/**
 * FULL RUN (2026-09-30) - shared library. Imports the pilot's lib-common / lib-prompt read-only and
 * does NOT change any pilot file. What it adds:
 *   - the fourth test (Multiple Intelligences, 40 items, same 5-option scale) registered into the imported
 *     TESTS object at runtime (the pilot's own scripts never see it: they run in their own processes);
 *   - the 16-row model table (13 API rows: Bedrock + Vertex; 3 subscription rows: claude -p / codex exec);
 *   - its own ledger + responses (runs-full/), its own caps, both STOP files, heartbeat status.json;
 *   - the gate on the IQ rerun's live 47-probe-run processes (read-only process listing, nothing else).
 * Spend = logged tokens x list price x 1.15. Not an invoice (no billing access).
