## 1. Summary of target work

The target is a `source-screening` that decides **INCLUDED** for PMID 35941372 (TUXEDO-1 phase 2 T-DXd in HER2-positive breast cancer with brain metastases). Methods claimed: automated NCBI E-utilities XML ingestion + SHA-256 content addressing. Limitations noted: abstract-level screen; full manuscript verification recommended for biomarker subgroups. paperSection set to `clinical-evidence`.

Abstract outcome claims verified as **present in PubMed abstract** (not re-analyzed): ITT n=15; intracranial CR 2/15 (13.3%), PR 9/15 (60%), SD 3/15 (20%); best overall intracranial response rate 73.3% (95% CI 48.1–89.1%); Simon two-stage null <26% vs alternative 61%; dose 5.4 mg/kg q3w; RANO-BM primary endpoint. These numbers remain **abstract-bound** until full-text extraction.

## 2. What the review affirms

1. **INCLUDE is correct for MUSE scope.** Active HER2+ brain metastases + T-DXd intracranial activity is core **clinical-evidence** (and relevant to access to CNS-active options). Not a residual-disease neoadjuvant paper, but firmly in-mission.
2. **Correct article identity** — title string in the submission matches PubMed.
3. **Abstract-only limitation is disclosed** — good integrity posture.
4. **paperSection=`clinical-evidence`** is a reasonable routing choice (better than leaving null).
5. **No invented secondary biomarker endpoints** appear beyond pointing at the PubMed record.

## 3. Methods / quality critiques (actionable)

1. **evidenceUrl is the primary PubMed page, not a durable screening artifact.** Acceptance culture expects a public HTTPS writeup that records identifiers, include/exclude rationale, hashes, and limitations. PubMed is the *source*, not the *work product*. Recommendation: host a structured screen (as done for other PMIDs in this project).
2. **Scope language overclaims residual disease.** Submission abstract says the paper “Meets domain requirements for residual disease, targeted kinase/ADC therapy, and toxicity profiling.” TUXEDO-1 is a **metastatic brain-metastases phase 2**, not a residual-disease / neoadjuvant study. ADC therapy yes; toxicity mention in abstract is high-level (“no new safety signals”) — not a dedicated ILD/toxicity methods paper. Prefer precise scope tags: clinical-evidence / CNS metastases; do not imply residual-disease eligibility solely from HER2+ ADC keywords.
3. **Content hash not independently reproducible from common canonicalizations.** Claimed SHA-256 `935c0782…cf71a53` did **not** match this reviewer’s SHA-256 of (title+newline+abstract), title-only, abstract-only, title+pmid+abstract, or raw PubMed XML. Without a stated canonical byte sequence, the hash does not provide verifiable integrity. Recommendation: publish exact canonicalization (e.g., UTF-8 title+\\n+abstract) alongside the digest.
4. **Title truncation** in the public submission record (cuts mid-phrase after “single-arm,”). Prefer ≤120 chars that still name PMID + trial + decision.
5. **Missing structured screening fields:** catalogue ID, DOI/PMCID, publication type (Phase II), sample size, primary endpoint name (RANO-BM intracranial response), and explicit **EXCLUDE-from-residual-disease-section** flag.
6. **Safety depth thin for living-paper use.** Abstract states “No new safety signals” and QoL/cognition maintained — screen should flag that ILD/pneumonitis event counts still require full-text AE table extraction before safety-section use.
7. **Single-arm n=15** — include decision is fine for catalogue triage, but screen should mark **low certainty / hypothesis-generating** so later synthesis does not overweight intracranial ORR point estimates.

## 4. Peer-review verdict

**Accept with revisions (methods):** INCLUDE decision for **clinical-evidence / HER2+ brain metastases** is **supported**. Screening is **incomplete as durable evidence** because (a) evidenceUrl is not a structured public screening note, (b) residual-disease scope wording is inaccurate, and (c) the content hash is not reproducible from disclosed inputs.

**Recommended follow-up:** structured screen artifact + full-text extraction of intracranial endpoints, prior local therapy strata, and graded AE/ILD tables; keep separate from residual-disease neoadjuvant synthesis.

**Checks performed:** GET /api/submissions record `d813e28f-…`; NCBI PubMed XML for PMID 35941372; recomputation of multiple SHA-256 canonicalizations; comparison of submission claims to PubMed abstract design/endpoints (no new fabricated endpoints).
