# Compare Screen Frontend Rebuild Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Rebuild `/compare` in the Next.js app to match the approved mockups — parent-first sections (At a glance / Ofsted / Academics / Getting a place / Who goes there / Explore trends), England-average anchoring with provenance-correct labels, mobile-first measure-first layout — consuming the enriched `/api/compare` payload from PR #34, with e2e journeys updated in the same PR (they are the promotion gate).
**Architecture:** `ComparisonView` becomes an assembly of section components fed by one enriched fetch. All comprehension rules from the two expert reviews live in a pure, jest-tested module (`lib/compareLogic.ts`) — components stay presentational. The mockups are committed at `docs/superpowers/specs/mockups/compare-desktop.html` and `compare-mobile.html`: **all user-facing copy (labels, tooltips, chips, footnote wording) is taken verbatim from them** — they carry two rounds of education-expert review; do not paraphrase.
**Tech Stack:** Next.js (app router, SSR page + client view), CSS modules, Chart.js (existing `ComparisonChart`), Jest (`npm test` in `nextjs-app/`), Playwright e2e (`e2e/`).
## Global Constraints
- **Never push to `main`.** Branch: `feat/compare-frontend-rebuild`.
- **Copy is expert-reviewed:** take it verbatim from the committed mockups. Binding rules (spec §8): Ofsted scale labels come from the API's `report_card[..].label` (never hardcode area labels beyond the mockups'); official DfE numbers say "England average", computed ones say "state-school average (computed from our dataset)"; the 2021/22 chart gap note says "DfE didn't publish school-level figures for 2021/22"; never derive an overall grade from report-card areas; safeguarding never counts as a graded area; "Latest Ofsted inspection", "EHC plans", "at or above capacity", "Over 1 in 4", "first choice (officially 'first preference')".
- **Mobile-first:** the measure-first stacked layout (mobile mockup) is the base CSS; the desktop label-column grid is the `min-width` enhancement.
- **URL contract unchanged:** `?urns=` (and `metric=` now scoped to Explore trends) keep working; share flow, `useComparison` basket, phase tabs, and `compare_viewed`/`compare_metric_changed` analytics events are preserved.
- **Do not run a local server** (CLAUDE.md); verification = jest + `tsc` + the e2e suite against staging after merge. e2e must pass on **staging data** — remember staging has partial history: assert against the *latest* year, never oldest.
- Existing `/api/compare` consumers elsewhere in the app (SchoolDetail links, toasts) must not break — the response is additive, and this PR only rewrites the compare page's own components.
- **Post-v1 (do not build):** IDACI, attendance section, gender-split/absence tier-2 measures, finance (spec §4).
---
### Task 0: Branch + design sources
- [ ] `git checkout main && git pull && git checkout -b feat/compare-frontend-rebuild`
- [ ] The mockups and this plan are already in the working tree (`docs/superpowers/specs/mockups/compare-{desktop,mobile}.html`) — commit them: `docs: compare mockups as frontend design source + rebuild plan`
---
### Task 1: Types for the enriched payload
**Files:**
- Modify: `nextjs-app/lib/types.ts` (extend `SchoolResult`, `ComparisonData`, `ComparisonResponse` — located around lines 293-314)
**Interfaces (produced for every later task):**
```ts
export interface ReportCardEntry { code: number; label: string; }
export interface OfstedBlock {
framework: string | null;
inspection_date: string | null;
inspection_type: string | null;
overall_effectiveness: number | null;
grade_source: 'graded' | 'ungraded_carried_forward' | null;
quality_of_education: number | null;
behaviour_attitudes: number | null;
personal_development: number | null;
leadership_management: number | null;
early_years_provision: number | null;
sixth_form_provision: number | null;
rc_safeguarding_met: boolean | null;
report_card: Record<string, ReportCardEntry>;
ofsted_page_url: string;
report_url: string | null;
}
export interface CensusBlock {
year: number | null; total_pupils: number | null;
female_pupils: number | null; male_pupils: number | null;
fsm_pct: number | null; eal_pct: number | null;
}
export interface AdmissionsRow {
year: number; school_phase: string | null;
places_offered: number | null; total_applications: number | null;
first_preference_applications: number | null; first_preference_offers: number | null;
first_preference_offer_pct: number | null; oversubscription_ratio: number | null;
oversubscribed: boolean | null;
total_offers: number | null; second_preference_offers: number | null;
third_preference_offers: number | null;
cross_la_applications: number | null; cross_la_offers: number | null;
}
export interface DeprivationBlock {
lsoa_code: string | null; idaci_score: number | null; idaci_decile: number | null;
}
export interface BenchmarkBlock {
eal_pct: number | null; sen_support_pct: number | null;
disadvantaged_pct: number | null; median_pupils: number | null;
disadvantaged_rwm_expected_pct?: number | null;
}
export interface Benchmarks {
source: string; year: number;
primary: BenchmarkBlock; secondary: BenchmarkBlock;
}
export interface NationalAverages {
year: number;
primary: Record<string, number>;
secondary: Record<string, number>;
by_year: Array<{ year: number; primary: Record<string, number>; secondary: Record<string, number> }>;
}
```
- [ ] **Step 1:** Add the interfaces above; extend `ComparisonData` with optional `ofsted?: OfstedBlock | null; census?: CensusBlock | null; admissions?: AdmissionsRow | null; admissions_history?: AdmissionsRow[]; deprivation?: DeprivationBlock | null;` and `ComparisonResponse` with `national_averages?: NationalAverages; benchmarks?: Benchmarks;` (optional so the UI degrades on an old backend). Extend `SchoolResult` with the ten new yearly columns (`reading_progress_lower_ci``maths_progress_upper_ci`, `writing_working_towards_pct`, `progress_8_banding: string | null`, `attainment_8_disadvantage_gap`, `progress_8_disadvantage_gap`).
- [ ] **Step 2:** `cd nextjs-app && npx tsc --noEmit` → clean. Commit: `feat(compare): types for enriched comparison payload`
---
### Task 2: `lib/compareLogic.ts` — the comprehension rules, jest-tested
**Files:**
- Create: `nextjs-app/lib/compareLogic.ts`
- Test: `nextjs-app/__tests__/lib/compareLogic.test.ts`
**Interfaces (produced):**
```ts
export type Verdict = 'above' | 'close' | 'below';
export function verdict(value: number, anchor: number, tolerance?: number): Verdict; // default tolerance 2pp
// Report-card summary per spec §4.2: count graded areas per label (best
// first), NAME any 'Needs attention'/'Urgent improvement' area, safeguarding
// separate, "No areas need attention" reassurance when applicable.
export interface ReportCardSummary {
counts: Array<{ label: string; count: number }>; // best grade first
problems: Array<{ areaLabel: string; label: string }>; // named, never counted-away
safeguarding: 'met' | 'not_met' | null;
allClear: boolean;
}
export function summariseReportCard(ofsted: OfstedBlock): ReportCardSummary;
// One display model for all three inspection regimes.
export type OfstedDisplay =
| { kind: 'none' }
| { kind: 'graded'; grade: number; gradeLabel: string; carriedForward: false }
| { kind: 'carried_forward'; grade: number; gradeLabel: string; carriedForward: true }
| { kind: 'report_card'; summary: ReportCardSummary };
export function ofstedDisplay(ofsted: OfstedBlock | null | undefined): OfstedDisplay;
export const OFSTED_LEGACY_GRADES: Record<number, string>; // 1 Outstanding, 2 Good, 3 Requires improvement, 4 Inadequate
// Human-readable area label from an rc_ key: 'rc_attendance_behaviour' →
// 'Attendance & behaviour' (mapping table copied from the mockups' area rows).
export function rcAreaLabel(key: string): string;
// Admissions, one consistent chip metric (first-preference success).
export interface AdmissionsSummary {
firstPrefPct: number | null;
chip: { tone: 'good' | 'warn' | 'neutral'; text: string } | null; // "97% of first choices offered" / "Over 1 in 4 first choices missed out" wording per mockups
interest: string | null; // "Named on 457 forms · 180 places"
}
export function summariseAdmissions(a: AdmissionsRow | null | undefined): AdmissionsSummary;
// CI-based progress band for historical years (null when no CI published).
export function progressBand(score: number | null, lower: number | null, upper: number | null):
'above' | 'average' | 'below' | null; // CI entirely >0 → above; entirely <0 → below; straddles → average
// Dot-strip geometry (used by the DotStrip component; pure for testing).
export interface StripPoint { pos: number; labelAbove: boolean; value: number; schoolIndex: number; }
export function stripPositions(values: Array<number | null>, min: number, max: number): StripPoint[];
// pos = (v-min)/(max-min)*100 clamped 0..100; labels within 4% of range of a
// lower neighbour flip above (the mockups' collision nudge).
```
- [ ] **Step 1: Failing tests** covering, at minimum:
- `summariseReportCard`: 4 Strong + 2 Expected + 1 Needs-attention + safeguarding met → counts `[Strong standard×4, Expected standard×2]`, `problems=[{areaLabel:'Attendance & behaviour', label:'Needs attention'}]`, `allClear=false`; safeguarding NEVER in counts; all-Expected+met → `allClear=true`; labels come from the input's `.label` (assert the function never invents "Attention needed").
- `ofstedDisplay`: report_card present → `kind:'report_card'` even if a legacy grade also exists; `grade_source:'ungraded_carried_forward'``carriedForward:true`; null → `'none'`.
- `summariseAdmissions`: 73% → warn chip text `Over 1 in 4 first choices missed out`; 97% → good chip `97% of first choices offered`; 100% → `All first choices offered`; interest string `Named on 342 forms · 120 places`; nulls → null chip.
- `progressBand`: (1.2, 0.4, 2.0)→above; (-1.2, -2.0, -0.4)→below; (0.3, -0.5, 1.1)→average; missing CI → null.
- `stripPositions`: 100120 domain maps 106→30; values 91 and 92 on 0100 → second label flips above; nulls skipped.
- `verdict`: 87 vs 62 → above; 61 vs 62 → close (within 2pp); 40 vs 62 → below.
- [ ] **Step 2:** `cd nextjs-app && npm test -- compareLogic` → FAIL. **Step 3:** implement. **Step 4:** pass + `tsc` clean. **Step 5:** Commit: `feat(compare): comprehension logic (report cards, admissions, verdicts, strips)`
---
### Task 3: `DotStrip` component
**Files:**
- Create: `nextjs-app/components/DotStrip.tsx`, `nextjs-app/components/DotStrip.module.css`
**Interfaces:**
```ts
export interface DotStripProps {
label: string;
values: Array<number | null>; // one per school, school order = chart colour order
anchor?: { value: number; label: string } | null; // e.g. {62, "England 62%"} — omit when benchmark absent
min?: number; max?: number; // default 0..100
unit?: string; // default '%'
tip?: string; // title tooltip on the label
note?: string; // e.g. "(teacher-assessed)" suffix handled by caller in label
}
```
- [ ] Render per the mockups' `.strip-row` anatomy: label row, 4px track, England tick + tick label, 16px dots coloured by `CHART_COLORS[index]` with white ring, value labels below (flipped above on collision via `stripPositions`). `role="img"` + `aria-label` enumerating anchor and each school's value (copy the aria pattern from the mockups). CSS module mirrors the mockup styles using the app's CSS variables (`--border-light`, `--text-muted`, etc.).
- [ ] Jest: render with `@testing-library/react` (already configured — see `__tests__/components/SecondarySchoolRow.test.tsx` for the harness pattern): asserts aria-label content, tick present when anchor given, absent otherwise.
- [ ] Commit: `feat(compare): DotStrip with England-average anchor`
---
### Task 4: Section components — At a glance, Ofsted, Getting a place, Who goes there
**Files:**
- Create: `nextjs-app/components/compare/CompareAtAGlance.tsx` (+ `.module.css`)
- Create: `nextjs-app/components/compare/CompareOfsted.tsx`
- Create: `nextjs-app/components/compare/CompareAdmissions.tsx`
- Create: `nextjs-app/components/compare/CompareCommunity.tsx`
- Create: `nextjs-app/components/compare/compareSections.module.css` (shared measure-first grid)
- Test: `nextjs-app/__tests__/components/CompareOfsted.test.tsx`
**Shared layout contract (all four):** props `{ schools: School[]; data: Record<string, ComparisonData>; benchmarks?: Benchmarks; nationalAverages?: NationalAverages }`. Base CSS is the mobile mockup's measure-first stack (`.measure` card → `.srow` per school with colour dot + short name + value + chip + note); at `min-width: 761px` it becomes the desktop mockup's grid (200px row-label column + one column per school). Section headers use the existing `.section-title` idiom; every section carries its mockup "how" line verbatim.
**Content per section = the mockups, row for row.** Structure/tone rules already encoded in Task 2's helpers:
- *At a glance*: Latest Ofsted inspection row (badge via `ofstedDisplay`; report-card case renders `ReportCardSummary` chips — counts best-first + named problem chips + safeguarding line); expected-standard row (big % + `verdict` chip vs `national_averages.primary.rwm_expected_pct`, small "England average N%"); Getting a place row (chip from `summariseAdmissions`, note = `interest`); Size row (pupils + "at or above capacity"/"N% full" from census/capacity, vs `benchmarks.*.median_pupils` for "larger/smaller than average" phrasing).
- *Ofsted*: the section's `how` paragraph (regime explanation + non-comparability + "Expected standard" disambiguation) verbatim from the desktop mockup; Result row; Inspected row (date + "4+ years ago" chip when >4y, computed from `inspection_date`); Judgement detail row — **one chip-list grammar for both regimes** (legacy subgrades via `OFSTED_LEGACY_GRADES`; report card via `report_card` labels; "We don't hold area-by-area detail for this inspection" when neither); Ofsted page row linking `ofsted_page_url` ("<Name>'s Ofsted page →").
- *Getting a place*: `how` paragraph (first preference/equal preference/offer-day caveats) verbatim; Interest row; first-choice success row with mini bar; "What this means" row (distance note: "check the school's admission criteria (for most non-faith primaries, distance decides)" only when oversubscribed).
- *Who goes there*: pupils-on-roll (census + capacity), girls/boys, FSM (chip vs `benchmarks` with "state-school average" wording), EAL, SEN (tooltip incl. "EHC plans" + specialist-provision note), faith, ages · nursery, run by (trust name or "<LA> council").
- [ ] **Step 1:** Failing jest test for `CompareOfsted` (the riskiest): given one graded school, one carried-forward, one report-card school → asserts the three Result cells ("Outstanding" badge; badge + carried-forward marker; "Report card" + no invented overall grade), the chip-list judgement rows, and the comparability note appearing only for the mixed case.
- [ ] **Step 2-4:** Implement all four sections; test passes; `tsc` clean; `npm test` full suite green.
- [ ] **Step 5:** Commit: `feat(compare): at-a-glance, Ofsted, admissions and community sections`
---
### Task 5: `CompareAcademics` — strips + More measures
**Files:**
- Create: `nextjs-app/components/compare/CompareAcademics.tsx`
- Test: extend `nextjs-app/__tests__/lib/compareLogic.test.ts` with the metric-extraction helper below
**Interfaces:**
- Add to `compareLogic.ts`: `latestValues(data, urns, metricKey) => Array<number|null>` (latest non-null yearly value per school) — tested.
- [ ] Tier 1 strips (always visible), each a `DotStrip` with the England anchor from `national_averages.primary`: RWM expected, Reading, Writing, Maths, "Working at a higher standard than expected" (tooltip: composition sentence from the mockups). Section `how` line: "tests and teacher assessments … writing is assessed by teachers, not tested" verbatim.
- [ ] Tier 2 `<details>` "More measures — grammar, punctuation & spelling, science, average scaled scores": GPS + Science (teacher-assessed, tooltip verbatim) with anchors from `national_averages` **when present, no tick + honest note when null**; scaled scores (reading/maths/GPS) on `min=100 max=120` with the mockups' window caption.
- [ ] Equity row: disadvantaged pupils' RWM per school + chip vs `benchmarks.primary.disadvantaged_rwm_expected_pct` with the "state-school average" wording and small-cohort tooltip verbatim.
- [ ] Secondary phase variant (when active phase is secondary): tier-1 rows are Attainment 8 (anchor `national_averages.secondary.attainment_8_score`), Progress 8 banding (chip showing `progress_8_banding` verbatim — DfE's own label), grade 5+ English & maths %; tier-2: EBacc entry/APS. Measure-first rows (no strips needed for banding).
- [ ] `npm test` + `tsc`; commit: `feat(compare): academics strips with England anchors and More measures`
---
### Task 6: Trends explorer — England line, gap-honest axis, series bug
**Files:**
- Modify: `nextjs-app/components/ComparisonChart.tsx`
- Create: `nextjs-app/components/compare/TrendsExplorer.tsx`
- Test: `nextjs-app/__tests__/components/ComparisonChart.test.tsx`
- [ ] **Step 1 (bug first): root-cause the missing third series** seen on production (3 schools in table, 2 lines on chart). Write a failing jest test: 3 schools whose `yearly_data` year values are floats (`202425.0`) vs the labels array — the suspect is the year-matching in `ComparisonChart.tsx:69` (`years.map(...)` built from school 1 only + strict equality against other schools' years). Fix so every school's series renders and years are the union of all schools' years, sorted.
- [ ] **Step 2:** Add optional `nationalByYear?: Record<number, number|null>` prop → dashed grey "England average" dataset (colour `--text-muted`, `borderDash:[5,4]`, no fill, `spanGaps:false`).
- [ ] **Step 3:** Gap honesty: x-axis category labels include 2019/20 and 2020/21 as empty slots (band label "tests cancelled 2019/202020/21" via a Chart.js annotation-free approach: two category ticks with all-null data and a subtitle note under the chart, copy verbatim: the chart footnote "DfE didn't publish school-level figures for 2021/22" appears when the metric is a KS2 measure and 2021/22 school values are null while the England value exists). `spanGaps:false` on school datasets so dataset gaps break lines.
- [ ] **Step 4:** `TrendsExplorer` wraps the grouped metric picker (existing optgroup structure and `metrics` from `/api/metrics`, existing analytics event) + the chart + the existing year-by-year table, inside a collapsed-by-default `<details>` ("Explore trends"). Progress metrics annotate cells with `progressBand` chips for years where CIs exist.
- [ ] Tests pass; commit: `feat(compare): trends explorer with England line; fix missing series`
---
### Task 7: Assemble the new `ComparisonView`
**Files:**
- Rewrite: `nextjs-app/components/ComparisonView.tsx` (+ its `.module.css`)
- Modify: `nextjs-app/app/compare/page.tsx` metadata description (mention Ofsted/admissions, not just KS2)
- [ ] Preserve intact: `useComparison` basket seeding/URL sync (lines 76-122 of the current file), share handler, phase tabs + auto-detection, `compare_viewed` analytics, empty states, `SchoolSearchModal`, max-4-visible column scroll. Replace the metric-picker/chart/table body with the section stack: sticky school chip bar (mockup `.school-bar`) → `CompareAtAGlance``CompareOfsted``CompareAcademics``CompareAdmissions``CompareCommunity``TrendsExplorer`. The page-level `metric` URL param now initialises `TrendsExplorer`'s picker only.
- [ ] Top-of-page subtitle + sources footnote verbatim from the mockups (minus the "Mockup" banner), including the suppression rule sentence and provenance sentence.
- [ ] `npm test` full suite + `tsc` clean. Commit: `feat(compare): parent-first compare screen assembly`
---
### Task 8: e2e journeys (the promotion gate)
**Files:**
- Modify: `e2e/tests/journeys.spec.ts` (the two compare tests, lines ~141-215; extend, don't delete coverage)
- [ ] Update 'comparing two schools shows both side by side': after loading `/compare?urns=…` assert the new section headings (`At a glance`, `Ofsted inspection`, `How children do academically`, `Getting a place`, `Who goes there`, `Explore trends`), both school names in the sticky bar, at least one England-average tick label (`text=/England \d+%/`), and one provenance string `state-school average` somewhere (benchmarks row). Data-invariant style — no exact numbers (staging data shifts; use latest-year values only).
- [ ] Update the mobile test: 390px viewport, assert measure-first stacking (a `.measure`-card contains all selected school names within one card) and that the trends chart container scrolls (`overflow-x`).
- [ ] Add a report-card presence-agnostic assertion: the Ofsted section renders either a grade badge or "Report card" without an overall grade — i.e. never both an overall-grade badge AND report-card chips for the same school.
- [ ] Run against staging from the host if reachable (`cd e2e && BASE_URL=https://stx.schoolcompare.co.uk npx playwright test -g "compar"`) — staging still runs the OLD UI until this PR merges, so expect failures locally; the authoritative run is the Stage pipeline post-merge. Still commit only after jest+tsc are green.
- [ ] Commit: `test(e2e): compare journeys for the parent-first redesign`
---
### Task 9: PR + post-merge verification
- [ ] Full gates: `cd nextjs-app && npm test && npx tsc --noEmit`.
- [ ] Push; open PR via Gitea API (credential-helper basic auth). PR body: before/after summary, link to mockups + spec §4/§8, the copy-verbatim rule, the fixed third-series bug, deploy note (needs PR #34's API on the same environment — merge order: #34 first), and that the e2e suite is the staging gate.
- [ ] Post-merge: watch the Stage pipeline — its e2e run against staging is the real verification. Then the human tests staging and promotes (two-stage model). Update memory: compare redesign shipped to staging.
---
## Out of scope
- IDACI / attendance / gender-absence / finance (post-v1, spec §4).
- Backend changes of any kind (PR #34 must merge first).
- Chart palette overhaul beyond the England-line addition (`CHART_COLORS` swap to the validated trio is a candidate follow-up, flagged not included — it affects every chart in the app).

<h2 class="section-title">Ofsted inspection</h2>
<p class="how">Ofsted is the schools inspectorate. It stopped giving a single overall grade in <strong>September 2024</strong>; inspections between then and November 2025 kept the area-by-area judgements without an overall grade, and from <strong>November 2025</strong> new inspections produce a <strong>report card</strong> rating each area of school life on a five-point scale (Exceptional · Strong standard · Expected standard · Attention needed · Urgent improvement). A report card and an older overall grade aren't directly comparable — Plumcroft's report card below is an <em>illustrative example</em> of the new format, as no school in our dataset has one yet. (Ofsted's "Expected standard" rating is unrelated to the KS2 "expected standard" test measure further down this page.)</p>

Sources: DfE Compare School Performance (KS2 results), Ofsted inspection outcomes, DfE school admissions data, school census — all from datasets SchoolCompare already collects. England averages for test results are the official DfE national figures; benchmarks for free school meals, language, SEN, school size and disadvantaged pupils' results are computed across all state schools in our dataset. Following DfE practice, figures based on 5 or fewer pupils are suppressed and shown as "no data". This is a static mockup: tooltips and "Add school" are illustrative, and Plumcroft's Ofsted report card is a made-up example of the November 2025 format (its real latest inspection is Good, June 2023) — no school in our dataset has a report card yet.

<p class="how">Ofsted stopped giving a single overall grade in September 2024 (inspections until November 2025 kept the area-by-area judgements); from November 2025 new inspections produce a report card rating each area of school life (Exceptional · Strong standard · Expected standard · Attention needed · Urgent improvement). A report card and an older grade aren't directly comparable. Ofsted's "Expected standard" rating is unrelated to the KS2 test measure below.</p>

Sources: DfE Compare School Performance, Ofsted inspection outcomes, DfE admissions data, school census — all from datasets SchoolCompare already collects. England averages for test results are official DfE figures; FSM, language, SEN, size and disadvantaged-pupil benchmarks are computed across state schools in our dataset. Plumcroft's Ofsted report card is a made-up example of the November 2025 format (its real latest inspection is Good, June 2023). Following DfE practice, figures based on 5 or fewer pupils are suppressed and shown as "no data". Static mockup — tooltips and "+ Add" are illustrative.
