CodxLib 1.5.0

This file is for Forge 26.2. Every loader ships the same CodxLib version, so the notes below apply here too.

/codxlib help now also writes a .mrpack. Drop that one file into the Modrinth App (Add instance → From file) and it rebuilds the instance the report came from: same Minecraft version, same loader, every mod it can find on Modrinth, the codx mods' settings, and a world on the same seed. "It crashes on my world" becomes a single attachment.

• The world travels as settings, not terrain — only level.dat, so Minecraft regenerates from your seed. A few kilobytes, and nothing you have built is in it.
• Mods that aren't on Modrinth (CurseForge-only, private, self-edited) are listed in the pack's codxlib-debug/README.txt to add by hand, never dropped silently. No jars are copied in.
• /codxlib pack writes just the modpack. Same permissions as /codxlib help.

Developers: new CodxInstancePack.writeAsync(server) and CodxLib.gameDir() / IPlatformHelper#getGameDir() — a mod shipping its own IPlatformHelper must implement it. Nothing else from 1.4.x changed; raise your range to [1.5.0,) only if you use the new API.
