 ## Unreleased
 
+- **Breaking:** the `clawhub` and `clawhub-aig` profiles judge skills and plugins with an evidence-only Codex run (`gpt-6.1-sol`) that sees scanner results only. The new profile setting `judge.evidenceOnly` / `overview.evidenceOnly` removes the artifact copy from the command's workspace and refuses `{{ target.files }}`; the profile disables Codex's file, shell, image, web-search and code-execution tools (verified against codex-cli 0.164.0; its sub-agent tools stay offered but inherit the same restrictions). New prompt placeholders `{{ scanner_results }}` and `{{ run_context }}`. `judge.result` keeps the typed fields but no longer carries the Decisions `decision` record. The Decisions API judge remains available through `--judge`.
 - Give scanner commands run against OpenClaw plugin targets a 30-minute budget (was 20 minutes); skill, file and URL targets keep 20 minutes. The judge and overview budgets are unchanged.
 - Refresh Node setup to 7.1.0, use Node 24.22.2 for CI and docs, and Node 26.13.0 for release packaging.
