+## Latest handover (2026-02-08)
-  - Why a newly registered user looked "hashed" (it's Prisma `cuid()`),
-  - Why `ContainerInstance.customerId` got polluted with `u-dev-001`,
-  - The chosen short-term rule: **use `req.user.id` everywhere**.

+**System state**
-  - Prometheus HTTP service discovery via API `/sd/exporters`,
+- API, frontend, and agent are now aligned and operational.
-  - Grafana dashboard import gotchas + the "CPU doesn't match top" note,
+- Interactive PTY-backed consoles are stable for both dev and game servers.
-  - Next steps to power portal server cards with metrics.
+- Customer isolation is enforced end-to-end (API → frontend).
+- Agent update system is live, versioned, and hash-verified.

+- Game console UI (metrics, notes, player presence)
+- Agent auto-update pipeline (manifest + SHA validation)
+- Minecraft player presence via agent `/game/players`
+- Forge startup race condition resolved
+- Prometheus SD schema + auth fixes
 
-## Scratchpad
+**Primary focus moving forward**
+- Final UI polish & stabilization
+- Concurrent provisioning validation
+- Hardening agent update + rollback paths
+- Defining GA readiness criteria
 
-`SCRATCH/` contains one-off notes that may later be promoted into formal docs.
