Resolving Merge Conflicts Like a Detective

Help! I have a merge conflict in our shared codebase and both sides look reasonable. Here's the conflict: interface User has name and email in HEAD, but the feature branch added permissions instead of role.

Before we pick a side, let's investigate like detectives: Questions to understand the INTENT: 1. What changed? HEAD added role, feature branch added permissions. 2. WHY did each side make this change? Maybe HEAD is simplifying auth? Maybe feature branch needs granular permissions? 3. Are they solving different problems? Role equals coarse-grained access, permissions equals fine-grained access. This isn't either/or! These are complementary. Resolution strategy: role controls general access level, permissions has specific capabilities. Admins have all permissions by default, users have limited permissions. This is how great codebases evolve - through conflicts that reveal better designs. Can you check the commit messages to confirm my hunch?

You're right! HEAD commit says Simplify user model and feature commit says Add granular permissions for feature X. So they're different goals that can work together.

Exactly! This is the key insight: Merge conflicts aren't battles to win, they're design conversations to have. The merge conflict is telling you: Two people made changes to the same thing. Figure out if they're conflicting visions or complementary improvements. Your resolution: Include both role and permissions in the User interface, with role controlling general access and permissions having specific capabilities. Admins automatically have all permissions, users have limited permissions. Post-merge action: Document this design decision! Add a comment explaining why both exist. This is how great codebases evolve - through conflicts that reveal better designs.
