! test_sovmetaagent.f90
! SovMetaAgent Integration Test Suite
!
! Five comprehensive tests:
! 1. Unit: SovMetaSearch returns sealed payload
! 2. Unit: Knowledge search filters by relevance (MLIR scorer)
! 3. Unit: Follow-up queries generated correctly
! 4. Integration: Agent → SovMetaSearch → WORM → Agent reads result
! 5. Security: WORM seals verify with Blake3+Ed25519
!
! Standard: Fortran 2018
! Build: gfortran test_sovmetaagent.f90 -lsov -o test_sovmeta
