# Make the two per-arch cx_Freeze backend trees compatible with
|
|
# @electron/universal's merge requirements:
|
|
#
|
|
# 1. Every file must exist in BOTH trees (no unique-to-one-arch files).
|
|
# 2. Every non-Mach-O file must be byte-identical across trees.
|
|
#
|
|
# Python bytecode (.pyc inside library.zip) is architecture-independent;
|
|
# only timestamps and zip metadata cause SHA differences.
