Diagnosed from a live voice session (e1b9fccb90ef): three turns failed with
raw '**Error:** HTTP 502 ... hermes-{claude,codex}-broker' because the agent
pod hosting the model brokers rolled mid-conversation. The voice client
correctly refused to speak the error envelope, but it then dropped the user's
utterance and forced them to repeat it three times.
Voice: on a TRANSIENT provider error (5xx/502/'error sending request'/timeout),
conversation mode now re-runs the errored turn in place through the app's own
regenerate action (which truncates the errored turn — no duplicate user
message) and stays in Thinking so its cues cover the reconnect gap. Bounded to
MAX_TRANSIENT_RETRIES (2); a non-transient error or an exhausted budget still
drops cleanly to 'let's try that again — listening'. The raw error is never
spoken. New probe scenarios cover retry-then-recover and the bounded-then-drop
path; source contract updated.
STT: the same session mis-transcribed 'CUI' as 'cue'. Prime the default
initial_prompt with the domain acronyms the user uses (CUI, FOUO, DoD, NIST,
CMMC, FIPS, RMF, POA&M, ATO, SBU) so they bias to uppercase forms.

Default final beam 5 -> 2: the accuracy/speed knee - most of beam
search's benefit at ~2x greedy instead of ~5x, protecting commit
latency on the Jetson (still env-overridable via
HERMES_STT_FINAL_BEAM_SIZE). Prompt now also primes common names (Amy,
Claude, Hermes) so 'Amy' stops transcribing as 'aiming'.

Proper nouns (Córdoba, Cancún) and dropped words came from decoding the
committed transcript with the small model. The image already ships
large-v3-turbo, so the final decode now uses it with beam_size=5, a
temperature fallback ladder, and a proper-noun/accents initial_prompt
that fixes first-pass capitalization and diacritics across EN/ES/RU;
the rolling previews stay on tiny at greedy so the on-the-fly feel is
unchanged. The accurate decode runs in the speculative predecode during
the end-of-speech silence and is cache-reused at commit, so perceived
latency stays low. All decode knobs are env-overridable for on-device
tuning (beam/temperature/prompt), with small as the guaranteed-present
rollback if turbo underperforms on the Jetson. 206 STT tests pass.

Port the original #27 detected-language pipeline onto the verified PR #39 prerequisite while preserving the current-main conversation instrument and host continuity changes.
Keep voice selection server-side with no user selector or client voice field. Reuse 207c16ab only for its stricter exact-code trust boundary, omitting malformed or absent language so Piper defaults to Amy.
