Module resolve_undo 

Git index REUC (resolve-undo) extension — records unmerged stages when a conflict is resolved.

Format matches Git’s resolve-undo.c: for each path, NUL-terminated name, three octal modes with NUL terminators, then raw SHA-1s for non-zero modes.

Structs

record_resolve_undo_for_entry

Merge one unmerged index entry into the resolve-undo map for its path.

write_resolve_undo_payload
