  Defaults path to cwd; auto-detects domain from project charter if
  --domain is omitted. Does: API health → topic lookup → MCP check →
  CLAUDE.md from template → progress event.

custodian status
  Prints API health + summary totals + blocking decisions.

Installed via: make install-cli (symlinks .venv/bin/custodian → ~/.local/bin/)
Entry point declared in pyproject.toml [project.scripts].
