Schofield basal metabolic rate (kcal/day) by age band and sex — the WHO/ Schofield coefficients ecore's BMR path (ELF `0x10d7e4`) uses. `sex`: 0=male,

Decode the packed-nibble 30-second stage array into per-epoch stage codes (0..4). Two epochs per byte; a byte `< 0x10` ends the series.

Build an event from a parsed history-event packet (tag >= 0x41).

Convenience: store a battery reading.

Bake the libtorch rpath into the binary when built with `--features torch`, so `oura sessions` finds `libtorch_*.dylib` at runtime without the caller

Build a packet from a tag and payload.

Nightly temperature (centi-°C) from per-sample temps (centi-°C; 0 = invalid). `None` if fewer than 4 valid 30-sample windows passed the range gate.

Open an in-memory database (useful for tests).

Parse a notification frame leniently. Returns `None` if too short to hold a header. If the declared length disagrees with the buffer, the remaining by

Parse an ACM measurement-indication frame (tag `0x33`) into its samples.

A product-info response (tag `0x19`): a status byte then ASCII/bytes.

RData status-code name (from the decompiled app's `RDataStatusCode`).

Serve the game at `127.0.0.1:port` (see [`crate::motion_server::run`]).

Serve `index_html` at `127.0.0.1:port`. Streaming is toggled from the page; each "start" arms the ring for `minutes` (so it auto-stops if the page clo

0-dim float32 scalar, matching Python's `torch.tensor(x)`.

Enable the async notification flags so the ring pushes events.

Blood-oxygen saturation. Ported from ecore `spo2_simple_calculate @ 0x22ad50`: a quadratic calibration of the red/IR ratio `R` → SpO2 %, clamped to [0

Walking distance from step count, ecore `actinfo_steps_to_meters @ 0x1cd624`: `0.762 m` per step.

Temperature deviation (centi-°C) = nightly temperature − personal baseline mean.

Normalized deviation of `sample` from the mean (readiness contributors are built on this). `None` if the deviation hasn't accumulated yet.
