**Overall Verdict:** Accept — The revision provides a coherent, technically reachable reconstruction workflow and objective standalone evaluation, with calibration and provenance limitations explicitly disclosed.

**Completeness Check:**

- Instruction: Complete — Defines all three movements, five roles, editable native reconstruction, continuous exports, routing constraints, and required evidence.
- Inputs: Complete — The full recording is readable, contains 47,282,976 frames, and has the specified four-second silent gaps. Solver materials contain no aligned-note answers.
- Toolchain: Complete — Native software, acquisition paths, licensing terms, automation interfaces, and reproduction procedures are documented. REAPER is proprietary evaluation software, despite the submission’s “Free/Open Source” field.
- Reference output: Complete — Includes the native project, MIDI, master, five stems, screenshot, and QC note. Independently parsed reference MIDI contains 20,965 balanced notes matching the packaged annotations within serialization precision.
- Rubric: Complete — Publishes weights, tolerances, partial credit, consistency gates, and infrastructure-error handling. Constructed dynamics and uncalibrated tonal thresholds limit interpretation as professional musical assessment.

Inspected all seven attachments: `music_evaluator_truth_20261010_v7.zip`, `music_standalone_scorer_20261010_v7.zip`, `music_input_and_software_20261010_v7.zip`, `music_independent_review_evidence_20261010_v7.zip`, `music_reference_outputs_20261010_v7.zip`, `music_model_trial_evidence_20261009_v7.zip`, and `music_ale_submission_20261010_v7_licenses.zip`.

All archive inventories were readable, with no detected traversal entries, unsafe links, encryption, or duplicate member names. Content inspection covered instructions, schemas, evaluator source, annotations, native projects, MIDI, screenshots, licensing records, execution evidence, full source audio, and rendered-audio headers. Selected reference files match the supplied integrity hashes. Bulk rendered waveforms and most model trajectory records were not inspected in full.

The completion path is viable on one suitable machine: analyze the supplied audio, author editable MIDI in REAPER, render the continuous master and stems, then evaluate against isolated hidden references. Archived evidence reports successful full-reference replay in approximately 42 seconds and complete reference scoring. Later revision-bound evidence reports an unchanged-candidate regrade of approximately 0.345, superseding the historical failed-audit summary; it does not establish a fresh final-prompt trial.

No submitted code was executed or native replay independently repeated during this review. External provenance was assessed from supplied records, not independently searched. Recording-specific rights confirmation and professional musical calibration remain disclosed uncertainties, not demonstrated violations.

License keys, accounts, tokens, and other credentials are not required from the contributor.

Confidential, proprietary, or internal material may be evaluated as submitted evidence without requiring additional disclosure.

**Special Screening:**

`public_benchmark` — Supplied primary-release metadata explicitly identifies MusicNet as a transcription benchmark, and this task reuses identifiable recordings and their aligned labels. Solver-visible answer separation and the offline workstation mitigate runtime answer retrieval. Prior model exposure or memorization was not established.

**Recommended Changes:**

The complete delivery package, explicit partial-credit contract, and revision-bound control evidence support acceptance. No material task revisions are required. Preserve the offline boundary, third-party notices, and stated limits on professional validation and difficulty claims.
