+# Science
+
+`science` is the native offline science workbench from
+[`keys-i/tools`](https://github.com/keys-i/tools). It owns three focused views:
+JPL-based approximate planetary positions for 1800-2050, bounded VCD logic
+traces, and streamed ASCII or little-endian binary PLY and 32-byte `.splat`
+point clouds.
+
+Choose `snapshot` for stable plain or JSON output inside Scripts. Choose `open`
+to show the exact command for an interactive terminal. Wave input is capped at
+64 MiB and 2,000,000 distinct changes. Clouds are capped at 50,000,000 points;
+full statistics are single-pass and rendering retains at most 60,000 evenly
+spaced points.
+
+Wave parsing preserves distinct multi-bit values and drops only consecutive
+identical states.
+
+The `action` selects `snapshot` or `open`; `view` selects `orbit`, `wave`, or
+`cloud`. Supply an `input` file for wave and cloud, optionally offset orbit by
+`days` through `--days`, and choose the snapshot `format` as plain text or JSON.
+
+No network service, serial driver, shell, Python process, upstream executable,
+or copied asset is involved. The prepared `keys-tools` PyPI package has not
+been published.
