  "arms_f": "b is the slower half's largest natural rate, computed from nudge_test's rates (0.95021 to five places).

The slower half and the free turners keep their rates. Same copied step; from R, nudge_test's own step",

Run 1 is at c0 = 0.99527. A run is accepted, ending the search, when |f(c)| is at most 0.01 times the raised arm's C at R. Otherwise: if an earlier point (c = 1 included) has the opposite sign, the bracket is that point nearest in c and the newest run; once a bracket exists, each new run replaces the end with its own sign. Inside a bracket the next c is false position, replaced by the midpoint if it falls outside the bracket's middle 80%. Without a bracket the next c is the secant through the two most recent points (the first time: c = 1 and c0), raised to 0.95 if it falls below; the moment is unmatched if that secant is undefined, points to c of 1 or more, or repeats a c already tried. At most 8 runs. A moment with no accepted run is unmatched, with its reason, and keeps the readings of its closest run, marked unmatched. Nothing is retried or loosened.",
  "rule": "Directions: in each group, the faster half's pulled oscillators (|omega| > b, |omega| at most 20) with omega > 0 (forward) and omega < 0 (backward), 968 each, by their original rates. Turning rate: each oscillator's advance over (T + 150, R], summed from readings one time unit apart, each unit's advance being r + wrap(arg(u_t conj(u_(t-1))) - r) with r its natural rate in use during the window; divided by 50. w(t): the mean of e^(i theta) over a direction's 968, read every unit. Backward rates are negated, so its band is -1.30 to -0.80. L: the most turning rates any closed interval [x, x + 0.03] with 0.80 <= x <= 1.27 holds, divided by the most natural rates in use (of the same 968) any such interval holds; candidate x are every rate from 0.80 to 1.27, and 1.27. Ties go to the interval nearer the centre (rate 0): the smaller x. Omega*: the median turning rate in the chosen interval, sign restored. S: |the mean over t = T + 151 to R of w(t) e^(-i Omega* (t - T))|. A direction holds a rhythm if L >= 1.5 and S >= 0.057; a group holds a counter-rotating pair if both directions do at the same moment; steady: S >= 0.057. With no turning rate in the band, Omega* and S are undefined: no rhythm, not steady.",

Old start 1 (seed 0): a base run to t = 100 (states kept there), short arms of 20 units changed and 20 restored with both copies, the copy with readings every step over 10 units, and arm U's 200-unit window against its mirror at c = 0.99527 and c = 0.95. Pilot start 103 (seed 102), its first moment (T = 2,055): the raised pull and the untouched rerun, both copies, 200 + 500 units, against the medium pilot's saved arrays. The rule on made-up phase histories drawn from (20261015, 9, scenario), with no model run.",
  "step_2": "Old starts 16 and 17 (seeds 15 and 16), 10 moments each by the medium pilot's rule and draws. Base runs made afresh by the medium pilot's own function, keeping the states at T and R and no gap growth. At each moment, from the state at T, the first copy only: the untouched window, the raised pull, arm F (0.6), arm F-prime (0.4) and arm U's search, 200 units each. Nothing after R is run or looked at. No labels are applied to its numbers, and they never enter the pilot's readings."
