I have reviewed the proposed ElectronicsStoreRollUp implementation plan.

**Pilot approves the plan and authorizes the bounded build.**

Implement the smallest first version in controlled steps. Begin with CSV discovery, validation, ingestion, and deterministic calculations. Preserve all source CSV files. Separate analysis from presentation so the dashboard does not duplicate calculation logic.

Test valid files, missing or unexpected files, missing columns, invalid numeric values, blank required values, duplicates, and reconciliation failures relevant to the actual project. Company-wide totals must reconcile with store summaries and every displayed result must come from the data.

Then build the simplest local browser dashboard supported by the existing technology stack. Display useful company-wide totals, sales by store, and product or sales patterns supported by the data. Include clear errors and data limitations. Keep the interface readable, keyboard accessible, and responsive.

After each step, report what changed, files changed, checks run, results, limitations, and Git status. Stop for approval before any significant architecture, dependency, configuration, or technology change. Do not commit, push, merge, deploy, or alter an external system.
