How we decide a result is real.

A clear evidence standard sits between the lab and every claim. Each result carries how it was produced — rigor is built into the pipeline, not added after.

The gates

Contract gateRows match the logger schema; provenance is verified.

Model gateBaseline passes clean-vs-post-use, IQOS-vs-vape, time-bucket & false-alarm thresholds.

Adversarial gateLabel-shuffle & metadata-only checks must fail to act as detectors.

Evidence gateEach result is tagged with the stage it was produced at, from bench to validated.

Storage gateEvery bundle has a manifest + samples; filenames carry no labels.

Evidence ladder

Every result is tagged with how it was produced, so we always know what a number is allowed to mean.

What we are working toward: bench and chamber runs that move each result up the ladder — from pipeline baseline to validated.
