Sitemap regeneration failed on staging. 'richmond' in the curated locality
list collides with the GIAS town Richmond in North Yorkshire (37 schools), the
registry raised, and the admin endpoint 500d — taking down sitemap generation
for all 25,000 school pages over one bad row of curated data.
The guard now skips the colliding locality and logs an error. Skipping still
achieves what the guard was for — a locality never silently shadows a town —
without letting curated data break the site. That matters beyond this bug:
GIAS town names change with no code change here, so a raise could fire
spontaneously in production later.
Also removes four localities that were London boroughs rather than districts.
Hackney, Islington, Greenwich and Ealing are local authorities with 104, 72,
108 and 115 schools and already have authority pages; a locality defined by
two or three outcodes would have been a partial near-duplicate of one — the
thin-content failure the two-namespace design exists to avoid. A test now
guards the whole borough list.
Validated against the live corpus: 15 localities, no town collisions, no
authority duplicates, all 15 clear the threshold.

The GIAS town field puts 1,819 London schools under the single value
'London', so it cannot answer 'schools in Battersea' — a query that appears in
the baseline. No single field can: parliamentary constituency gives Battersea
but not Canary Wharf, admin_ward gives Canary Wharf but not Battersea, and
neither gives Clapham or Shoreditch. So a locality is curated, defined by the
postcode districts it covers, which needs no new ingestion.
A locality may not shadow a published town: the registry raises rather than
silently costing a page that carries real demand. One below the threshold is
logged rather than raising, because a locality can legitimately be too small.
The pipeline seed mirrors the module, with a test guarding the drift — the
same arrangement gias_codes has, and for the same reason: the backend image
does not contain pipeline/.

_school_sitemap_rows tested only the latest year's row, which quietly dropped
every school with results in its history but a null row for the most recent
year — a school that stopped reporting, or whose figures were suppressed for
small-cohort disclosure.
The Mallard Academy (150367) is the case that caught it: real KS2 results for
2015-16 through 2018-19, then null rows from 2022-23 on. Its detail page shows
all four years; the sitemap omitted it. Sampling 40 of the 2,206 excluded
schools found 4 like this, so roughly 220 real pages were being withheld.
Publishable is now a property of the school, computed across every row, while
lastmod still comes from the latest row so the most recent Ofsted date wins.
The field list is a module constant shared with _has_publishable_data so the
two checks cannot drift.

Search Console reports coverage per submitted sitemap, so one file per page
family is what will make W2's location pages measurable when they land. The
index's lastmod is generation time, which is the correct semantic there —
unlike on a <url>, where it would be a claim we cannot support.
Children sit under /sitemaps/ because Next only treats a whole bracketed path
segment as dynamic; a route folder named sitemap-[...parts] would be read as a
literal static segment and never match. Confirmed by the build output, which
lists /sitemaps/[...parts] as a dynamic route.

Drops the schools with neither results nor an Ofsted grade, adds /admissions

lastmod is omitted where no date is known rather than defaulted to now. An
always-now lastmod is a claim Google learns to distrust; absent honestly
means unknown.

Earlier years are to become a paid feature, so they stop being published.
The load-bearing part is that this is a change to the API, not only to the
page. /api/schools/{urn} is public and unauthenticated: leaving
admission_distance_history in the payload while declining to render it would
have handed the whole record to anyone who opened the network tab. It is
withheld at the source, and the page follows.
Nothing changes upstream. The tap, the plausibility band and
fact_admission_distance are untouched and still load every published year, so
restoring history for entitled callers is a change to one function in
data_loader rather than a re-collection.
What the reader now gets is the latest figure on the Admissions tile, and a
Distance section that answers the question the number alone cannot: whether
their own address falls inside it. Retitled to "How far away are you?", which
is what it now does — the previous title described a record that is no longer
there.
Removed with the history: the trend chart, the year-by-year table, the
per-year verdict strip, the trend summary and the coverage note, along with
their CSS. The section goes from 743px to 417px.
One consequence worth naming. A run of years used to soften a single close
call — a home just outside one year's cut-off was usually inside another. With
one year published, the "too close to call" band is the entire safety margin
between a parent and a place they do not have, so the verdict now names its
year, and the three outcomes are tinted apart rather than distinguished by
wording alone.
The existing stylesheet test earned its keep here: the three verdict classes
were referenced before they were written, and it caught them. Unstyled, a
"beyond the cut-off" result would have been indistinguishable from an "inside"
one — the exact failure the longhand class map was written to prevent.

Completes the last-distance-offered feature against the mockup: the
year-by-year record, the same numbers drawn over real streets, and the
reader's own address measured against them.
Serving the history
The first cut deliberately served only the latest year, because a plain
series would draw a trend line straight through gaps that are absences of
publication, not of a cut-off. That reasoning is answered rather than
abandoned: cutoffYearRows classifies every year in the span, and the chart
breaks the line rather than interpolating across it.
A missing year is not one fact but three. It may be unpublished; it may be
a year the school was not oversubscribed; or there may be no record at all.
Collapsing them into "no data" throws away the reassuring case and hides
the important caveat, so each is stated in words in the table.
The claim is held to what the data supports. fact_admissions.oversubscribed
compares FIRST PREFERENCES against places, which does not establish that
every applicant was offered one — so the copy says "places available on
first preferences" and a test asserts the stronger claim never appears.
The trend summary is not a verdict
It names both endpoints and their years and lets the reader conclude. It is
withheld below four published points, and a swing under a tenth of the
earlier figure is reported as "broadly the same" rather than dressed up as
a direction.
The postcode check
This is the only place on the site that answers a question about a family
rather than a school, so most of the care went into what it refuses to say.
postcodes.io returns a centroid covering roughly fifteen addresses, which
against a 500 m cut-off is a fifth of the whole distance — so a margin
inside 100 m returns "too close to call" rather than a place a family does
not have. Unpublished years count as unknown, never as a pass. The limits
are stated before the check is used, not revealed with the answer.
The postcode is geocoded in the browser and never stored.
Both templates
Banded and selective secondaries are exactly where this matters most, so
the detail is shared. The primary page gives it a third tab; the secondary
page is one flat panel by design and renders it inline.
Absence is explained rather than reported. A selective school's missing
figure is explained by how it admits; a consistently undersubscribed school
reads as good news.
Also makes the batch loader's test double honour ORDER BY. It was a no-op,
so "latest row per URN" was really "first row in the fixture" and the test
would have passed with the sort reversed or removed.
Verified: 214 frontend tests, 54 backend, 45/53 e2e green against staging
(the 8 cut-off journeys skip until the DAG runs). Rendered offline against
the real compiled CSS in both themes and at 390px; every new surface clears
WCAG AA, measured on composited pixels.

Adds the cut-off distance a parent actually asks about — "how close do we
need to live?" — end to end: a Singer tap, dbt staging and mart models, an
Airflow DAG, and a tile on both detail templates. 3,597 schools across 57
local authorities carry a figure; the rest are unchanged.
There is no national source for this. Each LA publishes its own cut-offs in
its own format, and the collected CSV is transcribed from PDFs, spreadsheets
and web pages — so most of the work here is deciding what is safe to show.
Data
* tap-uk-school-distance loads the CSV verbatim into raw. Keyed on
(urn, year, school_name), because school_name carries the admission
route: (urn, year) alone collides on 118 keys and a reload would have
silently dropped every band but one.
* stg_school_distance applies a 25 m – 25 km plausibility band. The source
contains 0.0-mile rows (published where a school filled on a higher
criterion), 1-metre cut-offs, and one reading 533 miles — ~4% of rows,
all of which would put a visibly wrong number on a live page.
* fact_admission_distance collapses routes to one row per school per year
using the furthest, and keeps route_count so the page can say the figure
is the widest of several bands rather than the one for a given child.
Serving
* Kept out of fact_admissions: that mart is EES-derived and near-complete
for England, this one covers 57 LAs, and the two refresh independently.
* Latest year only. Coverage is ragged — a school may have 2021 and 2026
and nothing between — so a history array would invite a trend line drawn
through gaps that are absences of publication, not of a cut-off.
* The Admissions section now renders on either source. 3% of the schools
that render have a cut-off and no EES admissions row, and gating on
admissions alone would have hidden the figure on those pages.
Interface
* The year travels with the figure everywhere it appears; a cut-off
detached from its admissions round is not a fact about anything.
* "Not a fixed catchment — it moves every year" sits under every instance,
because that is the inference a parent will otherwise draw.
* Replaces a hardcoded "Historical distance cut-off data is not available
for this school" that appeared on every secondary page, including the
ones whose council does publish it. The absence is now stated only when
it is real, and names the authority that would hold it.
The tint costs the muted tokens their AA margin: measured on the composited
backdrop (not the computed one, which reports the untinted card), --text-muted
falls to 4.09:1 in dark theme. The tile uses --text-secondary instead — 6.50:1
dark, 6.60:1 light.
The DAG is manual, like the other annual ones: councils publish on allocation
day, each on its own timetable, so there is no date worth scheduling against.

The graceful-degradation fallback keys off the column named in a Postgres
UndefinedColumn error, but the matcher only stripped an `s.` alias. The two
new dim_location columns (county, parliamentary_constituency) are selected
via the `l.` alias and Postgres reports them unquoted as
"column l.county does not exist" — which the old regex failed to match at
all, returning None.
If dim_school is rebuilt (telephone/nursery present) but dim_location is not
yet (county/parliamentary_constituency missing) — plausible since they are
independently-rebuilt dbt models — the fallback branch never matched and
load_school_data_as_dataframe() returned an empty DataFrame, showing zero
schools sitewide instead of degrading those columns to NULL.
Generalise the alias prefix to `\w+\.` and cover the l.-qualified case in
tests.

Add seven school-identity fields to the detail header (both primary and
secondary views): age range, religious character, nursery and sixth-form
indicators as chips; telephone (tel: link), county and parliamentary
constituency as header details. religious_denomination, age_range and
has_sixth_form were already served; telephone, nursery_provision, county
and parliamentary_constituency are newly wired through the marts query
(with a NULL fallback for un-rebuilt marts, mirroring has_sixth_form) and
the school_info API response.
Remove three UI sections the backend never populated (always null): Year 1
Phonics, the SEN "types of additional needs" breakdown, and the average
class-size card — along with their now-dead props, route plumbing, and the
SenDetail/Phonics types + class_size_avg field.
Extend the e2e detail journey to assert the Phonics section is gone and the
new header fields render when the record carries them.

The KS2 SATs chart drew a single national-average line spanning the
full height of each subject's chart area, positioned at the national
*expected* value. But the area stacks two bars — Expected and Exceeding
— and the higher-standard/greater-depth national is a very different,
much lower figure (e.g. reading higher standard ~29% vs expected ~75%).
So the line crossed the Exceeding bar at the wrong place, making every
school's exceeding result look far below national when it wasn't.
The per-subject higher-standard nationals were already computed in the
fact_ks2_national_averages mart; they just weren't serialized. Fix:
- backend: add reading_high_pct, writing_gd_pct (writing = greater
depth) and maths_high_pct to the national-averages payload.
- SchoolDetailView: pass a nationalExceedingPct per subject, mapping
writing to the greater-depth figure.
- SatsChart: replace the single full-height line with a national marker
on each bar's own track (coral tick + "nat X%" in the bar header), so
Expected and Exceeding each sit against the correct benchmark.
KS2 only; the secondary Attainment 8 chart already uses one line for
one measure and is untouched.
Verified: tsc --noEmit, next build, and backend pytest (national
averages marts, incl. a new test guarding the per-subject nationals).

The search-result cards and map pins keyed report-card detection off
ofsted_framework === 'ReportCard', but the API sets ofsted_framework to the
raw event grouping ('Schools - S5'); worse, ofsted_grade (the carried-forward
legacy grade) was checked first and won. So report-card schools were badged
by their old grade — Barclay's pin/card read 'Outstanding · 2021' instead of
'Report Card · 2026'. Same root cause as the detail-page fix, different
surface.
Expose ofsted_rc_date on the list serialization (the report-card inspection
date, non-null only for report cards) and make both badge builders treat a
present rc-date as winning over any grade, using its year. Removes the dead
framework === 'ReportCard' branches.

Schools without KS2/KS4 results (special post-16 institutions, sixth-form

Ungraded (Section 8) inspections don't assign a fresh grade — the export

Backend now returns the full admissions_history (oldest first) alongside the

toggle ("This year | N-year trend") that swaps the Q&A for an SVG sparkline
