 The output is Markdown and can be pasted into a PR's AI Assistance or Merge Decision notes.
 
+For a shorter PR-page comment format, use:

+The default CLI format is intentionally detailed. The GitHub comment format is optimized for maintainer scanning: the visible summary is bilingual, while detailed file lists, local commands, and hold conditions are kept in collapsible sections.

@@ -29,16 +37,18 @@ DeePTB has two advisory workflows for this plan:
 
 The comment workflow is designed for fork PRs. It checks out the trusted base commit from the main repository, reads changed file names through the GitHub API, then runs the base-branch copy of `scripts/ci/pr_review_plan.py`. It must not checkout or execute code from the fork branch.
 
+The comment workflow may also add an Evidence section based on GitHub check status. That evidence is owned by the workflow, not by `pr_review_plan.py`, because the script only knows changed file names.
+
 Required permissions for the comment workflow are intentionally narrow:
 
 ```yaml
 permissions:
   contents: read
-  pull-requests: read
+  pull-requests: write
   issues: write
 ```
 
-`issues: write` is needed because PR timeline comments use the issues comments API. The workflow updates the existing bot comment using a hidden marker instead of creating a new comment on every PR update.
