+# v0.2.5 독립 리뷰 수정 증거
+
+**릴리스 차단.** ebur128/pyloudnorm loudness 조건은 통과했지만 동일 faster-whisper VAD gate가
+새 market WAV에서 1개 segment를 반환했다. `requiredEmptyPassed=false`이며 이를 `true`로 요구하는
+단위 테스트는 실패 상태다. 승인/commit/push/merge/tag/deploy는 하지 않았다.
+
+기존 상위 `.agent/evidence-v0.2.5`의 150개 파일은 [history-sha256.json](history-sha256.json)으로 고정했다.
+수정 전 bundle과 RESULT/정규화 계획은 `rejected-*` 사본으로 보존한다. 기존 loudnorm input_i의
+0.01 LU spread 주장은 전용 ebur128 2.0 LU / 독립 리뷰의 pyloudnorm 0.2.0 1.925 LU와 모순되어
+**거부된 역사 증거**다. 상위 GREEN 표시는 당시 테스트 결과이며 현재 릴리스 통과가 아니다.
+
+## TDD와 결과
+
+| 검사 | 증거 | 결과 |
+| --- | --- | --- |
+| 복원한 전용 ebur128 목표/동등성 | [01 RED](01-ebur128-RED.log), [06 GREEN](06-ebur128-GREEN.log) | 2.0 LU 실패 → 0.0 LU 통과 |
+| 순수 scalar/사전 peak/보정/비수렴 | [02 RED](02-linear-RED.log), [04 GREEN](04-linear-GREEN.log) | 7개 통과 |
+| exact 새 WAV ASR gate | [03 RED](03-asr-gate-RED.log), [08 실제 실행](08-asr.log), [결과](final-asr.json) | 실패 보존 |
+| 새 manifest의 빌드 계약 | [07 RED](07-build-contract-RED.log), [15 unit](15-unit.log) | 해당 39개 통과 |
+| 새 원자 생성 | [05](05-regenerate.log) | 8개 전체 교환 |
+| 전용 ebur128 독립 측정 | [스크립트](measure-ebur128.py), [결과](ebur128-results.json) | 전수 −32.5 LUFS, spread 0.0 LU, 최대 −6.2 dBTP |
+| 별도 pyloudnorm 독립 측정 | [스크립트](measure-pyloudnorm.py), [결과](pyloudnorm-results.json) | −32.6062~−32.5291 LUFS, spread 0.0771547792 LU |
+| Python 전체 | [11](11-python.log) | 47개 통과 |
+| lint/typecheck | [14](14-lint.log) | 통과 |
+| npm test | [15](15-unit.log) | 143 통과 / 1 실패 (ASR) |
+| build | [16](16-build.log) | 통과 |
+| audit | [JSON](npm-audit.json) | 취약점 0개 |
+| Chrome desktop/mobile | [17](17-browser.log), [summary](browser-summary.json) | 36 PASS, skipped/flaky/unexpected=0 |
+| 같은 원본에서 두 번 재생성 | [18](18-reproducibility.log), [JSON](reproducibility.json) | PCM/통계/notice 동일, generatedAtUtc만 제외 |
+| 역사/원본/음성/dist 보존 | [20](20-preservation.log), [JSON](preservation.json) | 통과 |
+
+현재 manifest의 hash는 ASR와 pyloudnorm 결과에 연결되어 있고 각 WAV hash도 기록되어 있다.
+ASR 모델 revision/모델 파일 hash/VAD hash/전체 기본 옵션/seed/의존성/스크립트 hash는
+[final-asr.json](final-asr.json)에 있다. 기존 실패·no-VAD는 수정하지 않았다.
+market의 exact SHA-256은 `7178307c48c192ac396dcd3c880c377bf56b45e829b459b1feca9f986437e632`이며,
+반환 구간 10.45–12.45초, 후보 텍스트 ` Let's go, let's go, let's go.`를 그대로 남겼다.
+이 텍스트는 검증된 전사가 아니다. humanListeningAcceptance/legalPrivacyClearance는 모두 false다.
+
+## 독립 pyloudnorm 재현
+
+일반 npm test는 이 가상 환경이나 네트워크를 사용하지 않는다. 아래 절차는 별도의 독립 증거 재현용이다.
+Python 3.11/Linux x86_64 wheel을 고정했다. [의존성 lock](pyloudnorm-requirements.lock)의 모든 버전과
+SHA-256을 사용한다. [wheel inventory](pyloudnorm-wheels.json), [설치 로그](09-pyloudnorm-install.log),
+[freeze](pyloudnorm-requirements.txt)를 함께 보존했다. pyloudnorm=0.2.0, soundfile=0.13.1,
+libsndfile=1.2.2; 나머지 패키지 버전과 Python 버전은 결과 JSON에 있다.
+
+기존 증거를 덮어쓰지 않도록 새 임시 디렉터리에 같은 상대 경로를 구성한다. 설치에는 네트워크가
+필요할 수 있지만 WAV 측정은 로컬 파일만 읽는다. `open('x')`가 기존 결과 덮어쓰기를 거부한다.
+
+```bash
+review_run=$(mktemp -d /tmp/findword-independent-XXXXXX)
+python3 -m venv "$review_run/venv"
+"$review_run/venv/bin/pip" install --require-hashes -r .agent/evidence-v0.2.5/review-fixes/pyloudnorm-requirements.lock
+mkdir -p "$review_run/public" "$review_run/.agent/evidence-v0.2.5/review-fixes"
+cp -a public/ambience "$review_run/public/ambience"
+cp .agent/evidence-v0.2.5/review-fixes/measure-pyloudnorm.py "$review_run/.agent/evidence-v0.2.5/review-fixes/"
+"$review_run/venv/bin/python" "$review_run/.agent/evidence-v0.2.5/review-fixes/measure-pyloudnorm.py"
+```
+
+동일한 임시 경로에 `measure-ebur128.py`도 복사해 `python3`로 실행하면 전용 FFmpeg 계기를 별도 재현할 수 있다.
+FFmpeg 6.1.1-3ubuntu5와 정확한 input bytes 범위에서 재현성을 검증했으며 다른 빌드의 byte 동일성을 보장하지 않는다.

+# Find-Word v0.2.5 구현·검증 결과
+
+작성일: 2026-10-14 UTC. 작업 경로: `/home/hermes/worktrees/find-word-v0.2.5`.
+브랜치: `fix/v0.2.5-ambience-loudness`. 기준/현재 HEAD:
+`812540c7438639f25b886cfd620201d92de15362` (변경 없음).
+
+## 결과와 인수 경계
+
+요청한 로컬 구현을 완료했다. 선언한 **FFmpeg 6.1.1 loudnorm 입력 측정** 기준으로 실제 8 WAV의
+integrated loudness는 **−38.69~−22.20 LUFS, spread 16.49 LU → −32.01~−32.00 LUFS,
+spread 0.01 LU**다. 고정 목표 **−32 LUFS**, 허용오차 ±0.2 LU, spread≤0.4 LU를 통과한다.
+최대 true peak는 **−6.62 dBTP**, 선언 ceiling **−6 dBTP** 이하다.
+런타임 배경 gain은 환경·현재 SNR·intro 유무에 무관한 **0.4198884518664126**이다.
+
+lint/typecheck, 139 unit/component/release tests, 40 Python tests, build, npm audit,
+sandboxed system Chrome desktop/mobile 36 tests를 통과했다. 이전 증거 660개와 voice WAV
+101개, 원본 8개·구간·creator·license·attribution을 보존했다. **commit/push/merge/tag/deploy는 하지 않았다.**
+
+인수 시 다음 두 제한을 반드시 함께 읽어야 한다.
+
+1. 별도 FFmpeg `ebur128=peak=true` 진단 계기는 최종 **−33.5~−31.5 LUFS, spread 2.0 LU**를 보고한다.
+   이 계기에서는 ±0.2/0.4 LU 조건을 통과하지 않는다. 계약 계기는 사용자 baseline 16.49 LU와 같은
+   `loudnorm input_i`로 명시했다. 독립 검증은 생성기/manifest 수치를 재사용하지 않고 실제 파일을
+   별도 프로세스로 분석한다는 뜻이며, 서로 다른 EBU 계기의 상호 일치를 뜻하지 않는다.
+2. 새 exact WAV의 추가 ASR 재검사는 **market 1 segment, requiredEmptyPassed=false**다.
+   이를 성공으로 바꾸거나 원본 구간/ASR 설정을 변경하지 않았다. 이전 Oz 승인은 exact v0.2.3 WAV에
+   한정되며 새 바이트의 승인으로 확대하지 않았다. **humanListeningAcceptance=false,
+   legalPrivacyClearance=false**이며 새 자산의 privacy/청취 인수와 릴리스 결정은 남아 있다.
+
+## 입력·출처·버전 보존
+
+- [.agent/TASK-v0.2.5.md](TASK-v0.2.5.md), [ACCEPTANCE-v0.2.5.md](ACCEPTANCE-v0.2.5.md)를
+  읽고 현재 코드/테스트/문서와 v0.2.3 결과·privacy/원자 발행 증거를 확인했다. 원본 task/checklist는 수정하지 않았다.
+- 원본은 `/tmp/findword-ambience-sources`의 8개 파일만 사용했다. 불변 선정 계획

+## 오프라인 생성과 최종 파일 독립 측정
+
+`scripts/ambience_audio.py`는 해시 검증 → 승인 구간 추출/mono/24kHz → 기존 50ms 양끝 선형 fade →
+2-pass loudnorm → PCM16 인코딩 → 최종 파일 재측정 → 전체 staging 검증 → 원자 발행 순서다.
+Ogg seek가 짧은 PCM을 반환하면 기존 full decode/sample trim fallback을 사용하며,
+padding이나 구간 변경으로 길이를 맞추지 않는다.
+
+공통 필터는 `loudnorm=I=-32:TP=-6.1:LRA=50:dual_mono=false:print_format=json`이다.
+목표 −32는 crest factor가 큰 market까지 선형 gain만으로 −6 dBTP ceiling을 지킬 수 있도록 정했다.
+필터 ceiling −6.1은 최종 ceiling −6보다 여유를 둔다. LRA=50은 원본 다이내믹을 압축하지 않기 위한
+허용 상한이며 최종 LRA를 50으로 만드는 목표가 아니다.
+
+pass1과 pass2에는 동일한 fade 적용 float PCM을 입력한다. pass2는 pass1의 measured_I/TP/LRA/thresh,
+`offset=0:linear=true`를 사용한다. 동적 1-pass 출력 예측의 `target_offset`은 선형 입력 gain 보정에
+사용하지 않는다. FFmpeg의 0 LRA sentinel은 전달 인자만 0.01로 올리고 원래 통계를 보존한다.
+실제 8개 입력은 모두 LRA>0이다. pass2가 dynamic으로 fallback하면 생성 실패로 처리한다.
+
+round(sample×32767)로 PCM16을 만들고 clipping clamp/dither 없이 범위를 검증한다. 각 파일은
+**288,000 frames, 정확히 12초, 24,000Hz, mono, PCM16, 576,044 bytes**, non-silent이고 고유 hash다.
+시작/마지막 sample은 0이며 50ms fade를 유지한다. 생성기는 최종 WAV를 새 FFmpeg 프로세스로
+읽고 `input_i/input_lra/input_tp`를 검사한다. 측정 필터의 `output_*`는 가상 재정규화 결과라서
+번들 측정값으로 사용하지 않는다. pass1/pass2/final 전체 JSON과 필터는 manifest에 보존한다.

+## 런타임 고정 gain과 fail-closed 경계
+
+이전 +6dB/luck-apple/intro 조건의 market 배경 gain은 **0.7259647911927253**,
+최종 RMS는 **0.021778943734156713**이었으며 다른 환경은 gain=1/RMS=.03이었다.
+기존 peak 의존 gain은 전체 비교에서도 1,084개 서로 다른 값을 만들어 문제를 재현했다.
+
+새 런타임은 배경 PCM을 그대로 복사하고, voice/intro만 기존 RMS **.03**으로 정규화한다.
+검증된 보수적 peak 상한은 **B=.55, V=.25, I=.20**, intro 최대 상대 gain은 **1.8**,
+허용 SNR_MAX는 **12dB**, master≤1에서 합성 ceiling은 **.8**이다.
+
+```text
+r_max = 10^(12/20) = 3.9810717055349722
+D = B + V*r_max + I*1.8 = 1.905267926383743
+G = min(1, 0.8/D) = 0.4198884518664126
+backgroundGain(db, environment, introPresent) = G
+voiceGain(db) = G*10^(db/20)
+introGain = G*1.8
+|mixedSample| ≤ master*G*(B + V*r_max + I*1.8) ≤ 0.8
+```
+
+삼각부등식으로 모든 위상/동시 overlap의 최악값까지 포함한다. 현재 파일의 실측 peak,
+환경, 현재 SNR, intro 유무는 G 계산에 들어가지 않는다. 배경 fade envelope는 기존과 같으며
+그 최대 gain만 G다. SNR은 voice의 기준 대비 gain 차이이지 실제 음성/배경 RMS 동등성을 뜻하지 않는다.
+UI 설명도 이에 맞게 수정했다. master와 intro fade, 3문항/단계/정답/점수/재청취 동작은 유지한다.
+
+실제 101 voice × 8 ambience × −12~+12의 모든 정수 25 SNR = **20,200개**를 검사했다.
+실측 최대 voice peak=.2052977830171585, intro=.14995422959327698, background=.45123291015625.
+이를 사용한 최악 합성 peak 상계는 **.6459797899491659 < .8**이며 배경 gain 집합의 크기는 1이다.

+Chrome에서 109 WAV를 24k/44.1k/48k/96kHz로 모두 디코드했다(프로젝트별 436개 측정).
+리샘플 후 최대 background=.466545045375824, voice=.20585650454525403, intro=.14999594059820148로
+모든 보수적 상한 이하다. 실제 장치 rate에서 상한을 넘는 파일은 gain을 낮추지 않고 재생을 거부한다.
+URL/bytes/SHA-256은 앱에 번들한 manifest를 기준으로 디코드 전에 확인한다. 외부/알 수 없는/이전 query,
+변조·축약 응답, 잘못된 채널/길이, nonfinite/무음/과도 peak는 fail closed한다. HTTP 200 WAV 한 sample
+변조도 실제 Chrome에서 소스 시작 전에 차단하고, 원본 재시도는 성공한다.
+
+실제 native Web Audio 메서드를 실행하면서 8환경 × SNR −12/0/+12의 GainNode를 프로젝트별 24회
+관찰했다. 예약 값은 모두 **.4198884518664126**, `AudioParam.value` 실측은 모두
+**.4198884665966034**(float32 반올림)다. 값에 맞춰 기다리지 않고 실제 AudioContext 시계가
+fade 종료 뒤에 도달했을 때 한 번 읽는다. master=1, voice/intro RMS .03, 같은 환경의 배경 RMS가
