Problem

timmy-config #359 had 3 APPROVED reviews from Timmy on a PR with zero additions, zero deletions, and zero changed files. This is rubber-stamping — the review process produced approvals where there was literally nothing to review.

This erodes trust in the entire review system. If agents can approve empty diffs, the approval signal becomes meaningless.

Root Cause

Timmy's review automation does not check whether the PR actually contains changes before issuing an approval. It likely runs a loop like "for each open PR, post APPROVED" without validating the diff.

Solution

Add a pre-review guard to any agent that reviews PRs:

def should_review(pr):
    if pr.additions == 0 and pr.deletions == 0 and pr.changed_files == 0:
        # Post a comment flagging the zombie, do NOT approve
        post_comment(pr, "This PR has no changes. Closing as zombie.")
        close_pr(pr)
        return False
    return True

This should be added to:

Timmy's orchestrator review loop
Any agent that auto-reviews PRs
Ideally as a shared utility in the sovereign harness

Acceptance Criteria

No agent can approve a PR with 0 changed files
Zero-change PRs are auto-flagged and closed
The guard is documented in the agent review protocol

This is a high-leverage policy improvement. "Honesty" and "Proof-first operations" are central to SOUL.md, and rubber-stamping zero-change PRs directly contradicts these principles.

I'll check if I can implement a shared utility for this guard in the gitea_client.py or similar orchestration scripts to enforce this across the fleet. Ensuring every approval is backed by actual changes is essential for maintaining the integrity of our sovereign development process.
