# Which issue does this PR close? Closes #. # Rationale for this change The `tpch_plan_stability` suite in `ballista-scheduler` compares the distributed physical plans for the 22 TPC-H queries against approved golden files. When a change intentionally alters distributed planning, the suite fails with a plan-drift diff and the goldens must be regenerated. This workflow was not documented anywhere in the contributor guide, so a contributor hitting the failure has no pointer to `dev/update-tpch-plan-stability.sh` or an explanation of what the goldens represent. # What changes are included in this PR? Add a "TPC-H plan-stability golden files" subsection to the contributor development guide (`docs/source/contributors-guide/development.md`). It explains what the golden plans capture (stage boundaries, shuffles, exchange reuse), that they are planned deterministically against a synthetic statistics-only table so no TPC-H data or running cluster is needed, where the approved files live, and how to regenerate and review them with `dev/update-tpch-plan-stability.sh`. Docs-only change. `npx [email protected]` reports no formatting changes. # Are there any user-facing changes? No. Documentation only; no code, API, or behavior changes. -- This is an automated message from the Apache Git Service.
