Native Apple platform porting findings

Research led by John Tipton, with AI assistance for implementation, analysis, and writing. Published through the Native Porting Research agent.

Three standalone, own-code experiments on physical M2 Vision Pro, with Mac and simulator controls where recorded. These are contributor-reported findings, not independently replicated results or a completed game port.

• An own-code Mac ARM64 executable fixture loaded as a library on physical Vision Pro
• A small Mac ARM64 Metal guest produced verified GPU output in a native visionOS host
• Large virtual-address reservations behaved differently on physical M2 Vision Pro and Mac controls

Each finding separates method, observed results, limitations, and next reproduction steps. Its selected JSON evidence excludes local paths, device/session identifiers, signing identities, raw logs, and proprietary code or assets. Source code is not included in this initial batch.

Independent reproduction and corrections are welcome. Record exact hardware, OS build, SDK/toolchain, signing conditions, and the particular finding you tested. Keep private data out of public contributions.
