graph.json is written "directed": false and carries direction in arc order
(#563), or in _src/_tgt markers on legacy files (#2309). A plain undirected
node_link_graph load re-orders endpoints by node-list position, so every
link whose target precedes its source in the node list came back reversed
(79% of links on graphify's own graph).
query, path/explain, affected, merge-graphs and the MCP server already
restore direction. The remaining reloaders did not:
- export html / neo4j / falkordb (cypher.txt and --push) / obsidian canvas
- graph.html re-rendered by update, watch and the git hooks
- the git merge driver, which wrote the reversal into the committed
graph.json, even when merging three identical copies
Add paths.restore_arc_direction, the inline idiom query and merge-graphs
already use, and apply it in load_node_link_graph and the export loader.
to_cypher, to_canvas and push_to_neo4j/falkordb now read _src/_tgt as
to_html already does. The merge driver writes direction back into arc
order before saving, as to_json does, so the committed file keeps the
post-#563 convention.
global add has the same bug and is fixed separately.
