// Scope: inspect diagnostics report schema and text rendering.
// Targets: `client/src/launcher/diagnostics/*`.
// Why: when a remote call looks wrong, Copy Report should preserve enough
// routing, media, calibration, timing, and recommendation context to debug
// without spelunking live logs first.
