Merged
Conversation
Optional body weight (30–300 kg) stored per user, exposed in Settings UI with step=0.1 input. Used downstream for W/kg power metrics and Uth VO₂max formula (15 × HRmax / HRrest). - V31 Flyway migration: nullable FLOAT column with CHECK (> 0 AND ≤ 500) - GET /api/profile: weight_kg included in response - PATCH /api/profile: accepts weight_kg with server-side range validation - Settings page: weight input between sex select and save button - GDPR export: weight_kg included in user data export (Art. 20) - JS tests: weight value sent in fetch body; null when field empty Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
