Da Ring R26 build 90051

Build 90051 - confirmed Da Ring R26 community build

This is the confirmed working community build for the MoYoung / CRRepa
Da Ring R26 (VRing, firmware MOY-R263-2.2.2).

Highlights

• Autonomous ring-side HR, HRV, and temperature history remains enabled.
• Fresh history is pulled when Gadgetbridge connects.
• Battery-conscious, interval-gated spot measurements with night protection.
• Blood pressure is measured first in the spot rotation.
• Sleep day 0 and day 1 are re-fetched to recover sessions finalized after an
  early morning sync.
• Health Connect export for heart rate, HRV, sleep, steps, temperature, SpO2,
  blood pressure, calories, distance, and detected exercise.
• Correct 30-minute Health Connect step-slot durations.
• Configurable activity-detection sensitivity.

Installation

1. Back up existing Gadgetbridge data.
2. Download and install the attached APK.
3. Pair the device advertised as VRing.
4. Grant the desired Health Connect permissions. Blood pressure requires the
   Blood pressure (write) permission.

Limitations

• Blood pressure is a non-medical wellness estimate.
• BP, SpO2, and stress are spot measurements, not continuous timelines.
• Continuous 1 Hz Live Activity HR remains hardware-limited (0xFF response).
• This build is confirmed on R26 / MOY-R263-2.2.2; related Da Rings devices
  require separate validation.
