What Pharn Regress does

description: "Detect regressions OUTSIDE the just-built feature in the USER's codebase — the fifth product-pipeline stage (spec → plan → grill → build → regress → verify → ship). Re-run the project's existing deterministic suite (its tests / type-check / lint) over the area OUTSIDE the feature's declared scope at the pre-build BASELINE and at HEAD, and flag any gate that flipped pass→fail. The verdict is a deterministic exit-code comparison (pharn/floor/check-regress.mjs) — ZERO LLM-judge in
