the one that i am putting in which definitely qualifies is to use this
wires distributed strategically throughout the processor with analog
ring circuits (a PLL in effect) will be affected by local EMF. thus by
any given program, the frequency will change (HP's Signature Analysis
was a bit more sophisticated but you get the idea).
it then becomes possible to create an audit trail showing the results of
running a program and if the silicon was ever tampered with (some rogue
unauthorised transistors) they will show up *even if not active* because
they will change the layout characteristics.
sounds like the idea I came up

it's close enough so yes.
bear in mind we'll still be under time pressure and have chosen
the Scoreboard system due to its power consumption saving, so
the "Shadow/Cancellation" system will need to be part of that.
(Shadow-Cancellation "holds off" any "damage" by preventing
and prohibiting anything that is executed speculatively from
causing writes, until it is 100% known that it will not need to
be "undone". this is the total opposite of "Rollback" strategies
which take full snapshots and back them out if there was ever
an "undo" needed)
