REAL-WORLD-SCHEMAS-06: RFC with a rejected-alternatives section

What it demonstrates

A richer single type using recognized-relative order and a mandatory Rejected alternatives section.

Builds on: REAL-WORLD-SCHEMAS-02: Type the ADR frontmatter

How it’s done

The declarative YAML artifact, verbatim — no code required.

frontmatter:
  fields:
    status: { enum: [draft, review, final] }
body:
  order: recognized-relative
  allowUnknown: true
  sections:
    - section: Summary
    - section: Motivation
    - section: Detailed design
    - section: Rejected alternatives
    - section: Open questions
      optional: true

Surfaces exercised

• body.order: recognized-relative; allowUnknown: true; an optional section; enum frontmatter
• an absent required section -> structure/section-missing
