- Use the existing Topiary-backed
is_allele_scoped_kinddefinition; do not mistake allele-free processing or half-life observations for malformed MHC evidence. Parse stated allele identifiers with mhcgnomes, including non-human alleles and class-II pairs, without hand-written HLA prefix rules. - Reject malformed allele-scoped leaves before filtering/scoring in native flat and serialized inputs, LENS and pVACseq. Include the input filename, row and offending kind/comparator where those are available.
- Keep rendering defensive for directly constructed legacy objects: show an unavailable allele/score, never invent an allele, a zero or patient evidence. Missing scores remain numeric missing values in tabular output.
- Test nested non-WT comparators, blank/null spellings, valid class-II and mouse alleles, allele-free kinds, report rendering and actual load paths. No ranking policy changes. Review, lint, full tests, B16 smoke, green CI and deployment are required before closing the issue.
