+# Reference-Data Scannability + Parity — 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:** Make the three reference-data lists scannable (locale-aware sort + filter), show `external_uri` in read rows, add field-group count badges, and close the small parity/validation gaps — no layout/edit-modality change, no backend change.
+
+**Architecture:** A shared `lib/sort.ts` (memoized `Intl.Collator` comparators) + a tiny `ExternalUriLink` are consumed by the vocab/authorities/fields list components. Each list gets a client-side filter `useState` + `<Input>`; rows are filtered then sorted before render.
+
+**Tech Stack:** React 19 + TS + pnpm, react-i18next, Vitest + RTL + MSW. Test runner: `pnpm test` (single pass).
+
+**Conventions:** pnpm; **no `any`/`eslint-disable`/`@ts-ignore`**; no codename; en/sv parity (3 new keys); app source double-quote+semicolon; token classes only; **don't mutate query-cache arrays — sort a copy** (`[...list].sort(...)`).
+
+**Spec:** `docs/superpowers/specs/2026-06-08-refdata-scannability-design.md`
+
+**Key facts (from the code):**
+- `labelText(labels, lang)` in `lib/labels.ts`. `lang = i18n.language.startsWith("sv") ? "sv" : "en"`.
+- term/authority view = `{ id, labels, external_uri?: string|null }` (authority also `kind`); vocabulary = `{ id, key }`; field-def = `{ key, labels, data_type, group?, required, … }`.
+- `term-row.tsx`/`authority-row.tsx`: read mode `<span className="flex-1">{labelText(...)}</span>` + Edit + DeleteConfirmDialog; edit mode has the `external_uri` `<Input>` (no `type`/placeholder).
+- `vocabulary-list.tsx`: create form (has empty-guard) + list; rename `<form onSubmit>` calls `renameVocabulary.mutate({ id, key: draftKey.trim() })` with NO empty-guard.
+- `authorities-page.tsx`: tabs + list + create form; create calls `create.mutate({ kind, external_uri: null, labels })` — hardcoded null, no URI field.
+- `field-list.tsx`: groups built into a `Map`; sorted with `t("fields.other")` last (no A–Z); group header `<div className="… label-caption">{group}</div>`; rows show label+key+type+required.
+- `common` i18n: `{ yes, no, close, loading }`. `labels`: `{ label, externalUri, otherLanguages }`.
+
+---
+
+# Task 1: Shared `sort.ts` + `ExternalUriLink` + i18n + unit test
+
+**Files:** `web/src/lib/sort.ts` (new), `web/src/lib/sort.test.ts` (new), `web/src/components/external-uri-link.tsx` (new), `web/src/i18n/en.json`, `web/src/i18n/sv.json`.
+
+- [ ] **Step 1: i18n (both locales, parity).**
+  - `common`: add `"filter"` (en "Filter…" / sv "Filtrera…") and `"noMatches"` (en "No matches" / sv "Inga träffar").
+  - `labels`: add `"uriPlaceholder": "https://…"` (same string in both).
+
+- [ ] **Step 2: `web/src/lib/sort.ts`:**
+```ts
+import type { components } from "../api/schema";
+
+import { labelText } from "./labels";
+
+type LabelView = components["schemas"]["LabelView"];
+
+const collators = new Map<string, Intl.Collator>();
+
+function collatorFor(lang: string): Intl.Collator {
+  let c = collators.get(lang);
+  if (!c) {
+    c = new Intl.Collator(lang, { sensitivity: "base", numeric: true });
+    collators.set(lang, c);
+  }
+  return c;
+}
+
+export function compareStrings(lang: string, a: string, b: string): number {
+  return collatorFor(lang).compare(a, b);
+}
+
+export function byLabel(lang: string) {
+  return (a: { labels: LabelView[] }, b: { labels: LabelView[] }) =>
+    compareStrings(lang, labelText(a.labels, lang), labelText(b.labels, lang));
+}
+
+export function byKey(lang: string) {
+  return (a: { key: string }, b: { key: string }) => compareStrings(lang, a.key, b.key);
+}
+```
+
+- [ ] **Step 3: `web/src/lib/sort.test.ts`** (write failing first, then it passes with Step 2):
+```ts
+import { expect, test } from "vitest";
+import { byKey, byLabel, compareStrings } from "./sort";
+
+const L = (label: string) => ({ labels: [{ lang: "en", label }] });
+
+test("byLabel sorts case-insensitively and locale-aware", () => {
+  const sorted = [L("Iron"), L("bronze"), L("Amber")].sort(byLabel("en")).map((x) => x.labels[0].label);
+  expect(sorted).toEqual(["Amber", "bronze", "Iron"]);
+});
+
+test("byKey sorts keys with numeric awareness", () => {
+  const sorted = [{ key: "item10" }, { key: "item2" }, { key: "item1" }].sort(byKey("en")).map((x) => x.key);
+  expect(sorted).toEqual(["item1", "item2", "item10"]);
+});
+
+test("compareStrings is case-insensitive", () => {
+  expect(compareStrings("en", "bronze", "BRONZE")).toBe(0);
+});
+```
+Run: `cd web && pnpm vitest run src/lib/sort.test.ts` → PASS (3 tests).
+
+- [ ] **Step 4: `web/src/components/external-uri-link.tsx`** (app-source style):
+```tsx
+export function ExternalUriLink({ uri }: { uri: string }) {
+  return (
+    <a
+      href={uri}
+      target="_blank"
+      rel="noopener noreferrer"
+      className="block truncate text-xs text-muted-foreground hover:text-foreground"
+    >
+      {uri}
+    </a>
+  );
+}
+```
+
+- [ ] **Step 5: Verify (vitest ONCE):** `cd web && pnpm vitest run src/lib/sort.test.ts && pnpm typecheck && pnpm lint`. PASS, clean.
+
+- [ ] **Step 6: Commit**
+```bash
+git add web/src/lib/sort.ts web/src/lib/sort.test.ts web/src/components/external-uri-link.tsx web/src/i18n/en.json web/src/i18n/sv.json
+git commit -m "feat(web): collator sort helpers + ExternalUriLink + filter/uri i18n (#50)"
+```
+
+---
+
+# Task 2: Vocabularies — filter + sort + URI + rename guard
+
+**Files:** `web/src/vocab/vocabulary-list.tsx`, `web/src/vocab/vocabulary-terms.tsx`, `web/src/vocab/term-row.tsx`, `web/src/vocab/vocabularies.test.tsx`.
+
+- [ ] **Step 1: `vocabulary-list.tsx`** — add `i18n` to `useTranslation` (`const { t, i18n } = …`) and `const lang = i18n.language.startsWith("sv") ? "sv" : "en";`; import `byKey` from `../lib/sort` and `Input` is already imported. Add `const [filter, setFilter] = useState("");`.
+  - Add a filter `<Input>` between the create `<form>` and the list block:
+```tsx
+<div className="border-b p-2">
+  <Input
+    aria-label={t("common.filter")}
+    placeholder={t("common.filter")}
+    value={filter}
+    onChange={(e) => setFilter(e.target.value)}
+  />
+</div>
+```
+  - In the loaded `<ul>`, replace `{data?.map((v) => (…` with a filtered+sorted list:
+```tsx
+{(() => {
+  const q = filter.trim().toLowerCase();
+  const rows = [...(data ?? [])]
+    .filter((v) => !q || v.key.toLowerCase().includes(q))
+    .sort(byKey(lang));
+  if (data && data.length > 0 && rows.length === 0)
+    return <li className="p-3 text-sm text-muted-foreground">{t("common.noMatches")}</li>;
+  return rows.map((v) => (/* the EXISTING <li> row markup, unchanged */));
+})()}
+```
+  Keep the `isError`/empty(`data?.length === 0`) branches as-is. (Prefer a clean inline: compute `rows` before the `return`, but the IIFE keeps it local — implementer may hoist `const rows = …` above the JSX instead, whichever is cleaner and lint-clean.)
+  - **Rename empty-guard:** in the rename `<form onSubmit>`, add a guard before mutate:
+```tsx
+onSubmit={(e) => {
+  e.preventDefault();
+  if (!draftKey.trim()) return;
+  renameVocabulary.mutate({ id: v.id, key: draftKey.trim() }, { onSuccess: () => setEditingId(null) });
+}}
+```
+
+- [ ] **Step 2: `vocabulary-terms.tsx`** — add `const [filter, setFilter] = useState("");`; import `byLabel` from `../lib/sort`. Add a filter `<Input>` above the terms list (the component already has `Input` imported; place it above the `{isLoading ? … : <ul>}` block). In the `<ul>`, replace `{terms?.map((term) => …}` with filtered (`labelText(term.labels, lang).toLowerCase().includes(q)`) + `.sort(byLabel(lang))`; filtered-empty (terms exist) → `common.noMatches` `<li>`. Add `type="url"` + `placeholder={t("labels.uriPlaceholder")}` to the add-term `external_uri` `<Input id="term-uri">`.
+
+- [ ] **Step 3: `term-row.tsx`** — import `ExternalUriLink` from `../components/external-uri-link`. In read mode, wrap the label + URI in a flex-1 column so the URI shows under the label:
+```tsx
+<div className="flex-1">
+  <div>{labelText(term.labels, lang)}</div>
+  {term.external_uri && <ExternalUriLink uri={term.external_uri} />}
+</div>
+```
+(Replace the existing `<span className="flex-1">{labelText(...)}</span>`; keep the Edit + DeleteConfirmDialog.) Add `type="url"` + `placeholder={t("labels.uriPlaceholder")}` to the edit-mode `external_uri` `<Input>`.
+
+- [ ] **Step 4: Tests** (`vocabularies.test.tsx`) — extend (mirror the existing MSW/`tree()` setup; check the term/vocab fixtures for labels to assert order):
+  - vocabularies render **sorted by key** (seed/confirm the fixture has out-of-order keys; assert DOM order).
+  - typing in the vocab **filter** narrows the list (type a substring → only matching vocab shows).
+  - **rename with an empty key** does NOT call the rename endpoint (override the PATCH/PUT handler with a spy; clear the rename input and submit; assert no request).
+  - a **term read row shows its `external_uri`** as a link (seed a term fixture with `external_uri`; assert `getByRole("link", { name: /<uri>/ })`). (If the term fixture lacks a URI, add one — check `materialTerms` in `web/src/test/fixtures.ts`.)
+  Keep existing vocab tests green. Don't weaken.
+
+- [ ] **Step 5: Verify (vitest ONCE):** `cd web && pnpm vitest run src/vocab && pnpm typecheck && pnpm lint`. PASS.
+
+- [ ] **Step 6: Commit**
+```bash
+git add web/src/vocab/vocabulary-list.tsx web/src/vocab/vocabulary-terms.tsx web/src/vocab/term-row.tsx web/src/vocab/vocabularies.test.tsx
+git commit -m "feat(web): vocab list/terms sort+filter, external_uri in rows, rename guard, url input (#50)"

+
+# Task 3: Authorities — filter + sort + create URI + read URI
+
+**Files:** `web/src/authorities/authorities-page.tsx`, `web/src/authorities/authority-row.tsx`, `web/src/authorities/authorities.test.tsx`.
+
+- [ ] **Step 1: `authorities-page.tsx`** — add `const [filter, setFilter] = useState("");` and `const [uri, setUri] = useState("");`; import `byLabel` from `../lib/sort` and `Input`/`Label` (`Input` may need importing — check; `Button` already imported).
+  - **Filter `<Input>`** above the list block (below the tablist):
+```tsx
+<div className="mb-3">
+  <Input aria-label={t("common.filter")} placeholder={t("common.filter")} value={filter} onChange={(e) => setFilter(e.target.value)} />
+</div>
+```
+  - In the loaded `<ul>`, replace `{authorities?.map((a) => …}` with filtered (`labelText(a.labels, lang).toLowerCase().includes(q)`) + `.sort(byLabel(lang))`; filtered-empty (authorities exist) → `common.noMatches` `<li>`.
+  - **Create form gains an `external_uri` field** (after the `<LabelEditor>`):
+```tsx
+<div className="space-y-1">
+  <Label htmlFor="auth-create-uri">{t("labels.externalUri")}</Label>
+  <Input id="auth-create-uri" type="url" placeholder={t("labels.uriPlaceholder")} value={uri} onChange={(e) => setUri(e.target.value)} />
+</div>
+```
+  - In `onCreate`, send the URI and reset it:
+```tsx
+create.mutate(
+  { kind: kind as string, external_uri: uri.trim() || null, labels },
+  { onSuccess: () => { setLabels([]); setUri(""); } },
+);
+```
+
+- [ ] **Step 2: `authority-row.tsx`** — same as term-row: import `ExternalUriLink`; read mode shows label + `ExternalUriLink` (when `authority.external_uri`) in a `flex-1` column; edit `external_uri` `<Input>` gets `type="url"` + `placeholder={t("labels.uriPlaceholder")}`.
+
+- [ ] **Step 3: Tests** (`authorities.test.tsx`) — extend (mirror existing setup; check `personAuthorities` fixture):
+  - list **sorted by label** (assert DOM order; ensure fixture has out-of-order labels or seed it).
+  - **filter** narrows the list.
+  - the **create form has an `external_uri` field** and a created authority **posts the entered URI** (spy the POST body; type a URI; assert `body.external_uri`).
+  - a **read row shows the `external_uri`** link (seed a fixture authority with a URI).
+  Keep existing authorities tests green (tabs, aria-selected, create-without-label alert, 500, redirect).
+
+- [ ] **Step 4: Verify (vitest ONCE):** `cd web && pnpm vitest run src/authorities && pnpm typecheck && pnpm lint`. PASS.
+
+- [ ] **Step 5: Commit**
+```bash
+git add web/src/authorities/authorities-page.tsx web/src/authorities/authority-row.tsx web/src/authorities/authorities.test.tsx
+git commit -m "feat(web): authorities sort+filter, create external_uri, external_uri in rows, url input (#50)"
+```

+
+# Task 4: Fields — filter + within-group sort + group order + count badges + gate
+
+**Files:** `web/src/fields/field-list.tsx`, `web/src/fields/fields.test.tsx`.
+
+- [ ] **Step 1: `field-list.tsx`** — import `byLabel` and `compareStrings` from `../lib/sort` and `Badge` from `@/components/ui/badge`. Add `const [filter, setFilter] = useState("");` (add `useState` to the React import). After the early returns, before grouping:
+  - Filter `data` by label/key: `const q = filter.trim().toLowerCase(); const filtered = (data ?? []).filter((d) => !q || labelText(d.labels, lang).toLowerCase().includes(q) || d.key.toLowerCase().includes(q));`
+  - Build the `groups` Map from `filtered` (not `data`).
+  - **Sort group entries** named A–Z (collator), `t("fields.other")` last:
+```tsx
+const otherLabel = t("fields.other");
+const entries = [...groups.entries()].sort((a, b) => {
+  if (a[0] === otherLabel) return 1;
+  if (b[0] === otherLabel) return -1;
+  return compareStrings(lang, a[0], b[0]);
+});
+```
+  - **Sort each group's defs** by `byLabel(lang)`: when rendering `defs.map`, use `[...defs].sort(byLabel(lang)).map(...)`.
+  - **Count badge** in each group header:
+```tsx
+<div className="flex items-center justify-between border-b bg-muted px-3 py-1 label-caption">
+  <span>{group}</span>
+  <Badge variant="secondary">{defs.length}</Badge>
+</div>
+```
+  - Render a **filter `<Input>`** above the `<ul>` (wrap the return in a fragment/column): a `<div className="border-b p-2"><Input aria-label={t("common.filter")} placeholder={t("common.filter")} value={filter} onChange={(e) => setFilter(e.target.value)} /></div>` then the `<ul>`. If `filtered.length === 0` (data exists), show `<p className="p-3 text-sm text-muted-foreground">{t("common.noMatches")}</p>` instead of the `<ul>`. (Import `Input` from `@/components/ui/input`.)
+  Note: the filter Input must remain visible during the empty-filter state so the user can clear it.
+
+- [ ] **Step 2: Tests** (`fields.test.tsx`) — extend (mirror existing setup; `fieldDefinitions` fixture):
+  - fields render **sorted within their group by label** (assert relative DOM order of two fields in the same group).
+  - a **group header shows a count badge** (assert the count number is present near a group label).
+  - typing in the **filter** narrows the visible fields (and/or shows `common.noMatches` when nothing matches).
+  Keep the existing fields tests green (grouped list, create text field, reveal pickers).
+
+- [ ] **Step 3: FULL GATE (run tests EXACTLY ONCE):**
+```bash
+cd web && pnpm typecheck && pnpm lint && pnpm test && pnpm build && pnpm check:size && pnpm check:colors
+```
+All green. Report test totals, largest chunk (KB gz), check:colors line.
+
+- [ ] **Step 4: Codename + status:**
+```bash
+cd /Users/olsson/Laboratory/biggus-dickus
+git grep -in 'biggus\|dickus' -- web/src; echo "codename-exit=$?"
+git status --short
+```
+
+- [ ] **Step 5: Manual smoke (recommended).** `pnpm dev`: each reference list is alphabetized and has a working filter; term/authority rows show their external_uri as a muted link; field groups show counts; the authority create form has a URI field; renaming a vocab to empty does nothing; URI inputs are `type=url` with a placeholder.
+
+- [ ] **Step 6: Commit**
+```bash
+git add web/src/fields/field-list.tsx web/src/fields/fields.test.tsx
+git commit -m "feat(web): field-list filter, within-group label sort, group order, count badges (#50)"
+```
+
+---
+
+## Self-Review (completed)
+
+**Spec coverage:** sort.ts collator + byLabel/byKey + unit test (T1); ExternalUriLink + i18n (T1); vocab list/terms sort+filter + rename guard + read URI + url input (T2); authorities sort+filter + create URI + read URI + url input (T3); fields filter + within-group sort + group A–Z + count badges (T4); gate (T4). Acceptance criteria 1–5 mapped. ✓
+
+**Placeholder scan:** the list-rewrite steps say "the EXISTING row markup, unchanged" with the files quoted, and tests say "check the fixture / seed a URI" with the fixture files named — concrete, not vague. The IIFE-vs-hoist choice is explicitly the implementer's (both lint-clean). No TODOs. ✓
+
+**Type/consistency:** `byLabel(lang)`/`byKey(lang)`/`compareStrings(lang,a,b)` defined in T1, consumed in T2/T3/T4; `ExternalUriLink({uri})` used in term-row + authority-row; the filter `useState`/predicate pattern is uniform across the four lists; `[...arr].sort(...)` (copy, never mutate cache) everywhere. ✓
+
+## Notes
+- No new dependency; 3 new i18n keys (`common.filter`, `common.noMatches`, `labels.uriPlaceholder`), en+sv.
+- Counts: only field-group counts (client-side). Per-vocab term & per-kind authority counts need backend → follow-up.
+- Always sort a COPY of the react-query data (never mutate the cached array).

+# Reference-Data Scannability + Parity — Design
+
+**Date:** 2026-06-08
+**Status:** Approved (brainstorming) — ready for implementation planning.
+**Issue:** #50 (scoped: scannability + parity; layout/edit-modality unification + API-backed counts are follow-ups).
+
+## Context
+
+The three reference-data screens (vocabularies, authorities, fields) render lists in API
+**creation order** with **no client sort and no filter** — finding "Bronze" in a 200-term vocabulary
+is effectively impossible. Read-mode rows show **only the label**; `external_uri` (the point of
+authority control — distinguishing two "Mercury"s) is visible only in edit mode (`term-row.tsx`,
+`authority-row.tsx`). There are **no counts** anywhere. And there are small parity/validation gaps:
+authority **create** has no `external_uri` field (hardcoded `null`) though edit does; vocab **rename**
+lacks the empty-guard the create form has; URI inputs have no `type="url"`/placeholder.
+
+This milestone fixes the daily-pain "can't find / can't disambiguate" problems + the parity gaps,
+**without** changing layout/edit modality (a separate redesign) and **without** backend changes.
+
+**Facts:** `labelText(labels, lang)` exists (`lib/labels.ts`). No `Intl.Collator` anywhere. List
+shapes: term/authority = `{ id, labels, external_uri?: string|null }` (authority also `kind`);
+vocabulary = `{ id, key }` (no labels); field-definition = `{ key, labels, data_type, group?, required, … }`.
+No count field on any view (so per-vocab term counts + per-kind authority counts need backend →
+deferred; **field-group counts are client-side** and in scope). `Badge`/`Input` exist. Mutations:
+`useCreateAuthority` accepts `external_uri` but the page passes `null`; `useRenameVocabulary` has no
+empty-guard; `useAddTerm`/`useUpdateTerm`/`useUpdateAuthority` already accept `external_uri`.
+
+### Decisions (from brainstorming)
+1. Sort every list by label/key with a locale-aware `Intl.Collator`; add a client-side filter `Input`.
+2. Show `external_uri` (linkified, muted) in term/authority read rows; field-group count `Badge`s.
+3. Close the parity/validation gaps (authority-create URI, rename empty-guard, `type="url"` + placeholder).
+
+## Components
+
+### `web/src/lib/sort.ts` (new)
+- A memoized collator per lang: `Intl.Collator(lang, { sensitivity: "base", numeric: true })` (cache in a `Map<string, Intl.Collator>`).
+- `export function byLabel(lang: string)` → `(a: { labels: LabelView[] }, b) => number` comparing `labelText(a.labels, lang)` vs `labelText(b.labels, lang)` via the collator.
+- `export function byKey(lang: string)` → `(a: { key: string }, b) => number` comparing `a.key` vs `b.key`.
+- (Comparators take the minimal structural type so they work for terms/authorities/fields/vocabs.)
+
+### `web/src/components/external-uri-link.tsx` (new)
+A tiny shared read-mode link: `function ExternalUriLink({ uri }: { uri: string })` →
+`<a href={uri} target="_blank" rel="noopener noreferrer" className="block truncate text-xs text-muted-foreground hover:text-foreground">{uri}</a>`. Used in term-row + authority-row read mode (render only when `external_uri` is truthy).
+
+### i18n (en + sv parity)
+- `common.filter` = "Filter…" / "Filtrera…"
+- `common.noMatches` = "No matches" / "Inga träffar"
+- `labels.uriPlaceholder` = "https://…" (same in both)
+
+### Per-screen changes
+
+**Vocabularies**
+- `vocabulary-list.tsx`: a filter `<Input>` (placeholder `common.filter`) above the list; filter vocabularies by `key` (case-insensitive `includes`) then **sort by `byKey(lang)`**; if filtered-empty but data exists, show muted `common.noMatches`. Add the **rename empty-guard**: `if (!draftKey.trim()) return;` before the rename mutate.
+- `vocabulary-terms.tsx`: a filter `<Input>` above the terms list; filter terms by `labelText` then **sort by `byLabel(lang)`**; filtered-empty → `common.noMatches`. The add-term `external_uri` `<Input>` gets `type="url"` + `placeholder={t("labels.uriPlaceholder")}`.
+- `term-row.tsx`: read mode renders `<ExternalUriLink uri={term.external_uri} />` under the label when present; the edit-mode `external_uri` `<Input>` gets `type="url"` + the placeholder.
+
+**Authorities**
+- `authorities-page.tsx`: a filter `<Input>` above the list; filter by `labelText` then **sort by `byLabel(lang)`**; filtered-empty → `common.noMatches`. The **create form gains an `external_uri` `<Input>`** (`type="url"`, placeholder) mirroring the edit row, stored in a `useState`, sent via `useCreateAuthority` (replace the hardcoded `external_uri: null`).
+- `authority-row.tsx`: read mode renders `<ExternalUriLink uri={authority.external_uri} />` under the label when present; edit `external_uri` `<Input>` gets `type="url"` + placeholder.
+
+**Fields**
+- `field-list.tsx`: a filter `<Input>` above the list; filter by `labelText`/`key`; **sort groups alphabetically with "Other"/ungrouped last, and sort fields within each group by `byLabel(lang)`**; each group header shows a `<Badge variant="secondary">{count}</Badge>` (count of fields in that group, after filtering); filtered-empty → `common.noMatches`.
+
+## Data flow
+Loaded list → client filter (by label/key substring) → collator sort → render. `external_uri` read
+from the existing view field. Field-group counts from the grouped array length. No new queries.
+
+## Error handling / edges
+- Filter is case-insensitive substring on the localized label (or key). Empty filter = show all.
+- Collator memoized per lang; lang from `i18n.language` (sv/en) as elsewhere.
+- `ExternalUriLink` only renders for truthy `external_uri`; `rel="noopener noreferrer"` + `target="_blank"`.
+- `type="url"` gives the browser's basic URL hint (not strict validation — full validation is a follow-up); it must not block submitting an empty optional URI (the field stays optional → send `null`/omit when blank, exactly as today).
+- Sorting must not mutate the query cache array — sort a copy (`[...list].sort(...)`).
+- Field group ordering: a stable rule (named groups A–Z by collator, then the ungrouped "Other" bucket last).
+
+## Testing
+- **`sort.test.ts`** (unit): `byLabel`/`byKey` order case-insensitively + locale-aware (e.g. "ä" sorts sensibly in sv; "bronze" before "Iron").
+- **Vocabularies** (`vocabularies.test.tsx`): vocabularies render sorted by key; typing in the filter narrows the list; rename with an empty key does not fire the mutation.
+- **Authorities** (`authorities.test.tsx`): list sorted by label; filter narrows; the create form has an `external_uri` field and a created authority posts the entered URI; a read row shows the `external_uri` link.
+- **Vocabulary terms / term-row:** terms sorted by label; a term read row shows its `external_uri` link.
+- **Fields** (`fields.test.tsx`): fields sorted within group; a group header shows a count badge; filter narrows. Keep the existing create/reveal-picker assertions green.
+- Gate: `typecheck`/`lint`/`test`/`build`/`check:size`/`check:colors`; en/sv parity (3 new keys); no codename; no new dependency.
+
+## Acceptance criteria
+1. Every reference list is sorted by label (terms/authorities/fields) or key (vocabularies) via a
+   locale-aware `Intl.Collator`, and has a client-side filter `Input` (with a `common.noMatches`
+   empty state).
+2. `external_uri` is shown (linkified, muted, truncated) in term + authority read rows when present.
+3. Field-group headers show a count `Badge`.
+4. Parity/validation gaps closed: authority **create** has an `external_uri` field and sends it; vocab
+   **rename** has an empty-guard; all `external_uri` inputs use `type="url"` + a placeholder.
+5. `typecheck`/`lint`/`test`/`build`/`check:colors` green; `check:size` reported; en/sv parity; no
+   codename; no new dependency; no layout/edit-modality change; no backend change.
+
+## Out of scope → follow-ups
+- The layout + edit-modality **unification** (authorities → two-pane pane-edit; vocab-rename/term/
+  authority → pane-edit; one create location) — a separate redesign.
+- **API-backed counts**: per-vocabulary term counts and per-kind authority-tab counts (need view/count
+  fields or endpoints).
+- Strict URL validation (beyond `type="url"`); linkifying `external_uri` elsewhere (e.g. object detail).
