Retired: verified empty delta

Exact head fb8498d79ea9e560b0286324e21d6f1c136beb06 is an ordinary descendant of protected develop@2949d30718752ea5915c7713ba227e8c19d9e5bf with zero changed files. The original performance proposal below is retained only as provenance and is not current repository behavior or evidence.

Original proposal (historical)

💡 What

scanner/cli/appguardrail.py 내의 _is_sensitive_rule와 _finding_category 함수에서 사용되던 any() + generator expression 형태의 문자열 포함 여부 검사를 명시적인 or 체인으로 변경했습니다. 또한, 데드 코드가 되는 _SENSITIVE_RULE_TOKENS 상수를 제거했습니다.

🎯 Why

Python에서 any()와 generator expression을 함께 사용하면 루프가 반복될 때마다 generator 객체가 생성되고 함수 호출 오버헤드가 발생하여 성능 저하를 일으킵니다. 특히 파일 스캐닝과 같은 핫루프(hot loop) 내에서는 이러한 오버헤드가 누적되어 전체적인 성능에 부정적인 영향을 미칩니다. 명시적인 or 체인을 사용하면 C 레벨에서 최적화된 short-circuit 평가를 통해 성능을 크게 향상시킬 수 있습니다.

📊 Impact

벤치마크 테스트 결과, 기존 any() 기반 검사(약 0.15초/10만회)에 비해 or 체인 방식(약 0.02~0.06초/10만회)이 최대 6배 이상 빠른 성능을 보여줍니다. 이는 스캐닝 과정에서의 문자열 매칭 처리 속도를 크게 개선합니다.

🔬 Measurement

변경 전후의 성능을 아래와 같이 테스트하여 검증했습니다.

# perf_test.py
import timeit

# 기존 방식
stmt1 = "any(token in lowered for token in tokens)"
# 최적화 방식
stmt2 = "('secret' in lowered or 'password' in lowered or ...)"

테스트 코드 실행 시 or 체인이 월등히 빠른 실행 속도를 나타냅니다.

Exact-head lifecycle correction — 2026-10-03

• Exact head: 1b02c80e76a992101e8c4b852128a6c0cb16ed10.
• Eight non-CodeQL workflows are terminal SUCCESS, but CodeQL run 37021368939 is terminal FAILURE; both compatibility verdict jobs failed and the dispatch job also failed.
• Qualifying APPROVED reviews: 0; unresolved threads: 0; the automated full review was rate-limited.
• The proposed optimization duplicates the security-sensitive token authority into long literal or chains without benchmark evidence, increasing maintenance drift risk relative to the existing single tuple.

The PR is preserved as Draft / Proposed pending a measured, single-authority repair and fresh exact-head evidence. No rerun, bypass, merge, release, or Close is performed.

Verified empty-delta retirement

• exact head: fb8498d79ea9e560b0286324e21d6f1c136beb06
• protected base: develop@2949d30718752ea5915c7713ba227e8c19d9e5bf
• ancestry: ahead 2 / behind 0
• effective changed files: 0
• GitHub PR metadata: changed_files 0, additions 0, deletions 0

The performance implementation has already been completely removed through ordinary ancestry. No source, test, documentation, dependency, or requirement delta remains to integrate or carry into a successor. The generated body still describes a nonexistent optimization and cannot serve as product evidence.

This retirement uses the explicit no-valid-delta exception. It does not discard a blocked, Proposed, or evidence-preserved change, and it does not claim that the zero-step failed workflows passed. No Force Push, destructive rebase, merge, or gate bypass was used.
