- Step through: the engine's debugger in the tab (wasm engine_debug) or the
app, a slider forward and back, the next step named with its line and its
gate marked on the diagram; each qubit's phase disk with a purity ring and
its Bloch sphere in plain SVG; the amplitude and phase table; the reduced
state of chosen qubits; under noise the noisy state against the noiseless
one; and the branch tree with its weights, a branch chosen to put the path
on it.
- Editing by the drawing: a palette gate dropped on a wire, a drawn gate
dragged to other wires or places, or moved and deleted from the keyboard,
each made by the engine in the program's text (engine_visual_edit) and
recorded as the reader's edit; a gate its statement does not make alone is
refused with its line.
- The diagram described to a screen reader in the engine's words, and the
drawing saved as the engine's SVG or LaTeX (engine_picture).
- The desktop app answers the same calls natively (debug off the window's
thread). The wasm workflow's counts are 16 native and 9 under Node; the
Studio's browser test checks each view.
