Incomplete checkpoint, preserved after the implementing session hit a capacity limit partway through mutation verification. NOT reviewed and NOT gate-clean: make fmt has not been run, so fmt-check currently fails on ARCHITECTURE.md and TODO.md. Work still outstanding before this is fit for review: - run make fmt and fold the result in - finish mutation-proving each of the three behaviors - verify every message string byte-for-byte against the C sources - confirm TestSeedCompatItemTables passes with its golden untouched Refs #13.
