Browser sessions lapse when idle.
- Migration 0062:
web_sessions.absolute_expires_atandlast_used_at. Existing sessions keep their current expiry as the absolute cap and get at most 12 hours from the migration. expires_atslides to 12 hours after the last request (store.WebSessionIdle), never past the 7-day absolute cap; the renewal is written at most once a minute. An idle session is refused on read, and the retention sweep removes it as before.web sessions listshows last use (USED column,--jsonfield).- Users and Architecture pages; #276 leaves Known-Gaps; CHANGELOG.
Stacked on !486 (key-expiry).
Closes #276
