Iris Platform Adapter for Hermes Agent (Iris x Hermes).
A plugin-based gateway adapter that runs an HTTP server *inside* the
``hermes gateway`` process. The native Android / Desktop app connects to it
with a pairing token and talks to the agent over a single HTTP transport
(chat, streaming, tools, media, pairing, push-token): JSON frames via
``POST /v1/frame``, events via SSE ``GET /v1/events`` (or long-poll), and
media via ``POST /v1/media`` / ``GET /v1/media/{id}`` (docs/19).
Zero new Python dependencies: ``httpx`` is a hermes core dep. Zero
hermes-core changes.
Milestone M1: the gateway core loop (text round-trip). The server binds and
authenticates devices (constant-time token check), the adapter emits
``message`` frames from ``send()`` and turns inbound ``message.send`` frames
into ``MessageEvent``s for ``handle_message()``.
Milestone M2: agent transparency. ``send()``/``edit_message()`` are mapped to
``message.start``/``message.update``/``message.stop`` (streaming), tool
progress is classified into structured ``tool.start``/``tool.end`` frames,
interim commentary becomes ``commentary`` frames, and the code-style
reasoning prefix is split into a ``reasoning`` field. Outbox and search land
in M3; media, push, and desktop land in later milestones (see
``docs/14-milestones.md``).
Milestone M4: media. Inbound uploads (``POST /v1/media``) are streamed to a
temp file, verified (size + sha256), re-sniffed, and cached via hermes
``cache_*_from_bytes``; the resulting refs attach to the next
``message.send`` as ``MessageEvent.media_urls``. Outbound ``send_*`` calls
register the (delivery-validated) file in the media registry and emit
``media.offer``; ``GET /v1/media/{id}`` streams the file back, re-checking
``validate_media_delivery_path`` at pull time.
Milestone M5: push + offline. Frames with no live subscriber are parked in
the outbox (M3) AND wake the device via the push backend (``push.py``: FCM
HTTP v1 primary, ntfy fallback, selected by ``IRIS_PUSH_BACKEND``).
``notification`` frames render in-app banners and mirror to push (channel
events, cron deliveries, approvals, clarifies); high-priority kinds push even
when a device is live. ``fcm.register`` rotates push tokens (registry + live
connection). The outbox enforces a row cap with a throttled prune notice.
Configuration in config.yaml::

platforms:
iris:
enabled: true
extra:
host: 127.0.0.1
port: 8790
home_channel: default
push_backend: fcm
outbox_retention_hours: 72
max_upload_bytes: 104857600
Or via environment variables (overrides config.yaml; secrets live in .env):
