§4 Chunk 03 — SESSION
Session portability — panes, filters, and scroll position travel inside the .dat0 file, so whoever opens it lands where you left off. Designed, not shipped.
SESSION0x03F8
In development. This format is designed, not shipped. Nothing to install yet — join the waitlist.
The SESSION chunk is the workbench, as you left it. Panes, filters, column widths, the row you scrolled to — the state of the grid seals into the file with everything else. Whoever opens the artifact lands where you left off: the grid you left is the grid they open.
Why it matters
Analysis is a place, not just an answer. When a result travels without its place, the next person rebuilds the view before they can check the work — re-filtering, re-sorting, scrolling to find what you saw. A session that travels inside the file skips all of that: the conversation starts at the finding, not at the setup.
The chunk
The payload is small on purpose — workbench state is a layout, not a dataset: pane arrangement, active filters, sort order, the scroll offset. Restore it and the workbench looks exactly as it did at seal time, on your machine or on someone else's.

§3 Chunk 02 — QUERIES
One query, any source — join a Parquet file on disk to a live Postgres table in a single query, no ETL. The QUERIES chunk keeps the saved questions. Designed, not shipped.
§5 Chunk 04 — LINEAGE
Lineage proof — a sha-256 chain of step hashes and source fingerprints, so every number in a .dat0 file is traceable to the byte. Designed, not shipped.
