Owner

Goal

Add a useIsPremium() hook reading the existing useLicense state. Trivial layer — exists for clarity at call sites.

Contract reference

docs/api-contract-prices.md §7.2 — edition is already read by useLicense hook (cf. src/hooks/useLicense.ts).

Fichiers concernés

src/hooks/useIsPremium.ts (new, ~20 lines)
src/hooks/useIsPremium.test.ts (new, ~30 lines)

Depends on

#154

Scope

Create src/hooks/useIsPremium.ts:

import { useLicense } from "./useLicense";
/** Returns true if the active license is premium. ERGONOMIC ONLY — server enforces independently (cf. ADR 0011 §UX). */
export function useIsPremium(): boolean {
  const { state } = useLicense();
  return state.edition === "premium";
}

Vitest test mocking useLicense via vi.mock:
- edition === "premium" → returns true
- edition === "base" → returns false
- edition === "free" → returns false
Add a 1-line entry to CLAUDE.md hooks listing (« 12 hooks custom » → 13)

Critères d'acceptation

3 vitest tests green
Hook is consumed in PriceFetchControl (issue #158)
CLAUDE.md count is updated

Décisions prises ce soir

Garder un hook séparé (vs inline useLicense().edition === 'premium') pour la lisibilité aux call sites + pour faciliter le mock dans les tests UI.
L'existence des 3 valeurs Edition (free | base | premium) reste inchangée.
