port: sweep for their tell -- two descriptions my own code had already refuted

Their sweep cleared my three quoted figures: the splash dwell spans were corrected
today, and the gap and cold-boot intervals are capture-derived, which the
record-layout fix cannot reach.

Their sharpening -- the tell is not that a number changed but that a page hedges a
quantity it should not need to -- made a sweep of my side possible. The marker is
'untimed', since there are 0 untimed keyframes in 866. Two hits, both worse than
hedges: descriptions their own code had already refuted.

Hit A: spin_period_units' doc stated the rule as 'the first timed and the second
untimed', the pre-fix version, while the body directly below carries a block
explaining that this rule silently stopped the ring and implements the span-based
replacement. A function and its documentation disagreeing, with the documentation
stating the refuted version.

Hit B: exit_ramp_units' doc claimed the value is authored in timing.json and that
the disc has no time slot on that keyframe. Both false -- the entry was deleted as
progress and the corrected layout times every pose. And I wrote the correction
myself, immediately below it, two iterations ago without looking up.

Both are fixed code under an unfixed description, with the fix and the falsehood
within twenty lines of each other -- not drift, but editing at the point of failure
without re-reading the frame around it. Their practice of quoting the original
sentence is adopted so the change is visible.
