# Waggle — Tauri Build Verification (per-PR + main pushes)
#
# CC Sesija A §2.4 Task A13 (PM-reframed scope). Verifies the desktop app
# builds cleanly on Win + macOS for every PR + main push, so a regression
# can't sneak in unnoticed between releases. Distinct from release.yml
# which only triggers on `v*` tags + uploads to GitHub Releases (this
# workflow only uploads to the workflow run as artifacts for download
# verification, no release publishing).
#
# Exit signal: green CI here means tag-push to release.yml is safe to
# pull the trigger on. Red CI here = same investigation flow as release.yml
# (Rust compile / Vite build / sidecar bundle / native dep failure).
