The registry index (schema v3) can now carry a review object per entry
(reviewer, date, sha256, optional commit/notes) asserting that someone
inspected the exact artifact being listed. The stamp is bound to the
artifact hash: review.sha256 must equal the entry sha256, so any change
to the released zip invalidates the review.
- registry_service: keep review through normalization (validated),
derive trust per entry: first_party, reviewed (stamp matches the
pinned hash), or unreviewed
- marketplace install route: unreviewed (or sha256-less) entries return
409 requires_acknowledgment unless the admin posts
acknowledge_risk: true; acknowledged installs record trust in the
audit log. Consent gate, consistent with ADR 0002
- Marketplace UI: Reviewed badge (reviewer + date tooltip) and
Unreviewed warning badge on registry cards, plus a risk confirmation
modal that retries the install with acknowledge_risk
- tests: trust derivation and the install gate (409 + acknowledge path)
- docs: EXTENSIONS_REGISTRY.md documents the field and the flow
