From 9472dd8fbe532718be277cdee01483d690e55c4c Mon Sep 17 00:00:00 2001 From: StreamKit Devin Date: Sun, 22 Mar 2026 21:02:21 +0000 Subject: [PATCH 01/10] feat: add log viewer/inspector to admin UI Add a new log viewer in the admin section with: - Backend API: GET /api/v1/logs for paginated log reading with byte-offset paging, direction (forward/backward), and level+text filtering. GET /api/v1/logs/stream SSE endpoint for live tail. - Frontend: LogsView component with filter bar (text search + level dropdown), pagination (Older/Newer/Latest), and live tail toggle with auto-scroll. - Admin-only access via access_all_sessions permission. - E2E tests covering navigation, filtering, pagination, and API responses.
