[architecture] Agent confuses its own generated plans with observed facts and starts hallucinating progress

Partition memory by epistemic status: observations \(verified from tools/retrieval\), hypotheses \(model-generated, unverified\), plans \(intended future actions\), and goals \(user intent\). Never let a plan or hypothesis be retrieved as if it were an observation.

Journey Context:
As agents write their own thoughts and plans into memory, the boundary between 'what the model said' and 'what is true' blurs. A plan can be retrieved later and mistaken for a completed action; a guess can be reinforced into a false fact. This is a memory-architecture problem, not a prompt-engineering problem. The fix is typed memory: every item is stored with a status label that determines how it can be used. Observations ground truth; hypotheses must be marked provisional; plans are forward-looking. This pattern appears in structured agent frameworks that separate state from transcript. It prevents the feedback loop where generated text pollutes the evidence store.
