# Build Architecture Guard Script
#
# Author: Matthew Raymer
# Date: 2025-08-22
# Purpose: Protects build-critical files by requiring BUILDING.md updates
# Enhanced to protect Android build system including asset validation,
# API routing, and resource generation logic
#
# Usage:
# ./scripts/build-arch-guard.sh --staged # Check staged files (pre-commit)
# ./scripts/build-arch-guard.sh --range # Check range (pre-push)
# ./scripts/build-arch-guard.sh # Check working directory
#
set -euo pipefail
# Sensitive paths that require BUILDING.md updates when modified
