"description":"Schema for per-dimension port-analysis reviewer findings. Used by the large-port-pipeline source analysis review (Phase B1.5). The port source-analysis pipeline uses a deliberate three-value severity contract — BLOCKER / MAJOR / MINOR — and never emits INFO (matching implement/reference/large-port-pipeline.md and source-analysis.md, which name only those three). This is a documented exception to the canonical four-value set (BLOCKER / MAJOR / MINOR / INFO) in reviewer-output.schema.json and synthesis.schema.json.",
