Module rendergraph 

Declarative render graph subsystem for the Proof Engine.

This module provides a frame-graph architecture where render passes are declared as nodes in a directed acyclic graph. Resource lifetimes are managed automatically, barriers are inserted between passes, and execution order is derived via topological sort.

Architecture

• graph — RenderGraph, RenderPass, ResourceNode, topological sort, cycle detection, conditional passes, multi-resolution, validation, graph merging, DOT export.
• resources — ResourceDescriptor, TransientResource, ResourcePool, aliasing, ImportedResource, version tracking, memory budgets.
• executor — GraphExecutor, PassContext, barrier insertion, GPU timing queries, triple-buffered frame timeline, async compute, execution statistics, hot-reload.
• passes — 12 built-in pass implementations for a full deferred rendering pipeline.

Modules

executor

Graph execution engine: walks sorted passes, manages barriers, GPU timing, triple-buffered frame-in-flight management, async compute overlap detection, execution statistics, and hot-reload from config.

graph

Declarative render graph: named passes, resource nodes, dependency edges, topological sort, cycle detection, conditional passes, multi-resolution passes, validation, merging, and DOT export.

passes

Built-in render pass implementations for a deferred rendering pipeline.

resources

Automatic resource management for the render graph.
