 ## 2026-02-20 - [Optimized Telemetry Redaction and Sanitization]
 **Learning:** Sequential `re.sub` calls are faster than combined regex callbacks for small pattern sets, but the biggest performance win comes from early-exit fast-paths (e.g., checking for `\x1b` or secret keywords) and proper ordering of truncation vs. redaction for large strings.
 **Action:** Always implement fast-path guards for expensive string processing and ensure that heavy operations (like regex) are performed on the smallest possible data subset (e.g., after truncation).
+
+## 2026-02-21 - [Optimized Validation and Unit Test Gate]
+**Learning:** Replacing `re.sub(r"\s+", "", text)` with `"".join(text.split())` provides a ~6-9x speedup for whitespace removal in Python. Pre-compiling regex patterns and using simple keyword-based fast-path indicators (`_SECRET_INDICATORS`, `_DANGEROUS_INDICATORS`) can significantly reduce overhead when processing large, mostly-clean datasets.
+**Action:** Use built-in string methods over regex for simple character removals and implement keyword-based fast-paths to gate complex regex suites.
