// Presentation of `StoreItem.installVerification` — the hub's
// per-entry statement of how an install would be verified under
// the CURRENT policy (computed hub-side with the same resolvers
// the install gate enforces). One mapping, used by the trust-gate
// dialog and the store card's blocked pill, so every surface
// tells the same story. (The module detail sheet routes installs
// through the dialog and needs no copy of its own.)
