Research in progress
Observatory is preparing and verifying real benchmark data. Public numbers will be released only after that verification is complete. Placeholder and test results stay hidden until then.
Constructive reasoning
Program synthesis, invariant discovery, Horn-clause solving, and solver-guided repair.
