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.

B3: Lookup re-reads the append-only store once on a miss (cross-process
coherence with the one-shot provisioner; size short-circuit bounds the cost;
behind the TokenAuthority seam). B2: fenced mkdir -p /var/lib/vz/snippets
before the snippet install + the one narrow sudoers grant. Both red-proofed;
drill findings DRILL-day0-cleanroom-2026-07-03 B3/B2.

From AUDIT-blast-radius-hostroot-localapi-2026-07-02.md. Each fix ships with a
non-hollow test + a companion red-proof (shown failing on the pre-fix impl).
Sudoers install-source grants became globs — deploy the sudoers drop-in with
the binary. A1 (stale-lock pool-membership) deliberately excluded (spike).

Impl-1. Format now runs a mandatory unclaimed-disk guard (internal/storage/claim.go:
SystemDisks + lsblk member-FSTYPE + foreign-mount + RO + pvs/zpool; fail-safe →
CLAIMED) before any mkfs — refuses the OS disk / LVM PV / ZFS-mdraid member /
foreign-mounted device even when non-data-bearing (guard sits in Format, not the
handler). Below the agent, mkfs goes ONLY through configs/felhom-mkfs-guarded.sh
(sudoers no longer allowlists raw mkfs.*), which re-checks the catastrophic cases
as root. Read-only pvs/zpool added to FELHOM_DISK. Tests + red-proof; capability
manifest updated. go build/vet/test clean.

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.

F2-b: at startup, recover a guest left with a stale vzdump lock by a
reboot-during-backup — pct unlock -> delete dangling vzdump snapshot ->
start iff onboot, guarded by a no-vzdump-running invariant (fail-safe).
New internal/localapi/stalelock.go; proxmox GuestConfig.Lock()/OnBoot(),
ListSnapshots, ListRunningTasks, Snapshot type. New narrow sudoers grant
FELHOM_STALELOCK (pct unlock) + Critical capability stalelock-unlock.
F2-a: EnsureSharedParent only redeployed the boot script when the UNIT
differed, so the v0.36.6 make-private fix never reached hosts whose unit
was current -> /mnt/felhom-drives stayed in root's shared:1 and doubled
every drive bind. New sharedParentInstallStale compares BOTH script and
unit. Boot-time-only; never churns the live mount.
Both root causes confirmed live on felhom-pve before fixing. Green gate
(build/vet/test) all pass.

writeImage drops bash -c/printf for GuestExecStdin(img+\n -> tee /etc/felhom-controller-image);
new Runner.RunStdin/GuestExecStdin route stdin through the fenced sudo -n runner. 5 narrow,
auditable sudoers grants (no general pct exec, no bash -c) + capability manifest entries (Critical)
so the self-probe watches them and the build-test asserts coverage (companion red-proof). No
controller change; swap orchestration/rollback/state unchanged. Spike GO.

Root cause of multi-drive flapping: lxc-info absent from the allowlist → empty guest
PID → bound_under_parent=false for every drive → controller gate stops apps. Audit-driven
completeness pass; surfaces GuestExec/pct-exec (controller-swap) for operator decision.
No binary change.

Bare commas are command separators in sudoers; the lvs/lsblk -o option lists need
escaped commas. The file had never been visudo-validated live (the demo host ran the
agent root+direct). Surfaced by the BUNDLE host-install visudo -cf gate.

Replaces the per-drive 'pct set -mpN' bind with ONE permanent parent bind
/mnt/felhom-drives plus host-side felhom-data swaps underneath it (propagates
into the running guest live, no pct, no reboot; C1-immune; confined; fail-closed
when absent). EnsureSharedParent installs a boot unit ordered Before=pve-guests.
ReassertGuestBinds is now a pure host-side reconcile. /disks reports GuestPath +
BoundUnderParent for the controller repoint+gate. Non-hollow tests + companions.

Pre-start PVE hookscript (internal/guesthook) creates host-root placeholders for
absent bind-mount sources so the guest always boots (fail-closed); decommission
now pct set --delete's the dead mp (GuestBinder.DetachBind) so a missing source
can't brick the next reboot (B3 C1 bug). Non-hollow tests + companions. Installed
+ registered per-guest by the provision back-half. Transitional ahead of the
intermediary-mount re-architecture which makes C1 structural.

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.
