pub const RETRY_BACKOFFS: &[Duration];Expand description
v0.7.0 K6 — exponential-backoff retry ladder for failed webhook
deliveries. The dispatcher attempts the initial POST, then up to
three retries spaced [200ms, 1s, 5s] apart. After the final retry
fails the row lands in subscription_dlq for K7’s inspector tool
to surface. Exposed as a constant so tests can reason about the
total wall-clock budget (≈ 6.2s + per-attempt timeout).
