How to Update Entities

Prerequisites

Clone the tracker-radar-detector repo alongside this one and run npm install.
Update the tracker-radar-detector config.json so trackerRadarRepoPath points to your local clone of this repo (tracker-radar).

Steps

1. Edit `build-data/generated/entity_map.json`

Find the target entity and add the new domain to its properties array in alphabetical order.

2. Run `npm run apply-entity-changes` in the tracker-radar-detector repo

This propagates changes to all dependent files:

File	What changes
`build-data/generated/entity_map.json`	The source of truth you edited
`build-data/generated/domain_map.json`	Reverse mapping — one entry per domain with `entityName`, `aliases`, `displayName`
`entities/<Entity Name>.json`	The entity file gets the domain added to its `properties` array

3. Verify

entity_map.json — domain in the entity's properties, alphabetically sorted
domain_map.json — new key for the domain with correct entityName, aliases, displayName
entities/<Entity Name>.json — domain in properties, alphabetically sorted
All three files are valid JSON
Run npm test to validate schemas
