Boundary

Reaches into domain, platform.

Shares tier application with 120 other crates: application-agreements, application-ai, application-analytics, application-approvals, application-assessments, application-audit-log, application-auth, application-billing, … (120 total).

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

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.
