Treat signed JSON version fields and CoMID tag-version as monotonic generations. Require local artifacts to meet the measured policySvn/MROWNERCONFIG floor without using wall-clock time. Compare peer JSON mapping and identity versions only against like-for-like local JSON baselines; CoRIM tag-version remains an independent namespace used only for its local floor. Update generation tooling while preserving newer artifacts and signer rotation. Fixes microsoft#198 Signed-off-by: Haitao Huang <haitaohuang@microsoft.com> Assisted-by: GitHub Copilot CLI:gpt-5.6-sol [migtd-review]
The proposal now distinguishes routine cumulative collateral releases from security-driven policySvn floor increases. It also documents that removing a historical MigTD hash prevents resolving init_servtd_info_hash, which can strand tenants from migration or rebinding.

Document all JSON RTMR2 redactions, the CoRIM-only measured shape, direct signer-anchor enrollment, and the monotonic freshness model. Remove references to the nonexistent CoRIM design document.

Summary
Dependency
Depends on #208. This branch includes the two #208 commits so the documentation remains aligned; its diff will shrink after #208 merges.
Closes #204
