//! Optional schema-11 query caches, maintained within transactions.

// Invalidation removes cached identities too: retention and older writers

// must not leave session identifiers in an unusable cache.

// Include every table and retain bounded SQLite analysis so

// combined filters can choose the more selective expression index.

// Optional caching must not reject valid events from separate groups

// when only the combined metric exceeds i64.

// Outside this window, long retained histories use the original query.

// Today, days before the first observation and calendar gaps need no

// stored zero rows. Check absent partitions against daily_usage and usage_events

// so an older event-only writer cannot make a stale cache appear valid.
