Semantics. You can make it mean anything you like it to mean. There's a lot of fuzziness around the edges of all that. Just like the difference between a Condition 2 or Condition 3 when getting close to the split.
To me, stock is having parts either OEM or OEM replacement, same specs, dimensions, etc. Like using R46SZ plugs in place of the original R46SX plugs. It's what they superseded to for stock replacement parts. Or a suitable cross-referenced Wix air filter instead of the GM filter.
Bone stock means to me that the car had ZERO modifications to the car. It came from the factory just the way you see it. A new, unmolested car driven home from the dealership and first parked in the driveway is BONE STOCK. Some may make allowances for exact replacement soft parts like exact replacement tires and belts/hoses/fluids, batteries, but then I consider that in a category you didn't mention- Factory Stock.
Any added options that didn't come from the factory but were available for that year/model are mods the way I see them. Add a 4-bbl to a 350 that came with a 2-bbl.= mod. Add the underdash factory 8-track to a car that didn't come with one= mod.
JMO.

"Bone broth is essentially stock,"
Bone broth is made by simmering the bones and connective tissue of animals. This highly nutritious stock is commonly used in soups, sauces, and gravies. It has also recently gained popularity as a health drink.

I believe there are several varying degrees of stock.
1) Bone Stock = as assembled in factory, as delivered to dealership, as purchased by original owner. Maintained with that in mind by how many owners as a car has as long as kept original or restored to original.
2) Stock = same as above but with allowances. Replacement parts consistent with original configuration. As long as powertrain components are original units. Unenhanced rebuilds have no impact on status.
3) Stock but modded = my car. My powertrain, 350/350 combo with type O rear is original. To me that is the most important quality to any stock reference. However tons of mods prior to my ownership, aftermarket stereo, 4 wheel disc conversion, repainted from green to black, same with interior, wheels 15s, molding removed, etc.
4) Modded stock = An engine swap not matching original spec. Even if everything else is original. (455 in a otherwise stock 1972 350 CID 442, etc)
Modded = putting a 1969 Hurst/Olds entire powertrain in a 1979 Hurst/Olds. The kind of car that when you are asked if its stock you should immediately say no.

Then you probably believe there are several varying degrees of being pregnant...
Look, there are no legal definitions of "stock" or "bone stock". This is like arguing the distinctions of what's a big block vs a small block.
A car is stock if it is exactly the same as the configuration it was in when it left the factory. There's no fuzz on that. The slippery slope is replacement of normal wear items, which is why even organizations like AACA make distinctions of unrestored vs restored stock vehicles.
