+# BriefLoop Demo
+
+This Space is a small public-facing demonstration surface for BriefLoop.
+
+It shows the product shape of a BriefLoop run:
+
+- source-backed claims
+- claim ledger
+- quality gates
+- audit trail
+- final reader-facing brief
+
+This demo is intentionally bounded. It does not run the full BriefLoop runtime,
+does not prove semantic truth, and does not claim output-quality improvement.
+
+Main project:
+
+- Website: https://briefloop.ai
+- GitHub: https://github.com/Stahl-G/briefloop
+- PyPI: https://pypi.org/project/briefloop/

+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
