Design 47's catch-up of merges nobody heard is decided by ADR 0457 and bounded by ADR 0463, so other sessions read them from its frontmatter. Playbook 07 gains four lessons from 2026-10-20: a Retry is never asked beside an Approve (issue 1408), an ask is named only after it is read on the router, a check's wait is read from its delivery and not the build queue, and a catalogue change removing a module is tried against the controller (issue 1406).
