Three coordinated changes addressing follow-ups from the 2026-05-21 netbird vanilla
migration, plus a related off-LAN ergonomics fix:
bin/homelab:
- New ssh_target(name, force_mesh=False) helper resolves (addr, port, user)
from inventory, honoring ssh.netbird_port (forces mesh path) and ssh.user
(default "root"). Falls back to the netbird FQDN when LAN IP fails a
cached 1.5s TCP probe — helps off-LAN operators on VPN/symmetric-NAT
paths where the netbird subnet route doesn't reach 192.168.8.0/24.
- New ssh_base() builds the full `ssh ... user@addr` invocation; hubris_ssh()
is now a back-compat shim. cmd_ssh, cmd_logs, cmd_restart, cmd_nuke
refactored to use it — no more hardcoded "root@" anywhere.
inventory.yaml:
- New ssh.user convention (root by default, explicit per workstation).
- hubris.ssh.user=root (explicit, documents convention).
- republic-laptop, mac-mini: ssh.user=dtoro. ludo-mini left default (TODO).
- Comment block in the header explains the field + why it exists (netbird-ssh
defaults to LOCAL username; "user not found" on LXCs is the gotcha).
- hosts/*.yaml regenerated from build_host_files.py.
infrastructure/mesh.md:
- Migration changelog entry updated: Device Code Stage is now configured
(was "NOT yet" — landed in d41d73f); --setup-key no longer required.
- New subsection documenting the post-migration JWT-issuer cache bug:
client/internal/engine_ssh.go's updateSSH() bails out when sshServer is
already running, so systemctl restart and netbird down/up don't refresh
the SSH JWT validator. Full daemon stop/start is the fix.
- Companion username gotcha (`netbird ssh` defaulting to local username).
operations/agent-enrollment.md:
- Three new troubleshooting rows: JWT-issuer cache, user-not-found, and
LAN-unreachable-from-mesh-peer (the new homelab CLI behavior).
Verification: ssh_target resolution against the live inventory yields
- hubris → ssh -p 22022 root@proxmox-server.netbird.selfhosted (mesh-forced)
- jellyfin/gitea → ssh root@192.168.8.x (LAN reachable, probe passed)
- republic-laptop/mac-mini → ssh dtoro@<fqdn> (per ssh.user)
- ludo-mini → ssh root@<fqdn> (default)
Audit against actual netbird+tailscale peer lists:
- hubris is the only LXC-host on Netbird; only workstations + hubris
have netbird entries
- 10 LXCs+VMs have real Tailscale FQDNs: apps, jellyfin, paperless,
gitea, nextcloud, elementsynapse, sophia, mule-images→muleimage,
arriman→arr, haos→homeassistant
- 7 hosts are LAN-only (no mesh block): nfs-export, caddy, claudio-bot,
authentik, plato, mule-photos-new, zimaos
- mac-mini's netbird FQDN corrected to the actual peer name
(mac-mini-234-17.netbird.selfhosted)
Also: bin/homelab host_address() now prefers lan_ip first — universally
reachable from any LAN client and from any Netbird peer via the
192.168.8.0/24 network resource routed through hubris. Mesh FQDNs are
fallbacks for roaming workstations without a fixed lan_ip.
This makes 'homelab status' from republic show all backends 'ok' instead
of falsely reporting them 'down' against unresolvable netbird FQDNs.

Caddy + split-horizon DNS now resolve these to LXC 105 (via 121).
Workstations off-LAN reach them via Netbird (192.168.8.0/24 is a
network resource routed through hubris).

Add the foundation for distributing homelab context to every client
(LXCs, VMs, workstations including republic-laptop, mac-mini, ludo-mini)
with a single source of truth, structured query layer (MCP), and per-client
age-key issuance for secrets:
- inventory.yaml — canonical topology (hosts, services, mesh addresses)
- hosts/*.yaml — per-host identity files generated from inventory by
mcp/build_host_files.py; do not edit by hand
- AGENTS.md — orientation doc symlinked to /root/AGENTS.md on every client
- bootstrap.sh — one-shot enroll (Linux + macOS), clones repo, fetches age
key from issuance, installs sync timer/launchd job, drops the homelab CLI
- bin/homelab — single-binary Python CLI: whoami, list, ssh, pct, logs,
restart, open, status, secret, sync, mcp, client add/remove, nuke
- mcp/server.py — FastMCP server: context tools + read-only management
tools (no mutations exposed); shell-outs use mcp-reader restricted ssh key
- mcp/deploy/ — claudio-monitor-style gitea webhook deploy scaffold for the
MCP service on LXC 105 (ports 9810 mcp, 9811 webhook)
- secrets-issuance/ — per-client age key auto-provisioning over the mesh;
source-IP gated against inventory, with denylist for revoked clients
(ports 9820 issue, 9821 webhook)
- secrets/, .sops.yaml — SOPS recipient scaffolding; the operator fills in
age public keys after Phase 3a generates them
- scripts/sync/ — systemd timer (Linux) + launchd plist (macOS) pulling
/opt/homelab-context every 5 min
Mesh: both Netbird (preferred, 100.122.0.0/16) and Tailscale accepted
during the in-flight migration; no client is gated on completing the move.
