Why segment-aware imputation
A single global imputer would be wrong for both a 50-person agency and a 5,000-person industrial conglomerate. Segmenting first, then imputing within segment, kept the imputed FTE numbers defensible when stakeholders asked the obvious follow-up: "how did you get this number?"
Why a multi-LLM consensus
Because the imputed values feed an executive-facing agent, a single LLM critique was too noisy. Majority-vote consensus across multiple providers gave a meaningful abstention signal: when models disagreed, the agent surfaced uncertainty instead of fabricating confidence.
