/**
 * Session 7b pipeline regression test.
 *
 * Locks in the three fixes that unblock the live deploy:
 *   1. Body parser accepts payloads up to 10 MB (no more poller 413s).
 *   2. /api/grading/resolve still grades correctly with the raised limit.
 *   3. The orchestrator's grading output has the canonical shape:
 *      { id, grade, prop } for every prop persisted.
 *
 * Mocks every upstream (Supabase, distribution channels, intelligence
 * services) so the test runs offline.
