The past two weeks marked a shift from architectural direction into full execution. The WinForms elimination effort moved from plan to action, with large portions of the legacy UI removed after their React equivalents were validated. This was not a gradual transition. It was a replacement-first approach that resulted in a smaller and more coherent codebase aligned to the forward architecture.
At the same time, the shell platform reached a level of maturity where it can support the full application structure. What began as scaffolding is now a defined infrastructure layer with contracts, routing, and workspace state management. This enabled delivery of the first complex guided workspace in the Plan and Schedule interface. Configuration and execution domains were brought into the shell, documentation was consolidated into authoritative references, and the test suite expanded alongside the growing surface area.
