` to set simulated time, and `/faketime off` to restore real-time clock. Persisted in `game_clock.state_file` (override with `GAC_GAME_CLOCK_STATE_FILE`). Affects login and heartbeats without altering OS system clocks or network timeouts.
-- **Cyrene Train Login Scene**: Operational via `LoginShow_UP` manifest and bound to animation finish events, rendering the white train, pink-purple sky, petals, and clean logout/re-login transitions. Details in [Login scene notes](docs/login-cyrene-investigation.md).
-- **Emergency Unstuck via GaC-Srtool**: The **Unstuck** button in the GM Command Console issues `POST /api/client/unstuck`, executing `UIManager.ClearWaitNetPacketFullScreenBlock()` on the next client heartbeat. Safely unfreezes UI blocks without clearing CW saves or fabricating gameplay states.
-- **Roster & Star Merging**: Automatic 3-copy star promotion for duplicate avatars, equipment binding and tracking from Preparation screen, and protagonist spotlight selection policies.
-
-### 🚀 Getting Started on Windows
-
-#### Requirements
-1. Windows with PowerShell and an internet connection for the initial build. The launcher validates the Go toolchain against the minimum version in `go.mod`; if missing or outdated, it prompts to automatically download, verify (SHA-256), and extract the official archive into `launcher.go_install.directory`.
-2. Prepare Client, launcher/proxy, and redirect dispatch to the addresses configured in `server.json`.
-3. For standard binaries, keep data files and the `resources/` folder in the project root. For standalone distribution, binaries under `for ship` bundle embedded runtime resources.
-4. Execute `run.bat` and select the desired menu option:
-
-| Option | Function |
-| :---: | :--- |
-| `1` or Enter | Build both servers, launch servers, and launch the game client |
-| `2` | Launch both servers from existing `.exe` binaries |
-| `3` | Launch SDK server only |
-| `4` | Launch Game server only |
-| `5` | Launch both servers from existing `.exe` binaries and start Gay Proxy |
-| `6` | Build both `.exe` binaries only |
-| `7` | Exit |
-| `8` or `stop` | Stop all project server processes |
-| `9` or `requirements` | Verify Go toolchain and prompt for automatic installation |
-
-SDK and Game servers launch in separate visible console windows displaying live logs. The interactive launcher menu closes automatically after 5 seconds while server processes remain running. Use `run.bat stop` or close console windows to terminate.
-
-### ⚙️ Configuration & Anti-Hardcoding Policy (`AGENTS.md`)
-
-`AGENTS.md` strictly prohibits hardcoding machine-specific paths, usernames, IP addresses, ports, or game deployment URLs directly into source code or startup scripts.
-
-Priority Order: **Environment Variables > `server.local.json` > `server.json`**
-
-- `server.json`: Central shared configuration across launcher, game server, and SDK server.
-- `server.local.json`: Local machine overrides (ignored by Git). Create by copying `server.local.example.json`.
-- `GAC_CONFIG`: Custom config path override.

+
+Honkai: Star Rail game server emulator implemented in Go, ported from `GaC-hkrpg-ps` and referencing [PearlSR](https://git.xeondev.com/HonkaiSlopRail/pearl-sr). It includes the Game Server, SDK/Dispatch Server, and REST API for [GaC-Srtool](https://github.com/CAtlas0784).
+
+The project is currently under active development, targeting Client **4.6.53 OS**. Command tables and recent handlers reference PearlSR commit `005d2c12db4781071f4b5b68e8f364587886a710` (see [protocol update documentation](docs/protocol-update.md)). Schema parity does not imply that every in-game feature is fully operational.
+
+### 🎮 Currency Wars (CW) — In Development
+
+- **Autochess Simulation Engine**: Ported from [Currency-War-SR by xaodev](https://gaytea.cod-algieba.ts.net/xaodev/Currency-War-SR), implementing encounter generation following supply nodes, difficulty/selection matrix, and mode/chapter/boss EXP progression while maintaining verified battle paths. Full audit details in [CW xaodev handoff](docs/CW-XAODEV-CLAUDE-HANDOFF.md) and [CW route continuation audit](docs/cw-route-continuation-audit.md).
+- **Time Simulation (FakeTime)**: In GaC-Srtool, use `/faketime status` to view current game time, `/faketime ` or `/faketime ` to set simulated time, and `/faketime off` to restore real-time clock. Persisted in `game_clock.state_file` (override with `GAC_GAME_CLOCK_STATE_FILE`). Affects login and heartbeats without altering OS system clocks or network timeouts.
+- **Cyrene Train Login Scene**: Operational via `LoginShow_UP` manifest and bound to animation finish events, rendering the white train, pink-purple sky, petals, and clean logout/re-login transitions. Details in [Login scene notes](docs/login-cyrene-investigation.md).
