Deterministic mode comment contradicts behavior (no special 5xx exception implemented)
- src/providers/orchestrator.ts:504-511
The inline comment states an exception for 'hard 5xx', but the code always throws in deterministic mode, preventing any fallback regardless of error type. This misleads maintainers and users of deterministic mode.
Recommendation
Either update the comment to reflect the actual behavior (no fallback in deterministic mode), or implement the documented behavior by allowing fallback on hard 5xx conditions while still preventing it otherwise.
