only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.
Review comment at @apps/server/src/speech/CloudSpeech.ts at line 174:
Update the existing configured-key assertion for the service’s configured result
to include gemini: false alongside the existing key states, so it matches the
returned configuration before the transcription checks run.

Add focused coverage for the Gemini protocol path.
The existing apps/server/src/speech/CloudSpeech.test.ts provider table covers only OpenAI and xAI. Extend that test suite to check Gemini’s header, JSON request modes, and candidate-part response decoding. Those assertions would catch request-contract regressions without testing a wrapper layer. (raw.githubusercontent.com)
As per coding guidelines, “Backend behavior changes ship with focused tests for that behavior.”

Review comment at @apps/server/src/speech/CloudSpeech.ts around lines 251 - 255:
Extend the provider table in the CloudSpeech test suite with focused Gemini
protocol coverage: assert the API-key header and JSON request modes, and verify
decoding of candidate-part responses. Exercise the CloudSpeech request and
response behavior directly rather than testing a wrapper layer.

Report an empty Gemini candidate array as unavailable.
A blocked prompt can return no candidates. If Gemini returns an empty array, the caller receives a successful empty transcript and reports “No speech was detected” instead of a provider error. Keep empty text in a returned candidate valid.

Review comment at @apps/server/src/speech/CloudSpeech.ts around lines 290 - 296:
Update the Gemini response handling to report an empty candidates array as
unavailable instead of returning a successful empty transcript. Preserve empty
text when a candidate is present, and add coverage for both cases in the
relevant tests.
