finding(spec): RestApiEndpointSchema.handlerStatus is authorable but has zero runtime consumers — the 501 it is documented to cause comes from somewhere else #13823

Description

@huangyiirene

Filed out-of-scope from the published-skills factual sweep, flight ⑦ (skills/objectstack-api, card #13814, program #13658). Recording only — unassigned.

The measurement

handlerStatus (implemented / stub / planned) is an authorable key on RestApiEndpointSchema (packages/spec/src/api/plugin-rest-api.zod.ts). A repo-wide search for the identifier, excluding skills/** and test files, returns three hits and all three are in the declaring file itself:

  • plugin-rest-api.zod.ts:177 — the declaration on RestApiEndpointSchema
  • plugin-rest-api.zod.ts:1415 — the same enum re-declared on RouteCoverageEntrySchema
  • plugin-rest-api.zod.ts:1431 — a docblock saying adapters SHOULD warn when handlerStatus !== 'implemented'

Plus one CHANGELOG row. No consumer in packages/runtime, packages/rest, or anywhere else reads the key.

Why it is worth a card rather than a shrug

The key's documented effect is a specific runtime behaviour, and that behaviour has a different cause. DispatcherErrorCode.enum.NOT_IMPLEMENTED is emitted from exactly four sites — runtime/src/endpoint-executor.ts (three) and runtime/src/api-mapping.ts (one) — and every one of them is the declarative-endpoint executor refusing a target or a mapping it cannot serve. None consults handlerStatus. So an author who sets handlerStatus: 'stub' expecting the dispatcher to answer 501 gets an ordinary served route, and the declaration reports progress to nobody: RouteCoverageReportSchema is the only shape that would carry it outward and nothing constructs one.

This is the ADR-0049 enforce-or-remove class, and the same shape as #13613: a declared surface whose semantics no code implements. It is also a declared = enforced gap on the endpoint vocabulary — the same surface ApiEndpointSchema closed strictly in #5384 precisely so a typo could not parse green and configure nothing.

Two routes, for triage

  • Remove. Retire the key from RestApiEndpointSchema with a tombstone, and either retire RouteCoverageReportSchema alongside it or keep it as the report-only vocabulary it already is. Cheapest, and it matches the startup-scope posture for a key with no pull.
  • Enforce. Have the route registrar consult handlerStatus and mount a 501 stub for stub / planned. That is a real capability — a declared-but-unbuilt route answering an honest 501 instead of 404 — but it is new behaviour needing its own ruling, not a repair.

Recommendation: remove, unless someone can name a consumer that wants the coverage report. The evidence for "no pull" is that the key has shipped since the CHANGELOG row and nothing has grown to read it.

Provenance

Found while verifying the skill sentence "The dispatcher returns 501 NOT_IMPLEMENTED for stub and planned handlers", which flight ⑦ corrects in the skill text. Fixing the skill stops the false teaching; it does not close the declared-but-inert key, which is why this is a separate card.

            Two routes, for triage

            • Remove. Retire the key from RestApiEndpointSchema with a tombstone, and either retire RouteCoverageReportSchema alongside it or keep it as the report-only vocabulary it already is. Cheapest, and it matches the startup-scope posture for a key with no pull.
            • Enforce. Have the route registrar consult handlerStatus and mount a 501 stub for stub / planned. That is a real capability — a declared-but-unbuilt route answering an honest 501 instead of 404 — but it is new behaviour needing its own ruling, not a repair.

            Recommendation: remove, unless someone can name a consumer that wants the coverage report. The evidence for "no pull" is that the key has shipped since the CHANGELOG row and nothing has grown to read it.

            Provenance

            Found while verifying the skill sentence "The dispatcher returns 501 NOT_IMPLEMENTED for stub and planned handlers", which flight ⑦ corrects in the skill text. Fixing the skill stops the false teaching; it does not close the declared-but-inert key, which is why this is a separate card.

              finding(spec): RestApiEndpointSchema.handlerStatus is authorable but has zero runtime consumers — the 501 it is documented to cause comes from somewhere else #13823

              Description

              @huangyiirene

              Filed out-of-scope from the published-skills factual sweep, flight ⑦ (skills/objectstack-api, card #13814, program #13658). Recording only — unassigned.

              The measurement

              handlerStatus (implemented / stub / planned) is an authorable key on RestApiEndpointSchema (packages/spec/src/api/plugin-rest-api.zod.ts). A repo-wide search for the identifier, excluding skills/** and test files, returns three hits and all three are in the declaring file itself:

              • plugin-rest-api.zod.ts:177 — the declaration on RestApiEndpointSchema
              • plugin-rest-api.zod.ts:1415 — the same enum re-declared on RouteCoverageEntrySchema
              • plugin-rest-api.zod.ts:1431 — a docblock saying adapters SHOULD warn when handlerStatus !== 'implemented'

              Plus one CHANGELOG row. No consumer in packages/runtime, packages/rest, or anywhere else reads the key.

              Why it is worth a card rather than a shrug

              The key's documented effect is a specific runtime behaviour, and that behaviour has a different cause. DispatcherErrorCode.enum.NOT_IMPLEMENTED is emitted from exactly four sites — runtime/src/endpoint-executor.ts (three) and runtime/src/api-mapping.ts (one) — and every one of them is the declarative-endpoint executor refusing a target or a mapping it cannot serve. None consults handlerStatus. So an author who sets handlerStatus: 'stub' expecting the dispatcher to answer 501 gets an ordinary served route, and the declaration reports progress to nobody: RouteCoverageReportSchema is the only shape that would carry it outward and nothing constructs one.

              This is the ADR-0049 enforce-or-remove class, and the same shape as #13613: a declared surface whose semantics no code implements. It is also a declared = enforced gap on the endpoint vocabulary — the same surface ApiEndpointSchema closed strictly in #5384 precisely so a typo could not parse green and configure nothing.

              Two routes, for triage

              • Remove. Retire the key from RestApiEndpointSchema with a tombstone, and either retire RouteCoverageReportSchema alongside it or keep it as the report-only vocabulary it already is. Cheapest, and it matches the startup-scope posture for a key with no pull.
