Tasks Completed

Task 1: Extract basic settings (HTTP, Fetching, Health, Scraping)

• Created lib/source_monitor/configuration/http_settings.rb (43 lines)
• Created lib/source_monitor/configuration/fetching_settings.rb (27 lines)
• Created lib/source_monitor/configuration/health_settings.rb (27 lines)
• Created lib/source_monitor/configuration/scraping_settings.rb (39 lines)
• Removed class bodies from configuration.rb, added require statements
• All 81 configuration tests pass

Task 2: Extract complex settings (Realtime, Retention, Authentication)

• Created lib/source_monitor/configuration/realtime_settings.rb (95 lines, includes SolidCableOptions)
• Created lib/source_monitor/configuration/retention_settings.rb (45 lines)
• Created lib/source_monitor/configuration/authentication_settings.rb (62 lines, includes Handler struct)
• All 81 configuration tests pass

Task 3: Extract registry, events, models, and definition classes

• Created lib/source_monitor/configuration/scraper_registry.rb (67 lines)
• Created lib/source_monitor/configuration/events.rb (60 lines)
• Created lib/source_monitor/configuration/models.rb (36 lines)
• Created lib/source_monitor/configuration/model_definition.rb (108 lines, includes ConcernDefinition)
• Created lib/source_monitor/configuration/validation_definition.rb (32 lines)
• Configuration.rb reduced to 87 lines
• All 81 configuration tests pass

Task 4: Verify line counts, RuboCop, and full test suite

• Configuration.rb: 87 lines (target: under 120)
• 12 extracted files, none exceeds 300 lines (largest: model_definition.rb at 108)
• RuboCop: 13 files inspected, 0 offenses
• Full suite: 760 runs, 28 errors (all from concurrent dev work on FeedFetcher/ImportSessions extraction, not from this plan)

None	No deviations from plan	N/A

Verification Results

Check	Result
wc -l lib/source_monitor/configuration.rb	87 lines (target: <120)
ls lib/source_monitor/configuration/*.rb | wc -l	12 files
grep -c 'class.*Settings|class.*Registry|class.*Events|class.*Models|class.*Definition' lib/source_monitor/configuration.rb	0 (all nested classes extracted)
bin/rails test test/lib/source_monitor/configuration_test.rb	81 runs, 178 assertions, 0 failures, 0 errors
bin/rubocop lib/source_monitor/configuration.rb lib/source_monitor/configuration/	13 files inspected, 0 offenses

Success Criteria

• Configuration main file under 120 lines (87, down from 655)
• 12 extracted files in lib/source_monitor/configuration/
• No extracted file exceeds 300 lines (largest: 108)
• Public API unchanged -- SourceMonitor.configure { |c| c.http.timeout = 30 } works
• All existing configuration tests pass without modification (81 runs, 0 failures)
• RuboCop passes on all modified/new files
• REQ-09 satisfied
