It was still browsing the flat category list and the free-text keyword
tags, neither of which is how questions are arranged any more. A
discipline holding six hundred questions three levels down showed as
"(0)" because only what was filed directly on the node was counted.
/topics now walks the tree — discipline, sub-topic, condition — with
each node counted over its whole subtree, and any node can be quizzed
whole. /objective scopes every quiz to one exam, listing only objectives
that actually have questions. The keyword browse is gone with the tags.
Chat is where you answer, not where you read the teaching: explanations
are abridged to about a screenful, cut at a sentence, with markdown and
cross-reference markers stripped and a link to the site when there is
more. Per-option reasoning and figures are not sent — the bot never did,
and now says where they are.
Still read-only, and now says so: no account, no history, and a quiz
that lives only until it ends or /stop. `is_shared` remains the only
gate between an anonymous stranger and the bank, applied in one place.
