Performing `array.find()` inside loop bodies or filter predicates results in costly O(N*M) lookups. **Action:** Convert arrays to `Map` lookups before entering loops/nested scans. Mapping keys once in O(M) time enables O(1) lookups during execution, transforming the time complexity of the grading logic to O(N + M). + +## 2026-07-16 - [Transient Query Promise Caching in Rule Evaluators] +**Learning:** Evaluating multiple rules or criteria sequentially (such as checking badge conditions like completed lessons, tool sessions, and user metrics) can cause redundant database roundtrips for the same records or aggregates in a single request. +**Action:** Use a transient local cache class that stores and shares database query Promises during the request lifecycle.
