port: the oracle harness was nondeterministic and I quoted it for a dozen iterations

verify-capture's main_menu row reads 13.30 / 13.27 / 13.25 / 13.26 across runs
this session while every other row is identical to the digit. I cited those
numbers repeatedly, including in the rest() adjudication.

Cause: the focus ring spins on time_units raw rather than the pose clamped by
holding -- deliberate and correct, since the ring is the one thing on a settled
screen that keeps moving -- so its angle at capture is set by the wall clock.
extras is stable because nothing there spins.

--loop-phase already existed and did not cover it: it pins the looping focus
record phase, while the spin is a second free-running clock I guarded once and
never connected. Extended loop_phase_units to pin the spin too, and verify-capture
now passes --loop-phase=0 at all four render sites.

The control matters because the drift was intermittent -- three unpinned runs gave
13.25, 13.26, 13.26, so three pinned runs agreeing would prove nothing. Phases
0/30/60/90 give 13.2583 / 13.1991 / 13.2637 / 13.2588: the pin is live and the
0.065 spread is the whole of the observed drift.

Non-finding recorded so nobody mines it: phase 30 scoring lowest is not evidence
about the ring's real phase -- 0.065 against a ~13.2 gamma floor is 200x too
small. A margin only means something against the noise it sits on.

No conclusion changes: the smallest margin any of them turned on was 0.14%
differing area.
