quantmodel — Inventory strategy data deps + design ensure

Objective

Inventory strategy data deps + design ensure_* datastore API.

Notes: Findings: ensure-api-inventory-t131.md + JSON. 102 runners, ~58 ETF tickers, 18 FRED ids, proxy/pre1980 paths, AS blob gaps, proposed ensure_ohlcv/macro/universe/as_returns/as_alloc + offline. NEXT: t132 implement ensure_ohlcv+ensure_macro.

Approach

Reuses existing report research/findings/ensure-api-inventory-t131.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):

Table	PK / keys	Purpose
`meta`	`key`	`schema_version`, `initialized_at`
`instruments`	`ticker`	OHLCV provenance: `source`, `updated_at`, `start_date`, `end_date`, `n_rows`
`ohlcv`	`(ticker, date)`	Daily Open/High/Low/Close/Volume
`macro_series_meta`	`series_id`	Macro provenance + span
`macro_obs`	`(series_id, date)`	Float observations
`as_artifacts`	`(kind, key)`	Opaque AS scrape blobs (`content`, `content_type`)

Conclusions and metrics are in research/findings/ensure-api-inventory-t131.md; see detail page for preserved tables/metrics.
