How to say “Politely refer to fabrication” professionally

Level 1: Thank you for sharing this update. I'd like to cross-reference a few points with the original project specifications/data we have on record to ensure alignment before we proceed.

Level 2: I appreciate you bringing this forward. To ensure full transparency and accuracy for all stakeholders, perhaps we could revisit the source documentation together to confirm the foundational details?

Level 3: That's certainly an… *interesting* interpretation of the Q4 metrics. Before we finalize the executive summary, could we perhaps review the original data sets, as outlined in the Data Governance Policy v3.1, to ensure our narrative remains anchored in verifiable truth?

Level 4: I need to address this directly. The information presented diverges significantly from our documented facts, and proceeding with it could compromise project credibility and future outcomes.

Level 5: No, that's a lie.

Level 1: We appreciate your comprehensive overview. To ensure our understanding is fully aligned, could we collaboratively review the specific data points referenced against our agreed-upon deliverables and baseline documentation?

Level 2: Thank you for highlighting your perspective. In order to move forward with complete clarity and validate our approach, it would be beneficial to reconcile these points with the original scope and project metrics we established.

Level 3: We've certainly noted your *creative interpretation* of the project's trajectory. As per the mutually signed Statement of Work, Appendix B, and all subsequent change requests, the deliverable was X, not Y. We just want to ensure our billing remains aligned with reality, not aspirational revisionism.

Level 4: With respect, the information you've presented regarding [specific point] is not consistent with our records or the terms outlined in our agreement, and we need to clarify this before proceeding.

Level 5: That's not what we agreed on.

Level 1: Thanks for sharing your perspective. I recall the data points differently; perhaps we can review the source material together to ensure we're both operating from the same information base?

Level 2: I understand your interpretation. For the sake of consistency across the team, it might be beneficial to re-examine the original findings, especially regarding [specific point], to maintain a unified factual foundation.

Level 3: That's a bold re-imagining of the project history. As per our shared Slack channel archives and the project's 'Single Source of Truth' document, [specific fact] was actually [actual fact]. Just ensuring we're all aligned, as the sprint retrospective guidelines demand.

Level 4: I need to correct this. The information you've presented is not consistent with the facts we have established, and this could mislead others on the team.

Level 5: That never happened.
