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.

- Line 125: analyzer.py의 디코드 흐름과 transcription/api.py의 transcribe_bass_stem,

duration, sampling rate, channel count를 검증하고 메타데이터를 읽지 못하면 거부하십시오. duration 제한은
디코드 안전 한도로만 유지하고, 디코드 후 validate_decoded_audio 검증은 보존하십시오.

@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 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. Fresh live comparison establishes PR #866 (
fix(audio): establish canonical local-audio resource policy) onfix/audio-resource-policy-781as the current canonical Resource Admission & Decode owner. Keep new #781 implementation work on #866 unless a requirement cannot be safely absorbed there.This PR stays open and Draft only because it still contains behavior that must not be lost by title/number-based duplicate closure. In particular, its path-backed compressed-container metadata fallback (
soundfile.info(path)-> bounded localaudioread.audio_open(str(path))) preserves advertised M4A intake when libsndfile cannot inspect the container. That behavior changes the trust boundary from the already-open authorized descriptor to a filesystem path and may invoke an external decoder backend, so it must be transferred/reconstructed into the canonical Resource Admission & Decode port with explicit path/reparse/subprocess/resource evidence, or removed only after an explicit product/security decision changes the supported-format contract.Current exact identity:
develop@749511c3ad4000090048718f685c6bee6b3d2c25;071c1c84589397d565041f37515e39881718db98;3a76907dd3df603cc65188fa6d5c97d583f744e4.Predecessor or sibling checks, reviews, approvals, screenshots, and security evidence never transfer between heads or PRs.
Unique behavior / transfer contract
The reusable value on this branch includes:
rejection_reason,safe_message,policy_version) rather than a generic.reasoncompatibility surface;The first two items may overlap or conflict with #866's current public contract and must be reconciled semantically in the canonical owner rather than cherry-picked blindly. The M4A fallback is the known not-yet-superseded capability. Do not close this PR until the canonical owner demonstrably preserves or deliberately retires that behavior with executable evidence and a documented security/product decision.
#1129 commercial dependency boundary
This branch does not claim LGPL removal. Its runtime graph still includes
soundfile>=0.13.1andlibrosa>=0.11.0,audio_metadata.pyusessoundfile.info, the transitional decode port delegates tolibrosa.load, and this branch adds directaudioread==3.1.0plus lockfile changes. Issue #1129 remains the commercial-policy owner for removing the bundled/runtime libsndfile path from lock/build/package/SBOM/release inputs while preserving rights-safe real-audio behavior on Windows and macOS. Do not suppress native/SBOM inventory or treat process separation as a licensing waiver.Verification / closure gate
This branch is intentionally not merge-ready. Its latest head invalidates predecessor evidence, and current hosted gates are non-terminal. Queued, pending, skipped-required, cancelled, absent, neutral, failed, stale, predecessor-head, protected-base, model-only, status-only, or self-author evidence is non-passing.
Closure as superseded is allowed only after exact semantic diff proves every still-valid unique requirement/test/production behavior is present in #866 or its live successor, with technical succession evidence recorded. Until then, keep this branch Draft and avoid additional parallel feature expansion.
