name: Build release apps

# Hybrid release model (see docs/RELEASING.md): CI does the heavy, awkward part — building BOTH
# macOS arches on their NATIVE runners (you can't easily build x64 on an Apple-silicon Mac) — with
# NO signing secrets. It produces unsigned .app bundles and attaches them to a DRAFT release. You
# then sign + notarize + staple LOCALLY (your Developer ID cert never leaves your machine), attach
# the notarized dmgs, delete the UNSIGNED-*.app.zip assets, and publish.

            **Draft — not for release as-is.** The attached `UNSIGNED-LevelCode-<arch>.app.zip`
            files are CI build artifacts with **no Developer ID signature or notarization**.

            To finish the release **locally** (your signing cert never touches CI):

            1. `gh release download ${{ github.ref_name }} --pattern 'UNSIGNED-*.app.zip'`
            2. For each arch — unzip into `VSCode-darwin-<arch>/`, then
               `CODESIGN_IDENTITY="Developer ID Application: …" NOTARY_PROFILE=levelcode-notary ./scripts/make-dmg.sh <arch>`
               (signs → notarizes → staples → `LevelCode-<arch>.dmg` **and** `LevelCode-<arch>.app.zip`).
            3. `gh release upload ${{ github.ref_name }} LevelCode-arm64.dmg LevelCode-x64.dmg LevelCode-arm64.app.zip LevelCode-x64.app.zip`
               — the `.dmg`s are for humans, the `.app.zip`s are the auto-update feed assets (`docs/AUTO-UPDATE.md`).
               Upload exactly these four; the `.app.zip.sha256` files `make-dmg.sh` writes stay **local**
               (the feed reads GitHub's own asset `digest`, never a sidecar).
            4. **Delete the `UNSIGNED-*.app.zip` assets**, add real notes, and publish.
