Merged with the local block-merge tool (`merge_sdxl_mbw.py`); full block weights and rebuild commands are in the embedded checkpoint metadata. Recipe is reconstructed from preserved lineage notes + embedded metadata, not a pasted terminal transcript, so treat bit-identical rebuild as best-known rather than guaranteed.
