/**
 * Unit tests for the e2e bridge's mock `search_messages` predicate.
 *
 * The mock stands in for the relay in identity-less E2E runs, so its `since` /
 * `until` comparators must match the relay's inclusive NIP-01 bounds
 * (`crates/buzz-core/src/filter.rs` keeps `since <= created_at <= until`).
 * `before:YYYY-MM-DD` gets its exclusivity from `parseSearchOperators`, which
 * emits `localMidnight - 1`; a mock that also excluded its own bound would
 * drop the last second of the range that production returns.
