pub fn bundle_from_checkpoint(root: &Path) -> Result<Value, String>Expand description
Rehydrate a checkpoint directory into the standard benchmark bundle,
including a partial state — an in-progress or preflight-failed
checkpoint rehydrates fine, with whatever rows/records/aggregates are
available so far. The bundle gains a "checkpoint": {status, counts}
block (and h2h_pairs when the manifest carries one).
