Abstract
A 41-year-old male presented with progressive leg weakness and difficulty with micturition. He had otherwise been well. Clinical examination was normal apart from reduced power (3–4/5) in his lower limbs and a palpable bladder. The patient was catheterized and had a 1000 ml residual volume. Initial blood tests and magnetic resonance imaging of his brain were normal, but magnetic resonance imaging of the spinal cord revealed extensive abnormality. Figures 1–3 are selected magnetic resonance images of the cervical and upper thoracic cord. Figure 1 shows extensive high signal within the cord on T2 weighting, extending from C3 to the upper thoracic region. The cord itself is expanded and the altered signal extended to the T10 level on further imaging. Figure 3 shows meningeal enhancement (arrows) and this was evident along the whole cord to the conus. There was no compressive lesion. These appearances are consistent with a transverse myelitis. Lumbar puncture showed an increased CSF white cell count, reduced glucose and increased protein levels. The patient was commenced on intravenous methylprednisolone and cefotaxime. His leg weakness progressed with power falling to 0/5. A sensory level was established at T2. Further blood tests showed a normal serum angiotensin-converting enzyme level, no evidence of tuberculosis, normal autoantibodies and negative viral screen including HIV. Syphilis serology (i.e. venereal disease research laboratory (VDRL), Treponema pallidum haemagglutination assay (TPHA) and serum enzyme-linked immunosorbent assay (ELISA)), however, was strongly positive. Further lumbar puncture showed positive CSF antibodies to Treponema pallidum. The diagnosis of syphilitic transverse myelitis was made and his antibiotics were changed to intravenous benzylpenicillin. The patient made a full neurological recovery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
