**Overall Verdict:** Accept — The task provides coherent calibration inputs, a fixed simulation contract, and objective scoring, with explicit safeguards for publicly retrievable held-out measurements.

**Completeness Check:**

- Instruction: Complete — Defines the shared calibration parameters, required deliverables, prediction interval, and prohibited corrections.
- Inputs: Complete — Numeric arrays contain 60 public dynamic frames, 420 quasi-static frames, and complete 500 Hz controls; dimensions, units, frame IDs, and alignment limits are documented.
- Toolchain: Complete — Pinned dependencies, canonical simulator, and a provisioning template provide a reproducible workflow; runtime compatibility and performance were not independently verified.
- Reference output: Complete — Required artifact names and trajectory schemas are defined. Separate reference arrays contain exactly the 70 withheld dynamic frames, IDs 60–129.
- Rubric: Complete — Supplied scoring code matches the deterministic surface sampling, equally weighted frame statistics, thresholds, and 60/40 credit formula.

**File and Task Reachability:**

Attachments: `partially_reachable`, solely because the optional video preview was inspected structurally but not visually decoded. Task: `reachable` through the documented provisioned, offline workflow.

Inspected all six attachments: `agent_input.zip`, `Dockerfile`, `PREREQUISITES.md`, `verify_container.py`, `score.py`, and `ground_truth.npz`. The input archive’s 14 members were inspected, including documentation, scripts, JSON contracts, numeric containers, preview metadata, and checksum list. Downloaded sizes match the manifest; archive integrity checks passed, with no unsafe paths, encrypted entries, or excessive expansion. Numeric arrays have consistent schemas and no nonfinite values. Held-out frames are absent from the public input package.

The completion path is calibration against public observations, generation of the required artifacts, and a trusted canonical rerun against isolated references. Uploaded code was not executed. Simulation runtime, attainable accuracy, actual isolation enforcement, and external provenance were not independently verified.

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 submission explicitly identifies the source benchmark and states that withheld recordings are publicly retrievable. Mandatory offline execution, evaluator-asset isolation, and exclusion of external retrieval tools address runtime answer retrieval. No affirmative evidence establishes a memorized canonical fitted solution; external public facts were not independently checked.

**Recommended Changes:**

The data split, fixed physics contract, scoring implementation, and isolation requirements are well specified. No contributor changes are required. Before reporting any candidate score, the evaluator must enforce and verify the documented isolation requirements; the supplied template alone does not certify a valid evaluation environment.
