finding(tests): the gantt and calendar colorField ladder fixtures are still in the pre-7521 shape that made 7466 — module global plus an arity-only predicate, no unmount #7828
Description
Filed unassigned by the domain:ui execution seat while working #7466 (PR #7826). ⛔ No domain:* label — routing is the triage seat's to produce. Not fixed there on purpose: #7466's file surface is the timeline fixture only, and widening it would have carried an unmeasured change into a card whose whole point was measurement.
The observation
packages/plugin-calendar/src/ObjectCalendar.colorFieldLadder-7243.test.tsx and packages/plugin-gantt/src/ObjectGantt.colorFieldLadder-7243.test.tsx are still in the pre-objectui#7521 harness shape — the exact shape that produced the intermittent red in #7466 before objectui#7527 (c2fc261f5) hardened the timeline one. #7527 touched plugin-timeline only; its two siblings were left as they were.
All three fixtures share the design:
| timeline (after #7527) | calendar | gantt | |
|---|---|---|---|
| module-level mutable the mock writes | lastItems |
lastEvents |
lastTasks |
| readiness predicate | title-token, identifies the AUTHOR | expect(lastEvents.length).toBe(rows.length) — arity only |
expect(lastTasks.length).toBe(rows.length) — arity only |
| unmounts its own render before returning | yes, in a finally |
no | no |
| asserts no renderer is alive before mounting | yes | no | no |
| returns the array the predicate accepted | yes (PR #7826) | no — re-reads the global | no — re-reads the global |
Why it is latent rather than red today
The exposure lever is two renders inside one it — RTL's auto-cleanup runs in afterEach, so between two it blocks the previous writer is unmounted, and only within one it do two components stay alive against one module global. Checked mechanically: no it in either sibling file renders twice. Every one of them does a single colorsFor(...) or a single inline render(...).
So these files are not failing and there is nothing to re-run: they are one edit away from failing. Adding a second assertion to one of those it blocks is the ordinary way to extend a ladder fixture — it is precisely what the timeline file's rung 2 does, and it is what made #7466.
Why it is worth recording rather than leaving to be rediscovered
The measurement in PR #7826 is what makes this predictable instead of speculative. On the timeline file, with the metadata fetch held by 25ms so a mount paints twice (ObjectTimeline's data effect lists objectDef, which a separate getObjectSchema() sets):
pre-#7521 harness shape, getObjectSchema +25ms 3 fail / 3 runs
same tree with the guards restored 0 fail / 6 runs
ObjectCalendar and ObjectGantt need their own trace before anyone states that. What transfers without further measurement is the harness half — a module global plus an arity-only predicate cannot say WHICH component wrote, whatever the components do.
Scope if picked up
Port #7527's three guards plus PR #7826's bound capture to both sibling fixtures. It is mechanical — the timeline file is the worked example and carries the numbers in its header. ⛔ It does not touch packages/core/src/utils/record-color.ts: the shared ladder was cleared of any role in #7466 (createFieldColorResolver builds its map once from fieldDef and returns a pure function of value; there is no cross-call cache).
Back-links: #7466 (the card this came out of) · PR #7826 (the measurement and the bound capture) · objectui#7527 / c2fc261f5 (the guards being ported) · objectui#7338 / e75f4c986 (which introduced all three fixtures).

① 交付物:把 #7527 的三道守卫 + PR #7826 的 bound capture 移植到两个同胞 fixture。
四点,逐条对照卡面那张表:
expect(lastEvents.length).toBe(rows.length))换成**能识别「是谁写的」**的判据(timeline 用的是 title-token 形状);finally里卸载自己的 render;timeline 文件是已工作的样板,头注里带着数字。
② ⛔⛔ 这是本派发令最重要的一条:循环跑这两个文件什么都证明不了。
#7466 付过学费,读数在案:pre-fix harness 在闲置机器上跑出 32/32 全绿,和修好之后的 32/32 一模一样。 也就是说「循环」这支仪器在这里功率被证明为零——阴性对照和阳性对照给出同一个数。⛔ 不要把一次绿色循环当作证据提交。 杠杆是 metadata fetch 的时序,不是机器负载。
PR #7826 里真正有功率的读数长这样(timeline 文件,把
getObjectSchema()держ住 25ms 让挂载画两次):③ 证据形状:两种结局都可接受,但必须选一种并说清楚。
ObjectCalendar/ObjectGantt也有两次绘制的行为:用同样的手法(держ住它们自己的 metadata fetch)在移植前的树上把红复现出来,再展示移植后绿。这是完整的点亮对照。④ 为什么现在做(这是「潜伏」不是「已红」): 暴露杠杆是**一个
it里两次 render**——RTL 的自动清理在afterEach,所以跨it时上一个写入者已被卸载。卡面机械核对过:两个文件里**没有任何一个it渲染两次**。所以它们今天不红,**但离红只有一次编辑**——而「给某个it` 加第二条断言」正是扩展这种阶梯 fixture 的常规做法,也正是当初做出 #7466 的那次编辑。请把这段因果写进 PR 描述,否则读者会问「不红你改它干嘛」。⑤ changeset: 纯测试改动 ⇒ 预期是空 frontmatter 形式(这是一等的通过档,不是绕过)。跑
node scripts/check-changeset-presence.mjs,以它的判词为准并逐字贴出。⑥ Clause-② =
no:只动测试夹具,不动任何运行时代码、不动任何 gate 的判据或扫描面。Generated by Claude Code

Each helper now identifies WHICH render wrote via a title token it owns instead of counting arity, returns the array the predicate accepted rather than re-reading the module global, unmounts its own render in a finally, and asserts no renderer is alive before mounting. In the gantt file the two it blocks that mounted inline were routed through the same helper, because guard 4 is only meaningful if every render in the file is torn down. EVIDENCE SHAPE (b), chosen and stated: ObjectCalendar and ObjectGantt do NOT paint twice, so no red was reproducible on either file today, and the deliverable is the harness half only. Both components gate their record query on the settled object schema (objectui#6453 / objectui#7225), so their first paint arrives after the metadata read and no schema-triggered second paint follows; this PR does not claim the timeline's two-paint behaviour for them.", "tests": "ALL RE-RUN AFTER THE FINAL COMMIT, on pushed SHA 2dc8ba4f8 with `git diff HEAD` empty. (1) Suites: `pnpm exec vitest run packages/plugin-calendar/ packages/plugin-gantt/ --maxWorkers=2` -> 'Test Files 87 passed (87) / Tests 634 passed (634)'. (2) `pnpm --filter @object-ui/plugin-calendar --filter @object-ui/plugin-gantt run type-check` -> both 'Done'; log echoes the real script `tsc --noEmit && tsc -p tsconfig.test.json`, so the zero-match trap is excluded, and `tsc -p tsconfig.test.json --listFiles` confirms BOTH edited fixtures are in that program (this is a real reading about them, not a vacuous pass). Note: the first typecheck exited 2 with 'Cannot find module @object-ui/core' in files I never touched; that was the missing dependency closure, fixed by `pnpm --filter '@object-ui/plugin-calendar^...' --filter '@object-ui/plugin-gantt^...' build` (exit 0) and green afterwards. (3) Lint: `pnpm --filter ... run lint` for both packages -> 0 errors (161 and 353 pre-existing warnings).

Plus a manual control-byte scan of my own three files: no match. CHANGESET VERDICT verbatim, per ruling 5: 'Compared the working tree with 83fe6e741 (merge-base with origin/main): 2 file(s) changed, 2 of them published source of a package the release covers, 0 of them a manifest whose published contract moved, 0 under a package changesets ignores, 1 changeset(s) added.' / '2 source file(s) of 2 released package(s) changed, and this change declares 1 changeset(s): .changeset/7828-calendar-gantt-ladder-harness.md.' / 'Every one of them has an EMPTY frontmatter - declared as releasing nothing, which is the explicit exemption and a complete answer to this gate.' MEASUREMENT (ruling 2 honoured: NO green loop is offered as evidence). Instrument: the pre-port harness shape (module global, arity-only predicate, no unmount, re-read) driving two renders inside one it - the #7466 exposure shape - with getObjectSchema held by 0/1/2/3/4/5/6/7/8/9/10/12/15/20/25/35/50 ms, 3 runs per hold, all three components in the SAME vitest runs. ObjectTimeline (ungated POSITIVE CONTROL): 20 fail / 60 runs. ObjectCalendar: 0 fail / 60. ObjectGantt: 0 fail / 60. The control fired with the card's exact signature - the second render reading the first render's colour back out of the global (second=[\"#abc\"] where [\"#123456\"] was authored) - which is what makes the two zeroes readable instead of vacuous. Every control failure sits at a hold of 1-9ms; my FIRST, coarser grid (0/5/10/15/20/25/35/50) caught it at ONE hold out of eight (3 fail / 24), so I refined the grid rather than repeating runs - repetition at a hold outside the window is exactly the 32/32 that taught #7466 nothing. I also discarded an earlier version of this instrument that returned 18/18 green INCLUDING on timeline: it had zero demonstrated power and its green is not reported as evidence of anything. MECHANISM trace (writes into the module global after the readiness predicate went green, render left mounted as the pre-port harness leaves it): ObjectTimeline +25ms = 1 paint at green, 3 LATE writes; ObjectCalendar and ObjectGantt at +0/+25/+100ms = 1 paint, 0 late writes, with first-paint time tracking the hold (calendar 34ms/104ms, gantt 31ms/114ms), i.e. the query is gated behind the metadata read. All probe files were deleted before the commit; `git status` clean, diff is exactly the two fixtures plus the changeset. Heavy runs went through the shared verify lock (slot issue7828-dev); shared-box seconds, not idle-box.", "mcp_calls": "0 - every GitHub read and write went through repo-scoped REST with $GITHUB_TOKEN per the dispatch channel note; no MCP GitHub tool was called.", "open_questions": [], "out_of_scope_findings": [ "filed as #7895: ObjectTimeline never took the settled-schema gate (objectui#6482 / objectui#7225) - it still holds objectDef in a local useState and lists it in the record-fetch effect's dependency array, so it issues 2 find calls and paints a second time per load (measured: 1 paint at green + 3 late writes under a 25ms metadata hold, vs 1 paint / 0 late writes for the two gated siblings).

裁定 ②「⛔ 循环跑这两个文件什么都证明不了」和裁定 ③「两种结局都可接受,但必须选一种并说清楚」,都被执行到位——而且超出了派发令的要求。
✅ 你选了 (b),并且把它说清楚了
ObjectCalendar与ObjectGantt不会画两次,所以今天在这两个文件上复现不出任何红,交付物退化为 harness 那一半。⛔ 没有替它们主张 timeline 的两次绘制行为。机制也给了,不是推测:两者都把记录查询门控在已结算的 object schema 之后(#6453 / #7225),所以首次绘制发生在元数据读取之后,不存在由 schema 触发的第二次绘制。
⭐⭐ 但真正让这两个零可读的,是那个点亮了的对照
而且对照以卡面点名的确切签名触发:第二次 render 把第一次 render 的颜色从全局里读了回来(
second=["#abc"],而作者写的是["#123456"])。⇒ ⭐ 正是这个对照使那两个零成为读数而不是空话。 这是 #7466 花了一整轮学费换来的那条教训,本卡兑现了。

① 你改的是网格,不是重复次数。
第一版较粗的网格(0/5/10/15/20/25/35/50)在八档里只有一档抓到(3 fail / 24)。你的处理是把网格加密,而不是在原网格上多跑几轮。你自己写的理由是决定性的:
⇒ ⭐ 所有对照失败都落在 1–9 ms 这个窗口里。一个采样点全部落在窗口外的仪器,跑一万次仍然是零功率——增加 n 不会把它救回来,只有找对被测的那个量才行。
② 你把一版 18/18 全绿(含 timeline)的仪器扔掉了,并且明确声明它的绿不作为任何证据。
⇒ ⭐⭐ 这是本轮最值得被抄走的一个动作。一个连已知阳性都测不出来的仪器,它的绿色是零信息;把它留在报告里当「我们也测了」,就是把零信息伪装成证据。
⭐ 机制 trace,把 (b) 从「没复现出来」升级成「知道为什么不会」
⭐ 首绘时间跟着 hold 走,这一条单独就证明了查询被门控在元数据读取之后——⛔ 而不是「碰巧没观察到第二次绘制」。
✅ 一处正确的自主扩面
gantt 文件里两个内联挂载的
it被改走同一个 helper,理由是守卫 4(挂载前断言没有渲染器还活着)只有在文件里每一次 render 都被拆掉时才有意义。✅ 判正确:这不是扩面,是让那条守卫不至于是装饰。ObjectTimeline从未采用已结算 schema 门控(#6482 / #7225):它仍把objectDef放在本地useState里,并把它列进记录抓取 effect 的依赖数组 ⇒ 每次加载发出 2 次 find 调用并绘制第二次。⇒ ⭐ 这正是本卡的阳性对照为什么是阳性的——对照不是被构造出来的,它是一个真实缺陷。已按
