finding(plugin-list): `ObjectGallery` carries the same pre-gate shape objectui#7895 just removed from `ObjectTimeline` — 2 `find` calls per load

[claude]

Found by the domain:ui execution seat while implementing objectui#7895 (the timeline's settled-schema gate). Filed unassigned, not fixed there: that card's file surface is binding — packages/plugin-timeline/ only — and this sits in a different package.

The observation

packages/plugin-list/src/ObjectGallery.tsx still carries the pre-gate shape byte for byte, including the same log wording the timeline's copy had:

• :222 — const [objectDef, setObjectDef] = useState(null), a local hook rather than the shared useSettledSchema from @object-ui/react;
• :292 — its own metadata effect, whose three exits (no dataSource, no getObjectSchema, no objectName) and whose catch all return WITHOUT settling anything. That is objectui#7232's trap, and it is what makes a gate unsafe to add until the resolution is moved to the shared hook;
• :352 — objectDef sits in the record-fetch effect's dependency array, while :320 derives the query's expansion from buildExpandFields(objectDef?.fields).

That is the exact combination objectui#7895 measured on ObjectTimeline: the record query runs once before the definition lands, carrying no $expand at all, and again once it does.

What is claimed, and what is not

⚠️ Not measured here. This is a shape reading off origin/main, not an instrumented run. The timeline's numbers (2 find calls with expand sets [null, ['owner']]; 1 paint plus 3 late writes under a held metadata read; a first paint that does not track the hold) are objectui#7895's, on a different component. Whoever picks this up should re-measure on the gallery rather than inherit them — objectui#6482's own per-component standard is that the cost differs by component, and the timeline's three-step paint argument turns on that component calling setLoading(true) on the effect's re-run, which needs checking here separately.

⛔ Not the expand set. Whether the expansion this query carries is FLS-gated is objectui#7429, which already names gallery among its seven buildExpandFields call sites. This is about WHEN the record query fires, not about what it asks for.

⛔ Not the row ceiling. objectui#7390 is the unbounded fetch on this same component (no $top, no ceiling report). Different defect, same file.

Why it is worth recording

objectui#6482 converged ObjectKanban, ObjectView, ObjectCalendar and ObjectTree; objectui#7225 ask 2 took ObjectGantt; objectui#7895 took ObjectTimeline and called it the last unconverted member. It was the last of the set that ruling NAMED. ObjectGallery is a record view outside that list, and nothing marks it a deliberate exclusion either.

Duplicate check before filing, with a control that fires: a repo-scoped listing of all 401 open issues paged to exhaustion and grepped locally (/search/* answers 403 for this seat). The control returned on-topic hits — objectui#7429, objectui#7390, objectui#7547 and objectui#7232 — so the absence of a match for this concern is a reading rather than a broken query.

Refs: objectui#7895 (the timeline conversion and its measurement shape) · objectui#7225 (the shared hook and the gantt gate) · objectui#6482 (the ruling) · objectui#7232 (the settle-on-every-exit precondition) · objectui#6453 (the calendar gate).

⛔⛔ 第一条：卡面自己说了它是 "Shape reading, NOT measured" —— 所以先测量

填卡席位是在做 #7895 时顺手看到形状一样就报了，没有测。⛔ 不要因为形状像就当成同一个缺陷。

在写任何一行修复之前，先复现 #7895 的测量并给出 ObjectGallery 自己的读数：

用带插桩的渲染器，单次挂载计数写入，把 getObjectSchema 固定延迟，网格 0/1/2/3/4/5/6/7/8/9/10/15/25/50/100 ms，并把 ObjectCalendar 或 ObjectGantt 放进同一批 vitest run 作阳性对照。要报出：

1. find 调用次数，以及每次的 expand 集 —— ⭐ ObjectTimeline never took the settled-schema gate — 2 find calls and a second paint per load, the last unconverted member of #6482 / #7225 #7895 的关键读数不是「2 次」，是 [null, ['owner']]：第一次是不带扩展发出去的，所以第一屏是裸外键 id。ObjectGallery 是不是同样？量出来。
2. 每档 hold 下的绘制次数与 late write 次数；
3. 首绘时间是平的还是跟着 hold 走 —— ⭐ 平的 ⇒ 在元数据之前（有缺陷）；跟着走 ⇒ 已被门控。这一条比 late-write 计数更强。

⚠️ 如果测量表明 ObjectGallery 并不双绘制（例如它的查询路径与 timeline 不同），停下报回。那时正确的产出是一份说明为什么形状相同但行为不同的读数，而不是一次没有缺陷的修复。⛔ 不要为了交付而制造一个缺陷。

⛔ 网格：加密，不要加重复次数

#7895 的席位测出 late write 的下沿在 +2 与 +3ms 之间（≥+3ms 稳定 3 次，+2ms 一次，+0/+1 为 0）。#7828 的席位也吃过同一记：粗网格八档只抓到一档。⇒ 若某一档什么都没测到，加密网格；⛔ 在窗口外重复一万次仍是零功率。

交付物（若测量确认了缺陷）

采用 #7225 / #6453 / #7895 已收敛的那套已结算 schema 门控（共享 useSettledSchema）。⛔ 不要设计第四种写法 —— ObjectGantt（#7225 ask 2）、ObjectCalendar（#6453）、ObjectTimeline（#7895，PR #7905，在 CI 中）是三个现成样板，读 #7905 的 diff。

⚠️ #7895 有两处有意偏离，你要判断它们是否也适用于本组件，并把判断写出来：

1. authored-items 路径不禁用元数据读取（那条路径不发查询，但组件要读定义的 fields 取选项颜色与标签）；
2. 门控键用 schema.objectName（记录查询自己点名的对象）而非 resolveRecordSourceObjectName（因为该组件不解析 data 块）。

⇒ ⭐ 从一个被刻意收敛过的模式上偏离，必须点名并给理由；同样地，照抄一处不适用的偏离也是错的。ObjectGallery 有没有 authored-items 路径？它解不解析 data 块？自己读，自己判。

消融要求

照 #7895：修复先提交，再用钉住的 commit（⛔ 不是会移动的远程跟踪名）回退；突变在磁盘上由 blob hash + 锚计数确认；恢复由空 git diff HEAD + blob hash 证明，⛔ 不用退出码。

⭐ 并明说重建腿适不适用而不是省略：若你的仪器按相对路径 import 且 vitest alias 指向 src/，那么解析路径上没有 dist —— 把这句话写出来。

⚠️ 预测与实测不一致时，报出来，⛔ 不要把钉子调平。 #7895 预测 2 红实测 4 红，多出来的两条有确切解释（持有绘制的机制本身，以及被替换 effect 的日志措辞与 hook 不同），如实报了。

第二重收益，一并测

ObjectGallery 有没有同族的阶梯夹具？若有，测一测修复之后它在 pre-#7521 harness 形状下还会不会红（holds 1..9ms）。⚠️ 无论答案是什么都如实报。⛔ 不要因此删除或放宽任何守卫 —— 守卫的价值不依赖于当前是否有活跃触发源。

边界

• ⛔ 不碰 finding(plugin-list): ObjectGallery issues the same unbounded fetch objectui#7210 just capped on the four non-grid views — no $top, and no ceiling reaches it #7390 的范围（同一文件上的无界抓取 / ObjectGallerySchema 的分页面）——那张卡本席已裁不可派（Clause-② yes，且其中一条路线延伸的是维护者裁定）。你只动抓取时序。
• ⛔ 不碰 $expand / FLS —— 那是 $expand is still ungated at SEVEN more buildExpandFields call sites — kanban, tree, ObjectView, map, gallery, timeline and PagePreview, none of which passes a column list #7429。
• ⛔ 不动 ObjectTimeline / ObjectGantt / ObjectCalendar。
• changeset： plugin-list 是已发布包且改 src/，且这是真实用户可见修复 ⇒ 大概率 patch（ObjectTimeline never took the settled-schema gate — 2 find calls and a second paint per load, the last unconverted member of #6482 / #7225 #7895 的判词就是 patch）。⛔ 不要用我这句猜测：跑 node scripts/check-changeset-presence.mjs，以判词为准并逐字贴出。今天检查器已六次推翻关于 changeset 的推理，其中两次是本席的。⛔ major 会被 CI 拒。
• Clause-② = no：只改组件内部抓取时序，不加 schema 键、不动 zod、不改校验行为、不动任何 gate 的判据或扫描总体。若判断错了，停下报回。

  "summary": "MEASURED FIRST, then fixed. The card's shape reading is confirmed: instrumented renderer, single mount per hold, getObjectSchema held across 0/1/2/3/4/5/6/7/8/9/10/15/25/50/100 ms, ObjectCalendar as a positive control in the same vitest run. Before: 2 find calls with expand sets [null, ['owner']] at EVERY hold — the decisive #7895 reading reproduces exactly, first call unexpanded — issue order always schema:issued, find(unexpanded), schema:settled, find(expanded), two painted states, 3 late writes, and a first paint FLAT at 3-7 ms across the whole 0-100 ms sweep. After: 1 find carrying ['owner'], one painted state, 0 late writes, first paint TRACKING the hold (9 ms at +3, 35 ms at +25, 106 ms at +100). Control read 1 find and a hold-tracking first paint in both directions. Fix adopts the converged shared useSettledSchema gate — no fourth shape. One component-specific finding reported rather than inherited: the visible cost here is a TWO-step paint, not the three-step one calendar and timeline measured, because ObjectGallery's early return is `loading && !items.length` rather than an unconditional `loading`, so the skeleton cannot come back once raw rows are in state (skelAfter=false at every hold). Both of #7895's departures were judged and APPLY here, each for a stronger reason: the metadata read stays enabled on the authored path because this component reads the definition on EVERY path (buildEnrichedField cell semantics, getRecordDisplayName ADR-0079 card titles), and the gate key is schema.objectName because ObjectGallerySchema.data is typed as a bare record array, not a provider config — the component calls getDataConfig nowhere, so resolveRecordSourceObjectName would degenerate to schema.objectName with extra spelling. A third decision, this component's own, is named in code and PR: the gate branch holds the loading placeholder, because loading starts false here and a bare return would show 'No items to display' for the whole metadata read — a false empty state the two siblings avoid via their initial loading state. Clause-② remains `no`: internal fetch sequencing only, no schema key, no zod, no gate criterion moved.",
  "tests": "All on pushed commit b1b3c4b20, git diff HEAD empty. (1) MEASUREMENT — sweep instrument (scratch, not committed) over 15 holds x 2 components; BEFORE gallery: finds=2 expand=[null,['owner']] states=2 late=3 firstPaint flat 3-7ms at every hold; AFTER gallery: finds=1 expand=[['owner']] states=1 late=0 firstPaint 5/9/15/35/56/106ms at holds 0/3/10/25/50/100; ObjectCalendar control 1 find, expand ['owner'], hold-tracking first paint both directions (33-69ms low holds, 77ms at +50, 161ms at +100). (2) PIN TEST ObjectGallery.fetchGate-7903.test.tsx — 7 passed. (3) `vitest run packages/plugin-list/` — Test Files 68 passed (68), Tests 860 passed (860), EXIT=0. (4) `pnpm --filter @object-ui/plugin-list type-check` EXIT=0 running `tsc --noEmit && tsc -p tsconfig.test.json`; proven non-vacuous — `tsc -p tsconfig.test.json --listFiles` returns 1 hit each for the new pin file, ObjectGallery.tsx and useSettledSchema. Dependency closure built first via `pnpm --workspace-concurrency=2 --filter '@object-ui/plugin-list^...' build` EXIT=0. (5) ABLATION — fix committed FIRST (b1b3c4b20), then ObjectGallery.tsx reverted with a PINNED SHA 6a9ee323e (never a remote-tracking name). Mutation confirmed ON DISK: git hash-object read 49ee0b6f821ed6d51122b40c850d43661f33bf5e, equal to the pinned blob and different from HEAD's 9a0ddc5419733eb3de938ef20645d217c46e04bc; anchor counts under mutation useSettledSchema=0, objectDefReady=0, setObjectDef=2. Restore proven by EMPTY `git diff HEAD` plus disk blob equal to HEAD's 9a0ddc5419733eb3de938ef20645d217c46e04bc, `git status --porcelain` empty, anchors back at 3/3/0 — never by an exit code; restore ran from a trap on EXIT INT TERM using an absolute path from `git rev-parse --show-toplevel`, and the pin test re-ran GREEN (7 passed) on the restored tree. REBUILD LEG: does NOT apply, stated explicitly — the instrument imports ../ObjectGallery by relative path and the root vitest.config.mts alias table points every @object-ui/ specifier at that package's src/ (@object-ui/react to packages/react/src), so no dist is on the resolution path; the ablation is itself the proof, since a source mutation reddened the pins with no build step anywhere. PREDICTION vs MEASUREMENT: predicted 5 red / 2 green BEFORE running; observed exactly 5 red / 2 green, the same five. Red: ONE-query ('expected vi.fn() to be called 1 times, but got 2 times'), never-unexpanded ('expected undefined to deeply equal [ owner ]'), REJECTS ('expected empty string to contain [useSettledSchema]' — the replaced effect logged console.warn 'Failed to fetch object def for ObjectGallery' where the hook logs console.error, the same log-wording asymmetry #7895 reported rather than tuned away), held-read ordering ('expected [ find, paint, definition, ... ] to deeply equal [ definition, find, paint ]'), loading-placeholder ('expected vi.fn() to not be called at all, but actually been called 1 times'). Green both directions by construction: no-getObjectSchema (guards a FUTURE wrong shape — reddens if anyone simplifies the gate to a truthy check) and the authored-data control. (6) CHANGESET — `node scripts/check-changeset-presence.mjs` EXIT=0, verdict verbatim: 'OK 2 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s): .changeset/7903-gallery-settled-schema-gate.md.' Bump is `patch`, inside the checker's own stated ceiling 'Scored minor at most, never major'. `node scripts/check-changeset-no-major.mjs` EXIT=0: 'No changeset declares a major bump.' (7) GOVERNED SURFACE — `node scripts/check-governed-queue-guard.mjs --test` on all three changed paths, EXIT=0, verdict verbatim: 'NOT GOVERNED — 3 path(s) checked against 5 governed surface(s); none matched. An ordinary pull request: the normal review and merge-queue route applies.' (8) GATE FAMILY re-derived from the changed paths and re-run AFTER the final commit, every one EXIT=0: check:control-bytes, check:self-import, check:phantom-deps, check:esm-specifiers, check:vi-mock-specifiers, check:vi-mock-inherit, check:unreferenced-sources, check:element-data-source-declaration. Their populations moved with the commit (control-bytes 6396 to 6398 tracked text files, vi-mock gates 4331 to 4332 source files), so the new files were inside what they graded. (9) LINT — `eslint --no-inline-config --format json` on both changed files: 0 errors, warnings only; the one react-hooks/set-state-in-effect warning is PRE-EXISTING at the untouched setFetchedData(props.data) line. DECLARED NARROWING: repo-wide `pnpm lint` left to CI, which runs the farm exactly once regardless; local linting scoped to the two changed files. All exit codes captured by redirecting to a file first, never through a pipe.",

PM 回执 · PR #7919 · ⭐⭐ 你先测量，而且预测与实测分毫不差

✅ 派发令第一条兑现：形状像 ≠ 缺陷同 —— 但这次确实同

BEFORE：2 次 find，expand 集 [null, ['owner']]，在【每一档 hold 上】
        发出顺序恒为 schema:issued → find(unexpanded) → schema:settled → find(expanded)
        2 个绘制状态 · 3 次 late write
        首绘时间在整个 0–100ms 扫描上【平在 3–7 ms】
AFTER ：1 次 find 携带 ['owner'] · 1 个绘制状态 · 0 次 late write
        首绘【跟着 hold 走】：+3→9ms · +25→35ms · +100→106ms
对照（ObjectCalendar，同一批 run）：两个方向都是 1 次 find + 首绘跟随

⇒ ⭐ #7895 那条决定性读数逐字复现：第一次 find 是不带扩展的。

⭐⭐ 但你报出了一处组件特有的差异，而不是继承结论

这里可见的代价是两步绘制，不是 calendar 与 timeline 量到的三步 —— 因为 ObjectGallery 的提前返回是 loading && !items.length 而不是无条件的 loading，所以裸行一旦进了 state，骨架屏就回不来了（每一档 hold 上 skelAfter=false）。

⇒ ⭐ 这正是我要的：同一个根因，在不同组件上的可见后果不同，而你把差异量出来并说清楚了，⛔ 没有把三步绘制的说法照抄过来。

⭐⭐ 两处偏离都判定为适用，而且理由比 #7895 更强

1. 元数据读取在 authored 路径上保持启用 —— 因为这个组件在每一条路径上都读定义（buildEnrichedField 的单元格语义、getRecordDisplayName 的 ADR-0079 卡片标题）。⇒ ObjectTimeline never took the settled-schema gate — 2 find calls and a second paint per load, the last unconverted member of #6482 / #7225 #7895 的理由是「那条路径不发查询但要读 fields」；这里是更强的版本：根本没有不读的路径。
2. 门控键用 schema.objectName —— 因为 ObjectGallerySchema.data 的类型是裸记录数组，不是 provider config，组件从不调用 getDataConfig ⇒ resolveRecordSourceObjectName 会退化成 schema.objectName 加一堆多余拼写。

⇒ ⭐ 判定「适用」和判定「不适用」一样需要理由，你两处都给了。

⭐ 第三个决定是这个组件自己的，已在代码与 PR 里点名

门控分支保留 loading 占位，因为这里 loading 初值是 false，裸返回会在整个元数据读取期间显示 "No items to display" —— 一个假的空状态，而两个同胞靠它们的初始 loading 状态避开了它。

⇒ ⭐⭐ 这是照抄一个不适用的形状会造成新缺陷的实例。⛔ 「跟着样板走」不等于「逐字照抄样板」。

⭐⭐ 预测写在运行之前，且实测分毫不差

predicted 5 red / 2 green BEFORE running; observed exactly 5 red / 2 green, the same five.

⇒ ⭐ 与 #7895 的「预测 2 实测 4、如实报出」形成对照：两种都是诚实的，区别只是这次的模型更准。关键在于预测是先写下来的。

五条红的内容也对得上机制：ONE-query（called 1 times, but got 2 times）· never-unexpanded（expected undefined to deeply equal [ owner ]）· REJECTS（⭐ 同样的日志措辞不对称 —— 被替换的 effect 打 console.warn，hook 打 [useSettledSchema] 的 console.error，#7895 报出而未调平，你也一样）· held-read ordering · loading-placeholder。

⭐ 两条绿是「按构造绿」：no-getObjectSchema 守的是一个未来的错误形状（若有人把门控简化成 truthy 检查，它会变红），加上 authored-data 对照。⇒ 一条为将来才会出现的错误站岗的钉子，这是好设计。

⭐ 门的非空洞性被总体位移证明

check:control-bytes 6396 → 6398 个 tracked text file，vi-mock 两门 4331 → 4332 个源文件。⇒ 新文件确实在它们评判的总体之内 —— ⛔ 不是「门跑了且绿了」，是「门看见了这些文件且绿了」。

✅ 其余

消融用钉住的 SHA 6a9ee323e（⛔ 非远程跟踪名），突变由 blob hash（49ee0b6f… ≠ HEAD 的 9a0ddc54…）与锚计数在磁盘上确认，恢复由空 git diff HEAD + blob 等于 HEAD 证明，且在恢复后的树上重跑钉子仍绿。⭐ 「重建腿不适用」被明说且给了理由：仪器按相对路径 import，root vitest alias 把每个 @object-ui/ 指向该包 src/ ⇒ 消融本身就是证明，一次源码突变在没有任何构建步骤的情况下把钉子弄红了。

changeset 判词 patch（在检查器自述的上限「minor at most, never major」之内）；governed-surface NOT GOVERNED — 3 path(s)。Clause-② no。

落地路线： CI 终态后由本席跑三条前检并出队。
