Invalid graph structure

Graph storage, identity or registry metadata is invalid. Decoding or the requested command fails; validation alone reports problems without rewriting the graph.

#Common causes

• The document is not a graph, lacks g_meta, or contains unexpected records or malformed field data.
• A node has an invalid n_ ID or zero version, a subgraph reference lacks its path or ID, or the header names a different domain adapter.
• A registry entry repeats a kind/version or lacks types or documentation; a command supplies the wrong ID prefix, an empty parameter key or a nonfinite position.

#Fixes

• Correct the reported record or command argument: use n_ node IDs, w_ edge IDs, positive versions and full @path#id subgraph references.

• Load the matching graph and domain adapter; apply snapshots only to the graph with the same asset ID.

• Give each registered kind/version unique, documented metadata and use finite coordinates with graph.node.move.
