Adds base__mesh_coordinator_pin (default empty = no-op). When set + base__mesh_enabled,
a lineinfile task writes "<ip> <fqdn>" to /etc/hosts so a managed mesh host survives a
local-DNS hiccup (the 2026-06-18 incident class). FQDN derived from base__mesh_management_url
via regex_replace (no community.general). Gated on base__mesh_enabled | bool and pin length;
the coordinator host (askari/offsite_hosts) stays exempt. Production pin wired for ubongo
(77.42.120.136). Molecule dns_servers fix included (Docker/NetBird DNS incompatibility).

base__firewall_input_only renders the forward chain policy accept (host-local
INPUT filtering only) for hosts that forward container/NAT traffic; defaults
false so real service hosts keep the forward default-deny. base__firewall_admin_addrs
adds operator-workstation LAN sources to the SSH allow-list alongside wt0 +
ssh-from-control. Molecule locks the secure default + the admin rule.
Mesh-hardening 2/3 (ADR-020/021).

Adds a public (0.0.0.0/0) zone and askari's Caddy (80/443) + NetBird STUN
(3478/udp) ingress so the base nftables default-deny does not drop the live
public services when applied to askari. Molecule + filter unit test cover the
public-zone rendering. Mesh-hardening 1/3 (ADR-020/024/016).

base__ssh_listen_mesh_only binds sshd to the live wt0 IP only, with
ip_nonlocal_bind to beat the post-boot bind race and a fail-closed assert so an
unresolved address never silently listens on all interfaces. Molecule covers
the render + sysctl. Mesh-hardening 1/3 (ADR-016/021).
Environmental checkpoint applied: the molecule-debian13 container image lacks
procps (no sysctl binary). Added molecule/default/prepare.yml to install procps
and sysctls: {net.ipv4.ip_nonlocal_bind: "0"} to molecule.yml platform so the
ansible.posix.sysctl task can write and read back the value hermetically.
Sysctl file format is net.ipv4.ip_nonlocal_bind=1 (no spaces); verify.yml
grep pattern updated to match ansible.posix.sysctl's actual output.

Converge enables mesh with base__mesh_manage:false (+ dummy key) so the include
path runs hermetically; verify asserts netbird is not installed — proving the
concern is a clean no-op when the live actions are gated off. Existing firewall/
ssh/fail2ban assertions unaffected.

nft -c rejects iif "wt0" when the interface is absent (container, or any host
before NetBird); iifname matches by name and is robust to wt0 coming/going.
Drop the ansible_host fixture override (the docker connection uses it as the
container name) — molecule covers zone resolution, pytest covers service->IP.
