Abstract
Introduction In addition to sensorineural hearing loss, Waardenburg Syndrome (WS) may present with variable pigmentation of skin and choroid, which may simulate other life-threating conditions (e.g. melanoma).Case Report Two siblings ostensibly presented with unilateral choroidal pigmentary abnormalities concerning for choroidal tumour. Serial ophthalmic examination documented no lesion growth (base or height) whilst the apparent syndromic features (i.e. iris hypochromia, profound sensorineural hearing loss, SNHL), family history (autosomal dominant inheritance) and positive genetic testing (pathogenic MITF variant) led to a revised diagnosis of Waardenburg Syndrome type 2A.Conclusion Sectoral preservation of choroidal pigmentation in WS is rarely associated with choroidal malignancy. Awareness of syndromic features (e.g. SNHL) and access to genetic testing may facilitate early accurate diagnosis (i.e. allay concern for malignancy), enable treatment of modifiable features (e.g. SNHL) and identify other affected relatives.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
