+# 2026-03-15 – Dev IDE proxy implementation
+
+## Summary
+
+DNS/Traefik routing experiment for dev IDEs was abandoned and replaced with
+a secure API proxy model. IDE access is now fully implemented in the API
+with a short-lived token system.
+
+---
+
+## What Was Removed from API
+
+Deleted files:
+
+- `src/services/devRouting.js`
+- `src/services/devDePublisher.js`
+
+Removed dev-routing hooks from:
+
+- `src/api/provisionAgent.js`
+- `src/routes/containers.js`
+
+`src/services/proxyClient.js` was intentionally **not deleted** — it is
+still used by the game edge publish path. Removing it would break game routing.
+
+Dev provisioning now only performs: container creation, agent configuration,
+runtime installation, optional `enable_code_server` flag. No DNS or Traefik
+routing is created for dev containers.
+
+---
+
+## What Was Implemented
+
+### Dev IDE Proxy (`src/routes/devProxy.js`)
+
+Mounted in `src/app.js`.
+
+Routes:
+
+```
+GET /api/dev/:id/ide
+GET /api/dev/:id/ide/*
+```
+
+Behavior:
+
+- validates authentication
+- verifies container ownership
+- requires `ctype === "dev"`
+- requires container IP
+- proxies to `http://<container-ip>:6000`
+- rewrites `/api/dev/:id/ide/...` → `/...`
+- WebSocket support via `http-proxy-middleware` (`ws: true`)
+- `server.on("upgrade")` handler wired for WS proxy
+
+Dependency added: `http-proxy-middleware`
+
+---
+
+### IDE Token System (`POST /api/dev/:id/ide-token`)
+
+Problem: opening `/api/dev/:id/ide` in a new tab loses `Authorization: Bearer` header.
+
+Solution: short-lived signed IDE tokens.
+
+Response:
+
+```json
+{
+  "token": "<signed-token>",
+  "url": "/api/dev/6062/ide?token=<signed-token>",
+  "expiresIn": 300
+}
+```
+
+Token details:
+
+- signed by API
+- payload: `sub`, `vmid`, `type: "dev-ide"`
+- default TTL: 300 seconds
+- env overrides: `API_AUTH_IDE_TTL_SECONDS`, `API_AUTH_IDE_SECRET`
+
+Proxy accepts either `Authorization: Bearer` or `?token=<ide-token>`.
+WebSocket upgrades validate the same token.
+
+---
+
+### Server Status Endpoint (`GET /api/servers/:id/status`)
+
+File: `src/routes/serverStatus.js`
+
+Mounted in `src/app.js`.
+
+Behavior:
+
+- requires authentication
+- verifies container ownership
+- loads Redis key `agent:<vmid>`
+- returns cached agent status fields
+
+Fields include: `state`, `runtimeInstalled`, `devProvisioned`, `devReadyAt`,
+`codeServerInstalled`, `codeServerRunning`, `workspaceRoot`, `serverRoot`,
+`lastCrashClassification`.
+
+Source: `src/utils/agentPoller.js` polls agent `/status` and caches to Redis.
+
+---
+
+## Frontend Flow
+
+1. Portal calls `POST /api/dev/:id/ide-token`
+2. API returns `{ url, token, expiresIn }`
+3. Portal opens new tab at returned URL
+4. API validates token and proxies to container
+
+---
+
+## What Was NOT Changed
+
+- game provisioning flow
+- game edge publish path
+- game mod APIs
+- game telemetry polling
+- agent poller logic
+- game file routes
+- console transport
+
+Game infrastructure remains exactly as before.
+
+---
+
+## Next Session — Agent Change Required
+
+code-server currently launches with `--auth password`.
+
+Must be changed to:
+
+```bash
+code-server \
+  --bind-addr 0.0.0.0:6000 \
+  --auth none \
+  --base-path /api/dev/<vmid>/ide \
+  /home/dev/workspace
+```
+
+Reasons:
+
+- removes password prompt (API token is now sole auth)
+- `--base-path` required for correct asset loading through proxy path
+
+This is an agent-side change to the code-server addon launch script.
