- Add backend/src/lib/cache.js — in-process TTL Map cache with
prefix-based invalidation; no external dependencies
- Cache /experiments/:id/calendar?field=X per (experimentId, field).
Invalidated immediately on any DailyStatus write.
- Cache /experiments/:id/daily-statuses per (experimentId, date, analysisOnly).
Invalidated immediately on any DailyStatus write (create/update/delete
and analysis-summary saves all clear the relevant prefix).
- Add ?analysisOnly=true to /daily-statuses: filters rows where
analysis_summary IS NOT NULL. Charts are the only consumer and already
discard rows without analysis data; pre-filtering server-side avoids
sending the full status payload (71 rows → 1 for this experiment).
- ExperimentCalendar: remove allStatuses prop, fetch calendar data
directly via API. The component now issues one small GET per field
selection change instead of the parent loading thousands of rows upfront.
- ExperimentDetail: pass analysisOnly:true to getDailyStatuses;
drop allStatuses prop from ExperimentCalendar. Cold experiment page
load no longer fetches every daily status record.
