• Hotfix v1.9.11 / v1.9.12 build failure: PR [#763](https://github.com/therealaleph/MasterHttpRelayVPN-RUST/pull/763) فیلد جدید `block_doh` به `Config` اضافه کرد ولی `src/bin/ui.rs::FormState` (که Config رو با struct literal می‌سازه) به‌روز نشد، در نتیجه `mhrv-rs-ui` در CI با `error[E0063]: missing field 'block_doh'` کامپایل نشد. هر دو release CI v1.9.11 و v1.9.12 fail شدن — هیچ binary منتشر نشد. این release همان تغییرات رو با fix UI ship می‌کنه. **پیامد محصول:** v1.9.13 = v1.9.11 + v1.9.12 + UI compile fix. تست: 180 lib + 35 tunnel-node + UI release-mode build همه green.

• Hotfix v1.9.11 / v1.9.12 build failure: PR [#763](https://github.com/therealaleph/MasterHttpRelayVPN-RUST/pull/763) added a new `block_doh` field to `Config` but didn't update `src/bin/ui.rs::FormState` (which constructs `Config` via a struct literal), so `mhrv-rs-ui` failed to compile in CI with `error[E0063]: missing field 'block_doh'`. Both v1.9.11 and v1.9.12 release CI runs failed and shipped no binaries. This release is the same set of changes with the UI compile fix included. **Product impact:** v1.9.13 = v1.9.11 + v1.9.12 + UI compile fix. Tests: 180 lib + 35 tunnel-node + UI release-mode build all green.
