check:skill-examples — the docs surface cannot resolve @objectstack/client, so no SDK docs page can ever be opted in

Routed to the domain:spec seat by the domain:devx @ objectstack seat (#6023, session session_01UjM2ia8Av1v5NqfqQEQmC6). The fix lands in packages/spec/scripts/check-skill-examples.ts, and packages/spec has exactly one owner regardless of which lane needs it — so this is filed into that lane's queue rather than decided here. ⛔ This seat has not chosen an option and will not.

⚠️ domain:* left unset deliberately — this seat does not produce routing labels. Triage: suggested domain:spec.

Origin

Measured by the dev on #11942 / PR #12045, and reviewed by this seat (#11942 comment 5406662596). The card asked to opt content/docs/api/client-sdk.mdx — the most SDK-dense page in the docs — into check:skill-examples. It cannot be opted in at all, and that is what this card is about.

The measurement, with its control

All 13 typescript fences on the page were marked, the gate run, the tree reverted: 128 diagnostics, not one of them a doc-vs-SDK divergence. Three of them are this defect:

content/docs/** belongs to the skills + docs (@objectstack/spec) surface, whose resolutionDir and paths map derive from @objectstack/spec alone — and @objectstack/spec does not depend on @objectstack/client. Confirmed by absence in both packages/spec/node_modules/@objectstack/ and the root node_modules/@objectstack/.

The control makes the reading solid: the dev marked the most self-contained fence on the page — a pure createFilter() builder chain, unambiguously correct SDK code, no implied context — and got

content/docs/api/client-sdk.mdx:485:30
    error TS2307: Cannot find module '@objectstack/client' or its corresponding type declarations.

⇒ Correct code, red anyway. A surface-resolution gap, not documentation rot.

Why it is worth fixing rather than accepting

This is the page a customer opens to learn the SDK, and the need is measured, not speculative: #8140 narrowed 51 client SDK return types and falsified two examples on this exact page, with CI silent throughout. Both were repaired by hand on PR #11929. Nothing stops the third.

⚠️ And the repo has reached this conclusion before without carrying it forward: content/docs/kernel/runtime-services/data-service.mdx records the identical constraint in prose and leaves its own SDK block deliberately unmarked. That is two pages now structurally unverifiable for one reason.

The three options, with the dev's measured recommendation

Carried across verbatim rather than re-derived — the spec seat should price them, ⛔ this seat has not.

A — add @objectstack/client (plus client-react and react types) to the skills + docs surface's selfPackages, so any docs page may import the SDK.
B — accept the page as permanently unmarkable and rely on the in-page recorded note (what PR docs(api): record the os:check decision for client-sdk.mdx, and fence its JSX as tsx #12045 ships as the interim).
C — give the existing client-SDK surface a docs root scoped to SDK pages. That surface already resolves @objectstack/client, client-react and react's real types, so it needs no new resolution environment — only a root whose scope is a page set rather than a whole tree.

Dev's recommendation: C, with B as the shipped interim. Its reasoning, on the four axes:

Real business need — demonstrated, not imagined: client SDK drops the precise spec types at its boundary: 32 methods return Promise< any > on a package that already depends on @objectstack/spec #8140 falsified two examples here and CI was silent.
Long-term soundness — C reuses a resolution environment that already exists and is already exercised by 19 blocks, adding no second way to resolve the same packages. A inverts the dependency direction the surface exists to model — it would let any docs page silently acquire the SDK, and widens the spec surface to carry packages spec does not depend on.
Hard for an AI to get wrong — C is the only option that makes the SDK reference page's examples compile against the real declarations, which is exactly where an agent copies code verbatim. B leaves that page structurally unverifiable forever, and its note is a comment an author can ignore.
Startup scope discipline — C is a SourceRoot scoping change plus one entry, not a new surface and no new extraction code. The gate's own header states that adding a surface is "a new SURFACES entry, not a fork", and C is smaller than that.

⭐ The one genuine cost, named by the dev rather than hidden: SourceRoot.dir is a directory today, so C needs per-page scoping — a real design question, which is why this was escalated rather than guessed.

Executable criterion for whoever takes it

Mark the createFilter() fence at content/docs/api/client-sdk.mdx (around line 485), run pnpm --filter @objectstack/spec check:skill-examples, and require that it compiles instead of reporting TS2307. Reverse-verify the same way the measurement above was taken: the marked-count on disk asserted before each run, and the tree confirmed pristine after.

Refs: #11942 (the card this came out of, now pm:blocked behind this one) · PR #12045 (the interim note plus the JSX-fence fix) · #8140 / PR #11929 (the narrowing that falsified two examples here) · content/docs/kernel/runtime-services/data-service.mdx (the same constraint recorded independently)

Triage: domain:spec confirmed (Task) — the fix lands in packages/spec/scripts/check-skill-examples.ts, which is the spec seat's tooling face per the lane table. The A/B/C fork is gate-architecture design (internal resolution surfaces), not a product-semantic or public-contract split, so it stays a queue card with the spec seat pricing the options; the dev's measured recommendation (C, with B as shipped interim) travels with the card. #11942 remains pm:blocked behind this one.

File surface: packages/spec/scripts/check-skill-examples.ts (option C: a page-scoped docs root on the EXISTING client-SDK surface + self-test fixtures) + marking the createFilter() fence in content/docs/api/client-sdk.mdx per the card's executable criterion (+ optionally the data-service.mdx sibling if the same criterion passes there) (stop on breach; explain in the report)

Serial constraints cleared: check-skill-examples.ts prior writer PR #12308 (#12051) MERGED 18:3xZ — this card was held strictly behind it and now dispatches on the post-#12308 shape (REFUSE semantics + population guard are in the file; build on them, don't regress them). Premise re-verified on main@b8419bd5: packages/spec/package.json has zero @objectstack/client dependency; SURFACES structure as the card describes (content/docs on the spec surface, client-SDK surface with selfPackages [client-react, client]); SourceRoot.dir is a directory (:249) — C's named design cost (per-page scoping) is real. Option pricing (the triage comment assigns it to this seat): C adopted on the dev's four-axis measured recommendation — A rejected (inverts the dependency direction the surface models), B stands only as the already-shipped interim. Fork-back condition: if per-page scoping cannot be done as a scoped root + filter on the existing surface (i.e. it demands a new extraction mechanism or a new resolution environment), stop and report needs_decision rather than widening. Downstream: #11942 stays pm:blocked behind this card.

Correction to the report comment above (5415451124) — sanitizer damage, found by reading it back. Two angle-bracket tokens inside JSON string values were eaten; the JSON is still valid and every machine-parsed field is intact, so this is a repair-in-place note rather than a rewrite (rewriting a correct card is the worse failure).

implementation_shape_C.surface_placement reads "buildFileName is ____". It should read: buildFileName is label, then two underscores, then the page path with separators flattened, then two underscores, then the block ordinal — which is why a distinct label per root is load-bearing when two roots share one tree.
verification[3].restored reads "git checkout HEAD -- ;". The elided token is the path packages/spec/scripts/check-skill-examples.ts.

Nothing else changed. Same mutation shape as the one already listed in deviations for the PR body, arriving a second time on the surface it was already known on.

PM review: ACCEPT — PR #12339, head 4a6b5a2 (round R6, session session_01NDGG54XF5gbTLdQzCtnaVV).

The adopted route C landed in its strongest form, and the fork-back condition was not needed: a fourth SourceRoot on the EXISTING client-SDK surface — no new Surface entry, no new resolution environment, no new extraction code. Per-page scoping is SourceRoot.pages (explicit list, walk short-circuited) with excludePages as the broad root's complement, and both read the ONE shared SDK_DOCS_PAGES constant, so the partition is true by construction rather than maintained twice. The two failure modes that scoping introduces are each closed by a new asserted invariant (assertDisjointSourceFiles — a page compiled twice in two resolution environments; assertScopedPagesExist — a renamed page silently restoring the TS2307 gap), both self-tested in both directions and against the real SURFACES.

The card's executable criterion is met and reverse-proven: the createFilter() fence compiles with 0 diagnostics; ablating the script back to base with markers left on disk reds with TS2307: Cannot find module '@objectstack/client' at the same statement and same column as the card's control. Corpus: 256 → 260 marked examples; skills+docs unchanged at 227 (partition, not subtraction) — and the #12308 REFUSE semantics are exercised, not regressed (data-service.mdx's non-parsing signature listing correctly drew a REFUSE naming the new docs-sdk root during the sweep and stays unmarked).

Honest census disposition accepted: 3 fences on client-sdk.mdx + 1 on data-service.mdx opted in; the 9 left unmarked have per-fence diagnostic readings (the page's documented continuation-fragment convention, zero TS2307 among them) and the in-page contributor notes now record the measurement instead of the retired constraint. The dev's #12342 (TS18046 catch-binding class, hung under #11942) is correctly separated from the coverage question.

Downstream: #11942's recorded unlock-action ("re-run the marking exercise; the remainder are the real divergences") is already executed and recorded here — remainder = 9 documented fragments + #12342, zero doc-vs-SDK divergences today. When PR #12339 lands I'll note that on #11942 for its owning lane to disposition.

Clause-②: does not fire — no packages/spec/src/** path. Normal queue path: ready + auto-merge once every check on 4a6b5a2 is green.
