Provisional compartment-aware CTA candidate set
463 selected groups (481 loci), 17,388 Unsafe and 2,012 Neither across the complete 19,863-group reference. There are 120 new admissions and 0 lost selections relative to the previous 343-group funnel.
This is a deliberately more permissive research prioritization policy, not a clinically validated safety model. PRAME informed the parameter choice and is therefore a calibration example, not independent validation. No gene name or clinical product bypasses the rules.
Uniform rules
Reproductive/embryonic association, tumor ≥2 TPM/pTPM in one sample, required RNA coverage, Medium/High HPA protein findings, validated external protein findings and clinical-safety exclusions retain their existing rules. DICE and corneal coverage remain optional; measured findings still count.
Missing/unusable-IHC RNA ceilings are Vital 4, Protected 8, Manageable 16, specified renewing large-bowel epithelium 32. Each negative-IHC confidence step doubles its row. The stronger RNA boundary is twice the candidate ceiling. Assays retain native units and support guards; CP10K uses the existing nominal /100 policy, not a TPM conversion.
Mapped adult HPA fibroblasts use Manageable. Colon/rectum distal enterocytes, intestinal goblet cells, Paneth cells and undifferentiated cells use the renewing-mucosa row. Other cells keep their anatomical tier. Undifferentiated cells retain a stem/progenitor caution: their admission is an explicit tolerance assumption, not evidence that the regenerative compartment is disposable. Cardiomyocytes, endothelial cells and airway basal cells receive no such relaxation. Bulk retains its organ tier.
Explicitly Low normal HPA staining or an Accepted literature finding with extracted Low intensity remains an observed protein flag when RNA passes. Medium/High HPA staining retains its hold/exclusion, and Accepted literature positives without an extracted intensity retain their exclusion. Low staining never supplies negative-IHC credit. Review access (abstract/full text) is recorded separately and never erases a known positive. Every imported finding is audited in the protein-review table, alongside HPA protein-level decisions.

Evidence and limitations
PRAME's 12-nTPM cardiac fibroblast measurement and 20.3-nTPM colon undifferentiated-cell measurement are retained; the new ceilings are 16 and 32. Its adrenal bulk 3.6 nTPM is below the new Vital ceiling 4. Its adrenal protein finding is explicitly Low in the primary abstract and remains a positive protein flag; it is not discarded because of limited source access. IMA203 clinical evidence remains separate and does not participate in admission. See the target evidence assessment and primary adrenal-protein report.
Controlled fibroblast depletion has been tolerated in mouse studies; that motivates separating stroma from cardiomyocytes but does not validate these human cutoffs. Primary study. Direct epithelial targeting can produce severe colitis, including a dose-limiting signal in a small CEA-directed TCR trial; allowing greater mucosal expression is a research risk preference. Primary trial.
No numerical cutoff here predicts peptide presentation or injury severity. The permissive mucosal assumption and incomplete older protein reviews require particular scrutiny. These outputs do not overwrite the prior 343-group policy, released classifications or forbidden sequence references.
Reproduction
Run python scripts/cta_compartment_report.py. Changed cell compartments, bulk contexts, per-layer effects, counts, and provenance retain the decisions. Multi-locus values are summed before assessment; unpaired DICE and corneal detection uncertainty remain explicit. Figures also have SVG versions.
