f83d68d7a0 feat(base): pin the NetBird coordinator FQDN in /etc/hosts (mesh DNS-resilience)
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).

b10a33f439 feat(base): input-only forward policy + admin-addr SSH allow
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).

3b30e70ba5 feat(firewall): public zone + askari's public services in the catalog
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).

39d2ad38ca feat(base): opt-in sshd ListenAddress on the mesh IP (fail-closed)
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.

9b3f8f826f test(base): molecule coverage for the mesh concern (manage-off no-op)
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.

9b5851ba4b chore(roles): role/test hygiene from review (O16,O17,O25,O26)
- dev_env .zshrc: drop the rclone alias (not installed) and guard the direnv
  hook with `command -v direnv` so a missing direnv doesn't error every shell (O16)
- dev_env oh-my-posh: tag the zen.toml theme deploy `config` (it renders config to
  disk like the per_user dotfiles); the include now carries packages+config so a
  `--tags config` run re-renders the theme while the binary install stays packages
  only (O17). Verified via `molecule converge -- --tags config`.
- drop the non-vocabulary `tags: [verify]` from molecule verify playbooks across
  base/docker_host/public_dns/reverse_proxy (check-tags exempts molecule anyway) (O25)
- reverse_proxy templates: add the `{{ ansible_managed }}` header (ADR-024 §1.2) (O26)

make lint green; dev_env + reverse_proxy molecule green.

a111a20cc8 test(base): Molecule coverage for ssh hardening + fail2ban
Add explicit base__ssh_authorised_keys: [] default to prevent
undefined-var errors in Molecule. Extend verify.yml with sshd
drop-in validation, PasswordAuthentication check, and fail2ban
jail assertion. Pre-create /run/sshd in ssh.yml so sshd -t
works in containers before the service has ever started.
