- Transcribe: sanitize the caller-supplied multipart filename (CR/LF
would inject Content-Disposition headers; upload metadata is
untrusted), always send the required model/response_format fields,
parse MIME parameters before extension matching, and give audio/opus
its own .opus extension.
- doRaw: a response larger than maxResponseBytes is now an error, not a
silent truncation.
- Shared plumbing: requireBaseURL() + newRequest() helpers replace the
7x-duplicated guard/error string and the triplicated request
building across doJSON/doRaw/Health.
- Health: non-2xx now returns *llm.APIError (package convention,
programmatically distinguishable from transport failure) instead of
a one-off unexported error type.
- Speak: reject negative Speed; speechMIME no longer accepts video/*
Content-Types.
- image.go: Generate/Edit share one sdWire validate+map helper.

- New leaf package `audio` (ADR-0017): SpeechModel/SpeechProvider and
TranscriptionModel/TranscriptionProvider with imagegen conventions
(zero value = backend default, functional options + Apply, bytes
in/out, never URLs). Root re-exports added.
- imagegen.Editor (ADR-0018): optional image-to-image interface —
EditRequest carries the generation knobs plus Init image and
denoising Strength; separate interface so existing Models keep
compiling.
- provider/llamaswap implements all of it: POST /v1/audio/speech (JSON,
raw-audio response, MIME from Content-Type with format fallback),
POST /v1/audio/transcriptions (multipart, response_format=json),
ListVoices (GET /v1/audio/voices?model=, tolerant of string-list and
object-list shapes), POST /sdapi/v1/img2img (txt2img wire +
init_images/denoising_strength, shared image decode), and Health(ctx)
(GET /health) — a cheap liveness probe for often-offline hosts.
- Hermetic httptest coverage for every new wire shape and validation
path; README sections + support-matrix footnote updated in the same
commit (also corrects the stale /v1/images/generations claim — the
image path has been SDAPI since the seed fix).
First consumer: mort's llamaswap media tool cluster (status / image /
TTS / STT agent tools against the netherstorm host).
