Diff and snapshot sources were excluded before scheduling, and the separate diff renderer never painted attribution. Capture per-side Git provenance, preserve private object stores for historical tabs, and reuse the current-line worker and cache.
Replace the 16 MiB comparison rejection with independent bounded per-side loading and frozen Working blobs. Bound diff computation, defer large inline highlighting, index source-row navigation, and expose actual load failures. Verified the real 52.3 MB parser through repository/session APIs and terminal rendering with EOF/start navigation.
Conflicted revisions read every file through jj file show, which returns
empty output for symlinks and causes repository-wide subprocess fanout.
Keep ordinary Git blob sources and immutable identities; render only
selected conflicted paths through jj.
Verified all 905 tests and the original local bookmark comparison with
25 correct paths in 0.522s, plus actual terminal conflict viewing.
Strict Clippy is blocked by existing diagnostics outside this change.
