The binary branch of AuthorizationChecker.check rebuilt its options with a
fixed six-field object, silently discarding partialGraphContext (and any
other caller option) — binary checks denied grants the normal path
allowed. Now spreads all caller options through. binary-partial-parity
pins: partial grants above the threshold allow, below deny, persistent
wins over partial, and binary decisions agree with normal decisions on
the same overlay.
