# E37 public truth

What can be said: E37 is a library-level federation protocol between two sovereign domains, run in one
process. It has 30/30 modelled attacks blocked, 30/30 executed invariants, 10 races (exhaustive plus 100
seeded schedules each) with no execution lacking a currently valid local authorization, and a same-author
clean-room verifier that agrees on every test vector. Execution goes through a separate-process tool with
single-use tokens.

Out of bounds (no evidence): deployment claims, operation across real organizations or a network, any
third-party verification claim, standard status, legal protectability, monetary value. Scale figures are SIMULATION.
