# Pre11 Batch D

## Scope

- Rename `src/lz4.c` to `src/decompressor_lz4.c`.
- Update the source list and current architecture references to the new filename.

## Equivalence

- The pre-rename `lz4.c` blob and renamed `decompressor_lz4.c` blob are identical.
- Byte comparison confirms the renamed source content is unchanged.
- Rename detection reports a 100% rename.
- LZ4 definitions, declarations, descriptor references, and `lz4_finish` call counts are unchanged.

## Behavior and Testing

- This batch changes filenames and documentation only; it makes no behavior changes.
- No build, QEMU run, feature test, or other test was run.
