Synchronous adapter for the ElevenLabs Scribe speech-to-text API, registered with the transcription manager, with settings for its API key, model and request timeout.

Adapters build their tenacity retry from transcription_retry and the TRANSCRIPTION_RETRY_* settings, and the async adapters poll using the TRANSCRIPTION_POLL_* settings instead of per-call arguments. Shared HTTP status codes move to common/http_status.py. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GSrMumb6qEQrBJdZ37NbfB

The manager only passes a Recording to async adapters, so raise a TypeError before calling the API. This also lets Pyright narrow the argument to a Path. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GSrMumb6qEQrBJdZ37NbfB
The synchronous Azure adapter rejects anything but a local file and the async AWS and Azure batch adapters anything but a Recording, before any client is created. This also lets Pyright narrow the Path | Recording argument in each start().

…iption test A data residency API key is rejected with a 401 by every stack but its own, including the global API the SDK calls by default. ELEVENLABS_BASE_URL now defaults to the EU stack and can be pointed elsewhere for a key issued on another one.

This looks very re-usable so maybe move to retry.py?

ah no afraid not - it depends on ApiError from the elevenlabs SDK

maybe we can skip this if env is local development? If basically our ENVIRONMENT=local we don't have to check this to even further minimise costs if we are building tests lets say for a new feature and we do make test?

What
Adds ElevenLabs Scribe as a transcription service and switches preprod over to it.
ElevenLabs adapter
elevenlabs_stt(common/services/transcription_services/elevenlabs.py), registered with the transcription manager.https://api.eu.residency.elevenlabs.io) by default. A residency key only works against the stack it was issued for, soELEVENLABS_BASE_URLmust match the key.speaker_0rather than being dropped.ELEVENLABS_API_KEY,ELEVENLABS_BASE_URL,ELEVENLABS_STT_MODEL(defaultscribe_v2),ELEVENLABS_STT_TIMEOUT_SECONDS(default 1 hour). Because the adapter is synchronous, the timeout, not the service's 10-hour limit, caps how long a recording it can handle.Shared retry and polling settings
retry_count/retry_delayarguments. These now go throughtranscription_retryinretry.pyand newTRANSCRIPTION_RETRY_*/TRANSCRIPTION_POLL_*settings. The defaults match the old hardcoded values.check()no longer takesretry_count/retry_delay.noqa: PLR2004s) are replaced with constants incommon/http_status.py.Adapter input checks
TypeErrorif they're given aRecording, and async adapters if they're given aPath, instead of failing later with a less obvious error.Infrastructure
ELEVENLABS_API_KEYadded to the SSM env secrets (placeholder value).TRANSCRIPTION_SERVICESis["elevenlabs_stt"]in the preprod workspace only; every other workspace keepsazure_stt_synchronous+azure_stt_batch. Preprod has no Azure fallback.Other
