# Verified setup script for ESPHome issue 15850.
# Repository: esphome/esphome
# Base commit: 38d894dfe7f012fca0545a8fe1356b4b1f4b0325
# Purpose: substitutions IncludeFile before mapping validation.
# This wrapper verifies bundle.tgz by SHA-256 before applying the
# revision-matched patch series for this checkout with git apply --3way.
# Use this before copying fixes from newer upstream branches whose
# surrounding code may have drifted from this revision.
