Subject: [PATCH] Hands mover: on 0.3.18 trees the restart read-back takes
 powEngine and the blockrate object from igneum_getNodeInfo; a stub answer
 stops the sequence

The shipper's read-back for 0.3.18 (7 October 2026): igneum_getNodeInfo exists again and must answer powEngine igneum-pow (a stub
is a FAIL) with a blockrate object, which the mover prints; a tree before 0.3.18 answers -32601 and the engine is still read from
the binary's igneum-pow source paths. The parser is checked against the three answer shapes.
