**Overall Verdict:** Strong Accept — The submission is complete, internally consistent, professionally scoped, objectively verifiable, and reachable end to end without material contributor-side gaps.

**Completeness Check:**

- Instruction: Complete — Exact DSP procedures, numerical tolerances, output structure, reporting requirements, and prohibited claims are unambiguous.
- Inputs: Complete — The deterministic PCM16 WAV, provenance, contracts, renderer, starter materials, dependency wheels, and integrity manifests are present and consistent.
- Toolchain: Complete — A hash-declared CPython 3.12 runtime, compatible offline NumPy and Pillow wheels, Linux sandbox runner, adapter, and licensing notices provide a viable toolchain.
- Reference output: Complete — The 17-file known-good output is substantive; arrays, WAV payloads, metrics, plots, report, and manifest reconcile with direct non-executing checks.
- Rubric: Complete — Twelve explicit binary gates cover input integrity, artifacts, numerical correctness, reporting, quality thresholds, and public and hidden replay.

**File and Task Reachability:**

Attachment classification: `reachable`. Task classification: `reachable`. Both `speech_audio_dsp_denoising_resampling_Input_Materials.zip` and `speech_audio_dsp_denoising_resampling_Reference_Output_and_Evaluation_Dependencies.zip` were fully inspected. Their 22-member and 131-member inventories are readable, unencrypted, non-traversing, and integrity-consistent. Review covered contracts, manifests, UTF-8 and JSON structure, WAV encoding, NPZ schemas and transformations, PNG dimensions and representative visual content, sanitized source pages, reports, evaluator source, dependency metadata, and nested runtime topology. No task-relevant attachment content remained unreviewed. Uploaded programs and binaries were inspected statically but not executed; clean replay was not independently run because evidence-review policy prohibits executing uploaded code and no independent compatible Python runtime was available. The completion path is clear: process the public WAV using the supplied contracts, generate the exact output tree, validate it through independent recomputation, then replay unchanged source against pristine public and hidden inputs under the bundled isolation path.

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 submission already provides unusually thorough contracts, integrity controls, reference evidence, hidden-challenge protection, and negative-test coverage. No changes are required.
