Bot.listen awaited every frame to completion, so one Commons fetch or one
attachment upload held up every text reply behind it (DOCS-latency.md).
Each frame now runs in its own task, never more than LIMIT at once; the
reader waits for a slot before spawning, so a burst applies back-pressure
at the websocket instead of fanning out upstream. One person's commands
stay serialised (user_lock.py): two quick !kot would otherwise both pass
the cooldown gate before either recorded a use.
Every served command reports its timings split into the bot's own time
and everybody else's (served.py); /_selftest carries that block and
tool/latency.py holds own_ms to 100 ms at p95, with the command's
cooldown switched off for the run and put back afterwards.

One row per live command on a new Commands tab of the management page,
each with an on/off switch, an optional "off until" moment and a cooldown
that overrides the bot's default for that command alone. Every switch is
live: the bot keeps them in its own SQLite (command_settings, a permanent
table) and reads the row on every attempt, so nothing goes through
/_reload and nothing restarts.
A command that is off answers "BEEP BOOP !kot WYŁĄCZONE." (with "DO HH:MM"
for a timed switch) rather than going quiet, so nobody reports it broken;
the refusal is filed as refused_off, which the analytics count with the
other refusals, and it neither starts the cooldown nor counts as a use.
The bot grows GET /_commands and PUT /_commands/{name}; the management app
proxies them under /api/commands and passes the bot's 404/503 through
unwrapped. !cisza and !odcisz carry no cooldown and the page says so
instead of accepting a number the bot would ignore (test_wiring_ungated
keeps that set honest against the real table).
Proven end to end: scripts/e2e.sh now brackets a PUT with switch_off.yaml
and switch_on.yaml, the same actor refused and then served, with no reload
between them. Also bumps vitest and @vitest/coverage-v8 to 5.0.0 and
@types/react-dom to 19.2.7, which the freshness gate asked for.

The registry used to be built once, inline in build_bot, so every change to
the data behind it -- a person tagged in the web UI, an alias, soon a command
switched off from the management page -- meant restarting the unit. That is
cheap and lossless, but it is a deploy step somebody has to remember, and a
21:37 report can land in the middle of it.
Now the registration sequence lives in wiring.build_registry, and
RegistryHolder runs it again on POST /_reload: the new table is built whole
and swapped in with one assignment, never patched in place, so a duplicate
trigger is found before anything the dispatcher reads has changed. Bad data
(ConfigError, DuplicateTriggerError) keeps the previous table and answers
409 with the reason; a programming error still surfaces as a 500.
scripts/reload.sh wraps it, with --code for the restart a Python change
needs, and an optional command to type in testbot so "reloaded" means
"answered". No Python hot-reload on purpose.
The loader change is what makes deploying this safe: two rows in the live
tags.json name files that are no longer in media/, and load_pack refused
them, so the next restart would have looped on ConfigError. A stale tag is
drift in a file a page edits mid-session, not a broken album -- it is now
skipped with a warning naming it. A tag that reaches outside the album is
still refused. pack_load.py split at the 250-line cap; pack_tags.py is the
half whose checks are not all fatal.
Proven offline in scripts/e2e.sh: !delta is unknown, a fifth person is
tagged into the synthetic pack, scripts/reload.sh runs, and the same
process posts delta's photo.

Two things the first live run found, neither of which any test could have.
**exiftool was invisible to the unit.** Arch's perl-image-exiftool installs to
/usr/bin/vendor_perl/exiftool. That is on an interactive shell's PATH, because
perl's profile.d puts it there, and it is *not* on a systemd user unit's, whose
default is "/usr/local/bin:/usr/bin". So shutil.which found it in every test
and in every shell, and the first real !add_photo under the unit answered
"exiftool is not installed; refusing to store .jpg" -- with exiftool plainly
installed. media_strip.locate() now tries PATH and then the known install
locations, and install_service.sh verifies the result through the bot's own
resolver under the unit's PATH rather than through `command -v`, which answers
for the wrong shell. Fixing the lookup rather than setting PATH in the unit:
the latter is a note somebody has to remember on the next machine.
The absent-exiftool test had to blind *both* lookups to keep covering its
branch -- on a machine that has the package the fallback finds it, which is
precisely how the gap survived.
**The self-test could not carry a photo.** Signal never delivers an account
its own sends: measured against the live container, a single-device account
gets no sync copy either, and a sent attachment is not added to the container's
attachment store (only inbound ones are). So !add_photo could not be exercised
the way every other command is. selftest.build_frame and POST /_selftest now
take attachment ids that the container's store already holds, so the handler
fetches them back over the real GET /v1/attachments/{id} -- the ingest path
under test is the live one, not a hand-fed buffer. Still fail-closed on
SELFTEST_GROUPS.
Verified live, against real Signal and the real container, in the testbot
group, on a throwaway album scoped to that group so the private one was
neither read nor written:
- a geotagged JPEG (GPS + Make) went in as "!dodaj alfa wakacjelive"
- the stored file reports zero non-structural tags, and neither the GPS
marker nor the Make string survives in its bytes
- GET /v1/attachments/<id> now 404s and the file is gone from disk, so the
second copy really is deleted
- the typed label appears zero times in the journal
- !losowe wakacjelive, !alfa and an unknown label all answered without error

"Wersja 0.1.7 «Callistus I»" told nobody whether Callistus was the
fifteenth pope or the hundredth, and the changelog was the one place the
ladder is actually read. pope_line() derives both facts from popes.json --
the ordinal, and the `reign` string exactly as the table spells it, so the
one reigning pope keeps his single year instead of being padded into a
range he never had.
It appears in all four places a version is named: the group announcement
(header and every block of a backlog), each section of DOCS-changelog.md,
/healthz, and the !papiez caption, which now describes the release's pope
in the same sentence it uses for every other one.
The changelog's copy is checked rather than trusted, like the heading name
already was: a test walks the raw file and compares each line against
popes.json, so a hand-edited ordinal fails here instead of in a group.

The tally was one integer per person, deleted after each post. Nothing
dated survived it, so weeks, months, records, streaks and weekday
averages were all unanswerable. This replaces it with an append-only
per-message log holding metadata only -- never a message body -- and
rebuilds the nightly report on top.
What changes for the group: a photo posted without a caption now counts
(it was worth zero), stickers count, the bot's own messages no longer
do, people who said nothing appear with a 0, and the report covers the
previous full calendar day in Europe/Warsaw instead of "since the last
post" -- which used to merge two days whenever a group went quiet.
Notable decisions, each with the trap it avoids:
- Events and people are PERMANENT_TABLES: neither forget_group nor a
future SCHEMA_VERSION bump may drop them. Both paths used to cost a
day's counter and would now cost the entire history, and forget_group
fires on a listing that merely omits members.
- is_own comes from which envelope branch carried the payload, not from
comparing identities. The account is spelled as a uuid on some frames
and a +E.164 number on others, so any comparison misses one of them.
- The roster is stashed in refresh(), not _adopt(), which returns early
once the watched set stops changing -- i.e. always, in the steady
state.
- The roster matches on uuid OR number because /v1/groups spells kuhy as
+48123456789 while his messages carry an ACI uuid. Joining on uuid
alone would have listed him twice every night, once with 0.
- Members whose display name we have never seen are counted, not named:
their only spellings are a uuid or a phone number.
- (group, uuid, sent_at_ms) is the primary key, so a websocket
redelivery after a reconnect cannot inflate the counts.
- Days come from a stored Warsaw date string, never a timestamp range:
2026-03-29 is 23 hours long and 2026-10-25 is 25.
- Polish number agreement is a real rule with a 12-14 exception, so
"44 znaki" and "45 znaków" are both spelled correctly.
config.py and startup.py were two lines under the 250-line cap and both
had to grow, so config_env and startup_retry come out of them first, as
pure moves.

Adds !papież / !papiez / !pope: a random pope as a photo, captioned with his
Latin name, reign and pl.wikipedia link. popes.json already carried a Commons
portrait filename for all 267 and nothing had ever consumed it.
The Latin name comes from the Latin column of Poczet papieży, not from the
la.wikipedia sitelink. The sitelink resolved for all 267 and was still wrong:
la.wikipedia numbers several popes differently, so #154 came out as
"Stefan IX — Stephanus X" in a single caption, which reads as an off-by-one.
The table's own column says "Stephanus Nonus" and cannot disagree with the
name beside it. LATIN_OVERRIDES ships empty; it is a tripwire, not a backlog.
Portraits are cached on disk under CacheDirectory=signal-bot, named from the
ordinal so no upstream string ever reaches a path, and bounded at 267 entries
so nothing needs evicting. Verified that CacheDirectory wins against
ProtectHome=read-only before relying on it.
Also adds POST /_selftest and scripts/selftest.sh. Signal never delivers an
account its own sends, so no command has ever been exercised end-to-end
without asking a human to type it. This injects a real frame into the live
dispatcher; it is loopback-only and refuses any group not in SELFTEST_GROUPS,
which is empty by default.
Verified against the real endpoints, not just the fake: 267/267 portraits
resolve on Commons, regeneration is byte-identical on every previously
shipped field, and !papież was driven 7 times through the live dispatcher in
testbot, returning distinct popes.

Release n is pope n, so the version is a fact about the ordinal rather than a
judgement about the size of a change. The constraint that fixes the scheme is
Jan Pawel II at 2.13.7: eight patches per minor with majors opening at ordinals
33 and 153 gives (264 - 153) = 13 * 8 + 7 exactly, and both earlier majors
happen to divide evenly by eight too, so no bracket needs a fudge factor. The
anchors are not arbitrary -- 33 is Sylwester I, pope through the Edict of Milan
and Nicaea, and 153 is Wiktor II, the first pope elected after the 1054 schism.
popes.json is scraped by tool/gen_popes.py rather than recalled, because
antipopes, Benedykt IX's three separate reigns and the Stefan II question all
shift the count and being wrong by one moves Jan Pawel II off 2.13.7 silently.
The generator refuses to write a list that is not 267 contiguous entries with
Jan Pawel II at 264. A second, independent parse of the same page agreed on
every ordinal, which is the only reason to believe either.
On startup each watched group is told about the releases it has not seen. A
group with no record has seen none of them, so the first announcement starts at
0.0.0 "Swiety Piotr Apostol" rather than skipping to whatever is current --
watching the ladder start at Peter is the point of naming releases after popes.
A group added years from now would otherwise be handed the whole backlog, so
the message is capped at ten releases and says how many it left out. The
version is recorded before the message is sent: with Restart=always and
RestartSec=5, a crash between the two would re-announce on every restart, and a
missed announcement is far cheaper than a looping one.
DOCS-changelog.md is the single source -- the bot parses it, so there is no
second machine-readable copy to drift. It is DOCS-, not CHANGELOG.md, because
the md-naming gate allows four namespaces and that is not one of them.
Deliberately NOT bumping SCHEMA_VERSION for the new group_meta table:
_apply_schema drops every table on a bump, so bumping to add a table would have
thrown away the live tallies to gain nothing. Verified against the real
database -- group_meta appeared and all four counts survived the restart.
The schema moves to its own module so store.py stays under the 250-line cap,
and /healthz now names the build, because there was previously no way to ask a
running bot which version it is.

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.

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.

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.
