# 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, and reachable through API proxy
|
||
|
||
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
|
||
- hosted browser IDE flow verified with curl end-to-end through Traefik + API proxy
|
||
|
||
---
|
||
|
||
### 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
|
||
|
||

|
||
|
||
## Dev IDE Access
|
||
|
||
### Browser IDE ✅ Working (host-based through Traefik + API)
|
||
|
||
```
|
||
Browser → dev-<vmid>.zerolaghub.dev → Traefik → API → container:6000
|
||
```
|
||
|
||
Verified flow:
|
||
|
||
1. frontend calls `POST /api/dev/:id/ide-token`
|
||
2. API returns `https://dev-<vmid>.zerolaghub.dev/?token=...`
|
||
3. browser opens hosted URL
|
||
4. Traefik wildcard router forwards to API at `http://10.60.0.245:4000`
|
||
5. API validates token, sets `zlh_dev_ide_token`, redirects to clean host URL
|
||
6. subsequent cookie-backed request redirects to `/?folder=/home/dev/workspace`
|
||
7. final response is `200` with code-server HTML
|
||
8. API remains HTTP + WS proxy boundary to the container
|
||
|
||
Curl-verified response chain:
|
||
|
||
- `GET /?token=...` → `302` + `Set-Cookie: zlh_dev_ide_token`
|
||
- `GET /` with cookie → `302` to `/?folder=/home/dev/workspace`
|
||
- `GET /?folder=/home/dev/workspace` → `200` code-server HTML
|
||
|
||
### Remaining Work
|
||
|
||
- verify full browser behavior beyond curl
|
||
- verify WebSocket behavior in-browser under hosted flow
|
||
- reduce legacy `/__ide/:id` compatibility paths once host-based is fully canonical
|
||
- confirm "Open IDE" button in portal uses hosted URL in production path
|
||
|
||
### Wildcard Edge (Traefik)
|
||
|
||
- Traefik on `zlh-zpack-proxy` (10.70.0.242) handles wildcard TLS via DNS challenge
|
||
- wildcard cert `*.zerolaghub.dev` issued via Let's Encrypt + Cloudflare DNS-01
|
||
- Traefik routes `dev-*.zerolaghub.dev` → API at `http://10.60.0.245:4000`
|
||
- `passHostHeader: true` preserves original hostname through to API
|
||
- no Caddy, no `:8081`, no per-container DNS/Traefik side effects from API
|
||
|
||
### Local Dev Access (Headscale/Tailscale — Future)
|
||
|
||
Outstanding:
|
||
|
||
- confirm `zlh-ctl` Headscale server status
|
||
- implement Tailscale addon install in agent
|
||
- API auth key generation
|
||
- portal setup instructions
|
||
|
||
Constraints: `magic_dns: false`, no exit nodes, no DNS takeover
|
||
|

||
|
||
## 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 (validates token, sets cookie, redirects)
|
||
- `/__ide/:id/*` — live tunnel proxy (HTTP + WS, target-bound)
|
||
- dev routing experiment removed (`devRouting.js`, `devDePublisher.js` deleted)
|
||
- host-based URL generation (`DEV_IDE_HOST_SUFFIX`, `DEV_IDE_RETURN_HOSTED_URL`)
|
||
- `handleHostedProxy` — host-based routing via `Host` header vmid extraction
|
||
- token bootstrap → cookie handoff working under hosted flow
|
||
- hosted flow proxies to container successfully
|
||
|
||
Outstanding:
|
||
|
||
- simplify and harden host-native `devProxy` — remove stale path-based assumptions
|
||
- 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
|
||
|
||
Outstanding:
|
||
|
||
- confirm "Open IDE" button fully uses hosted URL flow
|
||
- browser validation against hosted wildcard model
|
||
- Headscale setup instructions
|
||

||
## Platform
|
||
|
||
Future work:
|
||
|
||
- Tailscale dev access
|
||
- artifact version promotion
|
||
- runtime rollback support
