rc.1-rc.5 shipped a unified /infrastructure /workloads /storage
/recovery top-level layout; rc.6 reverts the frontend to platform-
shaped pages (Proxmox / Docker / Kubernetes / TrueNAS / vSphere /
Standalone) on the same unified resource backend.
Updates the shipped v6 release docs to match:
- RELEASE_NOTES_v6.md and V6_CHANGELOG.md rewritten to describe the
v6 layout as platform-shaped on a unified backend, with a paragraph
in each explaining the rc.6 revert and the operator feedback that
drove it.
- UPGRADE_v6.md prerelease packet pointer bumped from rc.5 to rc.6.
- MIGRATION_UNIFIED_NAV.md gets a top-of-file revert banner that
redirects bookmarks targeting the unified routes to their platform-
shaped equivalents; the original content is preserved below as a
Historical Context section so the 19 tracked references into that
doc still resolve.
Also adds the rc.6 draft packet:
- docs/releases/RELEASE_NOTES_v6_RC6_DRAFT.md
- docs/releases/V6_CHANGELOG_RC6_DRAFT.md
Validation SHAs in both drafts are left as <populate at packet
finalisation> markers; they fill in when the release-control packet
runs.
