Internal SmartGift build of a Claude Code monitoring dashboard. Lanes: a durable unit of parallel agent work, one per working directory, tracked across session restarts. Managed lanes are git worktrees the dashboard provisions and can reset or remove behind a three-check destroy guard and a counted preflight; adopted lanes are directories you already own and are never destroyable. Pipelines: a lane moves through pipeline stages. A stage the agent declares with evidence renders green; a stage inferred from the tool-event stream renders dashed amber and never counts as done. Detection is forward-only within a 30-minute window, and never writes the declared stage. Workspace: one page at /run with a lane grid, the selected lane's pipeline, and a full Claude console behind a disclosure.

* @description Unit tests for the Logger class, which is responsible for logging messages in JSON format to stderr with different log levels (debug, info, warn, error). The tests cover writing logs to stderr, respecting minimum log levels, omitting meta when empty, and ensuring that each log line is valid JSON. The tests use Node's built-in test runner and assert module for assertions and mocking.
