ARIA 913ee91024 M4: media upload/download/playback (both directions)
Gateway plugin:
- media.upload (chunked binary) -> size/sha256 verify + MIME re-sniff ->
  cache_*_from_bytes -> media.upload.ack
- media.offer / media.pull (chunked) for agent-sent media, delivery-path
  security re-checked at pull time
- send_* overrides mint media_id and emit media.offer
- message.send media_refs resolve to cached inbound media
- per-send + per-chunk timeouts so a stalled peer can't starve the rest

App (Kotlin CMP):
- Protocol: media frame types/payloads/builders
- GatewayClient: binary session, uploadMedia (chunked + streaming sha256),
  pullMedia serialized via Mutex so concurrent offers don't interleave
- ChatStore/IrisController: MediaItem, attachments, auto-pull on offer
- Platform media: SAF picker, ExoPlayer (audio mini-player + video), image
  loader, FileProvider document open (Android); AWT-free desktop actuals
- ChatScreen: attach button + chips, media rendering, keyboard dismiss on send

UI polish:
- preserve image aspect ratio (no stretching), cap dominant dimension
- adjustResize so only chat content squeezes for the keyboard
- clear focus (hide keyboard) on send

Docs: media.upload.ack in 04-wire-protocol.md + frames.schema.json +
07-media.md; M4 marked complete in 14-milestones.md.

Tests: 17-test tests/gateway/test_android.py suite passes.

Iris × Hermes

A native Android + Desktop experience for hermes-agent, connected through a gateway platform plugin.

⚠️ HARD RULES

  1. hermes-agent/ is a read-only research reference. It is git-ignored and must NEVER be committed, pushed, or shipped. We only install our plugin into a live hermes home (~/.hermes/plugins/android); we never modify hermes core.
  2. ADB is installed and a device is connected (a5ca2a4b, Xiaomi MIX 2S, Android 10 / API 29). Use it to install/launch/debug the app on-device.

Start here

📚 The full implementation reference library is in docs/. Read docs/00-overview.md first, then follow the numbered docs.

The three deliverables (this monorepo)

Path What
gateway-plugin/ Python hermes platform plugin (android). Runs in the hermes gateway process; opens a WebSocket server the apps connect to. Zero new Python deps, zero hermes-core changes.
app/androidApp Native Kotlin + Jetpack Compose client.
app/desktopApp Kotlin + Compose Multiplatform client — the Android app, tweaked for a big screen (shares app/shared).

The Android and Desktop clients live in one Compose Multiplatform Gradle project (app/) with a shared KMP module (app/shared).
