What it is for

This crate does not document itself. No //! block on its entry point. The facts below are complete; the reason this crate exists is not written down anywhere, and belongs in src/lib.rs rather than here.

Boundary

Reaches into foundation.

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._

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	`domain_privacy_research`	`src/lib.rs`

Error model

Error type	Named by
`PrivacyResearchError`	declared, no public signature returns it

Operational characteristics

Property	Evidence
async public surface	yes
async runtime	none detected
database access	yes
network I/O	none detected
unsafe code	none detected
environment variables	none detected

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

3 workspace crates depend on this one: application-privacy-research, operations-privacy-scan-runner, platform-privacy-scan-api.
