-# Lan Mouse Agent Instructions
-
-## Overview
-
-Lan Mouse is an open-source Software KVM sharing mouse/keyboard input across local networks. The Rust workspace combines a GTK frontend, CLI/daemon mode, and multi-OS capture/emulation backends for Linux, Windows, and macOS.
-
-## Core principles
-
-- **Scope discipline.** Only implement what was requested; describe follow-up work instead of absorbing it.
-- **Clarify OS behavior.** Ask when requirements touch OS-specific capture/emulation (they differ significantly).
-- **Docs stay current.** Update [README.md](README.md) or [DOC.md](DOC.md) when touching public APIs or platform support.
-- **Rust idioms.** Use `Result`/`Option`, `thiserror` for errors, descriptive logs, and concise comments for non-obvious invariants.
-
-## Terminology
-
-- **Client:** A remote machine that can receive or send input events. Each client is either _active_ (receiving events) or _inactive_ (can send events back). This mutual exclusion prevents feedback loops.
-- **Backend:** OS-specific implementation for capture or emulation (e.g., libei, layer-shell, wlroots, X11, Windows, macOS).
-- **Handle:** A per-client identifier used to route events and track state (pressed keys, position).
-
-## Architecture
-
-**Pipeline:** `input-capture` → `lan-mouse-ipc` → `input-emulation`
-
-- **input-capture:** Reads OS events into a `Stream<CaptureEvent>`. Backends tried in priority order (libei → layer-shell → X11 → fallback). Tracks `pressed_keys` to avoid stuck modifiers. `position_map` queues events when multiple clients share a screen edge.
-- **input-emulation:** Replays events via the `Emulation` trait (`consume`, `create`, `destroy`, `terminate`). Maintains `pressed_keys` and releases them on disconnect.
-- **lan-mouse-ipc / lan-mouse-proto:** Protocol glue and serialization. Events are UDP; connection requests are TCP on the same port. Version bumps required when serialization changes.
-- **input-event:** Shared scancode enums and abstract event types—extend here, don't duplicate translations.
-
-## Feature & cfg discipline
-
-- Feature flags live in root `Cargo.toml`. Gate OS-specific modules with tight cfgs (e.g., `cfg(all(unix, feature = "layer_shell", not(target_os = "macos")))`).
-- Prefer module-level gating over per-function cfgs to avoid empty stubs.
-- New backends: add feature in `Cargo.toml`, create gated module, log backend selection.
-
-## Async patterns
-
-- Tokio runtime with `futures` streams and `async_trait`. Model new flows as streams or async methods.
-- Avoid blocking; use `spawn_blocking` if needed. Prefer existing single-threaded stream handling.
-- `InputCapture` implements `Stream` and manually pumps backends—don't short-circuit this logic.
-
-## Commands
-
-```sh
-cargo build --workspace                                    # full build
-cargo build -p <crate>                                     # single crate
-cargo test --workspace                                     # all tests
-cargo fmt && cargo clippy --workspace --all-targets --all-features  # lint
-RUST_LOG=lan_mouse=debug cargo run                         # debug logging
-```
-
-Run from repo root—no `cd` in scripts.
-
-## Testing
-
-- Unit tests for utilities; integration tests for protocol behavior.
-- OS-specific backends: test via GTK/CLI on target OS or document manual verification.
-- Dummy backend exercises pipeline without real dependencies.
-- Verify `terminate()` releases keys on unexpected disconnect.
-
-## Workflow
-
-1. Clarify ambiguous requirements, especially OS-specific behavior.
-2. Implement minimal change; flag follow-up work.
-3. Add proportional tests; run `cargo test` on affected crates.
-4. Run `cargo fmt` and `cargo clippy --workspace --all-targets --all-features`.

-### Git pre-commit hook

-This repository includes a local git hooks directory `.githooks/` with a `pre-commit` script that enforces formatting, lints, and tests before allowing a commit.  It is optional to enable it, but it will prevent you from committing code with failing unit tests or that needs clippy/fmt fixes. To enable the hook locally:
-
-1. Make the hook executable:
-
-```sh
-chmod +x .githooks/pre-commit
-```
-
-2. Point git to the hooks directory (one-time per clone):
-
-```sh
-git config core.hooksPath .githooks
-```
-
-The `pre-commit` script runs `cargo fmt --all` (and fails if files were modified), `cargo clippy --workspace --all-targets --all-features -- -D warnings`, and `cargo test --workspace --all-features`.

+## Protocol
+Currently *all* mouse and keyboard events are sent via **UDP** for performance reasons.
+Each event is sent as one single datagram, currently without any acknowledgement to guarantee 0% packet loss.
+This means, any packet that is lost results in a discarded mouse / key event, which is ignored for now.
+
+**UDP** also has the additional benefit that no reconnection logic is required.
+Any client can just go offline and it will simply start working again as soon as it comes back online.
+
+Additionally a tcp server is hosted for data that needs to be sent reliably (e.g. the keymap from the server or clipboard contents in the future) can be requested via a tcp connection.
+
+## Bandwidth considerations
+The most bandwidth is taken up by mouse events. A typical office mouse has a polling rate of 125Hz
+while gaming mice typically have a much higher polling rate of 1000Hz.
+A mouse Event consists of 21 Bytes:
+- 1 Byte for the event type enum,
+- 4 Bytes (u32) for the timestamp,
+- 8 Bytes (f64) for dx,
+- 8 Bytes (f64) for dy.
+
+Additionally the IP header with 20 Bytes and the udp header with 8 Bytes take up another 28 Byte.
+So in total there is 49 * 1000 Bytes/s for a 1000Hz gaming mouse.
+This makes for a bandwidth requirement of 392 kbit/s in total _even_ for a high end gaming mouse.
+So bandwidth is a non-issue.
+
+Larger data chunks, like the keymap are offered by the server via tcp listening on the same port.
+This way we dont need to implement any congestion control and leave this up to tcp.
+In the future this can be used for e.g. clipboard contents as well.
+
+## Packets per Second
+While on LAN the performance is great,
+some WIFI cards seem to struggle with the amount of packets per second,
+particularly on high-end gaming mice with 1000Hz+ polling rates.
+
+The plan is to implement a way of accumulating packets and sending them as
+one single key event to reduce the packet rate (basically reducing the polling
+rate artificially).
+
+The way movement data is currently sent is also quite wasteful since even a 16bit integer
+is likely enough to represent even the fastest possible mouse movement.
+A different encoding that is more efficient for smaller values like
+[Protocol Buffers](https://protobuf.dev/programming-guides/encoding/)
+would be a better choice for the future and could also help for WIFI connections.
+
+## Security
+Sending key and mouse event data over the local network might not be the biggest security concern but in any public network or business environment it's *QUITE* a problem to basically broadcast your keystrokes.
+- There should be an encryption layer below the application to enable a secure link.
+- The encryption keys could be generated by the graphical frontend.
 
 
-## Detailed OS Support
+## Wayland support
+### Input Emulation (for receiving events)
+On wayland input-emulation is in an early/unstable state as of writing this.
 
-In order to use a device for sending events, an **input-capture** backend is required, while receiving events requires
+For this reason a suitable backend is chosen based on the active desktop environment / compositor.
-a supported **input-emulation** *and* **input-capture** backend.
 
-A suitable backend is chosen automatically based on the active desktop environment / compositor.
+Different compositors have different ways of enabling input emulation:
 
-The following sections detail the emulation and capture backends provided by lan-mouse and their support in desktop environments / operating systems.
+#### Wlroots
+Most wlroots-based compositors like Hyprland and Sway support the following
+unstable wayland protocols for keyboard and mouse emulation:

+- [wlr-virtual-pointer-unstable-v1](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1)

+### Input capture
 
+To capture mouse and keyboard input, a few things are necessary:
+- Displaying an immovable surface at screen edges
+- Locking the mouse in place
+- (optionally but highly recommended) reading unaccelerated mouse input
