cuda::experimental::stf::sump::backoff_t

struct backoff_t

Re-attempts with decorrelated-jitter delays.

Uses the AWS “Exponential Backoff and Jitter” decorrelated algorithm: plain exponential backoff synchronizes clients into retry storms. Randomness is hook-local xorshift state; there is no global state and no <random> dependency.

The code-channel hook: re-runs a status-returning action after each delay while its result fails; exhaustion passes the latest status through.

An exception from a re-run escapes.
