+# 2026-03-15 – Dev routing + status exposure
+
+## Summary
+
+Work focused on the dev-container path for code-server and the frontend/API state gap.
+
+---
+
+## Completed
+
+### API / routing
+
+- Added dev-only routing hook during provisioning
+- Reused existing Cloudflare + Technitium record creation for dev containers
+- Added Traefik dynamic file creation for dev containers
+- Kept existing game publish flow untouched
+- Remote Traefik writes now use SSH service account model
+- Added `zlh` SSH user path for proxy writes
+
+### Agent / runtime validation
+
+- Confirmed code-server artifact was the correct compiled release artifact
+- Confirmed code-server installs correctly inside dev containers
+- Confirmed code-server process launches successfully
+- Confirmed code-server binds to `0.0.0.0:6000`
+- Confirmed agent remains on `:18888`
+
+### API / frontend status
+
+- Added API endpoint(s) to expose polled agent status back to frontend
+- Frontend host/console status now updates correctly from API state
+- Console availability issue was frontend/API state exposure, not PTY transport
+
+---
+
+## Important confirmations
+
+### Code-server process
+
+Observed process:
+
+```bash
+/opt/zlh/services/code-server/lib/node /opt/zlh/services/code-server \
+  --bind-addr 0.0.0.0:6000 \
+  --auth password \
+  /home/dev/workspace
+```
+
+This confirmed earlier confusion — ss showed the process as `node` because
+code-server runs on Node internally. The process is code-server, not a
+conflicting Node runtime process.
+
+### Proxy/service path
+
+Confirmed working pieces:
+
+- Traefik loads dev dynamic file
+- Traefik router and service are created
+- backend target resolves to container IP on `:6000`
+- API can write remote Traefik config via SSH automation
+- internal/private-network checks from proxy side pass as expected
+
+---
+
+## Current blocker
+
+External browser access to:
+
+```
+https://dev-6062.zerolaghub.dev
+```
+
+is still not complete.
+
+State at end of session:
+
+- Traefik route exists
+- backend service exists
+- code-server runs inside container
+- frontend/API status path is fixed
+- browser still fails externally with connection-closed / blocked-origin behavior
+
+This remains an explicit open thread and should not be treated as solved.
+
+---
+
+## Notes
+
+- Hostname format must remain consistent (`dev-<vmid>`)
+- Game publish flow must remain untouched
+- Dev routing is additive only
+- Proxy SSH must remain service-account based (`zlh`)
