 The Boatstack repository receives product/runtime changes through a generated pull request. Review the PR's `UPSTREAM.json`, tests, adapter diff, and context-size change; do not hand-edit generated output on `main`. `.github/workflows` is the exception: it is Boatstack's executable control plane, excluded from scheduled projection and changed only through a separate manually reviewed Boatstack PR.

 The evidence supports specific failure mechanisms and guardrails. It does not establish that Boatstack is optimal, that control-theory notation proves software quality, or that one workflow dominates every team. Those are evaluation questions, so the distribution preserves measurements, provenance, gaps, and negative results.

+### Rejections name the values you can use
+
+Two errors told you what was wrong but not how to fix it, so you had to discover the answer out of
+band. When the bounded planning writer rejected an artifact name, it echoed the name you gave but not
+the names it accepts. The accepted names are filenames that end in `.md`, so the natural guess, such as
+`plan`, is always wrong. When an approval no longer matched the plan, the error said the fingerprint did
+not match but did not say what the current fingerprint is.
+
+Both now carry the answer. The planning writer lists the accepted artifact names and notes the `.md`
+suffix, so `plan.md`, `source-plan.md`, and the rest are visible at the point of rejection. The approval
+error reports the plan's current fingerprint and points at check-plan to confirm it, so you can
+re-approve against the right value without a separate lookup.
