Mobile PR #638 was merged into staging on 2026-10-12.

The set grid reads ownership without collection-wide enrichment, displays catalogue metadata independently, and mounts artwork around visible rows. Sorting is memoized and validated public metadata is cached across launches, with bounded storage, language/edition isolation and background refresh. Prices and user data are excluded from this cache.

Lint and typecheck pass. Jest: 242 suites and 2346 tests passed, with two suites and 11 tests skipped. Android manual checks covered initial images, scrolling and offline metadata after restart. The Maestro flow is included but could not run because its CLI is unavailable. iOS visual validation remains outstanding.

No native build artifacts, dependencies or backend changes are included. First-ever visits still fetch full metadata; no measured end-to-end speedup is claimed. This is not infinite-scroll pagination.
