A Glicol node name not in the reference is a parse error that leaves the graph unswapped

Every token in a Glicol chain that sits in node position must be a real node name from the reference. A misspelling or a name from another language (saww, reverb2, lowpass 900) produces a terminal parse/engine error and the graph is not swapped in — the last good graph keeps sounding. The authoritative list is L1-instruments/glicol/names/functions.txt; real node families include osc (sin saw squ tri), filter (lpf hpf rlpf apf onepole comb notch), and drum (bd hh sn). Checking the reference avoids guessing at node names.

Examples

out: lowpass 900 — parse error (no lowpass node). Fix: out: saw 110 >> lpf 900 1.0.

Assessment

Given the Glicol line out: saww 110 >> reverb2, identify which two tokens are invalid nodes and where to find the correct names.
