+# School Type Groups and a Faith Filter 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:** Replace the School type filter's 34 GIAS types with six parent-facing groups, and add a Faith filter with eight options.
+
+**Architecture:** A new backend module `backend/school_groups.py` holds both groupings as GIAS code sets and exposes lookups by the translated *name* (the DataFrame the API filters only carries names). `/api/schools` accepts a group key for `school_type` and a new `faith` key; `/api/filters` gains `school_type_groups` and `faiths` as `{value, label}` lists. The frontend's FilterBar reads those lists for its School type select and a new Faith select.
+
+**Tech Stack:** FastAPI + pandas (backend, pytest via uv), Next.js 15 / React (frontend, Jest + Testing Library), Playwright (E2E against staging).
+
+**Spec:** `docs/superpowers/specs/2026-10-02-school-type-groups-and-faith-filter-design.md`
+
+## Global Constraints
+
+- Type group keys, labels and order, verbatim: `academy` "State school: academy or free school", `council` "State school: council-run", `independent` "Independent (fee-paying)", `special` "Special school (SEND)", `post16` "Sixth form or college", `alternative` "Alternative provision".
+- Faith keys, labels and order, verbatim: `none` "No religious character", `church_of_england` "Church of England", `roman_catholic` "Roman Catholic", `other_christian` "Other Christian", `jewish` "Jewish", `muslim` "Muslim", `other_faith` "Other faith".
+- Select defaults, verbatim: "Any school type", "Any faith or none". Faith select `aria-label="Faith"`.
+- `/api/filters` keeps `school_types` (raw list) unchanged; the new keys are additions.
+- An old raw-label `school_type` value (e.g. `Community school`) still filters by that label exactly.
+- An unknown `faith` key returns no schools.
+- Do not change `backend/gias_codes.py` or `pipeline/scripts/gias_codes.py` (their parity is tested).
+- No copy may use an em dash (`__tests__/components/noEmDashCopy.test.ts`).
+- Backend tests run from the repo root with: `uv run --with-requirements requirements.txt --with pytest --with "httpx==0.27.0" python -m pytest backend/tests -q`
+- Frontend checks run from `nextjs-app/`: `npx jest` and `npx tsc --noEmit`.
+- Do not start a local server. E2E journeys are verified against staging after merge.
+
+## Review Focus
+
+- A school whose `religious_denomination` is `None`/NaN or `""` (GIAS code 99) must count as "No religious character", not drop out of every faith option. Pinned in Task 1.
+- A type or religion label the dictionaries do not know (e.g. `"Unknown (9999)"`, or a test fixture's `"Academy"`) must map to no group without raising. Pinned in Task 1.
+- `/api/filters` returning no `school_type_groups`/`faiths` (API failed, or an older backend) must leave the selects out rather than render "Any…" alone. Pinned in Task 3.
+- An old bookmarked URL with `school_type=Community+school` must still return community schools and show a chip with its raw label. Pinned in Tasks 2 and 3.
+- Mixed case in a key (`?faith=Roman_Catholic`, `?school_type=Special`) must still match. Pinned in Task 2.
+
+---
+
+## File Structure
+
+| File | Responsibility |
+|---|---|
+| `backend/school_groups.py` (new) | The two groupings as code sets, and name-based lookups. Nothing else. |
+| `backend/tests/test_school_groups.py` (new) | Coverage of every GIAS code, joint faiths, unknown/blank names. |
+| `backend/app.py` (modify) | `faith` param; group-key branch for `school_type`; two new `/api/filters` keys. |
+| `backend/tests/test_type_and_faith_filters.py` (new) | API behaviour of both filters and the new `/api/filters` keys. |
+| `nextjs-app/lib/types.ts` (modify) | `FilterOption`; optional `school_type_groups`/`faiths` on `Filters`; `faith` on `SchoolSearchParams`. |
+| `nextjs-app/app/(frontend)/page.tsx` (modify) | Read and forward `faith`. |
+| `nextjs-app/components/FilterBar.tsx` (modify) | Grouped School type options; Faith select; chips, counts, analytics. |
+| `nextjs-app/__tests__/components/FilterBarTypeFaith.test.tsx` (new) | Frontend behaviour of both selects. |
+| Existing FilterBar tests (modify) | Fixtures move from raw types to groups. |
+| `e2e/tests/journeys.spec.ts` (modify) | A journey for both filters. |
+| Spec (modify) | Architecture section: grouping is by name at filter time. |

+
+### Task 1: The groupings module
+
+**Files:**
+- Create: `backend/school_groups.py`
+- Test: `backend/tests/test_school_groups.py`
+- Modify: `docs/superpowers/specs/2026-10-02-school-type-groups-and-faith-filter-design.md` (Architecture)
+
+**Interfaces:**
+- Consumes: `backend.gias_codes.SCHOOL_TYPE: dict[int, str]`, `backend.gias_codes.RELIGIOUS_CHARACTER: dict[int, str]` (code 99 maps to `""`).
+- Produces:
+  - `TYPE_GROUPS: tuple[tuple[str, str, frozenset[int]], ...]` (key, label, codes), in display order
+  - `UNOFFERED_TYPE_CODES: frozenset[int]`
+  - `FAITH_GROUPS: tuple[tuple[str, str, frozenset[int]], ...]`, in display order

+
+The groups are defined over codes but looked up by the translated name
+(`type_group_for(name)`, `faith_groups_for(name)`), when `/api/schools` and
+`/api/filters` filter. The DataFrame those endpoints read carries names only:
+`translate_gias_code_columns` replaces the codes at load, the legacy-name
+mart fallback never had codes, and the API test fixtures are written in
+names. The names come from the same dictionaries, so the lookup is exact.
+`data_loader.py` is unchanged.
+```
+
+and in `### backend/school_groups.py (new)` replace the `type_group_for(code)` / `faith_groups_for(code)` bullet with `type_group_for(name) -> str | None` and `faith_groups_for(name) -> tuple[str, ...]` (a missing or blank name gives `("none",)`).

+- [ ] **Step 2: Run them to see them fail**
+
+Run: `uv run --with-requirements requirements.txt --with pytest --with "httpx==0.27.0" python -m pytest backend/tests/test_type_and_faith_filters.py -q`
+Expected: the group-key, faith and `/api/filters` tests fail (`KeyError: 'school_type_groups'`, empty URN lists); `test_a_raw_type_label_still_filters_exactly` passes.
+
+- [ ] **Step 3: Implement**
+
+In `backend/app.py`, add beside the other local imports (after the `from .schemas import ...` line):
+
+```python
+from .school_groups import (
+    FAITH_GROUPS,
+    FAITH_KEYS,
+    TYPE_GROUP_KEYS,
+    TYPE_GROUPS,
+    faith_groups_for,
+    type_group_for,
+)
+```
+
+Add a helper just above `def sanitize_search_input`:
+
+```python
+def _names_in_group(names: pd.Series, in_group) -> set:
+    """The distinct names in a column that a group predicate accepts.
+
+    Evaluated once per distinct name rather than per row, so a filter over
+    every school costs a few dozen lookups.
+    """
+    return {n for n in names.dropna().unique() if in_group(n)}
+```
+
+In `get_schools`, add the parameter after `has_sixth_form`:
+
+```python
+    faith: Optional[str] = Query(None, description="Filter by faith group key", max_length=40),
+```
+
+and after `phase = sanitize_search_input(phase)`:
+
+```python
+    faith = sanitize_search_input(faith)
+```
+
+After the `has_sixth_form` filter block (the one ending `df_latest = df_latest[flag if has_sixth_form == "yes" else ~flag]`), add:
+
+```python
+    # Faith group (backend/school_groups.py). A joint school is in every faith
+    # its label names; a missing religious character is "none". An unknown key
+    # matches nothing rather than being ignored, so a typo cannot show all.
+    if faith:
+        faith_key = faith.lower()
+        if faith_key in FAITH_KEYS and "religious_denomination" in df_latest.columns:
+            column = df_latest["religious_denomination"]
+            matches = column.isin(_names_in_group(column, lambda n: faith_key in faith_groups_for(n)))
+            # _names_in_group skips missing names; a missing religious
+            # character is "No religious character".
+            if faith_key == "none":
+                matches = matches | column.isna()

+        else:
+            df_latest = df_latest.iloc[0:0]
+```
+
+Replace the existing `school_type` filter:
+
+```python
+    if school_type:
+        schools_df = schools_df[
+            schools_df["school_type"].str.lower() == school_type.lower()
+        ]
+```
+
+with:
+
+```python
+    # A type group key (backend/school_groups.py), or for an old link a raw
+    # GIAS type label, matched exactly as before.
+    if school_type:
+        type_key = school_type.lower()
+        if type_key in TYPE_GROUP_KEYS:
+            column = schools_df["school_type"]
+            schools_df = schools_df[

+        else:
+            schools_df = schools_df[schools_df["school_type"].str.lower() == type_key]
+```
+
+In `get_filter_options`, add to the early `if df.empty:` return dict:
+
+```python
+            "school_type_groups": [],
+            "faiths": [],
+```
+
+and before the final `return {`:
+
+```python
+    def offered(groups, present):
+        return [{"value": key, "label": label} for key, label, _ in groups if key in present]
+
+    type_groups_present = (
+        {type_group_for(n) for n in df["school_type"].dropna().unique()} - {None}
+        if "school_type" in df.columns else set()
+    )
+    faiths_present = (
+        {f for n in df["religious_denomination"].unique() for f in faith_groups_for(n)}
+        if "religious_denomination" in df.columns else set()
+    )
+```
+
+and add to the returned dict:
+
+```python
+        "school_type_groups": offered(TYPE_GROUPS, type_groups_present),
+        "faiths": offered(FAITH_GROUPS, faiths_present),
+```
+
+- [ ] **Step 4: Run the new tests, then the whole backend suite**
+
+Run: `uv run --with-requirements requirements.txt --with pytest --with "httpx==0.27.0" python -m pytest backend/tests/test_type_and_faith_filters.py -q`
+Expected: all pass.

+
+**Files:**
+- Modify: `nextjs-app/lib/types.ts` (`Filters` ~487-494, `SchoolSearchParams` ~558-570)
+- Modify: `nextjs-app/app/(frontend)/page.tsx` (props type ~15-29, `hasSearchParams` ~79-88, `fetchSchools` call ~96-109)

+- Test: `nextjs-app/__tests__/components/FilterBarTypeFaith.test.tsx` (new)
+- Modify tests: `__tests__/components/ResultsToolbar.test.tsx`, `FilterSheet.test.tsx`, `FilterSheetPending.test.tsx`, `FilterBarOptions.test.tsx`
+
+**Interfaces:**
+- Consumes: `/api/filters` keys `school_type_groups`, `faiths` (Task 2); URL params `school_type` (group key) and `faith`.
+- Produces: `export interface FilterOption { value: string; label: string }`; `Filters.school_type_groups?: FilterOption[]`; `Filters.faiths?: FilterOption[]`; `SchoolSearchParams.faith?: string`. FilterBar selects named "School type" and "Faith".
+
+- [ ] **Step 1: Write the failing tests**
+

+```
+
+- [ ] **Step 2: Run them to see them fail**
+
+Run (from `nextjs-app/`): `npx jest __tests__/components/FilterBarTypeFaith.test.tsx`
+Expected: failures; School type still lists `Community school`, no `Faith` combobox. (`tsc` also flags `school_type_groups` on `Filters`, which Step 3 fixes.)
+
+- [ ] **Step 3: Types and page plumbing**
+
+In `nextjs-app/lib/types.ts`, above `export interface Filters`:
+
+```ts
+/** A filter option whose URL value differs from what a parent reads. */
+export interface FilterOption {
+  value: string;
+  label: string;
+}
+```
+
+and add to `Filters` (after `admissions_policies`):
+
+```ts
+  /** Parent-facing school type groups; the URL's school_type takes their value. */
+  school_type_groups?: FilterOption[];
+  faiths?: FilterOption[];
+```
+
+and to `SchoolSearchParams` (after `has_sixth_form`):
+
+```ts
+  faith?: string;
+```
+
+In `nextjs-app/app/(frontend)/page.tsx`: add `faith?: string;` to the `searchParams` type after `has_sixth_form?: string;`; add `params.faith ||` to `hasSearchParams` after `params.has_sixth_form`; add `faith: params.faith,` to the `fetchSchools({...})` call after `has_sixth_form: params.has_sixth_form,`.
+
+- [ ] **Step 4: FilterBar**
+
+In `nextjs-app/components/FilterBar.tsx`:
+
+1. Add `"faith"` to `FILTER_KEYS` directly after `"school_type"`.
+2. After `const currentHasSixthForm = ...` add:
+
+```tsx
+  const currentFaith = searchParams.get("faith") || "";
+```
+
+3. Add `currentFaith,` to the `activeDropdownFilters` array (after `currentLA,`). Faith lives behind More filters, so it counts there.
+4. In `handleSearchSubmit`'s `filters_active` list, after the `type=` line add:
+
+```tsx
+      currentFaith && `faith=${currentFaith}`,
+```
+
+5. Add `currentFaith ||` to `hasActiveFilters` after `currentType ||`.
+6. Replace `const typeOptions = filters.school_types;` with:
+
+```tsx
+  // Six groups a parent recognises, not GIAS's 34 establishment types.
+  const typeOptions = filters.school_type_groups ?? [];
+  const faithOptions = filters.faiths ?? [];
+```
+
+7. Add `faith: currentFaith,` to the `values` record after `school_type: currentType,`.
+8. In `labelFor`, before the `// Phase, gender and admissions values…` comment, add:
+
+```tsx
+    // An old link may carry a raw GIAS type, which reads as itself.
+    const labelled = { school_type: typeOptions, faith: faithOptions }[
+      key as "school_type" | "faith"
+    ];
+    if (labelled) return labelled.find((o) => o.value === value)?.label ?? value;
+```
+
+9. In `typeSelect`, replace the options map with:
+
+```tsx
+        {typeOptions.map((o) => (
+          <option key={o.value} value={o.value}>
+            {o.label}
+          </option>
+        ))}
+```
+
+10. After `laSelect`, add:
+
+```tsx
+  const faithSelect = (look: Look) => (
+    <SelectShell wide>
+      <select
+        value={currentFaith}
+        onChange={(e) => handleFilterChange("faith", e.target.value)}
+        className={selectClass(look, currentFaith)}
+        aria-label="Faith"
+        disabled={isPending && look !== "sheet"}
+      >
+        <option value="">Any faith or none</option>
+        {faithOptions.map((o) => (
+          <option key={o.value} value={o.value}>
+            {o.label}
+          </option>
+        ))}
+      </select>
+    </SelectShell>
+  );
+```
+
+11. In the desktop row, change `{typeSelect("pill")}` to `{typeOptions.length > 0 && typeSelect("pill")}`.
+12. In the More filters panel, after `{laSelect("panel")}` add `{faithOptions.length > 0 && faithSelect("panel")}`.
+13. In the sheet, replace `<SheetField label="School type">{typeSelect("sheet")}</SheetField>` with:
+
+```tsx
+            {typeOptions.length > 0 && (
+              <SheetField label="School type">{typeSelect("sheet")}</SheetField>
+            )}
+            {faithOptions.length > 0 && (
+              <SheetField label="Faith">{faithSelect("sheet")}</SheetField>
+            )}
+```
+
+- [ ] **Step 5: Move the existing tests' fixtures to groups**
+
+These tests used raw types as values; give each fixture the groups and use keys:
+
+- `ResultsToolbar.test.tsx`: add to `filters` `school_type_groups: [{ value: 'council', label: 'State school: council-run' }],`; in 'counts only what More filters hides' change `school_type=Community+school` to `school_type=council`.
+- `FilterSheet.test.tsx`: add the same `school_type_groups` to `filters`; change both `school_type=Community+school` to `school_type=council`.
+- `FilterSheetPending.test.tsx`: add the same `school_type_groups`; change the `{ target: { value: 'Community school' } }` to `{ target: { value: 'council' } }` and `toBe('Community school')` to `toBe('council')`.
+- `FilterBarOptions.test.tsx`: add to `filters` `school_type_groups: [{ value: 'academy', label: 'State school: academy or free school' }, { value: 'council', label: 'State school: council-run' }],`; change `school_type=Community+school` (two places) to `school_type=council`; change the expected School type options to `['Any school type', 'State school: academy or free school', 'State school: council-run']`; change `toBe('Community school')` to `toBe('council')`; rename the first test to 'offer every school type group, gender and admissions policy, whatever the results hold'; and in the header comment replace "School type, gender and admissions offer the full lists" with "School type groups, gender and admissions offer the full lists".
+
+- [ ] **Step 6: Run the frontend checks**
+
+Run (from `nextjs-app/`): `npx jest` then `npx tsc --noEmit`
+Expected: all suites pass; no type errors.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add nextjs-app/lib/types.ts "nextjs-app/app/(frontend)/page.tsx" nextjs-app/components/FilterBar.tsx nextjs-app/__tests__/components/FilterBarTypeFaith.test.tsx nextjs-app/__tests__/components/ResultsToolbar.test.tsx nextjs-app/__tests__/components/FilterSheet.test.tsx nextjs-app/__tests__/components/FilterSheetPending.test.tsx nextjs-app/__tests__/components/FilterBarOptions.test.tsx

+# School Type Groups and a Faith Filter — Design
+
+**Date:** 2026-10-02
+**Status:** shipped in PR #170; revised 2026-10-02 (one state group)
+**Scope:** search filters (`/` results toolbar and phone filter sheet), `/api/schools`, `/api/filters`
+
+## Goal
+
+Replace the School type filter's 34 GIAS establishment types with five groups a
+parent recognises, and add a Faith filter.
+
+> **Revision, 2026-10-02.** PR #170 shipped six groups, with state schools
+> split into "academy or free school" and "council-run". They are now one,
+> "State school (free)". The split was two near-halves of the same pool, so it
+> rarely narrowed anything, and it did not follow the difference a parent feels
+> most, admissions: voluntary aided and foundation schools set their own
+> admissions, as academies do, while community and voluntary controlled
+> schools have theirs set by the council. Faith, which voluntary aided mostly
+> meant, has its own filter. The old keys `academy` and `council` resolve to
+> `state`, so their links keep working.
+
+Since PR #169 the School type select offers the full GIAS list rather than the
+types in the results. That fixed the trap where choosing a type left only that
+type on offer, but it exposed the list itself: "Academy converter", "Academy
+sponsor led", "Free schools", "Foundation school", "Voluntary controlled
+school" and 29 more. These describe governance and funding. For a mainstream
+state school they change almost nothing a parent experiences, and parents
+cannot be expected to know the differences.
+
+What parents actually ask is: is it free, is it mainstream, is it for children
+with special needs, is it a sixth form or college, and is it a faith school.
+The first four are the type groups below. The fifth is the real meaning behind
+"Voluntary aided" and "Voluntary controlled", but many academies are faith
+schools too, so it gets its own filter rather than hiding inside type.
+
+## Non-goals
+
+- Changing what a school page or result row shows. They keep the precise GIAS
+  type ("Academy sponsor led"), where it is information, not a choice.
+- Removing the "not offered" types from search results. They stay reachable
+  under "Any school type"; whether parents should see them at all is a
+  separate decision.
+- Reordering the type options by phase (for example "Sixth form or college"
+  first for 16 plus). Fixed order is simpler.
+- The rankings page, which has no type filter.
+- Changing `result_filters`. Its `school_types` key is already unread
+  (docs/LEGACY_CODE.md).
+
+## Type groups
+
+Order is the order shown. Codes are GIAS `TypeOfEstablishment` codes
+(`backend/gias_codes.py: SCHOOL_TYPE`). Counts are staging schools on
+2026-10-02.
+
+| Key | Label | GIAS codes | Schools |
+|---|---|---|---|
+| `state` | State school (free) | 28 Academy sponsor led, 34 Academy converter, 35 Free schools, 40 University technical college, 41 Studio schools, 6 City technology college, 1 Community school, 2 Voluntary aided school, 3 Voluntary controlled school, 5 Foundation school, 15 Local authority nursery school | 20,502 |
+| `independent` | Independent (fee-paying) | 11 Other independent school | 1,585 |
+| `special` | Special school (SEND) | 7 Community special, 12 Foundation special, 44 Academy special converter, 33 Academy special sponsor led, 36 Free schools special, 8 Non-maintained special, 10 Other independent special, 32 Special post 16 institution | 2,227 |
+| `post16` | Sixth form or college | 18 Further education, 31 Sixth form centres, 45 Academy 16-19 converter, 46 Academy 16 to 19 sponsor led, 39 Free schools 16 to 19 | 302 |
+| `alternative` | Alternative provision | 14 Pupil referral unit, 42 Academy AP converter, 43 Academy AP sponsor led, 38 Free schools AP | 331 |
+
+**Not offered** (no group, reachable only under "Any school type"): 29 Higher
+education institutions, 27 Miscellaneous, 24 Secure units, 49 Online provider,
+57 Academy secure 16 to 19, 56 Institution funded by other government
+department. 238 schools.
+
+**Excluded upstream** (never in the marts): 25, 26, 30, 37, per
+`non_england_school_type_codes` in `pipeline/transform/dbt_project.yml`.
+
+### Judgement calls
+
+- **Independent special schools are Special, not Independent.** They are
+  usually funded by the local authority through a child's EHCP; to a parent
+  they are SEND provision, not private school.
+- **UTCs, studio schools and city technology colleges are state schools.** They
+  are legally academies, they are few (66 together), and a family considering
+  one searches for it by name.
+- **Academies and council-run schools are one group.** See the revision note
+  under Goal.
+- **Special post 16 institutions are Special, not Sixth form or college.** The
+  defining fact for a parent is the SEND provision.
+- **Alternative provision is last.** Parents do not apply to it; the local
+  authority places children there.
+
+## Faith groups
+
+Codes are GIAS `ReligiousCharacter` codes
+(`backend/gias_codes.py: RELIGIOUS_CHARACTER`). A joint school belongs to every
+faith its label names, so "Roman Catholic/Church of England" matches both
+Church of England and Roman Catholic. A generic "Christian" alongside a named
+denomination adds nothing ("Church of England/Christian" is Church of England
+only).
+
+| Key | Label | GIAS codes |
+|---|---|---|
+| `none` | No religious character | 0 Does not apply, 6 None, 99 (blank), and a missing code |
+| `church_of_england` | Church of England | 2, 31 Anglican, 34 Anglican/Church of England, 20 CofE/Christian, 32 Anglican/Christian, and the joint codes 9, 10, 11, 12, 13, 19, 30, 33, 41, 48 |
+| `roman_catholic` | Roman Catholic | 3, 35 Catholic, and the joint codes 11, 13, 48 |
+| `other_christian` | Other Christian | 4 Methodist, 8 Seventh Day Adventist, 14 Quaker, 15 Christian, 16 United Reformed Church, 17 Congregational Church, 18 Free Church, 22 Greek Orthodox, 26 Moravian, 28 Inter- / non- denominational, 37 Christian/Evangelical, 38 Christian Science, 39 Christian/Methodist, 40 Christian/non-denominational, 44 Plymouth Brethren Christian Church, 45 Protestant, 46 Protestant/Evangelical, 47 Reformed Baptist, and the joint codes 9, 10, 12, 19, 30, 33, 41 |
+| `jewish` | Jewish | 5 Jewish, 36 Charadi Jewish, 43 Orthodox Jewish |
+| `muslim` | Muslim | 7 Muslim, 42 Islam, 49 Sunni Deobandi |
+| `other_faith` | Other faith | 21 Sikh, 24 Buddhist, 25 Hindu, 29 Multi-faith |
+
+The joint codes: 9 CofE/Methodist, 10 Methodist/CofE, 11 CofE/RC, 12 CofE/URC,
+13 RC/CofE, 19 CofE/Free Church, 30 CofE/Methodist/URC/Baptist,
+33 Anglican/Evangelical, 41 CofE/Evangelical, 48 RC/Anglican.
+
+28 "Inter- / non- denominational" is filed as Other Christian: GIAS uses it for
+Christian schools that are not tied to one church.
+
+## Architecture
+
+Grouping lives in the backend, not dbt. The API already translates GIAS codes
+to names when it loads the marts (`backend/data_loader.py:
+translate_gias_code_columns`), and every filter is applied to that DataFrame.
+Grouping there needs no mart change, so there is no Airflow run between merge
+and staging showing it.
+
+### `backend/school_groups.py` (new)
+
+- `TYPE_GROUPS`: ordered `(key, label, frozenset[int])` per type group.
+- `UNOFFERED_TYPE_CODES`: the not-offered codes, so that "every code is
+  accounted for" is testable.
+- `FAITH_GROUPS`: ordered `(key, label, frozenset[int])` per faith group.
+- `type_group_for(name) -> str | None` and
+  `faith_groups_for(name) -> tuple[str, ...]` (a missing or blank name gives
+  `("none",)`).
+
+No dependence on the generated GIAS dictionaries beyond their codes, so the
+backend/pipeline dictionary parity test is untouched.
+
+### Grouping by name, at filter time
+
+The groups are defined over codes but looked up by the translated name
+(`type_group_for(name)`, `faith_groups_for(name)`), when `/api/schools` and
+`/api/filters` filter. The DataFrame those endpoints read carries names only:
+`translate_gias_code_columns` replaces the codes at load, the legacy-name
+mart fallback never had codes, and the API test fixtures are written in
+names. The names come from the same dictionaries, so the lookup is exact.
+`data_loader.py` is unchanged.
+
+### `/api/schools`
+
+Both filters work on the name columns at request time. `_names_in_group`
+collects the distinct `school_type` or `religious_denomination` names the
+group accepts, once per distinct name rather than per row, and the rows are
+kept with `isin`. No group column is stored.
+
+- `school_type`: if the value is a type group key (any case), keep the rows
+  whose `school_type` name `type_group_for` puts in that group. Otherwise
+  filter on the raw label exactly as today, so an old
+  `?school_type=Community+school` link keeps working.
+- `faith` (new, optional, `max_length=40`, sanitised like the others): keep the
+  rows whose `religious_denomination` name `faith_groups_for` puts in that
+  faith (any case); for `none`, rows with a missing name too. An unknown key
+  returns no schools rather than being ignored, so a typo does not silently
+  show everything.
+
+### `/api/filters`
+
+Two new keys:
+
+- `school_type_groups`: `[{value, label}]` in `TYPE_GROUPS` order, only groups
+  with at least one school.
+- `faiths`: `[{value, label}]` in `FAITH_GROUPS` order, same rule.
+
+`school_types` stays as it is (the raw list), so nothing that reads it breaks.
+
+### Frontend
+
+- `lib/types.ts`: `Filters` gains optional `school_type_groups` and `faiths`
+  (`{ value: string; label: string }[]`). Optional, so the empty fallbacks in
+  `app/(frontend)/page.tsx` and `rankings/page.tsx` stay valid.
+- `app/(frontend)/page.tsx`: reads `faith` from the search params, counts it
+  in `hasSearchParams`, and passes it to `fetchSchools`. `SchoolSearchParams`
+  in `lib/types.ts` gains `faith`. HomeView's load-more already forwards every
+  URL param. HomeView's `isSearchActive` is left as it is: like phase and
+  gender, faith narrows a search rather than starting one.
+- `components/FilterBar.tsx`:
+  - The School type select's options become `filters.school_type_groups`;
+    "Any school type" stays first. With no groups (the API failed), the select
+    is left out, as Gender and Admissions already are.
+  - A new **Faith** select (`aria-label="Faith"`, "Any faith or none" first)
+    from `filters.faiths`. On desktop it goes in the More filters panel, after
+    Local authority. In the phone sheet it comes after School type.
+  - `faith` joins `FILTER_KEYS` (chip and Filters count) and the More filters
+    count, and `faith=` joins `filters_active` in the `search_submitted`
+    analytics event.
+  - Chip labels come from the option lists: "Special school (SEND)",
+    "Roman Catholic". An old raw-label `school_type` shows its raw label.
+- `lib/utils.ts: isSpecialSchool` is unchanged. It reads a school's raw
+  `school_type`, which still arrives.
+
+## Testing
+
+**Backend (pytest):**
+
+- Every `SCHOOL_TYPE` code is in exactly one type group, in
+  `UNOFFERED_TYPE_CODES`, or in `non_england_school_type_codes`. A new DfE
+  code fails this test instead of silently vanishing from the filter.
+- Every `RELIGIOUS_CHARACTER` code maps to at least one faith group.
+- The joint codes map to each faith they name (11 and 48 → CofE and RC;
+  9 → CofE and Other Christian) and 20 → CofE only.
+- `/api/schools?school_type=special` returns only special-group schools;
+  `?school_type=Community+school` still filters by label.
+- `/api/schools?faith=roman_catholic` returns only matching schools, a joint
+  school included; `?faith=nonsense` returns none.
+- `/api/filters` lists the groups in order and leaves out an empty one.
+- Run via uv, as the backend tests always are.
+
+**Frontend (Jest):**
+
+- School type offers the six group labels, not raw types.
+- Faith offers its options, in the panel and in the sheet.
+- A faith filter shows as a chip, counts on Filters and More filters, and
+  clears with Clear all.
+- No groups or faiths in `filters` → the select is left out.
+
+**E2E (`e2e/tests/journeys.spec.ts`):**
+
+- A journey that picks "Special school (SEND)" and "Roman Catholic" from the
+  selects, then checks through `/api/schools` with the same params that every
+  returned school's `school_type` is a special type and its
+  `religious_denomination` names Catholic. Data-invariant: it asserts the
+  property, not a count.
+- It can only pass after merge; the staging E2E gate runs post-merge.
+
+## Rollout
+
+One PR; backend and frontend deploy together on merge. The frontend tolerates
+an API without the new keys (the selects are left out), so the order the
+containers update in does not matter.
