Detailed Description

The whole network, sampled at every step of a burn. Absolute SI.

Built by :meth:`of` from a session, then fed each :class:`Sample` by
:meth:`append`. Columns are as long as the burn's ``t``.

◆ of()

"NetworkTrace" feedtwin.session.network_trace.NetworkTrace.of	(		cls,
		"Session"	session )

The static description of ``session``'s network, columns empty.

◆ record()

dict[str, Any] feedtwin.session.network_trace.NetworkTrace.record	(		self,
		Iterable[float]	t )

The contract's ``result.network`` block: psia, psi, K, kg/s.

``t`` is the burn's clock (``BurnTrace.t``), carried so the block stands
on its own.
