fal: put indexed endpoints in activity OpenAPI documents - #606
GET /v1/openapi/fal?activity= omitted endpoints that GET /v1/schemas/fal still lists. Almost every missing id is a deprecated catalog row with a stored input schema (fal-ai/veo3.1, Kling v2.1, Sora 2, Aura Flow, DiffRhythm, and the non-fast Seedance paths). The activity document now includes those rows. The bare document (no ?activity=) stays live models only. A model is still in endpoint_id only when it has an input schema, and AsyncAPI rows stay out of the HTTP queue document.
fal-ai/whisper is not in the active models search, the deprecated superset, or the public gallery. A direct endpoint_id lookup still returns its queue OpenAPI, with metadata: null and category speech-to-text on info['x-fal-metadata']. The poll now requests that one id and classifies it as audio. It shows up in the audio document after the next sync. A 404 on that lookup is skipped.
fal-ai/flux-2-trainer is category training, and fal-ai/hunyuan3d/v2 and fal-ai/hyper3d/rodin are *-to-3d. Both classify to null on purpose: training and 3d are outside the six-activity enum. They stay out of the activity documents.
Two schema-index ids still will not match the activity enum, because they have no HTTP input schema to publish:
minimax/h3-max/director is AsyncAPI (a websocket oneOf, not a queue POST body).
kotoba-technologies/kotoba-streaming-stt/v1/realtime, kotoba-technologies/kotoba-sts/v1/realtime_voice, and kotoba-technologies/kotoba-tts/v2/tts/ws have no stored input schema.

After deploy and a FAL sync, fal-ai/veo3.1 is in GET /v1/openapi/fal?activity=video with input_ and output_ schemas, and fal-ai/whisper is in ?activity=audio the same way.
Summary by CodeRabbit
Improvements
Activity-specific API documents now include deprecated models that match the selected activity; unfiltered listings continue to exclude deprecated models.
FAL model listings can include configured endpoints absent from the active listing, including audio models identified through their API specifications.
Models with missing category information are handled more consistently, and expired retirement dates are reflected in deprecation status.
?activity= was built from live models only, so deprecated endpoints that
GET /v1/schemas/fal still lists never appeared. The bare document stays
live-only, and AsyncAPI rows stay out. fal-ai/whisper is missing from the
active search; look it up by endpoint id and read its category from the
OpenAPI document.

Walkthrough
FAL sync now resolves optional model metadata and fetches configured unlisted endpoints. Activity-filtered OpenAPI documents include deprecated models and their stored schemas, while unfiltered documents continue to exclude deprecated models.
Changes: FAL endpoint indexing and activity documents
Layer / File(s)
Summary
Resolve FAL model metadata src/server/providers/fal.ts
FAL model metadata and category are optional. Category resolution uses listing metadata or embedded OpenAPI metadata. When metadata is absent, a valid past retires_at timestamp marks a model as deprecated.
Fetch and ingest additional FAL endpoints src/server/providers/fal.ts, src/server/providers/fal.test.ts, src/server/providers/fal-chat-facts.test.ts
The FAL sync fetches configured unlisted endpoints and uses resolved metadata during classification and model output. Tests cover Whisper lookup and indexing, including speech-to-text activity metadata and retirement status.
Include deprecated models in activity documents src/server/provider-openapi.ts, src/server/provider-openapi.worker.test.ts
Unfiltered queue documents exclude deprecated models. Activity-filtered documents include deprecated models and their stored schemas. Tests also verify that AsyncAPI-only activity selection returns 400 spec_requires_selector.
TanStack/modelschemas#573: Introduces the FAL queue OpenAPI document and its activity-narrowed assembly path, which this PR updates.
Merge Risk: Low · previous review 5aa0c
The change adds deprecated models to activity-filtered OpenAPI documents and indexes unlisted FAL endpoints. One test fails when run on its own, but runtime behavior is not affected. This is mergeable, and the test should be made independent soon.

Full details: Title check
Explanation
The title names the fal provider and the main change: indexed endpoints now appear in activity OpenAPI documents. The raw summary and objectives confirm that GET /v1/openapi/fal?activity=... now includes indexed endpoints missing from the listing, and fal-ai/whisper is requested directly. The title is specific and matches the primary change, though it does not mention the whisper lookup or deprecated-model handling.
Full details: Linked Issues check
Explanation
Issue #605 has two coding asks. (1) Put every indexed endpoint for an activity into that activity's ?activity= document with input_/output_ schemas and x-modelschemas-model. (2) Explain and index the endpoints missing from the index, if FAL lists them.
Ask 1: src/server/provider-openapi.tsloadQueueModels now drops the deprecatedAt IS NULL filter when activity is set. Deprecated rows with stored input schemas (for example fal-ai/veo3.1, Kling v2.1, Sora 2) now appear in the activity document. The bare document still filters to live models. The PR tests cover this case.
Ask 2: src/server/providers/fal.ts adds FAL_UNLISTED_ENDPOINT_IDS = ['fal-ai/whisper']. appendUnlistedFalModels requests that id directly with expand=openapi-3.0, in both fetchSpec and listModels. Category resolves from the embedded x-fal-metadata.category (speech-to-text). FAL_CATEGORY_OVERRIDES maps that category to audio, so whisper enters the audio document. A 404 is skipped.
The PR excludes three groups by design: minimax/h3-max/director (AsyncAPI, no HTTP queue body), three kotoba-technologies realtime ids (no stored input schema), and training or 3D ids such as fal-ai/flux-2-trainer, fal-ai/hunyuan3d/v2, and fal-ai/hyper3d/rodin (outside the six-activity enum). The first two groups cannot meet the issue's schema requirement. The issue acceptance requires equal x-modelschemas-model id sets, so these four schema-index ids remain a literal gap. The PR discloses that gap. The training and 3D ids sit outside the enum that the acceptance criteria use.
Runtime confirmation (whisper appearing after a FAL sync, and count parity) cannot be proven from repository code. The code path and tests support the requirement.
Full details: Out of Scope Changes check
Explanation
Every changed hunk traces to issue #605 or to the stated PR behavior.
provider-openapi.ts: the activity-filter change implements ask 1. The doc-comment and queue description text update the documented behavior to match ('stored' endpoint schemas, live-only bare document). These are documentation of the same change.
fal.ts: FAL_UNLISTED_ENDPOINT_IDS and appendUnlistedFalModels implement the whisper lookup. modelCategory and openApiCategory supply the category that whisper's null listing metadata lacks. modelDeprecated applies the retires_at signal only to rows without metadata, which is the whisper-style unlisted row. providerMetadata is now omitted only when no category exists, and m.metadata?. null-guards follow from the nullable metadata type. All of these support handling unlisted rows.
Tests in provider-openapi.worker.test.ts, fal.test.ts, and fal-chat-facts.test.ts cover the deprecated-inclusion, AsyncAPI-exclusion, whisper classification, 404 skip, and unlisted-deprecation behavior.
No change is unrelated to the issue. No training, 3D, or non-FAL provider behavior changed. The fallback category logic runs for all FAL rows, but it changes results only where the listing category is missing, which previously caused a null dereference.

Make the video-enum assertion independent of test order.
The shared seed does not create fal-ai/veo3.1. If this test runs alone on a fresh database, the activity request returns spec_requires_selector and fails before the enum assertion.
Seed the model, endpoint, and schemas in this test, or move those rows into the shared beforeAll seed.

Accepted:appendUnlistedFalModels skipped every non-retryable FalFetchError (400/401/403), not just 404, without logging anything. A skipped id is missing from listModels, so the poller marks it deprecated and emits model.removed (poll-models.ts:1112), then re-adds it on the next good poll. Now only a 404 is skipped (the id really is gone); anything else throws, like the main crawl does. FalFetchError carries status; test added (403 rejects).
Challenged, kept:FAL_UNLISTED_ENDPOINT_IDS as an in-code list. It's a one-id ingest seed, not a catalog mapping table, so the catalog-data-in-DB rule doesn't apply. Revisit if it grows.
Challenged, kept:retires_at in the past → deprecated only when metadata is null. The listing's own status wins when present.
