 - P37: seven onboarding components take their handlers in `new`, OnboardingWizard's `on_step` and `on_finish` among them; a help article no longer listed opens none; a wizard step past its last says so; a support topic no longer offered counts as none and holds Send. Kept: tasks, steps, releases and topics present, sentiments by construction, Send behind a pick. Review: 2 rounds.
 - P38: Resizable, Rotatable, RovingFocus and SelectionArea take their handlers in `new`; a resize or band whose press state is gone moves nothing; Resizable keeps the owner's raw size as its seed and fits what it draws and reports to this frame's limits; ScrollSync's leader that left syncs nothing. Kept: finite angles, items and panes present. Review: 2 rounds.
 - P39: no change. Kept: palette and syntax tokens named from constant tables, chart hues checked against the fixed eight (the owner's contract). Review: 1 round.
+- P40: no change. Kept, as AGENTS.md says: catalogs checked against each other at construction, message keys and arguments from code, Ely's locale table, the owner's switch over its own catalogs, constant date patterns. Review: 1 round.
