get_metric_history
The HISTORY of a measured number — FTP, threshold pace, LTHR, max HR, weight, body fat, VO2max, MAP, LT1/LT2, lactate, ferritin, haemoglobin, RHR, HRV. The profile carries the CURRENT value and only that (it is overwritten in place), so this is the only way to answer "is it moving": weight trend, FTP across a season, LT2 between two lab tests, a falling ferritin. Rows carry source — profile | lab | field-test | estimate | self-report — and a lab number and a field estimate are NOT the same measurement twice: say which you are comparing. Deliberately not in the turn snapshot; call it when the question is about a trend, not about today.
