-**Execution Workspace for ZeroLagHub (ZLH)**
+Execution workspace for **ZeroLagHub (ZLH)**.
 
-This repository exists to capture **live execution context, architectural decisions, and day-to-day grind notes** while building ZeroLagHub.
+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 is **not** a source-of-truth code repo.
-This repo preserves:
-- rationale
-- decision history
-- migration state
-- unresolved threads
+## Latest handover (2026-02-07)
 
-It exists so long-running work can resume cleanly without re-deriving intent.
+- `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**.
 
----
+- `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.
 
-## What This Repo Is For
+- `SCRATCH/2026-02-07_host-controls-and-delete-failsafe.md`
+  - Decision: keep delete failsafe, add host controls.

-
-## Current Platform Model (Jan 2026)
-
-### Control Plane
-
-- **API v2**  
-  Owns:
-  - auth
-  - ownership
-  - permissions
-  - orchestration
-  - routing to agents
-
-- **ZLH Agent (inside every server/LXC)**  
-  Owns:
-  - service lifecycle
-  - runtime state
-  - console / output
-  - in-container truth
-
-The API does **not** infer server state.
-The agent is authoritative for runtime behavior.
-
----
-
-## Live Console (Implemented)
-
-ZeroLagHub now provides a **true interactive server console**:
-
-- Dev servers expose a live shell (PTY-backed)
-- Game servers expose live Minecraft console access
-- Console sessions survive browser reconnects
-- No SSH, no Proxmox console access required
-- All execution occurs inside the container via the agent
-
-This replaces all prior log-only or exec-based approaches.
-
----
-
-## Portal UX Philosophy (Locked)
-
-### Dashboard
-- Situational awareness only
-- No operational controls
-- System Health indicator (frontend ↔ backend connectivity)
-- Notices timeline (expandable, scrollable)
-- Resource summaries only
-
-### Servers Page
-- Grouped by server type (GAME / DEV)
-- Expandable server cards
-- Collapsed = status
-- Expanded = context
-- Single escalation action: **System View**
-
-### System View
-- Observation-first detail page
-- Runtime output, metadata, health
-- Future controls may live here
-- No AWS-style console metaphors
-
----
-
-## What This Repo Is NOT For
-
-- Final schemas
-- Billing logic
-- Infrastructure secrets
-- Canonical documentation
-
-Those live elsewhere.
-
----
-
-This repo intentionally favors **clarity over completeness**.
+`SCRATCH/` contains one-off notes that may later be promoted into formal docs.
