Installation

composer require cboxdk/laravel-nexus

The service provider auto-registers and binds:

• NexusThresholdSource → the dataset-backed source (reads us-tax-data's by-section/nexus.json from the public mirror; see configuration).
• SalesLedger, PhysicalNexus, NexusRegistrations → empty defaults (deny-by-default). These are your data — rebind them (see data seams).
• NexusEngine → the shipped DefaultNexusEngine.

Publish the config if you want to change the dataset location or the approaching band:

php artisan vendor:publish --tag=nexus-config
