double_conv Design

Use this page to explain the structural responsibilities and implementation constraints of this module. double_conv in Luna-Flow/quaternion.

Responsibilities

• Keep the code and docs aligned around src/double_conv.mbt.
• 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.
