## SQL And Preview Safety
The SQL workbench parses one `SELECT` statement into the canonical graph. The
dialect supports projection, aliases, filters, grouping, aggregate functions,
sorting, limits, `DISTINCT`, and one two-source equi-join. It rejects DDL, DML,
subqueries, arbitrary functions, file access, and unchecked pass-through
execution.

Preview reads at most 250 rows per source and enforces time, intermediate-row,
result-byte, graph-node, and response-row bounds. Saved previews record the
pipeline revision, executor version, source fingerprints, node diagnostics,
and output summary, but not source or result rows. A preview may return one
explicitly requested intermediate node state under the same response bound;
that row payload remains ephemeral and is not added to run evidence.

targets the selected graph node and supports remembered automatic or
manual-refresh preview modes.
Saved revisions can also be started through the versioned
`dataflow.runLifecycle` capability or the Run dialog. The first runner is
