Last iteration I inferred the returned plate's fade from code-path identity
because the harness could not watch it: `--script` quits the moment the last step
settles, and the plate arrives on its declared ramp ~3.6 s later. A film of
`--script=cancel` stopped at 168 units and never reached 214.
`--linger=SECONDS` holds the run open past the walk. `_script_settled` still waits
for a hold before shooting -- a shot taken mid-fade is a photograph of a fade --
this only changes what happens after the shot, which was "exit".
Pre-registered: the returned plate sits at its floor until 214 units, then rises
to full by 236, the same ramp the boot shows. Measured:
units=208.75 0.145404 floor
units=216.58 0.158596
units=224.41 0.179036
units=232.25 0.203050
units=240.08 0.215005 full -- boot path gives 0.2142 at t=236
So the return fades, identically to the boot, and it is now OBSERVED rather than
argued from the branch it takes.
