**Overall Verdict:** Strong Accept — The submission is complete, professionally realistic, securely evaluable, and demonstrably reachable end to end on the declared offline CPU environment.

**Completeness Check:**

- Instruction: Complete — The brief precisely defines target construction, publication-time constraints, DST handling, model architecture requirements, output schemas, runtime limits, and deliverables.
- Inputs: Complete — Realistic development data includes 154,944 quarter-hours, 14 PV regions, five disjoint wind parts, five weather locations, documented missingness, and a six-year holiday calendar.
- Toolchain: Complete — The offline Python/PyTorch stack, public simulator, package metadata, version constraints, and CPU-only execution path are specified and mutually compatible.
- Reference output: Complete — A full system, 92-day backtest, exported CNN/RNN/denoiser models, oracle training workflow, hidden truth, and an evaluator report passing all 28 checks are supplied.
- Rubric: Complete — All gates, stage weights, thresholds, tolerances, resource limits, probe behavior, scoring formulas, and partial-credit rules are machine-readable and implemented by the evaluator.

**File and Task Reachability:**

The attachment classification is `reachable`, and the end-to-end task classification is `reachable`. Both manifest attachments, `inputs.zip` and `reference_and_evaluation.zip`, were inspected. Their downloaded byte counts match the manifest; both are readable, unencrypted ZIP containers with valid compressed data, safe member names, no links or special files, and modest expansion sizes. The first contains 18 members and the second 244 members.

Inspection covered `TASK.md`, `DATA.md`, the task contract, examples, holiday data, all four development CSV schemas and representative records, simulator documentation and core source, environment metadata, the task card, evaluator and sandbox logic, protocol and formulation answers, hidden raw/truth/strata schemas, expert manifests and reports, the backtest manifest and metrics, one representative forecast NPZ, all three exported model containers and graph operators, and representative oracle training code. All JSON documents parsed successfully. The remaining 91 backtest NPZ payloads and individual model tensor values were inventoried and container-checked but not decoded value by value; uploaded code and models were not executed during review. Public-source and licensing claims are documented consistently but were not independently verified because external lookup is outside the evidence boundary.

The completion path is coherent: the contributor receives development data and the public simulator, builds the declared system and backtest, and the evaluator later stages protected reference material, verifies installation and output integrity, generates daily as-of packages, runs preparation under an unprivileged identity, executes exported models through evaluator-owned inference and DDPM code, runs leakage probes and target reconstruction, and scores against hidden truth. The reference report records 365/365 successful hidden days, exact grids and targets, passing accuracy/calibration thresholds, and a final score of 1.0. Hidden truth and oracle material are explicitly segregated and checked as unavailable before the contributor run.

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 strong instructions, authentic-looking operational data, reproducible reference evidence, and comprehensive evaluation isolation. No changes are required.
