+Release hooks that need signing, notarization, or external publish credentials
+must read them from environment variables. The reusable release workflow passes
+declared caller secrets through to hook scripts, and the caller must include
+`secrets: inherit` or explicitly map those values. For macOS app releases this
+includes Dockyard-compatible variables such as
+`DOCKYARD_DEVELOPER_ID_APPLICATION`, `DOCKYARD_KEYCHAIN_ACCESS_GROUP`,
+`DOCKYARD_NOTARY_KEYCHAIN_PROFILE`, and optional Sparkle paths.
+
 Release policy:
 
 - create immutable exact tags such as `v1.2.3`
