  "Description": "Provides tools for importing, parsing, and analysing raw\nactigraphy data from wrist-worn devices. Implements a full\nsleep analysis pipeline — off-wrist detection, main sleep\nperiod detection, nap detection, and WASO computation —\nvalidated epoch-for-epoch against the Condor circadiaBase\nPython reference pipeline using ActTrust hardware. Also\ncomputes standard non-parametric circadian rhythm variables\n(interdaily stability, intradaily variability, relative\namplitude, L5, M10). Device-specific parameter presets can be\nswapped to adapt the pipeline to other actigraph models.\nDesigned to complement slumbR in the Circadia Lab ecosystem.",
