# Phase 4 (N-04): CI locks the regression floor — the lint/format/typecheck
# gates run on every push/PR, the full Electron battery on main pushes,
# nightly, and manual dispatch. Roadmap: "Gate on main; nightly full battery
# with artifacts on failure."
#
# Cost note: macos runners bill 10x Linux minutes, so the heavy battery does
# NOT run on PRs — gates do. A PR that needs the battery can only get it via
# a push to main or a manual dispatch (documented tradeoff, not an oversight).
#
# Environment risks (fix-forward, see log on red):
# - Electron smoke opens real BrowserWindows. macOS runners have a WindowServer
#   and this works for most Electron projects, but if suites fail with
#   display errors the fix is a headless flag in scripts/smoke-all.sh's
#   electron_run (e.g. --headless=new where supported), not deleting suites.
# - First battery run on a cold model cache downloads SigLIP weights (~370MB)
#   plus tesseract CDN data; the actions/cache below makes later runs fast.
