+> ### TawCorp hifast-server (internal fork)
+>
+> This repository is the **canonical** TawCorp fork of [perfect-panel/server](https://github.com/perfect-panel/server). Migrated from `git.kxsw.us/HI-VPN/hi-server` on **2026-06-03**; the old Gitea remote is deprecated — do not push or pull from it.
+>
+> - **Development workflow (required reading for internal contributors)**: [`doc/development-workflow-zh.md`](doc/development-workflow-zh.md)
+> - **Branch model**: `internal` (dev mainline, auto-deploys to staging) → `main` (release)
+> - **Merge policy**: PR + architect review + GitHub UI "Squash and merge"; direct push to `internal`/`main` is blocked by `lefthook` pre-push and forbidden by policy
+> - **Issue tracker**: Multica workspace `Hifast` (prefix `HIF-`)
+>
+> External contributors: read [`CONTRIBUTING.md`](CONTRIBUTING.md) for the upstream-compatible baseline.
