Quick question if I may. I note when it was first showing up as available, it was "KCI2 Assure", then changed to 1 Stage. I assume 1 Stage is the better one to have.
This is more j0hn's domain I would humbly suggest, as he is on 'that side of the fence'. But as an educated guess, I would absolutely say 'Stage 1' is the better of the two ..... simply because a job wouldn't progress through to 'Stage 1', without an active order in play.
j0hn's systems/terminology may well be different to mine ..... but it's very simple in my eyes ..... the infrastructure from HE to CBT is fully in place and has gone to CRFS (Customer Ready For Service).
Once the EU places an order, the OR systems will either recognise straightaway that the order requires moving to 'Stage 1', due to the 'Survey Network Notes' that are recorded against each premises (a prime example being a partial DiG estate).
Or, it will go direct to an installation date if the SNN marker states 'Fluid duct' etc etc.
However, as is such, the installation engineers may well find an issue on the day, that then requires it moving to 'Stage 1'.
Either way, relax and let it run its course. You'll soon have FTTP
