Document the 2026-06-18 incident class: a road-warrior laptop losing DNS on a network transition strands NetBird (can't resolve the coordinator FQDN), taking ubongo unreachable until DNS recovers. Adds triage (local DNS vs coordinator), device mitigations (reliable resolvers + hosts-file pin), the non-mesh LAN break-glass to ubongo, and why ubongo is relay-only (deferred mesh-hardening, not a bug) — including the break-glass rule that hardening must preserve.

mamba + work laptop enrolled in the mesh → ubongo reachable from anywhere; the
mobile-access goal is met and Phase 1 (remote access) is complete. Adds
docs/runbooks/netbird-client.md (reusable client-enrollment runbook) + STATUS/
ROADMAP flips + CLAUDE.md reading-table entry.
