Collaboration diagram for donner::editor::FrameHistory:

Public Member Functions
void	push (float ms)
	Append a new frame sample. The matching backendMs[] slot is reset to 0 ("no backend result this frame"); setLatestBackendMs fills it in if a render result lands during the same UI frame.
void	setLatestBackendMs (float ms)
	Record a backend (async-renderer worker) timing for the most recently pushed frame. Called by RenderCoordinator::pollRenderResult when a new RenderResult arrives. No-op if no frame has been pushed yet. Also updates lastBackendMs so UI elements that want to show the latest measured backend latency have a persistent value.
float	latest () const
float	max () const

Public Attributes
std::array< float, kFrameHistoryCapacity >	deltaMs {}
	ImGui frame delta per UI-thread frame — populated from ImGui::GetIO().DeltaTime by noteFrameDelta.
std::array< float, kFrameHistoryCapacity >	backendMs {}
	Async-renderer worker time (ms) per UI frame, aligned 1:1 with the matching deltaMs[] slot. Holds 0.0f for frames where no render result landed (the worker was still busy or nothing was requested); consumers skip zero entries so the graph doesn't drop to zero between drags.
std::size_t	writeIndex = 0
std::size_t	samples = 0
float	lastBackendMs = 0.0f
	Most recent non-zero backend sample, so latched-backend-latency readers (the numeric readout, sticky-line rendering) have something to show between render-result landings.
