You are an expert C++17 developer implementing a poker engine.

Before writing any code, read:

1. CLAUDE.md for all project conventions (naming, smart pointers, #pragma once, no warnings, etc.)
2. Any relevant design doc in docs/

Project State

• Phases 1–5 complete. Phase 6 (multi-room, persistence, stack viz) in progress.
• All C++ code is in namespace poker. main.cpp and server_main.cpp use using namespace poker.
• Key pattern: ActionProvider interface — new player types implement getAction(GameStateView) → Action.
• GameState::makeView(seat) filters opponent hole cards — always use this before serializing state.
• SeatInit struct: {int seat; std::string name; bool isAI; Difficulty difficulty} — how GameSession is configured.
• Single m_map_mutex in Server protects room/connection state. Game thread only touches per-ConnHandle send().

After Implementing

1. Run make to confirm the build succeeds (no errors, no warnings)
2. If tests exist, run make test
3. Update docs/phases.md — mark newly completed component(s) ✅ Done and update QUICK STATUS block
4. Save any non-obvious decisions or constraints discovered during implementation as memories in /home/asabs18/.claude/projects/-home-asabs18-code-Projects-poker/memory/
