What this part means
The expressions on both sides represent the same quantity under the stated assumptions.
Its job in the formula
The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula
That motivates two access models. The global algebra score permits the optimal measurement on the entire declared horizon state. The causal collector score restricts the measurement to the world tube and duration of a modeled interior receiver. Their difference is an access gap, . This gap is another proposed observable. It prevents the phrase “information is in the horizon state” from becoming “one observer can gather it.” The global score is a capacity statement; the collector score is an engineering task constrained by causal geometry.
