ADR 0022 records the channel: its scope, the writes that notify and when,
the 150 ms wait on the subscriber side, stale answers ignored, and who may
subscribe. architecture.md gets its row in the ADR table, plus the rows this
change made wrong (onboardingService, useOnboardingChecklist, the new
dataEvents service, the contexts folder). The changelogs record rule D9: a
profile that already had transactions hides the getting-started checklist
the first time it is opened with this version.
