The last WT step in 0.17 is to sleep and then get note from fridge. The first Step in 0.18 is : after reading note from fridge, go to front door (notice that these Steps are very similar and the 0.18 Step is the one that matters).
That should be where you're at in your playthrough.
But I'm no techie and do not touch other players' saves, or share my own saves (when I tried that, I was told off basically because of my lack of techie skill), or judge their purity.
The inventory search, together with reading the WT, can tell a player where he ISN'T. For instance, in 0.17 Joey gave Linda some dirty clothes to launder for him. These clothes have remained in my inventory since then. To not have those clothes would suggest a player has not reached the end of 0.17.
