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.
