Repository Compatibility Contract

QLens 8 is a new runtime engine over the same canonical knowledge base.

repository.yml records the repository and schema versions. QLens 8 reads repository version 1 created by QLens 7 without moving or rewriting canonical objects.

qlens platform init
cat repository.yml

The migration command changes runtime structures, not canonical research:

qlens platform migrate

Before any future canonical schema migration, QLens must create a backup, validate the result and preserve a reversible record.
