One workspace for the commissioning trail

Archie reads the project's drawings, models, specifications and schedules, then computes every quantity, allowable and test pressure with a deterministic engine.

MSD/L02/0221 is the one to chase first: it is not installed yet, so it blocks the RA-01 leakage test as well as its own drop test. The other three are installed and only need witnessing.
