- Remove IsSignaled() from RHIFence interface (semantic inconsistency) - Remove Reset() from OpenGL implementation (no D3D12 counterpart) - OpenGL Fence now uses single GLsync + CPU counters for timeline simulation - OpenGL Fence Initialize() now accepts uint64_t initialValue (was bool) - Add comprehensive timeline semantics tests for all backends: - Signal increment/decrement scenarios - Multiple signals - Wait smaller than completed value - GetCompletedValue stages verification - Update documentation to reflect actual implementation
