Ticket changes land only in the gitignored .pql/pql.db; the post-checkout/post-merge hooks rebuild it from the committed changelog on every branch switch, so un-exported tickets vanish silently (this is how the T-208-T-225 tree was lost). Add an export-and-commit step to Step 3a and a matching anti-pattern, cross-linked to the pql skill. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
