All three cited sources were fetched and verified as reachable, on-point, and containing the load-bearing quotes. (1) IRS.gov (PRIMARY) confirms the One Big Beautiful Bill Act enacted all three components as capped, temporary DEDUCTIONS: seniors 65+ "additional deduction of $6,000," "No Tax on Tips" maximum $25,000, and "No Tax on Overtime" maximum "$12,500 ($25,000 for joint filers)"; the quantitative quotes appear verbatim, and the page contains no repeal of Social Security benefit taxation. (2) Tax Foundation (REPUTABLE_SECONDARY) confirms verbatim that OBBBA "does not include this provision [SS-tax elimination], but provides a new additional standard deduction for seniors"; the bracketed clause in the rating is clearly the rater's own gloss, not a claimed quotation. (3) Pacific Life (REPUTABLE_SECONDARY) confirms the title "A Deduction—Not a Repeal" verbatim and explicitly states this "is not a repeal of Social Security taxation." Together the sources support PARTIAL: two of three deliverables (tips, overtime) were achieved through enacted law as capped/temporary deductions rather than blanket exemptions, while the third (SS-benefit taxation) was not repealed as stated but replaced with a separate $6,000 senior deduction. The outcome does not overstate the evidence — it is arguably conservative — and the assigned outcome is PARTIAL, not CHAMPIONED, so no leadership bar applies. Upholding.
