PLAN 03 SUMMARY

What Was Built

• Wired AIA certificate resolution into FeedFetcher's SSL error handling
• On Faraday::SSLError, attempts intermediate cert recovery via AIAResolver.resolve before raising
• Guard flag @aia_attempted prevents infinite recursion; rescue StandardError => nil ensures recovery never makes things worse
• Tags instrumentation_payload[:aia_resolved] = true on successful AIA recovery
• 3 integration tests: success retry path, nil fallback to ConnectionError, non-SSL skip

Files Modified

• lib/source_monitor/fetching/feed_fetcher.rb — split SSL rescue, add attempt_aia_recovery
• test/lib/source_monitor/fetching/feed_fetcher_test.rb — 3 AIA resolution tests
