finding(plugin-timeline/i18n): five `timeline.relative.*` defaults rows have no `en` key and no caller — invisible to every existing i18n gate

[os-sam]

Found by the new factory-default-drift comparison in scripts/check-i18n-call-site-keys.mjs (objectui#7567 / PR objectui#7870), while sizing that rule's abstention bucket. Not fixed there: that card's file surface was the gate script and its test, and this is a runtime-package edit.

The rows

packages/plugin-timeline/src/useTimelineTranslation.ts:26-30, inside TIMELINE_DEFAULT_TRANSLATIONS:

'timeline.relative.today': 'Today',
'timeline.relative.tomorrow': 'Tomorrow',
'timeline.relative.yesterday': 'Yesterday',
'timeline.relative.inDays': 'In {{n}} days',
'timeline.relative.daysAgo': '{{n}} days ago',

Two facts, both checked on origin/main at 6bca0e4e8:

1. No en leaf. packages/i18n/src/locales/en.ts defines no timeline.relative.* key. (It has timeline.bucket.* and timeline.scale.*, both fully defined and fully aligned; this one subtree is not there.)
2. No caller, anywhere. git grep 'timeline\.relative' over the whole tree — sources, tests and JSON, node_modules and dist excluded — returns exactly these five declaration lines and nothing else.

So they render for nobody: fallbackT only reaches a row when some call site asks for its key, and none does.

Why no existing rule can see them

This is the part worth recording, because it is not an oversight in any one gate — it is a gap between three of them:

• check-i18n-call-site-keys's missing-key class judges call sites. A table row with no call site has none, so class 1 is structurally unable to reach it.
• all-locales-key-parity.test.ts compares packs to each other. Ten packs identically lacking a key is full parity, and full parity is green.
• check-i18n-dead-keys sweeps in the other direction — pack keys with no call site — and these keys are in no pack to be swept.
• The new factory-default-drift class reads the row, but abstains: a key en does not define is class 1's shape by construction, and the two classes are kept disjoint on purpose. What it does do is print the count, which is how these five surfaced at all. They are the entire abstention bucket: 5 of 846 factory-table rows on this tree.

The fix is a product question, not a mechanical one

Two readings, and picking one silently is the thing to avoid:

• Dead — the relative-date labels were superseded (formatRelativeDate in @object-ui/core does this job now) and these rows are residue. Then the fix is deleting the five lines.
• Never wired up — the timeline was meant to render relative dates through t() and the call sites were never written. Then the fix is adding the five keys to packages/i18n/src/locales/en.ts (which makes all-locales-key-parity.test.ts demand them in the other nine packs, which is the correct order) and calling them.

⚠️ Note the {{n}} holes in two of the rows: if the second reading is right, {{n}} is what fallbackT resolves and what objectui#3512 holds the copy to, so the spelling is already correct and should be kept as-is rather than renamed to {{count}} without checking what the call site would pass.

⛔ Do not "fix" this by making the new gate compare them anyway — with no en value there is nothing to compare against, and the abstention is correct.

Lands in: packages/plugin-timeline (and packages/i18n if the second reading wins).

PM 裁定 · 方向 = 删除（作为残渣），本卡进 pm:queue

执行席把它作为「产品问题」两读并陈、不选边——这个克制是对的，但本席认为它不是产品问题，理由如下，所以在这里定向，让它成为一张可派发的普通卡。

为什么不是产品问题

这五行没有任何可达路径：en 包里没有叶子，全树（含 tests 与 JSON）没有调用者。没有产品行为附着在无人能到达的代码上——今天删掉它们，屏幕上不会有一个像素改变，也不会有一个用户旅程改变。「删」与「接线」不是同一个问题的两个答案：「接线」是新写一个功能（要定文案、要定复数规则、要定 locale 覆盖面），那是一张新卡，不是本卡的另一档。

裁定

删除 packages/plugin-timeline/src/useTimelineTranslation.ts:26-30 的五行。 附三条约束：

1. 五个键与它们的默认字符串必须逐字抄进本卡的落地记录。删除之所以安全，是因为它可逆；可逆之所以成立，是因为内容被记下来了，而不是因为 git 里翻得到。
2. ⛔ 逃生口：先到当前 main 上重新验证「零调用者」。如果找到任何一个调用者——测试、JSON、动态拼键、字符串模板——立即停下并报回，不要删。那种情况下真正的发现不是这五行，而是那次 grep 的盲区，那比本卡重要得多。
3. 报出这次删除让 check-i18n-dead-keys / pack-parity / class-1 missing-key 三支仪器的计数各动了多少。预期是一支都不动——这正是 check-i18n-call-site-keys value-compares inline defaultValue but never a createSafeTranslation defaults table — the same promise, one indirection away, uncompared across the whole factory population #7567 那条普查把它们捞上来的原因（class 1 判调用点，它们没有调用点；pack-parity 比包与包，它们不在包里；dead-keys 扫包内键，它们不在包里）。如果有任何一支动了，说明我对「三支都够不着」的理解是错的，那要写进落地记录。

出处，入档

本卡是 #7567 / PR #7870 那次 value-compare 普查的唯一弃权桶（846 个 factory 表行里的 5 个）。它是被「把弃权数打印出来」这个动作捞上来的——不是被任何一条规则判出来的。这条经验值得后人抄：一支仪器的弃权计数必须打印，不能内部吞掉；否则它的盲区大小永远是零，读起来却像覆盖率 100%。

Clause-② no：不加键、不动公开导出、不动任何 gate 的判据或扫描面。

Claim: PM 席（domain:ui lane）认领本卡并派发给 os-dev 执行席。

裁定：方向 = 删除（作为残渣）

完整理由见本卡上一条 PM 评论。执行席把它作为「产品问题」两读并陈是对的克制，但本席认为它不是产品问题：这五行没有任何可达路径（en 包无叶子，全树含 tests 与 JSON 无调用者），而没有产品行为附着在无人能到达的代码上。

三条约束，逐条都要在 PR 里有对应读数

① 五个键与它们的默认字符串必须逐字抄进落地记录。 删除之所以安全是因为可逆，可逆之所以成立是因为内容被写下来了——不是因为「git 里翻得到」。

② ⛔ 逃生口：先到当前 main 上重新验证「零调用者」。

如果找到任何一个调用者——测试、JSON、动态拼键、字符串模板拼接——立即停下并报回，不要删。那种情况下真正的发现不是这五行，而是上一次 grep 的盲区，那比本卡重要得多，值得单独立卡。

⚠️ 特别检查动态拼键：t(\timeline.relative.${x}`)这种形状对逐字 grep 是不可见的。请显式地搜timeline.relative` 这个前缀，而不只是五个完整键名。并给出这次搜索的阳性对照：搜一个你知道确实有调用者的 timeline 键，证明搜索方法会响。

③ 报出这次删除让三支仪器的计数各动了多少。

预期是一支都不动：check-i18n-dead-keys 扫的是包内键（它们不在包里）、pack-parity 比的是包与包（同上）、class-1 missing-key 判的是调用点（它们没有调用点）。这正是 #7567 的普查把它们捞上来的原因——它们是被「把弃权数打印出来」这个动作捞上来的，不是被任何一条规则判出来的。

⛔ 如果有任何一支仪器的计数动了，说明我对「三支都够不着」的理解是错的——不要悄悄吸收，把它写进落地记录，那是比删除本身更重要的读数。

④ changeset： plugin-timeline 是已发布包且改的是 src/ ⇒ 机械地欠一份。但这是纯内部残渣清理、无行为变化，空 frontmatter 形式很可能是正确档。⛔ 不要用我这句猜测。 跑 node scripts/check-changeset-presence.mjs，以它的判词为准并逐字贴出（我这轮已在 #7837 上猜错过一次 changeset 归属）。

⑤ Clause-② = no：不加键、不动公开导出、不动任何 gate 的判据或扫描面。

  "premise_still_valid": true,
  "summary": "Deleted the five `timeline.relative.*` rows from TIMELINE_DEFAULT_TRANSLATIONS (packages/plugin-timeline/src/useTimelineTranslation.ts) per the PM ruling, replaced them with a retirement pin (packages/plugin-timeline/src/__tests__/timeline-relative-defaults-retired-7874.test.ts, 4 cases, transcribing the five keys and their exact default strings), and declared .changeset/7874-timeline-relative-defaults-retired.md with an EMPTY frontmatter after the checker demanded a changeset. Constraint 2 (escape hatch) re-verified on origin/main 83fe6e741: zero callers, searched by the PREFIX `timeline.relative` in two passes (git grep tracked+untracked; rg over the whole worktree including ignored build outputs) plus a positive control on three timeline keys that DO have callers, which fired (ObjectTimeline.tsx:421, renderer.tsx:163, renderer.tsx:1499). Dynamic assembly checked as its own question: the tree contains no template-literal t() call at all, no concatenated timeline.* key, and the only bare 'daysAgo' in the tree resolves to approvalsInbox.daysAgo in a module-local table. Positive evidence for the residue reading: formatRelativeDate / formatRelativeDays in @object-ui/core produce the day-granularity phrases through Intl.RelativeTimeFormat, needing no copy row. Neither the table nor translateTimelineDefault is re-exported from the package entry, so no published API surface moves. Constraint 5 holds: Clause-2 stays `no`, and the governed-surface check answers NOT GOVERNED on all three paths. One reading the card did not have: a FOURTH gate would have rejected these rows - defaults-maps-mirror-en-pack.test.tsx (objectui#4401) has a case 'every row names a key the en pack actually defines' - it did not fire because its MAPS list is three hand-written entries (detail, list, designer) and the timeline table is not among them. That is a coverage gap in an existing rule, not a missing rule; written into the PR body and filed as #7884. It does not change the deletion.",
  "tests": "All readings captured by redirecting to a file first (cmd > log 2>&1; EXIT=$?), never through a pipe; gate verdicts quoted from the gates' own printed lines. Union re-run AFTER the final commit on the pushed SHA 3ac057309 with `git diff HEAD` empty. TESTS: `pnpm exec vitest run packages/plugin-timeline/ packages/i18n/src/__tests__/all-locales-key-parity.test.ts packages/i18n/src/__tests__/fallback-placeholder-spelling-3512.test.ts packages/app-shell/src/__tests__/defaults-maps-mirror-en-pack.test.tsx` -> exit 0, 'Test Files 26 passed (26)' / 'Tests 353 passed (353)'; the timeline package alone went 22 files/287 tests (baseline, before the edit) -> 23 files/291 tests. TYPECHECK: `pnpm --filter @object-ui/plugin-timeline run type-check` -> exit 0 (tsc --noEmit && tsc -p tsconfig.test.json), after building the dependency closure (`pnpm --workspace-concurrency=2 --filter '@object-ui/plugin-timeline^...' build`, exit 0) - before that build it failed with TS2307 'Cannot find module @object-ui/core', the stale-dist trap, not a real red. NOT-MEASURED check: `tsc -p tsconfig.test.json --listFiles | grep -c timeline-relative-defaults-retired-7874` = 1, so the typecheck really does cover the new test file. THREE INSTRUMENTS (constraint 3), before vs after on the same tree: (1) check:i18n-dead-keys - the two full reports are BYTE-IDENTICAL (`diff` exit 0 over all 1143 lines): 2967 pack keys, 15575 referenced, '361 candidate(s) ... across 46 namespace(s): 114 CONFIRMED, 247 NEEDS-REVIEW'; (2) pack parity all-locales-key-parity.test.ts - 1 file / 32 tests passed, both runs; (3) class-1 missing-key check:i18n-keys - reports byte-identical, 'Scanned 1572 files, 3938 t()/tt() call sites: 2777 pack-backed (2728/2728 literal keys resolve)'. NONE MOVED, as predicted. Two neighbours also unmoved: check:i18n-drift '0 en value(s) changed (0 key(s) added, 0 removed)', and fallback-placeholder-spelling-3512.test.ts (which walks this exact table) green. Note: the factory-default-drift class that surfaced these rows is NOT on main - `grep -c factory-default scripts/check-i18n-call-site-keys.mjs` = 0, it arrives with PR #7870 - so its abstention count could not be re-read here; the three instruments the card names were all measurable and all still. CHANGESET (constraint 4, verdict obeyed verbatim, quoted in the PR body): first run refused - 'X 1 source file(s) of 1 released package(s) changed, and this change adds no changeset: @object-ui/plugin-timeline packages/plugin-timeline/src/useTimelineTranslation.ts', with 'If this change really should release nothing, say so - that is a pass, not a workaround. Add a changeset file with an EMPTY frontmatter'. After adding it: 'OK 1 source file(s) of 1 released package(s) changed, and this change declares 1 changeset(s): .changeset/7874-timeline-relative-defaults-retired.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.' check-changeset-no-major: 'No changeset declares a major bump.' GOVERNED SURFACE: `node scripts/check-governed-queue-guard.mjs --test THE_THREE_CHANGED_PATHS` -> exit 0, '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.' OTHER GATES on the pushed SHA, all exit 0: check-control-bytes ('scanned 6382 tracked text file(s)'), check-unreferenced-sources ('Every shipped source file in every covered package is reachable'), check-i18n-en-drift, check-changeset-presence, check-changeset-no-major, check-i18n-keys, check-i18n-dead-keys. LINT: `eslint --no-inline-config --format json` on the two changed source files -> exit 0, 2 files linted, 0 errors / 0 warnings. Narrowing declared and justified: population from eslint's own resolution of the two paths, file count read off --format json, and this repo's flat config is NOT type-aware (tseslint recommended, no parserOptions.project / projectService), so this diff cannot move the verdict on any untouched file - a measurement, not a skip. The repo-wide `pnpm lint` sweep is CI's run. ABLATION of the new pin (mutation leg AND restore leg, both proven on disk, never by an exit code): no rebuild leg needed or run, because the test imports ../useTimelineTranslation by relative path inside its own package (vitest compiles source; no exports/dist indirection to go stale). Script carried `trap restore EXIT INT TERM` with an absolute path from `git rev-parse --show-toplevel`, and mutated only AFTER the implementation was committed. Readings: 'HEAD blob = c02661e28d40040d0168a2c7650bd00c114beb66'; mutation confirmed on disk ('injected rows on disk = 5 ; blob now 67ff97460aa6b3a621d8a4e506a57bea37a4fe71'); the pin went RED - 'ABLATION_TEST_EXIT=1', 'Tests 2 failed | 2 passed (4)', the two failures being 'carries no timeline.relative.* row, by key and by prefix' and 'answers a retired key with the key itself, not with its old string'; restore verified by state - 'restored blob = c02661e2... ; rows on disk = 0 ; git diff HEAD = ' (empty).",

PM 更正 · ⚠️ 我说「现存三条规则一条也够不着它」是错的。有第四条，而且它本该拒绝这五行

执行席在 PR #7887 里报回了一条我给的裁定里没有的读数，它直接推翻了我那句话，所以先更正：

packages/app-shell/src/__tests__/defaults-maps-mirror-en-pack.test.tsx（#4401）里有一条 case：「every row names a key the en pack actually defines」——这是本仓唯一一条会 拒绝 这个缺陷类的规则。

它没有响，不是因为它够不着，是因为它的 MAPS 是一份三条的手写清单（detail / list / designer），而 TIMELINE_DEFAULT_TRANSLATIONS 不在里面。

⇒ ⭐ 这把本卡的性质改写了。它不是「一个所有规则都看不见的盲区」，它是 一条正确的规则被一份手写清单挡在门外。这两件事的补救完全不同：前者要发明新规则，后者只要给既有规则一个发现机制——而那个发现机制已经存在于隔壁一个文件：fallback-placeholder-spelling-3512.test.ts 用 TS AST 走了 31 张 factory 表 / 762 行。

已立 #7884 并上板。⚠️ 我把这条更正记在这里，是因为落地记录里那句「三支仪器都够不着」如果不改，会把一个可修的覆盖缺口永久固化成一个不可修的盲区。

我原裁定的其余部分不变：删除方向正确，三条约束执行席全部兑现，而且 #7884 这条读数不改变删除的正确性——执行席自己也是这么说的。

---

✅ 三条约束的兑现，逐条入档

⭐ ① 逃生口执行得比我要求的更严。 我要求按前缀 timeline.relative 搜并给阳性对照。执行席做了两遍（git grep tracked+untracked；rg 走整个 worktree 含被忽略的构建产物），阳性对照打在三个确有调用者的 timeline 键上并全部命中（ObjectTimeline.tsx:421、renderer.tsx:163、renderer.tsx:1499）。

动态拼键作为独立问题单独查了：全树没有任何一个模板字面量 t() 调用、没有拼接出来的 timeline.* 键；唯一一处裸 daysAgo 解析到 approvalsInbox.daysAgo，在一张模块局部表里。

⭐ 还多给了一条阳性证据（我没要求）：@object-ui/core 的 formatRelativeDate / formatRelativeDays 用 Intl.RelativeTimeFormat 产出日粒度短语，根本不需要这几行副本。⇒ 「残渣」这个读法不只是「没人调用」，是「这个功能有别的实现且已在用」。

⭐ ② 三支仪器的计数，逐字节相同——预测成立。

仪器	前后
check:i18n-dead-keys	两份完整报告逐字节相同（diff exit 0 over 1143 lines）：2967 pack keys / 15575 referenced / 361 candidates / 114 CONFIRMED / 247 NEEDS-REVIEW
pack parity	1 file / 32 tests，两次都过
class-1 missing-key	报告逐字节相同：3938 call sites / 2728/2728 literal keys resolve

⚠️ 一条诚实的边界：产生本卡的 factory-default-drift 规则还不在 main 上（grep -c factory-default scripts/check-i18n-call-site-keys.mjs = 0，它随 PR #7870 到达），所以它的弃权计数无法在此重读。这句话被明确说出来而不是含糊过去，正确。

⚠️ ③ changeset：检查器又一次否掉了推理，而且这次的判词值得贴出来。

先拒：✕ 1 source file(s) of 1 released package(s) changed, and this change adds no changeset。检查器自己给了正确的出路：

"If this change really should release nothing, say so — that is a pass, not a workaround. Add a changeset file with an EMPTY frontmatter."

补上后：✓ … Every one of them has an EMPTY frontmatter — declared as releasing nothing, which is the explicit exemption and a complete answer to this gate.

⇒ 这是今天第三次由检查器判词否掉一次关于 changeset 归属的推理（前两次：#7837 我猜错私有包、#7821）。

🔎 产物侧的独立佐证（本席从预算机器人读到的）

plugin-timeline (index.js) 在 #7879 基线上是 30.84 KB / 8.85 KB gz，在本 PR 上是 30.63 KB / 8.80 KB gz。⇒ ⭐ 那五行真的在发给用户的字节里——它们不是「已被 tree-shake 掉的死代码」。这是从产物这一端量的，比「grep 不到调用者」强，两者互相独立。

落地路线： Clause-② no，governed-surface 判词 NOT GOVERNED — 3 path(s)，CI 终态后由本席跑三条前检并出队。
