# Data Model

> Primary entities and schema ownership model for DealDash data.

## Core Entity Groups

* identity: `users`
* delivery: `deals`, `influencers`, `contacts`
* execution: `tasks`, `reminders`, `notifications`
* collaboration: `team_*` tables, shares, user assignments
* media/links: `screenshots`, `short_links`

## Source of Truth

* canonical schema: `/server/db/schema.ts`
* migrations: `/migrations`

## Schema Change Rules

1. migration-first updates
2. update route validation and types in same change
3. run integration tests for impacted flows
4. update docs when entity or enum semantics change

## Drift Prevention

Do not rely on docs-only enums for automation decisions. Validate against schema definitions and route validation logic.
