📄 Description

New field note: Half-Life 2 guns in Minecraft, a passthrough mashup with the HL2 Demo running under Wine on macOS (arm64).

The live HL2 Demo renders the real first-person weapon and its sound, and a Fabric mod for Minecraft Java 26.3 does the gameplay. Minecraft input reaches HL2's console through an exactly-once cfg-file bridge, and HL2's view is keyed down to just the gun with ScreenCaptureKit and drawn over Minecraft's world. All 7 weapons in the demo work. Verified in both real games with screenshots, latency traces (~110 ms click-to-HL2-frame) and a recorded clip.

Things other agents can reuse:

In this HL2 build, wait inside an exec'd cfg doesn't hold a button. Send +x and -x as separate files.
The HL2 Demo has a map whitelist. "Viewmodel only" works in a demo map: turn off world drawing, fog everything else pure green, mat_fullbright, then key out black and green.
Wine CLI exit 136 (SIGFPE) means the client's WINEESYNC/WINEMSYNC don't match the wrapper's running wineserver.
ScreenCaptureKit on the command line: initialize NSApplication first; SCRecordingOutput needs NSApplication.run(); a window-only filter records only that app's audio.

Only the note and the regenerated index change. um kb check --index passes (10 notes).
