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.
Address the security-auditor findings the user selected (items 2, 3, 4):
Default admin credentials (P2): remove the fixed `Ten31` default. First
boot now generates a strong random admin password (secrets.token_urlsafe),
records it 0600 at /data/.admin-password, and surfaces it once via a new
"Show Initial Admin Password" StartOS action (CLI `show-admin-password`).
The stored password is cleared when the admin is reset (CLI reset-password)
or self-changes it (change-password endpoint).
Login hardening (P2): add a per-IP in-memory sliding-window rate limiter
(10 failures / 5 min -> 429 + Retry-After) in ratelimit.py; run a dummy
argon2 verify when the user is unknown so timing can't enumerate usernames;
keep a single generic 401 for unknown-user and wrong-password.
Hardening (P3): server process now runs unprivileged -- Dockerfile adds
uid 10001 appuser; start.sh (still root) chowns the mounted /data then
drops via `setpriv` before exec'ing uvicorn. Spreadsheet imports are
size-capped via storage.read_capped (413 past MAX_UPLOAD_SIZE) in the
schedule, capital preview, and batch paths. batch_import no longer returns
raw exception text (generic per-file messages).
Verified in the packed amd64 container: PID1 uvicorn runs as uid 10001,
/data owned 10001 with 0600 secrets; generated admin password retrievable
via CLI and logs in (200); 11th bad login -> 429; admin reset clears the
stored password. Tests: test_auth_hardening.py (4). Full suite 21 passed;
frontend tsc + StartOS bundle clean.

Snapshot commit bringing the uncommitted phase-2 work into version control
together with four new features and the 0.2.22 version bump.
New features:
- Investor capital-over-time chart (value, paid-in, distributions per
quarter), rendered from existing capital-account history.
- Admin Investor View: read-only reconstruction of an investor's portal
(GET /api/users/{id}/investor-view), reusing the investor portal UI.
- Document upload scoped to the selected fund's own investors, with an
explicit upload-target confirmation to prevent mis-attaching.
- GP/mgmt entities gain an Assets tab listing their stakes in the funds
they manage (new entity_stakes table + /api/entities/{id}/stakes).
- Edit-entity form (change type/status/etc.), so GP entities can be
categorized correctly.
Verified: 11/11 backend tests pass; alembic upgrades to head b8c9d0e1f2a3;
frontend tsc + vite build clean; s9pk packs at 0.2.22:0 (x86_64).
Also: ignore .DS_Store and *.s9pk artifacts.
- Dockerfile: multi-stage build (Node frontend + Python backend)
- StartOS manifest, interfaces, backups, version graph
- start.sh: auto-generates session secret, creates first approver on boot
- Backend serves built frontend as SPA in production
- Single data volume for SQLite DB, platform backups cover it
