# Quickstart — Inventory Dependencies Graph (042)

## Prerequisites

- Run the app via Sail.
- Ensure you have at least one tenant and inventory items.

## Viewing Dependencies

1. Navigate to **Inventory** → select an Inventory Item.
2. In the **Dependencies** section use the querystring-backed filters:

- `direction`: `all` (default) | `inbound` | `outbound`
- `relationship_type`: `all` (default) | `assigned_to` | `scoped_by` | `targets` | `depends_on`

Example URLs:
- `...?direction=outbound&relationship_type=scoped_by`

## Running the Targeted Tests

- UI smoke tests:
  - `./vendor/bin/sail artisan test tests/Feature/InventoryItemDependenciesTest.php`

## MVP Notes

- Limit-only, no pagination.
- Shows <=50 edges per direction (<=100 total when showing both directions).
- Unknown/unsupported reference shapes are warning-only and should be visible via `InventorySyncRun.error_context.warnings[]`.

## Manual Performance Check (<2s)

1. Open an Inventory Item with ~50 inbound and/or ~50 outbound edges.
2. Use browser devtools Network tab to confirm the page request completes quickly.
3. Toggle `direction` and `relationship_type` filters and confirm responses remain fast.
