rc=0 secs=14One line per abuse case (requirements.md § Security considerations)
| # | Abuse case | Negative test(s) | Result |
|---|---|---|---|
| 1 | /model naming an unlisted model is refused, model kept | tests/security/test_command_arguments.py | pass |
| 2 | /effort outside low/medium/high is refused, effort kept | tests/security/test_command_arguments.py | pass |
| 3 | A stranger's command, completion or cancel is answered as if the task did not exist | test_complete_roles.py, test_command_roles.py, test_sub_task_flood.py | pass |
| 4 | A watcher cannot complete, cancel, /model, /effort or /sub-task | test_command_roles.py, test_complete_roles.py, test_command_arguments.py | pass |
| 5 | Shell, path, control-character or prompt-injection argument text is only a value | test_command_arguments.py | pass |
| 6 | /sub-task floods hit the 429 rate limit before Temporal | test_sub_task_flood.py | pass |
| 7 | A symlinked or foreign-owned ~/.tiny-harness or config is refused, exit 2 | test_home_paths.py (also T11 step 5, by hand) | pass |
| 8 | The directory is created 0700 and the file 0600 | test_home_paths.py (also T11 step 2, stat) | pass |
| 9 | An unregistered /x is an ordinary untrusted message | test_command_roles.py | pass |
| 10 | A remote command executor gets scrubbed context; its reply is untrusted text | test_remote_command_executor.py | pass |
The server sets these fields itself (lifecycle, model, reasoning_effort) and refuses them in a client's envelope (test_server_controlled_fields.py, pass).
