+## Purpose
+
+Define how the Python repository is structured as a uv workspace, including the shared lockfile, one-way dependency direction between the Runtime and cloud platform packages, import-path and behavior compatibility during the packaging migration, independent buildability of workspace members, and the boundary that keeps the frontend JavaScript project outside the Python workspace.
+
+## Requirements
+
+### Requirement: Repository uses a uv workspace with a shared lockfile
+The repository SHALL define a uv workspace containing the root `device-agent-runtime` project and the extracted `device-cloud-platform` project, and SHALL commit one generated `uv.lock` that resolves all workspace members.
+
+#### Scenario: Clean workspace synchronization
+- **WHEN** a developer synchronizes the repository from a clean checkout using uv
+- **THEN** uv installs the workspace members and their locked dependencies without requiring manual editable-install commands
+
+#### Scenario: Lockfile consistency check
+- **WHEN** CI validates dependency metadata without updating dependencies
+- **THEN** the committed lockfile is accepted as current for every workspace member
+
+### Requirement: Cloud packaging has an explicit one-way Runtime dependency
+The `device-cloud-platform` project SHALL declare `device-agent-runtime` as a uv workspace dependency, and the `device-agent-runtime` project MUST NOT depend on `device-cloud-platform` or import the `cloud` package.
+
+#### Scenario: Cloud modules consume Runtime contracts
+- **WHEN** the cloud platform is installed through the workspace
+- **THEN** its imports of existing Runtime, workflow, storage, and driver contracts resolve through the declared Runtime workspace dependency
+
+#### Scenario: Runtime remains cloud-independent
+- **WHEN** dependency-direction tests inspect Runtime-owned source packages
+- **THEN** no Runtime-owned package imports `cloud` or requires the cloud distribution to execute existing local capabilities
+
+### Requirement: Existing cloud import paths and behavior remain compatible
+The packaging migration SHALL preserve the existing `cloud.*` Python import paths and SHALL NOT change REST, MCP, scheduling, dispatch, persistence, or SDK behavior.
+
+#### Scenario: Existing cloud tests run after extraction
+- **WHEN** the existing cloud test suite runs from the workspace root after the package is moved
+- **THEN** the tests import the same `cloud.*` modules and retain their pre-migration behavior
+
+#### Scenario: Local Runtime runs without cloud application members
+- **WHEN** a developer starts or tests the root Runtime project without starting a cloud application
+- **THEN** existing Runtime entry points and local device behavior remain available
+
+### Requirement: Workspace members are independently buildable and selectable
+Each Python workspace member SHALL contain valid build metadata, SHALL produce an installable distribution, and SHALL support member-scoped uv commands while root-level tests remain supported.
+
+#### Scenario: Build all distributions
+- **WHEN** CI builds the Runtime and cloud platform workspace members
+- **THEN** each build produces a wheel whose declared packages can be imported in an isolated environment
+
+#### Scenario: Run a member-scoped command
+- **WHEN** a developer selects a workspace member with uv's package selection option
+- **THEN** the command executes with that member's declared dependencies and workspace sources
+
+### Requirement: Frontend package management remains separate
+The Vue/Vite `console` project SHALL remain managed by its existing JavaScript package manager and SHALL NOT become a Python uv workspace member.
+
+#### Scenario: Synchronize Python workspace
+- **WHEN** a developer runs uv synchronization at the repository root
+- **THEN** uv does not install or modify the console's JavaScript dependencies
