**Overall Verdict:** Strong Accept — The revised task is complete, professionally rigorous, objectively verifiable, and reachable without material implementation or evaluation risk.

**Completeness Check:**
- Instruction: Complete — The engineering objective, mechanics, drawing conventions, required models, reporting schema, naming, masses, degrees of freedom, and acceptance criteria are explicit.
- Inputs: Complete — Eight structured arrangement specifications and three readable, unencrypted engineering drawings provide the required topology, coordinates, radii, carrier data, rope paths, and haul rates.
- Toolchain: Complete — The CPU-only Python, MuJoCo, NumPy, and poppler-utils workflow uses legally obtainable open-source software and fits the declared single-machine environment.
- Reference output: Complete — Protected gold data, hidden drawing specifications, eleven reference MJCF models, passing and negative fixtures, and reproducibility sources cover every arrangement and deliverable.
- Rubric: Complete — Deterministic simulation checks, explicit tolerances, hard gates, variant scope, and detailed per-check failures distinguish complete, partial, and incorrect submissions despite binary aggregate scoring.

**File and Task Reachability:**
The attachment set is `reachable`, and the end-to-end task is `reachable`. Both manifest attachments were inspected: `reeving_mj_input_1.zip` and `reeving_mj_reference_1.zip`. Their downloaded sizes match the manifest; both are readable, unencrypted ZIP containers with bounded expansion, no duplicate or traversal paths, and no unsafe links or device entries. Inspected solver evidence included `problem_spec.md`, `output_contract.json`, all R01–R08 JSON specifications, and D1–D3 PDFs through metadata, extracted text, and visual rendering. Protected evidence included `gold.json`, `task_card.json`, R09–R11 hidden specifications, the reference and fixture model sets, fixture reports, documentation, revision notes, and evaluator/generator source. No manifest attachment was left unreviewed. Uploaded programs were inspected as source rather than executed under the safe-review boundary; independent static recomputation confirmed the published geometry, Jacobians, stroke offsets, velocities, fall counts, efficiency pulls, and verdicts. The completion path is direct: install the declared packages, construct eleven MJCF files and `results.json`, then let the deterministic grader load and measure each model for both variants. Solver-visible inputs are separated from protected gold, hidden specifications, and evaluator assets. 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:**
None

**Recommended Changes:**
The revision consistently publishes and grades the `main`/`aux` tendon names and the 50 kg travelling-block mass, resolving the prior contract drift. No changes are required.
