-#!/bin/bash
-#
-# Installs a launchd agent that keeps the Bazel server alive on a CI runner.
-#
-# The Bazel server holds the loaded/analyzed build graph in memory (the
-# "skyframe graph"). GitHub Actions kills orphan processes after each job,
-# which kills the server and forces a cold reload on every CI run (~15-20s).
-#
-# This script installs a launchd agent that periodically pings the server,
-# keeping it alive between jobs. Since launchd owns the process (not the
-# GitHub Actions runner), the orphan cleanup won't touch it.
-#
-# Usage:
-#   ./install-bazel-keepalive.sh <workspace-path>
-#
-# Example:
-#   ./install-bazel-keepalive.sh ~/github/actions-runner-macos-build/_work/eagle0/eagle0
-#
-# To uninstall:
-#   launchctl bootout gui/$(id -u) ~/Library/LaunchAgents/com.eagle0.bazel-keepalive.plist
-#   rm ~/Library/LaunchAgents/com.eagle0.bazel-keepalive.plist
