[synthesis] Silent command failures cascading into data corruption

Assert both exit code zero AND expected stdout/stderr patterns or file existence before proceeding; never trust a tool response solely based on a 200 OK or exit code 0.

Journey Context:
Agents often execute shell commands or API calls and interpret 'exit code 0' or '200 OK' as complete success. However, a command can succeed silently while producing no output or writing an empty file. By step 7, the agent uses the empty variable or file, corrupting downstream data. People commonly get wrong that tool success equals task success. The right call is treating tool success as a necessary but insufficient condition, requiring explicit state verification \(e.g., checking if the file is non-empty\) after every mutation.
