Build trust first.
Then build breadth.
This page explains the product path—not pricing, subscriptions, or a delivery schedule. Every future state is gated by quality.

The product path
Four phases. No invented dates.
- 01Baseline available
Prove the first model
Interactive calculators now demonstrate the calculation, formula evidence, and model boundaries. Production-quality checks and broader product capabilities still remain.
20 calculators available - 02In progress
Build the launch catalog
Implement the remaining tools only when each model, validation rule, source, teaching fixture, and interface meets the same standard.

Go deeper, not wider
Improve comparisons, local projects, reports, and the five core visual experiences. Depth must make decisions easier to inspect—not merely add controls.
Quality-gated enhancements - 04Direction
Scale with evidence
Expand toward more tools and independent learning pages only when search intent, method ownership, source quality, and maintenance capacity justify them.
Long-term direction, not a deadline

Release principle
Availability follows evidence, not a countdown.
Long-term goals—including a broader 120–160 tool portfolio—are directional targets. They are not release commitments.
