Pre-release audit fixes: - External Administrators can only act on investors already in their own funds (grant_access, create_statement, set_partner_exited, import match), closing a cross-fund account-takeover chain. - Role and is_active changes are gated: no self-escalation, non-approvers cannot mint or alter approver accounts, and the Service Admin is protected. - must_change_password is enforced server-side, not just in the client. - Session cookie is Secure with a 12h max-age and SameSite; CSP and standard security headers on every response; the app refuses to boot on a known or short session secret; uvicorn runs with proxy-headers so login throttling keys on the real client IP behind the platform proxy. - Import preview no longer confirms cross-fund investors; no-store on document downloads. - Adds backend/tests/test_security_hardening.py (15 tests); full suite 76 passing. - SECURITY-AUDIT.md records the swarm audit, findings, and remediation status.
