admin e2b6c63ea2 wgtunnel: S3 Part 3 — FELHOM_WG sudoers + capabilities + config (DEFAULT OFF) + main wiring + escrow join
Sudoers: fixed-path conf install, enable/restart/disable, latest-handshakes-only
wg read (dump FORBIDDEN — the S1 incident). 6 capability-manifest entries
(Critical=false until S4 makes the tunnel load-bearing). WGTunnelConfig with
enabled=false DEFAULT (the safety gate: a v0.64.0 rollout without explicit
config is a no-op). Daemon wiring mirrors lanresolver + AddConsumer +
SetWireguardReporter; --selftest=wgtunnel single-shot. IdentityBundle
+wg_private_key (omitempty; pre-S3 blobs cannot be retrofitted — documented)
with escrow-create auto-inject (field name only in logs). Red-proof (e) run.

admin 06e0bc9c25 agent v0.51.0: local vzdump retention default (--prune-backups keep-last=3)
The preventive counterpart to host_disk + storage_fill detectors: the periodic local
whole-guest vzdump now prunes its own old archives (keep-last=3, clamped >=1) so a box
can't refill its own root via its own backups. Local target only — PBS never pruned
(resolved via ListStorage; fail-safe skip on unknown). Seeded in host-install.

admin 63aa63d0d6 agent v0.50.0: NAS network storage Part A1 (NFS/SMB automount foundation)
Host-side NFS/SMB automount of a bulk-media NAS share under /mnt/felhom-drives/<name>
(propagates into the guest via the existing shared bind), the +100000 uid recipe,
per-share liveness, and add/list/remove local-API endpoints. A NAS is a distinct class
that bypasses the drive enroll/eject/decommission/SMART/watchdog machinery.

admin 109dd853a3 v0.28.0: backup re-target → felhom-pbs (offsite DR) + operator-signed decommission
- BackupConfig.BackupTarget() defaults whole-guest backup to felhom-pbs (separate
  hardware = real DR), configurable via backup.local_backup_target; all NewBackupRunner
  sites route through it. PBS round-trip proven live (snapshot marker + restore-test +
  pct-restore) before the re-point.
- signedjobs DecommissionExecutor + ExecutorChain: makes IntentDecommissioned reachable
  ONLY via a verified operator signature (keyed by the watchdog's storage durable-id);
  felhom-opsign builds decommission params from -durable-id. Runner wiring moved below
  the intent-store open.

admin a43e9813ad v0.21.0: agent-managed split-horizon LAN resolver (internal/lanresolver)
Host-side dnsmasq the agent manages so LAN clients reach their guest directly
(same hostname + real wildcard cert, no Cloudflare hairpin). Renders local=/
+address=/ per customer (AAAA->NODATA via authoritative zone, wildcard A ->
live guest IP), forwards everything else. Manager ensures dnsmasq+base config,
discovers guest IP (pct exec ip) + domain (controller.yaml), write-if-changed +
reload. Loop (7th daemon goroutine) tracks DHCP IP changes per provisioned
guest. --selftest=lanresolver. FELHOM_DNSMASQ sudoers. Spiked live on felhom-pve.

admin 33dfd9afb3 slice 8B (agent half): /backup/due cadence policy + /backup/status phases (v0.11.0)
internal/localapi: real /backup/due (cadence; due when no successful backup or
newest older than backup.backup_cadence_seconds; false in-window after success;
failed doesn't count) + /backup/status phases (idle|running|done|failed + job
id) + POST /backup single-flight with job id. Drives the controller quiesce loop.

admin 3fecf4c713 slice 8A (agent half): local-API server + provisioning back-half (v0.10.0)
internal/localapi: per-guest local-API server (doc 03 §6) — 7 self-scoped
endpoints, hashed per-guest token store, persisted self-signed leaf with stable
SHA-256 pin, optional 6th daemon goroutine. internal/provision: back-half —
mint token, render bootstrap.json (no registry cred), write 0600, chown
100000:100000, attach pct-set bind mount (host-side, F3, no pct exec).
--selftest=provision. build-golden.sh bakes the controller image + bootstrap
unit. sudoers FELHOM_PROVISION; firewall narrowing artifact.

admin 47dd0bd244 slice 7: PBS recovery-code escrow creation (agent, Phase B) (v0.9.0 wip)
internal/escrow: zero-knowledge escrow creation. R = 10 EFF-wordlist words
(crypto/rand, ~129 bits); wrap K under R via PBS-native key change-passphrase
driven over a stdlib pty (x/sys/unix; output discarded so R can't leak, F-A2);
self-verify the blob recovers K (fingerprint match) before shipping. Opt-in (b)
R-wrapped offline copy + (a) raw paperkey. Live K is byte-unchanged (operates on
a copy). --selftest=escrow-create (-storage/-paperkey/-offline/-upload). Posture
config field (zero_knowledge default). PBSEncKeyPath helper. Grounded by the
escrow spike findings.

Tests: R entropy>=128/format/uniqueness; integration round-trip (wrap->unwrap
fingerprint match, wrong-R fails, K byte-unchanged) guarded to linux+pbc.

admin 766500dfc3 v0.6.0: slice 6 Phase B — PBS offsite tier (verify + PBS-API client + reporting)
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.

admin b527430ec7 v0.6.0-rc1: slice 6 Phase A — backup + the self-restore-test (local target)
The guest-level backup layer + the journaled self-restore-test (restore→boot→verify→
teardown) that closes "a backup you haven't restored isn't a backup". All benign
(reuses the slice-4 classifier/gate/journal; no new destructive class/crypto). Local
target only; PBS = Phase B. Restore to a NEW guest only. Backups crash-consistent.

- proxmox: DestroyLXC, VzdumpOptions.Notes (notes-template), LatestBackupVolID.
- reconcile: Engine.RunRestoreTest (journal Scratch entry BEFORE mutation; net link-down
  pre-boot; defer teardown always; benign gated destroy) + Recover extended to reap a
  leaked scratch guest (Scratch flag, special-cased before the UPID path; idempotent).
- internal/backup: runner (vzdump + archive resolve + bulk-gap = backup!=1) + cadence
  scheduler (4th daemon goroutine, default 24h) + in-memory report store.
- hub: Backup/RestoreTest filled; collector seams; cross-repo golden byte-identical +
  bidirectional key-set tests; hub handler logs a FAILED restore-test prominently.
- config BackupConfig (band 990000-990009 default); --selftest=backup / restore-test.

admin 9d6e49236c v0.5.0: slice 5 Phase B — the host-root surface (mounts + SMART + grow + destructive gate)
The privileged write surface, isolated behind a narrow, arg-validated, adversarially-
tested seam (HostOps), the same discipline as the slice-4 gate. Completes slice 5.

- internal/storage: HostOps seam + SudoHostOps (systemd .mount units by fs-UUID, detach,
  SMART, lvs) via sudoers allowlist + fixed arg vectors, no shell; NoopHostOps fallback.
- validate.go: strict UUID/mount-path/device/LVM validators + in-process systemd-escape.
  Headline test: adversarial matrix (metacharacters/traversal/malformed) refused with
  zero exec.
- smart.go: smartctl SATA + NVMe parse, UNKNOWN-degrade; lvs thin-pool metadata fill.
- observer enrichment (Observe only): fills smart + thin-pool metadata.
- watchdog: benign re-mount response off the poll path (DevicePresent probe, rate-limited).
- reconcile: ActionResize (benign, grow-only) + proxmox.ResizeLXC; destructive storage ops
  (ClassStorageWipe/Decommission) through the slice-4 gate, target-scoped; built+tested,
  inert live.
- --selftest=storage [-watch] live harness; configs/felhom-agent.sudoers; privileged.* knobs.

admin 27b68f043b v0.5.0-rc1: slice 5 Phase A — storage observe/report + watchdog (read-only, live)
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.

admin ab77fa3544 feat(hub): host-report client + collector + first daemon loop (slice 3, v0.3.0)
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.

admin f0fee7e193 feat(authz): operator signed-op verifier + durable nonce store (slice 2, v0.2.0)
internal/authz: production form of the Phase-4 SSHSIG signing primitive.

- Verifier.New/Verify with the LOCKED pipeline (namespace → allow-list by key
  material → crypto over RAW bytes → target → time → nonce LAST); each post-crypto
  stage rejects even with a valid sig; an invalid sig never burns a nonce.
- SSHSIG framing via x/crypto/ssh (no hand-rolled crypto); key-type-agnostic
  (ed25519 / sk-ssh-ed25519 / rsa / ecdsa via pub.Verify). Fixed namespace
  felhom-op-v1. Typed errors. OpBlob (fixed host_id/guest_id tags) + VerifiedOp.
- NonceStore: MemoryNonceStore + durable crash-safe FileNonceStore (fsync'd append
  log, replay-on-open, compaction, expiry-only pruning; survives restart).
- config.AuthzConfig (nonce path + pinned operational/recovery signer keys).
- Tests (14): real ssh-keygen fixture, per-stage rejection, nonce-not-burned,
  replay, persistence-across-restart, synthetic sk, byte-exactness.

Dep: golang.org/x/crypto v0.52.0 (declares go 1.25 — the Phase-4 doc's "Go 1.24.4 /
x/crypto v0.52.0" pairing doesn't build; build server upgraded to go1.26.0,
backward-compatible). Version 0.1.0 -> 0.2.0.

admin a042316d6d feat(agent): scaffold + proxmox interaction layer (slice 1)
Stand up the felhom-agent project (module gitea.dooplex.hu/admin/felhom-agent,
binary felhom-agent) and the internal/proxmox package: the typed library every
other agent module calls to talk to Proxmox.

- API-first Client (hand-rolled REST over net/http, PVEAPIToken auth) with typed
  read ops (version/nodes/status/lxc/config/storage) and async mutating ops
  (restore/vzdump/snapshot/rollback/delete-snapshot/setconfig/start/stop), each
  returning a UPID. WaitTask polls task status until stopped and asserts
  exitstatus OK (authz can surface at task exec, not the POST — phase1-2 §1.3).
- Fenced Privileged (root-CLI) backend for the THREE proven exceptions only
  (keyctl pct create, USB mount/fstab, SMART/sensors); each cites why it can't be
  the API. Fence is structural (Client never shells out, Privileged never HTTPs)
  and asserted in routing_test.go.
- TLS: SHA-256 leaf-cert pinning or CA file; insecure mode explicit + off by
  default. No blanket verification disable.
- 403 -> privilege-named APIError; failed task -> privilege-named TaskError.
- JSON config + env overrides (token never logged); slog logging.
- cmd/felhom-agent --selftest (read-only health report) + gated --selftest=task
  (reversible snapshot/rollback/delete exercise of WaitTask). No daemon loop yet.
- Types grounded in the spike findings and exact JSON shapes captured live from
  demo-felhom (PVE 9.2.2). Unit tests use a mock transport + runner.
