Stop reading the panel. Start moving the levers.

Drugs that succeed in Phase II routinely fail in Phase III. The failure is rarely the molecule — it is the translation: the endpoint, the population, the powering, the enrichment cutoff. Below is a bench. Move a lever and watch the shape of the answer change.

Everything on this bench is a hand-authored fixture. It is not the Talaria engine, and it is not about any real drug. We print its entire arithmetic further down the page, because a bench you cannot audit is a bench you should not believe.

The expression distribution in this field is arbitrary. It is a fixture, not a prevalence estimate, and the scale is unitless — it is not TPS, not a percent, and not any real assay.

The line across the top of the field is the fixture curve for lever 01 under the current bundle — hand-authored, drawn, and named. It is not a sensitivity analysis.

The field renders the population. Lever 01 is the lever that changes the population, so lever 01 is the lever the field shows. That is a rendering choice, not a ranking.

No bypass
Residual failure shape · synthetic composite

    The faint bar is this run's Day-0 shape; the solid bar is the shape under your bundle. A display convention for a fixture, not a result. Renormalizes to 100% of the residual failure shape. Enrichment is not free. It buys signal with accrual.

    Panel register · reconstruction

    What a counterfactual panel looks like

    The bundle diff: what you moved, and away from what. One joint schematic outcome for the whole bundle — never a per-lever delta, because a per-lever delta is a ranking.

    The fourth column is empty for all five levers, including lever 01. In production each lever carries its own causal interval and sensitivity analysis. This page carries none, for any lever, because this page has no engine behind it.

    The public recordpublished facts only · no probability
    Illustrative, not predictive. A public-record reconstruction of the design lever that separated two known outcomes, shown to explain the shape of a counterfactual panel. Not a retrospective Talaria prediction; no accuracy claim is made from it.
    Two first-line NSCLC checkpoint-inhibitor Phase III trials: population as designed, and outcome
    Population as designedOutcome
    Broad, all-comers MISSED primary endpoint
    Above a high PD-L1 expression cutoff HIT primary endpoint

    In first-line non-small-cell lung cancer, two checkpoint-inhibitor Phase III trials read out within a year of each other. One enrolled a broad, all-comers population. The other enrolled only patients above a high PD-L1 expression cutoff. The broad trial missed its primary endpoint. The enriched trial hit. The molecule was not the difference. The enrichment cutoff was the difference — a single design parameter, chosen at design time, free until the moment it wasn't.

    This register holds facts and has no slot for a probability. It names no sponsor, no molecule and no NCT ID, and it never receives a number from the bench above.

    The real engine ships with its levers attached

    This bench is a fixture. The engine behind M01 is not — and every prediction it emits arrives with a counterfactual panel, an uncertainty envelope, and an audit trail. Talaria is pre-deployment. We are opening a founding cohort ahead of it.
