JWT SECRET LEAK (F-A3-11) — PASS + +- `fmt.Printf("🔓 JWT validation failed: %v (secret: %s)\n", err, h.jwtSecret)` is completely removed +- Replaced with `log.Printf("[WARNING] [server] [auth] jwt_validation_failed error=%q", err)` +- Uses `log.Printf` (not `fmt.Printf`) — output goes to structured log, not raw stdout +- The word "secret" does not appear in any production log output +- No emoji characters in any new log statements +- Full codebase scan: zero matches for `Printf.*jwtSecret` or `Printf.*SigningPrivateKey` in non-test `.go` files + +### 2b. CONFIG DOWNLOAD AUTH (F-A3-7) — PASS + +- Route `GET /downloads/config/:agent_id` now has `authHandler.WebAuthMiddleware()` applied +- Handler returns placeholder template data only (zero UUID, empty tokens, generic config) +- No actual agent tokens, registration tokens, or secrets in response +- Agent_id mismatch check not needed: WebAuthMiddleware means only admins can call this, agents cannot reach it at all (DEV-021) +- Agent codebase grep confirms: agents never call `/downloads/config/` + +### 2c. UPDATE PACKAGE DOWNLOAD AUTH (F-A3-6) — PASS + +- Route `GET /downloads/updates/:package_id` now has `middleware.AuthMiddleware()` applied +- Rate limiter is still present (additive, not replacing) +- Agent codebase grep confirms: agents do NOT call `/downloads/updates/` directly +- The update install flow uses a different mechanism (nonce-validated download within the install handler) +- Endpoint is primarily used by the dashboard or direct admin access + +### 2d. SCHEDULER STATS AUTH (F-A3-10) — PASS + +- Route changed from `middleware.AuthMiddleware()` to `authHandler.WebAuthMiddleware()` +- Handler is an inline function that calls `subsystemScheduler.GetStats()` and `GetQueueStats()` +- No use of `agent_id` from context — purely admin stats +- Agent JWTs with `issuer=redflag-agent` are now rejected by the issuer validation + +### 2e. REQUIREADMIN MIDDLEWARE (F-A3-13) — PASS + +- `require_admin.go`: reads `user_role` from context (set by WebAuthMiddleware) +- WebAuthMiddleware updated: `c.Set("user_role", claims.Role)` added +- Role != "admin" returns 403 with `[WARNING] [server] [auth] non_admin_access_attempt` +- Role == "admin" calls `c.Next()` +- Function is stateless — no side effects, safe to call multiple times +- All 7 security settings routes are uncommented and protected by WebAuthMiddleware + RequireAdmin +- `security_settings.go` compiles cleanly — API mismatches resolved (DEV-020) + +### 2f. JWT ISSUER VALIDATION (F-A3-12) — PASS + +- `GenerateAgentToken`: `Issuer: JWTIssuerAgent` ("redflag-agent") +- `Login` handler: `Issuer: "redflag-web"` +- `AuthMiddleware`: rejects `Issuer != "redflag-agent"` when issuer is present +- `WebAuthMiddleware`: rejects `Issuer != "redflag-web"` when issuer is present +- Absent issuer: allowed with `[WARNING] [server] [auth] agent_token_missing_issuer` or `web_token_missing_issuer` +- Wrong issuer: rejected with 401 immediately +- Grace period TODO exists: `// TODO: remove issuer-absent grace period after 30 days` + +### 2g. DEAD VERIFY ENDPOINT (F-A3-2) — PASS + +- Route: `api.GET("/auth/verify", authHandler.WebAuthMiddleware(), authHandler.VerifyToken)` +- WebAuthMiddleware sets `user_id` from UserClaims +- Handler reads `user_id` via `c.Get("user_id")` +- Valid web JWT → middleware sets user_id → handler returns 200 with valid=true + +### 2h. AGENT UNREGISTER RATE LIMIT (F-A3-9) — PASS + +- Route: `agents.DELETE("/:id", rateLimiter.RateLimit("agent_reports", middleware.KeyByAgentID), agentHandler.UnregisterAgent)` +- Uses same "agent_reports" rate limit as other agent routes (consistent) +- AuthMiddleware and MachineBindingMiddleware still applied via the group-level middleware (additive) + +### 2i. CORS CONFIGURABLE ORIGIN (F-A3-14) — PASS + +- `os.Getenv("REDFLAG_CORS_ORIGIN")` with default `http://localhost:3000` +- Startup log: `[INFO] [server] [cors] cors_origin_set origin=%q` +- `config/.env.bootstrap.example`: `# REDFLAG_CORS_ORIGIN=https://your-dashboard-domain.com` +- `aggregator-server/.env.example`: `# REDFLAG_CORS_ORIGIN=https://your-dashboard-domain.com` +- Added PATCH to allowed methods, added X-Machine-ID, X-Agent-Version, X-Update-Nonce to allowed headers + +--- + +## PART 3: EDGE CASE AUDIT + +### 3a. Issuer Grace Period — Existing Agent Tokens — PASS + +Trace: Pre-A3 agent JWT (no issuer) → AuthMiddleware +1. Token parses: valid signature, not expired → `token.Valid = true` +2. Claims cast to `*AgentClaims` → succeeds, `claims.AgentID` populated +3. `claims.Issuer == ""` → grace period: warning logged, NOT rejected +4. `c.Set("agent_id", claims.AgentID)` → context set correctly +5. `c.Next()` → agent continues to work + +Code matches this trace. Confirmed. + +### 3b. Cross-Type Token — Wrong Issuer Rejection — PASS + +Trace: Web JWT (Issuer="redflag-web") on agent route → AuthMiddleware +1. Token parses: valid signature → `token.Valid = true` +2. Claims cast to `*AgentClaims` → succeeds (registered claims parse fine) +3. `claims.Issuer = "redflag-web"` → not empty, not "redflag-agent" +4. `log.Printf("[WARNING] [server] [auth] wrong_token_issuer...")` → logged +5. `c.JSON(401, ...)` + `c.Abort()` → REJECTED + +Code matches. Confirmed. + +### 3c. RequireAdmin — Non-Admin User — PASS + +Trace: Web JWT with Role="viewer" → WebAuthMiddleware → RequireAdmin +1. WebAuthMiddleware: valid JWT, `c.Set("user_role", "viewer")` +2. RequireAdmin: `role = c.Get("user_role")` → "viewer" +3. `roleStr != "admin"` → true +4. `log.Printf("[WARNING] [server] [auth] non_admin_access_attempt...")` → logged +5. `c.JSON(403, ...)` + `c.Abort()` → BLOCKED + +Code matches. Confirmed by `TestRequireAdminBlocksNonAdminUsers`. + +### 3d. Security Settings Handler — Placeholder Responses — PASS + +- `GetSecurityAuditTrail`: returns `{"audit_entries": [], "pagination": {...}}` — valid JSON, 200 OK +- `GetSecurityOverview`: calls `GetAllSettings()` and wraps in `{"overview": settings}` — valid JSON +- Neither panics nor returns 500 (no unimplemented method calls) +- Code comments document placeholder nature: "Note: GetAuditTrail not yet implemented in service" + +### 3e. CORS — Missing ENV VAR — PASS + +- `os.Getenv("REDFLAG_CORS_ORIGIN")` returns empty string when unset +- Default `http://localhost:3000` used +- No panic, no error — graceful fallback + +--- + +## PART 4: ETHOS COMPLIANCE + +### 4a. Principle 1 — Errors are History — PASS + +- [x] JWT secret removed from WebAuthMiddleware log +- [x] All new log statements use `[TAG] [system] [component]` format +- [x] No emoji in any new log statements (full grep confirms) +- [x] No banned words in new log messages or comments +- [x] CORS startup log uses `[INFO] [server] [cors]` format + +### 4b. Principle 2 — Security is Non-Negotiable — PASS + +- [x] Config download requires WebAuthMiddleware +- [x] Update download requires AuthMiddleware +- [x] Scheduler stats requires WebAuthMiddleware +- [x] Security settings require WebAuthMiddleware + RequireAdmin +- [x] /auth/verify requires WebAuthMiddleware +- [x] No new unauthenticated endpoints introduced + +### 4c. Principle 3 — Assume Failure — PASS + +- [x] CORS missing env var: default used, no panic +- [x] RequireAdmin handles missing user_role: 403 not panic +- [x] Security settings placeholders: return valid JSON, not 500 + +### 4d. Principle 4 — Idempotency — PASS + +- [x] RequireAdmin is stateless (reads context, no mutations) +- [x] Issuer validation does not mutate any state + +### 4e. Principle 5 — No Marketing Fluff — PASS + +- [x] No banned words in new comments +- [x] RequireAdmin comments are technical + +--- + +## PART 5: PRE-INTEGRATION CHECKLIST + +- [x] All errors logged with correct format +- [x] No new unauthenticated endpoints +- [x] Fallback paths: issuer grace period, CORS default +- [x] Idempotency: RequireAdmin stateless +- [x] Security settings handlers log admin actions via service layer (SetSetting records userID) +- [x] Security review: issuer validation only narrows acceptance +- [x] Tests cover: wrong issuer, non-admin role, missing auth, rate limit +- [x] Technical debt tracked: DEV-019 dead code, DEV-020 placeholder responses, DEV-022 grace period +- [x] Documentation complete + +--- + +## ISSUES FOUND DURING VERIFICATION + +None.
