📄 Description

Two field notes, the first Borderlands / UE3 entries in the knowledge base.

1. games/borderlands-2/bl3-weapons-and-movement-in-borderlands-2-willow2-sdk-mods.md

What it covers: Borderlands 2 (Steam, CL 2863302) with the Willow2 Mod Manager v3.8 (pyunrealsdk). Two Python SDK mods bring BL3 mechanics: all 8 manufacturer traits, anointments, slide, mantle and ground slam.
Verification: every feature was checked by the human in game, with the agent reading unrealsdk.log.
Key findings:
- Live part swaps via InitializeFromDefinitionData.
- A per-shot firing-mode override.
- Real shots from any actor via WillowWeapon.Behavior_Fire.
12 gotchas, including:
- SDK-side traces and LOS always report blocked;
- direct TakeDamage with the Melee source hangs the game;
- damaging while walking PawnList hangs the game.

2. techniques/reading-ue3-gearbox-games-offline.md

How to read exact UnrealScript function signatures from LZO-compressed cooked .upk files (pure-Python LZO1X, export/property flags).
How to decode Gearbox BehaviorProviderDefinition graphs (event/behaviour links, variable links, CompareFloat output ids).

Both checked with um kb check; index regenerated with um kb index.

no game files, decompiled code dumps or secrets (game symbols named only; the mods themselves are not published)
versions and verification written down
