Oracle Gradient
The computed vector from your current performance toward the unobservable optimum in a domain's performance space. You never reach the oracle. You approach it. Each measurement sharpens your estimate of where it is.
Why It Exists
In every domain, there's an ideal performance point you can't directly observe. The oracle gradient gives you a direction to move even when you can't see the destination - it's the operational derivative of the Performance Frontier.
Rosetta Stone
Four circles, four readings of the same object. Each role reads the artifact through its own lens.
A directional signal even when the destination is unknown. You cannot underwrite "how far from optimal"; you can underwrite "moving toward optimal." The gradient is bankable.
The answer to "are we getting better?" even when "best" is not defined. The direction is what you manage; the destination reveals itself through approach.
The performance delta between your current best and the frontier sample. Concrete, measurable, pointed at a target.
The operational derivative of the Performance Frontier. Under regularity conditions it exists and points toward a local supremum. Iterative improvement along the gradient converges; the rate depends on curvature.
