Kotlin retry loop with capped exponential backoff

import kotlin.random.Random

fun <T> retry(
    attempts: Int = 5,
    baseMs: Long = 100,
    maxMs: Long = 5_000,
    block: () -> T,
): T {
    var delayMs = baseMs
    repeat(attempts - 1) {
        try {
            return block()
        } catch (e: Exception) {
            // full jitter avoids synchronized retries
            val cap = minOf(delayMs, maxMs)
            Thread.sleep(Random.nextLong(cap / 2, cap + 1))
            delayMs = minOf(delayMs * 2, maxMs)
        }
    }
    return block()
}
