Anatomy of a call

Every call carries five fixed fields. Nothing is free text — that's what makes a call falsifiable instead of arguable.

caliber — call
$ caliber submit
> asset $SOL
> direction up
> target $240.00
> deadline Fri 23:59 UTC
> confidence 58%
01
asset
The instrument. Tradable assets can carry backing; events cannot.
02
direction
up / down / flat — inferred from your target vs. the live price.
03
target
The specific level that defines true vs. false.
04
deadline
An exact UTC timestamp. After this, the call is terminal.
05
confidence
1–99. Feeds the Brier / Caliber score only — never a payout.

A backable call carries two more required fields — call_type (tradable / event) and caller_stake, the caller's own committed capital. See Caller stakes.
