# docs/exploration

Point-in-time records: research, tool reviews, and scope/planning memos written to think a
decision through. Unlike `docs/spec/` (the contract — the _what_) and `docs/architecture/`
(the maintained _how_), nothing here is kept current — each file reflects what was known
when it was written. Decisions that survived are folded into the spec and architecture;
these remain as the reasoning behind them.

Active follow-up work is tracked in [`../IMPLEMENTATION-PLAN.md`](../IMPLEMENTATION-PLAN.md),
not here. Exact figures in these files (timings, line counts, test counts) are frozen
snapshots, not live numbers.

- `chart-builder-research.md` — cross-source chart-choice research (Draco, Voyager, FT Visual Vocabulary, Datawrapper).
- `lyra-review.md` — review of vega/lyra for Chart Builder interaction ideas.
- `chart-builder-enhancement-scope.md` — consolidated Tier-B → Tier-C forward plan for the Chart Builder.
- `chart-theming-scope.md` — chart theming plan and slice breakdown.
- `monetization-and-sync-exploration.md` — monetization + BYO-cloud-sync direction memo.
