Return expiring private download URLs for a stored result's raw datasets, so any
client (Google Sheets/Gemini, quants pulling data into their own stack) can fetch
the underlying numbers. Reads the STORED result only - the same figures shown on the
Helvetic dashboard and audit bundle; nothing is recomputed.
backtest_id: from run_backtest, run_quant_research, run_universe_research,
run_custom_ohlcv, run_custom_signal, run_custom_portfolio, or analyze_track_record.
datasets: 'all' (default) or a comma-separated subset of:
trades - the full trade / rebalance log (CSV + JSON)
daily_series - portfolio value, daily return, and drawdown per date, plus the
benchmark curve when stored (CSV + JSON)
metrics - the full metric set plus strategy assumptions and cost bridge (JSON)
Downloads are short-lived private links (they expire like report downloads) and are
scoped to the caller's own result - another account's data can never be returned.
For the always-available, never-expiring downloads, open the result page on the
dashboard. Pair with export_audit_bundle for audit-grade reproducibility evidence.
