integration Design

This subsystem owns adaptive and non-adaptive quadrature paths, shared error codes, and workspace management.

Responsibilities

• Keep the code and docs aligned around src/integration.
• Preserve the real execution model instead of smoothing over important internal differences.
• Note extension points, invariants, and limitations that maintainers must keep stable.

Maintenance Notes

• Update this page whenever the module boundary, core algorithm, or observable semantics change.
• If the module is intentionally incomplete, say so here instead of documenting speculative APIs.
