SD-142

Analyst position changed materially on hyperjustification literature. Original claim “no published work directly addresses multi-turn sycophancy” refuted by 6 new papers (2025-2026 preprints, EMNLP acceptances). Key papers: Liu et al. (2025) “TRUTH DECAY” (arXiv:2503.11656), Hong et al. (2025) “SYCON Bench” (arXiv:2505.23840). What remains novel: co-constructed bidirectional variant, magnitude-insensitivity, structural counter-measures. Root cause of miss: anchoring on 2022-2023 literature, field moved fast. “The Captain’s challenge was the barometer reading.” Addendum at docs/internal/analyst-hyperjustification-research-2026-02-25.md.
