Add ConstraintDistance (outdoor/indoor start=10/5, max=50/20), byte-decoded from the matching retail binary (GetStartConstraintDistance 0x0050ebc0, GetMaxConstraintDistance 0x0050ec10 - both x87-return functions BN elided). Deliberately omits the vestigial player-vs-remote branch the disassembly shows loads identical constants either way. Pins the ACE-inversion (ACE's start mapping is outdoor 5/indoor 10, the opposite of the binary - the binary wins). Adds a full-chain conformance test proving an armed, over-strained leash actually blocks jump_is_allowed (0x47), not just the bare stub-property regression already covered. See docs/research/2026-07-30-constraint-leash-constants.md.
