WHY IT NEEDS A POLICY

Why tp_log_metrics needs a policy

This tool writes health metric data to TrainingPeaks for a specific date. It creates new records but is reversible in principle (entries can be updated or deleted). No financial, destructive, or execution risk is present. Misuse could result in incorrect health/training data being logged, affecting training recommendations, hence medium severity.

From the tool's definition 'Log health metrics (weight, HRV, sleep, steps, etc.) for a date' — creates/records new health data entries
