quantmodel — Implement ensure_ohlcv + ensure_macro (coverage check → fetch → upsert → return)

Objective

Implement ensure_ohlcv + ensure_macro (coverage check → fetch → upsert → return).

Notes: ensure_ohlcv/ensure_macro + coverage_* + offline fail-closed; local parquet/csv promote; 17 datastore tests pass. Findings: ensure-ohlcv-macro-t132.md. Landed on main as e114f13.

Approach

Reuses existing report research/findings/ensure-ohlcv-macro-t132.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.

Results

Key table from source report (preserved):

Piece	Path
`CoverageError`, `coverage_ohlcv`, `coverage_macro`	`backtest/datastore.py`
`ensure_ohlcv`, `ensure_macro`	same
Local promote (no network)	parquet → OHLCV; `fred_*.csv` → macro
Tests (hit / miss / offline / promote)	`tests/test_datastore.py` (17 total)

Conclusions and metrics are in research/findings/ensure-ohlcv-macro-t132.md; see detail page for preserved tables/metrics.
