## Executive Summary

This is a public-safe demo of the BriefLoop workflow shape. It shows how a
brief can carry a claim ledger, quality gates, and audit-oriented records.

## What This Demo Shows

- Claims are recorded before delivery.
- Warnings and blockers are visible.
- Reader-facing output is separate from audit/control artifacts.

## Boundary

This demo does not prove semantic truth and does not run the full multi-agent
workflow inside this Space.

|---|---|---|
| reader-clean | pass | No process residue in reader-facing output. |
| unsupported-material-claim | block | Unsupported material claim must be repaired or removed. |
