─── about

Calibration substrate for clinical-trial outcome prediction under data-scarcity.

─── pipeline

  1. 01

    ctgov-fetch

    Trial metadata, arm structure, outcome definitions pulled from CT.gov v2. Fixture cache for the four pinned demo NCTs; live lookup for the advanced path.

  2. 02

    synthesis

    Indication-specific dispatcher generates a TrancheSpec — outcome family, arm assignments, prior-precedent substrate. Today: scd-vaso-occlusive and sod1-als dispatchers; SMA, C9-ALS, and SOD1-presymptomatic next.

  3. 03

    tabpfn-v2 inference

    Tabular foundation model runs in-context over the synthesized substrate. No per-indication training; the synthesis carries the inductive bias.

  4. 04

    ltt loss control

    Learn-Then-Test multi-alpha calibration. Empirical risk bounded below user-specified alpha across the chosen loss surface — what “calibrated” means here, precisely.

  5. 05

    discount-rate output

    The calibrated forecast surface, expressed as a discount-rate table over outcomes-based receivables — the deliverable a design partner takes away.

  6. 06

    audit substrate

    Every stage emits a typed event. Replayable; the TrancheSpec and the calibration alphas are visible end-to-end.

─── where the bounds fail

n < 45
Below this floor LTT loss control degrades; surfaced pre-stream as bounds:ltt in the validator.
indication outside coverage
No trained dispatcher for the inferred indication → structured refusal with the trained-coverage list visible. Not a degraded forecast.
paramType mismatch
Outcome measure cannot be coerced into a supported family (negbin / TTE / ordinal …). Disclosed at submit, not at stage four.

─── what this is and isn't

The demo wraps finnegas-v0; it does not introduce methodology. The methodology core was released 2026-05-16. The surface lets you exercise it on a real NCT, see the audit trail, and read the refusal when one is the honest answer. It is not a model picker, not a workflow chatbot, and not a notebook in a tab.
