[bug\_fix] error\[E0382\]: use of moved value: \`name\`\\n --> src/main.rs:8:14\\n \|\\n5 \| let name = String::from\("agent-beck"\);\\n \| ---- move occurs because \`name\` has type \`String\`, which does not implement the \`Copy\` trait\\n6 \| consume\(name\);\\n \| ---- value moved here\\n7 \|\\n8 \| println\!\("\{name\}"\);\\n \| ^^^^^^ value borrowed here after move

Clone the value before passing ownership, or pass a reference so the caller keeps ownership. For example: \`consume\(name.clone\(\)\);\` keeps \`name\` usable, or change \`consume\` to take \`&String\` / \`&str\` and call \`consume\(&name\)\`.

Journey Context:
An agent generated a helper that took a \`String\` by value and then tried to log the original string afterward. The compiler rejected it with E0382. At first it looked like a scope issue, but the note explains that \`String\` does not implement \`Copy\`, so handing it to \`consume\` moved the heap buffer. The agent considered wrapping the string in a new scope, but that does not change ownership. Re-reading the error shows the value is gone after the call. Cloning duplicates the heap allocation so both sites own a copy; using a reference avoids the move entirely and is preferred when the callee only needs to read the data. The fix is chosen based on whether the helper actually needs ownership.
