 Execution workspace for **ZeroLagHub (ZLH)**.
 
-This repo is intentionally lightweight and is used for:
-- handovers / "where we left off" notes
-- architecture decisions + rationale
-- config snippets worth preserving
-- TODO lists that don't belong in a code repo
+This repository is intentionally lightweight and is used for:
+- project handovers / "where we left off" notes
+- architecture decisions and rationale
+- system constraints and guardrails
+- scratch investigations that shouldn't live in code repos
 
-## Latest handover (2026-02-07)
+---
 
-- `SCRATCH/2026-02-07_customer-id-schema.md`
-  - 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**.
+## Latest handover (2026-02-08)
 
-- `SCRATCH/2026-02-07_prometheus-grafana.md`
-  - Prometheus HTTP service discovery via API `/sd/exporters`,
-  - Grafana dashboard import gotchas + the "CPU doesn't match top" note,
-  - Next steps to power portal server cards with metrics.
+**System state**
+- API, frontend, and agent are now aligned and operational.
+- Interactive PTY-backed consoles are stable for both dev and game servers.
+- Customer isolation is enforced end-to-end (API → frontend).
+- Agent update system is live, versioned, and hash-verified.
 
-- `SCRATCH/2026-02-07_host-controls-and-delete-failsafe.md`
-  - Decision: keep delete failsafe, add host controls.
+**Key areas completed**
+- Metrics API (server-side Prometheus summaries)
+- 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.
+See:
+- `SESSION_LOG.md` for chronological execution details
+- `OPEN_THREADS.md` for remaining work
+- `ANTI_DRIFT*.md` for guardrails and constraints
