Corpora

Every corpus behind the bipsearch API and MCP endpoint, grouped by category. Each row declares its own tier, coverage, and ranking semantics. The docs and status columns are both a dated snapshot taken when this page was built, not a live reading: a corpus shown as up stays up here until the site is rebuilt.
