ETK garage edition core (first release).
- GT5P road-flicker fix (upstream RPCS3 #11912): decode fully-zeroed CONTROL1 on 1x1 textures as ONE x4. Field-validated flicker-free on Adreno 650 (Daytona, Eiger, Fuji).
- VK cyclic-reference fixes (upstream 4fa3aaf2b lineage): texture_barrier for cyclic textures in attachment layout + MUTABLE_FORMAT_BIT on feedback-loop RTTs (disables UBWC on Turnip). Fixes menu diagonal pixel-garbage without Strict Rendering Mode.
- Icon-only shader-compile notification.
Base: ouroboros420/rpcsx rebase-rpcs3-jun2026 @ 678c28f. Target: arm64-v8a (armv8-a baseline), validated on SM8250 / Adreno 650 / Turnip 26.1.3.
Developed with Anthropic Claude (Claude Code) as the engineering side of the ETK garage; all changes field-validated on hardware by the human operator.
