R2 — source-grounded structural comparison with LangGraph 1.2.11

LangGraph 1.2.11 (checkpoint 4.2.0, checkpoint-sqlite 3.1.1) could not be installed — outbound PyPI DNS was unavailable — so the round pins public release/source contracts and compares them with AER-0's executable invariants. Runtime-owned persistent state, checkpoint history, version tracking, long-term stores and TTL memory all converge (LangGraph is richer on resume, time travel, concurrency and delta checkpointing). What remains AER-default-distinct: candidate → verify → commit, mandatory fact provenance, node-level optimistic epistemic commit, task-conditioned tension refresh, capability/container separation, explicit epistemic-operator routing, and the graph meaning an epistemic world representation rather than control flow.

Research status: STABLE the current conclusions are relatively stable
Evidence level: E2 Controlled experiment
Result: MIXED
Data basis: DETERMINISTIC RUNTIME A deterministic scenario executed in a real runtime; the code and procedure are listed, and the numbers are what they are.

Hypothesis

hypothesis: Against a real stateful agent runtime, some AER semantics remain distinct beyond 'external state outside the model'.

Setup

software_environment: Python 3.11+, SQLite; no network, no external database, no LLM API required.

Procedure

procedure: Pin LangGraph release 1.2.11 at commit 644815f (checkpoint base, PregelProtocol, BaseStore, Agent Protocol docs); classify each axis; keep AER invariants covered by the local suite.

Interpretation

interpretation: The candidate AER core after R2 is epistemic world-state semantics + candidate/verify/commit authority + mandatory fact provenance + node-local tension refresh + capability/container separation + explicit epistemic-operator routing — a major compression of the whitepaper. Everything else is a recurring engineering form.

Limitations

limitations: Cross-runtime performance, trace and operational equivalence NOT MEASURED; AER side executable, LangGraph side documentary.
AER-0 is not a 'more advanced runtime' on the available evidence.
