Your phrasing and terminology are confusing me . . .
That said, I think I know what you're getting at
After the vacuum hose was reconnected, the fault codes were cleared, which extinguished the check engine light
By clearing the fault codes, all of the readiness monitors automatically reset to "incomplete"
A week later you went to get the car smogged, and the catalytic converter and evaporative emissions monitors were still incomplete
In a sense, the truck failed the smog inspection, because of incomplete readiness monitors
Your catalytic converter and oxygen sensor have not failed. you don't have any failures, in fact.
You simply haven't driven the truck in the proper method to result in the completion of those readiness monitors
I suggest you do a google search on how to set readiness monitors, specifically catalytic converter
I'm not sure what year your Explorer is, but in all likelihood, if you show up with all monitors complete, except for evap . . . which can be quite difficult to complete . . . the truck will be considered ready for testing, at which point you'll most likely pass, unless you fail the tailpipe test, the inspector detects tampering, missing emissions components, etc.
To sum it up . . . I believe if you concentrate on only completing the cat monitor, and ignore the evap monitor, for now, you'll be good to go, when you show up at the smog testing facility again
Most test facilities allow you one incomplete monitor. But depending on your location, model year, etc., that incomplete monitor can NOT be catalytic converter
Do NOT throw parts at the truck
Do NOT clear the codes again, in an effort to "start anew"
Do NOT use any "cleaner" in your tank
concentrate on completing that cat monitor
you're almost there
