Anti-patterns

Domain / step

• I/O and storage APIs in the processor
• prometheus_client / Grafana JSON in the step
• Homegrown embed/cluster math
• Custom Streamlit UI
• Parsing YAML manifests

Framework

• storage → processing|telemetry
• DTOs in telemetry instead of contracts/
• if backend == / if mode == instead of registries
• Domain column defaults (doc_id) in storage/feed
• Import-only shim files
• Dual-write datasets
• Runtime CREATE TABLE
• Committing *_generated_dashboard.json
• Duplicating the train group-loop in every embed backend

Params

• Framework reading domain.*
• UI control with no reader
• Literal fallback ≠ DRTML default
