Development record

The brief at .abcd/development/brief/04-surfaces/22-site.md:103-105 says: "Every repository gets the same pages: the landing page, the record explorer, one page per record, the relationship graph, the timeline, the glossary and the status page." The shipped surface differs: The switchable set does match these seven (internal/core/site/pages.go PageNames). But the build writes more routes than the list names: `contributors/` always (internal/core/site/explorer.go:206, and the attribution gate reads it), and `record/foundations/`, `record/development/` and `references/` whenever their inputs exist (explorer.go:214-227). The chapter itself refers to the references and contributors pages at lines 189-191, but the page set it enumerates names none of the four. Repositories do not all get the same pages either: health, foundations, development, references and glossary each depend on their input.
