The browser engine fetched one hardcoded version-0 commit and pinned the snapshot to version 0, so any table past its first checkpoint was unreadable. Delta checkpoints every ten commits by default, so that excluded most real tables and was the single largest gap between "the dependency graph works in a browser" and "this could plausibly ship". Repins delta-rs onto the checkpoint-aware prefetch and adds a fixture whose pre-checkpoint commits are deleted after checkpointing, so the expected totals are only reachable by replaying the checkpoint. Chrome and Firefox both resolve version 3 and return alpha=18,beta=23, fetching _last_checkpoint, the checkpoint parquet, and the trailing commits.
