Architecture

Clean Architecture (Android)

Clear and decoupled pipeline:
collecting → filtering → locating → grounding

• Strict separation of concerns across components
• Each stage can evolve or be replaced independently

---

Element Perception

• Dedicated and isolated Android UI element collector
• Filtering strategies externalized and configurable
• Locator builder supporting multiple strategy types
• Single entry point for locator generation and access

---

Grounding & Annotation

• Improved grounding using structured JSON items
• Better handling of small UI elements
• Cross-platform support (Linux / Windows)
• Grounding logic consolidated under a grounding/ directory

---

Configuration

• Added configuration variables related to SoM
• Screen size fallback handling
• Prompts externalized into a dedicated directory
• Mobile connector adapted to support these changes
