+# Plan 20-02 Summary: Data Layer client_transcripts
+
+## What Was Built
+
+Drizzle schema, query layer e server actions per i transcript delle call.
+
+## Key Files Modified
+
+- `src/db/schema.ts` — tabella `clientTranscripts` + relazioni bidirezionali + TypeScript types
+- `src/lib/lead-service.ts` — `getTranscripts(leadId)` con orderBy call_date DESC
+- `src/app/admin/leads/actions.ts` — `addTranscript` + `deleteTranscript` con requireAdmin
+
+## Self-Check: PASSED
+
+- ✓ `export const clientTranscripts = pgTable("client_transcripts", ...)` in schema.ts
+- ✓ `leadsRelations` aggiornato con `transcripts: many(clientTranscripts)`
+- ✓ `clientsRelations` aggiornato con `transcripts: many(clientTranscripts)`
+- ✓ `clientTranscriptsRelations` con one(leads) + one(clients)
+- ✓ `export type ClientTranscript` e `NewClientTranscript` esportati
+- ✓ `getTranscripts(leadId)` ordinato per `call_date DESC`
+- ✓ `addTranscript` con requireAdmin + Zod + revalidatePath
+- ✓ `deleteTranscript` con requireAdmin + revalidatePath
+- ✓ `npx tsc --noEmit` → no errors
