Blueprints
Reference architectures, full operating models for a capability, not a one-off essay. One G.A.I.N subject maps to one playbook series. Governance has two blueprints (operating and runtime) because the audience splits; it is still one G.A.I.N subject.
1. Evaluation: eight planes
| G.A.I.N Evaluation | Principles, ownership, and pillar mapping: published |
| Eval Blueprint | Sources, scorers, modes, gates, eight planes: draft |
Playbooks: Evaluation. Planes: ① Input · ② Data · ③ Context · ④ Reasoning · ⑤ Tool · ⑥ Memory · ⑦ Action · ⑧ Outcome.
2. Agents: intent, orchestration, manifests
Intent at ingress, orchestration in the loop, versioned manifests (pinned tools, schemas only), four autonomy patterns on the route. Model endpoint selection is the LLM Blueprint. PEP is Governance. MCP is transport only.
| G.A.I.N Agents | Principles, policy gate, orchestration: published |
| Agents Blueprint | Intent, orchestration, manifests, Pattern 0-3: draft |
Playbooks: Agents (Plane ① Intent router · Plane ② Orchestration including Memory · Manifests). Patterns: 0 Single inference · 1 Autonomous loop · 2 Deterministic · 3 Guided hybrid.
3. LLM: gateway model routing
| G.A.I.N LLM | Gateway stack principles: published |
| LLM Blueprint | Capability matrix, task routing, canary: draft |
Playbooks: LLM. Handoff from agents: Inference handoff.
4. Governance: operating model and runtime
Two blueprints, one G.A.I.N subject. Operating is the estate control system. Runtime is PGAR on the request path. PGAR gates side effects. It does not own RAG corpora, tool manifests, or the memory store.
| G.A.I.N Governance | Control system: policy, inventory, runtime, evidence: published |
| Governance | Two views, one subject: draft |
| Operating | Four questions, one control system: draft |
| Runtime | SARAC contracts, five boundaries, release gates: draft |
Playbooks: Governance (Operating · Runtime). Boundaries: ① Ingress · ② Agentic app · ③ LLM proposal · ④ PEP + PDP · ⑤ Downstream.
5. Observability: three layers
| G.A.I.N Observability | AI capture path, retention tiers, audit: published |
| Observability Blueprint | Three layers, graph, maturity, reference architecture: published |
Playbooks: Observability.
6. RAG: governed retrieve
| G.A.I.N RAG | Grounded retrieve, validation, attribution: published |
| RAG Blueprint | Mode, scope, PEP pack, validate then synthesize: draft |
Playbooks: RAG. Eval: Context plane.
7. MCP: transport
| G.A.I.N MCP | Tool transport, registry, policy gate: published |
| MCP Blueprint | Gateway, server registry, adapter (not the catalog): draft |
Playbooks: MCP (transport). Tool contracts: Agents: Manifests. Eval: Tool plane.
