+# AAMOS Auth Audit Report
+**Date:** 2026-07-14  
+**Auditor:** Bernt (AI Agent)  
+**Scope:** All AAMOS authentication systems
+
+---
+
+## Executive Summary
+
+| System | Status | Auth Method | JWT Type | SSO | Production Ready |
+|--------|--------|-------------|----------|-----|------------------|
+| **AAMOS Admin v2** | ✅ Running | Cookie + Bearer | RS256 | Google One Tap | ⚠️ Partial |
+| **quiXzoom API** | ✅ Running | Bearer | RS256 | ❌ No | ⚠️ Partial |
+| **aamos-ledger** | ✅ Running | Bearer | RS256 | ❌ No | ⚠️ Partial |
+| **ouroboros-identity** | ❌ STOPPED | — | RS256 | ❌ No | ❌ No |
+| **BOC** | 🚧 Dev | Bearer | HS256 | ❌ No | ❌ No |
+
+**Critical Finding:** ouroboros-identity (the designated identity service) is **STOPPED**. All auth currently flows through `aamos-admin-v2` API gateway.
+
+---
+
+## 1. AAMOS Admin v2 (api/auth-routes.js) — PRIMARY AUTH SYSTEM
+
+**Port:** 443 (via API Gateway)  
+**File:** `/opt/amos/api/auth-routes.js`
+
+### What Works
+- ✅ **Local admin login** — hardcoded users (erik@aamos.systems, dev@hypbit.com)
+- ✅ **DB user login** — scrypt password verification against prexo_users / ouroboros_users
+- ✅ **Google One Tap OAuth** — credential verification via Google tokeninfo
+- ✅ **RS256 JWT signing** — uses `/opt/amos/data/keys/jwt-private.pem`
+- ✅ **Refresh tokens** — 7-day refresh with denylist
+- ✅ **Password reset** — SMS (46elks) + email (Resend) with 6-digit codes
+- ✅ **Cookie-based SSO** — `aamos_token` + `aamos_refresh` cookies
+- ✅ **Role-based access** — group-ceo, group-cto, group-cfo, group-admin, admin, super_admin
+
+### Auth Flow
+```
+User → POST /api/auth/login
+  ├── Local admin bypass (hardcoded passwords)
+  ├── DB check (scrypt hash in PostgreSQL)
+  └── Google One Tap (credential from frontend)
+       ↓
+  RS256 JWT signed with jwt-private.pem
+       ↓
+  Cookie: aamos_token (24h) + aamos_refresh (7d)
+       ↓
+  All subsequent requests: Bearer token OR cookie
+```
+
+### JWT Claims Structure
+```json
+{
+  "sub": "user-uuid",
+  "email": "user@example.com",
+  "name": "User Name",
+  "org": "org-uuid",
+  "roles": ["admin", "group-admin"],
+  "iss": "amos.aamos.systems",
+  "exp": 1721030400,
+  "iat": 1720944000
+}
+```
+
+### What's Broken / Risky
+- ❌ **Identity service STOPPED** — ouroboros-identity (port 3207) is inactive
+- ❌ **Hardcoded admin passwords** — LOCAL_ADMINS in plaintext
+- ❌ **No MFA** — SMS/email reset is single-factor
+- ❌ **No rate limiting** — brute force possible on /login
+- ❌ **HS256 fallback** — if RS256 keys missing, falls back to HS256 with fallback secret
+- ❌ **No token introspection** — /me just decodes, doesn't check revocation
+
+---
+
+## 2. quiXzoom Auth (/api/qz/auth)
+
+**Port:** 443 (via quixzoom-api.service)  
+**File:** `/opt/amos/data/quixzoom-api/routes/auth.mjs`
+
+### What Works
+- ✅ **Registration** — email + password + role (zoomer/orderer)
+- ✅ **Login** — bcrypt password verification
+- ✅ **Email verification** — SES welcome email with verify link
+- ✅ **RS256 JWT** — same keypair as AAMOS
+- ✅ **Token refresh** — /refresh endpoint
+
+### Auth Flow
+```
+Zoomer → POST /api/qz/auth/register
+  └── bcrypt hash → PostgreSQL quixzoom.users
+       ↓
+  POST /api/qz/auth/login
+       ↓
+  RS256 JWT (issuer: identity.quixzoom.com)
+```
+
+### What's Broken / Risky
+- ❌ **Separate user DB** — quixzoom.users ≠ prexo_users ≠ ouroboros_users
+- ❌ **No SSO with AAMOS** — can't use AAMOS login for quiXzoom
+- ❌ **No Google OAuth** — only email/password
+- ❌ **No password reset** — missing /reset-request endpoint
+
+---
+
+## 3. aamos-ledger Auth
+
+**Port:** 3250  
+**File:** `/opt/amos/services/aamos-ledger/auth.mjs`
+
+### What Works
+- ✅ **RS256 verification** — reads jwt-public.pem
+- ✅ **Role checking** — admin, accountant, viewer
+- ✅ **AAMOS token compatible** — accepts tokens from auth-routes.js
+
+### What's Broken / Risky
+- ❌ **No own login** — relies on external auth service
+- ❌ **No user DB** — doesn't store users, just validates tokens
+
+---
+
+## 4. ouroboros-identity (STOPPED)
+
+**Port:** 3207 (INACTIVE)  
+**File:** `/home/bernt/rust/ouroboros-identity/src/main.rs`
+
+### What It Was Supposed To Do
+- RS256 JWT signing/verification
+- User management (prexo_users table)
+- Org/tenant isolation
+- Role-based access
+
+### Why It's Stopped
+```bash
+sudo systemctl status ouroboros-identity.service
+# Active: inactive (dead)
+```
+
+**Likely cause:** Rust binary crash or deployment issue. Needs investigation.
+
+---
+
+## 5. BOC Auth (In Development)
+
+**Port:** 9092 (planned)  
+**Files:** `boc/backend/auth/auth.go`, `boc/backend/handlers/auth.go`
+
+### Current State
+- ✅ **AAMOS-standard JWT claims** — sub, email, org_id, roles, scopes
+- ✅ **HS256 signing** — (should be RS256 for production)
+- ✅ **Middleware** — Bearer token validation
+- ✅ **Role middleware** — RequireRole("admin", "viewer")
+- ✅ **18 tests passing** — login, validation, middleware, roles
+
+### What's Missing
+- ❌ **RS256 support** — only HS256, no keypair
+- ❌ **No Google OAuth** — no SSO integration
+- ❌ **No password reset** — missing /reset-request
+- ❌ **No refresh tokens** — single 24h token
+- ❌ **No cookie support** — only Bearer header
+- ❌ **Separate user DB** — boc_users table, not synced with AAMOS
+
+---
+
+## 6. Google OAuth Integration
+
+**Status:** ✅ Working in AAMOS Admin v2
+
+### Flow
+```
+Frontend (Google One Tap)
+  └── credential (Google ID token)
+       ↓
+  POST /api/auth/google
+       ↓
+  Verify with https://oauth2.googleapis.com/tokeninfo
+       ↓
+  Issue AAMOS RS256 JWT
+```
+
+### Client ID
+```
+168062155822-c6qvngkn5193ckipssoubgrvb0v4tn9r.apps.googleusercontent.com
+```
+
+### What's Missing
+- ❌ **Not in quiXzoom** — Zoomers can't use Google login
+- ❌ **Not in BOC** — no Google OAuth integration
+- ❌ **No domain restriction** — any Google account can login
+
+---

+
+## Action Items (Priority Order)
+
+### P0 — Critical (Do Today)
+1. **Restart ouroboros-identity** — investigate why it's stopped
+2. **Remove hardcoded passwords** — move to env vars or DB
+3. **Enable rate limiting** — on /login, /reset-request
+
+### P1 — High (This Week)
+4. **BOC RS256 support** — use same keypair as AAMOS
+5. **Unified user DB** — sync boc_users with prexo_users
+6. **Google OAuth in quiXzoom** — reuse AAMOS Google integration
+7. **Token introspection endpoint** — /api/auth/validate for all services
+
+### P2 — Medium (Next Sprint)
+8. **MFA support** — TOTP or SMS for admin accounts
+9. **Password policies** — min length, complexity, rotation
+10. **Session management** — view active sessions, revoke
+11. **Audit logging** — all auth events to SOC2 evidence
+
+### P3 — Low (Backlog)
+12. **SCIM provisioning** — auto-sync with Google Workspace
+13. **SAML support** — enterprise SSO
+14. **Federated login** — BankID (Sweden), Vipps (Norway)

+### AAMOS Auth Endpoints (Manual Check)
+```bash
+# Health check
+curl https://amos.aamos.systems/health
+# → {"ok":true}
+
+# Login (local admin)
+curl -X POST https://amos.aamos.systems/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"erik@aamos.systems","password":"Erik1987"}'
+# → {"token":"eyJ...","refresh_token":"eyJ..."}
+
+# Me (with token)
+curl https://amos.aamos.systems/api/auth/me \
+  -H "Authorization: Bearer <token>"
+# → {"user":{"sub":"...","email":"...","roles":["admin"]}}
+```
+
+---
+
+## Conclusion
+
+**Current State:** AAMOS has a working auth system in `aamos-admin-v2` with RS256 JWT, Google OAuth, and password reset. However, it's a monolithic auth implementation rather than a unified identity service.
+
+**Risk:** ouroboros-identity (the designated identity hub) is stopped. If aamos-admin-v2 fails, all auth stops.
+
+**Recommendation:** 
+1. Fix and restart ouroboros-identity
+2. Migrate all services to use it as the single auth source
+3. BOC should use RS256 + connect to the identity hub, not HS256 with local users
+
+**Auth Maturity: 5/10** — Functional but fragile, not unified.

+# Linus Torvalds Final Evaluation — BOC v1.1
+
+## Score: 6/10 (UP from 3/10)
+
+---
+
+## ✅ PASS — What's Fixed
+
+### 1. Dead Code ELIMINATED
+- ❌ rust-service/ (deleted)
+- ❌ c-runtime/ (deleted)  
+- ❌ events/kafka.go (deleted)
+- Binary: 15.5MB → 12MB
+
+### 2. Security Hardened
+- JWT_SECRET now required (panics if missing)
+- WebSocket rejects unauthenticated connections (safe default)
+- Bearer token format enforced (no more `***` fallback)
+
+### 3. Tests EXIST (14 packages tested)
+
+| Package | Coverage | Tests |
+|---------|----------|-------|
+| config | 100% | 3 |
+| automation | 33% | 8 |
+| handlers | 2.2% | 12 |
+| ledger | 58.1% | 2 |
+| middleware | 59.5% | 5 |
+| pdf | 34.5% | 4 |
+| store | 76.7% | 6 |
+| **main** | **n/a** | **2** |
+
+**Total: 42 tests, all passing**
+
+### 4. Generic Patterns
+- `Store[T]` — reusable CRUD for any struct
+- `GenerateDocument()` — one PDF function for invoices/quotes
+- `LedgerClient.Get()` — one method replaces 6 copies
+
+### 5. Build Clean
+- `go vet` passes
+- `go build` succeeds
+- No unreachable code
+
+---
+
+## ❌ FAIL — What Linus Still Hates
+
+### 1. handlers package: 2.2% coverage
+You have 20 handler files. You tested 1 (CRM). The other 19 are completely untested:
+- auth.go — login with bcrypt, JWT generation
+- finance.go — invoices, payments, payroll
+- quotes.go — quote → order conversion
+- sales.go — deals, subscriptions
+- hr.go — employees, time tracking
+- inventory.go — stock adjustments
+- projects.go — project management
+- support.go — tickets
+- marketing.go — campaigns
+- legal.go — contracts
+
+**Linus:** "You tested the CRM handler. Great. Now test the one that processes payroll and moves actual money."
+
+### 2. ZERO coverage packages (still)
+
+| Package | Why It Matters |
+|---------|---------------|
+| cache | Redis failures = site down |
+| db | Migrations modify schema |
+| email | Sends real customer emails |
+| models | Core data structures |
+| websocket | 170 lines of dead code |
+
+### 3. No integration tests
+You deleted the broken ones. Didn't replace them. No test verifies the full stack.
+
+### 4. Frontend unchanged
+Still 12 HTML files. SPA proposal is just a markdown file.
+
+### 5. Financial flows untested
+- `ConvertToOrder` — creates invoice from quote
+- `ProcessPayroll` — pays employees
+- `MatchTransaction` — reconciles bank transactions
+
+**These move money. Zero tests.**
+
+---
+
+## ⚠️ MEDIOCRE — Acceptable But Not Good
+
+### 6. Automation 33% coverage
+Better than 0%, but the workflow execution engine (the part that actually runs user-defined actions) is barely tested.
+
+### 7. Error handling inconsistent
+Some handlers return 500 for DB errors. Some log. Some don't. No standard pattern.
+
+---
+
+## What Linus Wants For 8/10
+
+1. **Test the 5 most critical handlers**: auth, finance, quotes, sales, payroll
+2. **Delete websocket package** or implement it
+3. **One integration test**: start server, hit 3 endpoints, verify responses
+4. **Test `ConvertToOrder`** — this is your core business logic
+
+## What Linus Wants For 9/10
+
+5. **80%+ coverage on handlers**
+6. **Tests for cache/redis error paths**
+7. **Frontend SPA actually built**
+
+## What Linus Wants For 10/10
+
+8. **Property-based tests** for financial calculations
+9. **Chaos tests** (kill DB, verify graceful degradation)
+10. **No TODOs in production code**
+
+---
+
+## The Truth
+
+> "You went from 'embarrassing' to 'acceptable prototype.' The code is cleaner, the dead weight is gone, and you have a testing foundation. But you're still not production-ready. You have 42 tests for ~8000 lines of code. That's 1 test per 190 lines. Linux has 1 test per 10 lines. I'm not saying you need Linux-level coverage. I'm saying you need to test the parts that matter — and right now, the parts that matter (money, auth, data integrity) are untested."
+
+— Linus
+
+---
+
+## Recommendation
+
+**Ship to staging, NOT production.**
+
+Run this checklist first:
+- [ ] Test auth handler (login, JWT validation)
+- [ ] Test finance handler (invoice creation, payment recording)
+- [ ] Test quote→order conversion
+- [ ] Add integration test (full stack)
+- [ ] Load test with 100 concurrent users
+- [ ] Security audit (SQL injection, XSS, CSRF)
+- [ ] Frontend SPA migration complete
+
+**Then** deploy.
