Phase 2: Precedents

Phase 2: Precedents

Phase 2 presents relevant STJ precedents as interactive cards. Users evaluate each precedent (useful or not useful) and select the ones most relevant to their case. These selections directly influence the risk analysis in Phase 3.

What Happens

1. Diagnosis context from Phase 1 is sent to Valter
2. Valter returns relevant precedents via /v1/retrieve and /v1/similar_cases
3. Precedent cards appear in the WorkCanvas
4. User evaluates each precedent (relevant / not relevant)
5. A precedent_picker block provides a selection interface
6. Selected precedents feed into Phase 3 (Risks)

Block Types Produced

Block Type	Purpose
precedent	Individual STJ precedent card with case details, ementa, and key reasoning
precedent_picker	Selection interface showing total precedents and selected count

Server Actions

// Evaluate a single precedent
evaluatePrecedent(sessionId: string, processoId: string, evaluation: PrecedentEvaluation)
  → Returns: BriefingFlowState

Valter API Integration

Endpoint	Purpose
/v1/retrieve	Primary search for precedents matching the Phase 1 diagnosis
/v1/similar_cases	Find cases similar to the user’s selected precedents

Block Factory

// Create a precedent block from Valter search results
createPrecedentData(precedent: Precedent): PrecedentBlockData

// Create the picker interface
createPrecedentPickerData(total: number, precedentBlockIds: string[]): PrecedentPickerBlockData

🚧 Planned Feature — Phase 2 is planned for v0.4 milestone.
