  "body": "CURRENT SPLIT WIRING RED (no-excuse remains clean): prepare imports stale private names from helpers. Exact mappings from helper symbols: `_changed`→`changed_paths`, `_migration`→`migration`, `_rollback_rehearsal`→`rollback_rehearsal`, `_validate_candidate`→`validate_candidate`, `_write`→`write_receipt`; update callsites. Test imports `clean_boundary` from execute but it now lives in `nutricoach_v150_live_upgrade_boundary`; concrete_host same. Execute has unused `tree_snapshot`. Format exact new files. Then run pytest/Ruff/based/ty/no-excuse simultaneously. No structural change beyond wiring.",
