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: Weekly — cost models recompute when inputs move (Monday refresh fleet, 11:00–12:30 UTC); values are stable between input changes.
Revision policy: Points change only through staged updates (market_data_staged_updates) with an audit log; the Pro export carries X-Corrections-Count.

Known gaps: Known-gaps review pending — the coverage boundaries above are computed and current, but the curator’s qualitative gaps assessment has not been written yet. We state that rather than inventing one.
