F-098 — Implementer evidence

Root cause

store_settings.updated_by references identity_users(id), while admin authentication returns IDs from backoffice_users. Saving settings therefore raised a PostgreSQL foreign-key error and surfaced as HTTP 500.

Fix

settings.routes.ts now checks whether the authenticated ID exists in identity_users; it writes the audit ID only when valid, otherwise writes NULL, preserving the FK and allowing backoffice settings saves.

Smoke test

• Authenticated PATCH /api/admin/settings with AI provider, base URL, model, and prompts: HTTP 200.
• Response includes saved AI configuration fields without exposing API key.
• Test rows removed after the smoke test.
• Services restarted successfully on ports 3000/3003/3004/3005.
