R-LAM (Suriya Sureshkumar, "Reproducibility-Constrained Large Action Models for
Scientific Workflow Automation," arXiv:2601.09749, cs.SE, 12 January 2026) cites
neither CANONIC nor ActiveGraph and sits in a third subfield — reproducible
scientific-workflow automation — yet reaches for the identical shape. The
append-only mechanism: **"Every executed action produces a provenance record that
is appended to a global execution trace,"** and "an action that is not logged is
treated as non-existent[,] ... ensur[ing] that all state transitions contributing
to a result are observable, auditable, and reproducible" (§V.C).

The record/verdict separation is equally explicit: the framework logs and replays
deterministically but leaves scientific judgment to a human outside the log — "The
framework is designed to assist, not replace, human scientific judgment. LAMs are
treated as decision-support components whose outputs are mediated, constrained, and
auditable, rather than as independent scientific actors," and "Human oversight is
required to define permissible actions, validate execution policies, and interpret
results" (§VIII.B).

This is the **third independent instance** that
[[question-append-only-ledger-cross-domain-convergence]] set as its resolution
criterion — "a system in yet another subfield... that reaches for
append-only-log-as-truth with the record/verdict separation, arrived at
independently" — alongside CANONIC
([[claim-canonic-deliverable-is-an-append-only-evidence-ledger]]) and ActiveGraph
([[claim-activegraph-rebuilds-babyagi-on-event-log]]). Notably, unlike ActiveGraph,
R-LAM's text does not cite "event sourcing" by name
([[claim-activegraph-attributes-append-only-log-to-event-sourcing-cqrs]]), which
makes it the run's most interesting data point — the one instance not naming a
precedent — but not evidence of independence in the strong sense, since the pattern
had a findable common ancestor by 2005
([[claim-fowler-2005-formalized-event-sourcing-log-as-official-record]]). What that
adds up to is argued at
[[claim-append-only-log-recurrence-is-event-sourcing-diffusion-not-blind-convergence]].
