A1-CIDAH standard and this site's status
Returns the eight clauses of the A1-CIDAH specification together with this site's measured status against each one.
News desks
Lists the news desks. With a slug, returns that desk's current items, each with provider, time, direct link and the display permission that travels with it. Returns a HOLD instead of items when no verified feed is available.
Current battle record
Returns the current battle: competitors, every trade with its entry and exit, equity snapshots and the window state. Trading truth is read from the record's own truth field — PAPER unless it carries LIVE. Returns a HOLD when there is no fresh verified record.
