 # VoiceCat
 
-Self-hosted, native voice & text chat in the spirit of classic TeamSpeak / Mumble —
-channel-based voice, channel + private text, one server you run yourself. Plain **TCP**
-(control) and **UDP** (media), no WebRTC. Encrypted by default. A shared **C++ core**
-(`libvoicecat`) drives native clients (Swift on macOS/iOS, C# on Windows) and the server.
+VoiceCat is a self-hosted, channel-based voice and text chat system built on .NET 10. It uses
+TLS 1.3 for protobuf control traffic and authenticated encrypted UDP for Opus media. There is
+no WebRTC, central directory, or plaintext mode.
 
-> **Status:** Design complete in [`docs/`](docs/). M1–M5 are implemented — real TLS control
-> plane, encrypted UDP voice (Opus), multi-stream, TOFU identity pinning, channel tree,
-> permissions, moderation, disconnect/keepalive/reaper. Windows WinForms C# client shipped
-> (M4). macOS/iOS Swift client is next. See [`PROGRESS.md`](PROGRESS.md) and
-> [`docs/roadmap.md`](docs/roadmap.md).
-
-## Read the design first
-
-The [`docs/`](docs/) folder is the source of truth. Start at [`docs/README.md`](docs/README.md),
-then `architecture` → `protocol` → `voice` → `security` → `tech-stack` → `deployment` →
-`roadmap`.
+The repository contains a managed server, CLI, shared client/audio core, and native Windows,
+macOS, and iOS user interfaces. A small C library supplies Opus/RNNoise, and a small Swift iOS
+extension captures ReplayKit application audio.
 
 ## Build
 
-The default development preset is **`dev`** — it builds everything (server + tools + tests)
-with real vcpkg deps. It works on Windows, Linux, and macOS (vcpkg triplet auto-resolved).
-
 ```bash
-# one-time vcpkg setup (bundled as a submodule, pinned to vcpkg.json's builtin-baseline):
-git submodule update --init vcpkg
-./vcpkg/bootstrap-vcpkg.sh                  # .bat on Windows
-
-# configure + build + test:
-cmake --preset dev
-cmake --build --preset dev
-ctest --preset dev                          # 21 behavior tests
+./dotnet/build-native.ps1
+dotnet restore dotnet/VoiceCat.slnx --locked-mode
+dotnet build dotnet/VoiceCat.slnx -c Release --no-restore
+dotnet test dotnet/VoiceCat.slnx -c Release --no-build
 ```
 
-To use an external vcpkg checkout instead, set `VCPKG_ROOT=/path/to/vcpkg` (or
-`$env:VCPKG_ROOT` on PowerShell) — it always takes priority over the bundled submodule.
-
-Artifacts land in `build/dev/bin/` (`voicecat-server`, `vccli`, `voicecat-admin`).
-
-The `skeleton` preset (no vcpkg deps, stubs only) is a fast smoke check that needs no
-third-party libraries:
-
-```bash
-cmake --preset skeleton && cmake --build --preset skeleton && ctest --preset skeleton
-```
-
-See [`docs/building.md`](docs/building.md) for the full preset matrix (including `release`,
-`server-release`, `windows-client`, and Apple platform scaffolding).
+See [CLAUDE.md](CLAUDE.md) for the developer map, [docs/README.md](docs/README.md) for current
+contracts, and [PROGRESS.md](PROGRESS.md) for the short release handoff.

-## License
+The remaining C++ implementation and old Swift applications are unsupported retirement
+sources. They are not compatibility targets or architectural authorities.
 
-Permissive-only dependencies (no GPL/LGPL) so the project can be redistributed freely,
-including closed-source. Project license: TBD (see [`docs/tech-stack.md`](docs/tech-stack.md) §5).
+## Non-negotiable constraints
+
+- Encryption is mandatory.
+- No GPL or LGPL dependencies.
+- Real-time audio callbacks never allocate, lock, block, or perform I/O.
+- Accessibility is a release requirement on every client platform.
