Retry Policy Builder
Dial in maxAttempts, initialDelay, maxAge, and the safety flags that make fetch retry safe for keepalive beacons. The simulator runs 100 synthetic beacons and shows which requests retry, which are blocked by policy, and which age out before another attempt.
The proposed API exposes only the final fetch() result to page script. This page models the browser-managed retry queue so you can inspect the policy decisions that would otherwise happen below JavaScript.
