 Nested layers at an essential singular endpoint

Multiplication by $x^2$ makes this example exactly integrable once: $ϵx^{2}y\prime +(x^2-2{ϵ}^3)y=C$. Its homogeneous solution is $\exp (-x/ϵ-2{ϵ}^2/x)$. A solution with $y(1)={ϵ}^3$ that remains uniformly bounded needs $C\sim {ϵ}^3$, hence $y(0)\sim -1/2$. The scales $x=O(ϵ)$ and $x=O({ϵ}^2)$ connect the small outer solution to the order-one endpoint value. Bounded homogeneous contributions remain invisible to algebraic matching at the right boundary.
