Replaces the stub Planner's fixed describe_screen/[] behavior with a real decision-maker: AIPlanner uses native tool/function calling (Anthropic or OpenAI, pluggable via AI_PLANNER_PROVIDER) to select exactly one grounded action per turn, with an explicit finish_task(success, reason) tool for completion/failure instead of an ambiguous "no tool call" signal. Default disabled (AI_PLANNER_ENABLED=false) and additive; TaskRunner falls back to the existing stub Planner unchanged when disabled. Amends CONSTITUTION.md's Perception Boundary with one narrow exception: only the AI Planner may receive the current step's raw screenshot bytes alongside Scene, for vision-grounded coordinate grounding. Also fixes a latent gap in TaskRunner.run(): observe/plan exceptions are now caught per iteration and turned into a failed task with a failure_reason, instead of propagating uncaught. openspec change: ai-planner-runtime.

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 API layers.perception/: screen-to-Sceneperception behindPerceptionProvider.runtime/: planning and execution orchestration.api/: REST/MCP transport adapters.storage/: timeline, task, and device configuration persistence.
Project Direction
The durable roadmap is in docs/ROADMAP.md. The architecture invariants future changes must preserve are in docs/CONSTITUTION.md.
