123 checks across all 48 routes plus /api/docs, driven on a throwaway
copy of the live database with anonymous, member, leader, admin and
owner access; 0 failures. Calendar checks used 2036 probes against the
real store and left it at 32 objects. API.md records, per route, the
capability and what each request actually returned. tests/api_drive.py
is the harness and tests/api_doc.py regenerates the document from its
results, so the next approval run is a rerun, not a rewrite.
