The advisory lint-diff bot flagged 17 new ty diagnostics. 6 are
`unresolved-import` for httpx/aiohttp/pytest, which is structural
(CI lint env has no project deps) and matches every other platform
plugin's noise floor. The remaining 11 are real and fixable:
- `Optional[callable]` → `Optional[Callable[..., None]]` (auth.py)
invalid-type-form on `callable` as a type expression. Added the
proper `typing.Callable` import. Two sites: on_pending in
poll_for_token, on_user_code in login_device_flow.
- Dropped three unused `# type: ignore` comments on
hermes_constants / hermes_cli.config imports — ty can resolve
those modules fine, the comments were dead.
- _supervise_sidecar(proc) widened `proc.stdout` from
`IO[Any] | None` to a narrowed local after an early `is None`
guard. Defensive against subprocesses launched without
stdout=PIPE.
- cli.py _cmd_setup: dropped the `has_existing_project = bool(...)`
intermediate, did the narrowing inline with `if existing_id and
existing_secret:` so ty can see project_id/project_secret are
non-None when create_user is called.
- test_inbound.py: replaced three `adapter.handle_message =
fake_handle # type: ignore[assignment]` with
`monkeypatch.setattr(adapter, 'handle_message', fake_handle)`.
Same behavior, no type-ignore, and the monkeypatch reverts
cleanly between tests.
Validation:
ty check plugins/platforms/photon/ tests/plugins/platforms/photon/
→ All checks passed!
tests/plugins/platforms/photon/ → 26/26 pass
py_compile clean
Windows footgun checker → 0 footguns
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
