Runs — summary only

Finding. Under the stated rules (floor first, named credit, public tape, charge separate, third-seat refusal) recorded value appears and coins stay conserved.

Across the cases that were run, the share of existing acts that become visible sits near 28–36%, with a median near 32%. That share is the work that would not clear ordinary rails. It is not new money and not a mint.

A 3-month lower-income case (25,000 people) produced the same shape: smaller acts, higher floor pressure, coins conserved, gain near 30% versus regular rails.

Scale and demographic mix move the absolute numbers. They do not invert the pattern.
