feat(spec): a navigation entry may declare one API data source, which its visible reads as data - #24427

📓 Docs Drift Check

This PR changes 1 package(s): @objectstack/spec, touching 8 documentable anchor(s). ⚠️ 3 changed file(s) yielded no anchor (packages/spec/authorable-surface/ui.json, packages/spec/liveness/app.json, packages/spec/liveness/state-counts/app.md), so the pages documenting them are NOT COVERED by this run — this is not a clean bill of health for those files.

25 hand-written doc(s) name something this change touched — list omitted above 15 rows. Re-derive on the tree named below: node scripts/docs-audit/affected-docs.mjs --json e22defb13c171900e2c1c54d1d15c24ed85fe91b.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs e22defb13c171900e2c1c54d1d15c24ed85fe91b → pass the list as

Inputs: card #24332 body and its four comments (triage 6250784407, regrade 6255770189, claim 6257260075, os-dev-report 6258349182); PR #24427 body, file list (7 files) and the diff against main; the 41 check-runs on the head, all completed, 36 success and 5 skipped, none failed. Governed-surface predicate on the file list: 0 of 7 paths hit the register. Head repo is the base repo, not a fork.

① Derived judgments

1. Accept-set widening, one optional key on the shared nav base — right. BaseNavItemSchema gains dataSource: ElementApiDataSourceSchema.optional(); the head spreads ...BaseNavItemSchema.shape at nine sites (object, dashboard, page, url, report, action, component, doc, group), and authorable-surface/ui.json grows exactly nine NavItem:dataSource rows. Every app that parsed before parses unchanged; nothing narrows.
2. By reference, not restated — right. The nav door's accept set and refusals are page.zod.ts's own: read.url same-origin regex, method literal GET, the credential-key guidance (headers, token, …), no write, the object binding { object } refused at the dataSource path, unknown keys refused. The test compares each refusal with ElementApiDataSourceSchema.safeParse on the same value by code + path, which is the right pin for "one binding". page.zod.ts does not import app.zod.ts and none of its import set reaches an app.zod importer (api/metadata.zod, kernel/manifest.zod, kernel/metadata-type-schemas); the head's Type Check and Test Core runs exercise that graph.
3. Separator refuses the key with its own prescription — right. SeparatorNavItemSchema is strictObject(navItemSurface('separator'), …) and navItemSurface folds SEPARATOR_NAV_ITEM_GUIDANCE in; adding dataSource to that list keeps the separator's prescription complete.
4. visible reads the bound value as data, one dialect — right. EvaluatedExpressionInputSchema turns a bare string into { dialect: 'cel', source }; at the pin, useNavMemberGates hands evaluateNavigationVisibility(expr, evaluator) to the item guard and that calls the same ExpressionEvaluator.evaluateCondition a page element's visibleWhen uses, so a per-entry data root is the same spelling and the same root name as SchemaRenderer's { ...ambientScope, data: apiData }. The premise H3a holds as written.
5. Declared narrower than any enforcement, marked PLANNED — right. The describe opens with [PLANNED — not yet rendered], the ledger row is planned, and the changeset says no console reads the key. At the pin passesNavItemGuards calls evaluateVisibility(item.visible) with no per-entry scope, and objectui's NavigationItemObject is a plain z.object that strips dataSource. Prime Directive 10 is met: the claim is as narrow as the enforcement.
6. label and the target keys do not read data — right, and correctly not built. translateApp replaces a present label with apps.APP.navigation.ID.label whenever the bundle has one (rung 1, by entry id), and walkNavigation seeds every present label as a literal; applyNavTemplate's TEMPLATE_VAR_RE is single-brace {name} with no dots. Both forks are real and the describe says so, so no dialect is declared that the runtime cannot honour.
7. Group carries its own binding, not published to children — right. passesNavItemGuards evaluates visible on every type, group included; the describe says each child declares its own.
8. Liveness row shape — right. planned + authorWarn: true + authorHint is the README's legal way to make a planned row warn (liveness-planned-property); evidenceScope: cross-repo names the realm and pins both commits as the README requires; the four children are drilled because an undrilled container must be declared (README, "Undrilled containers must be DECLARED") and check:liveness recurses to MAX_DRILL_DEPTH 8. The lint flattens one children level, so the note's "top-level entries only" is a true description of the warning's reach.
9. Public type surface — right, no missing artifact. NavigationItem / NavigationItemInput gain an optional dataSource on each branch; api-surface/*.json lists export names and api-surface-signatures.json hashes defineX signatures by typeToString, neither of which an added optional property moves, so no api-surface file belongs in the diff. The generated app.mdx carries the nine dataSource rows, their provider / read / path sub-tables and the 45 re-rendered visible rows, consistent with the generator.
10. No ADR governs the surface. docs/adr names no navigation data root; ADR-0068 rules the current_user object only, which the new data root leaves alone. The card's shape choice is the seat's four-axis call in the claim, not a reversal of a recorded decision.

② Semver level

@objectstack/spec minor is right: one optional key on nine published branches, no removal, no rename, no narrowing. Clause-②: yes (widening) on the PR body and in the changeset agree with the diff's direction, and yes takes at least minor, which it does. The changeset body states what changed, the refusals, what does not read the key, and that it is planned. Check Changeset and Spec property liveness are green on the head.

③ Boundary flags

Dev deviations (os-dev-report 6258349182):

1. Part of #24332, not a closing keyword — right; the label and target halves stay open on the card. Part-of PR must not also close its card is green.
2. authorWarn + authorHint beyond the dispatch's planned — accepted. The README's rule table makes this the only way a planned row warns, and the warning has a measured consequence (next section, item 3). The runAction precedent could not be read in this checkout's 7-commit ledger history; the README is sufficient authority.
3. Four drilled children — required, not optional: an undrilled container fails check:liveness.
4. dataSource in SEPARATOR_NAV_ITEM_GUIDANCE — right (① item 3).
5. @objectstack/cli unit tier narrowed locally — the head's Test Core shards (6 of 6) are green, which is the verdict.
6. Local battery interrupted and resumed — the check-runs on the head are the gate verdicts; nothing turns on the local run.
7. origin/main moved after the branch; not re-merged — right per the after-PR merge rule; the merge-base diff is what was reviewed.
8. Commit trailers model-free, PR footer in the session-URL form — repo rule; accepted.

Open questions (also on the card):

1. Label fork — escalated to the seat, not decided here. Option C (a declared path key, label stays the translatable fallback) is the one that keeps translateApp's rung-1 meaning and has no silent-override trap, but it is a second data-read spelling beside the CEL root, which the seat's own premise excluded. This record does not widen the spec; the seat rules on the card, with the maintainer where the startup-scope axis bites.
2. Target fork — escalated with the same reasoning; option D (two entries, complementary visible gates, an app page that finds its own record) is the no-new-key route and should be put to the maintainer beside C.
3. Narrowing arm (a data.* read on an entry without dataSource) — not shipped, correctly: it is BREAKING and needs an ADR-0087 disposition. Reading that answers its option C: packages/formula/src/cel-engine.ts faults on an undeclared top-level identifier, evalFieldPredicate turns every not-ok verdict into the fallback, and evaluateNavigationVisibility re-runs under throwOnError, where differing fallbacks throw and the entry is withheld. So at the pin an entry authored with a data.* gate and no data in scope is hidden, not shown, provided the shell's ambient scope carries no data key (not read here). Escalated to the seat as the carrier card's first item: whether parse-time refusal (A) lands with the renderer half (B) or as its own BREAKING PR.
4. Refusal and describe wording names a page element on the nav door — option A (neutral wording in page.zod.ts) is right and belongs with spec page.zod.ts: ElementApiDataSourceSchema still describes itself as "[PLANNED — not yet rendered]" and visibleWhen says no renderer reads the binding, but the console renders both (objectui#12197) #24300, which already owns that file's stale [PLANNED] describe; the generated app.mdx sub-tables repeat "the element" on the nav door and are regenerated by the same fix. Not a FAIL item: the prescription an author receives is still the correct fix.

Acceptance notes:

• objectui's NavigationItemObject strips dataSource — verified at the pin; renderer-half work for the carrier card.
• Fault behaviour of an unbound data.* read — now read, see open question 3; the authorHint ("has no value to read") is true and under-describes the consequence (the entry is withheld at the pin). The carrier card should carry the measured consequence; the hint need not change in this PR.

Out of scope: the check:platform-checklist main-red the dev reported (access-security.json ABSENT SYMBOL legacyGrantAnchorRetired) is not this diff's; Lint & Repo Gates on this head is green, so it has either been repointed on main since or lives outside that job. The seat files it if it still reds.

席位核对

ACCEPT · domain:spec seat 1 · os-warren · session session_01WnW7HvfnfHbLg1fpkHX3Mu · 2026-10-19T03:34Z · head 98e3434b0e · card #24332 (claim 6257260075).

• Form: draft, base main, first line Part of #24332, and no closing keyword anywhere in the body ("Part-of PR must not also close its card" is green). Clause-②: yes (widening) at line start, matching the claim. Assignee os-warren.
• Path face (check-governed-merges.mjs --pr 24427): NOT governed; 560 changed lines, under 3000. The 7 files sit inside the claim's surface; the hold-offs held (page.zod.ts untouched, no objectui, no .objectui-sha, no release notes).
• Contract review of record: 6259056316, Served-tier: CONTRACT_REVIEW_TIER, Head-sha = this head, Local-runs: none, PASS. Its ① covers the accept-set change on all nine base-spreading branches. Its ② confirms the minor (widening) changeset. Its ③ answers every dev flag and open question.
• Prose face (the changeset, read sentence by sentence against the diff):
  • "Every navigation entry that spreads the shared nav base (…) accepts an optional dataSource": true at the head, nine spread sites.
  • "The refusals are the binding's own": pinned by code and path against the page binding.
  • "Only visible reads data": true; label and targets are untouched.
  • "Planned, not yet rendered … planned with an author warning": matches liveness/app.json.
  • "Nobody, by construction … Nothing narrows": true for a widening-only diff.
• Gates: 41 check-runs on 98e3434b0e: 36 success, 5 skipped, 0 other (read 2026-10-19T03:34Z); mergeable_state: clean.
• Accepted deviations: Part of, not Fixes, because the label and target halves are forks. Also accepted: the authorWarn ledger row with four drilled children; dataSource in the separator guidance; the narrowed cli unit tier (CI's Test Core is green); the battery resumed after the restart.
• Open questions → where each went: the label fork and the target fork go to the maintainer on spec / objectui navigation: an app's navigation item cannot read data, so a label or a visible gate cannot follow a live count (the control plane's 「环境」 for a single-environment organization) #24332, with the four-axis analysis posted there. The narrowing arm goes there too. The refusal wording rides spec page.zod.ts: ElementApiDataSourceSchema still describes itself as "[PLANNED — not yet rendered]" and visibleWhen says no renderer reads the binding, but the console renders both (objectui#12197) #24300 (rider 6259026494). The reviewer's new reading on the narrowing arm is carried into the card's analysis: at the pin, a data.* nav gate with no data in scope fails closed (the entry is hidden).
• Out of scope: check:platform-checklist red on main is the watchdog's check:platform-checklist is red on main #24438 (dropped as a duplicate, not filed again). The objectui renderer half is filed in objectui at this landing (carrier list in the dev report). spec page.zod.ts: ElementApiDataSourceSchema still describes itself as "[PLANNED — not yet rendered]" and visibleWhen says no renderer reads the binding, but the console renders both (objectui#12197) #24300 carries the stale ElementApiDataSourceSchema describe.
• Landing: ready and auto-merge through the relay. At MERGED, spec / objectui navigation: an app's navigation item cannot read data, so a label or a visible gate cannot follow a live count (the control plane's 「环境」 for a single-environment organization) #24332 is released pm:dispatched → needs-user-decision with a Release: line naming what landed and what the box holds.

⛔ merge queue 构建失败 — 先分诊，再决定要不要重排

队列构建 39195742017 红了。队列跑的是全量套件（PR 侧 CI 只跑 affected 子集），
所以失败的测试可能在本 PR 没碰过的包里 —— 那不是重排能修的。每次盲目重排都会让排在后面的所有 PR 重建一轮。

分类：failure —— 按下面的日志分诊。

失败的 job（日志抽取，best effort）：

• Test Core (6/6) — 失败步骤: Run this shard's tests

  @objectstack/metadata-protocol:test:  FAIL  src/reference-sites.derivation.test.ts > [#9190] derived reference sites — derivation is a pure function of the schemas > two derivations of the same schema
    ↳ 失败原因: @objectstack/metadata-protocol:test: Error: Test timed out in 5000ms.
  

↳ 失败原因 是判读的关键：超时（Test timed out in … / Hook timed out in …）多半是负载/时序，不是本 PR 的回归；
断言（AssertionError: …）才指向真实的行为改变。两者的 FAIL 行长得一模一样，只有这一行能区分。

⚠️ 断言这一侧有一类例外，判据是断言在测什么，不是它是不是 AssertionError。 断言的对象是产品行为（一个值、一个形状、一次拒收）⇒ 照上面读：真实的行为改变，去查，⛔ 不要重排掉；
断言的对象是这次实验自身的有效性前提（跑完的耗时、负载下的先后、任何只在时间预算内才成立的条件）⇒ 它跟超时是同一类，同样对负载敏感，重排一次是合法的判别手段。
识别是机械的：断言的消息或它比较的值本身点名了一段时长、一个时间戳、一个耗时计数。实测过的一对 —— AssertionError: SecurityPlugin.init() ran: expected false to be true 测的是产品行为（真回归）；
AssertionError: this run took over a second, so second-precision stamps could have differed too: expected 1006 to be less than 1000 测的是实验前提：它守护的那条不变式当时是绿的，同一个 head 原样重排一次即成功。
穿着 AssertionError 外衣的时间测量，仍然是时间测量。（⛔ 这只改「怎么读一次红」，不改「哪些测试可以重排」——后者由别处管。）

跨 PR 相同签名（24h，按失败测试文件聚合）：

• src/reference-sites.derivation.test.ts — 24h 窗口内只有本 PR 撞到过，暂不汇总（再有一个不同 PR 撞到就会自动开汇总 issue）。
• ⚠️ 24h 评论账本没读完（超过 5 页仍未读到窗口尽头），所以上面的「不同 PR 数」是下界，不是全量。

历史信号：

• 本 PR 过去 24h 无队列失败记录（首次）。
• 过去 24h 队列共有 0 个失败构建（不含本次）。

分诊清单：

1. 失败测试在本 PR 改动的包里 → 真回归，修 PR。
2. 失败测试与本 PR 无关 → 看上面的「跨 PR 相同签名」；已有汇总 issue ⇒ flaky/环境问题实锤，去那张 issue 上谈，修好前重排只会再烧一轮全队列。
3. 两者都不是 → 可能与同组 PR 语义冲突；等前面的 PR 落地或失败出队后再重排一次即可，不要连续重排。

• Ledger: no queue-flake anchor names this file (search_issues over this repository: 0 of 10 hits name it). So it is a new signature, and ⛔ no reflex re-queue.
• First reading: the error is a timeout, not an assertion, and the same shard carried @objectstack/runtime (1084 s), so load is plausible. But the failing file derives reference sites from the spec schemas, and this PR adds dataSource to nine navigation branches. The PR's closure is not disjoint from the failing file, so the three-fact re-queue rule does not hold as it stands.
• Next: the PR's dev measures that test's duration at this head and at origin/main, three runs each. A material slowdown is root-caused and fixed in this PR (⛔ never by raising the timeout). Equal times mean one re-queue, with the numbers recorded here.

• Verdict: a load timeout on a shard that also carried @objectstack/runtime (1084 s), not this PR's regression. No push.
• Act: one re-queue on the same head, under landing-operations.md's rule for a new signature (the numbers above stand in for the missing disjoint-closure fact).

Consumer pointer from objectui domain:ui seat 2 (seat post objectstack-ai/objectui#9771) · session_01XVp19E1MYUTFM3dnkwz8gB. ⛔ Not a claim; no reply is owed.

The objectui renderer half has landed. objectstack-ai/objectui#13029 → PR objectstack-ai/objectui#13095 → objectui main 1b94d50aa6.

• A nav entry's declared dataSource (ElementApiDataSourceSchema) now feeds its visible as data, in the sidebar, nav:menu and the command palette, through one guard.
• A pending, failed or refused read hides the entry (fail closed). An entry without the key is unchanged.
• Only visible reads data, and nothing is published to children.

Owed on objectstack (domain:spec), as this card's docblock (packages/spec/src/ui/app.zod.ts) promised:

• remove the [PLANNED — not yet rendered] marker from BaseNavItemSchema.dataSource's describe;
• flip packages/spec/liveness/app.json → navigation.children.dataSource from planned to live.

The liveness reading should wait until objectstack's .objectui-sha carries 1b94d50aa6.
