# Get Co Changes

`GET /snapshots/{snapshot_id}/co-changes`

Co-change pairs from `git_metadata.co_change_partners_json`.

With `?file=...`, returns the partners that historically change with
that file (one row per partner). Without, returns the top global
pairs ranked by `co_change_count`, deduplicated as undirected pairs.

``co_change_count`` is the number of shared commits, not the indexer's
decay-weighted score. The client renders it as "x N", so a count is the only
reading that makes the label true; the weighted score is what the coupling
graph surfaces as ``strength``.
