• A reported hyperparameter bound that left the node range now says so
  (#390). An endpoint past the outermost NODE is produced by the
  outside rule -- extend mirrors a half-cell beyond the outer coordinate --
  so it is an extrapolation rather than a bound the design supports.
  theta_ci_outside_nodes records it per axis ("lower" / "upper" /
  "both" / NA), the same rule that makes a declined placement say so
  (#293). Recorded rather than corrected: the two used to be
  indistinguishable on the fit.

• The recentred axis's mode-SD ceiling is settled: max_sd_u = 3 is kept, on
  evidence. #387 could not score its VALUE because every ladder
  came back flat or non-monotone. The reason was the LEVEL, not the fixture.
  Over 48 (cap, span, node-count, clamp-policy) rungs on two ceiling-reaching
  fixtures at 200 seeds, the reported bound leaves the node range on 56-90% of
  fits at nominal 0.95 at EVERY setting and on 0% at nominal 0.50 -- so 0.50 is
  the level whose bound the design supports, and 0.95 is where the earlier
  ladders were measuring the extend rule instead.

  At nominal 0.50: the cap is EXACTLY inert at nine nodes (1.5, 3 and 6 give
  identical coverage to three decimals in 7 of 8 cells); at the shipped five
  nodes, 3 is nearer nominal than 1.5 at span = 4 (0.450 / 0.415 against
  0.370) and ties at span = 2.5; and 6 reaches 0.520 only on a doubled width.
  Under the shipped sd_clamp_policy = "decline" a lower ceiling also is not
  free -- dropping to 1.5 abandons the placement on 32-39% of fits. span and
  n_pts are kept with it: nine nodes moves 50% coverage FURTHER from nominal
  while costing proportionally more inner solves.
