Status: IN
The architecture pursues defense-in-depth correctness through two complementary layers: perimeter normalization establishes clean inputs at system boundaries (serving both security and feature correctness), while structural construction (immutability, synchronized structures, state ratchets) enforces correct state transitions internally — though this structural discipline is not universally applied, with critical invariants like quorum overlap and payment atomicity remaining assumed but unenforced. Where both layers are present, they reduce an important class of corruption bugs, but gaps in structural enforcement mean full lifecycle coverage is not yet achieved.
Perimeter normalization and structural construction are complementary correctness layers
