-- When the judge may next be attempted for this phase.
--
-- The retry was a fixed 10s sweep for 30 minutes: up to 180 full re-evaluations
-- of one phase. A verdict is not one request either — the evaluator is agentic
-- and loops up to MAX_TOOL_CALLS + 1 times, resending the whole growing history
-- each round. So one unjudgeable phase could issue on the order of 2,000 model
-- requests, and a transport error (which is billed — the request was processed,
-- only its response failed to decode) issued them for real.
--
-- That is most of why the z.ai weekly plan kept emptying with no mission having
-- obviously done anything expensive. Nothing recorded it, because usage_events
-- carries no provider or model column.
--
-- NULL means "attempt on the next sweep", so existing rows and the first
-- attempt of every new phase behave exactly as before.
