July 2026 monthly summary for tscircuit/core: Focused on visual fidelity and data propagation across the rendering pipeline. Delivered a bug fix that propagates solderMaskColor and silkscreenColor from the board component to the pcb_board in circuit-json, ensuring downstream consumers (e.g., 3D viewer) render the intended colors. The changes restored test reliability and aligned the data model with UI rendering expectations.

June 2026 — tscircuit/footprinter: strengthened footprint validation and quality gates by introducing an automated SOT-89-3 footprint validation test against KiCad reference. This delivers earlier parity checks, documents real-world geometry mismatches, and guides targeted footprint corrections, reducing manufacturing risk and QA toil. The work is tracked by a focused regression test (commit e8c173c516766819d97b882bce8152dcedcb2559) with co-authored-by collaboration.
