Finding people from a natural-language description (``ML engineers transitioning to research roles in biotech'') is increasingly delegated to LLM agents and framed as information retrieval. We argue that it is fundamentally a requirements engineering task: such a request is an under-determined requirement with implicit constraints, many valid answers, and no acceptance criterion, so useful answers require eliciting, validating, and verifying the requirement before search can matter. We present \sys{}, to our knowledge the first interactive, requirements-driven candidate-sourcing agent (it elicits, validates, retrieves, and verifies a vague people-request into a justified slate through bounded elicitation, workflow templates, a two-stage commit protocol, and bidirectional termination guards) and \bench{}, a benchmark that runs the requirements lifecycle (criteria-anchored validation, multi-model evidence-grounded oracle construction, and cost-aware verification). Across $21$ systems and all $691$ requirements, \sys{} dominates breadth ($100%$ coverage at $2.5\times$ the yield) and is \emph{near-orthogonal} to the field, with $90%$ of the people it returns are surfaced by \emph{none} of $20$ strong LLM-plus-web baselines combined. Beyond breadth, an evidence-grounded judging of every system shows \sys{} \emph{recalls} the most relevant real people: $0.241$ of the union pool, $1.9\times$ the next system, with a bootstrap $95%$ interval disjoint from every baseline. \sys{} is thus the strongest \emph{sourcing} engine (the deepest real, reachable candidate pool), while precision-ranking LLMs serve as~complementary verifiers.

Consistency verification of drilling reports is critical for engineering quality control because a single data item may be distributed across reports with different formats, units, and page structures. Existing retrieval-augmented generation methods remain sensitive to retrieval and parsing errors in such documents, whereas ultra-large models impose substantial local computing and memory costs. This study proposes a lightweight tool-augmented framework based on dual-teacher distillation and sparse mixture-of-experts (MoE) modeling. Qwen3-235B-A22B serves as the primary teacher and Qwen3-30B-A3B as the assistant teacher. Their tool-use and task-planning capabilities are transferred to a sparse MoE student upgraded from a Qwen3-1.7B dense backbone through trajectory pruning, sample decomposition, and token-level Kullback–Leibler (KL) distillation. The student adopts an eight-expert Top-2 routing architecture. Experiments on 1000 drilling reports containing 30,127 verification instances show an F1 score of 58.0 ± 0.5%, with file-level, location-level, and exact-match accuracies of 66.5%, 55.2%, and 45.0%, respectively. The model contains 9.1B total parameters and 2.8B activated parameters, and reaches a latency of 12.1 ms per forward pass and a memory footprint of 18.4 GB under bfloat16 (BF16) precision. The reported F1 score characterizes the end-to-end verification task rather than an autonomous safety decision capability. The framework is intended to support evidence localization, anomaly prioritization, and expert review in local deployment settings.
