# Pre13 L-B

This batch completes the planned semantic aliases for internal EROFS NIDs and
byte offsets. Each changed object was selected from the Pre13 variable-level
whitelist.

The aliases remain unsigned 64-bit types. No expression, cast, format string,
error path, field order, or control flow changed. File sizes, lengths, chunk
and extent indexes/counts, directory cookies, media sizes, timestamps, disk
fields, and overflow-only temporaries retain their previous types.

Declarations and definitions were updated together. The resulting source diff
contains only type tokens, line wrapping required by those tokens, and this
record.

No build, QEMU, smoke, or feature test was run for this batch.
