Kanban completed-run metadata renders as alarming large highlighted box

[novaflash82]

Bug Description

Completed Kanban jobs in the dashboard/TUI render their run metadata/diff output as a large pale highlighted box. The box looks visually alarming and reads like an error/crash panel even though the job completed successfully.

This appears to be a UI/UX rendering issue rather than a task execution failure: completed runs are working, but the completed-run metadata/output preview is shown too prominently and with poor contrast.

Steps to Reproduce

1. Create and run a Kanban task that writes a file and completes with metadata, e.g. changed_files, source URLs, and/or a generated Markdown artifact.
2. Open the Kanban dashboard/TUI task detail view for the completed task.
3. Scroll to the RUN HISTORY section.
4. Observe the completed run summary and metadata/file preview panel.

Expected Behavior

Completed jobs should look clearly completed and non-alarming. Large metadata/diff blobs should probably be collapsed by default or labeled clearly, e.g.:

• Run metadata collapsed/expandable
• Changed files list shown compactly
• Diff / artifact preview behind an explicit expand control
• Better contrast so the panel does not look like an error state

Actual Behavior

The completed run shows a large, pale highlighted box containing JSON-ish metadata and/or file preview content. In practice it looks like a bug, warning, or crash output even when the task completed normally.

Example Context

Observed on a completed Kanban writer task. The run history showed:

• COMPLETED @WRITER
• A normal success summary
• A large highlighted block containing metadata such as changed_files, URLs, homepage sections, and generated artifact details

The task itself completed successfully; the problem is the presentation of the completed-run output/metadata.

Suggested Fix

Treat completed-run metadata and inline diff/file previews as secondary details:

1. Collapse metadata by default in completed run history.
2. Add an explicit label like Run metadata or Output preview.
3. Render changed files as a compact list.
4. Use a less alarming background/contrast treatment.
5. If possible, show only the summary by default and require expansion for full JSON/diff content.

Environment

• Hermes Agent Kanban dashboard/TUI
• OS: WSL/Linux
• Provider/model used by worker: openai-codex / gpt-5.5

Resolved. PR #19980 landed via salvage PR #20448 (rebase-merge). The completed-run metadata panel is now visually toned down — the alarming large highlighted box is gone.
