Add Légifrance API integration for live legal text injection
Implements a two-layer approach to ensure legal texts are accurate and current: Option A — runtime injection (legifrance_client.py): - LegifranceClient: OAuth2 via PISTE (oauth.piste.gouv.fr), fetches consolidated article text via api.piste.gouv.fr/dila/legifrance/lf-engine-app - Redis cache with 24h TTL (in-memory fallback if no Redis) - build_filter_prompt() injects live texts into the prompt with explicit priority over static descriptions — model uses official Légifrance text, not training memory - Graceful fallback to static prompt if API is unavailable — filtering never blocks Option B — weekly sync script (scripts/check_legal_refs.py): - Reads legal_refs.yaml (11 tracked articles, priority critical/high/medium) - Fetches current text from Légifrance, diffs against stored baseline - --init: resolves LEGIARTI IDs on first run - --check: report only; --update: saves new texts to YAML - Exit code 2 when changes detected (CI/n8n-compatible) Supporting changes: - legal_refs.yaml: tracked articles with code LEGITEXT IDs, priorities, rationale - requirements.txt: add pyyaml>=6.0.2 and requests>=2.32.0 - .env.example: document PISTE_CLIENT_ID, PISTE_CLIENT_SECRET, LEGIFRANCE_CACHE_TTL - transparence.tsx: document the Légifrance injection for public transparency - Fixed portal URL: piste.gouv.fr (not piste.api.gouv.fr — verified June 2026) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
