Fixes issue 3: the host-agent console showed OCR results but never real UI-tree data, because _ui_tree_nodes() checked for a get_ui_tree/ui_tree tool action that has never existed anywhere in the codebase. - storage/timeline.py: add a ui_tree_results field to TimelineRecord and Timeline.append(), mirroring the existing ocr_results field. - runtime/task.py: _append_timeline() now extracts scene.elements with source == "ui" into ui_tree_results (scene_builder.build_scene() already preserved these; they were just never persisted). - host_agent/web/app.py: _ui_tree_nodes() reads the new field directly instead of the dead tool-action check. New _overlay_payload() exposes each step's scene dimensions and fused element list for client-side rendering. - task_detail.html: adds a toggle to overlay OCR (orange) and UI-tree (blue) bounding boxes on the before-action screenshot, plus a visual marker for the actually executed action (tap circle, or an animated swipe path) using an SVG viewBox so no manual coordinate-scaling JS is needed. Legacy/incomplete records degrade to no overlay, never an error. Also corrects openspec/specs/runtime-task-evidence and host-agent-console-task-pages, which had encoded the same nonexistent-tool assumption, via the new host-agent-console-visual-evidence change. 600 tests passing; ruff/compileall/openspec validate all clean.
Device Agent Runtime
Device Agent Runtime is a device-agnostic runtime for LLM-driven automation. It gives agents a stable way to observe, decide, and act against real devices through a small set of domain models, driver contracts, tools, perception providers, and runtime orchestration.
iPhone automation through WebDriverAgent/Appium is the first driver, not the platform boundary. Future drivers can target Android, browsers, desktop environments, or other device surfaces without changing the runtime's core contracts.
Current Shape
core/: shared domain models and runtime errors.driver/: theDrivercontract, concrete driver adapters, and driver-type registry.device/: device lifecycle and active driver management.tools/: device capabilities exposed to Runtime and adapter layers.perception/: screen-to-Sceneperception behindPerceptionProvider.runtime/: planning and execution orchestration.api/: MCP and supporting integration adapters.storage/: timeline, task, and device configuration persistence.packages/cloud-platform/: cloud scheduling, device pooling, plugins, and the Python cloud SDK as thedevice-cloud-platformworkspace member.apps/cloud-api/: deployable authenticated Cloud Control Plane with PostgreSQL/SQLite persistence, scheduling, leases, and health endpoints.apps/device-host-agent/: outbound Host Agent that synchronizes configured devices and executes leased tasks through the existing Runtime/workflow.
Python Workspace
The repository uses a uv workspace with one committed lockfile. From the repository root, synchronize every Python member with:
uv sync --locked --all-packages
Run the complete local test suite in a workspace environment:
uv run --all-packages pytest -m "not integration"
Select one member when running package-specific commands:
uv run --package device-agent-runtime python -c "import runtime"
uv run --package device-cloud-platform python -c "import cloud"
uv run --package device-cloud-api device-cloud-api --help
uv run --package device-host-agent device-host-agent --help
uv build --package device-agent-runtime
uv build --package device-cloud-platform
Runtime is an in-process execution library, not a standalone HTTP service. The
Host Agent console at http://127.0.0.1:8765/tasks is the authenticated
operator view for the tasks that actually execute on that Host, including
per-step screenshots, OCR observations, and UI-tree results. The Cloud Console
remains the fleet-level view for dispatch status and Cloud-proxy planner history.
Project Direction
The durable roadmap is in docs/ROADMAP.md. The architecture invariants future changes must preserve are in docs/CONSTITUTION.md.
Operator Guides
- Cloud Control Plane deployment: run local SQLite or deployed PostgreSQL, configure credentials and Runtime AI planning, and perform orderly shutdown or rollback.
- macOS migration and real iPhone setup: install Xcode, Appium/XCUITest, sign WebDriverAgent, verify a real device, and run a connected Host Agent.
