Deterministic Unified Diff Generation

Generate a minimal line-edit unified diff using bounded LCS and deletion-first tie breaking.

Generate a minimal line-edit unified diff using bounded LCS and deletion-first tie breaking. Line identity includes its terminating LF. Hunk ranges merge when their context windows overlap or touch. At most 65536 line-pair cells; identical text yields an empty patch. Output is replay-verified against the new text, with no promise of byte-for-byte GNU output. One supplied LF-only text document, at most 16000 UTF8 bytes, 256 lines and 2000 characters per line; patches at most 30000 bytes and 64 hunks. BOM, tabs, spaces and terminal-newline state are preserved. NUL/CR, multi-file/Git/binary/combined patches are excluded. Filenames are opaque labels. No filesystem, repository, network access or execution. Use authorized, non-sensitive data. The report describes supplied records and does not change external systems.
