Option.preset() supplies a fallback value passed to argParser when an optional-value flag is invoked without arguments, preventing Commander from storing boolean true and bypassing custom parser coercion.
opts() contains boolean true instead of a parsed number when an optional-value option lacks a preset and is passed without an argument
opts() retains the default value when the optional-value flag is omitted entirely
opts() contains the parsed custom argument when the flag is passed with an explicit value
accumulating option collectors append preset values on valueless flag invocations instead of having the entire accumulated array overwritten by boolean true
options configured with choices validate against preset values rather than assigning boolean true outside the allowed choices list
