//! Provenance tag carried by every entry a scanner reports.
//!
//! See ISSUE-01F8K0WCA2BNB for the full design: a workspace may merge
//! records from its writable home with read-only union sources. Each
//! scanned entry tells consumers which side it came from, so reads can
//! display it, writes can refuse it, and link rules can apply the
//! asymmetric cross-reference policy.

/// Where a scanned entry was sourced from.
