title: Databento GC Contract Mapping for Backtests
status: backlog
priority: P1
effort: M
depends_on:
- DATA-DB-001
tags:
- databento
- futures
- backtests
summary: Add real Databento futures contract mapping for GC backtests so the page can support gold futures without fail-closed restrictions.
acceptance_criteria:
- Backtest-page Databento runs support GC without requiring users to know raw contract symbols.
- Contract selection or front-month rollover rules are explicit and test-covered.
- The selected contract path yields non-empty historical price data for supported windows.
- Browser validation confirms the GC path works from `/{workspace_id}/backtests` with no visible runtime error.
technical_notes:
- Current hardening work intentionally fail-closes GC on the backtest page because the raw `GC` symbol does not resolve reliably in Databento historical requests.
- Follow-up work should decide between explicit contract selection, continuous mapping, or deterministic rollover logic before re-enabling GC in the Databento path.
