A managed box's IP was invisible in every operator surface because nothing
reported one: HostMetrics carried node/cpu/mem/disk/load/uptime/temp/wrapper-sha
and no address of any kind. The hub could not show a host's LAN IP anywhere.
Two things that looked like the answer are traps, both checked before writing
code: lan_resolver.host_ip is an OPTIONAL config value absent unless that feature
is configured, and DeriveHostIP(local_api.listen_addr) returns 169.254.253.1 —
since R-50 the local API binds a link-local address identical on every box. Both
would have produced a confident wrong answer.
New wire field addresses[], one entry per (interface, address). Deliberately
iface+cidr rather than a single lan_ip: a Proxmox host legitimately holds several
(management bridge, tailnet, WG tunnel) and picking one to call "the" LAN IP is a
guess the agent is not entitled to make — silently wrong on a box whose bridge is
not vmbr0. The agent reports what exists; the hub does the labelling.
The filter is one predicate, chosen by MEASURING both demo hosts rather than by
reasoning about interface names. IsGlobalUnicast() alone drops loopback, IPv6
link-local (one per bridge, pure noise) and IPv4 link-local (169.254/16 — exactly
the island address above). It needs no veth/fwbr/tap denylist: that per-guest
plumbing carries no IP at all and self-excludes, verified on both boxes.
No new privilege and no block I/O — net.Interfaces() is a netlink/procfs read, so
the sudoers fence is untouched and the health-check rule is honoured.
The seam DEFAULTS to the real enumerator, inverting the nil-reporter-means-off
convention: this stanza has no config gate, so a forgotten wiring call would have
shipped it silently empty — the inert-seam failure recorded four times here.
Cross-repo: the golden is duplicated byte-identically in felhom.eu and the
contract test fails on top-level key drift, so both goldens moved together and
addresses[0]'s key set is asserted bidirectionally. The field marshals as [],
never null — the repo's own no-nulls invariant caught that on the first run.
Tests +9; three red-proofs (global-unicast filter, down-interface guard, inert
collectAddresses) each run, observed failing, and reverted.
Both defects were live on both demo boxes: the recipe said namespace "root" while
storage.cfg said demo-felhom/demo-hp, and it never named which of two content=backup
dir storages holds the local archives.
R-106: the namespace came from the listed snapshot, but PBS omits `ns` per item once
the list is namespace-scoped, so it was always empty and normalised to "root". It now
resolves from the pbs STORAGE (storage.cfg's `namespace`) — the same field vzdump makes
PVE read, so the recipe cannot disagree with the backup.
R-109: backup_target resolves from the primary tier of cfg.Backup.BackupTiers(), the
function the scheduler consults, and carries the mountpoint that separates /mnt/hdd_1
from /var/lib/vz. The resolver reports the tier IN EFFECT (daemon-start config), not
agent.json on disk — a target move rewrites the file and deliberately does not restart.
Unresolvable is recorded as unresolvable: resolved|unknown plus a distinct reason,
never a default, an empty string, or a placeholder.
Needs hub v0.83.0 — AssembleDRRecipe allow-lists top-level keys, so backup_target
would otherwise be stored intact and dropped before any operator saw it.
9 tests, 4 red-proofs (each mutation asserted to have landed). Suite rc=0, 29 ok.
key.go: create-once 0600/0700, corrupt-refusal (never overwrite — may be escrowed
identity), clamp for CANONICAL STORED form (x/crypto X25519 clamps derivation
internally — discovered during red-proof (c); the stored-clamped test is the
real anchor). Fixed vectors generated with real wg pubkey (provenance in test).
hub: WireDesiredState.Wireguard + WireguardStatus report stanza + RegisterWG
client (typed errors, token-free). S2 golden copied BYTE-IDENTICAL + field-exact
decode test.

HostReport.LeafFingerprint rides the served fp (from EnsureLeaf) on every report; empty when local
API disabled. Collector.SetLeafFingerprint threads it like Capabilities. Hub watches it for a re-key.

New internal/capability: Manifest of required sudo -n grants + Prober that LISTS each
via 'sudo -n -l' (never executes) + binary-exists check → ok/degraded snapshot on the hub
report. Build-time test asserts manifest⊆sudoers (red-proof: dropping lxc-info FAILs the
gate). Startup logs N/N ok + ERROR per degraded. Serve-degraded; no allowlist change.

Live PBS coord: new internal/pbs/live_reporter.go (LiveSnapshotReporter implements
hub.PBSReporter via the cheap Client.Snapshots() list with last-known-good fallback,
bounded by an 8s timeout, list-only — never triggers a verify). Closes the gap where
the recipe's pbs block was omitted whenever the verify-loop SnapshotStore was empty
(one-shot collect + the first ~6h after a daemon restart). SnapshotStore.Get added
(per-datastore LKG). Wired into the collector in both runDaemon and runSelftestHub;
the verify loop keeps Recording into the SAME shared store via one hoisted pbsTargets.
v1 host-half drive shape: dropped drives[].role (hub/operator-owned manifest concept,
not host-derivable) and drives[].restic_repo_coord (named a backup tier that doesn't
exist). Drive shape is now {durable_id, mount_path, intent, fs_type?, total_bytes}.
Hub reads drives as json.RawMessage → no hub struct change; goldens re-pinned
byte-identical (agent + hub copies).
Tests: live_reporter_test.go (T1 load-bearing coord-without-verify + T2..T6),
TestDRRecipeHostHalf_V1DriveShape; each companion demonstrated to fail pre-fix then
reverted. go build/vet/test green.

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.

The control envelope becomes live: the agent caches the hub's desired-state +
generation and re-fetches GET /hosts/{id}/desired-state only when the
generation advances. A new internal/desired Syncer maps the wire shape into a
reconcile.CachingProvider feeding the engine; benign deltas reconcile, an
explicit guest decommission is gated pending_signature (exec is 10B). Adds the
DesiredStateResponse/WireDesiredState wire types + Client.FetchDesiredState +
the loop EnvelopeObserver seam. Cross-repo golden (envelope + desired-state)
byte-identical with the hub.

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.

Adds the two new RestoreTest wire keys to the shared host-report golden and exercises
them in the bidirectional key-set contract test. Kept byte-identical with felhom-hub's
copy (sha256 e6999d77...). Testdata/tests only — the v0.7.0 binary is unchanged.

Spike-proven that backup/restore-to-PBS reuse Phase A unchanged; the only new code is
the verify capability, a small PBS-API client, and PBSSnapshot reporting.
- internal/pbs: fingerprint-pinned, token-authed PBS-API client (Verify/Snapshots/
TaskStatus, node-from-UPID; secret read from /etc/pve/priv/storage/<id>.pw at runtime,
never logged) + the verify maintenance loop (own cadence, default 6h, NOT gated/journaled,
like the watchdog) + SnapshotStore.
- hub: PBSSnapshot filled (namespace/type/id/time/size/owner/protected/encrypted/
verify_state/verify_upid); PBSReporter collector seam; cross-repo golden + bidirectional
key-set tests; hub handler parses pbs_snapshots + logs a failed-verify WARN.
- backup: report the ACTUAL vzdump mode (parsed from the task log; PVE may downgrade
snapshot->stop). proxmox.Storage.Username. config PBSVerifyCadence/secret-dir.
--selftest=pbs-verify. Backup/restore-to-PBS unchanged.

Fill the slice-3 storage_targets stub and add the fast-poll storage watchdog.
Read-only this phase; the host-root surface (mounts/SMART/grow/destructive gate)
is Phase B. Hub-owned desired manifest is slice 10, so reconcile against it is
built-but-unfed.
- internal/storage: StorageTarget wire contract, durable_id derivation per type,
HostReader seam (procfs/sysfs, root-free), Observer (storage_targets from
ListStorage/NodeStorage + host reads, lvmthin thin-pool fill), and the watchdog
(third daemon goroutine; debounced out-of-band report on a known target's
attach/disconnect transition).
- proxmox.Storage: additive parse-only config fields (durable_id sources).
- collector StorageObserver seam; Loop.SetTrigger out-of-band report; daemon runs
the watchdog as a third goroutine; StorageConfig knobs.
- cross-repo golden kept byte-identical with felhom.eu/hub; bidirectional key-set test.
