For better error handling and maintainability, it's recommended to raise a more specific exception than the base Exception. Using RuntimeError or a custom exception class (e.g., GitMergeError) would allow upstream callers to catch this specific failure more granularly.

Suggested change
raise Exception(f"Git merge failed: {merge_result.stderr}")
raise RuntimeError(f"Git merge failed: {merge_result.stderr}")

Bug: A failed git commit is not propagated as an error, causing the function to return a success status while files remain staged but uncommitted.
Severity: MEDIUM

Suggested Fix

After the run_git call for the commit, check if commit_result.returncode is not equal to 0. If the commit has failed, the function should return a dictionary indicating failure, for example {"success": False, "error": "Failed to commit changes"}, instead of continuing and returning success.

Prompt for AI Agent 
Review the code at the location below. A potential bug has been identified by an AI
agent.
Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not
valid.

Location: apps/backend/core/workspace.py#L836-L839

Potential issue: When a git commit operation fails within the
`apply_changes_and_resolve_conflicts` function, the code only logs a warning using
`debug_warning` and does not propagate the failure. The function proceeds to return a
success dictionary, such as `{"success": True, ...}`. This misleads the caller into
believing the commit was successful, when in reality the files have only been staged and
not committed, leading to a silent failure and a potentially inconsistent repository
state.
