[0.2.0] - 2026-03-27¶

134 known tools across 19 categories — massively expanded from the original 27, now covering AI (including local/privacy-focused models like Ollama, Mistral, LM Studio), databases, data visualisation, geospatial, payment processors, website builders, hosting, and more
Cost analysis in review — total annual cost, breakdown by function, top 3 most expensive systems, and count of free/uncosted tools
Overlap detection — warns when you have multiple systems of the same type under one function, suggesting consolidation opportunities
Clickable stepper — completed wizard steps are now clickable links, so you can jump back to any section to edit
Mobile stepper navigation — left/right arrows for moving between steps on small screens
Form hydration — going back to a previous wizard step now shows your existing data, not a blank form
Clear and start fresh — the path selection page detects existing data and offers to clear it with confirmation
Organisation types expanded to include co-operatives and private businesses
TechFreedom acknowledgement — credit to TechFreedom programme in the review summary and footer
Documentation link in the footer
Cost data included in JSON export — export now includes a costSummary object
Cost column in TechFreedom risk table — see cost alongside risk for each system

Landing page redesigned — replaced generic AI-style layout with distinctive design: leading question headline, real GDS sector stat, staggered "how it works" steps, asymmetric layout
Smart cost estimation — replaced simple size multipliers with realistic per-seat pricing, tiered pricing selection, and penetration rates (e.g. not everyone needs a Salesforce licence)
Wizard navigation is now non-linear — users can step forward and back freely, editing at any stage
Sidebar redesigned — now an expanding overlay panel (480px) instead of a cramped fixed sidebar, with floating pill on mobile
Footer updated — built by The Good Ship and tomcw.xyz, MIT licence, TechFreedom credit, docs link
480 tests across 42 test files (up from 335/30)

Duplicate systems bug — going through the wizard twice no longer creates duplicate functions and systems
State not persisting to diagram view — architecture now auto-saves to localStorage on every change
Service-first path now fully functional (was "coming soon")
