- Coverage window
- 2017 (pre-window context) → 2026 (proj.) (40 rows)Computed from the backing series at page-render time — never typed by hand.
- History honesty
- Observations recorded as published; no archive backfill flag on this series.
- Cadence
- Event-driven — curated prints land when a dated public source publishes one (per-dataset cadence weekly → annual, see recommended_cadence). The market-data agent sweeps Sundays 02:00 UTC; prints that clear its validation gate (source-excerpt verification included) apply automatically, the rest queue for human review.
- Revision policy
- Points change only through staged updates (market_data_staged_updates) with an audit log; the Pro export carries X-Corrections-Count.
