Maintainer rework of #45580 (issue #54036) on top of the contributor's
cherry-pick, which targeted spectrum-ts 3.1.0 while main pins 8.0.0:
Sidecar (primary detection, new):
- stream-staleness.mjs: pure decision rules, executable under node.
* classifyProbeRejection: only a not-found-shaped rejection of the
synthetic-id read counts as a completed round-trip (ALIVE); any other
rejection is INCONCLUSIVE — never alive. The original /probe treated
ANY rejection as alive, which was too loose.
* shouldProbe: probe only after 10+ min of stream silence (configurable
via PHOTON_STREAM_SILENCE_PROBE_MS; <=0 disables) with a cooldown.
* isZombieSuspect: zombie only on silence past threshold AND a
probe-proven live channel. Silence alone NEVER degrades (shared lines
can be quiet for hours); inconclusive probes NEVER degrade (network
may be down — the iterator will throw and the re-subscribe loop
recovers on its own).
- index.mjs: track last inbound-iterator yield (noteInboundYield), run a
30s watchdog tick, and on a confirmed zombie feed markStreamDegraded ->
the existing exit-75 restart path. /healthz gains a stream.staleness
block (silentForMs, threshold, lastProbeOutcome, zombieSuspected).
/probe reworked to strict semantics: 200 only on a proven round-trip,
503 with outcome hung|inconclusive otherwise.
Adapter (second layer, reworked):
- _probe_once returns tri-state alive|hung|inconclusive; only a hung
sidecar HTTP call counts toward the respawn counter — inconclusive
resets nothing and triggers nothing.
- default probe_interval_seconds 60 -> 600 (conservative; avoid restart
storms on quiet lines).
- _monitor_sidecar_health surfaces zombieSuspected from /healthz as a
warning; the fatal UPSTREAM_STREAM_DEGRADED path is unchanged and fires
when the sidecar escalates.
Tests: test_zombie_stream_watchdog.py executes the real node decision
module and drives the adapter against mocked /healthz responses;
test_presence_watchdog.py updated for the tri-state probe.
Also adds contributor mappings for nickkarhan (#53283) and vaibhavjnf
(#45580).
Follow-up to the URL markdown fix: extract the /send builder decision into
sidecar/send-format.mjs and rewrite test_url_send_path.py to execute the real
module under node (format+text in -> chosen builder out) instead of regex-
grepping index.mjs source, which is a banned test pattern in this repo.
spectrum-ts's live-stream consumer (consumeLive in spectrum-ts 3.x) only
reconnects when its inbound async iterator throws or ends. A half-open
("zombie") gRPC socket — where the TCP connection stays ESTABLISHED but the
peer is gone (NAT idle-timeout, network blip, laptop sleep) — makes the
iterator hang forever: no error, no end. The SDK exposes no gRPC keepalive
knob (createClient takes only {address, tls, token}; grpc.keepalive_time_ms
defaults to -1 = pings off), so the inbound stream silently dies and stays
dead until the gateway is restarted. Symptom: the agent's iMessage line goes
"online but deaf" — Photon's cloud-side fallback answers users with "the agent
isn't online right now" and inbound never reaches the gateway.
Fix, entirely in the code we own (no SDK fork):
- Sidecar gains a POST /probe endpoint that drives a cheap unary read
(space.getMessage on a synthetic id) over the SAME gRPC channel the inbound
stream uses. A live channel round-trips in ms (server returns not-found,
which is success for liveness); a zombie hangs. It sends nothing to any user
and creates no chat (space.get is local in shared/dedicated mode; only the
message read touches the wire).
- The adapter runs a presence watchdog: it probes on an interval, skips the
probe when natural inbound traffic already proved liveness within the
window, and after N consecutive failed probes respawns the sidecar — a fresh
Spectrum() re-subscribes the stream and re-registers presence. Successful
probes double as application-level keepalive, helping prevent the zombie
from forming at all. Respawn is lock-guarded against double-spawn and the
watchdog is torn down cleanly on disconnect.
Behavioural settings live in config.yaml (extra), bridged to env per the
.env-is-secrets-only convention:
probe_interval_seconds (60), probe_timeout_seconds (10),
probe_max_failures (3). A non-positive interval disables the watchdog.
Tests: tests/plugins/platforms/photon/test_presence_watchdog.py covers config
resolution, the disable switch, probe alive/dead(500)/timeout/no-client, the
core N-failures->one-respawn detection, success-resets-failures, stop-then-
start respawn ordering, and lock-guarding — all without spawning Node or
hitting the network.

imessage.effect.message crashed the sidecar at import against SDK stubs/
builds lacking the effect surface (caught by the patch-failure health test).
Optional-chain with {} fallback; /send-effect rejects cleanly instead.
Follow-up to the #48194 pick: it was written before #43665 landed and
re-added its own /send-poll sidecar route and poll import. Collapse the
duplicates:
- keep #43665's /send-poll route (>=2 trimmed string options) as the
single sidecar implementation; drop #48194's variant
- drop the duplicated poll import in the sidecar destructure
- make adapter.send_poll() a thin wrapper over _sidecar_send_poll(), the
one /send-poll client (shared with the poll-backed clarify path), and
align its validation to the sidecar's >=2-options contract
The `clarify` tool's multiple-choice prompts flattened to a numbered text
list on Photon/iMessage, even though iMessage has a native poll bubble and
spectrum-ts already exposes it via the `poll()` content builder. Two gaps
caused the flattening:
* Outbound: the sidecar only had `/send` (text); there was no way to send
a poll, so the base adapter's numbered-text fallback was used.
* Inbound: `normalizeContent()` handled only text/attachment/voice, so a
poll vote (`poll_option`) was dropped on the floor ("[Photon content
type not handled: poll_option]") and never resolved the clarify.
Fix, end to end:
* Sidecar: import `poll` from spectrum-ts; add a `/send-poll` route
(`space.send(poll(title, ...options))`); serialize inbound `poll_option`
(the vote: chosen title + selected bool) and `poll` content in
`normalizeContent()`.
* Adapter: override `send_clarify` — for choices, send a native poll via
`_sidecar_send_poll` and call `mark_awaiting_text` so the gateway's
existing pending-clarify text-intercept resolves the answer; open-ended
clarifies keep the plain-text path. Inbound `poll_option` selections are
dispatched as a plain-text MessageEvent carrying the chosen option
(deselections / empty votes are dropped). If the poll send fails (an
older sidecar without `/send-poll`, or a send error) it falls back to the
numbered-text clarify, so nothing regresses on a half-upgraded restart.
No new model tool, no new env var, no core change — the capability lives at
the platform edge. The poll vote reuses the existing clarify text-intercept
resolution path, so no new gateway resolution mechanism is introduced.
Tests: tests/plugins/platforms/photon/test_poll_clarify.py — inbound vote ->
choice text, deselection/empty-vote dropped, send_clarify sends a poll +
enables text-capture, open-ended stays text, and poll-failure falls back to
the text list. Full photon suite green.

Maintainer follow-up to the #51193 salvage:
- _send_with_retry: permanent classes (auth_or_config, target_not_allowed)
now short-circuit BEFORE the unconditional plain-text fallback resend,
including when a retry attempt surfaces one — no more double-sends of
permanently-failing requests.
- sidecar classifySidecarError: new structured code target_not_allowed for
Spectrum's 'Target not allowed for this project' AuthenticationError
(shared/free-tier lines cannot initiate outbound sends to new targets).
Classification applies to every handler sharing the catch-all
serverError path (/send, /send-attachment, /react, /typing, ...).
- _standalone_send now parses the structured error body too (it reads
sidecar responses independently of _sidecar_call) and returns
error_class/retryable alongside the message.
- target_not_allowed maps to a canonical user-facing message in both
paths; raw upstream error text never leaks through the structured code.
Closes the actionable halves of #50971, #51897, #52794.
Photon's Node sidecar intentionally hides raw handler exceptions, but the Python adapter still needs a safe failure class and retryability bit so delivery retries do not collapse into an opaque generic 500.
Constraint: Sidecar responses must not leak raw stack traces or private exception text
Rejected: Retry every internal sidecar error | masks permanent auth/config failures
Confidence: high
Scope-risk: narrow
Directive: Keep sidecar error text generic; extend safe error classes instead of exposing raw SDK failures

Problema
--------
Quando o npm install do sidecar Photon falhava, o Hermes descartava toda
evidencia e continuava normalmente - deixando o adapter de iMessage
silenciosamente ausente, sem nenhuma mensagem de erro acionavel.
Tres falhas independentes formavam o caminho de falha silenciosa:
1. check_requirements() sem logging
Cada branch de return False retornava sem emitir nenhum log. O core em
platform_registry.py so consome o bool de check_fn() e loga uma mensagem
generica com o install_hint - sem acesso ao motivo real da falha.
if not HTTPX_AVAILABLE: return False # sem log
if not shutil.which(node): return False # sem log
if not node_modules.exists: return False # sem log
2. node_modules/ parcialmente criado passava o guard (Risk 2)
npm cria node_modules/ antes de abortar em ENOSPC, timeout de rede ou
EACCES. O diretorio existia, check_requirements() retornava True (falso
positivo), o adapter era registrado, e o crash acontecia em runtime com
um erro de modulo ausente aparentemente nao relacionado ao setup.
3. stderr do npm descartado (Risk 3)
subprocess.run sem stderr=PIPE. O output de erro aparecia no terminal
durante o setup e sumia depois - diagnostico impossivel em CI/CD, Docker,
VPS headless, e qualquer reinstalacao posterior.
Correcoes
---------
adapter.py - check_requirements() agora loga por branch:
- httpx ausente -> logger.warning com nome do pacote
- node nao no PATH -> logger.warning com nome do binario e env var
- spectrum-ts ausente -> logger.debug com path do sidecar + ultimo erro npm
(DEBUG nao WARNING: estado normal pre-setup; check_fn() e chamado de
5 hot paths do core incluindo polling do /api/status)
adapter.py - content check em vez de existence check (Risk 2):
antes: if not (_SIDECAR_DIR / node_modules).exists()
depois: if not (_SIDECAR_DIR / node_modules / spectrum-ts).exists()
spectrum-ts e a unica dependencia do package.json. Checar sua presenca
garante que instalacao parcial/abortada e detectada no boot do gateway,
nao na primeira mensagem recebida via gRPC.
cli.py - stderr capturado e persistido (Risk 3):
subprocess.run passa agora stderr=subprocess.PIPE, text=True em ambas as
chamadas (npm ci e npm install fallback). O stderr capturado e:
- impresso em sys.stderr imediatamente (output visivel no terminal)
- persistido em _NPM_ERROR_LOG = sidecar/.photon-npm-error.log se
returncode != 0, limitado a 300 chars
- apagado de _NPM_ERROR_LOG se returncode == 0 (evita erro stale)
check_requirements() le _NPM_ERROR_LOG quando spectrum-ts esta ausente e
inclui o conteudo no DEBUG log - o erro do npm sobrevive ao terminal, ao
restart do gateway e a reinicializacao da maquina.
sidecar/.gitignore - adicionado node_modules/ e .photon-npm-error.log.
Isolamento - sem impacto no core:
- check_fn() continua retornando apenas bool; core nao e modificado
- Logging usa namespace plugins.platforms.photon.adapter, isolado de
gateway.* e hermes_cli.*
- Cada plugin tem seu proprio check_requirements() independente
- OSError no write/read de _NPM_ERROR_LOG e silenciado - nunca propaga
Testes - 24/24 passando:
test_check_requirements_risks.py (7 testes):
WARNING emitido quando httpx ausente
WARNING emitido quando node nao no PATH
DEBUG emitido (nao WARNING) quando spectrum-ts ausente, com path
node_modules/ vazio agora retorna False (Risk 2 resolvido)
_NPM_ERROR_LOG escrito no stderr do npm em falha
_NPM_ERROR_LOG apagado apos npm bem-sucedido
erro npm aparece no DEBUG log quando node_modules ausente
test_npm_error_log_regression.py (9 testes - vetores de falha da solucao):
return code contrato intacto (0 em sucesso, nao-zero em falha)
OSError no write do log silenciado, exit code ainda propagado
OSError no read do log silenciado, check_requirements() retorna False
stderr vazio nao cria arquivo de log
proc.stderr=None nao lanca AttributeError
log stale apagado apos reinstall bem-sucedido
DEBUG emitido mesmo sem log de erro (setup pela primeira vez)

Populate `reply_to_message_id`, `reply_to_text`, and
`reply_to_is_own_message` on reaction events so the gateway injects
`[Replying to your previous message: "..."]` when the agent receives
a tapback.
The sidecar now extracts a capped text preview from the hydrated
reaction target (plain text and mixed group messages; null for
attachment/voice-only targets), emitting it as `targetText` in the
NDJSON reaction payload. The Python adapter reads this field and sets
the reply correlation fields on the `MessageEvent`.
v8 made `richlink` outbound-only; inbound rich links now arrive as
plain `text`. Remove the `getBalloonBundleId`/`toRichlinkMessage`
branches from the iMessage mapper patch and update the fixture,
lockfile, and README accordingly.
Update the Photon platform plugin's Node.js sidecar from spectrum-ts
3.1.0 to 7.0.0, which splits the SDK into scoped `@spectrum-ts/*`
packages with `spectrum-ts` as the umbrella re-export.
- Bump exact pin in package.json/package-lock.json to 7.0.0
- Update mixed-attachments patch script to target the new
`@spectrum-ts/imessage/dist/index.js` path and tab-indented output
- Rewrite test fixture to match v7.x mapper shape (tab-indented,
`const ... = async` declarations, single-line builder calls) and
point at `@spectrum-ts/imessage/dist/index.js`
- Update README upgrade guide to document the v5 package split and
the postinstall patch validation step
- Update comments in cli.py and index.mjs to reference v5/v7 changes
spectrum-ts routes stream telemetry through @photon-ai/otel's createLogger,
which sends severity>=ERROR to console.error and WARN/INFO to console.log.
The two lines the health monitor keys off land on different channels:
log.error("stream persistently failing") -> console.error (caught), but
log.warn("stream interrupted; reconnecting") -> console.log (was missed).
The original interception patched console.error only, so the recovering->
degraded escalation counter never saw the interrupt bursts that are the
primary silent-inbound symptom. Verified live against spectrum-ts 3.1.0 +
@photon-ai/otel: 3 real log.warn('stream interrupted') calls now escalate
to degraded -> process.exit(75) -> adapter reconnect.
Adds a shared classifyStreamLog() fed by both console.error and console.log,
plus a regression test asserting both channels are intercepted.
* fix(photon): preserve text in mixed iMessage attachments
When an iMessage bubble carried both text and an attachment, spectrum-ts'
inbound mapper returned only buildAttachmentMessage(...), dropping the user's
typed text before Hermes could see it. The Photon adapter then had no 'group'
content path, so the text was lost entirely.
- adapter.py: handle a new 'group' content type that flattens text + attachment
items, preserving the typed text alongside cached media (extracted shared
_normalize_binary_payload helper).
- sidecar: emit 'group' content in normalizeContent, and ship
patch-spectrum-mixed-attachments.mjs which patches spectrum-ts' pinned mapper
(at npm postinstall AND at sidecar startup, so existing installs self-heal).
Windows robustness fixes on top of the original PR:
- The patcher's CLI guard used 'import.meta.url === file://${argv[1]}', which
never matches on Windows (file:/// + drive letter) — it silently no-opped.
Switched to pathToFileURL(argv[1]).href.
- The patcher matched \n-joined strings, so a CRLF checkout (Windows git
autocrlf) defeated every replacement. It now normalizes CRLF->LF for matching
and restores the original EOL style on write.

A hard gateway exit (crash, SIGKILL, supervisor restart) left the
detached Node sidecar running with a token the next gateway run doesn't
know, so it could never be told to /shutdown. Every replacement spawn
then died on EADDRINUSE, failing each 30→300s reconnect attempt while
the orphan kept consuming the inbound gRPC stream.
Two layers:
- Lifetime binding: the adapter now holds the sidecar's stdin as a
pipe, and the sidecar (PHOTON_SIDECAR_WATCH_STDIN=1) shuts down on
stdin EOF — fired by the OS on any parent death, including SIGKILL.
- Startup reaping: before spawning, the adapter probes the port and
terminates a stale listener, but only after verifying its command
line is a Photon sidecar; a foreign listener raises a clear error
instead of being signalled.

Pin spectrum-ts to exactly 3.0.0 (was ^1.18.0 plus an `npm install
spectrum-ts@latest` on every setup) so breaking SDK majors can't take
down fresh installs silently; `hermes photon setup` now runs `npm ci`.
Upgrade procedure documented in the README.
Migrate resolveSpace to the v3 namespace API: `im.space.create(phone)`
for DMs and `im.space.get(id)` for everything else — group spaces are
now rehydratable from their persisted id after a sidecar restart, which
v1 could not do.
Markdown: replies go out via the v3 `markdown()` builder (iMessage
renders natively; other Spectrum platforms degrade to plain text).
`PHOTON_MARKDOWN=false` reverts to the stripped plain-text path.
Reactions, behind PHOTON_REACTIONS (default off): lifecycle tapbacks
(👀 while processing, 👍/👎 on completion) via new sidecar /react and
/unreact endpoints with per-target reaction-handle tracking, and user
tapbacks on bot-sent messages routed to the agent as synthetic
`reaction:added:<emoji>` events.

* fix(photon): override transitive CVEs in the sidecar deps
`npm audit` flagged 7 high-severity transitive CVEs (protobufjs code injection
GHSA-66ff-xgx4-vchm + outdated @opentelemetry OTLP exporters) pulled in via
spectrum-ts -> @photon-ai/otel. npm's suggested fix downgrades spectrum-ts to a
version that targets the decommissioned spectrum host, so instead pin patched
versions via `overrides` (protobufjs 8.6.1, @opentelemetry/* 0.218.0) without
touching spectrum-ts. `npm audit` -> 0; spectrum-ts + provider still import.
* fix(photon): harden the sidecar bridge + bound the dedup cache
- constant-time sidecar control-token comparison (was `!==`, timing-attackable).
- cap the control-channel request body (2 MiB) so a compromised local peer can't
OOM the sidecar.
- wrap the inbound gRPC stream consumer in a re-subscribe loop with capped
exponential backoff + jitter — if the async iterator throws/ends it would
otherwise stop inbound forever (the adapter dedupes any replay).
- add an unhandledRejection handler so a stray rejection logs instead of killing
the process.
- dedup cache (adapter) was a true bounded LRU only for expired entries; a burst
of unique ids within the window grew it without limit. Evict oldest at the cap.

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.
Drop `replyTo` from all outbound send paths and update the `/typing`
endpoint to use the documented `typing("start" | "stop")` content
builder. Adds a `stop_typing` method on the adapter to pair with
`send_typing`.
Replace raw `{ replyTo }` send options with the `spectrumReply` content
builder from spectrum-ts, which is the correct API for threading
replies.
Adds `maybeReplyContent` helper with graceful fallback to normal send
when
the reply target cannot be resolved.
Allow PHOTON_HOME_CHANNEL to accept a bare E.164 phone number or a
`any;-;+1...` DM chat GUID in addition to a Spectrum space id. Inbound
DM spaces are cached so replies resolve without a second SDK lookup,
and `photon` is added to _PHONE_PLATFORMS so send_message treats E.164
strings as explicit targets rather than falling through to channel-name
resolution.
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.
CI red on three blocking checks; all addressed:
1. Windows footguns: os.killpg() flagged as POSIX-only despite the
sys.platform != 'win32' guard. Static scanner doesn't see flow.
Added the documented '# windows-footgun: ok' suppression.
2. test (3): tests/plugins/platforms/photon/__init__.py shadowed the
real plugin's __init__.py because test_plugin_platform_interface.py
looks at PROJECT_ROOT/plugins/platforms/<name>/__init__.py with
PROJECT_ROOT=tests/ (pre-existing bug in that test, made visible
by the new test directory layout). Dropping the empty test
__init__.py restores the prior NOTSET parametrize behavior.
3. CodeQL (7 alerts in new code):
- cli.py: stop printing the first 8 chars of the bearer token after
login — even prefixes are partial credentials.
- cli.py: stop printing the first 8 chars of project_secret after
setup, same reason.
- cli.py 'hermes photon webhook register': stop dumping the raw
register-webhook response (contained signingSecret) and stop
echoing PHOTON_WEBHOOK_SECRET to stdout. Write it directly to
~/.hermes/.env (0o600), preserving existing entries; fall back
to manual instructions only if the file write fails. Photon
still only returns the secret once; this just doesn't put it
in scrollback / shell history.
- cli.py setup + status: rename project_id/project_secret/token
locals to has_* booleans before printing, breaking CodeQL's
taint flow through f-string interpolations. Drop diagnostic
prints of phone / assignedPhoneNumber that flagged as
'sensitive data' false positives.
- sidecar/index.mjs: stop returning the raw error message
(potentially containing stack trace) in HTTP 500 responses;
supervisor logs the real error to stderr, client only sees
a generic 'internal sidecar error'.
Validation:
- scripts/check-windows-footguns.py --all → 0 footguns (518 files)
- tests/plugins/platforms/photon/ → 22/22 pass
- tests/gateway/test_plugin_platform_interface.py → 7/7 pass, collects
NOTSET (matches pre-PR state)
- tests/gateway/test_platform_registry.py → 50/50 pass
- node --check sidecar/index.mjs clean
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
