I think you're making the vapor barrier too complex. Last basement I finished the concrete was cleaned/etched with muriatic acid and sealed with exterior concrete paint from Sherwin Williams. Moisture was contained and I didn't have to worry about plastic sheeting getting abraded and failing.
jmo,
How far above the water table is your slab?
How well drained is your foundation?
What's the permeability rating on the paint at the applied thickness?
Did you put down a wooden subfloor? If yes, did you put any insulation underneath it? If not, what is the average subsoil temp in your area?
A lot of factors go into whether you actually need a vapor retarder on a slab, and how vapor retardent it needs to be. And there's a huge difference between making something waterproof vs. vapor retardent, the difference between liquids and gas. Most exterior paints have moderate to high vapor permeability (and its a good thing too, or you'd be trapping moisture in walls creating mold problems). If you think you've vapor-sealed the slab with the paint, read the fine print on the specs, 'cuz I doubt it. Sealers & paints can slow down capillary transfer of liquid moisture in masonry though, and maybe that's all you needed.
In a basement with a history of bulk water incursions, in a climate zone with high summertime dew points and subsoil temps of ~50F, putting both a class-I vapor retarder and some insulation underneath a wood subfloor is a reasonable precaution, and the installation doesn't have to be perfect to make it work.
My basement slab is typically less than a foot from the water table, the slab temp (uninsulated) stays in the low 50s year round, and sealing it with a masonry sealer has pretty much halted capillary draw. But a cardboard box left on the floor will develop mold on the bottom if left for months, even in the drier-air winter months. In the humid summer when the room temp is ~65-68F and mechanically dehumidified to 60% RH, a box left on the floor even with a sheet of poly under it will develop mold after 6-10 weeks, an artifact of the temp at the bottom of the box being at or near the dew point of the room air is that it eventually accumulates enough moisture to grow mold. His place in CT isn't that far from my place in MA- temperature conditions at the slab and summertime air humidity are likely to be more similar than different.
