- COOKIE_SECURE env now accepts: 'true' (secure), 'false' (memory-only), 'single_user' (no cookie) - config.parse_cookie_mode() returns (COOKIE_SECURE, SINGLE_USER) tuple for routing - single_user_owner() returns oldest Owner for test/local deployments - session cookie respects mode: Max-Age only in secure mode, dropped for memory-only - base.html renders ephemeral-session and single-user banners per mode - Tests: comprehensive coverage for all three modes with monkeypatch configs - CLAUDE.md + README docs updated Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
