pub fn severity_for(kind: HwndDriftKind) -> SeverityExpand description
Phase B.9.1 — per-kind severity classifier. The split is
deliberate: OrphanDestroy and HwndWithoutBrowser indicate a
real divergence between CEF identity and Win32 reality (a CEF
bug or a missed report path) — ERROR. OffMonitor,
HiddenSinceOpen, LingeringHwnd are operationally
significant (user can’t see / use the window) but don’t
indicate a state-machine bug — WARN. BrowserWithoutHwnd is
commonly transient (race window between OS create and host
link) — INFO; only meaningful if it doesn’t reconcile.
