internal/hub: the agent's first daemon — a periodic read-only host-report POSTed to
the hub (the heartbeat; no separate ping).
- HostReport wire contract (shared field-for-field with the hub ingest): host
metrics, guests (vmid + spec), cloudflared status; storage/backups/restore-tests/
pbs/audit collections DEFINED but emitted empty (slices 5/6 fill).
- Collector over a read-only proxmoxReader (adapted to the real proxmox surface;
no proxmox changes) + a CloudflaredProber. Partial-failure: NodeStatus fail = hard
(skip POST); per-guest GuestConfig fail = status "unknown", still report.
- Client: Bearer-auth POST, standard TLS (system roots / optional ca_file), typed
TransportError/HTTPError, token never in errors.
- Loop: immediate first report, adopt hub poll_interval (clamp [60,3600]), resilient
to collect/report errors, clean ctx-cancel shutdown.
- ControlEnvelope: only poll_interval_seconds acted on; blocked/desired_generation/
has_signed_ops parsed-but-ignored (slice 4).
- config: HubConfig + FELHOM_AGENT_HUB_* overlay + mode-aware HubConfig.Validate +
WithDefaults + hub-key redaction; example config updated.
- main: no-selftest mode is now the daemon; added --selftest=hub. Version -> 0.3.0.
Tests: report serialization, client (incl. token-redaction), collector partial-
failure, loop continuation+interval adoption, config. internal/proxmox + internal/
authz untouched.
