Summary

The bottom logs sheet used to grow past its snap height: long messages stretched the panel, expanded JSON had no horizontal bound, and the search box only updated the URL. Operators now get a diagnostics console that stays inside the drawer (and the full Logs Viewer page), with search actually querying Loki.

Latest entries are listed first. The list follows new entries only while you are already at the top; scrolling down or expanding a row keeps your place, with a Jump to latest control when you leave the head. Collapsed HTTP rows show method, path, status, and duration so you can scan without opening every line. Loki failures surface as retryable errors instead of a silent empty list. The drawer no longer writes filter params onto module routes; only /logs-viewer syncs the URL.

Test plan

• Open Logs from a module page. At 50%, 75%, and near-full snap points, only the log list scrolls.
• Confirm the newest log is at the top of the list.
• Expand a row with nested JSON and a very long message; the page should not grow horizontally.
• Scan a collapsed HTTP row for method, path, and status without expanding it.
• Search for a substring and confirm Loki results change (not just the URL).
• Toggle Live, scroll down, then confirm the stream does not yank you to the latest entry until Jump to latest (scrolls to top).
• Refresh with Loki down (or a forced error) and use Retry.
• Open /logs-viewer, apply filters, reload, and confirm the query string is restored.
• Close the drawer with Escape and check light/dark.

pnpm lint (0 errors on these files), pnpm test:logs-viewer, and pnpm build passed. Authenticated click-through of the live drawer was not completed from this session.

Targets ui-rewrite so this stays on the current admin rewrite rather than main.
