- Add MAX_PING_IPS=4096 constant and validate list size in PingRequest before spawning futures, returning 422 on overflow - Add test_ping_too_many_ips_rejected to cover the new cap - Pin httpx<0.28 in requirements-test.txt (0.28 broke TestClient API) - Fix reset_db fixture to set a known admin password regardless of INITIAL_ADMIN_PASSWORD env var (was causing 401 on all auth tests) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
