The clone's moving-flipper gate used the cross-product operands in the
opposite order, mirroring and narrowing the hit wedge. Right-flipper release
also used record 81's first endpoint even though the original reads its second
endpoint. Correct both geometry paths, retain the recovered swept tip bounds,
and add live-binary boundary vectors plus a dense transition regression.

Add a bit-exact six-byte Real48 implementation for integer conversion,
rounding, comparison, add/subtract, multiply/divide, and Newton square root.
Use the normalized Borland random-register result and route speed clamps,
segment/circle detection, moving flippers, captures, triggers, and magnetic
fields through the recovered arithmetic instead of host floating formulas.
Preserve Real48 spin per ball and feed it through the original tangent/spin
response, separating zero-spin C fixtures from retained-spin Wine traces.
Replace path-progress selection with surface-distance ordering and implement
dynamic records 174/175, including impulse transfer to the other slot,
normal_velocity-1000 response, and the second post-collision speed clamp.

Remove the live-fitted upward and downward flipper polynomials. Port the
reconstructed 1000:7ed9 path with delta-specific pivots and record edges,
integer cross-product and radius gates, penetration, response-record gain,
wrapping velocity updates, and the final position delta.
Use resting records on press and the already-raised records on release, correct
the original delta direction, and apply each edge to both live ball slots. Keep
render-facing Vec2 projections, but adjust their float representation by ULPs so
every gameplay millipixel round-trips exactly instead of losing reconstructed
integer results.
