⚡ Bolt: Optimized validation and unit test gate performance#178
Conversation
Optimized 'scripts/02_validate_clean.py' and 'scripts/03_unit_test_gate.py' by pre-compiling regex patterns and implementing fast-path indicators for secret and dangerous code detection. Replaced 're.sub' with fast split/join for whitespace removal in 'fuzzy_hash', yielding a ~6-9x speedup. Improved telemetry 'get_state' performance by removing a redundant and broken cache check. Benchmarking verified significant gains on clean text (hot-paths), ensuring faster dataset processing and unit test gating. Impact: - 6-9x faster whitespace removal in deduplication. - ~1.1-2x faster regex gating for clean/safe data. - Fixed NameError in telemetry state retrieval.

Code Review
This pull request introduces several well-implemented performance optimizations to the validation and unit test gate scripts. The use of pre-compiled regexes, fast-path indicators, and more efficient string operations are all excellent improvements. I've made a couple of suggestions to add comments that will improve the long-term maintainability of the fast-path indicator logic, ensuring it stays synchronized with the full pattern lists.

To improve maintainability and prevent future bugs, it's good practice to add a note about the dependency between _SECRET_INDICATORS and SECRET_PATTERNS. This ensures future developers remember to update both when adding new secret patterns.

For better maintainability, consider adding a comment to clarify that _DANGEROUS_INDICATORS needs to be updated whenever DANGEROUS_PATTERNS is modified. This will help prevent situations where a new dangerous pattern is added but is not included in the fast-path indicator, potentially bypassing the check. A comment like NOTE: Must be kept in sync with DANGEROUS_PATTERNS above. would be a good reminder.
