MIN_SCAN_INTERVAL_MS

Minimum time between the starts of two scan attempts, in milliseconds — the fastest cadence and the loop's poll granularity. Scans do not fire more often than this even while walking quickly. See RESCAN_DISTANCE_METERS for how the effective cadence adapts to movement.

Lowering this speeds up the three cases that are rate-limited by it — acquiring the first fix, retrying after a failed scan, and re-scanning while walking — at the cost of battery and heat. It does not cause continuous scanning while the user is stationary and already localized: the movement-aware gate suppresses those scans regardless. On a device where a single scan takes longer than this interval, scan duration sets the pace instead and this value has no effect.
