Update Branch

Rebase the current session branch onto the latest upstream so the work stays grounded in origin.

Workflow

1. If there are uncommitted changes, use the /commit skill to commit them first.
2. Fetch the latest upstream and rebase onto it:

   git fetch origin
   git rebase origin/main
   

   Use the appropriate base branch if it is not main.

Conflict Resolution

When conflicts arise, upstream always wins:

• Never alter upstream logic, APIs, or patterns to accommodate session changes.
• Adapt session work to fit the new upstream — rename, restructure, or rewrite as needed while preserving the session's goals.
• After resolving each conflict, git add the files and git rebase --continue.

Validation

After the rebase completes, verify the result still compiles and meets the session's objectives. If session changes no longer make sense against the updated upstream, explain what changed and propose a revised approach.
