What this PR does

One paragraph. What changed and why.

Linked Issue

Closes #___ (required for anything that changes an ID, introduces vocabulary,
adds a pattern, or proposes a gap — per CONTRIBUTING.md).

Type

• New pattern (must include diagram, runnable example, and anti-pattern)
• New gap (must include reproducible scenario and heuristic / trust-stage ref)
• Teardown (must use agent-ux-teardowns/_template/ and pass schema validation)
• Framework edit (must include rationale, ID migration note if renamed, updated examples)
• Schema fix
• Doc fix / typo / link
• Other (explain)

Contribution bar — checklist

Per CONTRIBUTING.md:

• I've read CONTRIBUTING.md.
• If this introduces or renames an ID, I opened a debate Issue first.
• If this adds a pattern, it has a diagram, a runnable example, and an anti-pattern.
• If this adds a gap, it has a reproducible scenario and references a heuristic or trust stage.
• CI passes (schema validation, link check).
• No emoji in code or schemas.
• Short sentences. Named things over adjectives.

Out of scope
