# Open Threads — zlh-grind

This file tracks active but unfinished work.

Keep it short.

---

## Agent (zlh-agent)

### Dev Runtime System

Completed:

- catalog validation implemented
- runtime installs artifact-backed
- install guard implemented
- all installs now fetch from artifact server (no local artifact assumption)

Outstanding:

- runtime install verification improvements
- catalog hash validation
- runtime removal / upgrade handling

---

### Dev Environment

Completed:

- dev user creation
- workspace root `/home/dev/workspace`
- console runs as dev user
- `HOME`, `USER`, `LOGNAME`, `TERM` env vars set correctly

Outstanding:

- PATH normalization
- shell profile consistency
- runtime PATH injection

---

### Code Server Addon

Status: ✅ Installed, running, browser-verified end-to-end

Confirmed:

- pulled from artifact server (tar.gz)
- installed to `/opt/zlh/services/code-server`
- binds to `0.0.0.0:6000`
- lifecycle endpoints: `POST /dev/codeserver/start|stop|restart`
- detection via `/proc/*/cmdline` scan
- full browser IDE loading confirmed at `dev-6070.zerolaghub.dev`

---

### Game Server Supervision

Completed:

- crash recovery with backoff: 30s → 60s → 120s
- backoff resets if uptime ≥ 30s
- transitions to `error` state after repeated failures
- crash observability: time, exit code, signal, uptime, log tail, classification
- classifications: `oom`, `mod_or_plugin_error`, `missing_dependency`, `nonzero_exit`, `unexpected_exit`

---

### Agent Future Work (priority order)

1. Structured logging (slog) for Loki
2. Dev container `provisioningComplete` state in `/status`
3. Graceful shutdown verification (SIGTERM + wait for Minecraft)
4. Process reattachment on agent restart
5. SSH server install in dev container provisioning pipeline (for CF Tunnel SSH)

---

## Dev IDE Access

### Browser IDE ✅ Fully Working (browser-verified) — Zero Install

```
Browser → dev-<vmid>.zerolaghub.dev → Traefik → API → container:6000
```

This is the primary zero-install access method. VS Code in the browser,
no client software required. Browser-verified and production ready.

### Remaining Work

- confirm "Open IDE" button in portal uses hosted URL in production path
- reduce legacy `/__ide/:id` compatibility paths once portal button confirmed
- simplify and harden `devProxy` — remove stale path-based assumptions

### Local Dev Access — SSH via CF Tunnel (Power Users Only)

**Important:** CF Tunnel SSH requires `cloudflared` installed on the
developer's local machine. This is not zero-install and is an optional
feature for power users who want local VS Code or terminal access.

The browser IDE remains the zero-install story for all developers.

See `knowledge-base/network/cf-tunnel-ssh.md` for full detail.

Current state:
- ✅ CF Tunnel created and connected to bastion VM
- ✅ Cloudflare Zero Trust free plan active
- 🟡 Tunnel SSH hostname mapping not yet configured in Zero Trust dashboard
- 🟡 Bastion SSH proxy jump config not yet done
- 🟡 Dev container SSH server not yet verified
- 🟡 Portal SSH config snippet not yet built

## API (zpack-api)

Completed:

- dev provisioning payload
- runtime/version fields
- enable_code_server flag
- `GET /api/servers/:id/status` — server status endpoint
- `POST /api/dev/:id/ide-token` — IDE token generation + hosted URL
- `GET /api/dev/:id/ide` — bootstrap route
- `/__ide/:id/*` — live tunnel proxy (HTTP + WS, target-bound)
- `handleHostedProxy` — host-based routing via `Host` header vmid extraction
- hosted flow browser-verified end-to-end

Outstanding:

- **Billing endpoints** — need to be added back
- simplify and harden host-native `devProxy`
- dev runtime catalog endpoint for portal
- Headscale auth key generation

---

## Portal (zpack-portal)

Completed:

- dev runtime dropdown
- dotnet runtime support
- enable code-server checkbox
- dev file browser support
- ✅ Site copy/wording rewrite — landing, features, FAQ updated for new platform (no Pterodactyl references)

Outstanding:

- confirm "Open IDE" button fully uses hosted URL flow
- SSH config snippet for power users (optional, clearly labeled as requiring cloudflared install)
- **Pricing page** — blocked on tier/pricing decisions
- **About page** — not yet reviewed
- Remove `testdameon` binary from repo root (7MB, should not be in repo)
- Remove `"nonexistent_key"` from pricing page game list

---

## Pre-Launch Checklist

Outstanding before launch:

- **Upload testing** — test file upload flow end-to-end in dev containers
- **Pricing page** — blocked on tier/pricing decisions
- **About page** — copy not yet reviewed
- **Billing endpoints** — add back to API
- **Stress testing** — k6 IDE session load test + Minecraft bot test
  - See `knowledge-base/operations/stress-testing.md`
- **OPNsense audit** — both routers need systematic validation
  - See `knowledge-base/network/opnsense-checklist.md`
- **Dedicated host migration** — evaluate GTHost upgrade (Gold 6152, Detroit)
  - Trial period: $5/day up to 10 days, PBS restore approach
- Remove `testdameon` binary from zpack-portal repo root
- Remove `"nonexistent_key"` from pricing page game list

---

## Platform

Future work:

- CF Tunnel SSH completion — power user feature, requires client cloudflared install
- artifact version promotion
- runtime rollback support
- Cloudflare R2 for large artifact/mod file delivery at scale
