 | Area | Notes |
 |------|-------|
-| **`tunnel_stream`** | Server-side TCP reverse relay documented as future (`README.md`). |
-| **Path Tracer sessions** | `TraceSession` in handler RAM; restart loses state; no DB persistence or startup sweep. |
 | **Non-Windows Path Tracer parity** | `pathtracer_stub.go` errors on `wg_setup`; chains are Windows-agent focused. |
-| **NAT / symmetric UDP** | UPnP + DB IP fallback; no STUN/TURN or post-config connectivity probe. |
+| **NAT / symmetric UDP** | UPnP + DB IP fallback only; no post-config connectivity probe or TURN relay (`architecture_deferred_test.go`). |
 | **Fixed WireGuard port 51820** | Same UDP port all hops; multi-agent behind one NAT may conflict. |
-| **Agent display name vs hostname** | WS `UpsertAgent` preserves operator rename when `name != hostname`; reconnect with hostname only keeps DB label. |
 | **WireGuard auto-download (Windows)** | `ensureWGExe()` on first Path Tracer use; heavy, may need admin; pre-install recommended. |
-| **Monolithic WebSocket context** | All `useWebSocket()` consumers re-render on any WS change; split contexts/selectors deferred. |
-| **`CruciblePage` size (~2k lines)** | Terminal + fleet + tabs in one component; section split/memo deferred. |
-| **WS `init` ships full fleet** | Dashboard connect still loads all agents in one JSON blob; pagination is REST-only (`?limit=&offset=`). |
-| **SQLite single-writer ceiling** | `SetMaxOpenConns(1)` + WAL; sustained 1000+ agents with per-tick DB writes may SQLITE_BUSY; consider Postgres or write batching at 1000+. |
+| **Monolithic WebSocket context** | Single `useWebSocket()` re-renders all consumers; split contexts deferred (`architectureDeferred.test.ts`). |
+| **`CruciblePage` size (~2k lines)** | Terminal + fleet + tabs in one component; section split deferred (`architectureDeferred.test.ts`). |
+| **SQLite → Postgres at 1000+** | `SetMaxOpenConns(1)` + WAL; sustained per-tick writes may SQLITE_BUSY (`architecture_deferred_test.go`). |
 | **In-memory WS agent state** | Hub maps (`agentCapabilities`, `agentLogs`, DNS cache) grow O(agents); no eviction on disconnect beyond log trim. |
 | **Fleet topology 3D cap** | `FleetTopologyMap` renders at most 200 nodes; larger fleets need subnet-grouped view or server-side aggregation. |
 | **Crucible roster pagination** | Roster paginates 80 cards/page; bulk select-all still operates on filtered set in memory. |
 | **No CI HTTP forge** | `e2e-validate.ps1 -ForgeAgent` manual; live compile needs `LIVE_FORGE=1` + `-tags liveforge`. |
 | **Non-Windows forge host** | PE disguise / osslsigncode signing platform-limited by design. |
 | **Mac PathForge runtime** | `.command` curl `/api/download/agent-mac`; needs reachable `server_url` + binary on server. |
-| **Terminal virtualization** | 400-line DOM cap only; full virtual scrollback deferred. |
 | **Vite chunk weight** | `three` + vendor warnings; FleetTopologyMap lazy but heavy first open. |
