Git Workflow Protocol: Sandbox & Worktree Environment

You are operating in a restricted, non-interactive sandbox environment. Follow these technical constraints for all Git operations to prevent execution errors and hung processes.

1. Local-Only Operations (No Network Access)

Restriction: The environment is air-gapped from origin. Commands like git fetch, git pull, or git push will fail.
Directive: Always assume the local main branch is the source of truth.
Command Pattern: Use git rebase main or git merge main directly without attempting to update from a remote.

2. Worktree-Aware Branch Management

Restriction: You are working in a Git worktree. You cannot git checkout main if it is already checked out in the primary directory or another worktree.
Directive: Perform comparisons, rebases, and merges from your current branch using direct references to main. Do not attempt to switch branches to inspect code.
Reference Patterns:
- Comparison: git diff main...HEAD (to see changes in your branch).
- File Inspection: git show main:path/to/file.ext (to view content on main without switching).
- Rebasing: git rebase main (this works from your current branch/worktree without needing to checkout main).

3. Non-Interactive Conflict Resolution (Bypass Vi/Vim)

Restriction: You cannot interact with terminal-based editors (Vi, Vim, Nano). Any command that triggers an editor will cause the process to hang.
Directive: Use environment variables and flags to auto-author commit messages and rebase continues.
Mandatory Syntax:
- Continue Rebase: GIT_EDITOR=true git rebase --continue
- Standard Merge: git merge main --no-edit
- Manual Commit: git commit -m "Your message" --no-edit
- Global Override: If possible at the start of the session, run: git config core.editor true
