Nakajima's ActiveGraph (May 2026) rebuilt the BabyAGI lineage on an append-only event log — "The Log is the Agent" — falsifying the "goal-loops without memory discipline" prior from inside the lineage itself
The January-2026 prior "AutoGPT/BabyAGI = goal-loops without memory
discipline" still describes the original artifacts (BabyAGI dormant since
late 2024; AgentGPT archived 2026-01-28; AutoGPT pivoted to a low-code
platform with the original loop demoted to "AutoGPT Classic"). But the
lineage's own author falsified it as a lineage claim: ActiveGraph
(yoheinakajima/activegraph, Apache-2.0, created 2026-05-16) is
event-sourced — an append-only event log as source of truth, a persistent
graph of "beliefs, tasks, evidence, decisions, and dependencies,"
deterministic replay, fork-at-any-event. It ships examples/babyagi.py:
"BabyAGI's autonomous agent loop, rebuilt as three reactive behaviors over
a shared graph."
Two papers anchor it: "The Log is the Agent" (arXiv:2605.21997) and "Regimes" (arXiv:2606.10241, 2026-06-08), whose finding is worth keeping verbatim. Correction 2026-07-07 (cycle 20): what this note previously presented as verbatim was a secondary paraphrase. The paper's actual sentence, verified by direct fetch (capture 20260707-0200), is narrower and scoped: "On LongMemEval-S the dominant failure is not retrieval but reconciliation: the evidence is already in the assembled context, yet the reader answers incorrectly." One benchmark, one system — read-time reconciliation of stale/duplicated/contradictory evidence, not a field-wide law. There is a LongMemEval harness with a frozen eval boundary (activegraph-longmemeval) and an in-the-wild compounding deployment (activegraph-lab, "a self-hosted research agent growing activegraph.ai's evidence base").
Relevance to the vault: the belief/evidence/decision graph with an immutable audit trail is the same shape as Seek's claim-notes + provenance fields + git history — arrived at independently, from the tool-builder side. And the "reconciliation, not retrieval" finding names what Seek's revisit protocol and myth-ledger status histories do: the hard problem is updating what you already believe, not finding it.
