Engineering track
Dual-standard engine (NEC 2023 + CEC 2024)
Rule packs lock per-project; standard guard at API + engine level prevents cross-pack pollution. Live since v7.0 (2026-05-14).
Voltage drop with temperature-corrected R
Temperature-corrected conductor resistance everywhere — not book-rated. Built into derive() since v7.0.
Single Line Diagram canvas (IEEE 315)
28-symbol palette, click-to-wire state machine, L-shaped auto-routing, live calc overlay, single-page landscape print with title block. v7.4 (2026-06-01).
24 free calculators
Cable size, voltage drop, fault current, arc flash, conduit fill, breaker sizing, transformer sizing, demand factor, panel schedule, and more. Dual-standard where applicable. v7.2 (2026-05-29).
Short-circuit / fault current engine — workspace integration
The standalone calculator ships; embedding into the workspace derive() pipeline with available-fault-current at every bus + OCP interrupting-rating check is in progress.
Compliance topology checks
TOPO-001..004 surfaced in the workspace — orphan glyphs, missing wires, ref_node_id mismatches, unrouted services.
Arc flash incident energy in workspace
NFPA 70E 2024 + CSA Z462 2024 methodologies into the SLD canvas — label generation per panel/branch.
Selective coordination checker
TCC curve overlay with clearance check between upstream and downstream OCP.
Harmonics / power quality
IEEE 519 distortion limits, K-factor transformer sizing recommendations.
Grounding system design
NEC 250 / CEC 10 — service grounding, equipment bonding, earth electrode resistance.
Product track
Workspace v4
Five-pane shell, 9-stage workflow, tab-based modules, inspector with provenance, command palette, density modes, dark theme, server-roamed layout. v7.2 (2026-05-29).
Reports v1 — 8 RPT codes + EXPORT-ALL

8 case studies (worked examples)
4 NEC 2023 + 4 CEC 2024 reference projects available as live demos in the dashboard. v7.4.
Mobile structural pass
Long-press → context menu on touch, 40+ px hit targets, slide-in drawers for tree + inspector, single-col welcome layout, SLD toolbar wrap. v7.4.
Equipment library expansion
Panelboards, transformers, ATS, breakers — manufacturer data with SCCR, AIC, dimensions. 40+ items seeded; expanding to 200+ across Square D, Eaton, Siemens, ABB, Schneider.
Reviewer mode
Read-only project view with annotation, comment threads, and an exported review-pack PDF.
Video library
First videos shipping with the 2026-Q3 release. Filming plan published at /video-library.
Plan-review hand-off package
One-click bundle: PDF + audit log + change history + reviewer instructions, ready for AHJ submittal.
Mobile field view
Read-only project on phone for site walk-throughs and quick load adds. Q5 mobile pass laid the structural groundwork.
AutoCAD MEP / Revit two-way sync
Round-trip with mainstream CAD tools via published JSON schema.
Platform track
Admin console
Org / team / subscription management; super-admin role with audit-logged actions. v7.0.
Fly.io migration
Backend moved from Railway to Fly.io (yyz Toronto) for sub-100ms NA latency. 2026-05-20.
Realtime multi-tab sync
WebSocket broadcasts structural mutations across every tab on the same project. v7.2.
SSO (SAML + OIDC)
Enterprise login federation with Okta, Azure AD, Google Workspace. Auth surface ready; per-IdP setup flow in progress.
SOC 2 Type I
Audit kick-off Q3 2026; report target Q1 2027.
Public API for partners
Stable REST contract for partner integrations. Internal surface used by the workspace today; public versioning + rate-limit policy + tokens for external consumers next.
