 | 2025-12-20 | Tasks TRUST-017 through TRUST-020 completed: Unit tests for K4 lattice, VEX normalizers, LatticeStore aggregation, and integration test for vendor vs scanner conflict. All 20 tasks DONE. Sprint complete. | Agent |
+| 2025-12-21 | Fixed LatticeStoreTests.cs to use correct Claim property names (Issuer/Time instead of Principal/TimeInfo). All 56 tests now compile and pass. | Agent |
+| 2025-12-21 | Fixed DispositionSelector conflict detection priority (moved to priority 25, after FIXED/MISATTRIBUTED but before dismissal rules). Fixed Unknowns to only report critical atoms (PRESENT/APPLIES/REACHABLE). Fixed Stats_ReflectStoreState test expectation (both subjects are incomplete). All 110 TrustLattice tests now pass. | Agent |
