This validates the offline handoff for one captured instant; it does not claim live camera tracking, material parity, or an original-frame pixel comparison. +For visual regression work, `fparkan-game --backend static-vulkan` also accepts +`--readback-out <path>`. It writes the final synchronized Vulkan readback bytes +only after the renderer has completed its normal teardown evidence; the JSON +report records the raw Vulkan format, byte count, hash, and requested path. A +three-frame diagnostic AutoDemo run wrote 7,372,800 bytes at format `50` +(`VK_FORMAT_B8G8R8A8_UNORM`) with the same frame hash reported by the renderer. +The artifact is a Vulkan-side comparison input, not an asserted original-frame +image. + The first bounded launch showed that repeated fingerprinting, rather than Vulkan initialization, was the load-path bottleneck: each new MAT0/TEXM request re-opened an already decoded archive and re-hashed its entire source file. |
