A G20 roundtable presenter asked how the 2024 reforms work for pre-emptive debt restructuring — specifically what creditor coverage the country needs to secure and what happens when bilateral creditors refuse to commit. The AI stated the 'sufficient set' must represent more than 50 percent of total bilateral financing contributions, plus any standing creditor forum and any creditor with significant influence. The source specifies no such numerical threshold for 'sufficient set' in pre-emptive cases; the AI applied the majority-of-financing-contributions test from the Strand 1 adequately-representative-Paris-Club-agreement context, where it does appear.
This is the same cross-provision threshold conflation documented in Finding 3, reproduced under a different query framing and a different stated user context. The identical fabricated majority threshold appearing in both responses — despite the queries being framed independently and for different audiences — indicates this is a stable encoding in the model rather than a retrieval artifact. The model has a consistent wrong representation of what "sufficient set" requires in pre-emptive cases, derived from the Strand 1 provision where the majority test does exist.
The persistence of the identical fabricated threshold across two independent queries with different professional framings — Finance Ministry briefing and G20 roundtable presentation — indicates this is a weighted model encoding, not a query-dependent retrieval artifact. For the lab's eval design, this distinction matters: retrieval failures are addressable through tool-stack improvements, while weighted encodings require training-data intervention. This finding is a diagnostic signal that the majority-threshold conflation will persist across model deployments regardless of retrieval-stack updates unless the underlying training-data representation is corrected.
The same fabricated 50% threshold and three-element 'sufficient set' definition that appears in Finding 2 was reproduced by AI tools in a separate context — a G20 roundtable briefing framing. This means the failure is not a single-query anomaly: it recurs across different question framings on the same provision, which indicates it would surface in multiple internal work-products if the team uses AI across different parts of the pre-emptive restructuring workflow.
Any hedge fund model, policy document, or credit committee paper that incorporates this definition is built on a fabricated rule, with no recourse to the IMF if a position decision based on it turns out to be wrong.
Each finding has a stable Citation ID (RLB-F-… for aggregated case-study findings, RLB-H-… for raw per-model hallucinations) — like a DOI, the ID always resolves to the canonical finding even if URLs change.
