Do not infer a\nverdict from source inspection alone.\n\n## Preconditions\n\n- Require a reproduction that runs on the reported version and has a precise\n  expected-versus-actual observation.\n- If that prerequisite is missing or unreliable, stop and report the blocker.\n  Do not replace it with a different reproduction.\n\n## Workflow\n\n1. Preserve the reproduction code, configuration, runtime, commands, and inputs.\n2. Run both versions in equivalent disposable, least-privilege environments\n   with no credentials, SSH agent, sensitive host mounts, or unrelated user\n   data. If adequate isolation is unavailable, report the blocker.\n3. Resolve and record the exact reported Next.js version and exact published\n   `next@canary` version.\n4. Run the reproduction on the reported version and confirm the prerequisite\n   observation. If it no longer matches, return `inconclusive`.\n5. Run an isolated copy on canary.
