 ## Notes & limits

-- Size guard: inbound audio must be ≤5 MB (same as other media).
+- Size guard: inbound audio must be ≤5 MB (matches the temp media store and transcript pipeline).
+- Outbound caps: Web can send audio/voice up to 16 MB (sends as a voice note with `ptt: true`); Twilio still uses the 5 MB media host guard.
 - If transcription fails, we fall back to the original body/media note; replies still go through.
 - Transcript is available to templates as `{{Transcript}}`; models get both the media path and a `Transcript:` block in the prompt when using command mode.

+- Outbound media from Claude (via `MEDIA:`) follows provider caps: Web resizes images to the configured target (`inbound.reply.mediaMaxMb`, default 5 MB) within hard limits of 6 MB (image), 16 MB (audio/video voice notes), and 100 MB (documents); Twilio still uses the Funnel host with a 5 MB guard.
 - Voice notes: set `inbound.transcribeAudio.command` to run a CLI that emits the transcript to stdout (e.g., OpenAI Whisper: `openai api audio.transcriptions.create -m whisper-1 -f {{MediaPath}} --response-format text`). If it succeeds, warelay replaces `Body` with the transcript and adds the original media path plus a `Transcript:` block into the prompt before invoking Claude.

 ## Goals
 - Allow sending an image with an optional caption via `warelay send` for both providers.
 - Allow auto-replies (Twilio webhook, Twilio poller, Web inbox) to return an image (optionally with text) when configured.
+- For the Web provider, also support audio/voice, video, and generic documents with sensible per-type limits.
 - Keep the “one command at a time” queue intact; media fetch/serve must not block other replies longer than necessary.
 - Avoid introducing new external services: reuse the existing Tailscale Funnel port to host media for Twilio.

 ## Provider Behavior
 ### Web (Baileys)
 - Input: local file path **or** HTTP(S) URL.
-- Flow: load into Buffer, **resize + recompress to JPEG** (max side 2048px, quality step-down) to fit under a configurable cap, then send via `sock.sendMessage(jid, { image: buffer, caption })`.
-- Size cap: default 5 MB; override with `inbound.reply.mediaMaxMb` in `~/.warelay/warelay.json`.
+- Flow: load into Buffer, detect media kind, and apply the right payload:
+  - Images: **resize + recompress to JPEG** (max side 2048px, quality step-down) to fit under `inbound.reply.mediaMaxMb` (default 5 MB) but never above the Web hard cap (6 MB).
+  - Audio/voice and video: pass through up to 16 MB; set `ptt: true` for audio to send as a voice note.
+  - Everything else becomes a document with filename, up to 100 MB.
 - Caption uses `--message` or `reply.text`; if caption is empty, send media-only.
-- Logging: non-verbose shows `↩️`/`✅` with caption; verbose includes `(media, <bytes>B, <ms>ms fetch)`.
+- Logging: non-verbose shows `↩️`/`✅` with caption; verbose includes `(media, <bytes>B, <ms>ms fetch)` and the local/remote path.

 - When `--media` is a local path, copy to temp dir (`~/.warelay/media/<uuid>`), serve at `/media/<uuid>` on the existing Express app started for webhook, or spin up a short-lived server on demand for `send`.

 - For completeness: when inbound Twilio/Web messages include media, download to temp file, expose templating variables:
   - `{{MediaUrl}}` original URL (Twilio) or pseudo-URL (web).

 - Audio/voice notes: if you set `inbound.transcribeAudio.command`, warelay will run that CLI (templated with `{{MediaPath}}`) and replace `Body` with the transcript before continuing the reply flow; verbose logs indicate when transcription runs. The command prompt includes the original media path plus a `Transcript:` section so the model sees both.
 
 ## Errors & Messaging
 - Local path with twilio + Funnel disabled → error: “Twilio media needs a public URL; start `warelay webhook --ingress tailscale` or pass an https:// URL.”
-- File too large (>5 MB) → “Media exceeds 5 MB limit; resize or host elsewhere.”
+- File too large → error mentions the applicable cap (5 MB for Twilio host, 6/16/100 MB for Web image/audio-video/doc respectively).
 - Download failure for web provider → “Failed to load media from <source>; skipping send.”
