**Issue Evaluation** Category: `type/enhancement` | Status: **Evaluated** **Feasibility:** feasible **Scope:** `AbstractLiteLifecycleManager`, `LiteEventDispatcher`, lite subscription model **Compatibility:** No protocol or external API change (internal refactor only) This is a well-motivated performance optimization. The proposed `LmqPrefixIndex` approach correctly targets the O(total lmqs) → O(matched lmqs) improvement for wildcard dispatch and lifecycle queries. The design is sound: - Prefix-ordered index populated at startup + maintained via lifecycle hooks is the right tradeoff (in-memory, no persistent index overhead) - Collect-then-delete for cleanup avoids lock nesting — good attention to concurrency - Subscription model simplification (`SubscriberWrapper` → plain Map) is a nice cleanup alongside the perf fix The issue is well-specified with clear alternatives considered. Unit test coverage for the index and rewritten paths is mentioned, which is good. **Recommendation:** This looks ready for implementation. The scope is well-contained and the risk is low (internal refactor, no API changes). --- *Automated evaluation by github-manager-bot* -- This is an automated message from the Apache Git Service.
