# Ingestion engineering principles Load only the references needed for the task: | When the task involves | Read | | --- | --- | | Repository purpose, pipeline boundaries, sources, chunking, jobs, or Search | [Ingestion architecture](references/ingestion-architecture.md) | | Python design, async behavior, modules, or maintainability | [Python implementation](references/python-implementation.md) | | Tests, validation, compatibility, or evidence | [Testing and evidence](references/testing-and-evidence.md) | | Identity, ACLs, secrets, source data, audit, or operations | [Security, data, and operations](references/security-data-operations.md) | Use these principles as design questions, not dogma. Task requirements, executable configuration, versioned contracts, and current behavior remain the sources of truth.
