Boundary

Reaches into operations, platform.

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

Targets

Kind	Name	Source
lib	`application_approvals`	`src/lib.rs`
test	`pg_forge_approvals`	`tests/pg_forge_approvals.rs`

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

Property	Evidence
async public surface	yes
async runtime	none detected
