# Unified Diff

## Fixture

`unified_diff_router_change` models a patch with long unchanged context around a
small configuration change.

## Behind The Scenes

The diff compressor keeps patch structure: file headers, index lines, hunk
headers, and changed lines. Long runs of unchanged context are collapsed to a
small anchor plus an omission marker.

That preserves what review agents usually need first: which file changed, which
hunk changed, and the exact added/removed lines. The surrounding context remains
available via CCR if the agent needs to inspect it.

## Human Review Notes

The changed lines must be exact. A reviewer should confirm that file headers,
hunk headers, and both the removed and added `ccr_enabled` lines are still
visible. The omitted context markers are acceptable because they describe what
was dropped and the full diff is recoverable.
