# Implementation Plan: Inventory Dependencies Graph

**Date**: 2026-01-07  
**Spec**: `specs/042-inventory-dependencies-graph/spec.md`

## Summary

Add dependency edge model, extraction logic, and UI views to explain relationships between inventory items and prerequisite/foundation objects.

## Dependencies

- Inventory items and stable identifiers (Spec 040)
- Inventory UI detail pages (Spec 041) or equivalent navigation

## Deliverables

- Relationship taxonomy
- Persisted dependency edges
- Query and rendering in UI

## Risks

- Heterogeneous reference shapes across policy types
- Edge explosion for large tenants
