# FIX-157 — Architect

## Fix
Reporting sub-items (Dashboard, Ventas, Productos) appeared as separate top-level nav items with leading spaces. They should be nested under /reporting.

## Solution
- Added `parentHref` field to `NavItem` interface
- Added `topNavItems()` and `subNavItems()` helpers
- Sidebar renders sub-items indented under their parent
- `visibleNavItems()` replaced with `topNavItems()` for top-level items
