### Known Issues

- Map-MCP 3D view initialization can fail intermittently (error: "3D 视图未初始化")
- Semantic search similarity scores vary by feature prevalence in region (e.g., "dunes" scored 0.27, "craters" scored 0.45)
- Browser connection issues can occur intermittently (timeout errors, 15s timeout encountered on 2026-03-17 at 17:30)
- Some semantic descriptions in Argyre Planitia results showed anomalies (orange geometric placeholders instead of geological descriptions)
- **Map-MCP viewport bbox coordinates frequently return global bounds (-180 to 180) instead of actual view** (confirmed multiple times on 2026-03-17, including 19:44)
- Argyre Planitia bbox (-52°, -58°) to (-22°, -38°) drawn and queried 5+ times with consistent 259 results
- Map altitude parameter is not always preserved during flights (actual altitude may differ from requested)

## Important Notes

- Semantic search similarity scores: higher is better (1.0 = perfect match), but scores vary by feature abundance
- Visual descriptions from semantic search include detailed geological analysis (features, landforms, scientific significance)
- Map altitudes used: 100km (detailed view), 4000+km (regional overview), 10,000-23,000km (global/regional)
- Map-MCP viewport bbox coordinates frequently return global bounds (-180 to 180) instead of actual view - persistent issue
- Argyre Planitia data is primarily from June 2022 Tianwen-1 observations
- Some semantic descriptions may be incomplete or anomalous (placeholders)
- Primary Argyre Planitia bbox for repeated queries: (-52°, -58°) to (-22°, -38°), returns 259 Tianwen-1 images + 48 Mars CTX images
- Browser timeout issues can interrupt map operations (15s timeout)
- North Polar Cap composition: water ice and CO2 ice, ~1,000 km diameter
- South Polar Cap: ~350 km diameter permanent, up to 1,000 km seasonal expansion
- Highest recorded altitude: 26,673 km at global view (2026-03-17 19:44)
- Assistant is a Mars Digital Assistant enabling natural language interaction for all platform operations
