 152/-- **Physical Interpretation**: In Recognition Science, finite resolution
 153    corresponds to the 8-tick atomicity. The number of distinguishable
 154    states in any local region is bounded by the number of ledger updates
 155    that can occur in that region.
 156
 157    This is not an approximation or limitation of measurement—it is a
 158    fundamental feature of reality as described by recognition geometry. -/
