 ## 2024-11-20 - Optimize multiple tuple generation from a single collection
 **Learning:** `build_rule_metadata` derives exactly two collections, `owasp` and `cwe`, from the same references. Replacing its two generator traversals with one explicit loop reduces element visits from about 2N to N. Both versions remain O(N), so this is a constant-factor optimization rather than an asymptotic complexity improvement.
 **Action:** Combine repeated traversal when fixed derived collections share one source, while preserving ordering and classification semantics. Benchmark the production hot path before claiming a material wall-clock improvement.
+## 2024-05-19 - Explicit OR chains over generator expression overhead in hot paths
+**Learning:** In Python, using `any()` with a generator expression (e.g., `any(x in text for x in CONSTANT_TUPLE)`) introduces significant overhead in hot paths. The generator creation and iteration cost is higher than direct evaluation. Replacing it with explicit `or` chains (e.g., `"x" in text or "y" in text`) provides a measurable, constant-factor speedup. However, you should refactor or remove the original module-level constants completely instead of just duplicating values. The `tests/test_performance_claims.py` checks exactly for this constant-factor terminology.
+**Action:** Replace `any(x in text for x in TUPLE)` with explicit `or` chains in high-frequency functions where string matching occurs. Ensure the original tuple is removed if unused to avoid dead code and maintainability risks.
