API Endpoints & URL Reference

JSON Endpoints

`/api/stats.json`	Registry statistics
`/api/documents.json`	Index of all documents — lightweight rows linking to per-doc records
`/api/doc/{id}.json`	Single document by `docId` — full record including `$meta` provenance
`/api/mri-cite-map.json`	MRI inline-citation sidecar — refs known to MRI but with no registry doc (`resolvedDocId` or `cite` text per entry); used by the doc-page renderer and reference tree to inline `<cite>` blocks for MRI-only refs
`/api/schemas/`	JSON Schema for documents

All JSON responses include "$schema" and "apiVersion" fields for machine validation. Current API version: 1.0.0.
