## Symptom
After upgrading to Prisma 7: `prisma migrate dev` applies migrations but the client types are stale (new fields missing), the seed script never runs after `migrate dev`/`migrate reset`, `npm install` no longer produces a client, and scripts using `--skip-generate` / `--skip-seed` fail with an unknown-flag error. Wrong assumption: migrate runs `generate` and `seed` implicitly and postinstall generates the client.

## Cause
Prisma ORM 7.0.0 (2025-11-19) removed implicit commands: the postinstall hook no longer runs `prisma generate`; `prisma migrate dev`/`db push` no longer run `generate`; `migrate dev`/`migrate reset` no longer run the seed. The flags `--skip-generate` (migrate dev, db push) and `--skip-seed` (migrate dev) were removed. The `prisma` key in package.json (where `seed` used to live) was removed — the seed command now lives in `prisma.config.ts`. Also removed: `prisma introspect` (use `db pull`), `db execute --schema/--url`, `migrate diff --from-url/--to-url/--from-schema-datasource/--to-schema-datasource` (use `--from-config-datasource` / `--to-config-datasource`).

## Fix
Before (package.json):
```json
{
  "prisma": { "seed": "tsx prisma/seed.ts" },
  "scripts": { "db:migrate": "prisma migrate dev --skip-seed" }
}
```
After — `prisma.config.ts`:
```ts
import 'dotenv/config'
import { defineConfig, env } from 'prisma/config'
export default defineConfig({
  schema: 'prisma/schema.prisma',
  migrations: { path: 'prisma/migrations', seed: 'tsx prisma/seed.ts' },
  datasource: { url: env('DATABASE_URL') },
})
```
package.json scripts:
```json
{
  "scripts": {
    "postinstall": "prisma generate",
    "db:migrate": "prisma migrate dev && prisma generate",
    "db:seed": "prisma db seed"
  }
}
```
In CI/Docker builds, run `npx prisma generate` explicitly before `tsc`/`next build`.

## Verify
After `npm run db:migrate`, new model fields appear in the generated client types; `npx prisma db seed` runs the seed.
