In response to @ciro-santilli-%e9%83%9d%e6%b5%b7%e4%b8%9c%e5%86%a0%e7%8a%b6%e7%97%85%e5%85%ad%e5%9b%9b%e4%ba%8b%e4%bb%b6%e6%b3%95%e8%bd%ae%e5%8a%9f detailed in-depth look at the index, am sharing output for one of the TODO.

"If you git add, then a stage 0 is added to the index for the path, and Git will know that the conflict has been marked as solved. TODO: check this."

And, more specifically, the different merge stages.

• 0: regular file, not in a merge conflict
• 1: base
• 2: ours
• 3: theirs

Details on the numerical representation of the various stages, in this case a file with conflict.
