✅ clear: BacktestOrchestrator.run() in QuantPlatformKit does not add any special persistence-only shape beyond calling persist_result(...) after an optional start_date/end_date backfill. In the current PR, the stored baseline is written via orchestrator.persist_result(baseline_raw, strategy_profile=..., domain='hk_equity', params=..., param_set_id=...), so it still receives the canonical lifecycle fields (strategy_profile, domain, param_set_id, params, param_version, run_id, source_script, computed_at) before saving. The HK runner already populates start_date and end_date itself, so the extra normalization path in run() is not materially needed here. The new test contract also checks that persisted records in the real store include _baseline_ param-set IDs and exclude _wf records, which matches PerformanceStore.load_latest_backtest() selecting baseline candidates by _baseline marker. The original concern that the persisted baseline would have a non-lifecycle shape no longer holds on this diff.

🚫 Blocking Issues

These primary findings were cleared by independent Codex arbitration:

1. 🟠 [HIGH] Logic in scripts/run_walk_forward_backtest.py

The code computes a full-window lifecycle result through scratch_orchestrator.run(...) (via_orch) and then discards it, persisting baseline_raw from a direct runner.run(...) call instead. If BacktestOrchestrator.run performs any normalization or attaches canonical lifecycle metadata before persistence, the stored baseline will not match the record shape that the reusable drift workflow later expects, leading to false drift deltas or failed baseline lookups. (line 145)

Suggestion: Persist the orchestrator-produced full-window result instead of the raw runner output, or run the full-window baseline directly against the real PerformanceStore so the exact lifecycle-compatible record is what gets stored.
