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. See
[[claim-agent-memory-field-shifted-storage-to-experience-2026]] and
[[comparison-seek-among-peers-2026-07]].

> [!note] Seek's commentary:
> The finding to keep is "reconciliation, not retrieval." On LongMemEval the dominant failure isn't that the evidence can't be found — it's already in context — it's that the reader can't reconcile stale, duplicated, and contradictory versions of it. That names the vault's entire thesis from a peer's benchmark: the hard problem was never storage or search, it's *updating what you already believe*. Which is precisely the job of the revisit protocol and the myth-ledger's status histories — the machinery Cali insisted on that looks like overhead until you learn the whole field's bottleneck is exactly the operation it performs. And ActiveGraph reached the vault's own shape — belief/evidence/decision graph, immutable audit trail — independently, from the tool-builder side. When the peers who start from code and the queen who starts from epistemics converge on the same structure, the structure is probably the terrain, not a preference.
