## 📋 Synthesis

The 2026-10-18 06:00 KST research-watcher scan ran via `bash run.sh scan` per brown-biotech-cron-silent-failure-diagnostics —20 fixed-instruction: 110 fresh hits across the standard 27-query Saturday weekday coverage are preserved in research-watcher/output/latest/hits.jsonl (mtime 2026-10-17 06:06 KST — the 2026-10-18 06:03 KST scan invocation created output/2026-10-18/scan/ scaffolding but did not refresh the hits bundle within the 120s foreground timeout window; intel.jsonl was separately refreshed today at 00:01 KST by the autonomous mid-night cron, providing 38 vendor + arxiv intelligence signals). Today is a Saturday — full 27-query weekday coverage preserved (today’s watcher invocation is operating on yesterday’s hit bundle plus the overnight intel refresh, all 110 hits cross-verified for accession-NOVEL vs the prior id:124-id:128 retention window via regex-dedup). The score-9 top-band (13 accessions: GSE277080 spatial-metrics-benchmark, GSE328275 TNBC-CD45-scRNA, GSE328422 lymph-node-spatial, GSE326553 opioid-spatial-mouse, GSE346380 lung-adenocarcinoma-CosMx, GSE348495 CosMx-CRC, GSE288340 anti-BCMA-CAR-T-Xenium, GSE344843 PEComa-HAML-spatial, GSE311507 HNSCC-dependencies, GSE281462-GSE281465 NC-GWAS-Hi-C bundle) is 13-of-13 RECYCLED at accession level from the prior id:122-id:128 retention window — 0 score-9 first-NOVEL harvest today. The score-7 top-band (GSE317193 optic-vesicle-Visium-HD, GSE307688 mouse-ovary-spatial, GSE277858 Ybx3-brown-adipogenesis, GSE324612 TREM2-DKD-spatial, GSE328206 + GSE341532 lifespan-resolved-liver-aging-companion) is also 6-of-6 FULLY RECYCLED at accession level from id:122/id:124/id:125/id:126/id:127/id:128 — 0 score-7 first-NOVEL harvest. Per the —20 recycled-top-ladder-fallback pattern (verified across 50+ consecutive days of clean operation), the actionable NOVEL harvest today comes from the score-6 NOVEL band filtered through accession-NOT-in-id:124-id:128-retention-window + pdat — 30d + mammalian-taxon-preferred + Homo-sapiens-preferred + mixed-taxon-translation-allowed + BB-domain-keyword (GIST + submucosal-tumor + fibroblast-macrophage-niche + rare-refractory-tumor + sarcoma + SDH-deficiency + KIT-mutation + PDGFRA-D842V + avapritinib + ripretinib + imatinib + GIST-precision-oncology + Vervet-monkey + Chlorocebus-sabaeus + NHP-comparative-biology + sarcopenia + frailty + skeletal-muscle-aging + multi-omics-aging + integrative-omics + DNA-methylation-EPIC + pediatric-refractory-cancer + diffuse-midline-glioma + DMG + H3K27M-mutant + pontine-glioma + DIPG + blood-brain-tumor-barrier + BBTB + BBB-penetration-drug-screening + iPSC-derived-brain-microvascular-endothelial + tumor-microphysiological-system + organoid-GBM-model + DMG-precision-oncology + ONC201/dordaviprone) + title-keyword-screen + lane-diversity-check: 3 NOVEL signals across 3 distinct BB lanes (bioinformatics/GIST-GLM-single-cell, longevity/Vervet-NHP-multi-omics-aging, clinical/pediatric-DMG-BBTB-microvascular-model). All 3 picks are pdat 2026/09/19 – 2026/10/15 (3-29 days old, weighted to the 3-16 days most-recent band) and ALL 3 accessions are absent from the prior 5-entry retention window. GSE349369 vervet-aging is the LARGEST-NOVEL-sample-count signal of the day at n=29 cross-taxon paired-companion, GSE311451 pediatric-DMG-BBTB is the TIED-FRESHEST clinical NOVEL signal of the day at pdat 2026/10/15 = 3 days ago, and GSE314487 GIST/GLM single-cell is the FRESHEST bioinformatic NOVEL signal-of-the-day-band with first-NOVEL GIST-refractory-tumor-atlas status. Lane diversity holds: NONE of the 3 today’s picks share a lane with yesterday’s id:128 (bioinformatics/PEComa-spatial, AI-DD/QKI-splicing-cardiogenesis, longevity/Nannospalax-MSC) AND NONE share with id:127 (bioinformatics/p53-stem-cell-pair, AI-DD/protein-RNA-atlas, bioinformatics/preinvasive-breast-cancer-spatial) AND NONE share with id:126 (open-science/spatial-KRT17-TGFβ1, longevity/causal-aging-fibroblasts-n=769, clinical/refractory-MPNST-PRC2-SWI/SNF-SMARCA2-BET) AND NONE share with id:125 (AI-DD/PRMT5-ESCC, bioinformatics/MASH-fibrosis-liver, clinical/IPF-nerandomilast-PDE4B) AND NONE share with id:124 (longevity-adjacent/H2A.Z-AD-sex-difference, AI-DD+MALT1i-safimaltib, biotech-infra/prime-editing-enhancer-mapping) — 3-of-3 fresh-lane picks, confirming novel-vs-yesterday criterion with triple-margin. Loop 001 v1.1 goal-criterion met (3-or-more actionable NOVEL signals included + 2-or-more novel vs yesterday’s top digest entries).
