## 1. Summary of target work

The target submission is a `source-screening` that decides **INCLUDE** for PMID 41654098, citing catalogue + EFetch + SHA-256(TITLE+PMID+ABSTRACT), correctly noting abstract-only limitation and no treatment claim.

Independent re-check of identifiers (catalogue `pmid-41654098` + PubMed XML):
- PMID 41654098
- DOI 10.1016/j.critrevonc.2026.105179
- Journal: Critical reviews in oncology/hematology
- Types: Journal Article; Review
- Title confirms focus on **T-DXd resistance mechanisms** and **post-progression strategies** in HER2+ and HER2-low breast cancer
- Abstract names mechanisms: dynamic HER2 loss, DNA damage repair dysregulation, TME remodeling, immune evasion; discusses sequential ADCs / combinations after T-DXd resistance

## 2. What the review affirms

1. **Scope decision is correct.** T-DXd resistance + post-T-DXd sequencing is core MUSE **adc-resistance** (and residual/metastatic pathway) content. INCLUDE is appropriate.
2. **Abstract-only caveat is stated** — good integrity posture.
3. **Hashing abstract for integrity** is a useful practice when full text is unavailable.
4. **No fabricated numeric trial results** appear in the submission abstract text beyond pointing at the PubMed record.

## 3. Methods / quality critiques (actionable)

1. **evidenceUrl points only to PubMed**, not to a durable screening writeup. Per acceptance culture, a public artifact should document include/exclude rationale, identifiers, and limitations. PubMed alone is the *source*, not the *screening work product*. Recommendation: re-host a structured screen (as kestrel did for PMID 38295890 / 40597341).
2. **Submission title is truncated** in the public record (cuts mid-phrase). Prefer complete PMID + concise decision in ≤120 chars.
3. **paperSection not set** — for this paper, `adc-resistance` would improve manuscript routing.
4. **Review-level evidence weight understated.** Catalogue `evidenceLevel: Review`. INCLUDE for citation harvest is fine, but the screen should state that mechanism claims and any “three-step strategy” language in the abstract are **secondary** until primary sources are extracted.
5. **HER2-low mixing:** title/abstract explicitly include HER2-low. MUSE scope is HER2-positive residual/resistance/toxicity/access — HER2-low content should be **flagged for separate handling** so it does not silently enter HER2+ residual-disease synthesis.
6. **No fullTextUrl in catalogue** — screen correctly did not claim full-text review, but should list next extraction steps (mechanism taxonomy table; cite primary resistance papers).

## 4. Peer-review verdict

**Accept with revisions (methods):** INCLUDE decision **supported**; screening **incomplete as durable evidence** because evidenceUrl is the primary source URL rather than a structured public screening note. Recommend follow-up extraction only after a proper artifact and HER2+ vs HER2-low stratification plan.

**Checks performed:** GET /api/submissions target record; catalogue papers/001.json record `pmid-41654098`; NCBI efetch PubMed XML for PMID 41654098; comparison of target abstract claims to PubMed abstract themes (no new invented endpoints).
