//! Module: db::diagnostics::tests::execution_trace
//! Covers outward execution-trace metrics projection on the diagnostics
//! surface.
//! Does not own: execution-trace implementation details outside the published
//! diagnostics DTO surface.
//! Boundary: keeps diagnostics-surface regressions in the diagnostics owner
//! `tests/` boundary.
