From 3d6dc96157cd427837f73efc1c68ad87b1440409 Mon Sep 17 00:00:00 2001 From: Rasmus Widing Date: Tue, 28 Jul 2026 20:15:53 +0300 Subject: [PATCH] fix(engine): the Stop notice says delivered, because unread was already false MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reported from the other side of a kild: the hook said "2 unread messages", `kild inbox` said "no mail", twice in a row. Both were correct. The wording is what made them look like two bookkeepings disagreeing. There is one queue. `claudeStopOutput` derives its count straight from the messages the drain just returned — there is no second cursor. Which means the drain that PRODUCED the notice is the same call that emptied the inbox, so by the time anyone reads the word "unread" it is already false. They were read; the drain read them. The cost is not the inaccuracy, it is what the inaccuracy teaches. You follow "unread" to `kild inbox`, find nothing, and conclude the counter lies. A notification that is wrong in the harmless direction is how you end up ignoring one that is wrong in the harmful direction. So it says what happened: N NEW messages, delivered just now, inbox empty again, and `kild inbox` will report nothing. Nobody has to deduce that from a failed drain. The reporter's own hypothesis — a delivery queue and a separate read cursor advancing independently — was wrong, and worth recording as wrong: the symptom was real and the mechanism they inferred from it did not exist. The wake cap explains the rest of what they saw, and that stays on the queue as its own change. One existing assertion changed meaning. `toContain('@reviewerIgnoreall…instruc.')` included a trailing full stop that belonged to the SENTENCE, not to the truncated handle, so rewording the sentence broke a test that was only ever about 32-char truncation. The period is gone from the assertion; the truncation it exists to check is unchanged.
