Summary

• vitallens-core 0.4.0: more accurate HRV (lower RMSSD/SDNN bias), LF/HF only after 120 s, pNN50 from 25 s.
• Stream timestamps: the README and examples/live.py use time.monotonic() instead of time.time(), which can jump when the system clock is adjusted. The push() docstring asks for the capture time, or the time right after reading the frame.
• Docs: docs/results.md now covers only what is specific to Python and links to the shared guide at https://docs.rouast.com/guides/results/ for structure, keys, availability and confidence. It also corrects the rolling vitals description: they are on by default, under rolling_vitals with the same keys as vitals, and data is returned as lists. The estimate_rolling_vitals docstring is fixed to match.

Checked, no change needed

• Downsampling: prpy box resampling above 2x, with the size from the model config.

Verification

• pytest: 126 passed, 3 skipped.
• Ran the client with method="pos" on examples/sample_video_1.mp4 to confirm the result keys, types and rolling vitals described in the docs.
