I know how to chain Pokémon and I'm aware of what unique traits the chained Pokémon can have, but how does each level of the chain affect things like hidden abilities, maxed IVs, and shininess?
What are, numerically, the benefits of chaining Pokémon

Directly quoting someone who's read the compiled code, IVs, shininess, and hidden abilities are affected as follows:
It's not clear exactly what they were trying to say happens at a 70-chain for shiny chances - whether the chances max out at a 70 chain, or whether a 70 chain is the first point at which shiny chances increase, or what. We're already seeing people making conflicting assumptions about that. It's also unclear how this interacts with the Shiny Charm.
There's been at least one report of the chain counter overflowing back to 0 after hitting 255, resetting the above benefits. I've only seen one report, and no one who's read the code seems to have confirmed it, so it could be wrong.
Additionally, SOS chaining also provides improved EV gains. /u/foxhull on Reddit claims to have tested and found that all EV gains from an SOS battle are doubled, including EVs from the original wild Pokemon and from power items, stacking multiplicatively with Pokerus. Other people in the thread seem to agree.
SOS chaining does not boost your chances of getting a 5-IV or 6-IV.
