+## 验收
+
+- 6900 inventory and provenance remain read-only
+- capability-family deduplication is reused
+- malformed, unsupported, hash-drift and false-completion input fails closed
+- Chromium, E2E receipts and completion overlays remain deferred

+- missing source or unsupported capability remains in_progress/blocked
