Deterministic metabolic fueling calculation, aerodynamic split pacing, and threshold kinematics engineered for endurance athletes across road, trail, time-trial, and long-course triathlon disciplines. Zero fabricated metrics, zero synthetic telemetry.
Stateless Rust/Axum HTTP host in europe-west3 with sub-200ms PostgreSQL 16 readiness gates, Cloud Tasks queue checks, and zero-downtime traffic promotion.
Zero-flicker Night Run OLED (#060B11) and Daylight Lab (#F8FAFC) Cyan-to-Mint (#00F0FF -> #00FF9D) theme engine synchronized across Rust SSR pages and the Flutter WebAssembly client shell.
Deterministic carbohydrate oxidation (g/hr), sweat sodium concentration (mmol/L), and fluid volume solver calibrated to ambient temperature and intensity zone.
Segment-by-segment normalized power, elevation gradient resistance, and negative-split pacing model for time trials and long-course cycling.
Critical speed (CS / D-prime) modeling, pace-at-heart-rate decoupling diagnostics, and metabolic cost per kilometer across road and trail surfaces.
Asynchronous background worker execution via oxivel-worker and Google Cloud Tasks for high-frequency GPS, power meter, and heart-rate stream normalization.
