+## Lightmapped water
+
+Xash3D FWGS supports lightmapped water, as an extension. It adds three new cvars and new worldspawn key values.
+
+### For level designers:
+
+If you're a level designer and intend to make your level to have lightmapped water, you can put these keyvalues to worldspawn entity description (always first entity in entities list):
+
+| Key                    | Value   | Description |
+| ---------------------- | ------- | ----------- |
+| `_litwater`            | integer | Set to any non-zero value to enable lightmapped water. Overrides `gl_litwater_force` cvar value. |
+| `_litwater_minlight`   | integer | Minimal lightmap value water surface will receive. Helps to avoid too dark areas when water isn't properly lit. If not set, defaults to zero. |
+| `_litwater_scale`      | float   | Scales up lightmap value for water surfaces. If not set, defaults to 1.0. |
+
+### For players:
+
+Some of the maps already have computed lightmap for water surfaces and sometimes water has been properly lit but the support hasn't been declared by the level designer.
+
+As a player, you can enable it in `Video options` menu or through console with `gl_litwater_force` cvar. There are also `gl_litwater_minlight` and `gl_litwater_scale` cvars that function similar to keys above. The default values has been set to `192` and `1.25` respectively to slightly avoid issues with maps that wasn't intended to have lightmapped water.

-# Steam broker protocol
-`sb_connect <ip:port> <server's steam id> <secure> <challenge>` - used for obtaining auth ticket during connection to GoldSrc server
+# Steam API Broker Protocol Specification
 
-`sb_disconnect <ip:port> <challenge>` - used for signaling broker about disconnecting from GoldSrc server
+## Overview
 
-`sb_gamedir <gamedir>` - used for signaling broker about game startup and for announcing started mod, so broker could choose proper AppID for Steam API initialization
+Due to proprietary nature of Steamworks SDK, it cannot be run on same amount
+of platforms supported by Xash3D FWGS, neither we can link library directly due to
+GNU GPLv3 license. 
 
-`sb_terminate` - used for signaling broker about game shutdown, ideally broker should be terminated too (and later restarted automatically and waiting for sb_gamedir message)
+However, here comes the broker, by running it (in trusted
+network, preferrably) on a machine that has Steam client installed, the
+engine can communicate with it, acquiring needed information to log-in into
+Steam protected multiplayer servers.
+
+## Key Characteristics
+
+Broker uses a simple TCP-based binary protocol with the following properties:
+
+- Single active session per connection: once a session is activated, the broker will reject all other TCP connections until the session is terminated.
+- All messages follow a consistent structure with a header, length, and payload: this is called a "frame".
+- Stateful interactions: commands affect the session state, and certain commands are only valid in specific states.
+- Numeric parameters are encoded in little-endian format for compatibility with majority of platforms.
+---
+
+## Frame Format
+
+All communication uses a fixed frame structure:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 4 bytes | ASCII | Frame start signature |
+| Length | 2 bytes | uint16_t (LE) | Size of payload in bytes |
+| Payload | N bytes | Binary | Command string or response data |
+
+**Notes**:
+- Header must be exactly `SBRK` (`53 42 52 4B` in hexadecimal form)
+- Maximum frame size: soft limit is 4096 bytes, hard limit is 65535 bytes (due to uint16_t usage)
+
+---
+
+## Session Lifecycle
+
+```
+┌──────────────┐
+│     IDLE     │ ← Initial state, accepts new TCP connections
+└──────────────┘
+       │ sb_gamedir
+       ↓
+┌──────────────┐
+│    ACTIVE    │ ← Session established, rejecting all of other TCP connections

+│    ACTIVE    │ ← Client shutting down game, terminating broker to reset Steam client state

+       │ sb_terminate
+       ↓
+┌──────────────┐
+│  RESTARTING  │
+└──────────────┘
+```
+
+---
+
+## Commands
+
+All commands listed below are meant to be sent from client to broker as payload of a frame. The broker will parse the command string and respond accordingly.
+
+### Session activation
+
+Activates the session and signaling game startup.
+
+**Format**: `sb_gamedir <gamedir>`
+
+**Response**: None
+
+---
+
+### Authentication ticket request
+
+Requests authentication ticket for a game server.
+
+**Precondition**: Session must be active
+
+**Format**: `sb_connect <ip:port> <server_steamid> <secure> <challenge>`
+
+**Parameters**:
+
+| Name | Description |
+|------|------------------|
+| `<ip:port>` | Game server address (e.g., `127.0.0.1:27015`) |
+| `<server_steamid>` | Server SteamID |
+| `<secure>` | 0 = insecure, 1 = secure |
+| `<challenge>` | Random value for reply prevention |
+
+
+**Response Format**:

+# XRCON Protocol Specification
+
+## Overview
+
+XRCON is a TCP-based remote console protocol implemented as a server within the engine. It provides an alternative to the legacy RCON (which operates over UDP as out-of-band packets). XRCON uses a framed binary protocol over a single persistent TCP connection, accepting at most one client at a time.
+
+Key characteristics:
+
+- Based on TCP (stream-oriented, reliable)
+- Default port is 27000
+- Maximum only one concurrent client
+- Binary framed protocol with a 12-byte header + variable-length payload
+
+
+
+## Configuration
+
+The XRCON server is controlled by two configuration variables, both restricted to privileged users:
+
+| Variable | Default | Description |
+|---|---|---|
+| `xrcon_enable` | `0` (disabled) | Master switch; when enabled, the server starts listening for connections |
+| `xrcon_address` | `127.0.0.1:27000` | Bind address and port; supports both IPv4 and IPv6. Changing this at runtime triggers a XRCON server restart (stop + rebind) |
+
+By default, XRCON binds only to localhost (`127.0.0.1`), providing a degree of access control. The server will not start listening until explicitly enabled.
+
+
+
+## Frame Format
+
+All XRCON messages are encapsulated in a framed binary format. Each frame consists of a fixed 12-byte header followed by a variable-length payload.
+
+### Header (12 bytes)
+
+| Offset | Size | Field | Description |
+|---|---|---|---|
+| 0 | 4 | Type | 4-character message type string (null-terminated, occupies 5 bytes in the structure but the 5th byte is padding) |
+| 4 | 4 | Version | Protocol version (32-bit unsigned integer, network byte order) |
+| 8 | 2 | Length | Total frame length in bytes, including the header (16-bit unsigned integer, network byte order) |
+| 10 | 2 | Handle | Handle or sequence number (16-bit unsigned integer, network byte order; currently always zero) |
+
+
+### Protocol Version
+
+The current protocol version is `0x000000D4` (212 decimal). The server also accepts `0x00D40000` for compatibility with certain third-party clients (e.g., CS2RemoteConsole).
+
+### Maximum Frame Size
+
+- Maximum payload per frame: 4096 bytes
+- Maximum total packet size (header + payload): approximately 4136 bytes
+- Receive buffer size: 4096 + 64 bytes
+- Transmit buffer size: 16384 bytes (4 × maximum frame size)
+
+### Byte Order
+
+Multi-byte integer fields (version, length, handle) are transmitted in **network byte order** (big-endian).
+
+
+
+## Message Types
+
+| Type | Direction | Description |
+|---|---|---|
+| `CMND` | Client → Server | Execute a console command |
+| `PRNT` | Server → Client | Console output / print message |
+| `CHAN` | Server → Client | Channel list (channel metadata) |
+| `AINF` | Server → Client | Application / server info |
+| `ADON` | Server → Client | Additional info / server name |
+
+### CMND — Client Command
+
+**Direction**: Client → Server
+
+Sent by the client to execute a console command on the server.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CMND"`, version, length, handle |
+| Payload | Variable | Raw command string (null-terminated) |
+
+The command string is injected into the engine's command buffer for execution. There is **no authentication** — any connected client may execute arbitrary commands.
+
+### PRNT — Server Print
+
+**Direction**: Server → Client
+
+Sent by the server to stream console output to the connected client.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"PRNT"`, version, length, handle |
+| Channel ID | 4 bytes | Channel identifier (unsigned 32-bit integer; always 0 for "Console") |
+| Padding | 20 bytes | Reserved (5 × 32-bit unsigned integers, all zero) |
+| Red | 1 byte | Red color component (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha / opacity component (always 255) |
+| Text | Variable | The console output text (up to 4096 bytes) |
+
+
+### CHAN — Channel List
+
+**Direction**: Server → Client
+
+Sent by the server during the initial handshake (and potentially later) to describe the available console output channels.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CHAN"`, version, length, handle |
+| Channel Count | 2 bytes | Number of channel records (unsigned 16-bit integer; always 1) |
+
+Each channel record (58 bytes):
+
+| Field | Size | Description |
+|---|---|---|
+| Channel ID | 4 bytes | Unique channel identifier (unsigned 32-bit integer; always 0) |
+| Unknown 1 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Unknown 2 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Default Verbosity | 4 bytes | Default verbosity level (unsigned 32-bit integer; always 5) |
+| Current Verbosity | 4 bytes | Current verbosity level (unsigned 32-bit integer; always 5) |
+| Red | 1 byte | Red color component for the channel (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha component (always 255) |
+| Name | 34 bytes | Channel name string, null-padded (always `"Console"`) |
+
+Total payload size for this frame: 2 + 58 = 60 bytes.
+
+### AINF — Application Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after a client connects, before `ADON` and `CHAN`.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"AINF"`, version, length, handle |
+| Payload | 77 bytes | All zeros (placeholder / reserved for structured application information) |
+
+This packet currently serves as a placeholder and contains no meaningful data. It may be extended in future versions to carry structured metadata about the server application.
+
+### ADON — Additional Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after `AINF` during the connection handshake.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"ADON"`, version, length, handle |
+| Unknown | 2 bytes | Reserved (unsigned 16-bit integer; always 0) |
+| Name Length | 2 bytes | Length of the name string (unsigned 16-bit integer) |
+| Name | Variable | Server name / identifier string (e.g., `"HLDS"`) |
+
+This packet carries the server application name, which is a short string identifying the server type (e.g., `"HLDS"` for Half-Life Dedicated Server).
+
+
+
+## Security
+
+XRCON has **no built-in authentication or encryption**. There is no password validation or transport-layer security. Any client that can establish a TCP connection to the XRCON port has full command execution access to the engine console.
+
+The only security measures are:
+
+1. **Default localhost binding**: The server binds to `127.0.0.1` by default, accepting connections only from the local machine.
+2. **Disabled by default**: The `xrcon_enable` variable defaults to `0`, so the server does not listen unless explicitly enabled.
+3. **Privileged variables**: Both configuration variables are restricted to privileged users and cannot be modified through unprivileged console commands or external access.
+
+
+
+## Comparison with Legacy RCON
+
+| Feature | XRCON | Legacy RCON |
+|---|---|---|
+| Transport | TCP (stream) | UDP (datagram, out-of-band) |
+| Port | Configurable, default 27000 | Game port (default 27015) |
+| Framing | Binary frame header | Plain text over UDP |
+| Authentication | None | Password-based |
+| Max clients | 1 | Multiple |
+| Interaction format | Full console access | Request-response only for submitted command |
+| Supported environments | Client and server | Server only |

+# Static HTTP server list
+
+Replacement for the UDP `S2M_SCAN_REQUEST` / `M2A_SERVERSLIST` exchange
+described in [02-connectionless.md](02-connectionless.md). Read-only HTTP,
+no NAT punching, no filtering or pagination in the request.
+
+## URL
+
+`xashcomm.lst` carries a base URL per source:
+
+```
+masterstatic http://master.example.org/server-list
+```
+
+The engine appends `/v1/servers/<gamedir>` and `GET`s the result. For
+`gamedir = valve`:
+
+```
+GET http://master.example.org/server-list/v1/servers/valve
+```
+
+Trailing slashes on the base URL are stripped. Multiple `masterstatic`
+lines are allowed; results are merged.
+
+The request is bare: no body, no auth, no cookies, no compressed encodings.
+Only the standard `User-Agent` is set. `POST` / `PUT` / `DELETE` are not
+used; servers register out of band.
+
+## Response
+
+UTF-8 text, tokenized with `COM_ParseFileSafe` (whitespace separates,
+`//` and `#` start line comments, `"..."` quotes a token). One directive
+per record:
+
+* `ip <address>` — Xash3D server (protocol 49).
+* `gs <address>` — GoldSrc server (protocol 48).
+
+`<address>` is parsed by `NET_StringToAdr` (`1.2.3.4:27015`,
+`[2001:db8::1]:27015`, hostnames). Port defaults to `27015`. Unknown
+directives are skipped together with one operand so new keywords can be
+added without breaking older clients.
+
+`Content-Type` is not inspected, `text/plain; charset=utf-8` expected.
+
+### Example
+
+```
+# diffusion servers
+ip 192.0.2.10:27015
+ip [2001:db8::1]:27015
+gs 198.51.100.5:27015
+```
+
+A file with zero records is valid and represents an empty list.
+
+### Versioning
+
+The `/v1/` segment is fixed in this revision. A future protocol revision
+adds a sibling `/v2/...` resource without breaking older clients.
+
+## Client behaviour
+
+Each `ip` / `gs` record from the response triggers a probe to the listed
+address, identical to a server discovered through the UDP master. DNS
+errors, non-200 responses, and malformed bodies are reported to the
+console.
+
+## Server behaviour
+
+Any static HTTP server works. A typical setup is a periodic job that
+probes a set of known addresses and writes `v1/servers/<gamedir>`.
