# zlh-grind

Execution workspace for **ZeroLagHub (ZLH)**.

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 (2026-02-08)

**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.

**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

**Primary focus moving forward**
- Final UI polish & stabilization
- Concurrent provisioning validation
- Hardening agent update + rollback paths
- Defining GA readiness criteria
