`evidence-key-agreement.test.ts` cross-products 144 adversarial combinations
across the mock adapter's gate and descriptor resolver, `validateWorkingCopy`
and the shared pixel resolver -- but omitted `instant-preview.tsx`'s own gate
and descriptor resolver. That pair is byte-parallel to the adapter's (it
lives in `presentation/`, which may not import `adapters/`, so it carries its
own copy of the legacy-key predicate) and it is exactly the pair three earlier
fix rounds regressed.
`instant-preview.tsx` now exports the two expressions it already used, so the
test drives the production code rather than rebuilding it. Added assertions:
gate agreement in both array orders, descriptor equality with the adapter's,
pixel/descriptor agreement, and order independence. The one sanctioned
divergence -- the legacy static key's `assetId`, a fixed literal here versus a
registry-derived one there -- is pinned to that case rather than ignored.
Mutation-checked: breaking the legacy predicate reports 96 of 144 combinations
disagreeing, breaking the legacy descriptor path reports 64 of 144.
