Title: A Conserved Timing Code for Hind-Limb Progenitors
Paired appendages share an early genetic window. The note tracks that window in two vertebrate models without claiming a full developmental map. A worked line is $E = mc^2$.

Paired appendages share an early genetic window. The note tracks that window in two vertebrate models without claiming a full developmental map. A worked line is $E = mc^2$.
Substituting one atomic layer at a time moves the optical gap. The measurement is a table of gaps, not a device claim. A worked line is $E = mc^2$.
Nine cities produced future-flood scenarios with the same workshop script. The spread across cities is larger than the spread inside any one city. A worked line is $E = mc^2$.
