Alliance and treaty creation retry hardening (Issue #739)
2026-04-24
- Hardened `/api/alliances/create` and `/api/treaties/create` against transient database contention by broadening retryable error detection and extending deterministic retry backoff steps.
- Players should now see fewer failed alliance-create and treaty-create attempts during short-lived database lock/serialization bursts.
- No alliance, treaty, or war-balance rules changed; this update is reliability hardening for transient write contention only.
