Internals

The source code is the source of truth for internal design. Development assumes AI agentic coding. AGENTS.md is the entry point.

Architecture

Design rationale for each subsystem — what each layer does and why.

• Crate structure
• Computation graph
• ChainRules AD traits
• tidu AD engine
• End-to-end AD pipeline

Specification

Normative specs — trait signatures, op semantics, backend contracts.

• Primitive catalog
• Backend contract
• AD contract
• Optimizer passes
• Tensor semantics
