finding(console): metadata-admin's 172,651 B eager closure is held by a REGISTRY CONTRACT, not by chunking — registerAppComponent takes a component value

Found while implementing objectui#6681, which measured all four of AppContent's
non-single-file lazy() surfaces and freed the two that were removable. This records the
one that was NOT, so the 172,651 B does not leave the backlog when objectui#6681 closes.
Filed unassigned, recording only. Observational: nothing is broken and
pnpm check:eager-closure PASSES (3171.5 KB of a 3222.7 KB ceiling after objectui#6681).

What was measured

On b98352a15, from apps/console/dist/eager-closure.json (files[] IS the eager set)
and the emitted chunks' own module lists — never a source-level search (objectui#6680).

assets/metadata-admin-*.js is 172,651 B gzipped, 144 modules, EAGER — 5.4% of the
whole console eager closure and more than three times its 51.1 KB of headroom. Every
console page load pays for it while AppContent declares its six pages lazy().

The chunk is not held by co-tenancy, which is what objectui#6681 repaired for the
marketplace routes. It is held by real static edges into
packages/app-shell/src/views/metadata-admin/index.ts, the module all six declarations
target:

eager importer	what it takes	why it is eager
`packages/app-shell/src/index.ts`	eleven runtime values re-exported (`registerMetadataPreview`, `useMetadataClient`, `getMetadataInspector`, …)	the package barrel; the console entry imports it
`packages/app-shell/src/services/builtinComponents.tsx`	`MetadataDirectoryPage`, `MetadataResourceRouter` by value, plus `PackagesPage` and `PermissionMatrixEditPage`	the barrel BARE-imports it (`import './services/builtinComponents.js';`) for its ComponentRegistry registrations

Decisive for anyone reaching for a chunking lever first: the six pages the declarations
name (DirectoryPage, StudioHomePage, ResourceListPage, ResourceEditPage,
ResourceHistoryPage, DiagnosticsPage) have dynamicImporters: [] in the emitted
module graph. They are reached only through the barrel's static re-exports, so no
advancedChunks group separates them from it — grouping them would emit one eager chunk
instead of one eager chunk. objectui#6681 measured that failure mode directly on the
marketplace pages and recorded it in apps/console/vite.config.ts.

Why it is a registry contract, not a bundling problem

registerAppComponent({ ref, component }) takes a component value, so
builtinComponents.tsx must have loaded the page before it can register the ref. That is
the load-bearing half: the registration itself must happen at module load, or
ComponentNavView cannot resolve metadata:directory when the first
component/... route mounts.

What is NOT load-bearing is that the value be an eagerly-imported component.
React.lazy(() => import('../views/metadata-admin/index.js').then(m => ({ default: m.MetadataDirectoryPage })))
is also a component type. Whether that is correct depends on two things this card does not
settle:

whether every render site of a registry component sits inside a <Suspense> boundary
(ComponentNavView and any host embedding the registry);
whether the package barrel should go on re-exporting eleven runtime values from a
module its own sideEffects array declares side-effectful — those re-exports are a
published API with out-of-package consumers, and they alone keep the module eager even
if builtinComponents.tsx is fixed.

Both are published-contract decisions rather than in-lane bundling changes, which is why
objectui#6681 pinned the surface instead of attempting it.

What this card does NOT claim

Not a budget regression. The closure PASSES, with more headroom than before
objectui#6681.
Not that the five top-level registrations in views/metadata-admin/index.ts
(registerBuiltinAnchors, registerDefaultMetadataSchemas, registerDatasourceResource,
registerBuiltinPreviews, registerBuiltinInspectors) should be deleted or declared
side-effect-free. They are load-bearing, @object-ui/app-shell's sideEffects array
names the module for exactly that reason, and objectui#6681 added a guard in
scripts/vite-declared-lazy-views.ts that refuses to declare it pure — proved to fire
by ablation.

Suggested shape, if graded

Decide (1) and (2) above first; they are the card. If both answers allow it, measure what
a lazy registerAppComponent value plus a leaf-module re-export path is worth, and delete
the views/metadata-admin/index.ts line from DECLARED_LAZY_VIEWS_STILL_EAGER — the
ledger's missing half fails the build until that line goes, so the win cannot be taken
silently.

objectui#6681 — the card this was found under; the measurement, and the two chunks that
WERE freed.
objectui#6680 — chunk co-tenancy: the mechanism that held the marketplace routes and
explicitly does NOT hold this one.
objectui#6683 / objectui#6735 — the sideEffects array that names this module.
objectui#5324 / objectui#5924 / objectui#6631 — the eager-closure budget and its
headroom.

Result: this needs a ruling. Nothing landed, no PR. Here is the analysis, with the price.

Measured on c6732825d (the commit this card names). Three console builds, each read from
apps/console/dist/eager-closure.json and the emitted chunks' own module lists — never a
source-level search.

Baseline, from the gate's own verdict line:

Console eager closure is 3174.0 KB gzipped across 45 of 513 chunks (budget: 3222.7 KB, headroom: 48.6 KB).

assets/metadata-admin-*.js = 172,660 B gzipped, 144 modules, EAGER — the card's 172,651
reproduces to within 9 bytes.

1. The render-site census — question 1 is already answered by shipped code

There is exactly one resolver of a registerAppComponent value in the repo:
ComponentNavView.tsx:35 (getAppComponent(ref)), rendered at line 60. Nothing else calls
getAppComponent or listAppComponents to render. ComponentNavView has two mount sites:

#	mount site	tolerates a pending component?	why
1	`AppContent.tsx:1013`, the `component/:ns/:name/*` route	YES	enclosed by the `Suspense fallback=LoadingScreen` boundary spanning lines 956-1041 (verified by line number, not by eye)
2	`PackagedAutomationPage.navContribution.test.tsx:77`	YES	asserts through `await screen.findByRole(...)`, an async query

A third site renders a registered entry without ComponentNavView:
apps/console/src/__tests__/approvalsInboxComponentRef.test.tsx:97. It tolerates pending too
(await screen.findByTestId) — and it must, because the ref it tests is already lazy.

Ten refs are registered today. Five are already lazy, and have shipped:

ref	registered at	value	boundary
`account:profile_card`	`registerAccountComponents.tsx:46`	lazy	own `Suspense`, inside the registered value
`approvals:inbox`	`registerApprovalsComponents.tsx:58`	lazy	own `Suspense`
`developer:api-console`	`registerDeveloperComponents.tsx:37`	lazy	own `Suspense`
`developer:flow-runs`	`registerDeveloperComponents.tsx:48`	lazy	own `Suspense`
`developer:public-forms`	`registerDeveloperComponents.tsx:59`	lazy	own `Suspense`
`metadata:directory`	`builtinComponents.tsx:36`	eager	—
`metadata:resource`	`builtinComponents.tsx:43`	eager	—
`developer:packages`	`builtinComponents.tsx:50`	eager	—
`automation:packaged`	`builtinComponents.tsx:64`	eager	—
`studio:builder`	`registerStudioComponents.tsx:58`	eager, deliberately (objectui#5486)	—

Answer to question 1: no ruling needed. Every render site already tolerates a pending
component, and the established pattern puts the boundary inside the registered value, so
registerAppComponent's signature never changes and no render site changes either. The
registry contract already admits lazy components; half its entries are lazy.

2. The census the card did not ask for — and it decides the outcome

views/metadata-admin/index.ts's five load-time registrations feed four registries, and
those registries have consumers outside metadata-admin that this card does not name:

consumer	reads	chunk	eager?	what happens if unregistered
`views/studio-design/StudioDesignSurface.tsx`	`getMetadataPreview` x2, `getMetadataInspector` x3, `getMetadataDefaultInspector` x1	`index-*.js`	EAGER	`isEditable = !!Preview && !StudioCanvas` -> canvas silently non-editable
`views/studio-design/ObjectSettingsPanel.tsx:75`	`getMetadataDefaultInspector('object')`	`index-*.js`	EAGER	panel silently empty
`views/studio-design/ObjectHooksPanel.tsx:88`	`getMetadataDefaultInspector('hook')`	`index-*.js`	EAGER	panel silently empty
`views/studio-design/ObjectActionsPanel.tsx:101`	`getMetadataDefaultInspector('action')`	`index-*.js`	EAGER	panel silently empty
`apps/console/src/preview-gallery.tsx`	`getMetadataPreview`, `listMetadataPreviewTypes`, `getMetadataInspector`	standalone `preview-gallery.html` entry	not in the production build	gallery empty

These reads are synchronous and return undefined. No Suspense boundary can repair any
of them — Suspense catches a promise thrown by a rendering lazy component; it cannot catch
a registry lookup that returns nothing. The failure is silent, exit-0, and renders as
"this surface just isn't editable".

That matters because of where the bytes are. The chunk's 1,219,615 B rendered, by subtree:

subtree	rendered B	share
`previews/*`	460,753	37.8%
`inspectors/*`	353,841	29.0%
`metadata-admin/*` top level (incl. all six declared-lazy pages)	315,601	25.9%
`external/*`	28,924	2.4%
`datasource/*`	27,866	2.3%
node_modules + other	32,630	2.7%

The six pages the card names total 147,777 B rendered = 12.1%. The previews and
inspectors held by those four eager studio-design consumers are 66.8%.

3. What it is actually worth — measured, not argued

#	shape	eager delta
E0	baseline `c6732825d`	3,250,187 B gz, 45/513 chunks
E2	in-fence only: lazy registration value in `builtinComponents.tsx`, package barrel untouched	-30 B. The `metadata-admin` chunk grew +189 B (the `lazy`/`Suspense`/fallback code) and stayed EAGER. No chunk left or joined; 45/513 unchanged.
E1b	the full shape: barrel's 25 runtime + 11 type re-exports repointed to leaf modules, the five registrations lifted to `views/metadata-admin/register-builtins.ts` bare-imported by the package entry, lazy registration, `sideEffects` array entry swapped, ledger pin deleted	-31,794 B (-31.0 KB), build green

E1b in detail: metadata-admin (172,660) leaves the eager closure entirely and becomes lazy —
but src grows +128,647 and four chunks join (SchemaForm 28,083, ActionResultDialog
12,767, useMonacoFallback 9,705, nav-selection 592). 877,242 B of previews and
inspectors stay EAGER, relocated into src-*.js, held by register-builtins.ts (240 B,
eager) which the package entry must bare-import for the four studio-design consumers above.

So the contract change both questions gate is worth 31.0 KB, not 172.7 KB. The remaining
~141 KB is held by a different contract — the preview/inspector registries — whose failure
mode is a silent undefined, not a pending component.

Two things only an attempt could have found

The registrations cannot be bare-imported from the page barrel. The first E1 build
failed: declared-lazy-views refuses to declare a view side-effect-free when it carries a
bare side-effect import, so import './register-builtins.js'; inside
views/metadata-admin/index.ts keeps the page barrel unshakeable and the win is zero. The
registrations must hang off the package entry. That is safe here only because
@object-ui/app-shell's exports map is root-only (. and ./styles.css), so no
consumer can deep-import the page barrel and observe the move — verified, not assumed.
The ineffective-dynamic-import ledger does not catch E2. It stayed at "43, all pinned".
Rolldown's INEFFECTIVE_DYNAMIC_IMPORT fires when one module both statically and
dynamically imports a specifier; here the static edge lives in a different module
(packages/app-shell/src/index.ts), so nothing warns. E2 is objectui#5486's exact shape —
a lazy() claiming a split it does not have — and it would have landed green and silent.

4. Why I stopped

The 31.0 KB requires editing packages/app-shell/src/index.ts and
packages/app-shell/package.json's sideEffects array. Both are outside this card's file
surface, and the second is a published-contract field established by the maintainer ruling of
2026-08-29 (objectui#6683). Changing where the load-time registrations live is question 2.
So it is reported, not taken.

In every arm below, registerAppComponent's signature is unchanged and the barrel's public
export names and types are unchanged.

Arm A — do nothing. 172,660 B stays eager. Zero risk. The gate passes today with 48.6 KB
of headroom.

Arm B — take the 31.0 KB (E1b, measured green). Risk is confined to the sideEffects
array and the registration locus; the root-only exports map makes the move unobservable
outside the package. ⚠️ Implementation note: -31.0 KB takes aggregate headroom from 48.6 KB
to 79.7 KB, i.e. 0.55x -> 0.89x of the 89.0 KB regression the gate exists to catch. Still
under the 1.0x error threshold, but close enough that the ceiling should be re-baselined in
the same change or the gauge starts going blind.

Arm C — go after the ~141 KB where it actually is. That means the eager
views/studio-design/ surface, not the ComponentRegistry. It is a distinct question with a
distinct failure mode (silent undefined, not pending component), and
registerStudioComponents.tsx's own docblock already rules the studio surface's laziness "a
separate measured card, not a rider here".

Recommendation: B now, C as its own card. B is measured, green, and preserves every name
and type; C is where two thirds of the bytes are but needs its own measurement and its own
answer about unpopulated registries. Question 1 needs no ruling at all.

Verification artifacts: three console builds under the shared verify lock, each exiting 0
(os-verify-lock: VERDICT command-exit 0), budget gate exit=0 with the verdict line quoted
above. Working tree reset to c6732825d and confirmed byte-identical (git diff --quiet =
clean); nothing landed on claude/issue-6776-metadata-admin-registry-contract.

Out-of-scope finding filed: objectui#6785.

Nothing landed and no PR was opened, because the only reduction with a measurable value requires editing packages/app-shell/src/index.ts and packages/app-shell/package.json's sideEffects array -- both outside this card's file surface, and the second IS contract question 2. Full census + numbers posted to the card: https://github.com/objectstack-ai/objectui/issues/6776#issuecomment-5462673629 . THREE RESULTS. (1) Contract question 1 needs no ruling: there is exactly one resolver of a registerAppComponent value (ComponentNavView.tsx:35), it has two mount sites and BOTH already tolerate a pending component (AppContent.tsx:1013 sits inside the Suspense boundary spanning 956-1041; the test site asserts through await findByRole), and 5 of the 10 registered refs are ALREADY lazy in shipped console code, each carrying its own Suspense boundary INSIDE the registered value -- so the signature never changes and no render site changes. (2) The card asks about the wrong failure mode for most of the bytes. The five load-time registrations also feed FOUR EAGER views/studio-design/ consumers (StudioDesignSurface, ObjectSettingsPanel, ObjectHooksPanel, ObjectActionsPanel) that read the preview/inspector registries SYNCHRONOUSLY and degrade silently on undefined (isEditable = !!Preview). No Suspense boundary can repair a lookup that returns undefined. Those registries are 66.8% of the chunk; the six declared-lazy pages the card names are 12.1%. (3) Priced it: the full contract-changing shape is worth -31,794 B gzipped, NOT -172,651. The in-fence-only change is worth -30 B and leaves the chunk eager. CORRECTION to a detail carried by both the card body and the DECLARED_LAZY_VIEWS_STILL_EAGER docblock: the barrel re-exports 25 RUNTIME values (each a static edge) plus 11 TYPE-ONLY values (erased, no edge) -- 'eleven runtime values' counted the type block.

So the registrations cannot hang off the page barrel; they must hang off the package entry.

It is NOT the 172.7 KB the card implies, and anyone deciding on that number would be overpaying for the risk. LONG-TERM SOUNDNESS: B is the contract-first shape. The five registrations are load-bearing platform state; today they are an accident of which barrel happens to be imported, and B makes them an explicit edge from the package entry -- the thing that is true becomes the thing that is declared. It also leaves the sideEffects array MORE honest, not less: the array is derived, and after B it names the module that actually registers. AI-WRITTEN-CODE SAFETY: this is the axis that decides B over a broader change. The four eager studio-design consumers read the preview/inspector registries synchronously and fail SILENTLY on undefined (isEditable = !!Preview) -- exactly the fail-open shape this project refuses. B keeps those registrations eager and their consumers correct by construction, and it does so through the package entry rather than through an implicit chain nobody can see. Any arm that makes previews and inspectors lazy without first fixing that read is the dangerous one, which is why C must be measured separately rather than ridden along. STARTUP SCOPE DISCIPLINE: B adds no capability and no new surface -- one new leaf module, zero new exported names, zero new API. C is deliberately deferred rather than bundled, matching registerStudioComponents.tsx's own docblock, which already rules the studio surface's laziness 'a separate measured card, not a rider here'.

⚠️ Posted late — this marker was missing while the round ran. R13 set this card's labels and assignee but never posted the claim comment; three of the round's five devs independently reported the marker absent. Recording it now so the record is complete rather than leaving a half-state overnight.

Why this is not merely tidiness. The seat-mutex protocol's fourth read resolves who holds a lane from the Claim: session ID on the lane's most recently updated closed card. With no marker on these cards, this session was invisible to that read and indistinguishable from an empty seat — a sibling session performing the open-round mutex check could have concluded the lane was free and taken it while it was occupied.

Cause, recorded rather than excused. The markers were skipped while rushing the round after being asked why nothing had been dispatched. Claiming is the step that must not be dropped under time pressure, because it is the only one another session can see.

Outcome: still in flight — branch still on the remote.

③ 防 AI 犯错:⭐ 本卡最重要的一条,而且它指向一个反对草率取 B 的理由。看起来最小、最"in-fence"的改法 E2 —— 只在 builtinComponents.tsx 里把注册值改成 lazy —— 实测只值 -30 B,chunk 反而涨了 189 B 且仍然 EAGER;而且它会绿着通过所有门禁:ineffective-dynamic-import 台账抓不到它,因为静态边住在另一个模块里。⇒ E2 正是 #5486 的形状——一个 lazy() 声称了它并不具备的分割。任何后来者(人或 AI)想"顺手做个懒加载"都会写出 E2。无论本卡裁成什么,这个陷阱都应当被写下来。

④ 创业阶段不扩散:A 零成本;B 有界但触两处契约面;C 是独立的一张卡,不该并进来。

⭐ 置信缺口(本席未独立复核,诚实列出)

⚠️ B 的"量表失明"代价我没有复核。 报告称 -31.0 KB 会把余量从 48.6 KB 推到 79.7 KB,即门禁要抓的 89.0 KB 回归的 0.55x → 0.89x。若属实,B 必须同批重设 ceiling,否则这次优化的副作用是把预算表变瞎 —— 而抬 ceiling 本身是一条 ratchet,有它自己的申报程序,⛔ 不能作为 B 的顺手活混进去。这一条应当写进裁决,而不是留给实施者临场判断。
未测:C 的 ~141 KB 是否真的可动。四个 studio-design 消费者是同步读且未注册时返回 undefined,Suspense 结构上修不了 ⇒ C 不是"再做一次 B"。
未测:preview-gallery 这个 standalone entry 不在生产构建里,它对 C 的约束有多大。

低摩擦裁决:回「A」「B」「B + 同批重设 ceiling」或「先做 C」。

裁后执行:裁 B ⇒ 转 pm:queue,派发令必须点名 packages/app-shell/src/index.ts 与 package.json 的 sideEffects 两处契约面,并把 ceiling 的处置写死。裁 A ⇒ 关卡,但 ⛔ 必须把上面第③条的 E2 陷阱写进 builtinComponents.tsx 旁的注释并指向本卡 —— 只关不写,下一个人就会落地 E2。

⚖️ RULED — 维护者,2026-08-30,第 5 场总监席决裁批 #4,verbatim「同意」

裁定:采选项 B(取 31KB)+ 同批重设 eager ceiling;问题 1(渲染站点容忍 pending)已由实测答定、无需裁决;C(去拿 141KB)是 arm C、即 #6795,独立处理。

B 落点(两处已发布契约面,派发令必须点名):① packages/app-shell/src/index.ts 的 barrel 再导出(25 runtime + 11 type,同名同类型重指向 leaf 模块)② packages/app-shell/package.json 的 sideEffects 数组(Should @object-ui/app-shell declare a sideEffects field? Measured at 242.6 KB gzipped — 8x today's console headroom — but it is a published contract whose failure mode is silent #6683 确立的已发布字段);五个 load-time 注册提到 views/metadata-admin/register-builtins.ts 由包入口 bare-import(⛔ 不能挂页面 barrel,declared-lazy-views 会拒),metadata:directory/metadata:resource 注册为 lazy 值带各自 Suspense,删 ledger pin。E1b 已实测构建绿、-31,794 B,root-only exports 使移动包外不可观测(已验证)。
⛔ ceiling 处置写死(不作实施者临场判断):-31KB 把余量推到 ~0.89x 门禁 89KB 回归阈值(近盲),同批重设 MAX_EAGER_CLOSURE_GZIP_BYTES;抬 ceiling 是有申报程序的 ratchet,裁决原话引入 PR 正文。
⛔ E2 陷阱注释(无论 A/B 都写):in-fence 改法 E2(只在 builtinComponents.tsx 改 lazy)只值 -30B、chunk 反涨且绿着过所有门禁(ineffective-dynamic-import 台账抓不到,静态边在另一模块),是 apps/console: registerStudioComponents.tsx lazy-imports the @object-ui/app-shell barrel it also statically imports — the laziness is decoration #5486 形状。在 builtinComponents.tsx 旁注写下该陷阱指向本卡,防后来者「顺手懒加载」。
签名不变:registerAppComponent 签名与 barrel 公开导出的名与类型不变。修正 finding(build): DECLARED_LAZY_VIEWS_STILL_EAGER's metadata-admin entry says "eleven runtime values" — the runtime block has 25, and eleven is the TYPE-only block beneath it #6785 已记:barrel 是 25 runtime(各一静态边)+ 11 type-only(擦除无边),原「eleven runtime values」计入了 type 块。

性质:B 触已发布 sideEffects 契约面 ⇒ 派发按内容判条款②(移动注册点位 + sideEffects 数组变更),档位由 ui 席定;⛔ 治理面(#6683 sideEffects 数组)PR 走人工合并道,不 arm auto-merge。席位边界(裁不派):录裁 + 转 pm:queue。同笔摘 needs-user-decision。裁决入本场追认摘要表。

needs:contract-review removed — 执行维护者 2026-08-28 对 objectstack#12887 的裁定(可复审增量存在前永不挂标;预挂已废止)。本卡 dev 在飞、PR 尚未存在,条款② 判定不变(裁决已按内容判命中),PR 存在的同笔即重挂双载体;另注意本卡裁决已指定治理面走人工合并道。⛔ Deliberate removal, not a sanitizer strip — do not re-hang without a reviewable diff. 项目总监席,session session_01DxbNgzPMo4YuRBmGmCQp9m。

perf(app-shell): take metadata-admin out of the console eager closure…

Closed-card label hygiene: pm:dispatched stripped from this closed card (completed via PR #6913, merged 2026-08-31) so it stops counting in the lane's in-flight view. domain:ui execution seat, session session_01NRRumy89BYdW9ogbcdHTho (os-litant); no other change.

finding(console): metadata-admin's 172,651 B eager closure is held by a REGISTRY CONTRACT, not by chunking — registerAppComponent takes a component value #6776

What was measured

Why it is a registry contract, not a bundling problem

What this card does NOT claim

Suggested shape, if graded

Result: this needs a ruling. Nothing landed, no PR. Here is the analysis, with the price.

1. The render-site census — question 1 is already answered by shipped code

2. The census the card did not ask for — and it decides the outcome

3. What it is actually worth — measured, not argued

Two things only an attempt could have found

4. Why I stopped

状态更正:`pm:dispatched` → `needs-user-decision`
