#!/usr/bin/env bash
# Run the blocking Windows gates (workspace build, production site) with real
# win-x64 Node.js under Wine — the same script the master-only `windows` job
# in ci-master.yml executes and the optional local gate `pnpm run check:windows-wine`
# wraps. Owning rationale and fidelity limits:
# .agents/notes/implemented/process/2026-08-08-native-windows-pull-request-ci.md
#
# The working tree is never mutated: tracked plus untracked-unignored files
# are snapshotted into a scratch directory, the Wine-specific pnpm overrides
# (hoisted layout, win32-x64 platform packages) are appended to the SNAPSHOT's
# pnpm-workspace.yaml, and the install and gates run there against the shared
# pnpm store. The Wine prefix and the checksum-verified Windows Node zip
# persist in .cache/wine-windows/ so reruns skip provisioning.
#
# Environment: DSH_WINE_NODE_MAJOR (default $PRIMARY_NODE_VERSION, then 24)
# picks the Windows Node line; DSH_WINE_GATE_CACHE_DIR relocates the cache;
# DSH_WINE_GATE_KEEP=1 preserves the scratch tree for inspection.
