Extend the sidecar and Python adapter to handle `voice` content
alongside `attachment`. Voice notes are inlined as base64 (same
size-cap logic), surfaced as `MessageType.VOICE`, and include an
optional `duration` field in fallback markers when bytes are
unavailable.
Switch `list_users`, `find_user_by_phone`, `create_user`,
`register_user_if_absent`, and `refresh_user_numbers` from the
Dashboard API (Bearer token) to the Spectrum API (Basic auth with
project credentials). Update response unwrapping to handle the nested
`data.users` envelope returned by Spectrum, add `_spectrum_host()`
resolver, `_basic()` header helper, and structured error helpers.
Update tests, docs, and plugin.yaml accordingly.
During `hermes photon setup`, allowlist the operator's number and set
their DM as the cron home channel when those env vars are unset. Without
this, the gateway denies the operator's own messages and cron has no
default delivery target. Re-runs never overwrite hand-tuned values.
Also teaches the sidecar's `resolveSpace` to accept a bare E.164 number
as a space identifier, resolving it to the user's DM space so
`PHOTON_HOME_CHANNEL` can be set to a phone number instead of an opaque
space id.
Make Photon iMessage a first-class persistent-connection channel like
Discord/Slack, using the spectrum-ts gRPC stream for both directions.
- Inbound: the sidecar forwards the SDK's app.messages gRPC stream to the
adapter over a loopback GET /inbound (NDJSON) instead of webhooks. Drops
the aiohttp webhook server, HMAC signature verification, public URL, and
PHOTON_WEBHOOK_* config; adapter reconnects with backoff.
- Management plane: device login uses client_id=photon-cli against the
single dashboard host (Bearer), matching the official photon-hq/cli;
find-or-create "Hermes Agent" project, enable Spectrum, rotate secret,
register user (with phone dedup), surface the assigned iMessage line.
- SDK projectId is the project's spectrumProjectId, not the dashboard id;
runtime creds persist to ~/.hermes/.env like every other channel.
- CLI: 6-step setup, webhook subcommands removed.
- Tests/docs updated for the gRPC flow; sidecar pins spectrum-ts ^1.17.1.

Photon now exposes attachment send (Ray Sun, photon-nousresearch), so
the Photon plugin gains outbound media to match the BlueBubbles iMessage
channel.
- sidecar: new /send-attachment endpoint wrapping space.send(attachment())
/ space.send(voice()); caption sent as a trailing text bubble.
- adapter: override send_image/send_image_file/send_voice/send_video/
send_document/send_animation. URL helpers cache to a local path first
(cache_image_from_url), file helpers pass through. Defense-in-depth
path re-validation before the path reaches the Node sidecar.
- _standalone_send (cron): send text first, then each media_file as a
/send-attachment call (is_voice -> voice builder).
- docs/README: flip the 'outbound attachments not wired' note.
Every other Hermes gateway channel onboards through a single setup
surface (paste a token / run the wizard) with no per-platform login
command. Photon's device-code flow is unavoidable because Photon mints
credentials via API rather than a copy-paste dashboard field, but
exposing it as a top-level `hermes photon login` verb broke channel
parity.
- Remove the `login` subcommand; setup already runs the device flow as
its first step. `--no-browser` moves onto `setup`.
- Rename `_cmd_login` -> `_run_device_login` (internal helper).
- Status / credential-summary hints now point at `hermes photon setup`.
- README updated to the one-command onboarding flow.
First-class iMessage support via Photon's managed Spectrum platform.
Targeted as a successor to the BlueBubbles adapter — Photon allocates
the iMessage line, handles delivery, and abuse-prevention so users
don't have to run their own Mac relay. Free tier uses Photon's shared
line pool.
Architecture:
- Inbound: signed JSON webhooks (X-Spectrum-Signature, HMAC-SHA256)
delivered to a local aiohttp listener. Dedupes on message.id,
rejects deliveries with >5min timestamp drift.
- Outbound: small supervised Node sidecar that runs the spectrum-ts
SDK. Photon does not currently expose a public HTTP send-message
endpoint; the sidecar is the only way to call Space.send() today.
When Photon ships an HTTP send endpoint we collapse the sidecar
into _sidecar_send and drop the Node dep — every other layer of
the plugin stays the same.
- Setup: 'hermes photon login' runs the RFC 8628 device-code flow;
'hermes photon setup' creates a Spectrum-enabled project, creates
a shared user (free tier), installs the sidecar's npm deps.
- Webhook management: 'hermes photon webhook register|list|delete'.
- Credentials persisted under credential_pool.photon /
credential_pool.photon_project in ~/.hermes/auth.json.
Plugin path (not built-in) — per current policy (May 2026), all new
platforms ship under plugins/platforms/. Registers itself via
ctx.register_platform() + ctx.register_cli_command(), zero edits to
core gateway code.
Tests cover:
- HMAC-SHA256 signature verification (happy path, tampered body,
wrong secret, drift, missing v0 prefix, empty inputs, non-integer
timestamp)
- Inbound dispatch for text DMs, group ids (any;+;...), and
attachment metadata markers
- Deduplication window
- check_requirements gating when Node is absent
- Device-code flow: request, header-based token return,
body-fallback token return, access_denied propagation
- Project/user/webhook API clients with mocked httpx
Known limitations (current Photon API):
- Attachments are metadata only — no download URL yet
- Outbound attachment send not wired (sidecar can add easily)
- Reactions / message effects not exposed yet
