- add output column to ScenarioRunStepEntity; exec step return value is JSON-serialised and stored - expose helpers.getStepOutput(order) in exec code; negative order is relative to current step - add get_scenario_run, wait_for_scenario_run, export_scenario, import_scenario MCP tools - move Architecture, Key descriptors, MCP tools, Scenario, Development docs to docs/ - delete CONTRIBUTING.md (replaced by docs/development.md)

data/sessions.db
- McpService — registers every MCP tool and delegates to domain services.
- AuthService — drives a Playwright browser to log in via a key descriptor; saves cookies + localStorage as a
Session. - SessionService — stores and retrieves saved browser sessions.
- EnvironmentService — stores named environments (URL maps) used by auth and scenarios.
- BrowserService — ad-hoc, stateless
open_url/exec_codeoperations outside the scenario scheduler. - CodeExecutorService — compiles and runs user-supplied Playwright JS inside a sandboxed
asyncfunction withpage,context, andhelpersin scope. - ScenarioService — CRUD for scenarios, steps, runs, and run logs; import/export.
- ScenarioSchedulerService — polls for pending step runs every second and executes them. All steps in the same run share one browser instance (see scenario.md).
