Part of #25921

Clause-②: no
Metadata-protocol: none

维护者速读

• 改了什么:删除 @object-ui/collaboration 里的 createPresenceUpdater 和 @object-ui/mobile 里的 requestBackgroundSync 两个函数体,共 50 行。
• 为什么改:上一个 PR 已把这两个名字移出包入口,仓库内再无任何读取者,留着只是死代码。
• 风险与回滚:无公开面变化,两个包都只有一个 . 入口,外部无法导入;回滚即 revert 这一个提交。
• 先看:ui/packages/collaboration/src/usePresence.ts 末尾、ui/packages/mobile/src/serviceWorkerSource.ts 末尾(都是文件尾部整段删除)。
• 两分钟验证:git grep -nw -e createPresenceUpdater -e requestBackgroundSync -- . ':!**/CHANGELOG.md' 只应命中 .changeset/ 里 retire the zero-consumer surface: nine dead modules (2,211 LOC), plugin-ai, runner's publish flag, test-only reset helpers on public barrels, the providers trio, 122 dead i18n keys, root orphans #25921 的三个 changeset(本 PR 新增的一个,加上 PR refactor(ui)!: retire zero-consumer exports from @object-ui/collaboration and @object-ui/mobile #28385 的两个),源码零命中。
• 需要你做的:无,席位落地。

What changes

Deletes the module-local function createPresenceUpdater (usePresence.ts) and requestBackgroundSync (serviceWorkerSource.ts). No imports or types became unused; no test exercised either function (none found by git grep -w). Net 50 deletions plus one patch changeset.

Changeset vs skip-changeset: both packages compile with tsc and ship dist (files[]), so dist/usePresence.js and dist/serviceWorkerSource.js change bytes; a patch changeset is added and no skip-changeset label. It is not a public-surface change: the single . export of each package already dropped both names.

Tests

• pnpm --filter @object-ui/collaboration run type-check exit 0; pnpm --dir ui exec vitest run packages/collaboration/ 7 files / 83 tests pass.
• pnpm --filter @object-ui/mobile run type-check exit 0; pnpm --dir ui exec vitest run packages/mobile/ 6 files / 50 tests pass.
• Dependency closure built first (@object-ui/collaboration^..., @object-ui/mobile^...).

Acceptance notes

• Premise re-measured on origin/main 125ad06: git grep -nw over the whole tree (examples, packages/console, skills, content/docs, READMEs) finds each name only at its definition plus CHANGELOG history.
• pnpm --dir ui exec vitest run scripts/ exits 1 on one test (unit-registry-absence-collision) because @objectstack/client has no built entry in this worktree (not built; outside the two packages' closure); it reads packages/app-shell/..., not the files touched here. Reported as NOT MEASURED for that family; CI builds it.

Verification

Derived gates at bec3be1 (all exit 0 except the one above)

node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack run in full, including node scripts/check-sdui-manifest.mjs (0) and pnpm check:published-files (0), check:nul-bytes (0), check:test-source-alias (0), check:undeclared-dep-imports (0).

席位核对

1. Shape: three files (+11 / −50): the trailing createPresenceUpdater block in ui/packages/collaboration/src/usePresence.ts, the trailing requestBackgroundSync block in ui/packages/mobile/src/serviceWorkerSource.ts, and one patch changeset for both packages. Inside claim 6542651046. Part of #25921, no closing keyword. Not governed, 61 lines (check-governed-merges --pr 28402: NOT governed).
2. Premise, measured: on origin/main after 8c8c5b52 each name occurs only at its own definition plus CHANGELOG / .changeset/ history; neither package entry (single . export) carries it since PR refactor(ui)!: retire zero-consumer exports from @object-ui/collaboration and @object-ui/mobile #28385. So no contract face: Clause-②: no, no published name moves, no contract review owed.
3. Gates (check-runs on this head): 59 runs, 46 success, 13 skipped, 0 other; Lint & Repo Gates, TypeScript Type Check and Check Changeset success.
4. Deviations accepted: the dev's local vitest run scripts/ (ui) family was NOT MEASURED (an unbuilt @objectstack/client in the worktree, outside the touched files); CI's shards on this head are the reading of record. The PR body's two-minute check line was corrected by the seat (it now names all three retire the zero-consumer surface: nine dead modules (2,211 LOC), plugin-ai, runner's publish flag, test-only reset helpers on public barrels, the providers trio, 122 dead i18n keys, root orphans #25921 changesets as the only remaining hits).
5. Out of scope: none new. The card keeps its remaining items (6542309053).
6. Changeset, read sentence by sentence: patch for both packages, says neither name is reachable from the entry and that only the compiled module bytes change; true against the diff. A changeset rather than skip-changeset because the published dist bytes change; accepted.
7. Landing: pr_ready + automerge_enable through the relay, MERGED confirmed, then the partial-landing release of retire the zero-consumer surface: nine dead modules (2,211 LOC), plugin-ai, runner's publish flag, test-only reset helpers on public barrels, the providers trio, 122 dead i18n keys, root orphans #25921 back to pm:queue.
