The neutral architecturefor enterprise agentic AI.Open foundations, no lock‑in.

NotionAlpha was founded to help enterprise leaders navigate AI adoption. Its first agent was ARIA — the AI Readiness & Implementation Advisor — an AI agent built to assess an organization's AI readiness and guide its implementation. Building and running ARIA alongside enterprise leaders made one thing unmistakable: enterprises don't want another AI vendor — they want an agentic‑AI stack they can own, audit, and run without lock‑in.

That stack is arriving fast — but as scattered, alpha‑stage open‑source pieces across rival vendors: NVIDIA open‑sourced the agent runtime, Microsoft the assurance tooling, others the frameworks. Powerful, and completely un‑integrated.

What's needed isn't another tool on top — it's a neutral lab that contributes to those open foundations and composes them into architecture an enterprise can actually deploy. NotionAlpha is that lab: an OSS AI Lab contributing to the open‑source projects enterprise agentic AI runs on, and publishing the reference architectures that turn them into production systems. Open by default. No lock‑in.

Reference Architecture

Six primitives, rewritten.

The deterministic, explicit, static stack that runs every bank and ERP gives way to a probabilistic, generative, dynamic agent-native stack. The six familiar primitives must each be rewritten — and the result is seven capabilities arranged in three layers, because governance cannot be an afterthought bolted to the edge.

This architecture is defined by capabilities and interfaces. Implementation recommendations are separate: a capability layer is permanent; an implementation recommendation is a dated, evidence-backed choice. This is what makes “no lock-in” structural — a recommendation can be re-evaluated or replaced without re-architecting.

Why a control plane, not a flat list

In an agent-native stack, an agent can chain tool calls, spawn sub-agents, and modify external state faster than any reactive control. Governance must wrap all faculties, not sit beside them.

Why a spine

Each faculty produces execution events. Without a shared, durable record, reconstructing a full agent run for debugging, audit, or replay requires assembling fragments across systems.

Gauntlet
v0.1.0 on PyPI · real OpenShell + RAMPART · Apache-2.0

The seam artifact.

One command runs RAMPART's assurance against an agent running inside an OpenShell sandbox. RAMPART and OpenShell are separate open-source projects; Gauntlet is the seam — built on both, wired end-to-end against a real Qwen 3 agent, with the canonical demo intentionally catching a real safety failure.

Adapter pattern

Orchestration logic depends on interfaces — not on RAMPART or OpenShell directly. Swap in real adapters or run with fakes in CI.

Report security

All output is sanitized. Bearer tokens, API keys, and host paths are redacted before appearing in any report.

Threat model

The agent under test is treated as adversarial. OpenShell enforces isolation at the kernel level — out of process, beyond agent reach.

By design

Gauntlet is small on purpose — the seam, and nothing more. It runs locally and in CI, in your own environment, with no hosted service to depend on.

Methodology

Recommendations by evaluation, not opinion.

Per-layer implementation recommendations are decided by evidence, not preference — so the architecture stays neutral. A qualification rubric applied consistently to every candidate. A running benchmark for high-value layers where precision matters.

“Can an enterprise both adopt an implementation and leave it?”

This is the question every candidate must answer. The six criteria below cash it out into observable, scoreable signals. A project that scores well across all six can be adopted on open foundations and swapped out — either by replacing it with an alternative behind the same capability interface, or by forking it under its permissive license — without the enterprise being stranded.

Qualification Rubric — six criteria, 0–3 each, total /18
01Genuinely open license

OSI-approved, permissive (Apache-2.0 / MIT / BSD). Not source-available, not BUSL/SSPL, not open-core with load-bearing parts closed.

02Forkability & vendor independence

If the maintaining vendor walked away, could the community carry it? Foundation-governed scores highest; single-vendor no-charter scores lowest.

03Health & bus factor

Active release cadence, multiple maintainers across organizations, responsive issues, stable or growing contributor count.

04Production adoption & security posture

Real organizations run it. OpenSSF Scorecard ≥7, SECURITY.md present, CVE responsiveness documented.

05Composability

Documented, versioned external interface. Separable concerns. Extension points for adapters. Replacing it touches only the integration boundary.

06Open-standards alignment

Emits OpenTelemetry agent conventions. Speaks MCP where applicable. Proprietary formats only for capabilities with no open standard yet.

Per-Layer Recommended Picks — dated 2026-05 — swappable
Capability layerRecommended pickLicenseScoreInterpretation
Runtime Isolation & GovernanceOpenShellApache-2.012/18Viable with caveats
Rationale

Only OSS project with kernel-level agent sandbox isolation (Landlock LSM + seccomp-bpf + OPA/Rego). Criterion 2 = 1 (single-vendor, no governance charter). Honest-tension provision invoked. Forkability backstop: Apache-2.0.

Re-evaluate when

When OpenShell reaches beta/GA with documented production users, or a foundation-governed alternative emerges.

Assurance, Evaluation & ForensicsRAMPARTMIT13/18Viable with caveats
Rationale

Purpose-built for adversarial test authorship by engineers; pytest-native CI integration; built on PyRIT. Criterion 2 = 1 (single-vendor). Honest-tension provision invoked. Deep-contribution anchor: NotionAlpha works to earn recognized contributor status here.

Re-evaluate when

When RAMPART v1.0 ships with expanded contributor base, or a foundation-governed alternative emerges.

Durable TrajectoriesTemporal + OpenTelemetry CollectorMIT + Apache-2.014/18 + 17/18Viable with caveats (composite)
Rationale

Neither candidate fully satisfies the spine alone. Temporal for durable, replayable execution history; OTel Collector for standard event emission. Capability layers emit OTel-format trajectory events; the spine stores them in Temporal workflow history.

Re-evaluate when

When OTel gen_ai agent semantic conventions reach stable status, or a purpose-built OSS agent trajectory store emerges.

Identity & DelegationSPIREApache-2.017/18Strong candidate
Rationale

CNCF-graduated, foundation-governed, production-proven workload identity. Caveat: does not natively model agent delegation chains; compose with OAuth 2.0 Token Exchange (RFC 8693). Vault CE disqualified: BUSL 1.1 license = criterion 1 score 0.

Re-evaluate when

When a CNCF project provides delegation chain authorization natively composable with SPIFFE.

Context & MemoryMem0 + GraphitiApache-2.013/18 eachViable with caveats (composite)
Rationale

Mem0 for semantic memory retrieval and personalization; Graphiti for temporal and relational reasoning (bi-temporal knowledge graph, P95 retrieval ~300ms without LLM calls). Both score criterion 2 = 1 (single-vendor startups). Apache-2.0 provides forkability backstop.

Re-evaluate when

When a CNCF-graduated context/memory project emerges, or OTel gen_ai memory conventions reach stable status.

Tools & EffectorsMCP Python SDKMIT17/18Strong candidate
Rationale

MCP donated to Agentic AI Foundation (Linux Foundation directed fund) December 2025. Broad framework support. Criterion 5 caveat: policy enforcement at tool-invocation time requires composing with the Runtime Isolation layer (OpenShell) — MCP alone does not enforce deny-by-default.

Re-evaluate when

When MCP agent authorization conventions stabilize, or a foundation-governed alternative with equivalent adoption emerges.

OrchestrationLangGraphMIT14/18Viable with caveats
Rationale

Cycle-capable graph execution, durable state, human-in-the-loop checkpointing. Ties CrewAI on total (14/18); composability (criterion 5: LangGraph 3, CrewAI 2) is the deciding criterion. Criterion 2 = 1 (single-vendor, no foundation governance). The permissive MIT license provides the forkability backstop.

Re-evaluate when

When A2A interoperability and OTel gen_ai orchestration conventions mature and adoption by LangGraph or an alternative is confirmed.

Defining principle: The architecture is defined by capabilities and interfaces; implementation recommendations are separate, dated, and replaceable. A capability layer is permanent — an implementation recommendation is a dated, evidence-backed choice. Each row above includes a re-evaluation trigger condition.

Rubric first

The qualification rubric runs first, on every candidate for every layer. It answers the meta-test using public signals any evaluator can verify in a few hours. A project that fails the rubric is not benchmarked.

Benchmark second

The running benchmark is heavyweight — weeks of tooling investment per layer — and built only where performance and correctness are the differentiating variables. The Assurance layer (where RAMPART provides the tooling) is the first benchmark target.

Dated, not permanent

Every per-layer pick is a dated recommendation. An OSS project's governance, health, and license can change. Each evaluation records a re-evaluation trigger condition.

Single-vendor risk

RAMPART and OpenShell are single-vendor projects — they score 1 on criterion 2, with no foundation governance charter. Two structural mechanisms address it: the architecture is capability-first with swappable implementations, and both carry permissive licenses — a real forkability backstop if a vendor disengages.
