unflatten_tree

unflatten_tree(serial_tree, unprep_tree=True, max_leaf_elements=None, block_pointers=None, prefix_filter=None, jump_table=None, record=None): 

Replay traversal markers and per-key shape/value pointers to rebuild the nested tree and restore list/None sentinels.

If jump_table and record are both given, resumes the walk directly at that record’s span instead of starting from the beginning – no need to replay everything before it.

• serial_tree: Any

  flat-tree metadata and arrays. NOT mutated (key_map is read, not popped), so this can be called repeatedly against the same loaded data.

• unprep_tree: Any

  whether numbered list dictionaries should be restored

• jump_table: Any

  optional dict from build_jump_table

• record: Any

  optional path string to jump to (requires jump_table)

• :returns: _

  the reconstructed nested dict
