Terraphim demonstrates automated command correction from failure to execution

The Harbour project uses an OpenCode adapter to capture command failures, such as a misspelled Python flag. The system records the error and exit status, then allows a human reviewer to propose a correction. This correction is explicitly promoted to a tool-preference record and compiled into a role thesaurus. The process ensures that when the same mistake occurs in another session, the corrected command is automatically used instead. The demonstration shows the full workflow from failed command to successful execution.
