The "Peaked at X%" hint didn't say which metric it referenced, leaving
parents to guess. Both branches now lead with "Reading, Writing & Maths".

Add lib/analytics.ts with a single typed track() wrapper. SSR-safe,
never throws, no-ops when Umami isn't loaded. Event names form a
fixed union so refactors stay safe.
14 events wired:
Discovery (3)
search_submitted FilterBar submit + near_me path
near_me_used all geolocation outcomes
empty_results search returns 0 schools
Engagement (5)
school_viewed SchoolDetail + Secondary on mount, with
urn / phase / local_authority / from
section_nav_used section-nav links on both detail views
chart_metric_changed mobile chart chip switch
metric_compared_in_rankings rankings metric dropdown
external_link_clicked Ofsted / school website / DfE (declarative
data-umami-event attributes)
Conversion (5)
compare_school_added search/rankings/detail/compare sources
compare_school_removed detail toggle and compare page
compare_viewed once per session when there's a selection
(school_count, phase_mix)
compare_metric_changed compare page metric dropdown
compare_shared native sheet vs clipboard distinguished
Operational (1)
api_error caught in handleResponse, includes
endpoint / status / route
Suggested Goals to configure in the Umami dashboard for the funnel
report: search_submitted → school_viewed → compare_school_added →
compare_viewed → compare_shared.

The Results Over Time chart on the school detail page was overcrowded
on phones — 5-item legend wrapping over the plot area, a hidden right
y-axis still rendered for the (collapsed) progress series, fixed
0–100 percentage scale that flattened all variation, angled x-axis
labels eating vertical space.
At ≤640px the chart now renders one metric at a time, selected via a
chip strip above the plot. No more legend. No more dual y-axis. The
y-axis auto-tightens around the actual data range so variation is
visible (a school sitting in the 70–90% band now uses a 65–95 axis
instead of squashing onto a 0–100 line). A small subtitle above the
chips sets the subject context ("KS2 SATs · Reading, Writing & Maths"
or "GCSE results · Year 11") so chip labels can describe the *view*
rather than re-stating the subject.
Chip labels are spelled out in parent-facing language — no internal
shorthand like "RWM":
Primary (KS2): At expected level (default)
Above expected level
Pupil progress (shows 3 series + mini-legend)
Secondary (KS4): Attainment 8 (default)
English & Maths grade 4+
Progress 8
Chips disable themselves (greyed, with a "No data for this school"
title) when the underlying series has no data points. Desktop
behaviour is unchanged — the full multi-series chart with dual y-axis
still renders >640px.

P1 (backend/data_loader.py): Add load_latest_school_data() which pre-computes
the one-row-per-school latest-year snapshot (groupby, prev-year trend merge)
once at startup instead of on every /api/schools request. get_schools route
now starts from the cached snapshot rather than rebuilding it.
S3 (backend/app.py): Wrap synchronous geocode_single_postcode() call in
asyncio.to_thread() so postcode lookups no longer block the uvicorn event
loop. Admin reload endpoint also uses to_thread for both cache primes.
P2 (nextjs-app/components/HomeView.tsx): Add mapParamsRef guard so switching
back to map view does not re-fetch 500 schools when search params haven't
changed. Reset ref on new searches so fresh data is always fetched.
P3 (nextjs-app/lib/chartSetup.ts): Extract Chart.js registration into a
shared side-effect module. ComparisonChart and PerformanceChart now import
it instead of each calling ChartJS.register() independently.
P4 (backend/database.py): Remove unnecessary db.commit() from the read-only
get_db_session() context manager — saves a DB round-trip on every request.
P5 (backend/database.py): Add pool_recycle=1800 to SQLAlchemy engine to
prevent stale TCP connections from accumulating in long-running processes.

Previously the dashed reference line was a flat horizontal at the latest
year's national average across all historical data, implying the national
figure was constant. Now the backend returns per-year averages in `by_year`
and the chart maps each data year to its own national average, so the
reference line correctly reflects how the national picture changed over time
(including COVID recovery dip/recovery).
- backend: /api/national-averages now includes `by_year` list alongside
existing `year`/`primary`/`secondary` latest-year snapshot
- types: NationalAverages extended with `by_year: NationalAveragesYear[]`
- PerformanceChart: accepts `nationalByYear` prop; builds per-year series
aligned to school data years, falling back to scalar prop if absent
- SchoolDetailView + SecondarySchoolDetailView: pass `nationalAvg.by_year`

History chart
- Strip the redundant school-name title (already the page heading)
- Default to 2 visible lines: Reading, Writing & Maths expected % (teal,
bold) + Exceeding (gold, lighter); progress score lines hidden by
default, togglable via legend
- Add dashed national average reference line for RWM (primary) or
Attainment 8 (secondary) so the school's trajectory is always in
context
- Add trend summary chip above the chart computed from the data
("↓ Peaked at 90% (2016/17), currently 70%")
- Add COVID footnote when 2019/20 and 2020/21 data is absent
Ofsted section
- Collapse the four identical "Outstanding / Outstanding / Outstanding /
Outstanding" boxes into a single prose line when all sub-grades match
the overall verdict; show individual cards only when grades differ
SATs sub-metrics
- DeltaChip vs national average on Expected level row for Reading,
Writing and Maths (national averages already in the API response)
Admissions
- Fix label: "Year 3 places per year" → "Reception places per year" for
primary schools
Pupils & Inclusion
- DeltaChip + national avg hint on Eligible for pupil premium and
Pupils receiving SEN support (both keys present in /api/national-averages)

Apply formatAcademicYear to all year displays in ComparisonChart, ComparisonView,
PerformanceChart, and RankingsView. Remove old vanilla JS frontend and CSV data
directory — both superseded by the Next.js app and Meltano pipeline.

- Backend: replace INNER JOIN ks2 with UNION ALL (ks2 + ks4) so primary
and secondary schools both appear in the main DataFrame
- Backend: add /api/national-averages endpoint computing means from live
data, replacing the hardcoded NATIONAL_AVG constant on the frontend
- Backend: add phase filter param to /api/schools; return phases from
/api/filters; fix hardcoded "phase": "Primary" in school detail endpoint
- Backend: add KS4 metric definitions (Attainment 8, Progress 8, EBacc,
English & Maths pass rates) to METRIC_DEFINITIONS and RANKING_COLUMNS
- Frontend: SchoolDetailView is now phase-aware — secondary schools show
a GCSE Results section (Att8, P8, E&M, EBacc) instead of SATs; phonics
tab hidden for secondary; admissions says Year 7 instead of Year 3;
history table shows KS4 columns; chart datasets switch for secondary
- Frontend: new MetricTooltip component (CSS-only ⓘ icon) backed by
METRIC_EXPLANATIONS — added to RWM, GPS, SEN, EAL, IDACI, progress
scores and all KS4 metrics throughout SchoolDetailView and SchoolCard
- Frontend: METRIC_EXPLANATIONS extended with KS4 terms (Attainment 8,
Progress 8, EBacc) and previously missing terms (SEN, EHCP, EAL, IDACI)
- Frontend: SchoolCard expands "RWM" to "Reading, Writing & Maths" and
shows Attainment 8 / English & Maths Grade 4+ for secondary schools
- Frontend: FilterBar adds Phase dropdown (Primary / Secondary / All-through)
- Frontend: HomeView hero copy updated; compact list shows phase-aware metric
- Global metadata updated to remove "primary only" framing
