  We analyze the error correcting properties of the Sachdev-Ye-Kitaev model,
with errors that correspond to erasures of subsets of fermions. We study the
limit where the number of fermions erased is large but small compared to the
total number of fermions. We compute the price of the quantum error correcting
code, defined as the number of physical qubits needed to reconstruct whether a
given operator has been acted upon the thermal state or not. By thinking about
reconstruction via quantum teleportation, we argue for a bound that relates the
price to the ordinary operator size in systems that display so-called detailed
size winding of Nezami et al. (2021). We then find that in SYK the price
roughly saturates this bound. Computing the price requires computing modular
flowed correlators with respect to the density matrix associated to a subset of
fermions. We offer an interpretation of these correlators as probing a quantum
extremal surface in the AdS dual of SYK. In the large $N$ limit, the operator
algebras associated to subsets of fermions in SYK satisfy half-sided modular
inclusion, which is indicative of an emergent Type III$_1$ von Neumann algebra.
We discuss the relationship between the emergent algebra of half-sided modular
inclusions and bulk symmetry generators.
