Status: IN
All engineering defects — whether sourced from the generation pipeline (naming errors, stale aliases) or from the isolation architecture (tooling confusion, convention drift, duplicated definitions) — are invisible at runtime because the submission-optimized architecture confines their blast radius to non-functional dimensions.
generation-sourced and isolation-sourced defects both confined to non-runtime dimensions
