@ maynardGkeynes,

The report uses the term "movement," which would seem to cover that:
Thanks, movement is indeed what the report uses for system description. This seems to cover the issue when movement is interpreted as "any" movement. Perhaps the fuel cut-off switches (switch position) and spars are also separately recorded parameters.

The report also mentions - quote: "Any uncommanded movement would have been recorded on the FDR and warnings would have been enunciated on the flight deck." - unquote. Regarding the warnings, they would indeed be enunciated, but only if there is a disagree between the spar control relay and spar valve position (stuck valve). Apparently no warnings if the valves, slaved to the control relays (not the cut-off switches), follow relay command if i'm correctly interpreting system operation . . . but i could be wrong.

Anyway, the report is quite definitive regarding movement being recorded so i will leave it to the experts involved with the investigation.
