- ✓Health score (0–1000) with bands (Healthy, At Risk, Poor)
- ✓Aged inventory detection (units >180d, >365d) with removal recommendations
- ✓LTSF (Long-Term Storage Fee) projection for the next billing cycle
- ✓Stranded inventory alerts with one-click removal order generation
- ✓Per-FC (fulfillment center) and per-region visibility

Real-time sync from Amazon API
Green bolt = Live sync active
Indicator shows "last synced 5m ago". Data is always within 1 hour of Amazon's actual state.
How it works: Amazon Fulfillment Inbound API provides inventory snapshots every 15–60 minutes. Zobrx polls on a schedule and listens for real-time webhook events.
Refresh cadence: Primary data refresh every hour; webhook events trigger immediate updates.
Latency: Most data within 15 min of Amazon's source. Some metrics (aged inventory, LTSF projection) recalculate daily.
