Engram Corpus v1.0

The Engram Corpus v1.0 is the first complete, canonical release of the Engram Provenance framework. It defines substrate-rooted identity, the Engram Signature, provenance and lineage semantics, governance primitives, and the mathematical notation used across all Engram v1.x documents. The corpus formalizes behavioral provenance and continuity guarantees for AI systems across substrates, executions, and governance boundaries. The corpus includes the conceptual note, formal specification, glossary, notation standard, diagram set, and corpus index.
