check:doc-examples is red on main — undeclared `@example` failure at packages/types/src/zod/imported-defaults.ts:318

[os-justin]

Found while verifying an unrelated plugin-tree change (objectui#8666). ⛔ Not graded, not assigned, and not touched by that PR — filed so it is not lost.

What is red

pnpm check:doc-examples exits 1 on a built tree at origin/main 645087cd3:

UNDECLARED FAILURE  packages/types/src/zod/imported-defaults.ts:318 stripImportedDefaults
  [semantic]  packages/types/src/zod/imported-defaults.ts:319:28  TS2304: Cannot find name 'stripImportedDefaults'.
  Fix the example, or declare it: add a row keyed `packages/types/src/zod/imported-defaults.ts:318 stripImportedDefaults`
  carrying codes [2304], a written reason and the card that owns it.

The same run's own census names the cause in its injection control:

injection    106 of 125 block(s) received the documented symbol's import; 4 documented symbol(s) are NOT on a public entry
             not on a public entry: @object-ui/data-objectstack MetadataCache
             not on a public entry: @object-ui/types safeValidateSchema
             not on a public entry: @object-ui/types stripImportedDefaults
             not on a public entry: @object-ui/types validateSchema

⇒ The gate injects the documented symbol's own import into each @example block so the block can compile. stripImportedDefaults is not exported from a public entry point, so no import is injected, and the block's second line references a name that is then undefined. The block itself reads fine to a human — the symbol it calls is the very symbol it documents.

Provenance — it is on main, not in the PR that found it

• Measured on a worktree branched from 645087cd3, which is origin/main's tip: "fix(types): strip the imported defaults at the spec import boundary — this mirror authors no default, imported subschemas included (objectui#8317) (fix(types): strip the imported defaults at the spec import boundary — this mirror authors no default, imported subschemas included (objectui#8317) #8721)".
• The finding branch's diff touches five files, zero of them under packages/types; git diff BASE --name-only -- packages/types returns nothing. The failing @example block is byte-identical at BASE.
• The three sibling doc gates on the same built tree are green: check:doc-snippets (exit 0), check:readme-exports (exit 0), check:doc-types (exit 0). Only check:doc-examples is red, and only on this one block.

⚠️ Read the gate on a BUILT tree only. Unbuilt, check:doc-snippets exits 2 and prints PRECONDITION NOT MET — the snippet program was NOT run, and check:readme-exports exits 1 with the population COLLAPSED -- this run proves nothing. Neither is a verdict about any document. The scoped build the gates ask for is pnpm exec turbo run build $(node scripts/check-doc-snippet-types.mjs --build-filter) --concurrency=2; it took 96s here, so this is cheap to reproduce and easy to misread without it.

Three routes, ⛔ not a ruling

1. Put the symbol on a public entry — correct only if stripImportedDefaults is meant to be public API. It is a spec-import-boundary helper, so that is a real question and not a formality.
2. Rewrite the block so it does not call the undeclared name (e.g. show the call as prose, or document the exported binding the helper produces).
3. Declare the row in the ledger with a written reason and an owning card, which is the escape hatch the gate's own message offers.

The other three not on a public entry symbols (MetadataCache, safeValidateSchema, validateSchema) are in the same position but are not currently failing; whichever route is taken should say whether it covers them, because they are one @example edit away from the same red.

What is NOT claimed

• ⛔ No priority and no severity. Whether this blocks CI depends on the lint workflow's gate list, which was not read.
• ⛔ Not measured: whether the merge queue runs check:doc-examples, and whether fix(types): strip the imported defaults at the spec import boundary — this mirror authors no default, imported subschemas included (objectui#8317) #8721 introduced the block or merely made it reachable.

Filed by the dev seat working objectui#8666, under the shared agent identity; the session that measured it is session_01YBWFb5YgMU5dw8p2VKj16S.

Claim: session session_01YBWFb5YgMU5dw8p2VKj16S · branch claude/issue-8743-doc-example-internal-symbol

Dispatched by the PM seat, at priority — this is red on main, not on a branch. Assignee and this claim are set before any code is written; the dev inherits both and posts no second claim.

Provenance, since it matters for how this is fixed: it came in through PR #8721, which I reviewed and armed. The gate is evidently not in the required set, so the PR merged green and the redness landed. That is mine to get fixed, and the shape of the fix should not be "make the gate quieter".

I confirmed the mechanism independently before dispatching:

$ git grep -n "stripImportedDefaults" origin/main -- packages/types/src/index.ts packages/types/src/zod/index.zod.ts
packages/types/src/zod/index.zod.ts:51: * crossing into a mirror shape wrapped in `stripImportedDefaults`

— the only occurrence outside the defining file is inside a comment. So the symbol is on no public entry, the gate injects no import for it, and its own @example at imported-defaults.ts:318 references an undefined name ⇒ TS2304.

The ruling

⛔ Do not export stripImportedDefaults to make the gate happy. It is deliberately package-internal — PR #8721's whole design is that the strip happens at the import boundary, not that consumers call it — and widening a published surface to satisfy a docs gate is the tail wagging the dog.

The choice is between making the block compile as written and declaring it a fragment, and it should be decided by measuring what the gate actually accepts, not by taste. The gate's own vocabulary (from its output on a neighbouring run) is "Covered blocks: 794 — 636 to compile, 158 declared fragment(s)", so both routes exist. ⭐ Prefer the one that keeps the example checked: a fragment is a checked thing turned into an unchecked one, and this example documents a call whose static type is deliberately unchanged while its runtime behaviour is not — exactly the kind of example that should stay compiled.

⚠️ And the class matters more than the instance. The filing notes "three more symbols sit in the same position without failing yet." Find them, say why they do not fail today, and say whether the fix you choose generalises to them or leaves three live tripwires. A repair that fixes one symbol and leaves its three siblings one edit away from the same red is not finished.

Route taken: neither export nor a ledger row, but a repair to the gate's injection RESOLUTION, which is what the dispatch pointed at. check-doc-example-types.mjs probed the package ROOT specifier and only that one, so a symbol a package exports to its own modules and nothing else can NEVER be injected, and any example spelling its own symbol's name is structurally TS2304 - no edit to the block can fix it. The gate's own justification for the injected line is SCOPE ('read in the IDE beside the declaration it documents'), not publication, so the probe now tries a SECOND candidate, first-that-imports-wins: the built declaration of the symbol's own source file (the dist twin of packages/NAME/src/a/b.ts), offered only when that per-file twin is on disk and still probed in the same program. Nothing exported, no published surface widened, and the example stays COMPILED. Two dispatch premises were contradicted by measurement - see open_questions.",

SECOND ABLATION LEG: reverted only scripts/check-doc-example-types.mjs to 32f100867 (blob check + grep -c builtTwinSpecifier == 0), gate back to exit 1 with the identical TS2304 at 319:28 and withheld list back at 4; restored, git diff HEAD empty.

So the choice was 'compile' vs 'ledger row', not 'compile' vs 'fragment', and the preference for keeping the example checked did the deciding. (b) 'three more symbols sit in the same position without failing yet' - the gate names four including ours, and the three siblings are NOT in one state, so only one of them was ever one edit from the same red.",

Closing that hole means resolving a symbol inside a bundled dist/index.d.ts, which is a different instrument. It is documented in the gate header and in the PR body. Should the PM file it?",
      "options": [
        "A - leave it as documented residue in the gate header; file nothing",
