// TestStorageWarningWireTextIsFrozen — localisation slice 2 (R-557), scenario S6.
//
// `HealthReport.Warnings` is ON THE WIRE: report/builder.go copies it into `health.warnings`, the hub
// stores it and the operator reads it there. The rule for slice 2 is that nothing on the wire moves —
// so these five sentences may NOT become bundle keys the way a page's copy does, however English the
// household's dashboard is.
//
// The golden below was captured from this file at 736f54b49610, the base commit of v0.252.0, BEFORE
// any conversion. It is the measurement, not a restatement of the code: a rewording, a re-punctuation
// or a translation of any producer in checkStoragePaths fails here and prints both strings.
//
// What the DASHBOARD shows for these warnings follows the language by a different route — the kinds
// beside them (WarnKind*, internal, never on the wire) plus the parameters, so the page can render its
// own sentence without the wire text changing. See internal/web/alerts.go.

// TestStorageWarningFormatsAreFrozen pins the three producers the table above cannot reach on every
