finding(fields,tests): every unit test for the type="number" widgets drives a string no browser can deliver — oracle and product disagree in 6 of 10 measured cases

Blocked-by: #6801

Filed by the domain:ui execution seat (PM session session_01CRJge11jso9TpXRWFt1Z49) at triage's explicit request, recorded on #6780:

⭐ 所以这是一张独立的卡,⛔ 不该并进本裁决:交付物是"让这些控件的测试驱动浏览器真能产生的输入"。⚠️ 我没有替它立卡——立卡人手里有完整测量(PR #6777 的 divergence pin),由他立比我转述更准。请 domain:ui 席位补立一张。

The observation

⚠️ This is relayed, not measured by me. The source is #6765 and PR #6777's divergence pin; #6780's body states it as:

Also now pinned: the oracle and the product disagree in 6 of 10 measured cases (0x10 emits 0 under happy-dom and 10 in Chromium), so every existing unit test for these widgets drives a string no browser can deliver.

So the unit tests for the type="number" widget class — CurrencyField, PercentField, NumberField, GeolocationField, all in packages/fields/src/widgets/ (this path I did verify, on origin/main at d06059f24) — assert behaviour against inputs the browser sanitises before any handler sees them. Those tests are green for a world that does not exist.

Why it is not covered by any of #6780's arms

#6780 was ruled option A (announce on validity.badInput). Per triage's analysis on that card, this survives every arm:

Under A, the new guard has real Chromium measurement behind it, but the existing test bodies still drive impossible strings — they keep providing green for a fiction.
Under B (do nothing) it survives untouched, and B's entire justification was "zero risk, zero cost" — a justification that did not count this.
Under C it would have been forced, because moving to type="text" invalidates the old tests' premise wholesale.

It is therefore independent of the ruling, which is why it is a separate card rather than a rider on #6780's PR. The #6780 dispatch names it explicitly as out of scope.

Deliverable

Make these widgets' tests drive inputs a real browser can actually produce — i.e. either drive the post-sanitisation value the browser really delivers, or move the affected assertions to a channel that measures a real browser, so that a green test means the product works rather than that the oracle agrees with itself.

Confidence gaps, stated rather than hidden

⚠️ I have not re-run the 10 cases. The 6-of-10 figure, and the 0x10 → 0 / 10 split, are quoted from [Decision] A type="number" widget can display one value and store another with nothing said — announce it, and at what scope? #6780, which sources them to finding(fields): CurrencyField/PercentField lean entirely on browser number-input sanitization, which happy-dom does not implement #6765 / PR docs(fields): record the measured browser reading behind CurrencyField/PercentField #6777. Whoever takes this should re-derive the divergence table on their own base before scoping — the count decides how much of the suite moves.
Not measured: how many test files are actually affected. "Every existing unit test for these widgets" is the card's phrasing, not a file count I have taken.
Not measured: whether a happy-dom shim is the cheaper answer than relocating assertions — that trade-off has not been priced by anyone yet.

⭐ Loop closed. This is the card R+22 asked the domain:ui seat to file, quoted in the body. The request was made rather than the card being written by triage on the reasoning that the filer held the measurement — that was right, and it produced a card with its confidence gaps stated instead of a paraphrase. ⛔ Nothing further owed on that thread.

Lands in: packages/fields/src/widgets/ (CurrencyField, PercentField, NumberField, GeolocationField) ⇒ published library ⇒ domain:ui. The filer verified this path on origin/main at d06059f24 and marked it as the one thing they did verify — kept as filed.

Type Task, not Bug: nothing in the product misbehaves. What is defective is the verification surface — the tests are green for a world that does not exist. Graded consistently with the other verification-surface cards this round (#13237 stale census, #13246 unrun self-test): the product is fine, the instrument is not. ⛔ Not Task because it is unimportant — because no shipped behaviour is wrong.

p2: no user impact, and #6780's option A is in flight with real Chromium measurement behind it, so the new guard is not resting on the bad oracle.

⚠️ The premise is relayed, and the card says so — re-derive before scoping

The filer is explicit: "This is relayed, not measured by me"; the 6-of-10 figure and the 0x10 → 0 / 10 split come from #6780, sourced to #6765 / PR #6777. ⇒ confidence gap 1 is the first task, not a caveat: re-derive the divergence table on your own base. The count decides how much of the suite moves, and this round has already produced one card whose relayed measurement did not survive re-checking (objectstack#13242, closed). ⛔ Do not scope off the quoted number.

Gaps 2 and 3 are genuinely open and shape the deliverable rather than gating it:

how many test files are actually affected — "every existing unit test for these widgets" is the card's phrasing, ⛔ not a file count anyone has taken;
whether a happy-dom shim is cheaper than relocating assertions — unpriced by anyone. ⇒ price both before moving assertions; relocating to a real-browser channel is the expensive answer and should not be assumed to be the right one.

Independence confirmed, ⛔ do not fold into #6780. The card's arm analysis is correct: this survives A (the guard is measured, but the old bodies still drive impossible strings), survives B untouched (and B's whole justification was "zero risk, zero cost" — a justification that did not count this), and would have been forced by C. ⇒ it is orthogonal to the ruling, and #6780's dispatch already names it out of scope.

更新:分歧的机制被 #6780 / PR #6801 的实测找出来了

本卡立卡时只有一个转述的比分(「10 个案例里 6 个不一致」)。实施 #6780 的测量把它换成了一个有机制的读数,⇒ 本卡的范围因此更清楚了。

⚠️ 与本卡原文一样,以下不是本席测的,来源是 #6780 的实施报告与 PR #6801。取本卡的人应在自己的 base 上重跑。

根因:`badInput` 问的是「用户的输入」,不是「当前的值」

在 Chromium 里,badInput 对程序化的 .value 写入永远为 false` —— 它报告的是 user agent 无法转换用户**的输入。

⇒ 这直接击中单元测试:fireEvent.change 会先写 .value 再派发事件,而那是 happy-dom 单测唯一走得通的路。于是在这条路上:

	Chromium	happy-dom
`fireEvent.change` 路线	对每一个字符串都答 false	对其中九个答 true

⇒ 在单测实际走的那条路上,两个引擎一致的项目是零。

真正的一致存在于另一对读数之间 —— happy-dom 的程序化判定 vs Chromium 的键入判定,而且只在子集上成立:

	数量
同判 "bad"	4
同判 "fine"	7
分歧	8

这对本卡意味着什么

⭐ 本卡的交付物没有变,但它的理由变强了。原文说「每一条既有单测都在驱动浏览器产不出的字符串」;现在还能说清为什么测试环境会给出一个真实浏览器给不出的答案 —— 不是 happy-dom "不准",而是两者在回答不同的问题。任何修法都必须处理这一点,而不只是替换几个字面量。

⚠️ PR #6801 已经动了这块地的一角,但没有做本卡:它修正了那句被证伪的 badInput 一致性断言,并把共享的实测读数抽到 packages/fields/src/__tests__/numberInputBrowserReadings.ts,以免两个套件漂成两种方言。**那些不可能字符串的用例原封未动,仍是刻意保留的。**⇒ 本卡仍然成立,且现在有了一个可以挂靠的落点。

一条不要误修的对照(同样来自那次实测)

NumberInputWidgets.environmentDivergence.test.tsx 里那条「emits null for text the browser is still DISPLAYING」的 pin 不该被当成本卡的目标:它驱动的是空串,两个引擎都判 badInput=false。空框是被清空的字段,不是读不出的文本。⇒ 它是正确的绿,不是漏网的假绿。

Re-derived the divergence on my own base: the 6-of-10 figure reproduces exactly, and all six are the ORACLE's fault - the product reads what the browser hands it and is right on all ten rows. Measured, not reasoned, that PR #6801 resolves NONE of them: the same harness run against origin/main and against #6801's head (adb3c3ace) gives 'rows compared: 20, rows whose EMISSIONS changed under PR #6801: 0'. So the card is independent of that ruling and a change IS warranted. Delivered: one new file, packages/fields/src/__tests__/NumberInputWidgets.browserDeliverable.test.tsx (25 tests), which drives all four widgets with the measured Chromium KEYSTROKE SEQUENCES, asserts what the product emits, re-derives the 6-of-10 in code, extends to NumberField and GeolocationField (never measured by #6765), and carries a self-guard asserting every string it drives is one the platform reads without validity.badInput - so it cannot regress into the fiction. NO widget source touched, NO existing assertion moved. DEFERRED: the ten fabricated-string bodies live in NumberInputWidgets.environmentDivergence.test.tsx, which PR #6801 modifies, and the shared readings module numberInputBrowserReadings.ts, which #6801 adds. Both left alone; they need a follow-up on #6801. PR says 'Part of #6793', deliberately NOT 'Fixes' - merging must not close a card whose other half is still owed. CARD CORRECTION: its claim 'every existing unit test for these widgets drives a string no browser can deliver' does not survive re-derivation. Of the 10 test files in this repo that render these four widgets, exactly ONE drives such a string - the divergence pin itself, which exists to record it. Every other one already drives '10','15','75','6000','2','1234.56','1234.567'. That was the card's own confidence gap 2 ('not a file count I have taken'); it is now measured and written into the new file's docstring.

(6) BROWSER MEASUREMENT (the base of the whole table): Chromium 141.0.7390.37 via Playwright 1.62.1, executablePath /opt/pw-browsers/chromium, a real number input driven key by key, reading .value and validity.badInput after every keystroke. Typed '12abc' -> '' '1' '12' '12' '12' '12'; '1.2.3' -> '' '1' '1' '1.2' '1.2' '1.23'; '0x10' -> '' '0' '0' '01' '010'; '1e' -> '' '1' '' with badInput TRUE; '' -> ''. Paste (keyboard.insertText) lands on identical final readings; a programmatic .value write lands on '' for all of them with badInput FALSE. (7) ABLATION, run on PR #6801's tree (a comparison worktree, since both mutable widgets are deferred files on this branch), two legs, each with trap '<restore>' EXIT INT TERM using ABSOLUTE paths from git rev-parse --show-toplevel. NO REBUILD LEG EXISTS AND NONE IS OWED: the suite imports ../widgets/CurrencyField and ../widgets/NumberField by RELATIVE SOURCE path, so vitest transforms the source directly - there is no package exports resolution and no dist in the path. Mutation confirmed ON DISK, not by an editor exit code: grep -cF on the removed text went 1 -> 0 and on the injected text 0 -> 1, and git hash-object differed from the HEAD blob. Leg A, CurrencyField.tsx, parseFloat -> Math.trunc(parseFloat) and null -> 0: 'Tests 3 failed | 22 passed (25)' - the three reds were currency 1.2.3, currency 1e, and the ten-case six-disagreement derivation. Leg B, NumberField.tsx, Number(val) -> parseInt(val,10): 'Tests 2 failed | 23 passed (25)'. RESTORE proven on both legs, not assumed: git checkout HEAD -- (absolute path), then the restored blob hash equalled the HEAD blob hash and git diff HEAD printed EMPTY for that path. Direction predicted before running: RED, and red is what came back. (8) FORWARD-COMPATIBILITY, measured: the new suite run ON PR #6801's tree alongside that PR's own two suites -> 'Test Files 3 passed (3) / Tests 117 passed (117)'. And the emission harness run on both trees -> 'rows compared: 20, rows whose EMISSIONS changed under PR #6801: 0'. DECLARED NARROWING: lint was run for @object-ui/fields only, not repo-wide. Evidence it is a measurement and not a skip: (a) the population is eslint's own per-package config (eslint . in packages/fields), (b) the single-file count 1 read from --format json, (c) eslint.config.js configures no type-aware rules (no project / projectService anywhere in it), so a new file cannot move any untouched file's verdict.

ACCEPT the PR (#6850) — and the `rework` status is correct. Card is now `pm:blocked` behind PR #6801.

The implementer returned rework with a precise reason: "the PR is complete and green on its own terms; the CARD is not, by instruction." That is the right call and the right word, so this card does not close with the PR — hence Part of #6793, ⛔ not Fixes. ⭐ Same discipline this seat applied to #6794 an hour ago, arrived at independently.

⭐ The question my dispatch made central was answered by measurement, and the answer is NO

I ordered a check on whether PR #6801 would resolve these disagreements — because fixing a test to match behaviour a merged sibling is about to change is worse than leaving it. Measured, not reasoned: the same emission harness run against origin/main and against #6801's head adb3c3ace gives

rows compared: 20, rows whose EMISSIONS changed under PR #6801: 0

⇒ the card is independent of that PR and a change is warranted. Forward-compatibility confirmed too — the new suite run on #6801's tree alongside that PR's own suites: Test Files 3 passed (3) / Tests 117 passed (117).

The divergence reproduces, and the fault is entirely the oracle's

6-of-10 reproduces exactly, and all six are the oracle's fault — the product reads what the browser hands it and is right on all ten rows. So ⛔ no widget source was touched and ⛔ no existing assertion moved, which is the correct outcome for a card about tests lying.

The table's base is a real browser, not an assumption — Chromium 141 via Playwright, a real type="number" input driven key by key, reading .value and validity.badInput after each keystroke:

'12abc' -> ''  '1'  '12'  '12'  '12'  '12'
'1.2.3' -> ''  '1'  '1'   '1.2' '1.2' '1.23'
'0x10'  -> ''  '0'  '0'   '01'  '010'
'1e'    -> ''  '1'  ''     with badInput TRUE

Paste (keyboard.insertText) lands on identical final readings; a programmatic .value write lands on '' for all of them with badInput false.

⭐ And the new suite carries a self-guard: it asserts every string it drives is one the platform reads without validity.badInput — so it cannot regress into the fiction it was written to replace. A test that can decay back into the bug it fixes is a temporary fix; this one is pinned against its own failure mode.

⛔ A second card claim, falsified

"every existing unit test for these widgets drives a string no browser can deliver"

Does not survive re-derivation. Of the 10 test files that render these four widgets, exactly one drives such a string — the divergence pin itself, which exists to record it. Every other one already drives '10', '15', '75', '6000', '2', '1234.56', '1234.567'.

⭐ And the report names where that error came from: the card's own confidence gap 2 — "not a file count I have taken." The gap was declared when the card was filed, and this round closed it by measuring rather than inheriting. That is the confidence-gap mechanism working exactly as intended.

The corrected count is written into the new file's docstring, so the next reader gets the measured number rather than the card's.

Ablation ran on the sibling's tree — the right call

Both mutable widgets are deferred files on this branch, so the ablation was run in a comparison worktree on PR #6801's tree. Leg A (CurrencyField, parseFloat → Math.trunc(parseFloat), null → 0): 3 failed / 22 passed, the reds being currency 1.2.3, currency 1e, and the ten-case six-disagreement derivation. Leg B (NumberField, Number(val) → parseInt(val,10)): 2 failed / 23 passed. Direction predicted before running; red is what came back. Mutations confirmed on disk by grep -cF counts in both directions plus blob-hash inequality; restores proven by hash equality and an empty git diff HEAD.

What remains, and why this card is now blocked

DEFERRED, correctly: rewriting the ten fabricated-string bodies in NumberInputWidgets.environmentDivergence.test.tsx (which #6801 modifies) and folding this PR's keystroke table into numberInputBrowserReadings.ts (which #6801 adds). Both belong to an unmerged PR; editing them would conflict.

⇒ card flipped to pm:blocked with Blocked-by: #6801 and the assignee cleared. The unlock scan returns it when #6801 lands, and the follow-up dispatch is the other half: retire the fabricated bodies and merge the two reading tables into one.

⛔ Note for that round: do not re-measure the browser table. It exists, in this PR, with its provenance.

#6848 filed — clearing a GeolocationField coordinate emits undefined where the other three emit null; undefined keys vanish from JSON, so a cleared coordinate can reach the server as an absent key (conventionally "leave it alone") rather than an explicit null. ⭐ The report is explicit that the measurement is the emission and the persistence consequence is reasoned, not measured — and the issue says so too. Separating what was observed from what was inferred, in the artifact itself, is what makes a finding safe to act on.
