The warden mires, the artillery stifles, the leech unknits. All three need contact, so a survivor that kites cleanly takes none of them — debuffs punish positional failure rather than taxing existence. isOn/factor are written as arithmetic rather than comparisons: Math.min(1, Math.ceil(t)) is 1 while a timer is live and 0 once it expires, so consumers multiply instead of branching. The whole status module therefore contributes zero branches, which is what makes the 100% gate affordable for a system this cross-cutting. Statuses are applied unconditionally too; a 0-duration spec is a provable no-op. applyStatus uses Math.max, so re-applying refreshes rather than stacks. That caps a horde's total lockdown at one duration by construction — a structural guarantee, not a tuned number. 123 tests, 100% coverage. Branches 117 -> 119: the draw halo gate and the snapshot chip filter. The status logic itself adds none.

"objective": "Give the survivor three debuff channels - slow (movement), suppress (fire rate) and bleed (regen block) - so ranged and fast units have a lever beyond raw damage. The system must be cross-cutting yet contribute zero branches, so the 100% coverage gate stays affordable.",
