It logs `Dynamic tool loading: seeded ${n} tool reference(s) to ${k} deferred tool(s) the previous process sent` and is wired into the query-preparation path, guarded by `Oe.readsTranscriptRecord`.\n\n- Area: Tool Loading\n- Names: `defer_loading`\n- Tier: Under the hood\n- Useful: 3\/5\n- Signal: 3\/5"}
