- Add auth failure logging (login, API key, JWT) with IP/email/prefix
- Move OAuth JWT from URL params to short-lived cookies to prevent
token leakage via browser history, server logs, and Referer headers
- Pin Swagger UI to v5.18.2 with SRI integrity hashes
- Upgrade Go toolchain to 1.25.8 (fixes 5 called stdlib vulns)
- Fix unchecked error in host agent credential refresh
- Add .gstack to .gitignore for security report artifacts
- Internal ECDSA P-256 CA (WRENN_CA_CERT/WRENN_CA_KEY env vars); when absent
the system falls back to plain HTTP so dev mode works without certificates
- Host leaf cert (7-day TTL, IP SAN) issued at registration and renewed on
every JWT refresh; fingerprint + expiry stored in DB (cert_expires_at column
replaces the removed mtls_enabled flag)
- CP ephemeral client cert (24-hour TTL) via CPCertStore with atomic hot-swap;
background goroutine renews it every 12 hours without restarting the server
- Host agent uses tls.Listen + httpServer.Serve so GetCertificate callback is
respected (ListenAndServeTLS always reads cert from disk)
- Sandbox reverse proxy now uses pool.Transport() so it shares the same TLS
config as the Connect RPC clients instead of http.DefaultTransport
- Credentials file renamed host-credentials.json with cert_pem/key_pem/
ca_cert_pem fields; duplicate register/refresh response structs collapsed
to authResponse
- Frontend: BYOC hosts page (/dashboard/byoc) with register/delete flows,
shimmer loading, pulsing online status, animated token reveal checkmark
- Frontend: Admin section (/admin/hosts) with platform + BYOC tabs, stat
pills, skeleton loading, slide-in animations for new rows
- Frontend: AdminSidebar component with accent top bar and admin pill badge
- Frontend: BYOC nav item shown only when team.is_byoc is true (derived
from teams store, not JWT); disabled for members
- Frontend: Admin shield button in Sidebar, visible only to platform admins
- Backend: is_admin in JWT claims + requireAdmin middleware (DB-validated)
- Backend: is_byoc added to teamResponse so frontend derives visibility
from fresh team data rather than stale JWT fields
- Backend: SetBYOC admin endpoint (PUT /v1/admin/teams/{id}/byoc)
- Backend: Admin hosts list enriches BYOC entries with team_name
- Host agent: load .env file via godotenv on startup
Replaces the hardcoded CP_HOST_AGENT_ADDR single-agent setup with a
DB-driven registration system supporting multiple host agents (BYOC).
Key changes:
- Host agents register via one-time token, receive a 7-day JWT + 60-day
refresh token; heartbeat loop auto-refreshes on 401/403 and pauses all
sandboxes if refresh fails
- HostClientPool: lazy Connect RPC client cache keyed by host ID, replacing
the single static agent client throughout the API and service layers
- RoundRobinScheduler: picks an online host for each new sandbox via
ListActiveHosts; extensible for future scheduling strategies
- HostMonitor (replaces Reconciler): passive heartbeat staleness check marks
hosts unreachable and sandboxes missing after 90s; active reconciliation
per online host restores missing-but-alive sandboxes and stops orphans
- Graceful host delete: returns 409 with affected sandbox list without
?force=true; force-delete destroys sandboxes then evicts pool client
- Snapshot delete broadcasts to all online hosts (templates have no host_id)
- sandbox.Manager.PauseAll: pauses all running VMs on CP connectivity loss
- New migration: host_refresh_tokens table with token rotation (issue-then-
revoke ordering to prevent lockout on mid-rotation crash)
- New sandbox status 'missing' (reversible, unlike 'stopped') and host
status 'unreachable'; both reflected in OpenAPI spec
- Fix: refresh token auth failure now returns 401 (was 400 via generic
'invalid' substring match in serviceErrToHTTP)
