## Additional Hard-Fail Supporting Trace

- `ty6aQD9O0LnTvg` (Wave 16 export debug):
  - `time_scope = 2023-07-06` for a July 2020 settlement scenario.
  - `live_mcp.matched_rows = 0`, `returned_rows = 12`.
  - problem-unit lifecycle domain: `customer_settlement:9`.
  - evidence refs include out-of-window years (2023/2025/2026/2030).
