`RUN COMMAND` is documented and validated as a trusted-code capability: it executes shell commands with the user's permissions and is not a sandbox. Claro does not claim untrusted-script safety or use a fragile blacklist sanitizer. Focused documentation coverage is `tools/validate_trusted_command_docs.py`.
`GET ... KEY ... AS ...` now releases its temporary map and key values after lookup. `python3 tools/validate_get_key_expression_cleanup.py` reproduced 1,004,000 leaked bytes before the change and passes after it with ASan/UBSan/LSan enabled. `EXISTS FILE ... AS ...` now releases its evaluated path value after checking it; `python3 tools/validate_exists_expression_cleanup.py` first reproduced 62,000 leaked bytes across 2,000 calls, then passed with ASan/UBSan/LSan enabled. These are narrow expression-temporary cleanup slices, not a claim that all runtime allocations are leak-free. The `COPY FILE` and `MOVE FILE` commands now also release their evaluated source/destination path values after conversion to strings; `python3 tools/validate_copy_move_expression_cleanup.py` reproduced 74,000 bytes leaked across 1,000 copy/move pairs before the fix and is the focused ASan/UBSan/LSan regression gate. `CREATE FOLDER ...` now releases its evaluated path value after converting it to an owned path string; `python3 tools/validate_create_folder_expression_cleanup.py` reproduced 200,000 leaked bytes across 2,000 calls before the fix and passes with ASan/UBSan/LSan enabled. This narrow cleanup slice does not establish that all runtime allocations are leak-free.

The `DELETE FILE ...` and `DELETE FOLDER ...` commands now release their evaluated path values after converting the paths to owned strings. `python3 tools/validate_delete_expression_cleanup.py` first reproduced 178,000 leaked bytes across 2,000 `DELETE FILE` expression evaluations under ASan/UBSan/LSan, then passed after cleanup. This check covers expression ownership; malformed-input diagnostic paths still have the previously documented `rt_error` message leak.
