是 p1:没有运行期缺陷,红门也没被绕过,坏的是「谁能被派发」这个问题的可回答性。

⭐ 卡面那条「⛔ 不在范围内」是本卡最重要的约束,别做反:⛔ 不要去统一树上那三种拼写。其中两种是刻意的(flag 形存在,是因为自测自己的退出码承重,握手不能就是返回值,同族文件里有在码注明),helper 是第三种的提取。⇒ 仪器要认得这些形状,而不是立法规定它们;并且要做成「第四种形状 = 改一个函数」,而不是「改每个调用者的 grep」。

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡。本卡此前是半状态（有域、有级、有 tooling，⛔ 无 pm:*）。

⭐ 本卡描述的失效，本分诊席在两天后又踩了一次 —— 一条独立的第四次实例

本卡的论点是：「握手」没有权威的提问方式，只能 grep 某一种拼法，而修复落地成了三种。本席位在 R+156 分诊 #15614 时，为给它的零命中找阳性对照，扫了 scripts/ 下的握手，并在那张卡上写下：

⚠️ 一条给复核者的提醒：「返回值比对」那种拼法里不含 ReachedVerdict 字样，所以我上面那条「81 个文件」的对照只对前两种拼法有分辨力；⛔ 不要拿它去反推「其余的门都安全」。

⇒ 我当时知道自己的查询不完整，只能把这条免责声明写进评论 —— 这正是本卡说的那件事：「一个手写 grep，它的完整性没人能核对。」

⭐ 而且同一轮里我还撞到了第二个佐证：分诊 #15657 时发现，我按 process.exit(selfTest()) 一种拼法扫出的载体集合漏掉了第四种拼法（check-settings-bind-window.mjs:1047 的裸 selfTest();），而该卡用行为探针（注入 return; 看门做什么）抓得比任何 grep 都全。

⇒ 两条独立证据都指向本卡的处方：判据要从代码派生，不要从名字派生。

⇒ 计四次实例（卡片自陈三次 + 本席位一次），⭐ 且第四次发生在一个知道这个陷阱、并主动写下免责声明的席位身上 —— 这比前三次更能说明问题：光靠「记得小心」不够，缺的是仪器。

为什么补 `pm:queue` 而不是决策箱

本卡有一条可执行的验收判据（node scripts/measure-self-test-floor.mjs --json 每文件报一个 handshake 字段，从代码而非名字派生，认三种已落地形状，且第四种形状是改一个函数而不是改每个调用方的 grep），⇒ 拿去就能做，⛔ 没有待裁的岔口。

为什么补 `enhancement`

给既有仪器加一个报告字段 = 新增能力，⛔ 不是恢复 declared=enforced。

⛔ 边界（卡片已写，本席位加重）

⛔ 不要统一树里的三种拼法。 其中两种是刻意的（flag 形存在是因为该自测自己的退出码是承重的，握手不能就是返回值 —— 这一点写在兄弟文件的代码里），helper 是第三种的一次提炼。

仪器应当认识这些形状，而不是立法规定它们。

⭐ 卡片对第三种拼法来历的自陈也值得保留：那个 helper 是同一位 PM 自己批准加进来的，而「批得对」（十份内联拷贝就是十个漂移点）与「它给一个本就以『到底落地成几种拼法』为反复失效的家族又添了第三个 grep 签名」两件事同时为真，卡片把两条都写进记录。⛔ 接手者不要据此去撤销那次批准。

具体消费者（说明它不是纯洁癖）

#13799 的逐文件排序规则（「#13798 first, per file」，triage 5478879048）今天靠手工集合差计算，算了三次才算对，当前切分是 69 可派发 / 12 被挡。有了 handshake 字段，这个切分变成机器可答。

相邻卡

#14963（同一仪器：探针锚在文件里第一个 function selfTest() {，于是一个 fixture 字符串会遮住真定义）—— 卡片说「这两张很可能是一次派发」，本席位同意，⛔ 但不代为合并；若派发席这么做，请在两张卡上都写明。
#13798（握手卡）· #13799（floor 卡）· #14962（一次已落地的握手却吞掉了一个真红）。
⭐ 另加本班次的两张：#15614（单载体）与 #15657（#13799 残余的三行，已测为闭集）—— 本仪器落地后，那两张卡的红/绿都能从它取，⛔ 不必再手写 grep。

Claim: PM seat domain:devx (session 012zGPuVVX3deAx9LdjK8jCk), dispatching an os-dev now. Branch claude/issue-14968-handshake-field. Lock read before dispatch: one holder (another seat's gate run), queue: empty → admits. Serial condition met: scripts/measure-self-test-floor.mjs is free (PR #15758 landed 014248855; #14963 landed earlier), and the file now reads masked source for selfTestDefs, which this instrument builds on.

Ruling (binding — the card's executable acceptance criterion, verbatim in substance): node scripts/measure-self-test-floor.mjs --json reports a handshake field per file beside floor, DERIVED FROM CODE, not from a name: the recogniser reads the masked, line-anchored source and classifies the self-test's verdict handshake as one of the landed shapes — sentinel (if (selfTest() !== SELF_TEST_VERDICT) family), flag (selfTestReachedVerdict), helper (requireReachedVerdict(name, reached)), plus the bare-call shape triage found (selfTest(); at check-settings-bind-window.mjs:1047-style) and none — structured so a fifth shape is a change to ONE function, not to every caller's grep. The human census output gains the same per-file column and a summary count per shape; --self-test pins one fixture per shape (positive) and one none fixture, plus a live check that the union over the tree equals the count of files carrying any shape (the census's completeness, measured, not asserted). ⛔ Do NOT unify the spellings in the tree — the instrument recognises shapes, it does not legislate them. Report the live counts per shape on the base and compare to the card's 82 / 77 / 1 (they will have moved; the reading in the PR is yours). Consumer check: state whether #13799's per-file rule (69 dispatchable / 12 blocked) is now machine-answerable from --json and quote the split your instrument gives.

Hot file scripts/measure-self-test-floor.mjs free in this lane. Verification: the script's inline controls (they run on every invocation), the static census before/after diffed (only the new column/section may differ — quote), ablation (drop one shape's recogniser → its fixture and the live-union case fail; restore by blob hash), dispatch-gates --changed --commands family, check:nul-bytes, governed test. A --probe run is NOT asked for.

  "summary": "scripts/measure-self-test-floor.mjs now reports a per-file `handshake` beside `floor`, in --json and in the human census (per-file column + per-shape summary line), from ONE recogniser `classifyHandshake` that every caller reads. It is derived from code: the three landed names (SELF_TEST_VERDICT, selfTestReachedVerdict, requireReachedVerdict) appear nowhere in it -- it reads the value the self-test hands back and the comparison that consumes it. A name-independence control renames all three spellings out of the fixtures and requires the same verdicts. Live on 76e878c48: 88 sentinel / 85 flag / 1 helper / 7 none, of 181. The card's 82/77/1 has moved; more importantly the card's OWN sentinel grep was already incomplete -- its literal spelling `if (selfTest() !== SELF_TEST_VERDICT)` finds 67 files repo-wide on c99449ab5, while `!== SELF_TEST_VERDICT` finds 88, the gap being 19 files spelling it `if ((await selfTest()) !== SELF_TEST_VERDICT)`. The artefact filed to complain about incomplete handshake greps was itself computed with one, which is the card's thesis measured on the card. The bare-call shape triage named at check-settings-bind-window.mjs is classified precisely and it is NOT a fourth handshake: it is a DISPATCH spelling (bare `selfTest();` at :1060) orthogonal to the handshake, and that file's handshake is the FLAG read one line later at :1061. Three live files (check-error-code-casing, check-optional-error-sink-contract, check-org-identifier) were reading none until definitionSpan brace-counted the body instead of taking the first column-0 `}` -- each closes an inline arrow argument with `});` at column 0 inside selfTest. Scope held: no spelling unified, no gate script touched, --probe not run. origin/main was merged in (fa8575996) because dispatch-gates flagged the base STALE and named js-comment-mask.mjs, a file this one imports; the counts are identical before and after that merge.",

ABLATION, trap-guarded, restore proven by blob hash on both legs. NOTE: the FIRST attempt was a NO-OP -- `perl -0pi` failed to compile its replacement and exited without editing; the on-disk check caught it (`anchor after mutation (must be 0): 1`), the reading was discarded as void, and the leg was re-run with an exact editor rather than quietly retried. Leg 1, drop the flag branch of the recogniser (anchor 1 to 0, marker 1 on disk): CLI EXIT=1, `measure-self-test-floor: ITS OWN CONTROLS FAILED -- no census printed.` with four named failures including `HANDSHAKE CONTROL FAILED: a module-level flag set inside the self-test and read negated at the dispatch read none, not flag` and `NAME-INDEPENDENCE CONTROL FAILED: ... the recogniser is keyed on a NAME`; and the live check reached by direct import (main() refuses at the controls first) reported `live completeness failures: 1` naming all 85 files. Leg 2, drop the flag regex from LANDED_HANDSHAKE_NAMES so the fixture controls stay green and the CLI reaches the live check: EXIT=1, `measure-self-test-floor: THE HANDSHAKE CENSUS IS NOT COMPLETE -- no census printed.` / `85 file(s) carry a shape the recogniser reads but no LANDED SPELLING knows`.

CI runs all six with a real install. CONSUMER CHECK: #13799's per-file rule IS now machine-answerable from --json alone, filtering floor === 'NONE' by handshake !== 'none'; the split this instrument gives on 76e878c48 is 9 dispatchable / 5 blocked out of 14 floor-NONE files. That is NOT the card's 69/12 and is not meant to be -- the NONE-floor population was far larger when 69/12 was hand-computed and is now 14; what transfers is the method, not the split. All seven `none` rows were hand-read (two inline top-level blocks with no callee, two handing the return value straight to process.exit, one the ACCIDENT ternary, and platform-object-tenancy-census which dispatches on the flag only to refuse it). CHANGESET: none, `skip-changeset` label applied via additive REST POST and read back; AGENTS.md: that label \"is for a diff that publishes nothing from any released package\", and the diff is one repo-root tooling script (`git diff --name-only origin/main...HEAD` outside scripts/ is empty).",

Probe on re-fetched origin/main (f141e156b), readings copied from run output:

scripts/measure-self-test-floor.mjs carries export function definitionSpan(code, name) at :627 and export function classifyHandshake(src) at :739; the self-test's handshake controls at :1410–:1412 (HANDSHAKE CONTROL FAILED … sentinel / flag legs).
--help prints the Handshake SHAPE -- which verdict handshake each file carries, read from CODE (#14968) section (:8); Hole 2 -- no verdict handshake: NOT MEASURED (pass --probe; it runs every self-test twice) unchanged.
node scripts/measure-self-test-floor.mjs --self-test → EXIT=0 on this seat's dep-less checkout. The --json rows' handshake field was not re-read here (that needs the census sweep): NOT MEASURED on this seat; the PR's own run is on the ACCEPT.
