ADA requires a shower dam to be no greater than
0.5 inches. When installing PVC or CPE liners,
where does one terminate the liner? Any
preferences for CPE over PVC?

Ah, ADA, the horrors...
Okay, so you have slope to the drain inside the stall, yes? At the curb, which may or may not be at the same elevation--it may be higher, resulting in a reverse slope--as the floor outside the stall, is the highest point of the slope towards the drain. From this point out from the stall, I usually extend the pan 24". I then tack the end of the pan down to the subfloor with UltraSet, if on slab; butyl if on wood.
Makes for a tight seal to the subfloor. Of course, this is all recessed/depressed below mud mortar bed.
This is just one area where it is glaringly obvious that ADA is vaguely written, but strictly enforced.
