 ## 2024-05-19 - Pre-compile Regex Patterns in Loop-called Functions
 **Learning:** In `scripts/ci/pr_review_merge_scheduler.py`, the `scrub_sensitive_data` function was repeatedly compiling multiple regex patterns via `re.sub` for every log line or text scrubbed. This incurs measurable overhead due to cache lookups and object recreation in tightly looped string processing.
 **Action:** When using multiple regex replacements inside functions that are called frequently or process large amounts of text, define and pre-compile the regex objects at the module level (e.g., `SENSITIVE_DATA_SCRUB_PATTERNS`) and iterate over them using `pattern.sub()`.
+## 2026-06-27 - Pre-compile Regex Patterns in Text Scrubbing and Parsing
+**Learning:** In `scripts/ci/noema_review_gate.py` and `scripts/ci/opencode_review_normalize_output.py`, functions called in loops or performing repetitive regex substitutions (like `scrub_sensitive_data` and list item parsing in `changed_files_from_evidence`) were redundantly calling `re.sub` with raw strings. This causes repeated internal regex compilation or cache lookups, adding measurable overhead (up to ~10-40% in microbenchmarks).
+**Action:** Lift `re.sub` regex strings into module-level compiled objects using `re.compile()` (e.g., `SENSITIVE_DATA_SCRUB_PATTERNS`, `LIST_ITEM_PREFIX_PATTERN`), and use `pattern.sub()` within the functions to improve execution speed.
