Known primary-input helper differences¶

Native input_primary_is_down at 0x004460f0 is a pure held-state query that always checks mouse button 0 and the fire binding in both fixed player records; the second record also supplies the alternate keyboard binding in one-player configuration. The Python helper accepts a clamped one-to-four player count, checks only those supplied fire codes, and updates its shared pressed-state tracker. This is a port API generalization, not a literal recovery of the native helper.

Native input_primary_just_pressed at 0x00446030 uses a query-driven global latch over those same three sources. Its first held query returns true, a second query returns false even in the same frame, and only a full release rearms it; an open console bypasses the query without touching the latch. The Python sentinel uses _PressedState.pressed_cache, so repeated queries within one frame return the cached edge result. Current callsites query once per frame, but the helper APIs are not semantically interchangeable.
