# Cortex OS CTO Context This context defines local product language for the Cortex OS CTO planning workspace. It is child-local glossary language and does not create Core authority. ## Language **CTO Product Surface**: A governed operator-facing product area for delegating bounded code-change work while preserving Cortex OS authority, evidence, and approval rules. _Avoid_: CTO app, autonomous developer, coding bot **Case Candidate Backend**: The proposed Case-based execution backend for real-repo code-change work, admitted only after adapter proof, validator coverage, and governed routing. _Avoid_: Case default, Case authority, replacement kernel **CTO Harness**: The adapter conformance and evidence validation module that normalizes backend behavior into a stable CTO evidence interface. _Avoid_: execution authority, final reviewer, product readiness proof **Harness Evidence Interface**: The stable artifact and event contract used to compare backends and prove bounded execution results. _Avoid_: loose evidence bundle, backend logs, success claim **Target Repository**: The owned source repository receiving bounded, approved, evidence-producing code changes. _Avoid_: vendor source, hidden workspace, disposable scratch by default **Copied Repository Fixture**: A runtime copy of an owned local source repository used to prove backend behavior without mutating the source repository or a Target Repository. _Avoid_: Target Repository, live repo, external developer source
