Let the operator add aliases from the Commands tab
A custom alias is data the command table is built from, so it cannot be a live switch like the ones already on the tab. Instead the management page writes aliases_custom.json in the bot's state directory and then asks the bot to reload, in one step: whenever the answer is anything but `reloaded` -- a word another command has, a name no command has, a bot still connecting -- the file is restored byte for byte and the bot's own reason is shown next to the field. What is on disk is therefore always what the bot serves, and a typo cannot sit in the file poisoning every later reload. The registry appends the operator's words to the shipped list at registration, which keeps `!pomoc` on the shipped spelling and routes the new words through the same clash check as aliases.json. An alias for a name no command has fails the whole build (ConfigError -> `kept`), because a silently ignored entry is how a file drifts. The tagger treats custom aliases as reserved words too, so a person cannot be given one. registry.py crossed the 250-line cap and now re-exports the record and the error types from command.py; the bot's state directory lookup, previously duplicated in pack.py and the suggestions export, is state_dir.py. Proven end to end: !e2ekot is unknown, the file is written and reload.sh runs, !e2ekot posts a cat, a file naming a command that does not exist is refused with 409 and the previous table still answers.

feat: a word the bot does not know gets an answer, and gets kept
An unrecognised "!word" was dropped in silence, which made a typo
indistinguishable from the bot being down and threw away the best available
list of commands worth writing. Three things now happen at the one place in
dispatcher.py that used to be a bare `return`.
A near miss is corrected -- "!cta" asks whether you meant "!kot". The
distance is optimal string alignment rather than difflib's ratio: a
transposition is the typo people actually make, it costs one edit here, and
it shreds the matching blocks a ratio counts ("!cta"/"!cat" scores 0.75 but
"!cta"/"!kot" scores 0.50, so no cutoff separates them on principle).
A word with no near miss points at !zaproponuj, which files an idea from
inside the group. Either way the word and the message are recorded, and the
management page grows an Ideas tab that lists them.
Three things stay silent, each for its own reason. "!kot ladny" is a real
trigger with words after it and always has been silent. "!!" is punctuation.
And a command claimed in some *other* group is neither answered nor recorded
-- the album's triggers are real people's names, and pack_scoping.yaml says
it out loud: a refusal would itself announce that the album exists. The
existence check is therefore global, which is what pack_add already asks.
Measured rather than guessed, against the shipped aliases.json:
- a minimum candidate length, because "!ja" is one edit from ~40 of the 676
two-letter words somebody could type; 69 of them got a suggestion before
the rule and 18 after.
- the two-edit budget starts at six characters, not five. At five it put
four pairs of *different* commands within reach of each other --
!pies/!popes, !days/!cats, !dzis/!dni, !mnie/!dni -- and costs nothing to
give up, because every real typo this was written for is one edit away.
test_no_two_commands_are_within_reach_of_each_other fails if a future
alias reopens the gap.
Both new tables are keyed on the envelope's own sent_at_ms, never the wall
clock: signal-cli replays undelivered frames on reconnect, and a clock-keyed
table collects a duplicate row per reconnect instead of ignoring one.
The branch is gated on should_count -- which excludes the bot's own envelope,
and that is the loop guard, since handle() checks is_own nowhere else -- and
wrapped in its own try/except, because it runs above the one that wraps a
handler and Bot.listen has no exception handling of its own.
Suggestions live in SQLite, not in a tracked file, and the export goes to the
state directory. check_personal_data learns the names it refuses from the
live database, so it catches a name somebody has typed and cannot catch a
misspelling of one -- and an unrecognised-command corpus is made of
misspellings. A group-writable file in a public tree is both a leak and a
wedge. The export therefore carries
deliberate !zaproponuj notes in full and unrecognised words as counts only;
bodies stay on the loopback-only page.
Verified on the live bot: restarted, both tables created with every existing
row count unchanged, !cta and !zaproponuj !pogoda delivered through
/_selftest, both rows read back out of the live database, and the journal
names neither the word nor the body.

feat: the management backend, absorbing the tagger
A second process rather than more routes on the bot's own app. This one can rewrite .env, and the bot's port already serves /_selftest, which posts for real into a real group; keeping them apart means the surface that can reconfigure the bot only listens while somebody has the page open. The tagger's seven routes move here unchanged, out of tool/ and into the coverage gate -- which is the reason an unconditional ImportError once sat in tagger.py through two releases. The media route is still indexed by integer, and that is not a style choice: a filename from a client is a path, and the directory holds private photographs. FastAPI refuses a name with 422 before the handler runs, which the tests assert. guard.py is the part that was not asked for. Binding to loopback stops the network, not the browser already running on this machine, and two attacks reach a loopback port from an ordinary web page: a cross-origin form, which can only send urlencoded, multipart or plain text, so requiring application/json refuses it with no token to keep; and DNS rebinding, whose request still carries the attacker's hostname in Host. Forty lines instead of authentication, which is the right trade for something started by hand and stopped again a few minutes later. assets.py branches on whether the page has been built, because StaticFiles raises at construction on a missing directory -- mounting it unconditionally would take the app down on a fresh clone, and in CI, where pytest never runs pnpm build. Both branches are tested; "not built" answers with the command. The container restart goes through signal_bot.external, wrapped in asyncio.to_thread: it is synchronous with a 60s default, and blocking the loop would freeze the page showing the restart. 100% branch coverage across all eleven modules, no omits, no pragmas.
