First live reply, as its own registered account. `!cat` and `!dog` from the
phone return images -- verified in the production shape (the bot *invited to
an already-existing group*) and under a systemd user unit.
Four failures, each of which left the bot looking perfectly healthy:
- Invited is not joined. Signal only adds an account outright if the adder
holds its profile key; with no profile the add becomes a pending invite,
and signal-cli cannot accept one addressed to a phone number ("Cannot find
service ID for self"). Group listed, websocket up, /healthz OK, zero
messages. register_bot.sh now sets the profile *before* the add, and
startup refuses on `member: false`.
- MODE=json-rpc-native is a GraalVM build with no AWT: text sends work,
every attachment 400s with "Can't load library: awt". Both mode guards now
demand exactly json-rpc, and start_container replaces a wrong-mode
container instead of reusing it.
- The API spells one group two ways -- /v1/groups returns `group.<base64>`,
envelopes carry what that decodes to -- so the scoping gate rejected the
bot's own group. e2e.sh now models both spellings; reverting the fix fails
4 scenarios, which is why the offline suite missed it before.
- BIND_PORT in .env was dead: __main__ read os.getenv before anything loaded
a .env. The bind address comes from Config now.
A taken port used to be uvicorn logging the collision and exiting 0, which
every supervisor reads as success. portcheck.py refuses to start, exits
non-zero, and names the holder by reading /proc directly -- no subprocess, no
PATH assumptions, testable against a fake proc tree. Default port is 8137:
not 8000, and below the ephemeral range so the kernel cannot take it.
The bot now runs as signal-bot.service (Restart=always, linger checked rather
than assumed, StartLimitBurst so a config error fails visibly instead of
looping). Verified by SIGKILL and by re-running a command under the unit.
100% branch coverage, 230 tests, all gates green.

Shelter cannot work on this phone, and it would not have helped anyway.
It cannot work: setting a Device Owner makes Android enable
no_add_managed_profile, no_add_private_profile and no_add_clone_profile on
every user, which kills Shelter, Island, Private Space and app cloning
alike. Verified on-device rather than inferred -- `pm create-user
--profileOf 0 --managed` returns "Cannot add user: no_add_managed_profile is
enabled". This is the Android 11 COMP deprecation, enforced in three places
in DevicePolicyManagerService and unchanged through Android 16.
It would not have helped: a second Signal *app* is not a second Signal
*account*. Every account needs its own phone number, so the second number
was always the real requirement -- and once you have one, signal-cli can
register it as a PRIMARY device with no phone app, no QR scan and no work
profile at all. That is strictly better than both the linked-device setup
and the Shelter plan: the bot cannot read personal DMs and never posts as
the account owner.
scripts/register_bot.sh drives that flow. It gates on signal-cli >= 0.14.7
rather than hoping: stable container tag 0.100 bundles 0.14.5, and on
2026-03-06 Signal made the post-quantum ratchet mandatory and de-registered
every account whose client lacked it -- a stale client is how a bot dies
silently months later. Verified that the recommended CI tag really does
bundle 0.14.7 instead of assuming it.
Rehearsed offline, not written blind. fake_signal grew /v1/accounts,
/v1/register/{number}, /v1/register/{number}/verify/{token} and
/v1/groups/{number}, so the whole runbook including every error path
(missing captcha, stray verify, wrong code, unregistered number, empty group
list, out-of-range and non-numeric picks) runs against the fake. The picker
was proven to resolve the group the user actually pointed at.
Prompts now read from $SIGNAL_TTY instead of /dev/tty directly. A hard-coded
/dev/tty made the interactive path untestable without a real terminal; the
seam is the same idea as the injected clock and transport on the Python side,
and is what let the picker be rehearsed at all.
live_smoke.sh and register_bot.sh share scripts/lib_signal.sh so the two
cannot drift, and shellcheck now runs with -x so the sourced lib is actually
linted from its callers.
201 tests, 100% branch coverage, all 23 gates green.

CI failed on shellcheck where the local hook passed: the runner's shellcheck
reports SC2015 (`A && B || C` is not if-then-else) and mine did not. Both now
run with --severity=style so a version skew cannot pass locally and fail in
CI. The cleanup traps are plain ifs, which is what the finding was about --
`kill` on an already-dead pid makes B fail and C run while A is true.
live_smoke.sh choose_group had two bugs that only surface when it is actually
run, neither reachable from the offline suite:
- it fetched /v1/groups twice, once to display and once to resolve the picked
index, so an unstable order would hand back a different group than the one
shown. Fetched once into a variable now.
- `read -r -p` wrote its prompt to stdout, which the caller captures with
$(...), so the prompt text would have been swallowed into the group id.
Prompt and listing both go to stderr; stdout carries only the id.
Also validates that the pick is a number and in range.

The bot did not work. `run.sh` started a FastAPI app whose
`@app.on_event("startup")` awaited `asyncio.gather()` on two infinite
tasks, so uvicorn never finished starting up and no HTTP was ever served;
the readme's `python main.py` was a no-op with no `__main__` block and no
`uvicorn.run()` call. All three CI workflows were red, one referencing an
`environment.yml` that does not exist.
Rewritten as a package behind an injectable transport seam, which is what
makes the offline environment possible.
Bugs fixed:
- startup deadlock: lifespan spawns the loops instead of awaiting them
- sticker filter read dataMessage.sticker even on syncMessage envelopes, so
the account's own stickers were never filtered (e038772, 53028cc, 07fa90d,
2416cef all fought this symptom)
- no websocket reconnect: a container restart killed the bot silently
- blocking `requests` inside async functions stalled the event loop
- every counted message DMed the whole tally to the bot itself
- images were written to CWD under a filename taken from the remote URL
- one global 10s cooldown shared across all users and commands
- dead code: RECEIVE_URL, get_attachments (no call site), USER_MESSAGE_COUNT
- .env.sample declared PRIMARY/SECONDARY_PHONE_NUMBER and MODE, none read
Scoping is now an enforced invariant. A linked device receives every DM and
every group on the account; GROUP_ID was the only thing narrowing that and
defaulted to "". Config refuses to start unscoped, direct messages are
dropped explicitly rather than by a falsy check, and a scenario asserts that
DMs and other groups produce zero outbound messages.
Offline environment: fake_signal/ serves the real protocol surface, so the
unmodified bot connects to it by pointing API_BASE_URL at it. scripts/e2e.sh
boots both, replays 7 scenarios and exits non-zero on mismatch. A local
Signal server is not achievable (signal-cli compiles its endpoints and trust
store in; Signal-Server needs FoundationDB), so faking this boundary is the
only way to test every feature without an account.
Transport pinned to bbernhard/signal-cli-rest-api:0.100 with
MODE=json-rpc-native. The readme pinned 0.167-dev; the dev tag series counts
separately, so that was older than 0.100, not newer. /v1/receive is only a
WebSocket in a json-rpc mode, so the mode is verified at startup.
Repo standards: ruff select=ALL, mypy --strict, 189 tests at 100% branch
coverage, 250-line cap, exact pins at newest stable, shared gates delegated
to ~/utils, one CI workflow replacing three red ones. No noqa, no
type: ignore, no coverage omits anywhere.
