Per-status texts check AI consent before the unchanged-data refresh can
re-stamp them, the comprehensive fingerprint folds in the comparison
baseline and generation language so toggling either regenerates once,
and profile, threshold and source-priority writes evict the analytics,
targets and derived caches they feed. CSV export neutralises spreadsheet
formula prefixes on free-text cells while numeric columns stay typed,
the derived batch validates its type token against the measurement enum
and carries a per-user rate limit, and a dose synced from the phone app
counts as the interactive write it is. Background cache refresh
failures log a structured event instead of vanishing, the warm queue
runs visit-triggered jobs alongside the nightly walk, the formatter
memo evicts one entry instead of flushing wholesale with its option
objects frozen, the targets cold build bounds its fan-out, and time in
bed unions every writer's envelope while stages stay with the richest
recorder.
Intl.DateTimeFormat instances are memoised per locale, timezone and
options signature — construction dominated the 365-day ledger build and
the hot path drops about fivefold. A batched GET /api/medications/compliance
serves every card from one request through the same per-medication cache
cells the detail page reads, replacing the per-card fan-out; the list
response stays untouched so the due line never waits on a ledger build.
The medications and compliance buckets serve stale-while-revalidate,
interactive writes evict while background bulk sync marks stale, the
per-id route defers ownership and schedule reads until a cache miss,
and the card body reserves constant slots for the status and cycle
lines so late data stops shifting the layout.
