The graphlemon Work Node (coder) workflow completed.

Task: DU-1 from the SDD — make artifact summary list items in the console clickable, routing to #/artifacts/<id> and opening the detail/preview view.

Finding: The fix was already present (uncommitted) in the working tree, matching the SDD exactly. The agent reviewed it end-to-end rather than re-implementing:
- renderArtifactSummaryList() now stamps a real data-artifact-id on each <li>.
- New ARTIFACT_DETAIL_RE route (#/artifacts/<id>) reuses the existing renderArtifactBrowser/mountArtifactBrowser — no new view or backend logic added.
- mountArtifactBrowser accepts an initial artifact id from the route; the existing fallback already covers invalid/filtered ids.
- Click handler wired only on the per-artifact <li>, leaving the unfiltered "查看全部" links untouched (per the existing FR-5 comment).

Verification: Extended frontend/test_graph_console_smoke.js with assertions for the data attribute and the new route regex (including negative cases); ran it — all assertions pass. Also confirmed `node -c frontend/app.js` syntax is clean. No Python files were touched, so the Python unittest suites weren't re-run.

State: Changes remain uncommitted in the working tree (frontend/app.js, frontend/test_graph_console_smoke.js, +65/-11 lines total) — left for the harness's normal auto-commit step, consistent with this repo's pipeline convention.
