Vendor Claim Cross-Examination Pack for Support Directors

A pre-renewal interrogation tool for directors of support at 50-500 person B2B SaaS companies managing 3+ external support vendors (BPO desks, AI deflection, automated triage, KB suppliers). The director pastes the vendor's verbatim QBR claim — '38% L1 deflection over Q1', 'AHT reduced 22%', 'CSAT +0.4' — including any footnotes, methodology slides, or caveats. AE's adversarial multi-model debate engine interrogates the claim's internal structure and produces a ranked cross-examination pack: which ticket types are silently excluded, which time window is cherry-picked, which baseline is undefined, which escalations are not counted as failures, which caveats gut the headline number. The 6-pattern autopsy taxonomy maps directly: Temporal & Transmission Blindness flags undefined windows; Concession Laundering flags hedges that nullify the claim; Cosmetic Confidence flags unfalsifiable phrasing. The director walks into QBR with 8-14 specific questions the vendor must answer before any renewal signature, and a graded artefact for CFO defense. AE never sees helpdesk data; the director's own Zendesk pull confirms the structural gap AE predicted.

Support directors face vendors with home-field forensics advantage at renewal time; AE's adversarial debate plus 6-pattern autopsy is uniquely shaped to produce CFO-defensible cross-examination packs at solo-operator scale.
