Proposition 6.2 (Endpoint-only escape). For $m\ge2$ , let $S_m=0^{2m}1100$ . Its longest even-palindromic suffix is $001100$ and the suffix link is $00$ . The mirror occurrence of $00$ ends at the historical prefix $0^{2m}$ , whose longest suffix-link chain is $0^{2m},0^{2m-2},\ldots,00,\epsilon.$ Recovering $00$ from that untyped endpoint takes exactly $m-1$ suffix-link steps.
