Rewrites every visitor-facing string that used an em dash, choosing the
punctuation for what the dash was doing: a colon before a list or
explanation, a comma for an aside, a full stop between two thoughts,
parentheses for an aside mid-sentence. Covers page titles and meta
descriptions, the home and admissions guide copy, school page headings
and notes, the compare page, metric labels and tooltips.
Two rewrites also fix the sentence around them: the closure banner no
longer repeats "proposed for closure", and the cut-off caveat's list of
priorities now parses.
A lone dash marking a missing value in a table cell stays: it is a data
convention, not prose. A Jest guard walks the source with the TypeScript
parser and fails on any other em dash in a string or JSX text node.

Special schools, PRUs and alternative provision teach pupils with SEND who
sit the same KS2/KS4 assessments but very few reach the mainstream "expected
standard". Their headline attainment is therefore ~0% (or a very low
Attainment 8), and the site was comparing that to the England average and
painting it red — e.g. Greenmead School (a community special school) rendered
as "0.0% — −62 pts below England average" with three 0% red SATs bars. That
portrays a special school as catastrophically failing against a benchmark
that doesn't fit it.
Add a shared `isSpecialSchool()` helper (detects every DfE special-school
establishment type — all contain "special" — plus PRUs / alternative
provision) and drop the mainstream England comparison + "below" framing for
these schools across every surface:
- Detail (primary + secondary): a plain-English context note explaining the
school is special and why the comparison isn't shown; England-average delta
chips, "England avg" hints, the SATs national markers, the Attainment-8
"vs national" bar and the trend chart's England overlay are all suppressed.
An all-zero placeholder SATs row hides the (empty) subject bar chart and the
"why is combined lower" bridge.
- Rankings / search rows (primary + secondary): the mainstream RWM / Attainment
8 stat shows "—" with no "vs national" delta, instead of "0% · −62 vs
national".
- Compare: special schools' attainment values are dropped (no misleading dot
at 0% / no "Below England average" chip); progress banding, which IS a fair
measure for special schools, is kept.
Belt-and-braces zero-guard: a whole-row zero attainment (special or a
suppressed cohort) is also treated as not-comparable, while a legitimate
single 0 (e.g. 0% exceeding at a mainstream school) stays comparable.
Tests: new isSpecialSchool unit tests (every DfE special type matched, no
mainstream false positives); an e2e journey asserts Greenmead shows the
special-school note and no England-average comparison. tsc clean; 108/108 unit.

SF1 (expert sign-off): the secondary academics 'Grade 5+ in English &
maths' and 'EBacc entry' rows rendered as bare numbers — the one place
the 'every number anchored against the England average' promise broke.
Both now show the official England anchor (already in the payload) + an
Above/Close/Below verdict chip, matching Attainment 8 (which also gains a
chip for consistency).
Button affordance: globals.css has a duplicate .btn block whose
'border: none' overrode the base '1px solid transparent', so
.btn-secondary/.btn-active's 'border-color' had no width — every outline
button (the modal's '+ Compare', search-result '+ Compare', 'Comparing')
rendered as borderless teal text. Give the outline variants the full
'border' shorthand so the outline renders regardless of the clobbered base.

Review findings: (1) the 'no KS2 baseline (COVID)' explanation was derived
from the basket-wide max year, so a school with an unrelated data gap
borrowed it from a neighbour with 2024/25 data — now judged per school on
its own latest year. (2) The '~N disadvantaged pupils' cohort multiplied
eligible_pupils and disadvantaged_pct resolved independently across years
— now both come from the same yearly row that supplies the displayed
percentage.

S1: first-choice chip banded (More than half / About 1 in 3 / Over 1 in 4
missed out) so a 44%-offered grammar isn't understated by half.
S2: Progress 8 explains its absence for 2024/25+ cohorts (no KS2 baseline,
COVID) instead of a bare 'No data'.
S3: KS4 trend charts get their own honest gap caption (2019/20-2020/21
unpublished; later years not in our dataset yet); y-axis 'Value'→'Score';
buildCompareChart exposes englandOnlyYears.
S4: all-through schools labelled in chips, rail caption says 'N schools ·
<phase> view' for mixed baskets, whole-school roll no longer judged
against the single-phase median, community section carries an all-ages
caveat.
S6 (spec §8.5): disadvantaged attainment shows the cohort behind it
('of ~50 disadvantaged pupils').
