// SCOPE (fork R-A): this-bank only — the sole surfaced verb. The RemoveScope::AllBanks

// CONFIRM-ON-LAST-REFERENCE (guardrail): a remove that would orphan a file (no OTHER
// bank references its content hash after the remove) earns a confirm; a remove of a
// still-referenced sample does not. BATCH UX: for a multi-select we compute the
// last-reference set BEFORE mutating (removal changes the reference graph), then fire a
// SINGLE confirm summarizing the N that would orphan — not one dialog per sample. If
// none would orphan, no confirm fires at all (the confirm is earned by actual risk).
// SILENT REMOVE: removes proceed without a confirm dialog. Recoverability is provided
// by the batched REAPER undo (R-B) — one Ctrl-Z restores the index entry. Files are
// never deleted by remove (orphaned-until-prune is unchanged). hashReferencedElsewhere
// is a tested model API retained for Phase R prune; it has no shell caller here.
