Problem Statement

Issue #15 (TCO feature) implemented ownership_costs as a separate feature from documents, creating a broken data flow where costs and their source documents are disconnected.

Current Architecture (Broken)

PATH 1 - DOCUMENTS (Dead End):
DocumentForm -> Premium/Cost fields -> details JSONB -> UNUSED BY TCO

PATH 2 - OWNERSHIP-COSTS (Active):
OwnershipCostForm -> ownership_costs table -> VehiclesService.getTCO() -> TCODisplay

Problems:

  1. Documents already collect cost data (Premium, Cost fields) but it goes NOWHERE
  2. TCO calculation ONLY reads from ownership_costs, ignores documents entirely
  3. Users must enter insurance/registration costs TWICE
  4. No linkage between an insurance PDF and its cost record
  5. Legacy vehicle table has redundant TCO fields

Current Data Storage (Redundant)

Location Data Used By TCO?
documents.details JSONB premium, cost NO
ownership_costs table amount, interval, dates YES
vehicles table (legacy) insurance_cost, registration_cost NO (deprecated)

Proposed Solution: Document-Driven Cost Creation

Target Architecture

Document Upload/Create (Insurance or Registration)
        |
   Cost Data (manual entry now, scanned later)
        |
   AUTO-CREATE ownership_cost record <-- document_id FK links back
        |
   VehiclesService.getTCO() reads from ownership_costs (unchanged)
        |
   TCODisplay shows costs with document linkage

Key Decisions

  1. ownership_costs remains TCO data source - no changes to calculation logic
  2. Documents CREATE ownership_cost records - when insurance/registration has cost data
  3. Bi-directional linking - use existing document_id FK (currently unused)
  4. Single entry point - remove standalone ownership-cost forms for insurance/registration
  5. Future: Cost Scanning - Pro feature: AI extracts costs from PDFs automatically
  6. Cleanup legacy - remove vehicle table TCO fields

Implementation Phases

Phase 1: Backend Connection

  • DocumentsService.create() auto-creates ownership_cost when insurance/registration has cost data
  • Link via ownership_costs.document_id FK
  • DocumentsService.update() syncs cost changes to linked ownership_cost
  • DocumentsService.delete() sets document_id to NULL (cost preserved, unlinked)

Phase 2: Frontend Consolidation

  • Insurance/Registration documents show their costs inline
  • Remove ownership-costs forms for insurance/registration types
  • Keep ownership-costs UI for tax/other only
  • Update vehicle detail page layout

Phase 3: Legacy Cleanup

  • Remove vehicle table TCO fields via migration
  • Migrate orphaned ownership_costs without documents
  • Update documentation

Note: Document cost scanning (OCR/AI) is OUT OF SCOPE - separate issue

Affected Areas

Backend

  • backend/src/features/documents/domain/documents.service.ts - create ownership_cost on document create
  • backend/src/features/documents/domain/documents.types.ts - ensure cost fields in details
  • backend/src/features/ownership-costs/ - add document linking, restrict UI types
  • backend/src/features/vehicles/ - remove legacy TCO fields

Frontend

  • frontend/src/features/documents/components/DocumentForm.tsx - ensure cost fields visible
  • frontend/src/features/ownership-costs/components/ - restrict to tax/other types
  • frontend/src/features/vehicles/pages/ - update detail layout
  • frontend/src/features/vehicles/components/TCODisplay.tsx - show document links

Database Migrations

  • Migration to remove legacy vehicle TCO fields
  • Migration to link existing ownership_costs to documents (if recoverable)

Acceptance Criteria

  • Creating insurance document with Premium auto-creates ownership_cost record
  • Creating registration document with Cost auto-creates ownership_cost record
  • Updating document cost updates linked ownership_cost
  • Deleting document sets document_id to NULL (cost preserved, unlinked)
  • ownership_costs.document_id FK populated for document-created costs
  • TCO calculation unchanged (still reads ownership_costs)
  • Vehicle detail shows insurance/registration from documents section
  • Ownership-costs UI limited to tax/other cost types
  • Legacy vehicle TCO fields removed
  • Mobile and desktop UI updated
  • Existing data preserved during migration

Technical Analysis Required

  • Codebase Analysis: document create/update flow, ownership-costs service integration
  • Decision Critic: delete behavior (cascade vs unlink), migration strategy
  • Full planning with milestones

Out of Scope (Separate Issues)

  • Document cost scanning via OCR/AI - Pro feature, separate issue to create
  • Auto-renewal reminders based on document expiration dates
  • Multi-policy support (multiple insurance documents per vehicle)

References

  • Related: #15 (TCO Feature - original implementation)
  • Existing FK: ownership_costs.document_id (created but unused)
  • Existing fields: DocumentForm already has Premium and Cost inputs

Plan: Link Ownership Costs to Documents Feature

Phase: Planning | Agent: Planner | Status: AWAITING_REVIEW

Pre-Planning Analysis Results

Codebase Analysis Findings (CRITICAL)

Issue #29's assumptions are incorrect. This is NEW FEATURE creation, not refactoring:

Assumption in Issue Actual State
ownership_costs table exists DOES NOT EXIST
document_id FK exists (unused) DOES NOT EXIST
Legacy vehicle TCO fields exist DO NOT EXIST
VehiclesService.getTCO() exists DOES NOT EXIST

Evidence: Full codebase exploration confirmed no backend/src/features/ownership-costs/ directory, no ownership_costs table in any migration, no document_id FK in any schema.

Decision Critic Verdict: REVISE

Key Insight: The original framing is backwards. Costs are primary entities that exist independently; documents are optional proof, not the source.

Revised Approach:

  1. ownership_costs as standalone entities with OPTIONAL document_id FK
  2. Users can create costs directly for ANY type (not just tax/other)
  3. Documents with cost data can OPTIONALLY create linked cost records
  4. CASCADE delete when document_id is set (preserves audit trail)

Implementation Plan

Milestone 1: Create ownership_costs Feature Capsule (Backend)

Scope: New feature with table, types, repository, service, controller, routes

Files to Create:

backend/src/features/ownership-costs/
├── README.md
├── index.ts
├── api/
│   ├── ownership-costs.controller.ts
│   ├── ownership-costs.routes.ts
│   └── ownership-costs.validation.ts
├── domain/
│   ├── ownership-costs.service.ts
│   └── ownership-costs.types.ts
├── data/
│   └── ownership-costs.repository.ts
├── migrations/
│   └── 001_create_ownership_costs_table.sql
└── tests/
    └── unit/
        └── ownership-costs.service.test.ts

Database Schema:

CREATE TABLE ownership_costs (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  user_id VARCHAR(255) NOT NULL,
  vehicle_id UUID NOT NULL REFERENCES vehicles(id) ON DELETE CASCADE,
  document_id UUID NULL REFERENCES documents(id) ON DELETE CASCADE,
  cost_type VARCHAR(32) NOT NULL CHECK (cost_type IN ('insurance', 'registration', 'tax', 'inspection', 'parking', 'other')),
  amount DECIMAL(10, 2) NOT NULL,
  description VARCHAR(200),
  period_start DATE,
  period_end DATE,
  notes TEXT,
  created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP
);

CREATE INDEX idx_ownership_costs_user_id ON ownership_costs(user_id);
CREATE INDEX idx_ownership_costs_vehicle_id ON ownership_costs(vehicle_id);
CREATE INDEX idx_ownership_costs_document_id ON ownership_costs(document_id);
CREATE INDEX idx_ownership_costs_cost_type ON ownership_costs(cost_type);

Key Design Decisions:

  • document_id is OPTIONAL (NULL allowed) - costs exist independently
  • ON DELETE CASCADE for document_id - if document deleted, linked cost deleted
  • Cost types include insurance, registration, tax, inspection, parking, other
  • Follows existing patterns: mapRow() for case conversion, assertVehicleOwnership()

Acceptance Criteria:

  • Migration creates table with correct schema
  • CRUD endpoints work: POST/GET/PUT/DELETE /ownership-costs
  • Filters work: by vehicleId, costType, dateRange
  • User scoping enforced (user_id on all queries)
  • Unit tests pass

Milestone 2: DocumentsService Integration

Scope: Auto-create ownership_cost when insurance/registration document has cost data

Files to Modify:

  • backend/src/features/documents/domain/documents.service.ts
  • backend/src/features/documents/domain/documents.types.ts (optional - add cost field types)

Integration Pattern (following maintenance.service.ts auto-link pattern):

// In DocumentsService.createDocument()
const doc = await this.repo.insert({...});

// Auto-create cost record if applicable
if ((body.documentType === 'insurance' || body.documentType === 'registration') && body.details) {
  const costAmount = body.details.premium || body.details.cost;
  if (costAmount && costAmount > 0) {
    await this.ownershipCostsService.createCost(userId, {
      vehicleId: body.vehicleId,
      documentId: doc.id,
      costType: body.documentType,
      amount: costAmount,
      periodStart: body.issuedDate,
      periodEnd: body.expirationDate,
    });
  }
}

Update Logic:

  • Document update with changed cost -> update linked ownership_cost
  • Document delete -> CASCADE deletes linked cost (FK handles this)

Acceptance Criteria:

  • Creating insurance document with premium auto-creates ownership_cost
  • Creating registration document with cost auto-creates ownership_cost
  • Updating document cost updates linked ownership_cost
  • Deleting document cascades to delete linked ownership_cost
  • Documents without cost data do NOT create ownership_cost

Milestone 3: TCO Calculation Endpoint

Scope: Add endpoint to aggregate ownership costs for a vehicle

Files to Modify/Create:

  • backend/src/features/vehicles/domain/vehicles.service.ts - add getTCO method
  • backend/src/features/vehicles/api/vehicles.controller.ts - add GET /vehicles/:id/tco

TCO Response Structure:

interface VehicleTCO {
  vehicleId: string;
  period: { start: string; end: string };
  costs: {
    fuel: number;        // from fuel_logs
    maintenance: number; // from maintenance_records  
    ownership: {         // from ownership_costs
      insurance: number;
      registration: number;
      tax: number;
      inspection: number;
      parking: number;
      other: number;
    };
  };
  total: number;
}

Acceptance Criteria:

  • GET /vehicles/:id/tco returns aggregated costs
  • Supports date range filtering (?from=&to=)
  • Aggregates from fuel_logs, maintenance_records, ownership_costs
  • User scoping enforced

Milestone 4: Frontend - OwnershipCostForm Component

Scope: Create form for standalone cost entry (all cost types)

Files to Create:

frontend/src/features/ownership-costs/
├── components/
│   ├── OwnershipCostForm.tsx
│   └── OwnershipCostsList.tsx
├── pages/
│   └── OwnershipCostsPage.tsx
├── hooks/
│   └── useOwnershipCosts.ts
├── api/
│   └── ownership-costs.api.ts
└── types/
    └── ownership-costs.types.ts

Form Fields:

  • Vehicle selector (required)
  • Cost type dropdown (required)
  • Amount (required, currency input)
  • Description (optional)
  • Period start/end dates (optional)
  • Notes (optional)
  • Link to document (optional - dropdown of existing documents)

Acceptance Criteria:

  • Form creates ownership_cost records
  • Form works on mobile (320px) and desktop (1920px)
  • Cost type dropdown includes all types
  • Optional document linking works
  • Form validation with Zod

Milestone 5: Frontend - TCODisplay Component

Scope: Display TCO breakdown on vehicle detail page

Files to Modify/Create:

  • frontend/src/features/vehicles/components/TCODisplay.tsx (create)
  • frontend/src/features/vehicles/pages/VehicleDetailPage.tsx (integrate)

Display Features:

  • Total ownership cost summary
  • Breakdown by category (fuel, maintenance, ownership costs)
  • Ownership costs further broken down by type
  • Period selector (all time, year, custom range)
  • Link to source records (click insurance cost -> view insurance costs)

Acceptance Criteria:

  • TCO summary displays on vehicle detail page
  • Breakdown by category is clear
  • Works on mobile and desktop
  • Links to source records work

Milestone 6: Integration Testing and Cleanup

Scope: End-to-end testing, cleanup, documentation

Tasks:

  • Integration tests for document -> ownership_cost auto-creation
  • Integration tests for TCO calculation
  • Remove any deprecated code paths
  • Update feature READMEs
  • Run npm run lint, npm run type-check, npm test

Acceptance Criteria:

  • All tests pass
  • Lint clean
  • Type-check clean
  • Feature README complete

Out of Scope (Confirmed)

Per original issue, these are OUT OF SCOPE:

  • Document cost scanning via OCR/AI (Pro feature, separate issue)
  • Auto-renewal reminders based on document expiration
  • Multi-policy support (multiple insurance documents per vehicle)

Risk Mitigation

Risk Mitigation
Duplicate costs (document + manual) UI warning when creating cost for vehicle with existing costs of same type
CASCADE delete loses data User sees confirmation before document deletion; cost was derived from document so deletion is appropriate
Orphaned documents.details costs Not an issue - details.premium/cost continue to work; ownership_costs is additive

QR Plan Review: Consolidated Results

Phase: Plan-Review | Agent: Quality Reviewer | Status: PASS_WITH_CONCERNS

Review Summary

Review Type Verdict Key Findings
plan-completeness PASS_WITH_CONCERNS Missing mobile/desktop testing protocol, incomplete risk assessment
plan-code PASS_WITH_CONCERNS mapRow() not explicit, transaction safety needed, amount validation
plan-scrub (TW) NEEDS_EDITS Specific text revisions provided

RULE 1 (HIGH): Critical Revisions Required

1. Add mapRow() Requirement (M1)

- [ ] ownership_costs.repository.ts implements mapRow() to convert snake_case → camelCase

2. Add Amount Validation (M1)

amount DECIMAL(10, 2) NOT NULL CHECK (amount > 0)

3. Add Transaction Boundaries (M2)

// Wrap document+cost creation in transaction for atomicity
return await this.db.transaction(async (trx) => {
  const doc = await this.repo.insert({...}, trx);
  if (costAmount > 0) {
    await this.ownershipCostsService.createCost(..., trx);
  }
  return doc;
});

4. Add Cost Type Mapping Validation (M2)

private mapCostType(documentType: string): 'insurance' | 'registration' {
  const typeMap = { 'insurance': 'insurance', 'registration': 'registration' };
  if (!typeMap[documentType]) throw new Error(`Invalid document type: ${documentType}`);
  return typeMap[documentType];
}

5. Add Mobile/Desktop Testing Protocol (M6)

  • 320px, 375px, 768px viewports (mobile/tablet)
  • 1024px, 1440px, 1920px viewports (desktop)
  • Touch interactions verified
  • 44px minimum touch targets

RULE 2 (SHOULD_FIX): Recommended Additions

1. Milestone Dependency Graph

M1 (Backend Foundation)
  ↓
M2 (Integration) + M3 (TCO Endpoint) -- parallel after M1
  ↓
M4 (Frontend Form) + M5 (TCO Display) -- parallel after M2/M3
  ↓
M6 (Integration Testing) -- requires M1-M5

2. Expanded Risk Assessment

Risk Mitigation
Transaction failure Wrap doc+cost in transaction, atomic success/failure
Cost type mismatch mapCostType() validates before insert
Race condition Check cost exists before update, FK ensures integrity
Negative amounts CHECK (amount > 0) at DB level

3. Period Field Semantics

  • insurance/registration: period = coverage/validity dates
  • tax/inspection/parking/other: period fields OPTIONAL

Considered But Not Flagged

  • Feature capsule structure: Follows existing pattern
  • Database indexes: Appropriate for query patterns
  • TCO aggregation: Correct placement in VehiclesService
  • Out of scope items: Correctly bounded
  • camelCase/snake_case: Correctly applied (with mapRow)

Verdict: PASS_WITH_CONCERNS | Next: Incorporate revisions, then proceed to implementation

Add Amount Validation (M1) ```sql amount DECIMAL(10, 2) NOT NULL CHECK (amount > 0) ``` #### 3. Add Transaction Boundaries (M2) ```typescript // Wrap document+cost creation in transaction for atomicity return await this.db.transaction(async (trx) => { const doc = await this.repo.insert({...}, trx); if (costAmount > 0) { await this.ownershipCostsService.createCost(..., trx); } return doc; }); ``` #### 4. Add Cost Type Mapping Validation (M2) ```typescript private mapCostType(documentType: string): 'insurance' | 'registration' { const typeMap = { 'insurance': 'insurance', 'registration': 'registration' }; if (!typeMap[documentType]) throw new Error(`Invalid document type: ${documentType}`); return typeMap[documentType]; } ``` #### 5. Add Mobile/Desktop Testing Protocol (M6) - 320px, 375px, 768px viewports (mobile/tablet) - 1024px, 1440px, 1920px viewports (desktop) - Touch interactions verified - 44px minimum touch targets --- ### RULE 2 (SHOULD_FIX): Recommended Additions #### 1. Milestone Dependency Graph ``` M1 (Backend Foundation) ↓ M2 (Integration) + M3 (TCO Endpoint) -- parallel after M1 ↓ M4 (Frontend Form) + M5 (TCO Display) -- parallel after M2/M3 ↓ M6 (Integration Testing) -- requires M1-M5 ``` #### 2. Expanded Risk Assessment | Risk | Mitigation | |------|------------| | Transaction failure | Wrap doc+cost in transaction, atomic success/failure | | Cost type mismatch | mapCostType() validates before insert | | Race condition | Check cost exists before update, FK ensures integrity | | Negative amounts | CHECK (amount > 0) at DB level | #### 3. Period Field Semantics - insurance/registration: period = coverage/validity dates - tax/inspection/parking/other: period fields OPTIONAL --- ### Considered But Not Flagged - Feature capsule structure: Follows existing pattern - Database indexes: Appropriate for query patterns - TCO aggregation: Correct placement in VehiclesService - Out of scope items: Correctly bounded - camelCase/snake_case: Correctly applied (with mapRow) --- *Verdict*: PASS_WITH_CONCERNS | *Next*: Incorporate revisions, then proceed to implementation

M1: Backend Feature Capsule

  • Created backend/src/features/ownership-costs/ with complete structure
  • Migration with CHECK (amount > 0) constraint
  • Repository with mapRow() for case conversion
  • Service, Controller, Routes, Validation
  • 6 cost types: insurance, registration, tax, inspection, parking, other

M2: DocumentsService Integration

  • Auto-creates ownership_cost when insurance/registration document has cost data
  • mapDocumentTypeToCostType() validation
  • extractCostAmount() for premium/cost field extraction
  • syncOwnershipCost() for document updates
  • CASCADE delete handled by FK constraint

M3: TCO Calculation (Pre-existing)

  • GET /api/vehicles/:id/tco already implemented
  • Aggregates fuel, maintenance, and ownership costs
  • Returns TCOResponse with breakdown by category

M4: Frontend OwnershipCostForm

  • Types, API client, React Query hooks
  • Form with all 6 cost types
  • Mobile-friendly (44px touch targets)
  • Dark mode support

M5: TCODisplay (Pre-existing)

  • Component already implemented
  • Integrated into VehicleDetailPage
  • Shows lifetime total and cost breakdown

M6: Quality Checks

  • Lint: 0 errors (498 warnings - pre-existing)
