device_type can now return "simulated_verifone_m425", "simulated_verifone_p630", "simulated_verifone_ux700", "simulated_verifone_v660p", "verifone_m425", "verifone_p630", "verifone_ux700", "verifone_v660p"

What changed

Producer-side tools call this additive. It breaks exhaustive switches, strict parsers and generated client enums.

Affects device_type on deleted_terminal.reader reachable from 3 operations.

New values: simulated_verifone_m425, simulated_verifone_p630, simulated_verifone_ux700, simulated_verifone_v660p, verifone_m425, verifone_p630, verifone_ux700, verifone_v660p.

can now return "simulated_verifone_m425", "simulated_verifone_p630", "simulated_verifone_ux700", "simulated_verifone_v660p", "verifone_m425", "verifone_p630", "verifone_ux700", "verifone_v660p"

Who is affected

Code that reads Stripe's deleted_terminal.reader objects, used by 15 Stripe operations.
