Detailed Description

Layer X hardware read-outs: what the erosion replay keeps, and the hardware geometry built on it.

What these check, and against what:

* The replay keeps the per-step arrays the coupled solver computes (audit 5.2) without touching the
  keys it had. The new arrays are checked against identities that do not go through the code under
  test: the throat diameter against its area, the c* efficiency against its own breakdown, the
  throat station's recession against the old throat-recession key, the net load against its parts.
* An eroding engine is replayed on the coupled solver only (audit 5.3): a graphite-only engine,
  which used to replay through the legacy loop at zero erosion, now erodes; the legacy path refuses.

The replay here runs on LE4 (``configs/ethalox_6800N.yaml``) at synthetic line-exit pressures
through a minimal stand-in for ``Prepared``: the replay reads only the runner, the as-built
throat, the step and the ambient from it, and a twin burn would cost a minute per test.

Insulated slab, first mode only: T(L, t) = T0 - dT exp(-pi^2 alpha t / L^2) (Carslaw &
Jaeger 1959, ch. III). The back face rises from T0 - dT to T0, reaching 95 % of the rise at

supply_K is the supply's share of K0. The line exit zeroes K0, so the drop left is the exit
dump alone and holds no supply share; left in, the chug loop subtracted a supply drop from the

LE4's insert sits in the liner's phenolic out to the 304 case (~46 mm). Over a burn:

* the case stays at ambient: the phenolic's penetration depth sqrt(alpha t) is ~0.7 mm;
* the phenolic still draws ~k dT / sqrt(pi alpha t) ~0.4 MW/m2 from a ~2000 K insert, which a 6 mm
  graphite slab (rho c t ~7.7 kJ/m2K) feels as ~100-200 K over 3 s: the insert runs cooler and its
  throat erodes less than the adiabatic upper bound (no case declared, nothing behind the insert).
