## Description Backports #17952 to the `3.x` branch. When a block is replaced between collection versions, the version diff merged the source and replacement schemas by field name and then traversed them with the replacement block's schema path and permissions. Historical source fields—especially inside unnamed rows, collapsibles, or tabs—could therefore resolve to a missing client schema entry and throw `No client field found for ...`, surfacing as a production client application error. This backport: - renders source and replacement block schemas independently with their own schema paths and permissions - avoids merging fields from blocks with different slugs on the client - counts source removals and replacement additions independently for collection and row badges - adds unit and Playwright regression coverage for the production failure ## Testing - `pnpm exec vitest run packages/next/src/views/Version/RenderFieldsToDiff/buildVersionFields.spec.ts packages/next/src/views/Version/RenderFieldsToDiff/utilities/countChangedFields.spec.ts packages/next/src/views/Version/RenderFieldsToDiff/utilities/getFieldsForRowComparison.spec.ts packages/next/src/views/Version/RenderFieldsToDiff/utilities/fieldHasChanges.spec.ts` (33 passed) - `pnpm build:next` (5 tasks passed) - `PORT=3012 pnpm test:e2e versions --grep="should render a replaced block when both block schemas contain unnamed layouts" --workers=1` (1 passed) - scoped production ESLint (0 errors; 3 existing warnings)
