Prisma Stock Model Implementation Spec

Goal

Initialize Prisma ORM with SQLite database and create a Stock model to persist manually added stock tickers in the AITrader analyze route.

Architecture

ORM: Prisma with SQLite datasource
Database file: prisma/dev.db
Model: Stock with id, ticker, optional notes, and timestamps
Integration: API routes for CRUD operations, integrated with analyze.tsx

Design Decisions

Stock Model Schema

model Stock {
  id        String   @id @default(cuid())
  ticker    String   @unique
  notes     String?
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
}

Rationale for notes field: Included for future extensibility (user notes on watched stocks). Nullable to avoid breaking changes.

Implementation Approach

Single migration (init) for all model fields
SQLite for development simplicity (matches plan)
Prisma client singleton pattern for React Router 7 compatibility

Files to Create/Modify

Task 1: Initialize Prisma

prisma/schema.prisma - Prisma schema with Stock model
prisma/dev.db - SQLite database (generated)

Success Criteria

npx prisma generate completes without errors
npx prisma migrate dev --name init creates prisma/dev.db
Git commit created with prisma/ changes

Dependencies to Install
