# Scorer v2 report (rule-based, no LLM)

Scorer: `rule-v2` (scorer_v2.py + lexicon_v2.py + rubric.v2.json); self-test: scorer_v2_selftest.py (19 known cases, all must pass). Scope: every bank llava text in release r1 (TCGA 842 bank slides, BRACS final bank 460, EBR 2,019), 3 prompts each; BRACS scored twice (scope bracs-fine and bracs-coarse, same texts).

## Claims allowed
CONSISTENT / CONTRADICTED / UNINFORMATIVE means consistent or inconsistent with the confirmed label as defined by cited free sources (rubric.v2.json). It is NOT a statement of pathological correctness. No pathologist reviewed anything. The scorer rules and the earlier hand reads were written by the same author, and the 95.6% hand agreement is therefore weak support; the independent rater check is a v3 item.

**TCGA caveat: possibly train-contaminated (WSI-LLaVA was trained on TCGA; WSI-Bench is TCGA-derived). Every TCGA text-derived number below carries this caveat. The exact slide overlap with the WSI-Bench split was not checked.**

## Changes vs scorer v1 (KONGMING-REVIEW P0-3 / P0-4)
- Four stretched rubric entries repaired (secretory psammoma removed, secretory no-atypia and fibrous no-whorls downgraded, FEA columnar single-source).
- Rule fixes: normal-tissue phrase no longer matches normal-breast; negation across an adverb ("not prominently observed"); bare glioma is a hypernym compatible with any glioma label; hyperchromasia is not pleomorphism; hedges (may represent, unlikely, rather than); generic "invasive carcinoma" on lung is not ductal; N vs PB not separated by severity.
- Contradiction rates are reported by basis. Headline = diagnosis-driven only; feature-driven rows are listed apart.

## BRACS non-IC framing

type_grade on BRACS non-IC bank slides: 347/348 contradicted by diagnosis; on IC slides: 4/112 contradicted. The rate mostly reflects the label mix (the model names a carcinoma on almost every slide), not a per-slide read.

## Use rules
- Cite a llava text only if CONSISTENT. Never cite CONTRADICTED or UNINFORMATIVE.
- llava_limits has no scorable content (boilerplate); do not say it carries no information.
- Wilson intervals assume independent slides; BRACS slides share patients (patient ids not in the release), EBR patient ids unknown: intervals are optimistic.
- Contradictions are label-space judgements ("label-inconsistent naming"), not morphological errors.
