Based on my review of the document, **there are no formal proposals** explicitly marked with "Proposal" (numbered or unnumbered) in this 3GPP contribution.

The document is marked as "Document for: Information and discussion" and presents observations about non-bit-exact conformance of metadata output in IVAS. While Section 3 (Conclusion) discusses expectations and invites discussion, it does not contain any formally stated proposals using the standard proposal format.
