triblespace-core 0.40.2

//! `Workspace::commit` accepts `impl Into<Fragment>` so a Fragment
//! built via `entity!{}` (which may carry blobs from its `*:`
//! spreads or its own `Fragment::put` calls) commits *with* those
//! blobs absorbed into `Workspace::staged`. The blob bytes round-trip
//! through `staged.reader()`.
//!
//! Counter-test: passing a raw `TribleSet` works too (auto-promotes
//! to a Fragment with empty blob store), with no behaviour change vs.
//! the pre-Into-flip API.
