Context

Different partitions need different transcription endpoints and instructions.

Expected behavior

Indexation presets can select an STT endpoint and ASR prompt, so partitions inherit the appropriate transcription behavior without global changes.

Depends on #872, #873, and #874. Split from #865.

Summary by CodeRabbit

  • New Features

    • Indexation presets can select speech-to-text endpoints and transcription prompts for audio processing.
    • Added “STT endpoint” and “Transcription prompt” options, including a “Use default” choice.
    • Prompt library indicators distinguish default fallback transcription prompts from unused prompts.
  • Bug Fixes

    • Audio processing now consistently applies the active indexation preset and reports unavailable selections instead of silently falling back.
    • Prompt usage and endpoint renaming now accurately reflect preset-based transcription configuration.
  • Documentation

    • Clarified prompt and endpoint selection, direct extraction, worker requirements, and supported audio loaders.

📝 Walkthrough

Walkthrough

Indexation presets now select STT endpoints and ASR transcription prompts for applicable audio and video files. The indexer applies these settings with global fallbacks. The admin UI, persistence layer, tests, and documentation reflect the new behavior.

Changes

Preset-scoped transcription

Layer / File(s) Summary
Preset configuration and persistence
openrag/core/config/indexation_pipeline.py, openrag/core/config/model_endpoints.py, openrag/services/persistence/*, openrag/services/orchestrators/*, openrag/core/models/preset.py, openrag/api/schemas/admin/*, tests/integration/repos/*, tests/unit/core/config/*, tests/unit/services/persistence/*, tests/unit/services/orchestrators/*, tests/unit/api/schemas/admin/*
Indexation presets accept STT and ASR prompt selections. Named model endpoints preserve registry identities. Prompt reference counting and STT endpoint renames cover preset selections. Partition-level prompt validation remains limited to final-answer prompts.
Worker transcription resolution and caching
openrag/services/workers/indexer_pool.py, openrag/services/workers/parsers/parser_dispatcher.py, openrag/services/inference/parsers/openai_audio.py, tests/unit/services/workers/test_indexer_pool.py, tests/unit/services/inference/parsers/test_openai_audio.py
Workers apply task-local preset configuration, detect OpenAI audio routing, resolve selected prompts and endpoints strictly, settle rejected submissions, and pass embedder windows to chunkers. Audio clients and limiters use named endpoint keys with bounded LRU caches.
Indexation preset administration
ui/src/pages/admin/presets.tsx, ui/src/pages/admin/preset-config.ts, ui/src/pages/admin/prompts.tsx, ui/src/pages/admin/presets.test.tsx, ui/src/pages/admin/prompts.test.tsx, ui/src/lib/*, ui/src/lib/api/partitions.ts
The preset form adds STT endpoint and transcription prompt fields. The default STT option persists as null. ASR prompt badges, warnings, descriptions, and tests use preset selection semantics.
Selection behavior documentation
docs/content/docs/documentation/API.mdx, docs/content/docs/documentation/env_vars.md
Documentation describes preset-scoped ASR prompts and STT endpoints, global fallbacks, audio-loader conditions, LocalWhisper behavior, and MOSS transcript configuration.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 1ed9d

This PR allows presets to choose transcription providers and prompts, but an incompletely configured selected endpoint can silently use global settings and send media to the wrong provider. Validation should be fixed or explicitly accepted before merge; the remaining alias and lifecycle concerns are bounded follow-ups.

Assert that _build_chunker forwards the embedder window.

The stub accepts _window with a default and discards it. No test proves that _build_chunker and _build_chunker_from_config pass the resolved window to create_chunker. A regression that drops the window would silently change the chunker's hard token bound and truncate content before embedding.

Capture the received argument in one of these stubs.

Went through this one carefully because the ContextVar is doing a lot of load-bearing work, and it holds up: IndexerWorker is an in-process object, parse_stage wraps the parser in run_with_optional_timeout -> asyncio.wait_for, and OpenAIAudioClient.parse awaits both resolvers inline, so nothing crosses a thread or a detached task. I confirmed the value survives that chain and that two concurrent process_file calls stay isolated. End-to-end wiring checks out too (_resolve_indexation_dispatch_config dumps the full IndexationPipelineConfig, so both new keys reach the actor). Unit suite, ruff, tsc, eslint and the three UI suites all pass locally.

Nothing blocking below — three notes on things this PR makes reachable that weren't before.

An indexation preset can select a named STT endpoint, and a stale name
already fails the file rather than silently switching providers. An
endpoint that exists but carries no model name slipped through that
guard: OpenAIAudioClient reads a missing endpoint/model as "no endpoint
configured" and transcribes with the TRANSCRIBER_* fallback, dropping
the selection's extra request options along with its model. The file
then succeeds and persists a transcript produced by a provider the
preset did not select, with nothing surfacing the substitution.

The API cannot create such a row (validate_stt_fields guards both the
create and update paths), but seed_defaults writes the STT seed straight
from TRANSCRIBER_MODEL through the repo, and model_endpoints.model_name
is nullable — so an empty TRANSCRIBER_MODEL persists one. Validate a
selected endpoint here instead. An unset selection keeps degrading to
the parser's fallback, which is the historical contract.

Also name the rename alias for the new registry name. _alias_renamed_name
receives the pre-rename row, so the config it built was still named
old_name under both aliases until the final load_all(). That name is the
stable registry identity and now keys OpenAIAudioClient's limiter and
client caches, so a request landing in the alias window keyed its caches
under the retired name.

Renaming an endpoint reloaded presets via refresh_if_stale() and reached
load_partitions() only in the elif branch. That branch is dead in
production: di/container.py always passes a preset_service.

refresh_if_stale() reloads partitions only when the preset revision moved,
and the revision is bumped by the rename cascade only for model types in
model_endpoint_repo's preset-key maps. embedder is in neither map, so an
embedder rename updated partitions.embedder in the database, bumped no
revision, and left the in-memory config pointing at the old name. Indexing
and search on that partition then failed with an unknown embedder until the
process restarted.

Use the refresh_if_stale() return value instead of the elif, so partitions
reload whenever the preset path did not already reload them. This keeps the
single reload the elif was introduced for when the revision does move.

…ails

_refresh_preset_config_if_stale ran unguarded inside add_file's admission
block. latest_revision() raises outright when the preset_configuration_revision
row is missing, and asyncpg surfaces any transient connection fault the same
way, so a blip turned every upload — of every file type, in every partition —
into a 500.

The probe is an optimization that lets a replica notice presets another replica
changed, never a precondition for accepting a file. Swallow and log, as every
other cache refresh on this path already does; the cost is at most one dispatch
on a stale preset, which is the state the caller was already in.
Presets reference endpoints by name in pipeline_presets.config (JSONB) with no
foreign key, and delete_and_promote_default guarded only against removing the
last endpoint of a type. Deleting an endpoint a preset still named therefore
left a dangling reference, and indexation resolves an explicit selection
strictly: every audio upload on a preset whose stt named the deleted endpoint
failed permanently with "Unknown STT endpoint", with nothing surfaced at delete
time. PgPromptRepository.delete already clears a deleted ASR prompt's selection
for exactly this reason; endpoints had no such cascade.

Clear every preset key naming the endpoint inside the delete's own locked
transaction, before the row goes away, reusing the same key maps rename()
cascades through (so an llm delete clears all four of its keys). Clearing
rather than repointing returns the preset to the documented "use the default"
state, and the last-endpoint guard means a default always survives to fall back
to. The service then reloads the preset and partition caches, or this replica
would keep resolving the dead name out of memory.

Padded values are matched with btrim, as rename() does, since indexation trims
selections before lookup.
