Foundation & Identity backend for ThoughtSync: - Quart app factory (create_app) with /api/health + SPA history-fallback - async SQLAlchemy 2.0 + asyncpg engine/session (lazy; boots without a DB) - native email+password auth via signed-cookie session (register/login/logout/me + login_required guard); bcrypt password hashing (72-byte safe) - multi-user sharing-ACL spine (rule 47): users, groups, group_members, and a polymorphic shares table + visible_to_user() SQL predicate (owner OR direct share OR group share) that M1's notes will scope through - Alembic async env (adapted from family pattern) + 0001 foundation migration - DB-free unit tests (app/health/auth-guard, password roundtrip, ACL compile) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FRgehjoz7Yv8LkUfADxACm

The M0 identity + sharing-ACL spine. No notes yet (those arrive in M1); the
|

shares table is polymorphic so notes reuse it without a schema retrofit.
