How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Boundary

Reaches into foundation, identity.

Shares tier domain with 41 other crates: domain-agreements, domain-ai-report, domain-billing, domain-catalog, domain-classify, domain-comments, domain-competitive-intel, domain-contact, … (41 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
