Merged main (agent 90, ANALYSIS_VERSION 17/18 after main's 15/16) and rebuilt the bridge, foveation and a32
libraries from source (deterministic, no local paths).
Fixes on top:
- a32 loader: apply DT_ANDROID_RELR relocations (Journey of the Gods crashed at start)
- VrApi bridge: vrapi_Get/SetTrackingTransform (floor-level tracking; Shadow Point's player was below the floor)
- a32: never submit an untracked default head pose (hold up to 100 ms, repair or drop); pose consistency per display
time; submit/tracking counters
- VrApi bridge: wait again when xrWaitFrame gives a display time in the refresh just submitted (the runtime rejected
the second frame with AlreadySubmitted; Journey of the Gods ran at ~120 fps on a 90 Hz display and the scene slid
and snapped back); pacing counters
- VrApi bridge: GLES re-entry polls events before reusing the kept session (a lost or exiting session is replaced, a
stopped one waits for READY)
- VrApi bridge: STAGE is the runtime's STAGE space (play-area centre and orientation, unchanged by recentering);
LOCAL_FLOOR keeps the head-based origin
- signer certificate: pick the certificate the SignerInfo names, not the first in the PKCS#7 block
- flat 32-bit apps keep the bridge (it isn't a VR-only fix)
- Frida gadget loads are stripped before translation
- launcher restart test fixed; native/.cache is no longer committed
- catalog: Shadow Point and Journey of the Gods work (headset, 2026-10-14; min_app 1.1.2)
Holding the Frame's menu button turned 32-bit (and other VrApi bridge)
games 90-120 degrees to the side. The bridge's app space is LOCAL plus
the head's yaw at the start; the runtime's recenter moves LOCAL to the
head, so that old yaw was applied again. On a LOCAL reference space
change (and on vrapi_RecenterPose, ignored before) the origin is taken
from the head again in the first frame after the change, and VrApi's
recenter count goes up. Owner-verified with Gunjack.
The upstream patches are regenerated against OVRPort 5e7df52 (they
were missing the FOV cache changes).

Gunjack (CCP, UE 4.10, Gear VR) quit after loading because AndroidMain compares
GameActivity.AndroidThunkJava_GetSignature() with the original signing
certificate, and then crashed in the Frame's runtime when it entered VR again.
a32 bridge:
- frame.a32_bridge: original_signature() = Base64.DEFAULT(SHA-1(signing
certificate DER)) of the original APK (META-INF/*.RSA|DSA|EC), stored as
assets/fp_a32_signature.txt for libUE4.so games (convert(), shared with
bridge/convert.py)
- the bridge loads it at activity creation and answers guest calls on the
method ID of AndroidThunkJava_GetSignature()Ljava/lang/String; with it
(replaces the unused hex/OpenSSL prototype)
VrApi bridge: after loading, Unreal leaves VR mode and enters it again on the
same GL context; the first frame of a second OpenXR session there aborted in
vrclient (CSharedSemaphoreLinux::WaitFromGPU from the GL binding's
PreBeginFrame). vrapi_LeaveVrMode now keeps a running GLES session and
vrapi_EnterVrMode reuses it for the same context (another context still gets
a new session; Vulkan unchanged). upstream-patches/runtime.cpp.patch updated,
libvrapi.so and liba32bridge.so rebuilt.
Verified on the Frame: headless launch test passes (72 fps after re-entry);
owner-verified in the headset.

32-bit-only APKs (Gear VR / Oculus Go games) are no longer "unsupported": the
recipe engine suggests frame.a32_bridge, which converts the APK with the
translator bridge (convert() shared with bridge/convert.py) and ships
liba32bridge.so / liba32rt.so / liba32stub.so (native/build.py --only a32).
FramePort:
- engine._a32: overport off (OVRPort is 64-bit only; the patch ships OVRPort's
loader chain + its 32-bit platform dispatcher, overport.ensure_runtime_lib),
only frame.a32_bridge/adapter/launcher of the frame patches, 64-bit-only
adapter settings dropped, device.text_input_window for Unity; such patches
are hidden in the UI
- analysis extra.headset (ANALYSIS_VERSION 9): quest / go / gearvr ->
"Gear VR" / "Oculus Go" platform + Steam tag; catalog `headset:` field
- expects_obb ignores Unreal's OBB-inside-the-APK (assets/main.obb.png)
- catalog: com.fallen.affected, net.mobilemischief.spunkydungeon
Bridge / translator:
- VrApi 1.31 + Unity 2019 (no-config EGL contexts, LOCAL_FLOOR/STAGE tracking
space), GL buffer mappings per buffer object (fixes a ~10 MB/s guest leak and
garbled vertices), Go controller mapped to the right Frame controller
- native_app_glue imports (ALooper/AInputQueue/AConfiguration/AAsset*) for
UE4 NativeActivity games (Gunjack: runs, then quits on its own APK signature
check, which FramePort doesn't defeat)
- debugging aids: A32_BREAK, A32_STRACE to logcat, lifecycle/LeaveVrMode logs
vrapi-bridge: honours LOCAL_FLOOR/STAGE, picks a window/RGBA8 ES3 config for
no-config contexts; upstream patch updated, libvrapi.so rebuilt.
Verified on the Frame: Spunky Dungeon (Unity 2019.2, OVRPlugin 1.46) plays at
72 fps; AFFECTED The Manor still runs.

32-bit ARM (armeabi-v7a) libraries run inside a normal 64-bit Android app on the
Steam Frame, without Android's native-bridge mechanism (no Lepton changes): each
libX.so becomes libX.a32.so plus a 64-bit stub, next to liba32bridge.so (the
translator + host glue) and liba32rt.so (a 32-bit static-PIE runtime with bionic's
libc/libm/libz/libstdc++ and a loader for the game's libraries). Guest and host
talk through hypercalls (SVC 0, r7 = 0x0a32xxxx).
Bridge (native/a32translator/bridge):
- JNI both ways: generated + hand-written JNIEnv/JavaVM, RegisterNatives and
Java_* exports through AAPCS64 -> AAPCS32 trampolines, handles for references,
arrays/strings shared when below 4 GiB, else copied
- NativeActivity glue, libandroid imports (weak, generated from imports.txt)
- GLES 3.2 + extensions + EGL: 996 functions generated from the NDK headers
- OpenSL ES output implemented in the guest, played through AAudio
- VrApi 1.x (Gear VR era) translated to the 64-bit VrApi -> OpenXR bridge,
including OVRPlugin 1.12's frame layout and its wrapped (app texture) chains
- controller input as Gear VR touchpad/back/gamepad events (UnityPlayer.injectEvent)
- convert.py: prototype of the APK conversion (FramePort patch to follow)
- PC harness with a fake JVM (32 checks, qemu or native) and an on-device test APK
Translator fixes found on the way: guest signals during blocking system calls
and in host code (Boehm GC deadlock in Unity's Mono), static-PIE start files and
PT_TLS/PT_GNU_RELRO bias, host fault chaining, stderr to logcat in bridge mode.
vrapi-bridge: OVP_HEADLESS_TEST=1 skips the wait for a tracked head (automated
tests without a worn headset); upstream-patches/runtime.cpp.patch updated.
Verified on the Frame (2026-10-10): AFFECTED The Manor (Unity 5.6 + Mono,
OVRPlugin 1.12) runs in the headset with picture and sound; controls in progress.

Python core + Flet GUI + CLI that turns the manual Steam Frame porting work
into a pipeline: scan dumps, analyze, suggest patches (overport + Frame fixes,
catalog of 34 verified recipes), build, static-validate, install over SSH via
a Frame-side agent, add Steam shortcuts with artwork, headless launch test and
log triage. Includes the native sources (FrameBridge adapter, VrApi bridge
patches, GL shim), prebuilt artifacts, docs (playbook, runtime notes) and a
parity harness (34/34 games reproduce the known-good builds).
