Build complex systems with claims you can inspect.

Requirements, implementation, tests, deployment state, and public claims can drift apart.

Use source-controlled records and automated checks to connect intent, implementation, evidence, and release decisions.

API behavior, validation, persistence, and transport code often diverge across services.

Design typed service boundaries using schema-first models, explicit operations, pluggable engines, and testable ASGI interfaces.

Identity protocols and authorization decisions become difficult to inspect when they are embedded throughout application code.

Model identity flows, policy decisions, credentials, keys, and verification evidence as explicit, testable system boundaries.

AI application code becomes hard to test when providers, prompts, tools, parsing, memory, and evaluation are tightly coupled.

Compose typed model, tool, parser, embedding, vector-store, and workflow components with application-specific evaluation.

Document content, rendering, metadata, accessibility work, and publication evidence are often managed in disconnected tools.

Build source-controlled Markdown and PDF workflows with explicit parsing, rendering, review, and verification stages.

Storage policy, object changes, delivery receipts, and operational evidence are difficult to reconcile after the fact.

Design explicit policy, evidence, delivery, and operator boundaries for storage-related workflows.
