**Overall Verdict:** Accept — The submitted revision is complete, professionally representative, and reachable, with coherent grading and no material contributor-side gaps identified.

**Completeness Check:**

- Instruction: Complete — Required score content, historical spelling, output artifacts, and optional markings are clearly distinguished.
- Inputs: Complete — The readable three-page color scan contains the stated song and notation.
- Toolchain: Complete — The free MuseScore workflow and evaluator dependencies are specified; the offline, single-machine task fits the stated runtime budget.
- Reference output: Complete — The corrected MusicXML and native fixture independently agree on all 1,406 pitched note entries and 175 lyric syllables across three staves and 79 measures.
- Rubric: Complete — Explicit binary gates cover structure, notes, lyrics, historical spelling, clefs, metadata, 8va, and native/export consistency. Static inspection supports the reported regression coverage.

**File and Task Reachability:**

Attachments: reachable. Task: reachable.

Inspected `score_scan.pdf` and `lieder_scan_engraving_1_reference_and_grader.zip`, including the reference MusicXML, original MXL, native MSCZ fixture, grader, tests, task card, verification documents, and self-test materials. Declared byte counts matched; archive integrity checks passed, and nested containers and structured content were readable without encryption or unsafe paths.

Completion proceeds from scan transcription in MuseScore to native-score saving and MusicXML export, followed by evaluator-only comparison. References are explicitly separated from solver-visible inputs. No relevant attachment remained inaccessible. Uploaded programs were inspected without execution; the grader tests and MuseScore 4.7.5 workflow were not independently run. The blind self-test predates the native-file requirement and does not establish current end-to-end execution.

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` — The protected solution is explicitly identified as an existing OpenScore Lieder transcription. Hidden evaluator assets and disabled solver networking mitigate runtime retrieval. External availability and licensing claims were not independently verified; no evidence establishes canonical-benchmark memorization risk.

**Recommended Changes:**

The corrected reference, exact native/export content comparison, historical-spelling checks, and documented treatment of print ambiguities are substantive improvements. No contributor changes are required.
