// #3 fix — POST /projects/:projectId/documents must be registry-aware.
//
// A documents widget bound to a CUSTOM registry (e.g. the public space's
// _registry, whose folder_path doesn't match the project default) passes
// `registry_table_id` explicitly. The create handler must then:
//   1. resolve THAT registry row directly (not project_id + folder_path LIKE),
//   2. authorize against the registry's OWNER project, not the URL :projectId,
//   3. insert the document_content table under that owner project + folder.
//
// We mock _helpers.js so no live DB is needed — the assertions target the
// branch logic that is the actual bug fix (read/write registry asymmetry).
