desktop_windows_release.yml

name: Auto Release Desktop (Windows) on Main

# Windows counterpart to desktop_auto_release.yml (macOS). Same SHAPE:
#   merge to main touching the desktop app -> bump the patch version, tag it,
#   build the installer, publish it to a prerelease (beta) GitHub Release.
#
# Difference from macOS: macOS only tags here and hands the build to Codemagic.
# Windows has no external CI, so this workflow ALSO builds + publishes, on a
# windows-latest runner, using electron-builder (NSIS) + gh.
#
# The git tag `v<version>-windows` is the source of truth for the version
# (mirrors macOS, where the tag — not a checked-in version field — drives
# releases). The version is stamped into package.json at build time from the
# tag; the same bump is synced back to main as a best-effort PR so the checked-in
# version tracks reality.
#
# electron-builder config: the build steps pass `--config electron-builder.config.mjs`
# explicitly. electron-builder only AUTO-detects electron-builder.<ext>; the
# `.config.mjs` name is NOT auto-detected, and that JS config is what computes the
# pi-mono asarUnpack closure at pack time. Dropping the flag would silently ship an
# installer missing that closure and break the coding agent. `pnpm build:win`
# already carries the flag; the signed path passes it by hand.
#
# Loop prevention (the bump must not re-trigger this workflow):
#   1. Every git write here uses GITHUB_TOKEN, and GitHub does not start new
#      workflow runs for pushes made with GITHUB_TOKEN. This alone breaks the loop.
#   2. Belt-and-suspenders: the plan job skips commits whose message is a release
#      bump, and skips when there is no releasable desktop/windows change since
#      the latest tag (so an empty/no-op push never cuts a release).
