NNNN — Title

WARNING

This RFC is draft. Under refinement — not the contract.

Summary

One paragraph: what this proposes and what changes if it lands.

Motivation

Problem solved. Why now. Concrete scenarios that are awkward/broken/impossible without it.

Detailed design

Full proposal. Enough depth for someone unfamiliar with the discussion to implement. Lua surface, error semantics, acceptance criteria. Fenced ```mermaid blocks render via vitepress-mermaid-renderer.

Drawbacks

Costs. Friction added, surface widened, footguns, migration burden.

Alternatives

What else considered and why rejected. Include "do nothing."

Open questions

Must be empty before draft → accepted.

Implementation notes

Optional. File paths, modules touched, sequencing constraints.
