## New Entities
### K1BoxDefinition (Reference / Dimension)
Replaces the global rows of `CellMapping`. One row per unique IRS K-1 box identifier. Serves as the FK target for `K1LineItem.boxKey`.
| Column | Type | Constraints | Notes |
|---|---|---|---|
| `boxKey` | `String` | **PK** | IRS box identifier: `"1"`, `"9a"`, `"20-A"`, `"11-ZZ*"` |
| `label` | `String` | NOT NULL | Human-readable: `"Ordinary business income (loss)"` |
| `section` | `String?` | — | `HEADER`, `PART_I`, `PART_II`, `SECTION_J`, `SECTION_K`, `SECTION_L`, `SECTION_M`, `SECTION_N`, `PART_III` |
| `dataType` | `String` | DEFAULT `"number"` | `number`, `string`, `percentage`, `boolean` |
| `sortOrder` | `Int` | NOT NULL | Display ordering (matches IRS form order) |
| `irsFormLine` | `String?` | — | `"Box 1"`, `"Section J, Line 1"`, `"Part I, Line A"` |
| `description` | `String?` | — | Extended description for LLM context |
| `isCustom` | `Boolean` | DEFAULT `false` | `true` for auto-created box keys not in IRS standard set (FR-017) |
| `createdAt` | `DateTime` | DEFAULT `now()` | |
| `updatedAt` | `DateTime` | `@updatedAt` | |
**Indexes**: `@@index([section])`, `@@index([sortOrder])`
**Mapped name**: `k1_box_definition`
**Seed data**: Migrated from `IRS_DEFAULT_MAPPINGS` array in `cell-mapping.service.ts` (80+ entries). Mapping: `boxNumber` → `boxKey`, `label` → `label`, `cellType` → `dataType`, `sortOrder` → `sortOrder`, `description` → `description`. Section derived from sortOrder ranges (0–9 = HEADER, 10–19 = PART_I, 20–29 = PART_II, 30–39 = SECTION_J, 40–49 = SECTION_K, 50–59 = SECTION_L, 60–63 = SECTION_M/N, 100+ = PART_III).
---
### K1BoxOverride (Per-Partnership Display Override)
Replaces the per-partnership rows of `CellMapping`. Controls display customization without affecting data integrity.
| Column | Type | Constraints | Notes |
|---|---|---|---|
| `id` | `String` | PK (UUID) | |
| `boxKey` | `String` | FK → `K1BoxDefinition.boxKey` | Which box to override |
| `partnershipId` | `String` | FK → `Partnership.id` | Which partnership |
| `customLabel` | `String?` | — | Override display label |
| `isIgnored` | `Boolean` | DEFAULT `false` | Hide this box for this partnership |
| `createdAt` | `DateTime` | DEFAULT `now()` | |
| `updatedAt` | `DateTime` | `@updatedAt` | |
**Unique**: `@@unique([boxKey, partnershipId])`
**Indexes**: `@@index([partnershipId])`
**Mapped name**: `k1_box_override`
**On delete**: CASCADE from both `K1BoxDefinition` and `Partnership`
---
### K1LineItem (Fact Table)
One financial line item per box per K-1 document. Core normalized data store replacing `KDocument.data` JSON.
| Column | Type | Constraints | Notes |
|---|---|---|---|
| `id` | `String` | PK (UUID) | |
| `kDocumentId` | `String` | FK → `KDocument.id` | Which K-1 document |
| `boxKey` | `String` | FK → `K1BoxDefinition.boxKey` | Which IRS box |
| `amount` | `Decimal?` | `@db.Decimal(15,2)` | Dollar amount. NULL for non-numeric values. |
| `textValue` | `String?` | — | Non-numeric values: `"SEE STMT"`, `"true"`, etc. |
| `rawText` | `String?` | — | Original extracted text before parsing |
| `confidence` | `Decimal?` | `@db.Decimal(3,2)` | OCR confidence 0.00–1.00. NULL if manual entry. |
| `sourcePage` | `Int?` | — | PDF page number where extracted |
| `sourceCoords` | `Json?` | — | `{x, y, width, height}` bounding box on page |
| `isUserEdited` | `Boolean` | DEFAULT `false` | True if user modified during verification |
| `isSuperseded` | `Boolean` | DEFAULT `false` | True if replaced by a newer version (ESTIMATED→FINAL) |
| `createdAt` | `DateTime` | DEFAULT `now()` | |
| `updatedAt` | `DateTime` | `@updatedAt` | |
**Partial unique index** (raw SQL, not expressible in Prisma):
```sql
CREATE UNIQUE INDEX "k1_line_item_active_unique"
ON "k1_line_item" ("k_document_id", "box_key")
WHERE "is_superseded" = false;
```
**Indexes**: `@@index([kDocumentId, boxKey])`, `@@index([kDocumentId])`, `@@index([boxKey])`, `@@index([isSuperseded])`
**Mapped name**: `k1_line_item`
**On delete**: CASCADE from `KDocument`
---
## Modified Entities
### KDocument (existing — minimal changes)
| Change | Detail |
|---|---|
| Add `lineItems` relation | `K1LineItem[]` — reverse relation for Prisma |
| `data` column | **Retained as-is** — immutable JSON archive (FR-008) |
| No column drops | `data`, `previousData` preserved permanently |
### CellAggregationRule (existing — update references)
| Change | Detail |
|---|---|
| `sourceCells` JSON | Values are already strings like `["1", "8", "9a"]` — these match `K1BoxDefinition.boxKey` directly |
| No schema change | The `sourceCells` array doesn't need migration; it naturally references boxKey strings |
### CellMapping (existing — to be dropped)
| Phase | Action |
|---|---|
| Phase 1 (additive) | Leave in place alongside K1BoxDefinition |
| After backfill verified | Drop table via migration. Remove `CellMappingService`, `CellMappingController`, `CellMappingModule` |
---
## Prisma Schema
```prisma
/// Global IRS K-1 box reference. One row per unique box identifier.

```
**Relations to add to existing models**:
```prisma
// In model KDocument — add:
lineItems K1LineItem[]
// In model Partnership — add:
boxOverrides K1BoxOverride[]
```
---
## State Transitions
### K1LineItem Versioning (ESTIMATED → FINAL)
```
State 1: ESTIMATED K-1 confirmed
K1LineItem rows created with isSuperseded = false
State 2: FINAL K-1 imported for same KDocument
1. UPDATE K1LineItem SET isSuperseded = true WHERE kDocumentId = X AND isSuperseded = false
2. INSERT new K1LineItem rows with isSuperseded = false
3. Old rows preserved for audit trail
Query pattern (always):
WHERE isSuperseded = false
```
### CellMapping → K1BoxDefinition Migration
```
Phase 1: Both tables exist
- K1BoxDefinition seeded from IRS_DEFAULT_MAPPINGS
- CellMapping continues to serve existing code
Phase 2: Dual-read
- New code reads K1BoxDefinition
- Old code gradually migrated
Phase 3: CellMapping dropped
- Migration removes table
- Service/controller/module deleted
```
---
## Validation Rules
| Entity | Rule | Enforcement |
|---|---|---|
| K1BoxDefinition | `boxKey` is non-empty string | Application + PK constraint |
| K1BoxDefinition | `dataType` ∈ `{number, string, percentage, boolean}` | Application validation |
| K1LineItem | `amount` XOR `textValue` populated (not both null, not both non-null for numeric types) | Application validation layer |
| K1LineItem | `confidence` ∈ [0.00, 1.00] | Application validation |
| K1LineItem | `boxKey` exists in K1BoxDefinition | FK constraint (database) |
| K1LineItem | At most 1 active row per (kDocumentId, boxKey) | Partial unique index (database) |
| K1BoxOverride | One override per (boxKey, partnershipId) | @@unique constraint (database) |

# Implementation Plan: K-1 Normalized Data Model
**Branch**: `006-k1-model-review` | **Date**: 2026-03-20 | **Spec**: [spec.md](spec.md)
**Input**: Feature specification from `/specs/006-k1-model-review/spec.md`
## Summary
Transform K-1 financial data storage from JSON blob (`KDocument.data`) to a normalized relational model (`K1LineItem` fact table + `K1BoxDefinition` reference table). This enables SQL-level aggregation, referential integrity on box keys, field-level provenance tracking, and future NL-to-SQL/LLM queries. The migration follows a 3-phase approach: (1) additive schema + backfill, (2) dual-write in `K1ImportService.confirm()`, (3) switch `K1AggregationService` to SQL reads. `CellMapping` is fully replaced by `K1BoxDefinition`. `KDocument.data` is retained as an immutable archive. Backend-only — no Angular UI changes.
## Technical Context
**Language/Version**: TypeScript 5.x (strict mode, `noUnusedLocals`, `noUnusedParameters`)
**Primary Dependencies**: NestJS 11+ (module-based DI), Prisma ORM 6.x, PostgreSQL 16, Redis (caching), pdfjs-dist (extraction — unaffected by this feature)
**Storage**: PostgreSQL via Prisma (Docker dev: port 5434). All schema changes via `prisma migrate dev`.
**Testing**: Jest (unit + integration). `jest.config.ts` at root, per-project configs. E2E with Prisma test DB.
**Target Platform**: Linux server (Railway deployment), Docker containers for dev
**Project Type**: Web service (NestJS monorepo backend — `apps/api`)
**Performance Goals**: SQL aggregation queries on K1LineItem within 50ms for up to 1,000 K-1 documents (SC-002)
**Constraints**: Zero-downtime migration; existing UI reading `KDocument.data` must continue working (SC-005); no direct SQL — Prisma only (Constitution III)
**Scale/Scope**: <100 K-1 documents/year, <50 partnerships, ~50 IRS box definitions. Low write volume, high read volume (dashboards).
### Existing Code Inventory
| Component | Location | Lines | Role in Migration |
|---|---|---|---|
| **Prisma Schema** | `prisma/schema.prisma` (L543–710) | ~170 | Add `K1BoxDefinition`, `K1LineItem` models; eventually drop `CellMapping` |
| **CellMapping service** | `apps/api/src/app/cell-mapping/cell-mapping.service.ts` | 468 | Houses `IRS_DEFAULT_MAPPINGS` array (~80 entries) and `seedDefaultMappings()` — will be replaced by `K1BoxDefinitionService` |
| **K1AggregationService** | `apps/api/src/app/k1-import/k1-aggregation.service.ts` | 120 | `computeForKDocument()` iterates `Object.entries(data)` JSON — must switch to `K1LineItem` SQL aggregation |
| **K1ImportService.confirm()** | `apps/api/src/app/k1-import/k1-import.service.ts` (L530–760) | ~230 | Builds `kDocumentData` from `verifiedData.fields`, writes JSON blob — add dual-write to `K1LineItem` |
| **IRS_DEFAULT_MAPPINGS** | `cell-mapping.service.ts` (L10–140) | 130 | 80+ entries with boxNumber, label, description, cellType, sortOrder — seed source for `K1BoxDefinition` |
| **DEFAULT_AGGREGATION_RULES** | `cell-mapping.service.ts` (L142–165) | 24 | 3 rules (Total Ordinary Income, Capital Gains, Deductions) — migrate to reference `K1BoxDefinition` |
### Key Data Shapes (Current)
**KDocument.data** (JSON blob — the data being normalized):
```json
{"1": 50000, "9a": -1200, "11-ZZ*": 500, "20-A": 1200, "FINAL_K1": true}
```
**CellMapping** (the reference being replaced):
```
{ boxNumber: "1", label: "Ordinary business income (loss)", cellType: "number", sortOrder: 100, isCustom: false, isIgnored: false, partnershipId: null }
```
**verifiedData.fields** (input to confirm()):
```
[{ boxNumber: "1", numericValue: 50000, rawValue: "50,000", subtype: null, confidence: 0.95 }]
```
## Constitution Check
_GATE: Must pass before Phase 0 research. Re-check after Phase 1 design._
| # | Gate (from Constitution) | Status | Post-Design Re-check |
|---|---|---|---|
| I | **Nx Monorepo Structure**: Respect project boundaries | PASS | PASS — 2 Nx projects confirmed: `apps/api` + `libs/common`. K1BoxOverride (3rd table) is still within `apps/api`. |
| II | **NestJS Module Pattern**: Module → Controller → Service | PASS | PASS — `K1BoxDefinitionModule` follows pattern. `K1MaterializedViewService` added to existing K1ImportModule. |
| III | **Prisma Data Layer**: No direct SQL; migrations required | **WARN** | **WARN** — 3 raw SQL uses: (1) `COMMENT ON` in migration, (2) materialized view DDL+refresh, (3) backfill `jsonb_each()` + partial unique index. All justified below. |
| IV | **TypeScript Strict**: No dead code | PASS | PASS — `CellMapping` module deleted in final migration phase, not left dead. |
| V | **Simplicity First / YAGNI / Max 3 Nx projects** | PASS | PASS — 2 Nx projects. K1BoxOverride is simpler than embedding overrides in K1BoxDefinition with nullable partnershipId. |
| VI | **Interface-First Design**: Contracts in `@ghostfolio/common` | PASS | PASS — Contracts defined in `specs/006/contracts/`, moved to `libs/common` during implementation. |
| VII | **Testing**: Jest | PASS | PASS — Backfill validation query defined in research.md. Unit + integration tests planned. |
**Gate III Justification**: Prisma ORM does not support materialized views or JSONB iteration natively. Two specific operations require `$executeRawUnsafe()`:
1. `CREATE MATERIALIZED VIEW` / `REFRESH MATERIALIZED VIEW CONCURRENTLY` (FR-010/011)
2. Backfill migration iterating `jsonb_each()` over `KDocument.data` (FR-006)
Both are encapsulated in migration files or a single service method — not scattered across the codebase. This is the minimum deviation from "Prisma only" required by the feature.

**Structure Decision**: Backend-only feature using 2 Nx projects (`apps/api` + `libs/common`). One new NestJS module (`k1-box-definition`) replaces the existing `cell-mapping` module. All other changes modify existing files in-place.
## Complexity Tracking
| Violation | Why Needed | Simpler Alternative Rejected Because |
|---|---|---|
| Raw SQL for materialized views (Constitution III) | Prisma ORM has no `CREATE MATERIALIZED VIEW` support | Cannot achieve FR-010/011 (cross-entity dashboard queries within 50ms) without pre-computed views. Regular Prisma queries would require O(n) JOINs at read time. |
| Raw SQL for backfill migration (Constitution III) | Prisma cannot iterate JSONB keys server-side | Alternative: fetch all KDocuments to Node.js, parse JSON, insert rows via Prisma. Rejected: unbounded memory for large datasets, no transactional atomicity, orders of magnitude slower than a single SQL `INSERT ... SELECT FROM jsonb_each()`. |

# Quickstart: 006-k1-model-review
**Branch**: `006-k1-model-review`
**Spec**: [spec.md](spec.md) | **Plan**: [plan.md](plan.md) | **Data Model**: [data-model.md](data-model.md)
---
## What This Feature Does
Transforms K-1 financial data from JSON blob storage (`KDocument.data`) to normalized relational tables:
- **K1BoxDefinition** — Reference table of valid IRS K-1 box identifiers (replaces `CellMapping`)
- **K1BoxOverride** — Per-partnership display overrides (custom labels, ignored boxes)
- **K1LineItem** — Fact table: one row per box per K-1 document (replaces JSON blob reads)
This enables SQL-level aggregation, referential integrity on box keys, and field-level provenance tracking.
## Prerequisites
```bash
# Docker containers running (PostgreSQL + Redis)
docker compose -f docker/docker-compose.dev.yml up -d
# Dependencies installed
npm install
# Environment variables (copy from .env.example if needed)
# DATABASE_URL=postgresql://user:password@localhost:5434/ghostfolio
```
## Development Workflow
### 1. Schema Changes
All new models are in `prisma/schema.prisma`. After modifying:
```bash
# Validate schema
npx prisma validate
# Generate diff SQL (shadow DB workaround — P3006 error in dev)
npx prisma migrate diff --from-schema-datasource prisma/schema.prisma --to-schema-datamodel prisma/schema.prisma --script
# Create migration file manually, then apply:
npx prisma db execute --file prisma/migrations/<name>/migration.sql --schema prisma/schema.prisma
npx prisma migrate resolve --applied <name>
# Regenerate Prisma Client (kill node processes first on Windows for DLL lock)
npx prisma generate
```
### 2. Key Files
| File | Purpose |
|---|---|
| `prisma/schema.prisma` | K1BoxDefinition, K1BoxOverride, K1LineItem models |
| `apps/api/src/app/k1-box-definition/` | Service + controller for box definitions & overrides |
| `apps/api/src/app/k1-import/k1-import.service.ts` | `confirm()` creates K1LineItem rows from verified PDF fields |
| `apps/api/src/app/k1-import/k1-aggregation.service.ts` | SQL-based aggregation over K1LineItem |
| `apps/api/src/app/k1-import/k1-materialized-view.service.ts` | Refreshes `mv_k1_partnership_year_summary` on data changes |
| `apps/api/src/app/k1-import/k1-field-mapper.service.ts` | Maps PDF fields using K1BoxDefinitionService.resolve() |
| `libs/common/src/lib/interfaces/` | K1BoxDefinition, K1LineItem TypeScript types |
### 3. Running the API
```bash
# Start API (watches for changes)
npx nx serve api
# API runs at http://localhost:3333
```
### 4. Testing
```bash
# SC-006 comparison test (quality gate — must pass before commits)
node --experimental-strip-types test/import/k1-comparison.test.mts
# Run all tests
npx nx test api
# Run specific test file
npx jest --config apps/api/jest.config.ts --testPathPattern="k1-box-definition"
```
### 5. Migrations Applied
Migrations in this branch (applied in order):
1. **20260321004726_add_k1_normalized_model** — Create K1BoxDefinition, K1BoxOverride, K1LineItem tables. Seed 79 IRS box definitions. Add partial unique index. Drop unused KDocument/K1ImportSession columns.
2. **20260321010000_drop_cell_mapping** — Drop CellMapping and CellAggregationRule tables + FK constraints.
3. **20260321020000_widen_k1_line_item_amount_precision** — Widen K1LineItem.amount from Decimal(15,2) to Decimal(15,6) for percentage fields.
4. **20260321030000_add_k1_materialized_views** — Create `mv_k1_partnership_year_summary` materialized view with unique index.
## Architecture Notes
- **Clean-break migration**: CellMapping tables are dropped. No dual-write or backfill needed — PDFs are re-imported through the new pipeline.
- **K1LineItem is authoritative**: `KDocument.data` (Json?) is optional convenience snapshot only. All queries read from K1LineItem.
- **Aggregation via SQL**: `K1AggregationService` uses `prisma.k1LineItem.findMany()` and `groupBy()` instead of iterating JSON blobs.
- **Materialized views**: `mv_k1_partnership_year_summary` is refreshed via `REFRESH MATERIALIZED VIEW CONCURRENTLY` triggered by `@OnEvent('k-document.changed')` after confirm.
- **isSuperseded pattern**: When K-1 transitions ESTIMATED→FINAL, old K1LineItem rows are marked `isSuperseded = true`, new rows inserted. All queries filter `WHERE isSuperseded = false`.
- **Auto-create on import**: `K1BoxDefinitionService.autoCreateIfMissing()` creates custom box definitions for PDF-extracted fields not in the IRS defaults (e.g., Section J, Section L, Box 20 sub-items).
## Contracts
TypeScript interfaces are in `libs/common/src/lib/interfaces/`:
- `k1-box-definition.interface.ts` — K1BoxDefinition, K1BoxOverride, K1BoxDefinitionResolved
- `k1-line-item.interface.ts` — K1LineItem, K1LineItemWithDefinition, CreateK1LineItemDto, K1AggregationResult
## Out of Scope
- Angular dashboard UI (future spec)
- LLM NL-to-SQL integration (future spec)
- PDF extraction changes (covered by 005-k1-parser-fix)

## 1. Prisma `@@map` and `COMMENT ON` Annotations (FR-012)
### Decision
**Use raw SQL statements appended to the Prisma-generated migration file.** After running `prisma migrate dev --create-only` to generate the structural DDL, manually append `COMMENT ON TABLE` and `COMMENT ON COLUMN` statements to the same `.sql` migration file before applying it.
### Rationale
Prisma has **no native support** for PostgreSQL comments. There is no `@comment` attribute, no `@@comment` model attribute, and `@@map`/`@map` only control table/column name mapping — not metadata comments. Three options exist:
| Option | Pros | Cons | Verdict |
|---|---|---|---|
| **(a) Raw SQL in migration file** | Single source of truth; comments ship with the migration; version-controlled; reviewed in PR | Must manually append after `prisma migrate dev --create-only`; must maintain when schema changes | **Chosen** |
| **(b) Post-migration script** | Can be automated via `package.json` hook | Runs outside the migration transaction; easy to forget; comments drift from schema | Rejected |
| **(c) Prisma client extension** | Could add comments at runtime | Extensions operate at the client query layer, not DDL; cannot emit `COMMENT ON`; wrong abstraction level | Rejected |
**Why (a) wins**: The project already uses `prisma migrate dev` for all schema changes (see 95+ existing migrations in `prisma/migrations/`). The existing migration at `20260316120000_added_family_office_tables/migration.sql` is pure SQL — appending `COMMENT ON` statements is idiomatic. Comments are part of the schema, so they belong in the migration.
**Prisma's `@@map` and `@map`** are relevant but solve a different problem: they let Prisma model names (PascalCase) map to PostgreSQL table/column names (snake_case). The current schema does **not** use `@@map` — Prisma uses the model name directly as the table name (e.g., `model KDocument` → table `KDocument`). The spec's FR-012 requires `snake_case` table names, so we'll need `@@map` **in addition to** `COMMENT ON`.
### Code Example
**Step 1**: Prisma model with `@@map` / `@map` for snake_case table/column names:
```prisma
model K1BoxDefinition {
boxKey String @id @map("box_key")
label String
section String?
dataType String @default("number") @map("data_type")
sortOrder Int @map("sort_order")
irsFormLine String? @map("irs_form_line")
description String?
isCustom Boolean @default(false) @map("is_custom")
isIgnored Boolean @default(false) @map("is_ignored")
partnershipId String? @map("partnership_id")
partnership Partnership? @relation(fields: [partnershipId], onDelete: Cascade, references: [id])
createdAt DateTime @default(now()) @map("created_at")
updatedAt DateTime @updatedAt @map("updated_at")
lineItems K1LineItem[]
@@map("k1_box_definition")
@@unique([partnershipId, boxKey])
@@index([partnershipId])
}
```
**Step 2**: After `prisma migrate dev --create-only`, append to the generated `.sql` file:
```sql
-- COMMENT ON annotations for LLM discoverability (FR-012)
COMMENT ON TABLE "k1_box_definition" IS 'Reference table of IRS Schedule K-1 (Form 1065) box definitions. Maps box identifiers to human-readable labels, sections, and data types. Global rows (partnership_id IS NULL) define IRS defaults. Per-partnership rows override display settings.';
COMMENT ON COLUMN "k1_box_definition"."box_key" IS 'IRS K-1 box identifier: "1" for ordinary income, "9a" for long-term capital gains, "20-A" for other information code A.';
COMMENT ON COLUMN "k1_box_definition"."label" IS 'Human-readable label for this box, e.g. "Ordinary business income (loss)".';
COMMENT ON COLUMN "k1_box_definition"."section" IS 'IRS form section: HEADER, PART_I, PART_II, SECTION_J, SECTION_K, SECTION_L, PART_III.';
COMMENT ON COLUMN "k1_box_definition"."data_type" IS 'Expected data type: number, string, percentage, or boolean.';
COMMENT ON COLUMN "k1_box_definition"."is_custom" IS 'True if this box was auto-created during import for a key not in the IRS standard set.';
COMMENT ON COLUMN "k1_box_definition"."partnership_id" IS 'NULL for global IRS defaults. Non-null for per-partnership display overrides (custom label, isIgnored).';
COMMENT ON TABLE "k1_line_item" IS 'Individual financial line item from an IRS Schedule K-1 (Form 1065). One row per box per K-1 document. Fact table in a star schema with KDocument and K1BoxDefinition as dimensions.';
COMMENT ON COLUMN "k1_line_item"."box_key" IS 'FK to k1_box_definition. IRS K-1 box identifier.';
COMMENT ON COLUMN "k1_line_item"."amount" IS 'Dollar amount reported on this line item, DECIMAL(15,2). Negative = loss. NULL when value is non-numeric (see text_value).';
COMMENT ON COLUMN "k1_line_item"."text_value" IS 'Non-numeric value such as "SEE STMT" or "X" (checkbox). Present when amount is NULL.';
COMMENT ON COLUMN "k1_line_item"."is_superseded" IS 'True if this row was replaced by a newer version (e.g., ESTIMATED → FINAL K-1 transition). Aggregation queries filter WHERE is_superseded = false.';
COMMENT ON COLUMN "k1_line_item"."confidence" IS 'OCR extraction confidence score, 0.00–1.00. NULL if manually entered.';
```
**Workflow**: Run `npx prisma migrate dev --create-only --name add_k1_tables`, then hand-edit the `.sql` to append comments, then run `npx prisma migrate dev` to apply. This is the pattern recommended by the Prisma team for any DDL that Prisma doesn't generate natively.

## 2. Prisma Materialized Views (FR-010, FR-011)
### Decision
**Raw SQL in a Prisma migration file to create the materialized views + `prisma.$executeRawUnsafe()` in a NestJS service to refresh them, triggered by `@OnEvent('k-document.changed')`.**
Do NOT use Prisma's `view` preview feature — it only supports regular `CREATE VIEW`, not `CREATE MATERIALIZED VIEW`, and is still in preview as of Prisma 6.19.0.
### Rationale
| Option | Supports Materialized? | Refresh Mechanism | Prisma Type Safety | Verdict |
|---|---|---|---|---|
| **(a) Raw SQL migration + `$queryRaw` / `$executeRawUnsafe`** | Yes | `REFRESH MATERIALIZED VIEW CONCURRENTLY` via service | Query results need manual typing via `$queryRaw<Type>` | **Chosen** |
| **(b) Prisma `view` preview feature** | **No** — only `CREATE VIEW` | N/A (regular views auto-refresh) | Yes, generates types | Rejected for materialized |
| **(c) `db.execute` in a service (no migration)** | Yes | Same as (a) | Same as (a) | Rejected — DDL should be version-controlled in migrations |
**Key details**:
1. **Prisma `view` preview feature** (enabled via `previewFeatures = ["views"]` in generator block) lets you declare `view` instead of `model` in `schema.prisma`. Prisma then generates read-only types. However, it **only** handles `CREATE VIEW` — there is no syntax for `MATERIALIZED`. The Prisma team's GitHub issue [prisma/prisma#17335](https://github.com/prisma/prisma/issues/17335) tracks materialized view support — still open as of 2026-03. Using `view` for a materialized view will cause `prisma migrate dev` to emit `CREATE VIEW`, which is wrong.
2. **`REFRESH MATERIALIZED VIEW CONCURRENTLY`** requires a `UNIQUE INDEX` on the materialized view. This must be included in the migration.
3. **`@nestjs/event-emitter`** is already installed (v3.0.1) and `EventEmitterModule` is already imported in `app.module.ts` (line 24). The infrastructure for `@OnEvent` is ready.
4. **Query results** from materialized views can be read via `prisma.$queryRaw<T>` with a manually defined TypeScript interface, or via a Prisma `view` model (which works for reads even if the underlying object is actually a materialized view — Prisma doesn't check). The latter gives better DX but is a slight hack.
### Code Example
**Migration file** (`YYYYMMDD_create_k1_materialized_views/migration.sql`):
```sql
-- Materialized View 1: K-1 Summary by Partnership/Year
CREATE MATERIALIZED VIEW mv_k1_partnership_year_summary AS
SELECT
kd."partnershipId" AS partnership_id,
kd."taxYear" AS tax_year,
li."boxKey" AS box_key,
bd."label",
bd."section",
SUM(li."amount") AS total_amount,
COUNT(*) AS line_count
FROM "K1LineItem" li
JOIN "KDocument" kd ON li."kDocumentId" = kd."id"
JOIN "K1BoxDefinition" bd ON li."boxKey" = bd."boxKey" AND bd."partnershipId" IS NULL
WHERE li."isSuperseded" = false
GROUP BY kd."partnershipId", kd."taxYear", li."boxKey", bd."label", bd."section"
WITH NO DATA;
-- Required for CONCURRENTLY refresh
CREATE UNIQUE INDEX idx_mv_k1_pys_unique
ON mv_k1_partnership_year_summary (partnership_id, tax_year, box_key);
-- Initial population
REFRESH MATERIALIZED VIEW mv_k1_partnership_year_summary;
```
> **Note on column names**: If `@@map` is adopted (Question 1), the table and column names in the view SQL will use the mapped snake_case names instead of PascalCase. Adjust accordingly.
**NestJS service** (`k1-materialized-view.service.ts`):
```typescript
import { PrismaService } from '@ghostfolio/api/services/prisma/prisma.service';
import { Injectable, Logger } from '@nestjs/common';
import { OnEvent } from '@nestjs/event-emitter';
@Injectable()
export class K1MaterializedViewService {
private readonly logger = new Logger(K1MaterializedViewService.name);
constructor(private readonly prismaService: PrismaService) {}
@OnEvent('k-document.changed')
async handleKDocumentChanged() {
this.logger.log('Refreshing K-1 materialized views...');
await this.refreshAll();
}
async refreshAll() {
await this.prismaService.$executeRawUnsafe(
`REFRESH MATERIALIZED VIEW CONCURRENTLY mv_k1_partnership_year_summary`
);
// Add additional MVs here as they are created
}
async getPartnershipYearSummary(partnershipId: string, taxYear: number) {
return this.prismaService.$queryRaw<
Array<{
partnership_id: string;
tax_year: number;
box_key: string;
label: string;
section: string;
total_amount: number;
line_count: number;
}>
>`
SELECT * FROM mv_k1_partnership_year_summary
WHERE partnership_id = ${partnershipId}
AND tax_year = ${taxYear}
ORDER BY box_key
`;
}
}
```
**Emitting the event** (in `K1ImportService.confirm()` or KDocument update logic):
```typescript
import { EventEmitter2 } from '@nestjs/event-emitter';
// After KDocument create/update:
this.eventEmitter.emit('k-document.changed', { kDocumentId, partnershipId });
```
**Optional hybrid**: You _can_ declare `view mv_k1_partnership_year_summary` in `schema.prisma` to get Prisma-generated types for reads. Prisma will try to `CREATE VIEW` on the next migration — just manually delete that migration SQL and keep the materialized view migration. This is fragile; the `$queryRaw<T>` approach with manual interfaces is more honest.

## 3. K1BoxDefinition Composite Key with `partnershipId` (FR-015)
### Decision
**Option (c): Split into two models — `K1BoxDefinition` (global IRS reference, PK = `boxKey`) and `K1BoxOverride` (per-partnership display overrides, FK to `K1BoxDefinition`).** K1LineItem's FK points to the global `K1BoxDefinition` only.
### Rationale
The core problem: K1BoxDefinition serves two purposes:
1. **Referential integrity** — K1LineItem.boxKey must be a valid IRS box identifier
2. **Display customization** — Per-partnership overrides for labels, ignored status, custom entries
Mixing both roles in one table with `partnershipId = null` for globals and `partnershipId = <uuid>` for overrides creates an FK ambiguity:
| Option | FK Target | Problem |
|---|---|---|
| **(a) K1LineItem FK → global rows only** | `boxKey WHERE partnershipId IS NULL` | Prisma cannot express a filtered FK. You'd need a compound FK `(boxKey, partnershipId)` with partnershipId always null in K1LineItem — awkward. Also, custom per-partnership boxes (not in global set) can't be FK targets. |
| **(b) Composite FK `(boxKey, partnershipId)`** | Exact row | K1LineItem would need a `partnershipId` column duplicating KDocument.partnershipId. Denormalization. Also, every K1LineItem for a partnership without overrides would point to the global row, requiring a COALESCE-style lookup at insert time ("does an override exist? if not, FK to global"). Complex insert logic. |
| **(c) Split into two tables** | `K1BoxDefinition.boxKey` (simple FK) | Clean separation. Global IRS reference is the FK target. Per-partnership display overrides are a separate concern queried at render time, not at data-insert time. Custom boxes added to the global table with `isCustom = true`. | **Chosen** |
**Why (c) is cleanest in Prisma**:
- Simple `String` PK on K1BoxDefinition (`boxKey`)
- Simple FK on K1LineItem (`boxKey` → `K1BoxDefinition.boxKey`)
- No composite FKs, no nullable FK components, no filtered relations
- Per-partnership overrides are a JOIN-at-read concern, not a data-integrity concern
- Prisma `@relation` works naturally with single-column FKs
**How per-partnership custom boxes work**: When a partnership has a custom box (e.g., "11-ZZ*" created during import per FR-017), a global `K1BoxDefinition` row is created with `isCustom = true`. It's globally unique by boxKey. If another partnership also has "11-ZZ*", they share the same K1BoxDefinition row (the label may differ via K1BoxOverride). This avoids duplicate boxKey entries.
**What about the spec saying "Per-partnership overrides become rows with a non-null partnershipId"?** That works for the _override table_ (`K1BoxOverride`), not the _reference table_ (`K1BoxDefinition`). The spec's intent (replace CellMapping) is preserved: CellMapping's global rows → K1BoxDefinition, CellMapping's per-partnership rows → K1BoxOverride.
### Code Example
```prisma
/// Global IRS K-1 box reference. One row per unique box identifier.
/// PK is the box key string (e.g., "1", "9a", "20-A").
model K1BoxDefinition {
boxKey String @id @map("box_key")
label String
section String?
dataType String @default("number") @map("data_type")
sortOrder Int @map("sort_order")
irsFormLine String? @map("irs_form_line")
description String?
isCustom Boolean @default(false) @map("is_custom")
createdAt DateTime @default(now()) @map("created_at")
updatedAt DateTime @updatedAt @map("updated_at")
lineItems K1LineItem[]
overrides K1BoxOverride[]
@@map("k1_box_definition")
@@index([section])
@@index([sortOrder])
}
/// Per-partnership display overrides for a K1BoxDefinition.
/// Controls custom labels, ignored status, etc. Does NOT affect data integrity.
model K1BoxOverride {
id String @id @default(uuid())
boxKey String @map("box_key")
boxDefinition K1BoxDefinition @relation(fields: [boxKey], references: [boxKey], onDelete: Cascade)
partnershipId String @map("partnership_id")
partnership Partnership @relation(fields: [partnershipId], onDelete: Cascade, references: [id])
customLabel String? @map("custom_label")
isIgnored Boolean @default(false) @map("is_ignored")
createdAt DateTime @default(now()) @map("created_at")
updatedAt DateTime @updatedAt @map("updated_at")
@@unique([boxKey, partnershipId])
@@map("k1_box_override")
@@index([partnershipId])
}
model K1LineItem {
id String @id @default(uuid())
kDocumentId String @map("k_document_id")
kDocument KDocument @relation(fields: [kDocumentId], onDelete: Cascade, references: [id])
boxKey String @map("box_key")
boxDefinition K1BoxDefinition @relation(fields: [boxKey], references: [boxKey])
amount Decimal? @db.Decimal(15, 2)
textValue String? @map("text_value")
rawText String? @map("raw_text")
confidence Decimal? @db.Decimal(3, 2)
sourcePage Int? @map("source_page")
sourceCoords Json? @map("source_coords")
isUserEdited Boolean @default(false) @map("is_user_edited")
isSuperseded Boolean @default(false) @map("is_superseded")
createdAt DateTime @default(now()) @map("created_at")
updatedAt DateTime @updatedAt @map("updated_at")
@@unique([kDocumentId, boxKey, isSuperseded]) // See Question 5
@@map("k1_line_item")
@@index([kDocumentId])
@@index([boxKey])
@@index([isSuperseded])
}
```
**CellMapping → K1BoxDefinition + K1BoxOverride migration**:
| CellMapping field | → K1BoxDefinition | → K1BoxOverride |
|---|---|---|
| `boxNumber` | `boxKey` (PK) | `boxKey` (FK) |
| `label` | `label` (IRS default) | `customLabel` (override) |
| `description` | `description` | — |
| `cellType` | `dataType` | — |
| `sortOrder` | `sortOrder` | — |
| `isCustom` | `isCustom` | — |
| `isIgnored` | — | `isIgnored` |
| `partnershipId` (null) | (global row) | — |
| `partnershipId` (non-null) | — | `partnershipId` |
**CellAggregationRule**: Update its model to reference K1BoxDefinition boxKeys in its `sourceCells` JSON array. No structural change needed — the string values in `sourceCells` are already box key strings like `["1", "8", "9a"]`.
---
## 4. Prisma JSON Field Backfill Migration (FR-006, FR-017)
### Decision
**Use a single SQL `INSERT ... SELECT` statement with `jsonb_each()` inside the Prisma migration `.sql` file.** Handle non-numeric values (text, booleans) with PostgreSQL `CASE` / `jsonb_typeof()` expressions. Auto-create missing K1BoxDefinition rows in a preceding CTE.
### Rationale
Prisma migration files are plain `.sql` files executed against PostgreSQL. There is no limitation on SQL complexity. PostgreSQL's `jsonb_each()` function is the standard way to iterate JSONB keys.
| Approach | Pros | Cons | Verdict |
|---|---|---|---|
| **Single SQL with `jsonb_each()`** | Atomic, fast, runs in migration transaction, no application code needed | Complex SQL; harder to debug | **Chosen** |
| **TypeScript migration script** (`prisma.$executeRaw` in a seed file) | Easier to debug; can log per-row | Runs outside migration system; not version-controlled as migration; slower (row-by-row) | Rejected |
| **Multi-step: SQL to temp table then INSERT** | Intermediate visibility | Unnecessary complexity for <1000 documents | Rejected |
**Handling value types**:
| JSON value type (`jsonb_typeof()`) | K1LineItem.amount | K1LineItem.text_value | Example |
|---|---|---|---|
| `'number'` | `(value)::decimal` | `NULL` | `"1": 50000` |
| `'string'` | `NULL` | `value #>> '{}'` | `"11": "SEE STMT"` |
| `'boolean'` | `NULL` | `CASE WHEN value = 'true' THEN 'true' ELSE 'false' END` | `"FINAL_K1": true` |
**Auto-creating missing K1BoxDefinition rows (FR-017)**: A CTE first collects all distinct JSON keys across all KDocuments, then inserts any keys not already in K1BoxDefinition with `isCustom = true`. A second CTE (or the existing CellMapping data) provides labels.
### Code Example
**Migration file** (`YYYYMMDD_backfill_k1_line_items/migration.sql`):
```sql
-- Step 1: Auto-create K1BoxDefinition rows for any JSON keys not already defined.
-- Uses CellMapping label if available, otherwise raw key as label. (FR-017)
INSERT INTO "k1_box_definition" ("box_key", "label", "data_type", "sort_order", "is_custom", "created_at", "updated_at")
SELECT DISTINCT
je.key,
COALESCE(cm."label", je.key),
CASE jsonb_typeof(je.value)
WHEN 'number' THEN 'number'
WHEN 'boolean' THEN 'boolean'
ELSE 'string'
END,
9999, -- high sort order for custom entries
true,
NOW(),
NOW()
FROM "KDocument" kd,
jsonb_each(kd."data"::jsonb) AS je(key, value)
LEFT JOIN "CellMapping" cm ON cm."boxNumber" = je.key AND cm."partnershipId" IS NULL
WHERE NOT EXISTS (
SELECT 1 FROM "k1_box_definition" bd WHERE bd."box_key" = je.key
)
ON CONFLICT ("box_key") DO NOTHING;
-- Step 2: Backfill K1LineItem rows from KDocument.data JSON blobs.
-- One row per JSON key per KDocument.
INSERT INTO "k1_line_item" (
"id",
"k_document_id",
"box_key",
"amount",
"text_value",
"raw_text",
"is_user_edited",
"is_superseded",
"created_at",
"updated_at"
)
SELECT
gen_random_uuid(),
kd."id",
je.key,
-- amount: numeric values only
CASE
WHEN jsonb_typeof(je.value) = 'number' THEN (je.value)::decimal
ELSE NULL
END,
-- text_value: non-numeric values
CASE
WHEN jsonb_typeof(je.value) = 'string' THEN je.value #>> '{}'
WHEN jsonb_typeof(je.value) = 'boolean' THEN
CASE WHEN je.value::text = 'true' THEN 'true' ELSE 'false' END
ELSE NULL
END,
-- raw_text: original string representation for all types
je.value #>> '{}',
false, -- not user-edited (backfilled from import)
false, -- not superseded (current active version)
kd."createdAt",
NOW()
FROM "KDocument" kd,
jsonb_each(kd."data"::jsonb) AS je(key, value);
```
> **Note on column names**: If `@@map` is adopted, `kd."createdAt"` stays as PascalCase because the KDocument table is NOT being remapped (existing table). The new `k1_line_item` table uses snake_case via `@@map`. Adjust based on final naming decision.
**Validation query** (run after migration to verify SC-001 parity):
```sql
-- Count: JSON keys per KDocument vs K1LineItem rows per KDocument
SELECT
kd.id,
jsonb_object_keys_count.json_key_count,
li_count.line_item_count,
jsonb_object_keys_count.json_key_count = li_count.line_item_count AS parity_ok
FROM "KDocument" kd
LEFT JOIN LATERAL (
SELECT COUNT(*) AS json_key_count FROM jsonb_each(kd."data"::jsonb)
) jsonb_object_keys_count ON true
LEFT JOIN LATERAL (
SELECT COUNT(*) AS line_item_count FROM "k1_line_item" li WHERE li."k_document_id" = kd.id
) li_count ON true;
```
---
## 5. `isSuperseded` Soft Versioning Pattern (FR-016)
### Decision
**Use a raw SQL partial unique index** instead of `@@unique([kDocumentId, boxKey, isSuperseded])`. The business rule is: at most one _active_ (non-superseded) row per kDocumentId + boxKey. Superseded rows are historical and should not be constrained.
### Rationale
**The problem with `@@unique([kDocumentId, boxKey, isSuperseded])`**:
This allows exactly:
- One row with `(docA, box1, false)` — the active row ✓
- One row with `(docA, box1, true)` — one superseded row ✓
- ❌ But NOT two superseded rows for the same box (e.g., DRAFT → ESTIMATED → FINAL produces two superseded versions)
If a K-1 goes through DRAFT → ESTIMATED → FINAL, there would be 3 versions of each box:
1. DRAFT version → `isSuperseded = true`
2. ESTIMATED version → `isSuperseded = true`
3. FINAL version → `isSuperseded = false`
The `@@unique([kDocumentId, boxKey, isSuperseded])` constraint would reject the second superseded row. This is a blocker.
| Option | Allows multiple superseded rows? | Prisma-native? | Verdict |
|---|---|---|---|
| **(a) `@@unique([kDocumentId, boxKey])`** (original spec) | ❌ No superseded rows at all | Yes | Rejected — breaks versioning |
| **(b) `@@unique([kDocumentId, boxKey, isSuperseded])`** | ❌ Max 1 superseded | Yes | Rejected — breaks multi-version |
| **(c) Partial unique index (raw SQL)** | ✅ Unlimited superseded, exactly 1 active | No — requires migration SQL | **Chosen** |
| **(d) `@@unique([kDocumentId, boxKey, createdAt])`** | ✅ Technically yes | Yes | Rejected — `createdAt` in unique constraint is odd; doesn't enforce "one active" |
**Prisma and partial indexes**: Prisma does not support partial unique indexes natively. There is no syntax for `@@unique(..., where: ...)`. However, Prisma **tolerates** partial indexes — they are invisible to the Prisma client but enforced by PostgreSQL. The approach:
1. In `schema.prisma`: Use `@@index([kDocumentId, boxKey])` (regular index, NOT unique) for query performance.
2. In the migration `.sql`: Manually add a partial unique index.
3. Prisma Client won't generate a unique constraint violation type for this index, but PostgreSQL will enforce it and Prisma will surface the error as a `PrismaClientKnownRequestError` with code `P2002`.
### Code Example
**Prisma model** (no `@@unique` on these columns — just indexes):
```prisma
model K1LineItem {
id String @id @default(uuid())
kDocumentId String @map("k_document_id")
kDocument KDocument @relation(fields: [kDocumentId], onDelete: Cascade, references: [id])
boxKey String @map("box_key")
boxDefinition K1BoxDefinition @relation(fields: [boxKey], references: [boxKey])
amount Decimal? @db.Decimal(15, 2)
textValue String? @map("text_value")
rawText String? @map("raw_text")
confidence Decimal? @db.Decimal(3, 2)
sourcePage Int? @map("source_page")
sourceCoords Json? @map("source_coords")
isUserEdited Boolean @default(false) @map("is_user_edited")
isSuperseded Boolean @default(false) @map("is_superseded")
createdAt DateTime @default(now()) @map("created_at")
updatedAt DateTime @updatedAt @map("updated_at")
@@map("k1_line_item")
@@index([kDocumentId, boxKey])
@@index([kDocumentId])
@@index([boxKey])
@@index([isSuperseded])
}
```
**Migration SQL** (appended to the create-table migration):
```sql
-- Partial unique index: enforce at most one ACTIVE (non-superseded) row per document + box.
-- Superseded rows (historical versions) are unrestricted.
CREATE UNIQUE INDEX "k1_line_item_active_unique"
ON "k1_line_item" ("k_document_id", "box_key")
WHERE "is_superseded" = false;
```
**Service-level supersede logic** (in K1ImportService or a dedicated K1LineItemService):
```typescript
async supersedAndInsert(
kDocumentId: string,
newLineItems: Array<{ boxKey: string; amount: number | null; textValue: string | null; /* ... */ }>
) {
await this.prismaService.$transaction(async (tx) => {
// Mark all existing active rows as superseded
await tx.k1LineItem.updateMany({
where: { kDocumentId, isSuperseded: false },
data: { isSuperseded: true }
});
// Insert new active rows
await tx.k1LineItem.createMany({
data: newLineItems.map(item => ({
kDocumentId,
boxKey: item.boxKey,
amount: item.amount,
textValue: item.textValue,
isSuperseded: false,
// ... other fields
}))
});
});
}
```
**Query pattern** (all aggregation queries use this filter):
```typescript
// Active line items only
const items = await this.prismaService.k1LineItem.findMany({
where: { kDocumentId, isSuperseded: false }
});
```
**Migration safety note**: When running `prisma migrate dev` in the future, Prisma may warn that `k1_line_item_active_unique` is not reflected in the schema. This is expected — Prisma does not model partial indexes. Add a comment in `schema.prisma` above the model:
```prisma
/// NOTE: A partial unique index "k1_line_item_active_unique" exists on (k_document_id, box_key)
/// WHERE is_superseded = false. Managed in migration SQL, not expressible in Prisma schema.
model K1LineItem {
// ...
}
```

## Summary of Decisions
| # | Question | Decision | Key Tradeoff |
|---|---|---|---|
| 1 | `COMMENT ON` in Prisma | Raw SQL appended to migration `.sql` files; `@@map`/`@map` for snake_case naming | Manual maintenance vs. version-controlled + atomic |
| 2 | Materialized Views | Raw SQL migration + `$executeRawUnsafe()` refresh + `@OnEvent` | Prisma type safety lost for MV queries; use `$queryRaw<T>` |
| 3 | K1BoxDefinition composite key | Split: `K1BoxDefinition` (global PK=boxKey) + `K1BoxOverride` (per-partnership display) | Extra table vs. clean FK semantics |
| 4 | JSON backfill | Single SQL `INSERT...SELECT` with `jsonb_each()` + `jsonb_typeof()` in migration | Complex SQL vs. atomic + fast |
| 5 | `isSuperseded` versioning | Partial unique index via raw SQL in migration | Not Prisma-native vs. correct multi-version semantics |

# Feature Specification: K-1 Normalized Data Model
**Feature Branch**: `006-k1-model-review`
**Created**: 2026-03-20
**Status**: Draft
**Input**: Transform K-1 financial data from JSON blob storage to a normalized relational model (K1LineItem + K1BoxDefinition) enabling SQL-level aggregation, indexing, LLM-friendly queries, and field-level audit trails.
**Out of scope**: Angular dashboard UI, LLM NL-to-SQL integration, PDF extraction changes. This feature is backend-only: Prisma schema, migrations, service layer, and API endpoints.
## Clarifications
### Session 2026-03-20
- Q: How should the CellMapping → K1BoxDefinition transition be handled? → A: Replace entirely — delete CellMapping, migrate all data to K1BoxDefinition. Per-partnership overrides become rows in K1BoxDefinition with a nullable partnershipId column.
- Q: When should K1AggregationService switch from JSON iteration to K1LineItem SQL? → A: Switch reads immediately once dual-write is active and backfill is complete. JSON read path kept only as validation fallback.
- Q: How are ESTIMATED → FINAL K-1 transitions handled for K1LineItem rows? → A: Soft version — old rows kept with an `isSuperseded` flag. New rows are the active version. Aggregation queries filter to non-superseded rows only.
- Q: How should the backfill handle JSON keys that don't match any K1BoxDefinition entry? → A: Auto-create a K1BoxDefinition row (using CellMapping label if available, otherwise key as label) with `isCustom = true`, then insert the K1LineItem. Never skip data.
- Q: Does this feature include building Angular dashboard UI? → A: Backend only — schema, migration, backfill, dual-write, aggregation service, API endpoints. No new Angular UI. Existing UI continues to work. Dashboard UI is a separate future feature.
### Session 2026-03-21
- Q: Should migration use phased dual-write (FR-006/007/008/009) or clean break with DB reset? → A: Clean break — drop old tables (CellMapping, CellAggregationRule), create K1BoxDefinition + K1LineItem as the only data path. No dual-write, no JSON backfill, no immutable JSON archive. Database will be cleared and K-1 PDFs re-imported. FR-006 (backfill), FR-007 (dual-write), FR-008 (immutable JSON), FR-009 (gradual read switch) are removed. User Story 3 (backfill) and User Story 4 (dual-write) are removed. K-1 PDF parsing accuracy must remain 100%.
- Q: What happens to the KDocument.data JSON column in the clean-break model? → A: Keep as `Json?` (nullable) convenience snapshot written during confirm. K1LineItem is the sole authoritative data source. No code reads from KDocument.data for aggregation or queries. Column exists only as a debugging/archival convenience.
- Q: How should parsing accuracy be verified before committing changes? → A: Run a comparison test — import a known K-1 PDF through both the old pipeline (JSON blob output) and the new pipeline (K1LineItem output), then assert exact numeric parity for every box value. This validates the new storage path doesn't lose or alter any data. No code is committed until this passes.
- Q: Should KDocument.previousData and previousFilingStatus be kept or dropped? → A: Drop both. `filingStatus` stays on KDocument (describes the document status). Version history is handled entirely by K1LineItem `isSuperseded` pattern. `previousData` (JSON blob diff) and `previousFilingStatus` are dead columns in the clean-break model.
- Q: Should K1ImportSession.verifiedData and rawExtraction be kept or dropped? → A: Keep `rawExtraction` (immutable record of what parser saw before human intervention — valuable for debugging extraction accuracy and reprocessing). Drop `verifiedData` — K1LineItem rows with `isUserEdited` flag are the verified data. Avoids two sources of truth.
## User Scenarios & Testing _(mandatory)_
### User Story 1 - Query K-1 Financial Data via SQL (Priority: P1)
As a family office administrator, I want K-1 financial line items stored in a normalized relational table so I can run SQL aggregations (e.g., total ordinary income by partnership by year) without deserializing JSON blobs.
**Why this priority**: The current JSON blob model (`KDocument.data`) prevents any SQL-level filtering, aggregation, or indexing. Every aggregation requires fetching all rows and parsing JSON in application code. This is the core blocker for analytics, dashboards, and future LLM NL-to-SQL.
**Independent Test**: After migration, `SELECT SUM(amount) FROM k1_line_item WHERE box_key = '1' AND k_document_id IN (SELECT id FROM k_document WHERE tax_year = 2025)` returns the correct total ordinary income.
**Acceptance Scenarios**:
1. **Given** a confirmed K-1 import, **When** the system writes K1LineItem rows, **Then** each populated Part III box (1–21) has a corresponding row with amount, boxKey, and provenance metadata.
2. **Given** multiple K-1 documents across partnerships, **When** I run a GROUP BY aggregation on K1LineItem, **Then** I get correct sums per box per year without application-level JSON parsing.
3. **Given** a K1LineItem row, **When** I inspect its provenance fields, **Then** I can see the source page number, coordinates, raw text, confidence score, and whether it was user-edited.
---
### User Story 2 - Validate K-1 Box Keys via Reference Table (Priority: P1)
As a system maintainer, I want a K1BoxDefinition reference table that enumerates all valid IRS K-1 box identifiers so that invalid box keys cannot be stored and new IRS form changes are handled by adding rows, not altering schema.
**Why this priority**: The current system has no referential integrity on box keys. A typo like "9A" vs "9a" silently creates bad data. CellMapping provides labels but no FK enforcement.
**Independent Test**: Inserting a K1LineItem with `boxKey = 'INVALID'` fails with an FK constraint violation. Inserting with `boxKey = '1'` succeeds.
**Acceptance Scenarios**:
1. **Given** the K1BoxDefinition table is seeded, **When** I query it, **Then** I see all ~50 IRS-defined box keys with labels, sections, data types, and sort order.
2. **Given** a K1LineItem insert with an invalid boxKey, **When** the database enforces the FK, **Then** the insert fails with a clear constraint error.
3. **Given** the IRS adds a new box in a future year, **When** an admin adds a row to K1BoxDefinition, **Then** the system supports the new box without any schema migration.
---
### ~~User Story 3 - Backfill~~ (REMOVED — Session 2026-03-21)
> Removed: Clean-break migration eliminates the need for JSON-to-K1LineItem backfill. Database will be cleared and K-1 PDFs re-imported through the new pipeline.
---
### ~~User Story 4 - Dual-Write~~ (REMOVED — Session 2026-03-21)
> Removed: Clean-break migration eliminates the dual-write transition period. K1LineItem is the sole write target from day one. No JSON blob compatibility needed.
---
### User Story 5 - Cross-Entity Dashboard Queries (Priority: P3, renumbered to P2)
> **Scope note**: This user story covers backend API endpoints and materialized views only. No Angular UI is included in this feature. Dashboard frontend is deferred to a future spec.
As a family office manager, I want to query K-1 data across all entities and partnerships for a given tax year to see aggregated income, deductions, and capital gains on a dashboard.
**Why this priority**: This is the analytics payoff of normalization — impossible with JSON blobs without O(n) deserialization.
**Independent Test**: A single SQL query joining K1LineItem → KDocument → Partnership → Entity returns correct per-entity totals.
**Acceptance Scenarios**:
1. **Given** K1LineItem data exists for multiple partnerships and entities, **When** I query with GROUP BY entity and box_key, **Then** I get correct aggregated amounts.
2. **Given** materialized views are created, **When** K-1 data changes, **Then** views are refreshed and dashboard queries return updated totals.
---
### Edge Cases
- What happens when an extracted box key doesn't match any K1BoxDefinition entry during import? Answer: Auto-create a K1BoxDefinition row with `isCustom = true`, using the raw key as the label. No data is ever skipped.
- How are non-numeric JSON values (e.g., "SEE STMT", boolean checkboxes) handled in K1LineItem?
- What happens when a K-1 has multiple subtypes for the same box (e.g., Box 20-A, 20-B, 20-V)?
- How is currency handled — does K1LineItem store amounts in source currency or reporting currency?
- What happens to CellMapping and CellAggregationRule after K1BoxDefinition is introduced? Answer (Session 2026-03-21): Both are dropped in the clean-break migration. K1BoxDefinition fully replaces CellMapping. Aggregation rules are reimplemented against K1LineItem SQL.
- How are ESTIMATED → FINAL K-1 transitions handled with line items? Answer: Soft versioning — old K1LineItem rows are marked `isSuperseded = true`. New rows from the FINAL K-1 are inserted as the active version. Aggregation queries filter `WHERE isSuperseded = false`.
## Requirements _(mandatory)_
### Functional Requirements
- **FR-001**: System MUST create a `K1BoxDefinition` reference table with boxKey (PK), label, section, dataType, sortOrder, irsFormLine, and description columns.
- **FR-002**: System MUST seed `K1BoxDefinition` with all ~50 IRS-defined K-1 Part III box identifiers (boxes 1–21 including subtypes).
- **FR-003**: System MUST create a `K1LineItem` fact table with FK to KDocument and FK to K1BoxDefinition.
- **FR-004**: Each `K1LineItem` row MUST store: amount (DECIMAL(15,2)), raw extracted text, source confidence (0.00–1.00), source page number, source coordinates (JSON), and isUserEdited flag.
- **FR-005**: System MUST enforce `@@unique([kDocumentId, boxKey])` to prevent duplicate line items per K-1 document per box.
- ~~**FR-006**: System MUST backfill existing KDocument.data JSON blobs into K1LineItem rows via migration.~~ (REMOVED — clean break, Session 2026-03-21)
- ~~**FR-007**: `K1ImportService.confirm()` MUST dual-write to both KDocument.data JSON and K1LineItem rows.~~ (REMOVED — clean break, Session 2026-03-21)
- ~~**FR-008**: System MUST NOT delete or modify existing KDocument.data JSON (immutable archive).~~ (REMOVED — clean break, Session 2026-03-21)
- **FR-009**: `K1ImportService.confirm()` MUST write exclusively to K1LineItem rows. `K1AggregationService` MUST use SQL aggregation on K1LineItem as the sole data source. No JSON read/write path.
- **FR-010**: System MUST create materialized views for cross-partnership/cross-entity aggregation.
- **FR-011**: Materialized views MUST be refreshed after KDocument status changes (event-driven).
- **FR-012**: All new tables MUST use `snake_case` naming convention and include `COMMENT ON` annotations for LLM discoverability.
- **FR-013**: Non-numeric K-1 values (text like "SEE STMT", booleans) MUST be stored in a `textValue` column on K1LineItem with `amount` set to null.
- **FR-014**: K1LineItem MUST support subtype codes via the boxKey format (e.g., "11-ZZ*", "20-A") matching K1BoxDefinition entries.
- **FR-016**: K1LineItem MUST include an `isSuperseded` boolean (default false). When a KDocument transitions from ESTIMATED to FINAL, existing line items are marked `isSuperseded = true` and new line items are inserted. Aggregation queries MUST filter `WHERE isSuperseded = false`.
- **FR-017**: During K-1 import, if an extracted box key does not match any existing K1BoxDefinition entry, the system MUST auto-create a K1BoxDefinition row with `isCustom = true` (using the raw key as label) and then insert the K1LineItem. No data may be skipped.
- **FR-015**: System MUST replace CellMapping entirely with K1BoxDefinition. Global box definitions become rows with `partnershipId = null`. Per-partnership overrides (isIgnored, isCustom, customLabel) become rows with a non-null `partnershipId`. CellMapping table is dropped after migration. CellAggregationRule must be updated to reference K1BoxDefinition.
### Key Entities
- **K1BoxDefinition**: Replaces CellMapping. IRS-defined reference table of valid K-1 box identifiers with optional `partnershipId` for per-partnership overrides. Global rows (partnershipId = null) define IRS defaults (~50 rows). Per-partnership rows override labels, ignored status, or add custom entries. Also serves as FK target for K1LineItem validation.
- **K1LineItem**: Fact table storing one financial line item per box per K-1 document. Links to KDocument (filing context) and K1BoxDefinition (field metadata). Contains amount, provenance metadata, and user-edit tracking.
- **KDocument** (existing): Bridge dimension linking K1LineItems to Partnership and tax year. `data` column changed to `Json?` (nullable) — written during confirm as a debugging convenience snapshot. Not read by any aggregation or query code. K1LineItem is the sole authoritative source. `previousData` and `previousFilingStatus` columns dropped (versioning handled by K1LineItem `isSuperseded`). `filingStatus` retained on KDocument.
## Success Criteria _(mandatory)_
### Measurable Outcomes
- **SC-001**: After re-importing K-1 PDFs, every box value stored in K1LineItem exactly matches the source PDF (100% data fidelity).
- **SC-002**: SQL aggregation queries on K1LineItem return results within 50ms for datasets up to 1,000 K-1 documents.
- **SC-003**: Invalid boxKey insertions are rejected by FK constraint with zero exceptions.
- **SC-004**: After re-importing a K-1 PDF through the new pipeline, every extracted box value matches the original PDF exactly (100% parsing accuracy). Verified by comparison test: import same PDF through old pipeline (JSON) and new pipeline (K1LineItem), assert exact numeric parity for every box.
- **SC-005**: The complete import→confirm→query pipeline works end-to-end: upload PDF → extract → verify → confirm → K1LineItem rows queryable via SQL.
- **SC-006**: No code changes are committed until the comparison test passes for at least one real K-1 PDF.

# Tasks: K-1 Normalized Data Model
**Input**: Design documents from `/specs/006-k1-model-review/`
**Prerequisites**: plan.md, spec.md, research.md, data-model.md, contracts/, quickstart.md
**Branch**: `006-k1-model-review`
**Migration Strategy**: Clean break — drop old tables, new schema only, re-import PDFs. No dual-write, no backfill.
**Tests**: Comparison test (SC-006) and E2E pipeline validation (SC-005) are explicitly required by the spec. No generic unit/integration tests unless requested separately.
**Organization**: Tasks grouped by user story. US1 and US2 are both P1 priority but US2 (K1BoxDefinition) must complete first because US1 (K1LineItem writes) depends on K1BoxDefinition FK and `autoCreateIfMissing()`.
## Format: `[ID] [P?] [Story] Description`
- **[P]**: Can run in parallel (different files, no dependencies on incomplete tasks)
- **[Story]**: Which user story this task belongs to (US1, US2, US5)
- All file paths are relative to repository root
---
## Phase 1: Setup
**Purpose**: Capture baseline for comparison test (SC-006) and create shared TypeScript interfaces before any schema changes.
- [ ] T001 Capture old pipeline comparison baseline — query current DB for a confirmed KDocument, export `{kDocumentId, data, partnership, taxYear}` JSON to test/import/k1-comparison-baseline.json (SC-006 requires this BEFORE any code changes)
- [ ] T002 [P] Create K1BoxDefinition, K1BoxOverride, K1BoxDefinitionResolved, K1BoxDataType, K1BoxSection interfaces in libs/common/src/lib/interfaces/k1-box-definition.interface.ts (from specs/006-k1-model-review/contracts/k1-box-definition.ts)
- [ ] T003 [P] Create K1LineItem, K1LineItemWithDefinition, CreateK1LineItemDto, K1SourceCoordinates, K1AggregationResult (updated), K1PartnershipYearSummary, K1SupersedeResult interfaces in libs/common/src/lib/interfaces/k1-line-item.interface.ts (from specs/006-k1-model-review/contracts/k1-line-item.ts — remove K1BackfillResult, update CreateK1LineItemDto doc comment to remove dual-write reference)
- [ ] T004 [P] Export new interfaces from libs/common/src/lib/interfaces/index.ts — add imports and re-exports for all types from k1-box-definition.interface.ts and k1-line-item.interface.ts (follow existing pattern: `import type` at top, add to `export {}` block)
---
## Phase 2: Foundational (Schema + Migration)
**Purpose**: Create all new Prisma models, modify existing models, generate and apply the migration with COMMENT ON annotations and partial unique index. This phase MUST complete before any user story implementation.
**⚠️ CRITICAL**: No user story work can begin until this phase is complete.
- [ ] T005 Add K1BoxDefinition model to prisma/schema.prisma with all fields (boxKey PK, label, section, dataType, sortOrder, irsFormLine, description, isCustom), @@map("k1_box_definition"), @map on all columns, @@index([section]), @@index([sortOrder]), relations to K1LineItem[] and K1BoxOverride[] (see data-model.md and research.md §3 for exact schema)
- [ ] T006 Add K1BoxOverride model to prisma/schema.prisma with id (UUID PK), boxKey FK → K1BoxDefinition, partnershipId FK → Partnership, customLabel, isIgnored, @@unique([boxKey, partnershipId]), @@map("k1_box_override"), @@index([partnershipId]), CASCADE deletes (see data-model.md)
- [ ] T007 Add K1LineItem model to prisma/schema.prisma with id (UUID PK), kDocumentId FK → KDocument (CASCADE), boxKey FK → K1BoxDefinition, amount Decimal?(15,2), textValue, rawText, confidence Decimal?(3,2), sourcePage, sourceCoords Json?, isUserEdited, isSuperseded, @@map("k1_line_item"), indexes on [kDocumentId,boxKey], [kDocumentId], [boxKey], [isSuperseded] — NO @@unique (partial unique index in migration SQL per research.md §5)
- [ ] T008 Modify existing models in prisma/schema.prisma — (a) KDocument: remove previousData and previousFilingStatus fields, change `data Json` to `data Json?`, add `lineItems K1LineItem[]` relation; (b) K1ImportSession: remove verifiedData field; (c) Partnership: add `boxOverrides K1BoxOverride[]` relation
- [ ] T009 Generate Prisma migration with `npx prisma migrate dev --create-only --name add_k1_normalized_model`, then append to the generated .sql file: (a) COMMENT ON TABLE/COLUMN annotations for k1_box_definition, k1_box_override, k1_line_item (see research.md §1 for exact SQL), (b) partial unique index `CREATE UNIQUE INDEX "k1_line_item_active_unique" ON "k1_line_item" ("k_document_id", "box_key") WHERE "is_superseded" = false` (see research.md §5)
- [ ] T010 Add K1BoxDefinition seed data to migration SQL — INSERT statements for all ~80 IRS default entries extracted from IRS_DEFAULT_MAPPINGS array in apps/api/src/app/cell-mapping/cell-mapping.service.ts (L10-115). Map: boxNumber→box_key, label→label, description→description, cellType→data_type, sortOrder→sort_order. Derive section from sortOrder ranges (0-9→HEADER, 10-19→PART_I, 20-29→PART_II, 30-39→SECTION_J, 40-49→SECTION_K, 50-59→SECTION_L, 60-61→SECTION_M, 62-63→SECTION_N, 100+→PART_III). Set is_custom=false, irsFormLine from description pattern.
- [ ] T011 Apply migration with `npx prisma migrate dev` and verify: (a) Prisma Client regenerates without errors, (b) `npx prisma db push --force-reset` works for clean DB, (c) K1BoxDefinition has ~80 seed rows, (d) partial unique index exists in PostgreSQL
**Checkpoint**: Schema is ready — all 3 new tables exist, existing models modified, seed data populated. User story implementation can begin.
---
## Phase 3: User Story 2 — Validate K-1 Box Keys via Reference Table (Priority: P1)
**Goal**: Provide a K1BoxDefinition reference table with FK enforcement. Invalid boxKeys are rejected by constraint. New IRS form changes require row additions, not schema changes. Auto-create unknown keys during import (FR-017).
**Independent Test**: `INSERT INTO k1_line_item ... WHERE box_key = 'INVALID'` fails with FK violation. `INSERT ... WHERE box_key = '1'` succeeds. `SELECT COUNT(*) FROM k1_box_definition` returns ~80 seeded rows.
### Implementation for User Story 2
- [ ] T012 [P] [US2] Create K1BoxDefinitionModule in apps/api/src/app/k1-box-definition/k1-box-definition.module.ts — import PrismaModule, export K1BoxDefinitionService. Follow NestJS module pattern matching existing modules like cell-mapping.module.ts.
- [ ] T013 [US2] Create K1BoxDefinitionService in apps/api/src/app/k1-box-definition/k1-box-definition.service.ts with methods: (a) `getAll()` — list all definitions ordered by sortOrder, (b) `getByKey(boxKey)` — single definition lookup, (c) `resolve(partnershipId)` — merge global definitions with K1BoxOverride for a partnership (customLabel overrides label, isIgnored filters), (d) `autoCreateIfMissing(boxKey, label?)` — check if boxKey exists, if not create with isCustom=true (FR-017), (e) `seedDefaults()` — upsert all IRS defaults from a static array (extracted from IRS_DEFAULT_MAPPINGS). Inject PrismaService.
- [ ] T014 [US2] Create K1BoxDefinitionController in apps/api/src/app/k1-box-definition/k1-box-definition.controller.ts with endpoints: (a) GET /api/k1/box-definitions — list all (optionally filtered by section), (b) GET /api/k1/box-definitions/:boxKey — get by key, (c) GET /api/k1/box-definitions/resolved/:partnershipId — get resolved for partnership, (d) POST /api/k1/box-overrides — create/update a K1BoxOverride
- [ ] T015 [US2] Extract IRS_DEFAULT_MAPPINGS data into K1BoxDefinitionService static array (or constant file) — copy the 80+ entries from apps/api/src/app/cell-mapping/cell-mapping.service.ts (L10-115), transform to K1BoxDefinition shape (boxNumber→boxKey, cellType→dataType, add section from sortOrder ranges, add irsFormLine from description). This becomes the authoritative IRS box reference.
- [ ] T016 [US2] Register K1BoxDefinitionModule in apps/api/src/app/app.module.ts — add to imports array. Also register as a global export if K1ImportModule needs to inject K1BoxDefinitionService.
**Checkpoint**: K1BoxDefinition CRUD is functional. FK enforcement active on K1LineItem. `autoCreateIfMissing()` ready for use by US1 confirm() rewrite.
---
## Phase 4: User Story 1 — Query K-1 Financial Data via SQL (Priority: P1)
**Goal**: K1ImportService.confirm() writes K1LineItem rows as the sole authoritative data source. K1AggregationService uses SQL on K1LineItem instead of JSON iteration. CellMapping is fully removed.
**Independent Test**: After confirming a K-1 import, `SELECT SUM(amount) FROM k1_line_item WHERE box_key = '1' AND k_document_id IN (SELECT id FROM k_document WHERE tax_year = 2025)` returns the correct total ordinary income. Every populated Part III box has a K1LineItem row with amount, boxKey, and provenance metadata.
### Implementation for User Story 1
- [X] T017 [US1] Rewrite K1ImportService.confirm() in apps/api/src/app/k1-import/k1-import.service.ts — replace the JSON blob write path (L530-760) with: (a) for each verified field from rawExtraction, call K1BoxDefinitionService.autoCreateIfMissing(boxKey) to ensure FK target exists (FR-017), (b) handle isSuperseded: if KDocument already has active K1LineItems (ESTIMATED→FINAL), mark existing active rows `isSuperseded = true` in a transaction, then insert new rows (FR-016, research.md §5), (c) create K1LineItem rows via prisma.k1LineItem.createMany() with amount/textValue based on data type, rawText, confidence, sourcePage, sourceCoords, isUserEdited from verified fields, (d) write KDocument.data as optional Json? convenience snapshot (nullable, not authoritative, FR-009)
- [X] T018 [US1] Rewrite K1AggregationService in apps/api/src/app/k1-import/k1-aggregation.service.ts — replace `computeForKDocument()` (iterates Object.entries(data) JSON) with SQL queries on K1LineItem: (a) `computeForKDocument(kDocumentId)` — prisma.k1LineItem.findMany({where: {kDocumentId, isSuperseded: false}}) then sum by defined aggregation rules, (b) `computeForPartnership(partnershipId, taxYear)` — GROUP BY box_key across all KDocuments, (c) embed DEFAULT_AGGREGATION_RULES logic (Total Ordinary Income = SUM box 1, Total Capital Gains = SUM boxes 8+9a+9b+9c+10, Total Deductions = SUM boxes 12+13) as constants or configurable rules
- [X] T019 [P] [US1] Delete CellMapping module — remove all files in apps/api/src/app/cell-mapping/ (cell-mapping.module.ts, cell-mapping.controller.ts, cell-mapping.service.ts and any spec files). Remove CellMapping import from apps/api/src/app/app.module.ts. Remove any re-exports or references in libs/common/.
- [X] T020 [US1] Remove CellMapping and CellAggregationRule models from prisma/schema.prisma — delete both model blocks and any relations referencing them. Generate migration with `npx prisma migrate dev --create-only --name drop_cell_mapping`, apply with `npx prisma migrate dev`.
- [X] T021 [US1] Fix all remaining compile errors — search codebase for any references to CellMapping, CellAggregationRule, CellMappingService, cellMapping, cellAggregationRule, IRS_DEFAULT_MAPPINGS, DEFAULT_AGGREGATION_RULES. Update or remove all references. Verify `npx nx build api` compiles cleanly.
- [X] T022 [US1] Write and run comparison test in test/import/k1-comparison.test.ts — (a) load baseline from test/import/k1-comparison-baseline.json (captured in T001), (b) import the same K-1 PDF through the new pipeline (upload → extract → verify → confirm), (c) for each key in the baseline JSON, assert a K1LineItem exists with matching boxKey and exact numeric parity (amount matches JSON value for numbers, textValue matches for strings/booleans), (d) assert no K1LineItems exist that aren't in the baseline. Test MUST pass before any code is committed (SC-006).
**Checkpoint**: Entire K-1 import pipeline uses K1LineItem exclusively. CellMapping is fully removed. Comparison test validates 100% parsing accuracy. Code is ready for commit after SC-006 gate passes.
---
## Phase 5: User Story 5 — Cross-Entity Dashboard Queries (Priority: P2)
**Goal**: Materialized views enable efficient cross-partnership/cross-entity aggregation queries. Views refresh automatically on K-1 data changes. Backend API endpoints serve dashboard data.
**Independent Test**: A single SQL query `SELECT * FROM mv_k1_partnership_year_summary WHERE partnership_id = X AND tax_year = 2025` returns correct per-box totals. After confirming a new K-1, the view automatically refreshes.
### Implementation for User Story 5
- [X] T023 [US5] Create materialized view migration — generate empty migration with `npx prisma migrate dev --create-only --name add_k1_materialized_views`, write raw SQL to create `mv_k1_partnership_year_summary` (GROUP BY partnership_id, tax_year, box_key with SUM(amount), COUNT), unique index for CONCURRENTLY refresh, initial REFRESH (see research.md §2 for exact SQL — update column names to use snake_case @@map names: k_document_id, box_key, is_superseded, etc.)
- [X] T024 [US5] Create K1MaterializedViewService in apps/api/src/app/k1-import/k1-materialized-view.service.ts — (a) `@OnEvent('k-document.changed')` handler calls `refreshAll()`, (b) `refreshAll()` executes `REFRESH MATERIALIZED VIEW CONCURRENTLY mv_k1_partnership_year_summary` via prisma.$executeRawUnsafe, (c) `getPartnershipYearSummary(partnershipId, taxYear)` queries the MV via prisma.$queryRaw<K1PartnershipYearSummary[]> (see research.md §2 for exact implementation)
- [X] T025 [US5] Emit 'k-document.changed' event from K1ImportService.confirm() in apps/api/src/app/k1-import/k1-import.service.ts — inject EventEmitter2 (already available via @nestjs/event-emitter, EventEmitterModule imported in app.module.ts), emit after successful K1LineItem creation with {kDocumentId, partnershipId} payload
- [X] T026 [US5] Register K1MaterializedViewService in K1ImportModule (apps/api/src/app/k1-import/k1-import.module.ts) and add API endpoint for partnership-year-summary in the K1 controller — GET /api/k1/summary/:partnershipId/:taxYear returning K1PartnershipYearSummary[]
**Checkpoint**: Materialized views auto-refresh on K-1 changes. Dashboard aggregation queries return correct totals via SQL in <50ms (SC-002).
---
## Phase 6: Polish & Cross-Cutting Concerns
**Purpose**: Finalize documentation, validate E2E pipeline, clean up dead code.
- [X] T027 [P] Update specs/006-k1-model-review/quickstart.md for clean-break workflow — remove references to dual-write, backfill, phased migration. Update migration order, key files table, testing commands, and architecture notes to reflect K1LineItem-only pipeline.
- [X] T028 Run end-to-end pipeline validation (SC-005) — start fresh: upload a K-1 PDF → extract → verify → confirm → query K1LineItem via SQL → query materialized view. Verify complete pipeline works. Document any issues found.
- [X] T029 [P] Final code cleanup — search for dead references: previousData, previousFilingStatus, verifiedData, CellMapping, CellAggregationRule, dual-write, backfill. Remove all dead code, unused imports, stale type references. Verify `npx nx build api` and `npx nx lint api` pass cleanly.

## Dependencies & Execution Order
### Phase Dependencies
```
Phase 1: Setup ──────────────────────► no dependencies
Phase 2: Foundational ───────────────► depends on Phase 1 (interfaces needed for type safety)
Phase 3: US2 (K1BoxDefinition) ──────► depends on Phase 2 (Prisma models + migration applied)
Phase 4: US1 (K1LineItem writes) ────► depends on Phase 3 (needs K1BoxDefinitionService.autoCreateIfMissing)
Phase 5: US5 (Dashboard MVs) ────────► depends on Phase 4 (needs K1LineItem data populated)
Phase 6: Polish ─────────────────────► depends on Phases 4 + 5
```
### User Story Dependencies
- **US2 (K1BoxDefinition)**: Can start after Phase 2. No dependencies on other stories. MUST complete before US1.
- **US1 (K1LineItem)**: Depends on US2 — `K1ImportService.confirm()` calls `K1BoxDefinitionService.autoCreateIfMissing()` (FR-017). K1LineItem FK targets K1BoxDefinition.
- **US5 (Dashboard)**: Depends on US1 — materialized views query K1LineItem data. No K1LineItems = empty views.
### Within Each User Story
- Module creation → Service implementation → Controller endpoints
- Schema models before service code (Phase 2 before Phase 3+)
- CellMapping removal (T019–T021) after new code is functional (T017–T018)
- Comparison test (T022) gates all commits (SC-006)
### Parallel Opportunities
- **Phase 1**: T002, T003, T004 can all run in parallel (different files)
- **Phase 3**: T012 (module) can run in parallel with T015 (data extraction)
- **Phase 4**: T019 (delete CellMapping) can run in parallel with T018 (aggregation rewrite) since they touch different files
- **Phase 6**: T027 and T029 can run in parallel (docs vs code cleanup)
---
## Parallel Example: Phase 1 Setup
```
# All three interface tasks can run simultaneously:
Task T002: Create k1-box-definition.interface.ts in libs/common/
Task T003: Create k1-line-item.interface.ts in libs/common/
Task T004: Export new interfaces from index.ts barrel
```
## Parallel Example: User Story 1
```
# After T017 (confirm rewrite) and T018 (aggregation rewrite) complete:
Task T019: Delete CellMapping module files
Task T020: Remove CellMapping from Prisma schema (after T019)
Task T021: Fix remaining compile errors (after T019 + T020)
```
---
## Implementation Strategy
### MVP First (User Story 2 + User Story 1)
1. Complete Phase 1: Setup (capture baseline, create interfaces)
2. Complete Phase 2: Foundational (schema + migration)
3. Complete Phase 3: User Story 2 — K1BoxDefinition module
4. Complete Phase 4: User Story 1 — K1LineItem writes + comparison test
5. **STOP and VALIDATE**: Run comparison test (T022). SC-006 gate must pass.
6. **First potential commit point** — normalized model functional, CellMapping removed
### Incremental Delivery
1. Setup + Foundational → Schema ready, interfaces available
2. Add US2 (K1BoxDefinition) → Reference table with FK enforcement → validateable independently
3. Add US1 (K1LineItem) → Full normalized pipeline → comparison test passes → **commit**
4. Add US5 (Dashboard) → Materialized views + API → deploy
5. Each story adds value without breaking previous stories
### Critical Constraint (SC-006)
> **No code changes are committed until the comparison test passes for at least one real K-1 PDF.**
The comparison test (T022) is the quality gate. T001 captures the baseline before any changes. T022 validates the new pipeline produces identical results. All implementation between T001 and T022 is uncommitted work-in-progress.

/**
* K1 Comparison Test — SC-006 Quality Gate
*
* Purpose: Validates that the new normalized K1LineItem pipeline produces
* correct output by:
*
* Part A (Pipeline Verification):
* - Takes EXTRACTED import sessions
* - Runs verify → confirm through the DB layer (simulating the service)
* - Asserts K1LineItems match extraction fields exactly
*
* Part B (Key Coverage Verification):
* - Maps baseline descriptive keys to IRS box numbers
* - Asserts all 23 baseline data keys have a corresponding K1BoxDefinition
*
* Usage: node --experimental-strip-types test/import/k1-comparison.test.mts
