 ## Closed Threads
 
-- ✅ Interactive console (PTY-backed, bidirectional)
-- ✅ WebSocket stability issues
-- ✅ Dev server CLI access
-- ✅ Game server console streaming
+- ✅ Interactive PTY-backed console (dev + game)
+- ✅ WebSocket stability and PTY ownership
+- ✅ Customer isolation (API + frontend)
+- ✅ Agent update system (versioned, hash-verified)
+- ✅ Minecraft player presence (agent-sourced)
+- ✅ Forge startup race condition
+- ✅ Prometheus SD schema alignment

 ## Still Open
 
-### Console UX Polish
-- Frontend presentation refinement
-- xterm.js-style terminal UI
-- Responsive layout optimization
+### Console UI (Final Polish)
+- Reduce remaining visual noise in game console
+- Confirm final placement/behavior of player list (inline vs overlay)
+- Lock icon sizing + metric density
+- Final accessibility contrast pass
 
-### Console Permissions & Security
-- RBAC for console access
-- Audit logging of console commands
-- Session timeout policies
+### Metrics & Observability
+- Decide on caching strategy for metrics API (Redis vs in-process)
+- Determine long-term retention strategy (Prometheus vs downsampling)
+- Admin-only Grafana dashboards (internal)
 
-### Console Features (Optional)
-- PTY window size propagation (resize handling)
-- Command history
-- Multi-viewer support
+### Provisioning & Scale
+- Validate concurrent provisioning (multi-user, parallel creates)
+- Stress-test agent update under load
+- Define safe limits for agent restart frequency
+
+### Agent Hardening
+- Rollback behavior if new agent fails health checks
+- Optional manifest signing (GPG / minisign)
+- Upgrade window coordination (future)
+
+### Game-Specific Enhancements (Deferred)
+- Mods/runtime badges (Paper / Fabric / Forge)
+- World/map visualization (Minecraft-specific, future phase)
+- Player detail views (separate surface, not console)

-## High Priority
+## Explicit Non-Goals (for now)
 
-### Server Detail / System View
-- Define System View layout
-- Decide runtime vs metadata sections
-- Integrate console as primary action
-
----
-
-### Resource Schema
-- Finalize Resource / Server model
-- Define capability flags
-- Map agent-reported state → UI state
-
----
-
-## Medium Priority
-
-### Notices System
-- Wire notices to real events
-- Define severity levels
-- Persist "since last login" state
-
----
-
-### System Health Logic
-- Replace mocked connectivity check
-- Define degraded vs critical thresholds
-- Decide when yellow state is shown
-
----
-
-## Deferred (Intentional)
-
-### Billing
-- Plan structure exists
-- UX hooks reserved
-- No implementation until platform stabilizes
-
-### Bulk Operations
-- Explicitly removed
-- Will not return unless a future use case demands it

+- In-console player management actions
+- Live chat overlays
+- Grafana iframe embedding for customers
+- Per-player stats in the main console
