An LLM operating in different environments produces different answers because ambient context reshapes how questions are interpreted before retrieval begins

AI Summary

•The author identified two distinct retrieval mechanisms across environments: Ambient Frame Retrieval Bias (where pre-loaded context reinterprets incoming questions before retrieval) and Premature Retrieval Closure (where retrieval stops once the first answer arrives, even if dimensionally incomplete).
•When the same model answered a question about a technical concept called Phantom Resolution in two differently-configured environments, one provided structural answers while the other surfaced causal and narrative context—not because of architectural differences in the Transformer (attention mechanism and weights were identical), but because the environments pre-loaded different memory files and protocols.
•The mismatch between system output and operator need is not a failure—the structural answer was correct—but a dimensional incompleteness: the author's comprehension is narrative and causal, while one environment's dense dependency tables and tool registries reframed the question into purely structural terms, terminating retrieval before narrative sources were consulted.
