## 2 · Modello concettuale

- **FamilyGroup** (`schema.prisma:245`): aggregazione di Client legati. Multi-generation, multi-entity. AUM aggregato calcolato cross-cliente.
- **LegalEntity** (Fase 3, `schema.prisma:257`): persona fisica/giuridica nella struttura (PERSON | TRUST | HOLDING | FOUNDATION | SPV). Owner alternativo a `FamilyGroup`.
- **Entity** (Fase 4 Premium, `schema.prisma:2116`): entity tree multi-jurisdiction. Pattern Masttro entity map / Eton entity tree. Tipi: TRUST, HOLDING, FOUNDATION, SPV, individuo. Beneficiaries+fiduciaries JSON. `taxIdMasked` PII-safe.
- **EntityRelationship** (`schema.prisma:2161`): relazione DAG fra Entity. Tipi: OWNS / CONTROLS / BENEFICIARY_OF / TRUSTEE_OF / PARENT_OF / GUARANTEES. Con `ownershipPct`, `votingPct`, `effectiveFrom/To`.
- **FamilyProposal** (workflow figlio→genitore Fase 6 Portal Generazionale, `schema.prisma:154`): proposta inbox/outbox. Tipi `kind`: `SUGGEST_ADVISOR_CALL` | `REBALANCE` | `CHARITY` | `NEW_PRODUCT` | `OTHER`. Status `pending` | `approved` | `rejected` | `expired`. Decisione via `decidedVia: passkey|password|call|magic-link`.
- **VotingProposal** (Fase 4 UHNW governance, `schema.prisma:2677`): proposta formale family office. Mechanism: `SIMPLE_MAJORITY` (default 50%) | `SUPERMAJORITY` (66.67%) | `UNANIMOUS` (no NO) | `WEIGHTED` | `QUADRATIC`. `quorumPct` (default 50%) + `thresholdPct` (default 50%). Window `votingOpensAt` → `votingClosesAt`. Outcome JSON: `{totalVotes, yesPct, noPct, abstainPct, quorumReached, passed}`.
- **VotingBallot** (`schema.prisma:2711`): voto individuale `YES|NO|ABSTAIN` con `weight` (default 1) + `rationale?` + `proxyOf?`. Composite key `proposalId+voterId` upsert (cambio voto consentito finché OPEN).
- **PersonaPack visibility**: `FO_PRINCIPAL` (head of family office) e `FO_STAFF` (staff) vedono governance completa. `NEXTGEN_HEIR` vede entity tree + simulator (no voting su proposal adulti). `RETAIL_CLIENT` non vede family-voting.

### Pattern architetturali
- **Voting quorum + threshold dinamici** (`family-voting.service.ts:tally` 148-198): per ogni mechanism calcola `passed` differente — `UNANIMOUS` = `noWeight===0 && yesWeight>0`, `SUPERMAJORITY` = `yesPct >= 66.67`, `WEIGHTED`/`QUADRATIC`/`SIMPLE_MAJORITY` = `yesPct >= proposal.thresholdPct`. Quorum check: `totalVotes > 0` (placeholder, da raffinare con `quorumPct` reale vs members count).
- **Ballot upsert idempotente** (`family-voting.service.ts:127-145`): `votingBallot.upsert({where:{proposalId_voterId},update,create})` permette cambio voto finché proposal `ACTIVE`. Update aggiorna anche `castAt`.
- **Time-window validation** (`family-voting.service.ts:120-126`): pre-cast verifica `votingClosesAt > now > votingOpensAt`. BadRequestException se "voting period closed" o "not yet open".
- **Proposal magic-link dual-channel** (`family-proposals.service.ts:106-122`): su `create()`, se target ha `user.email`, invia magic-link via `MagicLinkService.request({email, redirectTo, scope:'proposal-approve', proposerName, proposalTitle, metadata:{proposalId}, origin})`. Catch silent + log warn (delivery failure non blocca proposal creation).
- **Same-family validation** (`family-proposals.service.ts:80-89`): se proposer e target hanno `familyGroupId` diversi → ForbiddenException "Puoi proporre solo a membri della tua famiglia". Permette cross-family se uno dei due ha `null` (singleton).
- **Decide state machine** (`family-proposals.service.ts:148-184`): `decide(proposalId, approverUserId, status, extras)` enforza (1) proposal exists, (2) tenant_id match (cross-tenant defense), (3) status `pending` (no double-decide), (4) target.userId === approverUserId (solo destinatario decide). Update atomic con `decidedAt = NOW()`, `decidedVia`, `rejectionReason`.
- **AUM aggregato cross-cliente** (`family-group.service.ts:findAll` 51-101): per ogni FamilyGroup somma `client.portfolios[].assets[].currentValue` + `client.externalAssets[].valuations.latest.amount`. EUR base.
- **GenerationalRisk band** (`family-group.service.ts:findAll`): `youngestAge`/`oldestAge` calcolato da `birthDate`. Span generazionale. Risk band: low/medium/high in funzione di multi-generation.
- **Entity tree DAG** (`entity-tree.service.ts:listEntities` + relations): output `{entities[], relations[], jurisdictionCount, entityTypeCount, totalEstimatedAssets}`. Entity tree non è strict tree (può avere DAG con OWNS multipli).
- **myFamilyMembers anti-self** (`family-group.service.ts:107-130`): vista NextGen "a chi mando proposta" — escude self (`id: { not: me.id }`), ritorna `{id, name, birthDate, role}` membri famiglia.

### Decisioni storiche
- **Commit `9409e3a` "feat(api): portal generazionale fase 6 - FamilyProposal workflow figlio-genitore con magic link"**: introduzione FamilyProposal schema + service + magic-link `scope:proposal-approve` con metadata `{proposalId}`. Frontend `/portal/proposals/new`, `/portal/proposals/[id]`, `/portal/senior/storia`.
- **Commit `f6a1606` "feat(web): family-groups cleanup phantoms, clickable cards, detail page, insights & suggestions"**: insights cards FE + AI grouping suggestion (`GroupingSuggestion` interface in `family-group.service.ts:40-46`).
- **Commit `8ed6f37` "feat(slice-1-4)"**: introduzione VotingProposal + VotingBallot + Entity + EntityRelationship Fase 4 Premium.
- **Commit `56f5bdb` "fix(api): unblock build for family-group + events"**: build issue post slice 1-4.
- **Cascata "filosofica" Cliente → Advisor → Admin** (rif `docs/agent-handoff/handoff-valoswiss.md`): cliente vede semplicità ("ho una proposta da approvare"), advisor vede orchestrazione ("5 votanti, 3 approvati, 1 rifiutato"), admin vede compliance (audit log completo).
- **passkey/WebAuthn integration**: `Credential` model (`schema.prisma:180`) registra public key COSE. `decidedVia='passkey'` differenzia da password/magic-link/call.

### Edge cases noti
- **Magic-link expiresAt 15min default**: per `proposal-approve` scope, il default può essere troppo corto se email arrivata in ritardo. Verifica `magic-link.service.ts` config per scope-specific override (es. 7 giorni per proposal).
- **`consumedAt` anti-replay**: ogni magic link è single-use. Se cliente clicca link twice, secondo accesso → 403. Re-emit nuovo link via `/family-proposals/:id/resend-link` (TODO).
- **Email Resend delivery failure** (`family-proposals.service.ts:117-121`): catch silent, log warn. Proposal creata ma email non inviata. Cliente non sa di poter approvare → segnale `outbox` con `inviteFailed:true` (TODO).
- **NextGen Heir vota su proposal adulti**: pack `NEXTGEN_HEIR` per definizione pedagogical, non vota. Se erroneamente assegnato voter → tally include weight ma legalmente non valido.
- **SUPERMAJORITY senza NO**: se `noWeight===0 && yesWeight===100%`, mechanism SUPERMAJORITY passa con threshold 66.67%. Edge: `UNANIMOUS` invece richiede `yesWeight>0` esplicito (no proposal "pass" con 0 voti totali).
- **Cross-tenant defense via tenant_id explicit**: `family-proposals.service.ts:160` `proposal.tenant_id !== tenantId` → NotFoundException (non "Forbidden" — info hiding).
- **Quorum check non implementato completamente** (`family-voting.service.ts:187`): `quorumReached: totalVotes > 0` placeholder. Manca confronto vs members count del FamilyGroup → quorum effettivo solo `>0`.

### Bug ricorrenti
- **Multi-tenancy `tenant_id` filter dimenticato** in queries Voting (`family-voting.service.ts:50-90` FamilyVotingService prende solo `proposalId`/`familyGroupId`, non filtra tenant). Defense in depth: aggiungere `tenant_id` esplicito in tutte le query (DAEO).
- **Decision via `magic-link` con expired token** (`apps/api/src/auth/magic-link/magic-link.service.ts:120-145`): callback `/auth/magic-link/consume?token=…` verifica `expiresAt`. Token expired → 401 + UI mostra "Link scaduto, contattare advisor".
- **Email Resend rate limit** (`apps/api/src/modules/email/resend.service.ts:80-110`): limite gratuito 100 email/giorno. Su tenant con 50+ proposal/giorno → some delivery fails. Workaround: aumentare piano Resend.
- **Familygroup `findAll` heavy** (`family-group.service.ts:51-69`): include `clients.portfolios.assets` + `externalAssets.valuations` → JOIN multi-livello. Per tenant con 100+ famiglie può essere lento. Ottimizzare con projection select per fields specifici.
- **proposal.payload JSON arbitrario** (`family-proposals.service.ts:60-78`): nessuna validazione schema → cliente potrebbe inserire dati troppo grandi. Validation in DTO `payload?: any` non strutturato. TODO: definire union type per kind.
- **Quorum check non implementato** (`family-voting.service.ts:185-198`): `quorumReached: totalVotes > 0` placeholder. Manca confronto vs members count del FamilyGroup → quorum effettivo solo `>0`.
