[bug\_fix] use of moved value \[E0382\]: value used here after move

Clone the value if you need to keep using the original, or restructure to borrow instead of taking ownership. For a \`String\`, change \`let t = s;\` to \`let t = s.clone\(\);\` so both variables own independent copies.

Journey Context:
An agent wrote a helper that consumed a \`String\` and then tried to log the same string afterward. The compiler flagged E0382 on the second use. The agent initially assumed assignment was like other languages and that both variables could read the data. Reading the error explanation showed that \`String\` owns its heap buffer and has move semantics, so assigning it transfers ownership. The fix was either to pass \`&s\` to the helper or to clone when the helper truly needed ownership. Cloning was chosen because the helper required an owned value, and the original was still needed for the log line.
