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.
