- Drop unused `import json` from new test module (F401).
- Remove unused `# noqa: BLE001` directives — project ruff config doesn't
enable BLE001 so the suppressions were dead weight (RUF100 x3).
- Replace `×` (U+00D7) with ASCII `x` in console output (RUF001).
- Collapse seed-strategy if/else into ternary (SIM108).
- Use `enumerate(as_completed(...), start=1)` for completion counter
instead of manual `completed = 0; completed += 1` (SIM113).
- Run `ruff format` on touched files.
Pre-existing lint errors on master (PLC0415/PLR0915/SIM113 in unrelated
commands) are untouched — separate cleanup PR if desired. Net delta of
this branch over master: 0 new lint errors.
All 374 tests still passing.
