Tasks Completed

Task 1: Test BulkSourceScraper disabled and invalid selection paths

• Tested scraping_enabled: false returns error result with failure_details
• Tested Result struct methods: success?, partial?, error?, rate_limited?
• Tested normalize_selection with symbol, string, whitespace, uppercase, nil, invalid
• Tested selection_label with valid and invalid selection values

Task 2: Test BulkSourceScraper batch limiting and determine_status

• Tested apply_batch_limit respects max_bulk_batch_size from config
• Tested determine_status returns :success, :partial, :error based on counts
• Tested determine_status :partial when only already_enqueued > 0
• Tested without_inflight excludes items with in-flight scrape_status
• Tested unknown enqueuer status handling

Task 3: Test Broadcaster setup and broadcast_source/broadcast_item

• Created new test file: test/lib/source_monitor/realtime/broadcaster_test.rb
• Tested setup! registers after_fetch_completed and after_item_scraped callbacks
• Tested setup! idempotent (no double-registration)
• Tested broadcast_source returns early when turbo_available? is false
• Tested broadcast_source returns early when source is nil after reload
• Tested broadcast_source calls broadcast_source_row and broadcast_source_show
• Tested broadcast_item calls Turbo::StreamsChannel with correct target/partial
• Tested broadcast_item rescues errors and logs them

Task 4: Test Broadcaster toast broadcasting and event handlers

• Tested broadcast_toast returns early when turbo_available? is false or message blank
• Tested broadcast_toast calls Turbo::StreamsChannel.broadcast_append_to
• Tested handle_fetch_completed broadcasts source and toast for each status
• Tested broadcast_fetch_toast for "fetched", "not_modified", "failed" statuses
• Tested handle_item_scraped broadcasts item, source, and toast
• Tested broadcast_item_toast for success and failed statuses

Task 5: Test Broadcaster helpers

• Tested reload_record returns nil for nil input, original record on reload error
• Tested turbo_available? true/false based on Turbo::StreamsChannel defined
• Tested register_callback no double-registration
• Tested log_error swallows errors from logger itself
• Tested broadcast_source_row and broadcast_source_show rescue and log errors
