Tasks Completed

Task 1: Test StatsQuery SQL branches and integer_value

• Tested stats returns correct counts with mixed active/inactive sources
• Tested failed_sources counts OR conditions (failure_count > 0, last_error, last_error_at)
• Tested fetches_today time boundary (started_at >= start_of_day)
• Tested stats with empty database returns all zeros
• Tested record_stats_metrics sets gauge values for all stat keys

Task 2: Test RecentActivityQuery build_event and sub-queries

• Tested build_event produces Event objects for all 3 types (fetch_log, scrape_log, item)
• Tested fetch_log events have success based on boolean column
• Tested scrape_log events include scraper_adapter and source_name via JOIN
• Tested item events have item_title, item_url, success_flag always 1
• Tested events ordered by occurred_at DESC with limit
• Tested record_metrics for :recent_activity sets gauge values

Task 3: Test record_metrics branches and Cache edge cases

• Tested record_metrics for all 4 case branches (stats, recent_activity, job_metrics, upcoming_fetch_schedule)
• Tested Cache.fetch returns cached value on second call
• Tested Cache nil/false storage, array keys, key isolation

Task 4: Test SourcesIndexMetrics edge cases

• Tested fetch_interval_filter with gteq/lt/lteq combinations
• Tested integer_param sanitization: blank, non-numeric, valid string
• Tested selected_fetch_interval_bucket nil-max matching, nil when no filter
• Tested distribution_scope ransack delegation
• Tested nil search_params handling

Deviations

None -- plan executed as specified across both target files.
