Consumer side of the catalog-projection seam (C1): - catalogProjectionCache now wraps ProjectionStore[catalog.Projection] (identity transform — the cart's overlay uses ~all fields); delivery handler routes bus frames via HandleFrame (snapshot begin|chunk|end + epoch-stamped deltas). - Per-pod cold-start-ready .bin under CART_PROJECTION_DIR (pod-local, never shared) + IsDeleted tombstone passthrough; HTTP fetch demoted to last-resort. - Tests: test-only Apply shim + mustCache helper keep existing cases green; new snapshot-framing integration test.
