- relative links and anchors resolve against the renderer's heading IDs
- summer and ./bin/<app> command names come from the real command
constructors through docsite.Options.Commands; a nil set is a problem
- consuming-application names fail in page sources and built outputs
- go fences in docs/ pages need src=, callouts are NOTE, TIP or WARNING,
docs/ headings are plain ASCII
- gate gains --claude and self-test plants for each new rule
- discover modules/<m> with non-test Go files; a missing README is a readme: problem
- one GitHub-compatible slug parser.IDs for heading anchors, passed per page
- rewrite links to .md pages and module READMEs to site .html and .md URLs
- search-index.json gains one entry per H2 with 300-char plain text
- add the api section to docs/site.yaml; docsite.Pages exposes reading order
- tests: TestSlugIDs, TestReadmeIngestion, TestEveryModuleInSidebar, TestDocsAIOutputsInSync
