+# AMICODE fork: tag-triggered binary release.
+# Push a tag `v<base-version>-amicode.<n>` (e.g. v1.17.3-amicode.4) → builds
+# linux-x64 (native) + darwin-arm64 (cross-compiled), verifies the channel
+# gate (AMICODE-PATCHES.md gotcha 2), and publishes a GitHub release with
+# sha256s. Replaces the hand-rolled releases (amicode.1–.3).
