Many so-called hallucinations are better understood as upstream structuring failures than as isolated model bugs.
What the phenomenon looks like
The answer invents, blends, or overextends because the source environment left too much room for silent reconstruction: unstable boundaries, missing negations, ambiguous entities, weak hierarchy, or contradictory context.
Why it happens
Treating every failure as a model defect hides the architectural conditions that made the invention likely. The model is still responsible for the output, but the environment often helped determine what kind of invention was easiest to produce.
Why it matters
If the diagnosis remains “the model hallucinated”, remediation will target the symptom rather than the cause. The same drift will then reappear under a slightly different formulation or on a different system.
What must be governed
- Diagnose what the source architecture failed to constrain before treating the event as a pure model bug.
- Look for missing boundaries, unstable entity definitions, and silent hierarchy conflicts.
- Use hallucination cases to improve upstream governability rather than only downstream prompting.
