source'live' | 'ecb_daily' | 'fred_daily' | 'nbp_daily' | 'banxico_daily' | 'dof_daily' required

Public source enum — wire contract (D2). NO cached value (cache lives in X-Cache).

nbp_daily is the independent daily fallback for ECB/FRED reference gaps.

banxico_daily/dof_daily (added 2026-07-26) are the two official Mexican peso reference rates — both fetched from Banxico's SIE API (verified against banxico.org.mx), the only machine-readable source for either figure. They are Tier-C, active=False in the pair registry (never enter the USD-pivot rebase engine — pricing._legs skips inactive pairs) and are served only via the dedicated /v1/rate/usd-mxn-banxico / /v1/rate/usd-mxn-dof branch, never through /latest, /convert, or /range. See docs/DECISIONS.md D2/D9.

sourcesobject required
market_session'open' | 'weekend' | 'interbank_closed' required

Computed from a clock, no feed (D9). interbank_closed = a known non-weekend closure (e.g. an ECB/TARGET2 holiday detected via an empty Tier-C response — INGESTION §4).
