PR0 readiness: Lambda1VR Steam Frame
Disposition: HOLD · EXPERIMENTAL · PRIVATE. The target is the private astromaddie/lambda1-vr repository. Do not confuse it with origin (astromaddie/Lambda1VR), an existing public repository, or Team Beef upstream. The 2026-10-11 audit records unresolved signing/machine-specific artifacts, assets/extras.pak provenance, and GPLv3 / Half-Life SDK terms compatibility; it does not provide a grant: PR0 audit.
Source identity and checkout evidence
- Repository: lambda1-vr; branch frame-dev; source HEAD at review:
4fb7428b9e. - Remotes: upstream is Team-Beef-Studios/Lambda1VR; private is the intended target astromaddie/lambda1-vr; origin is the distinct astromaddie/Lambda1VR repository and is not the target.
- Initial worktree had untracked .DS_Store, Projects/.DS_Store and Projects/Android/.DS_Store; all were preserved. No fresh clone was made.
- The previous root README is archived byte-for-byte at docs/README_PRE_PR0.md.
Platform and build route
Target is Steam Frame / Lepton Android 11, ARM64, SteamVR OpenXR and GLES 3.2; APK id com.drbeef.lambda1vr.frame. Build with JDK 17 and NDK 25.1.8937393 using cd Projects/Android && sh ./gradlew assembleFrame; expected output is Projects/Android/build/outputs/apk/frame/lambda1vr-frame.apk. The first build fetches and verifies Khronos OpenXR loader 1.1.63. The optional Frame menu tile needs assets/background/800_1_a_loading.tga from Team Beef's v1.7.4 release APK and Python Pillow/NumPy; the build falls back to the release tile if these are absent. No build, host test, package or device action was run for this documentation pass.
Historical evidence and limits
The architecture record reports earlier unattended SteamVR sessions: main menu at 72 fps, the first level c1a0 loading in both eyes, Steam Half-Life files read in place, and an unattended 2026-10-05 Steam-title run at 120 Hz / 2160 per eye. The 2026-10-05 wear was on an earlier build and the user reported a smooth 120 fps and a sharp image. There was no worn frame-time capture. The host binding test and synthetic button logs do not prove physical controller input. In-game laser sight was not visible in four unattended dumps; barney_vest, barney_helmet and sprites/scope remain missing. SteamVR-menu exit and full wearer workflows remain unverified. No historical result is presented as a test of this HEAD.
Game data and rights
Use a user-owned Steam Half-Life install on the Frame (steamapps/common/Half-Life/valve/liblist.gam) or place a retail valve/ directory at /sdcard/Documents/Lambda1VR/valve; Half-Life: Source is incompatible. The full retail installation must be supplied separately; assets/extras.pak remains under provenance review. The audit calls for cleanup/provenance review of tracked or historical Android debug signing material, local.properties and assets/extras.pak. Root/Xash GPLv3 and Half-Life SDK terms require a documented compatibility/separation or permission route before publication; upstream notices and game ownership do not resolve that.
Pending acceptance
From a clean, identified source snapshot, verify install as a persistent Steam devkit title; physical Frame button and pose input; both-eye stereo and head tracking; pointer-driven menus; actual first-level gameplay, weapon and flashlight actions; pause/resume; save/load across relaunch; SteamVR-menu exit and clean shutdown. Repeat the 120 Hz / 2160 run while worn and capture frame timing before making a performance claim. No current-HEAD build, headset or worn timing result is claimed.
