# Static inventory of exceptions and state-dependent paths

This table detects syntax within each public `DobotTcp` method using AST. `raise` identifies explicit raises, `except` identifies local handlers, and helper calls identify potential indirect failure or state dependencies. **A blank cell does not imply exception-free behavior.** Callee internals, properties, transport-library failures, and thread failures are not exhaustively tracked.

## Interpretation notes

- See the [return/failure quick reference](return_failure_quick_reference.md) for ambiguous normal and transport-failure values.
- `get_motion_complete()` does not establish successful target arrival.
- Calls to `_unsupported()` lead to backend `NotImplementedError`.
- This is **static analysis**, not hardware or HTTP integration testing.
