Phase 21.01 – Log Consolidation Notes (2025-10-15)

Existing UI Inventory

• app/views/source_monitor/fetch_logs/index.html.erb
  • Columns: Started timestamp, Source link, HTTP status, Result badge, item delta summary, view link.
  • Page-level filter: status (All, Successes, Failures).
  • Metadata surfaced via badges and counts; table limited to 50 rows.
• app/views/source_monitor/fetch_logs/show.html.erb
  • Summary stack with source, HTTP, success flag, duration, item counts, timestamps, job id.
  • Secondary panels for error details (message, backtrace), HTTP headers (pretty JSON), metadata.
• app/views/source_monitor/scrape_logs/index.html.erb
  • Columns: Started timestamp, Item link, Source link, Result badge, duration, view link.
  • Same status filter bar; duration replaces item delta metrics.
• app/views/source_monitor/scrape_logs/show.html.erb
  • Summary with item/source links, adapter, HTTP, success flag, duration, content length, timestamps.
  • Panels for error details and metadata.
• Navigation (app/views/layouts/source_monitor/application.html.erb) now surfaces a single Logs entry pointing at the consolidated index.

Combined Layout Outline

• Single "Logs" index with shared table:
  • Columns: Started, Type badge, Subject (item or source), Source link, HTTP/adapter summary, Result badge with inline error text, Metrics (fetch deltas or scrape duration), Detail link.
  • Rows expose data-log-row identifiers (fetch-<id> / scrape-<id>) for tests and Turbo.
• Unified filter bar:
  • Status toggle (All/Successes/Failures) and Log Type toggle (All Logs/Fetch Logs/Scrape Logs).
  • Search form includes free-text box, timeframe select (24h/7d/30d), explicit start range inputs, and numeric source_id/item_id filters.
  • Pagination uses SourceMonitor::Pagination::Paginator with Prev/Next links and a page indicator span.
• Detail views remain type-specific (fetch/scrape) but back links now route through source_monitor.logs_path with the appropriate log_type preset.
• Controller composes SourceMonitor::Logs::Query + TablePresenter; no shared concern is needed.
