* **New Features** * Routes can promote route-local bypass rules into matching entrypoint middleware, layering route-specific bypasses onto existing entrypoint rules and avoiding duplicate evaluation. * **Behavior Changes** * Entrypoint middleware updates now refresh per-route overlays at runtime; overlay compilation failures result in HTTP 500 (errors are not exposed verbatim). * Route middleware accessors now return safe clones. * **Documentation** * Clarified promotion, consumption, merging and qualification semantics with examples. * **Tests** * Added tests covering promotion, cache invalidation, consumption semantics, and error handling. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
