# Resource Limit Test Scenarios

## RL-01: ZIP File Size Limit (50 MB)

**Trigger**: Create route with enough tiles to approach 50 MB ZIP limit
**Observable**: ZIP file size
**Pass criterion**: ZIP file ≤ 50 MB; tiles included up to limit; no crash on boundary

## RL-02: Queue Capacity (1000)

**Trigger**: Submit 1000 region requests
**Observable**: Queue accepts all 1000
**Pass criterion**: All 1000 requests accepted and queued; no rejection until capacity reached

## RL-03: Concurrent Download Semaphore (4)

**Trigger**: Process region with many tiles
**Observable**: Concurrent outbound HTTP connections
**Pass criterion**: Never exceeds 4 simultaneous tile downloads (configurable via ProcessingConfig.MaxConcurrentDownloads)

## RL-04: Concurrent Region Processing (20)

**Trigger**: Queue 25 region requests
**Observable**: Processing parallelism
**Pass criterion**: At most 20 regions processing simultaneously (configurable via ProcessingConfig.MaxConcurrentRegions); remaining wait in queue
