Sideways 45 was the first frozen mixed-sideways branch.
It showed how a useful idea could fail once the rules were locked and tested more broadly.
That makes it a clean reference point for the later work.
Full session

Frozen rule set. Mixed-sideways logic, fixed entry, fixed risk.
What it showed. Good-looking stretches, not enough durability.
Why it stayed. A comparison point for the later tick work.
