**Overall Verdict:** Strong Accept — The submission is complete, professionally constructed, fully reachable, and supported by coherent inputs, reference artifacts, deterministic grading, and substantive difficulty evidence.

**Completeness Check:**
- Instruction: Complete — The authoritative brief is clear, internally consistent, and matches the declared SHA-256; it defines the estimand, analysis set, normalization, and exact six-file output contract.
- Inputs: Complete — All seven input archives match their declared sizes and authoritative checksums; they contain 129 expected files representing 80 libraries, with valid references, metadata, and 120 readable FASTQ files.
- Toolchain: Complete — A pinned, open-source Linux/CPU environment covers preprocessing, alignment, quantification, statistics, and grading without requiring a GPU or runtime network access.
- Reference output: Complete — All six required deliverables are present with matching schemas and coherent dimensions, including 1,004 analysis genes, 100 ranked genes, 40 assignments, and 80 QC rows; separate truth tables support objective evaluation.
- Rubric: Complete — Seven deterministic gates cover structure and key scientific failure modes, followed by an F1 threshold and defined partial-credit score; adversarial variants, baselines, and two documented self-tests substantiate discrimination.

**File and Task Reachability:**
Attachment classification: `reachable`. Task classification: `reachable`. I inspected `MANIFEST.txt`, `SHA256SUMS.txt`, all seven `input_part_*.tar.gz` archives, `reference_and_evaluation.tar.gz`, `difficulty_self_test_evidence.tar.gz`, and `difficulty_self_test_report.md`. Declared byte counts matched, the seven authoritative input checksums matched, archive paths and entry types were safe, all 120 inner FASTQ gzip streams validated, and representative records conformed to FASTQ structure and declared read layouts. The reference and self-test bundles were inventoried and their key instructions, schemas, truth tables, grader logic, trial reports, and representative records were inspected without executing submitted programs. No attachment was omitted; individual sequencing records were sampled rather than biologically interpreted exhaustively. Solver-visible inputs are separated from evaluator-only truth and grading assets. The completion path is practical on one CPU machine: unpack inputs, construct the pinned environment, preprocess and quantify the reads, infer assignments and purity, estimate gene slopes, write the six outputs, and apply the deterministic grader. 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. Public-reference provenance was not independently checked through search, but the inspected evidence provides no affirmative basis for a screening label; the simulated experiment is explicitly disclosed and is built around a professional genomics workflow rather than an AI-fabricated or defect-only fixture.

**Recommended Changes:**
The submission already provides unusually strong input validation, evaluator separation, adversarial gate testing, and measured difficulty evidence. No changes are required.
