SVD demographic baseline -- age and sex only, no audio

SCREENING CONFOUND ESTABLISHED SCOPE-LIMITED svd metadata only

Scope caveat. This run is a pilot slice -- 1,853 of the 13,535 speakers measured elsewhere on svd. It may satisfy the repeat contract and still be a narrower measurement than a later run on the same corpus; both facts are shown because either alone would mislead.

The recruitment asymmetry underneath it

Mean age 28.3 years healthy vs 51.0 pathological — a gap of 22.7 years over 1,356 pathological and 869 healthy sessions.

200 of 1,853 speakers contribute more than one session (max 24). A recording-level split leaks every one of them across folds.

Published benchmark for orientation: UAR 85.22 (arXiv:2410.10537) — different metric, indicative only

What this page does not have

No 7-step reasoning entry exists for this run. The sibling convention renders Diagnosis · Citations · Hypothesis · Prediction · Verdict · Learning on every per-experiment page, sourced from a reasoning_annotations.json. This program never wrote one, and neither does it keep an append-only experiment_log.jsonl; the run history is the set of artifact files listed on the run ledger, ordered only by their write time. The pre-registered prediction for this run does exist — it is on the hypothesis registry, but this run predates the registry and has no pre-registered prediction of its own. Everything else on that convention’s checklist is absent here and is shown as absent rather than quietly dropped.
