+
+Failed or unavailable checks:
+
+- None of the recorded final-candidate checks failed or were unavailable.
+  Dependabot PR #2's failed run remains separate negative evidence for that PR,
+  not replacement evidence for PR #9. An earlier intentional offline actionlint
+  probe in a fresh detached worktree failed closed before the verified cache was
+  populated; it is not final-candidate validation evidence.
+
+Remote evidence:
+
+- Private PR #9's credential-free initial code-bearing CI run 29907523251 passed
+  quality, Python 3.10 through 3.14, minimum OpenAI, package, exact-artifact
+  clean install, retained artifact digest, and copied-checkout jobs. The PR-only
+  latest-within-major canary skipped as designed; scheduled or Dependabot
+  execution remains unverified.
+- The canonical repository was confirmed private after the successful
+  replacement run. No visibility, secret, environment, or
+  repository-protection change was made.
+
+Live evidence:
+
+- The live-smoke path was not executed, and no live API request was made.
+  Transport success and provider behavior therefore remain unverified.
+
+Registry and release evidence:
+
+- Release Please, immutable-release publishing, PyPI OIDC, provenance, and
+  public-registry installation were not executed. No tag, release, or
+  publication was created.
