DR recipe slice (agent half), grounded in SPIKE-dr-recipe-2026-06-16. Additive
`dr_recipe` host-report section = the non-secret reconstruction scaffolding the
operator must rebuild before PBS bytes can land. Built by pure
BuildDRRecipeHostHalf from facts the report already collects (no new reads):
guests[] sizing, drives[] (user-data by durable_id/role/mount/intent),
pve_storage[] (storage.cfg), pbs coordinates.
BOUNDARY (Phase-1 lesson): every field is an identifier/intent/size/coordinate —
never a key/password/token/hash/ENC:. PBS key stays in escrow; restic password
stays in escrow; the recipe names only the coordinates the restore targets.
Tests: BuildDRRecipeHostHalf selection, NoPBS, NoSecrets (boundary mirror),
dr_recipe key-set in the cross-repo golden contract test. recipe_version=1,
ignore-unknown on read.

Add a host-wide, token-authed GET /host/metrics local-API endpoint that
re-serves the slice-4 collector's host + per-storage view to the customer
(the de-privileged controller can't read the host itself). Add the one new
collector — CPU/chassis temperature via sysfs hwmon/thermal-zones, graceful-
null — to the shared HostMetrics struct, so the hub report carries cpu_temp_c
too. Cross-repo host-report golden updated byte-identical.

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.
