How to say “Politely address dishonesty” professionally

Level 1: I've reviewed the latest report and noticed a discrepancy in the data presented regarding [specific metric/topic]. Could we schedule a brief discussion to clarify the underlying information and ensure alignment before final submission?

Level 2: Upon cross-referencing the project metrics, it appears there might be a variance in the figures cited for [specific item]. Perhaps we should consolidate our data sources to ensure all stakeholders are operating from a unified and accurate understanding.

Level 3: Regarding the 'optimistic' projections in the Q3 summary, I'm keen to understand how these align with the original SOW and the data points logged in the project management tool. We wouldn't want any 'surprises' when HR audits our performance metrics, would we?

Level 4: The information presented on [specific issue] does not align with the documented facts we have. Moving forward, I need to ensure that all data we present is verifiable to avoid jeopardizing project credibility and team trust.

Level 5: I know what you did.

Level 1: We've cross-referenced the project brief with the recent feedback, and there appears to be a disconnect regarding [specific requirement]. Could we clarify this to ensure our deliverables remain aligned with your expectations?

Level 2: To ensure we are fully compliant with the agreed-upon scope, we've identified a discrepancy between the initial project parameters and some of the recent requests. Let's review the original documentation to re-establish a clear baseline.

Level 3: While we appreciate the 'flexibility' in scope, our records, specifically the signed SOW, indicate a different set of deliverables. We want to avoid any 'misunderstandings' that might impact invoicing or future project phases, naturally.

Level 4: The information you've provided regarding [specific project detail] contradicts our documented agreements and is impacting our ability to proceed effectively. We need to operate on accurate and consistent data to meet our commitments.

Level 5: We have it in writing.

Level 1: I've noticed some inconsistencies between the information you shared regarding [specific task] and what's reflected in the project log. Could we review this together to ensure accuracy?

Level 2: To maintain consistency across our documentation, I wanted to double-check the figures you provided for [item]. My records show a slight divergence, and it's best we align on the definitive data point.

Level 3: Per our agreed-upon sprint commitments, I'm struggling to reconcile your progress update with the actual JIRA tickets closed. Perhaps the 'definition of done' requires a refresher for certain team members?

Level 4: The information you've communicated about [specific deliverable] is inaccurate, and it's directly impacting my ability to complete my part of the project. I need transparent and factual updates moving forward.

Level 5: I saw that.
