current exact head aed3c117878371c9f8311bf82a45f17ba2c6c993에서 CWE-117 causal fix가 아직 닫히지 않았습니다.
path_str은 repr(path_str)로 neutralize되지만 error path는 logger.error("Failed to analyze audio %s: %s", repr(path_str), e)처럼 exception e를 그대로 %s로 기록합니다. Python logging의 deferred interpolation은 control character를 escape하는 보안 경계가 아니므로, exception message가 untrusted path/decoder metadata/외부 library payload를 포함해 \r/\n을 반환하면 같은 sink에서 forged physical log line을 만들 수 있습니다. CWE-117은 log sink에 쓰이는 모든 externally influenced field의 output neutralization이 핵심입니다.
RED: analyzer가 호출하는 boundary를 stub해 Exception("decoder failed\nINFO forged-entry")처럼 CR/LF가 포함된 실패를 발생시키고, 실제 configured formatter/handler가 만든 output에서 두 번째 physical record가 생기지 않는지 검증하십시오. path_str 자체의 CR/LF/ESC도 같은 test matrix에 넣고, 성공·실패 로그 모두 정상 message semantics를 보존해야 합니다.
GREEN: f-string→lazy interpolation은 성능/formatting 개선으로 유지해도 되지만 보안 조치는 sink-specific log-safe representation을 한 곳에서 소유하게 하십시오. path와 exception payload 모두 동일 neutralization contract를 거쳐야 하며, structured logging backend를 쓰는 경우에는 해당 encoder의 control-character contract를 테스트로 고정해야 합니다. 단순히 %s로 바꾸는 것은 security fix가 아닙니다.
또 현재 CRITICAL은 external attacker가 이 CLI/analysis path에 값을 공급하고 해당 log가 security-sensitive parser/viewer까지 도달한다는 배치·공격 경로가 evidence에 없습니다. 그 경로가 재현되지 않으면 severity는 defense-in-depth 수준으로 doctoring하십시오.
현재 판정: lazy logging PASS / path_str neutralization PASS 후보 / exception-field neutralization FAIL / hostile log-sink RED FAIL / CRITICAL severity evidence FAIL. BandScope dedicated writer lane이므로 fleet에서는 source를 직접 수정하지 않습니다.

Preservation / ownership status
This PR remains Open / Draft / mergeable and must not become an independent temporal/logging source owner.

The implementation remains weaker than #1055 because it preserves path/filename disclosure and overlaps the temporary CLI probe. Those source behaviors are not canonical.
Foreign-owner repairs
Earlier exact
c80c322d87113725db776b2c96b753c1b484847bcarried the unrelated Ruff-onlyservices/analysis-engine/tests/test_supply_chain_policy.pydelta. That file is canonical #1176 ownership and unrelated to temporal/logging semantics. Ordinary descendante05d051cb91a94b8ff77883b19f5c68813a9862brestored the protected-owner boundary.A later intervening commit
68e3f8dcca908002a8176c481206c354abbb7000reintroduced only that same formatter file (+1/-3) while leaving this lane's Temporal/security semantics unchanged. Ordinary descendanta993ac92a8f4729d68e54cf2a926c84eb5dad96brestores the exact repairede05d051c...tree while retaining the intervening commit in ancestry. Branch movement wasforce=false; current protected-base diff again excludestest_supply_chain_policy.py.Succession boundary
Canonical #1055 must ultimately absorb only still-valid evidence: attacker-shaped CR/LF source identity, decoder-exception control characters, and #1237's bounded caller-visible failure regressions, while keeping logs path-free, exception-text-free and the temporary CLI probe absent. #866 remains the active prerequisite before that source adoption.
Do not close merely because stronger lanes exist today. Unmerged closure is valid only after #1055 or a verified successor contains every valid test/fixture/contract/evidence delta, rejects the weaker path/filename/CLI behavior, obtains fresh exact-head gates plus qualifying independent review, and reaches protected ancestry.
No force-push, destructive rebase, copied #1176 source, self-approval, gate weakening, synthetic status, no-op freshness commit, blind rerun, or duplicate temporal ownership.
