Tasks: Inventory Dependencies Graph

Schema & Data Model

• T001 Define relationship taxonomy (enum or config) with display labels, directionality, descriptions
• T002 Create inventory_links migration with unique constraint + indexes
• T003 Create InventoryLink model + factory

Extraction Pipeline

• T004 Implement DependencyExtractionService (normalize references, resolve targets, create edges)
• T005 Add reference parsers for assigned_to, scoped_by, targets, depends_on
• T006 Integrate extraction into InventorySyncService (post-item-creation hook)
• T007 Implement 50-edge-per-direction limit with priority sorting

Query Services

• T008 Implement DependencyQueryService::getOutboundEdges(item, type?, limit=50)
• T009 Implement DependencyQueryService::getInboundEdges(item, type?, limit=50)
• T010 Ensure tenant-scoping enforced at query builder level

UI Components

• T011 Add "Dependencies" section to InventoryItemResource ViewInventoryItem page
• T012 Implement direction filter (single-select: all/inbound/outbound, default: all)
• T013 Create Blade view dependency-edges.blade.php (zero-state, missing badge, tooltip)
• T014 Add relationship-type grouping/collapsible sections

Tests

• T015 Unit: DependencyExtractionServiceTest (determinism, unique key, unsupported refs)
• T016 Unit: InventoryLinkTest (unique constraint, tenant scoping)
• T017 Feature: extraction creates expected edges + handles missing targets
• T018 Feature: extraction respects 50-edge limit
• T019 Feature: DependencyQueryService filters by tenant + direction
• T020 UI Smoke: dependencies section renders + filter works + zero-state shown
• T021 Security: tenant isolation (cannot see other tenant edges)

Finalization

• T022 Run full test suite (php artisan test)
• T023 Run Pint (vendor/bin/pint)
• T024 Update checklist items in checklists/pr-gate.md
