development.md was a bare link list whose 'implementation guides'
blurb still taught the pre-RLS visibility pattern. Now it's the
developer-tier portal: contributing/development.md as the start-here
(architecture/setup/testing — fresh and maintained), the gated API
reference with its per-area entry points and the openapi.yaml mirror,
the four protocol docs, the under-the-hood guides (RLS visibility,
scanner sidecars, calibre OPF, tag-normalization contract, Android
design), the standards (writing-ui-docs, glossary, contract pins),
and the gates enumerated — routes<->docs, Bruno parity, links, labels,
RLS invariant. writing-ui-docs.md's Developer-tier line closes the
open tone question: how-it-works, source-pinned, external software
linked not paraphrased.
