// TestFastestPositiveDurationIgnoresNonPositiveValues guards a real reported
// bug: the storage retention sweep's ticker cadence used to be driven purely
// by the shared TELESRV_STORAGE_RETENTION_MAX_AGE default (e.g. 30 days),
// even when a much shorter TELESRV_STORAGE_RETENTION_MAX_AGE_<CATEGORY>
// override was configured -- so a category set to "1 minute" would still
// only actually get swept on the shared default's own slow cadence (or, if
// the shared default was 0, would disable the sweep outright). The worker
// must be handed the fastest positive age across the default and every
// override instead.
