Detailed Description

LE4 burned with every diagnostic wired in: the baseline must not move, and every block must be there.

Slow (three LE4 burns, ~6 min): skipped unless ``LAYERX_GOLDEN=1``, like tests/test_layerx_golden.py,
whose baseline, config and tolerances these use.

* **he_pad, diagnostics on** (as the router runs every burn): the golden figures are reproduced
  within the golden bands (the diagnostics read the burn and change nothing in it), every
  DATA-CONTRACT 3 block is present with its contract keys and finite numbers, the limits follow
  the coordinator decisions, every event has a unique stable key, the run record lists every model,
  and the diagnostics cost under 10 % of the burn.
* **he_flight**: the helium hot-fire drawing flies now that the flight prices its ullage and refill
  as helium. It reproduces the baseline's "He ullage" what-if (AUDIT 8 first gave 24,235.2 N·s, 3.4461 s, apogee
  3,249 m AGL), which reached it by patching the config and flying the retired RocketPy outer loop.
  The burn settles on the pad first -- the same burn as he_pad, figure for figure -- then flies
  with the 1-DOF ascent stepped inside it (AUDIT D5-C), within 0.5 % of RocketPy's specific force.

Every burn records the whole feed network (``result.network``, DATA-CONTRACT 2, wired 2026-10-03), so
the blocks that read it (ladder, regulator, solenoids, saturation, the pressurant floor, the stability
block's start window) must all be there, and agree with the AUDIT's own hand figures for this burn.

* **The AUDIT's trip** (section 5, #1): TK-FUEL's MAWP restated (600 psi in the AUDIT, 585 psi since
  the default lockup became the drawing's dome). Before the wiring Layer X
  integrated the frozen stand to the 14 s horizon (99,478 N s, "Horizon reached", no trip). Now the
  burn stops where the tank crosses 614.7 psia (~3.1 s): its impulse, delivered impulse and burn time
  end there, it carries ``tripped``, a ``fail`` event keyed ``trip``, ``converged`` false, and a bad
  ``vessel_trip`` limit, with every diagnostics block still built.
