AI agents have a state-integrity problem, not a memory problem: one developer's State Ledger experiment
thefeelgoodconductor · reddit · 2026-09-16
A developer building a long-running, model-agnostic AI system kept hitting failures that looked like memory problems but weren't: the agent correctly recalled facts from weeks ago that were simply no longer true. Retrieval worked; the issue was treating stored facts as current state. He proposes distinguishing MEMORY (what happened) from STATE (what is currently believed) and PROVENANCE (why it's believed), representing change explicitly as a chain of OBSERVATION → INTERPRETATION → HYPOTHESIS → EXPERIMENT → OUTCOME → STATE CHANGE, tagging claims with provenance levels (verbatim/context/derived/unknown), and linking decisions via supersedes/contradicts/derivedfrom/validatedby so history is preserved rather than deleted. He also flags a subtler failure: inference itself becoming memory — an agent stores an inferred pattern and later retrieves it as an original fact. The experiment is called a State Ledger.
