Change log

  • 12 November 2026 — Version 1.6.4: restricted educational pool and electrical models now start blank, require explicit pool measurements and product strength, and keep scope notes with exported results. Removed the voltage-drop gauge suggestion; reassessment is attributed to AI reviewers without claiming qualified human approval.
  • 11 November 2026 — Version 1.6.3: corrected material and manufacturer-example wording, removed an unsupported fixed deck-fastener estimate, corrected zero-load wire-reference output, and tightened publication links and cache handling. AI-assisted review is identified separately from qualified human specialist approval.
  • 8 November 2026 — Version 1.5: added concrete, mulch, paint, drywall, square footage, pavers, stairs, fences and grass seed; corrected two area displays, removed initial form layout shifts and reduced asset requests.
  • 8 November 2026 — Version 1.4: corrected live-result invalidation, fraction and unit handling, room AC chart, pool concentration math, wire-reference data, lumber kerf, deck edge gaps and wainscoting positions; simplified mobile forms and added task-specific FAQs and reference sections.
  • 6 November 2026 — Version 1.3: corrected roof purchase boundaries, resin input modes, flow and filament displays, binding edge cases, result freshness and publication controls; expanded documentation for the 60-tool collection.
