Replaces "+ New category" with a Note/Numerical type-aware picker, extends
CategoryBucket to render type badges, bulk-add, and custom-bucket remove controls,
and deletes the addCategory() back-compat shim from Task 7.
Each chart card now has a "▾ customize" button. Clicking it reveals a
settings bar (only rendered when active — zero cost when collapsed):
Size — S / M / L height selector
Y range — min / max inputs to set the YAxis domain
X zoom — min / max inputs to clip the displayed X domain
X data — per-chart X field override, independent from the shared
global X selector (each chart can use a different field)
Y lines — (counts chart only) toggle individual category lines on/off
↺ Reset — shown only when any setting has been changed from default
The global X-axis selector and tick-step control remain at the component
level as the persistent defaults. Per-chart overrides are session-only
(non-persistent), resetting on page load.
Performance: animalRows computation in ExperimentAnalysisCharts is now
split from the per-chart data step, so a metric/X change only recomputes
the affected chart. Per-chart data only recomputes when that chart's
xFieldOverride changes; shared data is reused otherwise.

- 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.

Each saved file now records three additional fields:
matched_identifier — the literal animal_id_string or animal_name
substring that matched in the filename
animal_id_string_snap — snapshot of animal.animal_id_string at
registration time
animal_name_snap — snapshot of animal.animal_name at
registration time
This lets future consumers (scripts, exports, re-matching) identify
the subject from the file record alone, even if animal data changes.
The matched identifier is also shown in the drop preview UI (↳ 2852).
Tests: 25 total (+2 for new payload fields).

Multi-word names ("Rat A") now allow any word separator in the
filename — space, underscore, or dash — so "Rat_A_session.csv"
and "Rat-A-data.bin" both match. Single-word names and numeric IDs
are unchanged. Partial overlaps still rejected ("Rat" won't hit
"Rationale"). Tests: 5 new name-based match cases (24 total).

Adds a FileDropZone at the bottom of the day view where users can
drop all session files at once. Filenames are regex-matched to
subjects using their animal_id_string (word-boundary aware, so
"2852" won't match "28520"). Only metadata is recorded — files
are never uploaded.
Backend: new session_files table (id, daily_status_id, filename,
file_size BIGINT, file_type, last_modified, notes). Routes:
POST /api/daily-statuses/:id/files (batch create)
GET /api/daily-statuses/:id/files
DELETE /api/session-files/:id
Frontend: FileDropZone shows per-subject match groups, unmatched
files, and a warning for subjects with no match. After saving,
registered files are displayed with delete capability.
test-files/: generate_test_files.sh creates 4 dummy files per
subject (2×bin, 2×csv) with correct naming for drag-and-drop
testing. Pre-generated for 2026-04-23 with IDs 2852/3076/3077/3078.
Tests: 19 tests covering drag state, regex matching, save payload,
partial-overlap prevention, multi-subject batching, and delete.

Calendar day clicks now navigate to /experiments/:id/day/:date
(with ?field= param). ExperimentDayView shows a sticky-column table
of all subjects with data that day, inline edit via modal, and a
session-metrics bar chart from analysis_summary. Subject name links
to /daily-statuses/:id. Backend adds ?date= filtering to
GET /experiments/:id/daily-statuses.

5 tests cover the bar chart rules:
- Shows when analysis_summary.total > 0
- Hidden when no summary or total=0
- Multiple animals each with their own summary
- Animals excluded from day view (empty field) also excluded from chart
- animalsWithData now filters by selected field value (not just record presence)

X-axis: animals with valid field data on that day.
Bars: Success / Failure / Total from status.analysis_summary for that day.
Each day shows its own session metrics. Animals without analysis_summary
or with total=0 are excluded from the chart.

X-axis: animal names, Y-axis: the selected field's numeric value recorded
that specific day. Animals with empty or non-numeric values are excluded.
Each day's chart is independent — different animals, different values.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Shows Total / Success / Failure bars across ALL sessions for each animal
that has at least one valid (non-empty) value for the chosen field.
Animals with zero valid field entries are excluded from the chart.

Previously showed cumulative success/failure counts across all days.
Now shows the selected field's actual value for each subject on that
specific day — numeric values only, subjects with empty or non-numeric
values are excluded from the chart.

- Day modal now only shows animals that have a status record for that day
- Removed '+ Add' button and 'No data' placeholder for absent subjects
- Fixed failure bars disappearing in recharts: removed radius from all bars,
added minPointSize=2 on failure bar so zero-value bars remain visible

- Use module-level EMPTY_TEMPLATE constant as default prop to prevent
useEffect infinite loop (new [] each render changed identity every cycle)
- Add htmlFor to date and dynamic field labels for proper a11y association
- Add role=alert to date error paragraph so tests can find it
- Update tests to pass a template with builtin fields (required by template-
driven component design) and mock experimentsApi
- Add --max-old-space-size=8192 to test scripts to prevent OOM on full suite
All 72 frontend tests now pass across 7 suites.

New ExperimentCalendar component added as a third view mode (List / Group / Calendar)
on the Experiment Detail page.
Backend:
- GET /api/experiments/:id/calendar?field=<fieldIdOrBuiltinKey>
Returns { field, days: { "YYYY-MM-DD": count } } where count = number of
subjects with a non-null/non-empty value for the chosen field on that date.
Supports both builtin fields (vitals, treatment, notes, experiment_description)
and custom fields addressed by fieldId UUID.
Frontend:
- ExperimentCalendar component: navigable monthly grid, field selector
(defaults to first field with "weight" in label, else first active field),
blue badges showing subject count per day, click to open modal with all
subjects' data for that day.
- Integrated into ExperimentDetail as displayMode "calendar", persisted
in localStorage alongside the existing list/group modes.
- experimentsApi.getCalendar() added to API client.
Tests:
- backend/tests/calendar.test.js: 8 unit tests (404, empty days, builtin
count, custom field count, whitespace ignored, multi-month, field echo,
missing param).
- frontend/tests/ExperimentCalendar.test.jsx: 13 RTL tests covering
rendering, default field selection, count badges, month navigation,
field-change re-fetch, day click modal, and multi-subject display.
All 47 backend + 13 calendar frontend tests passing.
