wgtunnel.InstallRecoveredKey: write an escrow-recovered WG private key (create-
only, refuse-overwrite) so the tunnel re-establishes with the same identity/pubkey
(same /32), no keygen. Wired into identity-consume -install-wg-key (opt-in;
pre-S3 blob → logged fresh-keygen fallback). Value never logged.
internal/dr (new): consume the host_loss restore_directive (was logged-ignored)
into an inspectable RestorePlan via the AddConsumer raw seam — per guest
{vmid,archive,target,sizing} + per drive {durable_id→mount} + offsite PBS coord.
DERIVE-AND-SURFACE only; the Consumer has no restore/destroy dependency (execute-
nothing is structural). guest_loss/absent → no plan.
Tests + red-proofs (WG create-only overwrite; plan mode-gate). No secrets on
argv/stdout/logs. The destructive in-place restore is a separate operator-present
STOP-gated drill.
