aefffb2fd9 feat: add a photo to the album from the chat, tagged, stripped and verified
Some checks are pending
CI / check (push) Waiting to run
Send a photo captioned "!add_photo alfa wakacje" in one of the album's own
groups and it lands in the pack tagged with both, retrievable through !alfa
and the new !losowe immediately -- no restart, and no tagger session on the PC.
A label matching nobody becomes a custom tag, and !losowe is the only door to
one, which is what keeps a live swap a *data* swap: it can never register a
trigger or widen a command's groups.

No typed label travels. Labels become pseudonym keys in a new registry
arg_resolver, at the dispatcher, before the line that logs the command name --
so no handler, journal entry, command_uses row or reply body ever holds a word
somebody typed. The reply is counts and pseudonyms: "dodano · p1: 4 · t1: 1".

Stripping is exiftool with a *positive* check on the output, never an exit
code. ffmpeg was tried first and fails silently on photos: given a JPEG with a
real APP1 Exif segment it returned a byte-identical file, GPS intact, exit 0.
The surviving-tag allowlist is per tag *name* rather than per group, because
measurement showed a group-level "must be empty" rule rejects every format
except JPEG -- a valid PNG always reports its IHDR, an MP4 some fifty QuickTime
tags that are the container itself. Codec configuration (CompressorName,
VendorID, the HEVC parameter set) is on the list by decision: CompressorName
lives in the avc1 sample description and exiftool cannot write it at all, so
the alternative was refusing every video and every iPhone HEIC. Location and
identity tags are still refused, and the e2e run re-reads the stored files to
prove a QuickTime geotag did not survive.

.webm and .svg stay on the format allowlist and are stored *unstripped*:
exiftool 13.55 can write neither, and its SVG reader does not even surface
<metadata>. That is a deliberate, documented hole, not an oversight.

Two things this had to defuse along the way:
- personal_data_sources now reads custom.json, so "!add_photo kot <photo>"
  would have outlawed the word "kot" and refused every future commit, fixable
  only by hand-editing an album the committer cannot see. Minting now refuses
  a word that is already a command, and the gate subtracts the repo's own
  alias vocabulary from custom labels only -- curated people.json names are
  never excused.
- signal_bot/external.py is now the single subprocess site in the repository,
  so ruff's S603 needs exactly one scoped per-file-ignore instead of one per
  module that shells out. A test asserts nothing else imports subprocess.

A failed add changes nothing: media and the three manifests are written, the
album is reloaded, and only a load that succeeds is published; a load that
fails rolls all four back and keeps serving the pack that was already working,
without raising -- Restart=always would turn a ConfigError into a loop.

977 tests, 100% branch coverage, no omits and no suppressions. scripts/e2e.sh
gains 8 scenarios driven against the real exiftool on media generated at run
time, and asserts the invariants a reply cannot: that a refused upload is not
stored, that a message with no attachment leaves custom.json byte-identical,
and that signal-cli's own copy of every ingested attachment is gone.

Closes TODO-add-photo.md.

d5c63b423b feat: refuse to look healthy while deaf, and heal the container by itself
Today the bot was up, healthy and answering nothing for three hours. A host
firewall change (fixed in testsAndMisc 334c0cd9) cut every Docker container
off the internet; signal-cli lost Signal and reconnected in a loop from
15:32:50 onward. Nothing noticed:

  - the container's own healthcheck answered 204
  - /v1/groups answered 200 out of local state, so discovery saw no change
  - the bot's WebSocket to the container stayed OPEN, so the transport's
    reconnect logic never fired
  - /healthz answered {"status": "ok"} the entire time

The only symptom was silence, which is also what a quiet evening looks like.

signal_bot/liveness.py asks the one question that cannot be answered from a
cache -- GET /v1/devices, which needs a live round trip -- but only after
SILENCE_SECONDS (120) with no frame of any kind, so a busy group costs
nothing and an idle one costs one request per window. Three consecutive
failures and /healthz answers 503 with the reason. Verified end to end in
scripts/e2e.sh against the real process: 503 after 84s with the fake's
connection cut, back to 200 on its own 30s after restoring it.

scripts/signal_api_watchdog.sh + a two-minute user timer do the recovery the
bot cannot do for itself, since a wedged bot cannot restart the container it
depends on. Two tiers, so the steady state costs no Signal round trip at
all: the bot's own /healthz first, the authenticated probe only when that is
not 200. It stops after 3 restarts in 6 hours and escalates instead -- a
deregistered account or a blocked network is not fixable by restarting, and
a restart loop would hide it. Its own bash suite stubs curl and docker and
drives every branch including the give-up cap.

signal_bot/trust.py answers the other half: TRUSTED_INVITERS decides who may
put this bot in a group. The gate sits in GroupDirectory._permitted, which
both _join_pending and _adopt already route through -- gating only invites
would gate the door nobody uses, since prime_profile.sh exists precisely so
that an add becomes a direct join. Evidence is either the group-update
envelope, which is the only frame naming an inviter, or a trusted identity
being a full member in the listing. A refusal is logged once, with that
group's members, so the operator can see which string to add.

verify_allowlist moved to membership.py to keep discovery.py under the
250-line gate; it was already the module that owns MembershipError.

Verified live, by stopping the container by hand and touching nothing else:

  18:54:35  docker stop signal-api
  18:56:36  liveness: failure 1 of 3 after 123s of silence
  18:57:36  failure 3 of 3 -> /healthz answers 503 from 18:57:45
  18:58:18  watchdog: probe failed (1/2)
  19:00:28  watchdog: probe failed (2/2) -> docker restart signal-api
  19:00:36  liveness: receive path recovered after 8 failed probe(s)
  19:01:13  watchdog: signal-api is back

Six minutes, unattended, against three hours of silence this afternoon. All
four real groups are still adopted with TRUSTED_INVITERS=+48123456789 set,
and no group was refused.

b48c945d89 feat: make the bot actually reply on Signal, and gate every way it went silent
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.
