The successful focused deconstruct calls onFocusedContribution which
updates parent state, but never persisted the new collection to
sessionStorage. This meant an immediate reload would lose the
contribution.
Fix: add a useEffect in ReasoningWorkspace that watches the
focusedContributions prop for changes and saves via the existing
saveSession mechanism. A ref guard prevents double-save alongside the
existing updateStatus-success effect.
- Add focusedContributions state + appendFocusedContribution callback in ScenarioForm
- Contributions persist through session lifecycle (save/restore/restart)
- Pass onFocusedContribution and focusedContributions to ReasoningWorkspace
- Call onFocusedContribution on successful deconstruct with full result shape
- Test: contribution sequence, field preservation, same/different target coexistence
