Krzysztof kuhy Rudnicki 08599e6056 feat: two commands that answer with somebody else's work
!sztuka posts a work of art, skewed 60% Polish; !wiersz posts one short
public-domain Polish poem, whole. Both follow the rule the rest of the bot
already keeps: the repository commits identifiers, and the words arrive over
the wire when somebody asks.

!wiersz was written the other way first, and the gate caught it. A pack of
short public-domain poems was harvested, name-filtered and committed, and
check_personal_data.sh refused it: three lines carried a real group member's
given name, and two still did after a filter that had discarded 31% of the
corpus. That is structural, not a tuning problem -- Polish verse capitalises
every line, so a line-initial capital carries no signal, and that is exactly
where a name sits. The pack now holds Wolne Lektury slugs; the poem, its
title and its author are fetched at post time and appear nowhere in git.
It is also the better version: with no name filter there are no false
positives, so the pool is larger and the attribution is a full name again.

The gate then refused the art category list too, over a painter whose given
name is somebody's. That is the popes.json case exactly, so it takes the
same answer: a file-scoped allowlist entry, still refused everywhere else.

The Commons harvest is now three modules by what they are, not by where the
line count fell: commons_api is the conversation with Commons, commons_harvest
turns categories into a pool of licensed page ids, commons_cache makes an
interrupted run resumable. Along the way it gained licences in the same
request that lists a category (the second pass was 1,500 requests at 2.3s
each), maxlag instead of a guessed sleep, 5xx retries because one 504 used to
destroy a whole run, and Wikidata for works by creators of Polish
citizenship: the Polish pool grew 15,221 -> 20,092.

Batching categories through CirrusSearch looked like a further 6x and was
measured out again: 2,404 files where the authoritative enumeration returns
2,429, a different ~1% missing on every run.

The offline run is 19s where it was four minutes, almost all of it the
deafness gate waiting out three thirty-second liveness probes to prove
something provable in three; the tick is configuration now, and e2e enforces
a 40s budget on itself so that never silently comes back.

Commands

The copy that matters is not this file: !pomoc prints the same list in the group, in Polish, one line of description per command. That version is built from the command registry at run time and cannot drift, because CommandRegistry.register takes the description as a required argument and help_command.render_help prints any command its GROUPS table forgot to file anyway, under no heading.

This file is the trigger reference — every spelling that resolves, which !pomoc deliberately does not print.

Aliases live in signal_bot/aliases.json, not in source, because they are data: adding one should never mean touching Python. Two constraints on a new one. It is subtracted from the personal-data gate's word list by _repo_vocabulary(), so it must not be name-shaped; and tests/test_nearest.py fails if it lands within edit distance of a different command's trigger, because the near-miss suggestion below would then be a coin toss. !poems is the one trigger in the table that is only just legal: it sits two edits from !pies, and passes solely because !poem is one edit away and wins the tie. Deleting !poem would fail the suite at !poems, nowhere near where the change was made.

A word nothing claims

An unrecognised !word used to be dropped in silence, which made a typo indistinguishable from the bot being down. Now it is answered, and kept:

  • within one edit (two, from six characters up) of a real trigger, the bot asks whether that is what you meant — !cta → chodziło o !kot? The distance is optimal string alignment rather than difflib's ratio, because a transposition costs one edit there and shreds the matching blocks a ratio counts.
  • otherwise it points at !zaproponuj, which files the idea.
  • either way the word and the message go into unknown_commands, which the management page shows. That is the list of commands worth writing next.

Three things stay silent, and each for its own reason. !kot ładny is a real trigger with words after it, and always has been silent. !! and !? are punctuation, not a mistyped command. And a command scoped to some other group — the album's, whose triggers are real people's names — is neither answered nor recorded, because a refusal would announce that the album exists.

add_photo and random exist only in the photo album's own groups, and only on an installation that has an album at all — everywhere else they are not commands, not refused and never logged. Both take arguments, and those arguments are resolved to pseudonym keys by the registry before any handler, log line or command_uses row sees them. See DOCS-photo-pack.md and DOCS-add-photo.md.

Why !pomoc shows the first alias and not a trigger

Command.triggers is a frozenset of folded skeletons — folding.py runs NFKC, strips diacritics and maps Cyrillic/Greek/small-caps/leet lookalikes onto ASCII, so that !gecko typed on a Russian keyboard still resolves. Everything that makes those triggers robust also makes them unprintable: the set has no order, !papież survives only as !papiez, and the styled variants come out as zalgo.

So Command.primary holds the first raw trigger instead, which aliases.json lists as the canonical Polish spelling for every command.

Two consequences worth remembering, both from folding.py:

  • A command name can never contain a digit — fold maps 0134578 onto letters, so !7dni would resolve as !tdni.
  • The styled Unicode aliases in the table above are redundant now; folding covers them. They are kept because removing an alias can only take something away.
