SkellySpeak
A multilingual conversation tutor
Practice with an in-character partner, private coach, and on-demand language help.
The implementation is built around these guarantees:
✓The conversation partner never sees the private coach thread.
✓Provider modes do not silently fall back to a different route.
✓Unreadable persisted data is reported instead of replaced with empty state.
✓The execution graph reconciles its declaration against observed model runs.
