Low, mid or high distance from 50/50—not forecast quality.

Words & rules
member
One of the four Zeno30 AI forecasters (outside view, inside view, market anchor, red team).
f0
The team's combined forecast: a weighted average of the members.
sealed
Recorded and fingerprinted before the outcome. Protected values remain private until the declared reveal point.
locked
A submission is fixed and can no longer be changed.
closed
The submission window has ended; this does not mean the outcome is known.
resolved
The source has published the outcome.
revealed
Protected values are disclosed after resolution so the score can be reproduced.
confidence band
How far f0 is from 50/50: low, mid or high. Never the number itself.
warning
A candidate risk score above the fixed 10% floor—not a claim that failure is more likely than not. The live score is the highest member risk, not f0's failure probability.
bps
Basis points. 50 bps = 0.50 percentage points of interest rate.

Order follows Zeno's sealed rule . Candidate warnings are a testing signal and never change team weights.
