Task classification: `reachable`. I inspected `baffle_fixture.pdf`, `baffle_fixture_reference.STEP`, `geometry_compare.py`, `score_submission.py`, `score_submission_partial.py`, `run.json`, and `eval_result.json`; fetched byte counts matched the manifest, formats matched declarations, and no required content was blocked or left unreviewed. The uploaded scripts were inspected as text and not executed. The PDF text layer contains no extractable text, but its rendered engineering drawing was visually inspected successfully. OpenCASCADE/Python execution was unavailable in the review environment, so STEP semantic execution and evaluator runtime behavior could not be independently rerun; this is a reviewer-tooling limitation, not a task defect. An ordinary solver can open the drawing, construct the model with the declared CAD toolchain, export `baffle_fixture.step`, and submit it to the strict scorer, which safely snapshots the file, parses the B-rep, aligns by translation and proper rotation, and checks solid validity, invariants, Boolean residuals, and bidirectional boundary distance. The partial scorer provides bounded non-additive credit for valid near-matches.\n\nLicense keys, accounts, tokens, and other credentials are not required from the contributor.  \nConfidential, proprietary, or internal material may be evaluated as submitted evidence without requiring additional disclosure.\n\n**Special Screening:**\nNone — no affirmative evidence supports AI-synthetic, public-benchmark, or synthetic-defect-fixture labeling. Public identifiability was not independently checked because this review was conducted without external search.\n\n**Recommended Changes:**\nThe submission is professionally specified and ready for use. No material changes are required.","reviewed_at":"2026-09-21T06:42:21.346273Z"},"claim":{"id":"58b70fb6-a4ca-4ee1-adcd-da5a2ce05fc7","submission_id":"3b0c82f5-a7fd-4d6c-a552-19b20b4c43d6","submission_revision_id":"bbd05bc9-1ff5-42f6-b65e-515be8d8bb80","builder":"builder-01","status":"active","claimed_at":"2026-10-15T15:30:50.430968Z","delivered_at":null,"ended_at":null,"delivery_note":null,"end_reason":null}},"revision_is_current":true}
