Readout Channel Entropy Bound
S_vN(ρ_out) ≤ log(dim H_∂) < S_BH. The readout Hilbert space H_∂ is a proper subset of the full ontic Hilbert space. The readout channel cannot carry away full ontic information content.

Claim boundary
This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.
Curation rationale
- physics-facing terms: entropy
- result-facing terms: bound, readout
- theorem/proposition-class item appears externally legible enough for standalone review
Review notes
