# verify.sh — One gate before committing: clean build (0 warnings) + full test run + scope check.
# Usage: ./scripts/verify.sh "file1.cs" "file2.cs" ...
#
# Why a clean build? An incremental build SKIPS recompiling unchanged projects, so a
# "0 Warning(s)" from an incremental build can be a lie (CS8601 slipped past this way on
# 2026-08-29). This script forces a full rebuild so the 0-warning claim is only ever made
# against fresh compiler output.
#
# Requires WINDOWS dotnet (never Linux dotnet — it re-downloads the windowsdesktop packs
# over the slow 9p bridge; see ai.md -> Run). Reads the Windows path from the WSL mount.
