Admit local and YouTube audio through one versioned 15-minute / 100 MiB / mono-stereo budget before decode or feature DSP. Rejection copy names the next song to choose and stays payload-free.

📝 WalkthroughWalkthrough버전 관리된 오디오 리소스 정책을 추가했습니다. 정책은 크기, 길이, 샘플레이트, 채널, 디코딩 샘플 수와 메모리를 검증합니다. 분석기와 YouTube 입력은 공통 검증 함수와 payload-free 오류 메시지를 사용합니다. Changes오디오 리소스 정책 적용
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The PR centralizes audio admission checks, but the current head can still decode inputs before validating original duration, sampling-rate, and channel metadata, while one path can sanitize invalid decoded samples before validation. This may admit malformed or resource-heavy audio and cause incorrect analysis, so merge should be blocked until the fail-closed paths are corrected. Sequence Diagram(s)sequenceDiagram

- Around line 24-30: Update the rejection-message list in the audio resource
policy documentation to include the exact decoded_sample_count_exceeded text,
“Choose a shorter song file to start analysis.”, in addition to the existing
shorter-or-smaller message. Keep the documented messages aligned exactly with
the canonical POLICY_MESSAGES entries.
In `@services/analysis-engine/src/bandscope_analysis/audio_resource_policy.py`:
- Around line 217-222: Update the audio validation guard in the policy-checking
function to reject any dtype whose kind is not in “fiu”, before calling
np.isfinite, while preserving existing malformed_header handling. Add tests
covering Unicode, byte-string, and datetime64 arrays and assert each raises
AudioResourcePolicyError.
In `@services/analysis-engine/src/bandscope_analysis/chords/chord_recognizer.py`:
- Around line 402-406: Update the empty-input guard in the chord recognition
flow to check whether the entire array has zero elements using y.size, so all
empty 2-D shapes return an empty list consistently before
validate_decoded_audio(y, sr) runs.
In
`@services/analysis-engine/src/bandscope_analysis/separation/audio_separator.py`:
- Around line 231-235: Update the stem-separation decode flow around
_as_float_array and validate_decoded_audio to validate the raw decoder output
for finite values before applying normalization that replaces NaN or Inf.
Preserve the empty-array check and return normalized audio only after
fail-closed validation succeeds.
In `@services/analysis-engine/src/bandscope_analysis/temporal/analyzer.py`:
- Line 125: analyzer.py의 디코드 흐름과 transcription/api.py의 transcribe_bass_stem,
separation/audio_separator.py에 librosa.load 전에 bounded metadata probe를 추가하여 원본
duration, sampling rate, channel count를 검증하고 메타데이터를 읽지 못하면 거부하십시오. duration 제한은
디코드 안전 한도로만 유지하고, 디코드 후 validate_decoded_audio 검증은 보존하십시오.
services/analysis-engine/tests/test_transcription.py 73-76에는 15분 초과 입력이
librosa.load 전에 거부되는 테스트를 추가하십시오.
In `@services/analysis-engine/src/bandscope_analysis/youtube.py`:
- Around line 175-186: youtube.py의 175-186행 블록과 147-157행 블록에서
AudioResourcePolicyError의 고정된 code를 error.reason으로 반환하도록 변경하십시오. 147-157행에서는 if
duration 조건을 if duration is not None으로 바꿔 0 길이 메타데이터도 검증하게 하십시오. 공개 오류 코드 계약 변경에
맞춰 services/analysis-engine/tests/test_youtube.py와 데스크톱 소비자의 오류 코드 매핑도 갱신하십시오.
In `@services/analysis-engine/tests/test_audio_resource_policy.py`:
- Around line 30-32: Update the return annotation of _policy_error from
pytest.RaisesContext to pytest.RaisesExc, keeping the existing
AudioResourcePolicyError type parameter and pytest.raises call unchanged.

@opencode-agent Continue repair on the existing Verify each review finding against the exact current head before changing it, then repair only still-valid BandScope-owned defects with TDD:
Run focused tests plus repository-pinned Ruff/Bandit and canonical quickcheck. Do not touch or suppress inherited npm dependency findings (#783-owned), do not change foreign repositories, and do not resolve unrelated threads. Commit on this same branch and report the resulting exact head and evidence. |

Ownership correction for the exact current lane: stop further source mutation on Do not execute the prior repair request in comment |

Ownership freeze after fresh exact-head review. Current #985 head is Do not continue parallel production writes on #985. Preserve this branch as reference evidence until its unique, still-valid work is reconstructed on #866 rather than merged/cherry-picked wholesale. The current unique evidence worth preserving is source-container preflight before transform/truncation, chord zero-element shape handling, transcription/chord policy coverage, and any reason-code regressions that remain compatible with #866's published error contract. Fresh #985 CI also proves this is not ready independently: run #866 already has an exact-head owner-control handoff to port the unique #985 evidence with RED→GREEN tests. Keep #985 unmerged and non-authoritative until that preservation is verified; close it only after exact semantic comparison proves no unique required behavior remains. |

#781 preservation / succession lane
This PR is not the canonical #781 writer. Canonical Resource Admission & Decode is Draft #866
fix/audio-resource-policy-781@cb9ffb4498d7d9237601e6dad6257ebb1da51e50on protecteddevelop@314ddeae7b775a4957594b599358c8255617eb2e. New #781 implementation belongs on #866 unless a still-valid requirement cannot be safely absorbed there.This PR remains open/Draft because one material capability is not yet demonstrated as superseded: its compressed-container metadata fallback (
soundfile.info(path)→ bounded localaudioread.audio_open(str(path))) attempts to preserve advertised M4A intake when libsndfile cannot inspect a container. That changes authority from an already-open admitted descriptor to a filesystem path and may invoke external decoder backends, so it must not be cherry-picked blindly.Succession decision boundary
#866 owns the stronger local-file foundation: app-owned same-project publication, bounded staging receipt, SHA-256 content identity and production re-verification before bootstrap authority; 100 MiB resource policy; YouTube admission/cleanup; path-free publication identity; bounded helper output; monotonic deadline; and one GUI-independent Linux/macOS process owner for analysis and timed YouTube import.
Current #866 also treats persisted separated-stem cache identity as untrusted rehearsal evidence. In addition to canonical
vocals/bass/drums/otheradmission and synchronized stem timelines, current replay now rejects a metadata sidecar that is replaced between the first metadata read and the archive owner's second read with a differentstemKeysidentity.

Full metadata↔NPZ↔admitted-source immutable generation/digest binding remains upstream #866 work.Current
cb9ffb449…verification remains #866's own gate; predecessor evidence does not transfer. Windows Job Object containment and whole-process rights-cleared real-audio resource measurement remain later #866 work.The remaining M4A fallback intersects commercial decoder defect #1129.
audioreaditself does not make an external decoder backend commercially acceptable, and #1129 requires removal of the libsndfile-backed LGPL runtime from actual lock/build/package/SBOM/release inputs with equivalent Windows/macOS real-audio behavior including advertised M4A/AAC support. Therefore the fallback remains requirement/evidence, not a mutable #866 dependency, until its concrete decoder backend, subprocess/path/reparse/resource authority and license provenance satisfy the commercial policy.Closure as superseded is allowed only after exact semantic evidence shows either (a) #866/current successor preserves supported M4A behavior through an approved decoder boundary with equivalent tests/rights-cleared real-audio evidence, or (b) an explicit product/security decision changes the supported-format contract and updates all buyer-facing/analysis contracts consistently. Until then do not close this PR merely because its other resource-policy behavior overlaps #866.
Current identity / gate
Preservation source remains exact
071c1c84589397d565041f37515e39881718db98, open/Draft. Its source ancestry is intentionally not rewritten onto mutable #866. Protected-base formatter repair remains #1176 ownership and central CodeQL/protection migration remains control-plane ownership. Do not expand this branch with parallel Resource Admission/process work, copy current #866 tests/fixes, self-approve, bypass, force-push, weaken gates or treat process separation as a licensing waiver.
