| Aspecto | Regla |
|---|---|
sampling |
features resampled or aligned to a declared analysis rate; original timestamps retained |
perSample |
timestampNs validity mask value unit frameId covariance or quality latency estimate provenance |
normalization |
per-athlete/session normalization may be added but raw metric values and transforms remain available |
missingData |
mask explicitly; do not zero-fill as physical measurement |
derivatives |
computed from filtered signals with declared window/estimator and edge handling |
causality |
each feature declares causal, centered or acausal construction |
Cualquier feature centrada o suavizada con frames futuros debe
declararse acausal. Usarla en una evaluación online sería
leakage temporal.
