Problem Statement

Issue #29 refactored the Total Cost of Ownership (TCO) feature to be document-driven via the ownership-costs feature. However, the legacy TCO fields were not removed from the vehicle forms, creating duplicate data entry points and user confusion.

Current State (Broken)

The following legacy fields still exist on VehicleForm (used by both New Vehicle and Edit Vehicle screens):

Field Location Status
insuranceCost VehicleForm Should be removed
insuranceInterval VehicleForm Should be removed
registrationCost VehicleForm Should be removed
registrationInterval VehicleForm Should be removed
tcoEnabled VehicleForm Should be removed
TCODisplay component VehicleDetailPage Should be removed

Problems:

  1. These fields are marked as required in the form schema, blocking vehicle creation/editing
  2. Insurance/registration costs should now be entered via the documents feature (linked to ownership-costs per #29)
  3. TCO display is being moved to a future reporting feature
  4. Users see duplicate cost entry points, creating confusion

Target State

  • Vehicle forms only collect vehicle attributes (VIN, year, make, model, purchase price, purchase date, etc.)
  • No recurring cost fields on vehicle forms
  • No TCO display on vehicle detail page (moved to future reporting feature)
  • Vehicle detail page shows associated documents only

Affected Areas

Frontend

  • frontend/src/features/vehicles/components/VehicleForm.tsx
    • Remove insuranceCost, insuranceInterval fields (lines ~844-920)
    • Remove registrationCost, registrationInterval fields (lines ~921-982)
    • Remove tcoEnabled checkbox
    • Update Zod schema to remove these fields
  • frontend/src/features/vehicles/types/vehicles.types.ts
    • Remove TCO field types from VehicleFormData
  • frontend/src/features/vehicles/pages/VehicleDetailPage.tsx
    • Remove TCODisplay component usage
    • Keep documents section display
  • frontend/src/features/onboarding/components/AddVehicleStep.tsx
    • Verify form changes propagate correctly

Backend

  • backend/src/features/vehicles/domain/vehicles.types.ts
    • Remove TCO fields from vehicle types (or mark as deprecated)
  • backend/src/features/vehicles/routes/vehicles.routes.ts
    • Update create/update schemas to not require TCO fields
  • backend/src/features/vehicles/domain/vehicles.service.ts
    • Remove any TCO calculation logic (or mark for future reporting feature)

Database

  • Consider migration to drop legacy columns (or defer to reporting feature work):
    • insurance_cost, insurance_interval
    • registration_cost, registration_interval
    • tco_enabled
  • Keep: purchase_price, purchase_date (valid vehicle attributes)

Acceptance Criteria

  • New Vehicle screen does not show insurance/registration cost fields
  • Edit Vehicle screen does not show insurance/registration cost fields
  • New Vehicle screen does not show TCO enabled checkbox
  • Edit Vehicle screen does not show TCO enabled checkbox
  • Vehicle Detail page does not show TCODisplay component
  • Vehicle Detail page still shows associated documents
  • Vehicle creation works without providing TCO fields
  • Vehicle editing works without TCO fields
  • Purchase price and purchase date fields remain on vehicle form
  • Mobile and desktop responsive design maintained
  • Existing vehicles with TCO data are not broken (graceful handling)

Out of Scope

  • TCO reporting feature (future work)
  • Database column removal (defer to reporting feature migration)
  • Ownership-costs feature changes (already working per #29)

Plan: Remove Legacy TCO Fields from Vehicle Forms

Phase: Planning | Agent: Planner | Status: AWAITING_REVIEW

Overview

Remove legacy TCO fields (insuranceCost, insuranceInterval, registrationCost, registrationInterval, tcoEnabled) from vehicle forms after the TCO refactor to document-driven ownership-costs feature (#29). Keep purchasePrice and purchaseDate as valid vehicle attributes. No backend or database changes.

Approach: Complete frontend cleanup - remove fields from forms, types, and delete unused components.

Planning Context

Decision Log

Decision Reasoning Chain
Complete cleanup over partial removal Legacy fields moved to ownership-costs feature in #29 -> keeping unused types creates confusion -> delete old code per CLAUDE.md guidelines
Keep purchasePrice/purchaseDate Issue #37 explicitly requires these fields remain -> valid vehicle attributes not related to recurring costs
Delete TCODisplay.tsx Component no longer used -> CLAUDE.md mandates 'delete old code when replacing it' -> future reporting feature can recreate if needed
No backend changes Issue #37 out of scope -> TCO endpoint needed for future reporting feature -> backend fields already optional
No new tests Field removal task -> existing tests validate form functionality -> default-conventions: 'do not test simple code'

Rejected Alternatives

Alternative Why Rejected
Keep form fields hidden Creates confusion, fields still in schema causing type mismatches with no user benefit
Deprecate with warnings Adds complexity, fields already moved to ownership-costs in #29, no gradual transition needed
Remove backend endpoint Future reporting feature needs TCO calculation (out of scope per issue)

Constraints & Assumptions

  • Backend TCO fields remain optional (no breaking changes)
  • Database columns preserved for future reporting feature
  • Mobile + desktop responsive design must be maintained

Known Risks

Risk Mitigation Anchor
Existing vehicles have TCO data Backend types preserve fields, graceful null handling Backend already handles optional fields
Form validation breaks TCO fields already optional in Zod schema VehicleForm.tsx:39-46 uses nullable().optional()

Milestones

Files:

  • frontend/src/features/vehicles/pages/VehicleDetailPage.tsx

  • Delete TCODisplay.tsx file entirely
  • Remove getTCO method from vehicles.api.ts (lines 93-99)
  • Remove TCOResponse from vehicles.api.ts import (line 6)

Acceptance Criteria:
