Bare `reach` and bare `reach <domain>` printed help and exited 2, Click's usage-error convention. Running reach with no arguments is the DISCOVERY action — it is how the tool gets learned from nothing — and a caller that branches on exit status would read its own onboarding as a failure. Now they exit 0. D-263's exit-code contract is untouched: it governs failures, and printing a command list is not one. Verified across the whole matrix, because this change flirts with the exit-0 trap that record opens with — bare 0, bare domain 0, --help 0, unknown domain 2, unknown verb 2, real failure 1. All five are now pinned as a sixth conformance invariant, since an exit code regresses silently and nothing else would notice. Proven to fail by putting the 2 back. The implementation also collapses a duplicated class. core/cli.py holds ReachGroup with both shared behaviours — no-args-prints-help-and-exits-0, and unknown-name-enumerates — and LazyDomainGroup now extends it instead of subclassing TyperGroup directly, keeping only the laziness and the domain-specific wording. The enumeration logic previously existed twice in slightly different forms, which is how the root and the domains would have drifted into disagreeing about their own conventions.
