Audited SPEC.md against code — mostly accurate but redundant with repo-map.md and design-principles.md. Minor drift in storage internals, wizard step count, and mode representation. Salvaged product vision and non-goals into docs/design-notes.md with staleness disclaimer. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# Design Notes

|
|
> **Staleness warning:** This document captures conceptual framing from the
|
|
> original specification. It is not kept in sync with the code. For current
|
|
> architecture and types, see `context/repo-map.md` and
|
|
> `context/design-principles.md`.

## Product Vision
|
|
|
|
Traditional spreadsheets conflate data, formulas, and presentation into a single
|
|
flat grid addressed by opaque cell references (A1, B7). This makes models
|
|
fragile, hard to audit, and impossible to rearrange without rewriting formulas.
|
|
|
|
Improvise treats data as a multi-dimensional, semantically labeled structure --
|
|
separating data, computation, and views into independent layers. Formulas
|
|
reference meaningful names, views can be rearranged instantly, and the same
|
|
dataset can be explored from multiple perspectives simultaneously.
|
|
|
|
The application compiles to a single static binary and provides a rich TUI
|
|
experience.
|
|
|
|
## Non-Goals (v1)
|
|
|
|
- Scripting/macro language beyond the formula system.
|
|
- Collaborative/multi-user editing.
|
|
- Live external data sources (databases, APIs).
|
|
- Charts or graphical visualization.
|
|
- Multi-level undo history.
