Meta-Universe 2.1 Working Draft — Portable Data Bindings

MMAS 2.1 introduces portable DatasetBindings across package trees, filesystems, Git, databases, object stores, HTTP and MCP. It adds typed Markdown and safe HTML profiles, deterministic traversal/query plans, CoverageProofs, separate semantic/package fingerprints, JSON Schemas, golden examples and CI validation. The design was independently reviewed by Claude and Grok; findings on mastership, snapshots, typed digests and package-tree coverage were incorporated.
