dashboardManager

Search-visibility boundary for ASCII Maze browser and terminal hosts.

Evolution is difficult to trust when all you see is a final score. The dashboard boundary turns per-generation updates into a live board, a solved archive, and a reusable telemetry snapshot so long runs stay legible while they are still happening.

That is why this folder exists as a separate boundary instead of staying mixed into the engine. The engine should answer whether the search is making progress. The dashboard should answer how a human can see that progress: current best candidate, recent trends, species counts, complexity drift, and solved artifacts worth preserving.

Read the folder as three cooperating shelves. The public DashboardManager class keeps the stable host-facing API. dashboardManager.services.ts handles update ingestion, redraws, and telemetry emission. The archive, live, and telemetry subfolders keep presentation concerns decomposed so browser and terminal hosts can reuse the same core state with different outputs.

The chapter matters because telemetry without presentation quickly becomes a pile of numbers, while presentation without a stable telemetry contract becomes fragile host-specific logic. This boundary keeps those concerns close enough to cooperate and separate enough to evolve independently.

Read this chapter in three passes. Start with the class surface for the public update, redraw, and snapshot methods. Continue to the service module for the runtime dataflow. Finish in archive/, live/, and telemetry/ when you want the host-specific rendering details rather than the stable dashboard contract.

Example: create one dashboard instance for a run and feed it updates.

const dashboard = new DashboardManager(clearOutput, logOutput, archiveOutput);

dashboard.update(maze, result, network, generation, neatInstance);
dashboard.redraw(maze, neatInstance);

Example: read the latest public telemetry snapshot after several updates.

const telemetry = dashboard.getLastTelemetry();

console.log(telemetry.generation);
console.log(telemetry.bestFitness);
