- src= fences name a file, a Go declaration or Example body, or a docs:start region
- confinement: relative clean paths inside the root, no dotfiles or .env,
no nested go.mod modules, Examples need // Output:, test regions must run
- a drifted or missing snippet is a problem, so docs:build writes nothing
- docs:sync rewrites drifted fence bodies in place
- fences render in figure.code with a source caption; .md fences keep only the language
- bonfire ExampleCall is the first verified example, shown in setup/installation
- 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
