Detailed Description

The watcher (``feedtwin.session.watch``), and the faults it found first.

A clean LE4 (6) burn and abort raises no flag and keeps its mass; each check
fires when its condition is put into a real stand; flags are episodes, not
ticks. And the two faults the watcher turned up on its first runs:

* The chamber of a drawing with no engine model counted any flow touching it
  as "lit", including flow *out* of it: after a burn it stayed at its drawn
  385 psia, and an Engine Abort's open mains drove 3 kg/s from the dead engine
  back into the tanks -- 16 kg the mass balance could not account for.
* A tank the cart loads through the drawing credited any liquid arriving at
  its outlet, wherever it came from: at Fire on unpressed tanks the chamber's
  push-back filled a full fuel tank 46 g a second, and on a longer pad
  overfilled it ("tank is overfull") and stopped the stand.
