Detailed Description

Layer X integration: the wave-1 diagnostics wired into the burn, the run record and the API.

What these hold (fast; the LE4 burns are tests/test_layerx_integration_le4.py, LAYERX_GOLDEN=1):

* **Defaults are today's.** Every new setting is ``None`` and resolves to the behaviour before it
  existed; the router mirrors them with the same defaults; the baseline's list of defaults is
  unchanged by their arrival.
* **GN2 on LOX** is refused for a hot fire on the physical criterion (nitrogen's saturation pressure
  at the LOX temperature, CoolProp), checked by hand, and runs with the acknowledgement.
* **The tanks at burnout** (preflight ``tank_rise``) follow the drawing's regulator law at the
  bottle's isentropic end pressure, re-derived here independently.
* **Limits** keep today's chug grade on the default basis with the settled and drawing-basis
  margins beside it (D7), and cap the new diagnostics at amber without touching the old limits.
* **Events** carry unique stable keys; **models** are flattened into the run record.
* **Router**: sidecars are written beside the run, served, pruned and deleted with it; exports;
  trade and optimise runs are listed as legacy.

LE4's DP-PT-R sits on the dome line of DPR_HP, whose loader is on the cart: the burn left the
line at atmosphere and the Stand page predicted 0.0 psig under a 550 psia dome (D-27). The
line's transducers read the dome signal; every other one reads the network as before.
