control/docs/ is the single canonical Project Memory. It is versioned,
reviewable, searchable with Git and rg, and changed through pull requests.
Stable architecture, contracts, ADRs, glossary, integration ownership, runbooks, and release rules belong here. Current work, decisions and evidence belong in GitHub Issues. Detailed repository-specific implementation belongs in the affected repository.
GitHub Pages may later render these files, but generated Pages is only a view. Do not create a GitHub Wiki or external Wiki as a second editable truth.
