System Architecture - enterprise-llm-adoption-kit
This document is the system-level architecture attachment for the repository. It keeps the technical stack, runtime boundary, data/control flow, deployment surface, and operating assumptions in one place.

Stack Surface
| Layer | Current surface | Operating note |
|---|---|---|
| Interface | Public demo, README, CLI, package, or static proof surface depending on repository shape | Keep the first screen or command path inspectable without private credentials. |
| Runtime | Python service or lab runtime, Terraform infrastructure modules, Container build surface, Local compose environment, GitHub Actions validation | Keep runtime adapters bounded by environment configuration and documented fallbacks. |
| Control plane | Policies, configuration, job orchestration, tests, and release scripts | Keep operator-impacting changes traceable through docs and validation hooks. |
| Data and artifacts | Fixtures, generated reports, screenshots, exports, logs, or model outputs | Keep sample and generated artifacts clearly separated from private or customer data. |
| Operations | CI, local validation, architecture guard, and handoff notes | Keep the architecture docs current when runtime, data, or deployment boundaries change. |
Cloud Or Local Deployment Boundary
Operating model: stateless runtimes, provider adapters, queue-aware execution, telemetry, and controlled secret boundaries
Deployment patterns
- Infrastructure-as-code entrypoint with explicit variables, outputs, and provider boundaries
- Containerized runtime path suitable for repeatable local, staging, or managed service deployment
- Edge-first deployment model with server-side AI adapters and public-safe secrets handling
- Stateless agent gateway with provider abstraction, retries, usage controls, and trace capture
Control boundaries
- identity boundary and least-privilege service access
- environment separation for local, staging, and managed runtime paths
- secret storage outside source and deterministic fallback for missing credentials
- observability hooks for logs, metrics, traces, and audit events
- rollback path for deployment, schema, and model changes
Resilience controls
- bounded retries with explicit failure states
- health/readiness checks before operator-facing flows are trusted
- idempotent data or artifact writes where repeat execution is possible
- usage and quota guardrails for hosted services and model adapters
AI And Automation Boundary
Operating model: tool calling, retrieval, eval gates, prompt/version control, usage accounting, and deterministic fallback paths
Engineering patterns
- Treat tool calls as typed contracts with retries, timeouts, validation, and trace identifiers
- Evaluate agent behavior with replay fixtures, golden traces, and usage/latency accounting
- Separate deterministic checks from model-generated output so the system remains testable without external credentials
- Capture prompts, inputs, outputs, and decision metadata as inspectable artifacts instead of hidden side effects
- Gate model-assisted actions with policy, confidence, and fallback states before they reach an operator path
Evaluation and model-risk controls
- deterministic fixtures for CI-safe verification
- golden output or schema checks for generated artifacts
- trace capture for prompts, tool calls, inputs, and outputs
- quality gates that fail closed when evidence is missing
Risks to keep explicit
- prompt drift
- tool-call ambiguity
- provider outage
- unbounded latency or spend
