Every term used to interpret wearable sleep data — defined once, on its own page.
The Lexicon is Sleepgenic's structured vocabulary. Each entry is a single definition on its own URL, machine-readable as a DefinedTerm, cross-linked from the Methodology, the Sleep Interpretation Library, and every Weekly Report. Where the Methodology defines how the dataset is read, the Lexicon defines what every term in it actually means.
Three terms anchor the rest: Score Layer, Physiology Layer, and Context Layer — the named layers of the Sleepgenic Three-Layer Interpretation Model, the framework Sleepgenic uses to read every wearable signal.
