The question
Which mechanisms implement informative reporting and differentiated search under budget balance, collusion, and private-action constraints?
What we found
- DD-C-0048: In the nine registered two-agent score-difference mechanisms, all realized transfers are exactly budget balanced; each positive-coefficient regime makes truthful reporting with direct action a weak pure Bayesian Nash equilibrium with discovery probability 8/9, and none makes that profile strict against every joint report-action deviation.
- DD-C-0050: Across all 123 registered regime-and-transfer rows in DD-006A's normalized linear class, 31 weakly implement truthful reporting and the declared differentiated recommendation for both fixed tie roles, but none strictly implements it; the exact maximum all-tie strict margin is zero.

preserve DD-006A's zero-strict boundary and DD-006B's subsidized strict frontier; broader equilibrium or transfer classes require a new registration
