Every repo keeps its documentation in docs/*.md, next to the code. Git provides versioning and dates; the MR provides review and approval.

Aggregated pages show their source repo, the commit and the date of the last update. A page without provenance breaks the build.

Authentication, code review criteria, service runbooks and deploy processes — the content that belongs to no single repo.

Confluence keeps product content. Bridge pages link into this portal so nobody loses the thread.
