Module: FirelandsShared (src/shared)

FirelandsShared is the lowest-level static library used by every other target. It holds cross-cutting utilities that must not depend on game services or persistence.

Responsibilities

Area	Path	Purpose
Config	shared/Config.{h,cpp}	YAML via yaml-cpp; env overrides FIRELANDS_AUTH_CONFIG / FIRELANDS_WORLD_CONFIG
Logging	shared/Logger.h	spdlog wrapper — always include via this header
Networking	shared/network/	ByteBuffer, WorldPacket, opcodes, wire codecs, WorldCrypt.h
Crypto / SRP	shared/Crypto.h, SRPConstants.h, BigInt.h	SRP-6a math for authentication
DBC	shared/dbc/DbcReader.cpp	Client .dbc-style binary table reader
Game helpers	shared/game/	Access levels, permissions, GM appearance, experience tables
TUI	shared/tui/	FTXUI helpers for interactive consoles

CMake

Defined in src/shared/CMakeLists.txt. Links OpenSSL, spdlog, nlohmann_json, yaml-cpp.

Compiled sources today include Config.cpp, network/SpellCastWire.cpp, dbc/DbcReader.cpp; many headers are header-only.

When to add code here

Add to shared only when:

• Multiple layers need the same utility
• The code has no MariaDB, Boost.Asio session, or domain aggregate dependency
• It is genuinely cross-cutting (wire format, config, logging, crypto)
