Class IntegrityConstants

Namespace

Typhon.Engine

Assembly

Typhon.Engine.dll

The handful of on-disk layout constants an integrity consumer needs to size buffers and interpret a Locus. Mirrors the engine-internal storage constants so external callers (CLI, Workbench, tests) do not have to hard-code them.
