`details` is the raw response from `Garmin.get_activity_details()`. Each sample in
|

|
|
`activityDetailMetrics` stores values positionally in `metrics`; the position-to-name
|
||
|
|
mapping is given by `metricDescriptors[].metricsIndex`/`key` and varies by device and
|
||
|
|
activity type. Descriptors with a missing, non-int, or negative `metricsIndex` are
|
||
|
|
skipped, and a sample missing a channel entirely (index out of range for that sample)
|
||
|
|
simply omits that key rather than raising. Duration keys (`sumDuration`,
|
||
|
|
`sumElapsedDuration`, `sumMovingDuration`) are not equivalent and are passed through
|

|
|
unchanged under their own names — callers must pick the one they mean.
