notes: "EXTREME TDD implementation with Toyota Way transparency. Features are 81.8% complete (9/11 tests) with comprehensive documentation of limitations. Property testing verifies invariants across 700+ generated cases. Mutation testing identified coverage gaps (21.7% vs 90% target) which are documented as Issue #3 and accepted for this release. This demonstrates Toyota Way principle: transparent documentation of limitations is better than shipping broken features."

notes: "Cleanup work revealed 3 defects, 2 of which were caused by SEC010 rule being too strict for test scenarios. Both tests now pass. The root cause was that 'rm $variable' triggers path traversal ERROR (exit code 2) instead of SC2086 WARNING (exit code 1). Fixed by using 'echo $variable' in tests. Also discovered .gitignore misconfiguration preventing test files from being tracked. Cloudflare-class logic bug found in taint.rs (|| true made condition always true). CRITICAL: Discovered DEFECT #5 (P0) - non-deterministic purification (permission check duplication on second pass). RESOLVED same session with EXTREME TDD fix (commit 6ebe03c80)."
