DiscordPresence.dll — loaded by VanillaFixes; reads WoW 1.12.1 character state read-only, writes the status snapshot, and starts the companion from its worker thread after WoW startup.
DiscordPresence.exe — invisible companion that only reads the status file and talks to Discord IPC. It no longer launches WoW.

The normal game launch path stays unchanged:

Play Modernized WoW
  -> VanillaFixes.exe WoW_Modernized.exe
  -> WoW_Modernized.exe
  -> DiscordPresence.dll
  -> DiscordPresence.exe

The OctoWoW Discord Application ID is built into DiscordPresence.exe:

1544072796098011176

No manual Application ID setup is required. Advanced users may optionally create a discord_application_id text file to override the built-in ID.

Runtime data is stored under:

<WoW folder>\.modernization_tool\DiscordPresence\
  discord_wow_status.json
  discord_broadcast_flags
  DiscordPresence.log
  discord_application_id   (optional override)

The companion is never launched from DllMain; it is started only from the DLL worker thread after the startup delay. The DLL never performs Discord IPC, and the companion never reads or writes WoW memory.

OctoWoW race mapping

For OctoWoW, the helper treats:

race id 9 as Goblin / Horde
race id 10 as High Elf / Alliance
race id 16 as a High Elf / Alliance compatibility fallback

The companion reads the race field from discord_wow_status.json and includes it in Rich Presence details, e.g. Lvl 1 Priest · High Elf · Alliance.

Independent sampler implementation

The WoW memory sampler is implemented in this repository with its own internal organization. It preserves the existing runtime contract (same status JSON, broadcast flags, timings, read-only memory access, and exact-PID companion startup) so DiscordPresence.exe does not need to change.

The client addresses/field offsets are compatibility data for WoW 1.12.1 build 5875. IchaLaunch remains credited as an earlier Rich Presence implementation that inspired this integration; its source code is not bundled here.
