 ### Critical / security
 
 - [CRITICAL] **server/internal/api/router.go** — Unauthenticated build downloads (`/api/v1/builds/{id}/download`, `/artifact/`). Intentional for agent reinstall (UUID is secret). Suggested fix: optional auth toggle or short-lived signed URLs.
-- [CRITICAL] **server/internal/api/websocket.go** — Unauthenticated agent WebSocket (`/ws/agent`); any client can claim any `agent_id`. Suggested fix: bind `agent_id` to fleet secret baked into forged binary (S2 from prior audit).
-- [CRITICAL] **server/internal/api/websocket.go** — Unauthenticated dashboard WebSocket (`/ws/dashboard`); full fleet telemetry without login. Suggested fix: require Basic auth or session cookie on WS upgrade.
+- [CRITICAL] **server/internal/api/websocket.go** — Agent WebSocket (`/ws/agent`) accepts connections without fleet secret when server secret is unset (first-run). With secret configured, bad secret is rejected; agent can still pick any `agent_id`. Suggested fix: bind `agent_id` to fleet secret baked into forged binary (S2 from prior audit).
 - [CRITICAL] **server/internal/api/ai_handler.go** — Unauthenticated AI endpoints (`/agent/decide`, `/report`, `/heartbeat`); SSRF via caller-supplied Ollama URL. Suggested fix: require fleet secret or dashboard auth.
 - [HIGH] **server/internal/api/router.go** — Plaintext passwords in `users.json`; any authed user can POST `/users`. Suggested fix: bcrypt-only storage (partially done), restrict user management to admin role.
 - [HIGH] **server/internal/api/fleet_handler.go** — Remote code execution via authenticated API (`powershell`/`exec`/`upload`). By design — treat dashboard login as root.

 - [LOW] **server/internal/db/agent_meta.go** — `decodeTags` silently drops invalid JSON in `tags` column (corrupt values become empty slice).
 - [LOW] **server/web/e2e/smoke.spec.ts** — E2E login still uses hardcoded `drjones`/`czapiewski`; fails against first-run random `admin` password. Suggested fix: seed `users.json` in E2E fixture or read creds from env.
 - [LOW] **server/web/src/types/index.ts** — Interfaces only; no runtime type guards for API JSON (validation ad hoc in components).

 ## Fixed (this session)
 
+- **server/internal/api/websocket.go** — `checkDashboardWSToken` compared plain password to bcrypt hash; dashboard WS auth failed after user migration. Now uses `checkPassword`.
+- **server/internal/api/** — Added unit/integration tests for remaining handlers: `handlers.go` (agent/build REST), `router.go` (auth middleware, users, rotate-secret, SPA/dropper routes), `websocket.go` (agent/dashboard WS, fleet secret, max agents, log tail), `dropper_handler.go`, `blueprint_handler.go`, `ws_types.go`. New files: `router_test.go`, `dropper_handler_test.go`, `blueprint_handler_test.go`, `websocket_test.go`, `ws_types_test.go`; expanded `handlers_test.go`. `go test ./internal/api/...` — 159 tests PASS.
+- **server/web/src/components/** — Added `components.test.tsx` (57 tests) covering all 22 component TSX modules (NeonCard, HelpTip, downloads, ErrorBoundary, SessionGate, charts, fleet panels/toolbar/list/remote actions, forge hints, visual widgets, layout, ambient/matrix/cursor). Vitest `environmentMatchGlobs` includes `src/components/**`.
+- **server/web/src/pages/AgentsPage.test.tsx** — `AgentRemoteActions` mocked to avoid live `listBuilds` / ECONNREFUSED :3000 in detail-panel tests.
+- **server/web/src/api/client.ts** — `fetchJSON` spread `...options` after merged headers could drop `Content-Type` and `Authorization` when callers pass `options.headers`; headers now merged after rest spread.
+- **server/web/src/api/** — Added `client.test.ts` (19) and `download.test.ts` (6): paths, query params, auth headers, FormData fusion builds, error bodies. Expanded `auth.test.ts` (+1 sessionStorage throw path).
+- **server/web/src/context/** — Added `WebSocketContext.test.tsx` (2), `WebSocketProvider.test.tsx` (8), `ForgeContext.test.tsx` (4): mock WebSocket connect URL/token, message handlers, `_seq` ring buffer, reconnect timer, forge state machine.
 - **server/web/src/pages/BuilderPage.tsx** — Load failure no longer stuck on “Loading forge defaults…” when `form` is null; error message shown instead. Wallet placeholder/short-wallet hint aligned to 90–106 chars. Exported `formatBytes` helper.
 - **server/web/src/pages/SettingsPage.tsx** — Wallet placeholder aligned to 90–106 chars. Exported `deepMerge` helper (config import).
 - **server/web/src/pages/** — Added `BuilderPage.test.tsx` (13) and `SettingsPage.test.tsx` (11, Calibrate UI at `/settings`). Page suite now 4 files / 46 tests.
