# HARN-ORC-010 — execution target path cannot be found
**Category:** Orchestration (ORC)
**Variant:** `Code::ExecutionTargetMissing` (execution target missing)
## What it means
An orchestration construct — agent / workflow / pipeline / tool definition, or a
`select` block — does not satisfy the structural rules Harn enforces. These
constructs carry runtime semantics that depend on a small set of well-formed
shapes.
Specifically: execution target path cannot be found.
## How to fix
- Re-read the orchestration construct's spec section and align the arity / type / structure.
## Stability
This code is stable. Its identifier, category, and meaning will not change
without a deprecation cycle. Cross-language tooling and IDE integrations can
dispatch on it directly.
