A collapsible Data panel under the Live Preview and Chart Builder charts shows the rows the chart actually uses, switching between Input (parsed source) and Resolved (post-transform) views read from the live Vega view. Collapsed by default; the open-state and a draggable height divider persist. Rows come through a new RenderHandle.inspectData() accessor, so no component touches the view: core/result-data picks the most-upstream source and most-downstream result from the compiled dataflow, read lazily. The divider reuses the window-splitter pattern (horizontal variant). Consolidations: a shared DataTable primitive replaces the inspector's and the builder's duplicate read-only tables; useResizeDrag merges the col/row drag-gesture twins. Docs: spec 04/06 and arch 05/10 updated; the now-shipped exploration memo removed.
Astrolabe
A browser-based snippet manager for Vega-Lite visualizations. Author chart specs as JSON, watch them render live, and keep a personal, searchable library — fully local, offline-capable, no account.
Astrolabe is a spec-driven rebuild on an architecture adapted from its sibling project Syto. The authoritative behavioral contract lives in
docs/spec/. See SOUL.md for the philosophy and docs/IMPLEMENTATION-PLAN.md for the build sequence.

Status
M0 — Skeleton. Toolchain green (typecheck, tests, build, PWA). The three-pane shell renders; features land milestone by milestone per the implementation plan (MVP at end of M1).
