CHANGELOG.md: new 2026-08-18 entry for today's work, plus a post-split
note explaining the branch-tag convention no longer applies (this repo
is now LithosAnanke-only, master as sole production line).
docs/lithosananke/ROADMAP.md: M7.1 section predates all the real
Tripod/Stadium/ACL work and was silently stale -- added a dated
redirect to FABRIC.md/FABRIC-2.md (matching the doc's own existing
pattern for the M8 section) rather than rewriting the whole section.
