ASR and extraction are separate, independently swappable roles resolved per
locale from config. All three locales point at the same OpenRouter models today
(whisper-1, gemini-3.7-flash); the indirection stays because Persian ASR is the
weakest link and repointing only `fa` must not be a code change.
The model emits a deliberately flat wire shape rather than the internal
discriminated unions — strict json_schema mode has poor union support — and
toVoiceIntent narrows it. That normalizer is total: a missing or malformed
payload yields a shape the resolvers report as unresolved rather than one that
throws.
The prompt supplies catalog codes with labels in the actor's locale, so the
model matches spoken words rather than translating, and carries per-locale
tooth vocabulary. English gets an explicit warning that a bare two-digit number
is ambiguous under Universal numbering, and must not be treated as FDI unless
the speaker said so.
From review of this commit:
- only an actually FDI-shaped code takes the explicit branch; fdi:"6" alongside
valid arch/side/position used to lose the tooth entirely
- an unrecognised due kind passes through to be flagged, instead of collapsing
to null and looking like no deadline was ever spoken
- vendor error bodies stay out of the thrown message and the default log level;
a 4xx can echo the request back, transcript included
- the chat call sets provider.require_parameters so OpenRouter only routes to
endpoints that honour the JSON schema, rather than ones treating it as a hint
- an unknown locale in VOICE_ENABLED_LOCALES now fails at boot like an unknown
provider id, instead of silently disabling the microphone everywhere
