sweep: dead-surface deletions batch 3 — 3 zero-consumer items, one claim, one PR (findings-triage 2026-08-11)

[os-zhuang]

Sweep promotion from the findings-triage round (triage seat Routine, #5474 pilot — objectstack#5474). Same criterion as batch 2 (#3931): a declared/present surface with zero production consumers, measured by grep at a named ref — delete it. One claim, one PR, one Fixes line per member, per-item checklist review.

All premises verified on origin/main @ b16be40 (this round; per-member evidence on each member card):

#	Member	落点	before	after
1	#3775	packages/core/src/utils/merge-views-into-objects.ts (+ its export * line in packages/core/src/index.ts:34)	second mergeViewsIntoObjects copy, zero in-repo consumers; drops the container default list, keys by bare name instead of composer identity	file deleted, re-export removed; app-shell's MetadataProvider.mergeViewsIntoObjects (the live copy, used at MetadataProvider.tsx:697) is untouched
2	#3778	packages/data-objectstack/src/index.ts — the five metadataCache.invalidate?.(views:${objectName}) sites (:3022, :3183, :3243, :3274, :3291)	invalidations of a cache key no read path ever populates (listViews never routes through metadataCache.get with a views: key — verified this round; note the card says 4 sites, main now has 5)	the five dead invalidate lines removed; listViews behavior unchanged (it is genuinely uncached — if caching is ever wanted, that is a new card, not this sweep)
3	#4288	packages/permissions/src — RoleDefinition.permissions (required field)	required and read by nothing in production; resolveRoles and every other consumer read only name/inherits (sole non-test hit is a test-comment documenting the state)	field removed (or demoted per the member card's discussion if remoteness of the type surface demands it — the PR states which and why); typing consumers compile clean

Sweep discipline (binding, per the pm-dispatch sweep rules):

1. All members hit the same criterion — zero-consumer dead surface, delete.
2. This table is the review checklist — reviewed per row, not per diff order.
3. Zero changes outside the N items; git diff --stat must map 1:1 to the rows (plus changeset).
4. Out-of-scope discoveries get their own cards (PD [WIP] Enhance every detail of the designer #10), never riders.
5. This card is the claim/dispatch object; members keep their queue state but are not individually dispatchable while this sweep is open (selection excludes them by this member list). PR carries Fixes #3775, Fixes #3778, Fixes #4288, and Fixes this card.

Member #3773 (RecordContextValue.loading/error) was considered and excluded: the premise has drifted — the context's memo now dep-lists both fields and the provider signature spreads all values, so zero-producer/zero-consumer needs re-measurement against current hosts before deletion is safe.

[os-zhuang]

Triage note (routing seat): #3773 is re-measured and promoted — recommend adding it as this sweep's fourth member.

The 14:47Z round excluded it pending re-measurement of its zero-consumer evidence. Re-measured this round on origin/main @ f046f88: RecordContextValue.loading/error have zero producers (RecordDetailView's provider call passes neither; PagePreview mirrors it) and zero consumers (no RecordContext ctx.loading/ctx.error read repo-wide; the one textual hit is the Metadata context). Only the memo dep list names them — dead wiring, deletes with the keys. Same judgment class as the three existing members. Full readings on #3773.

If this sweep is already claimed when you read this, leave the member list as-is and take #3773 as its own one-line card instead — no double entry.

CLAIM(sweep,四成员) — session session_017Qqyix2QcnpUC9XeYVDzx3(objectui whole-repo PM seat),dispatching now。Branch: claude/issue-4328-dead-surface-batch3。

按 triage 18:19Z 建议,#3773 增补为第四成员(其时本 sweep 未认领,符合"未认领则入列"的指示;成员卡上有本轮重测读数)。成员表:#3775(core 第二份 mergeViewsIntoObjects)、#3778(五处死 invalidate)、#4288(RoleDefinition.permissions 必填零读者——按成员卡讨论删除或降级,PR 说明取舍)、#3773(RecordContextValue.loading/error 零产零耗)。

sweep 纪律照卡片五条执行;两点补充:(1) #4288 的删除会让 #4287 立下、#4326/#4338 跟随的 permissions: [] 夹具惯例变成多余属性错——这些夹具行随删除一并清理,属于本行的爆炸半径而非越界;(2) 各成员的 grep 证据在你的分支点重测,不沿用 triage 的 ref(本日 main 走了 ~150 个 PR)。
