Phase 5: multi-host agents (0.5.0)
- stackpilot-agent: slim token-guarded FastAPI (reuses compose_service) exposing
stack CRUD/lifecycle/logs + system info; same image, different CMD. agent/
Dockerfile + compose + .env.example.
- Central proxy: Agent model, agent_service (httpx ping/proxy + live status:
online/offline/unauthorized + hostname/last_seen), routers/agents.py
(CRUD + ping + proxied stacks/lifecycle/logs/system).
- Frontend: Settings → Remote hosts (add/check/remove, connectivity dot); Stacks
grouped by host; remote stack detail with lifecycle, live logs, compose/.env edit.
Verified end-to-end: agent+main on a shared network — register (good/bad token),
list/create/start/logs/delete remote stacks, offline detection (502).
Remote backup destinations (SFTP/S3) deferred.
