One-click installs showed no trust signal at all (top security
finding of the usertest panel). Every install path — store card,
detail sheet, and the flow list's quick fix — now routes through
one confirmation dialog showing what the hub actually knows
before download: origin store, version, license, maturity, and
required services/capabilities, plus the sandbox model and an
honest note that per-entry signature status is not in the store
index yet (verification happens hub-side at install). Widget
tests cover content and confirm/cancel semantics.
