// Stored-status normalization — "warn" verdicts must survive the cache
// ═══════════════════════════════════════════════════════════════════════════
// Bug (2026-08-22): getCachedTextModeration() narrowed its return type to
// "clean" | "flagged". A stored "warn" verdict with flags (e.g.
// ["conflict_instigation"]) fell into the legacy `flags.length === 0 ?
// clean : flagged` branch and was read back as FLAGGED. Downstream this
// broke auto-delete eligibility gating and mislabelled warnings on the
// dashboard.
//
// Fix: normalizeStoredStatus() accepts the full clean/warn/flagged union;
// unknown/legacy values still derive from flags.
