+// Local patch for the Adventure Land game server (applied at image build time).
+//
+// The upstream DRM check in node/server.js (start_character) treats every
+// account created after 2019-02-01 as unverified unless it carries a Steam or
+// Mac App Store auth id. A self-hosted server cannot issue those ids (Steam
+// tickets need the game's private publisher key, and Steam OpenID sign-in needs
+// a publisher web API key), so every login gets the "authfail" condition:
+// gold/luck -85%, xp -20%.
+//
+// AL_DRM_CHECK=0 disables the check. Unset or any other value keeps the
+// upstream behaviour. The script fails loudly when the upstream line is gone,
+// so a code update cannot silently skip the patch.
