Issue 6-027b: Add Boost/Announce Activity Extraction Support

Current Behavior

  • Fediverse extraction processes only Create activities (original posts)
  • Announce activities (boosts/reblogs) are ignored during extraction
  • Total outbox contains 6458 items: 6000 Create + 458 Announce activities
  • No option to include boosted content in extracted dataset

Intended Behavior

  • Default mode excludes boosted posts (current behavior preserved)
  • "Dirty" mode flag enables inclusion of boosted content
  • Announce activities extract referenced post content when available
  • Clear distinction between original posts and boosted content in metadata
  • Configurable boost inclusion for different use cases

Suggested Implementation Steps

  1. ActivityPub Analysis: Parse Announce activity structure and referenced objects
  2. Boost Detection: Identify and categorize Announce vs Create activities
  3. Content Resolution: Extract boosted post content from referenced objects
  4. Metadata Enhancement: Add boost indicators and original author information
  5. Configuration Integration: Add boost inclusion flag to extraction options

Technical Approach

Activity Type Detection

function categorize_activity(activity)
    if activity.type == "Create" and activity.object and activity.object.type == "Note" then
        return "original_post", activity.object
    elseif activity.type == "Announce" then
        return "boost", activity.object
    else
        return "unknown", nil
    end
end

Boost Content Extraction

function extract_boost_content(announce_activity, extraction_options)
    -- Handle different boost reference formats
    local boosted_object = announce_activity.object
    
    -- If object is URI, attempt to resolve (may not be available)
    if type(boosted_object) == "string" then
        -- Reference to external post - limited content available
        return {
            type = "external_boost",
            uri = boosted_object,
            boost_timestamp = announce_activity.published,
            content = "External post: " .. boosted_object,
            metadata = {
                is_boost = true,
                boost_type = "external",
                original_uri = boosted_object
            }
        }
    end
    
    -- If object is embedded, extract full content
    if type(boosted_object) == "table" and boosted_object.content then
        return {
            type = "embedded_boost", 
            content = boosted_object.content,
            original_author = boosted_object.attributedTo,
            boost_timestamp = announce_activity.published,
            original_timestamp = boosted_object.published,
            metadata = {
                is_boost = true,
                boost_type = "embedded",
                original_author = boosted_object.attributedTo,
                boost_date = announce_activity.published,
                original_date = boosted_object.published
            }
        }
    end
    
    return nil
end

Enhanced Processing Loop

function process_fediverse_with_boosts(data, extraction_options)
    local poems_json = {}
    local boost_count = 0
    local original_count = 0
    
    for key, activity in pairs(data.orderedItems) do
        local activity_type, content_object = categorize_activity(activity)
        
        if activity_type == "original_post" then
            -- Process original posts (existing logic)
            local poem_entry = process_original_post(content_object, key)
            if poem_entry then
                table.insert(poems_json, poem_entry)
                original_count = original_count + 1
            end
            
        elseif activity_type == "boost" and extraction_options.include_boosts then
            -- Process boosted content when enabled
            local boost_content = extract_boost_content(activity, extraction_options)
            if boost_content then
                local boost_entry = {
                    id = string.format("%04d", key),
                    category = "fediverse_boost",
                    source_file = "outbox.json",
                    creation_date = boost_content.boost_timestamp,
                    content = boost_content.content,
                    metadata = boost_content.metadata
                }
                table.insert(poems_json, boost_entry)
                boost_count = boost_count + 1
            end
        end
    end
    
    return {
        poems = poems_json,
        extraction_summary = {
            original_posts = original_count,
            boosted_posts = boost_count,
            total_extracted = #poems_json,
            boost_inclusion_enabled = extraction_options.include_boosts
        }
    }
end

Configuration Options

{
  "include_boosts": false,  // Enable boost extraction
  "boost_category": "fediverse_boost",  // Category for boosted content
  "resolve_external_boosts": false,  // Attempt external boost resolution
  "max_boost_content_length": 2000,  // Limit boost content size
  "boost_metadata_detail": "full"  // "minimal" or "full" boost metadata
}

Privacy Considerations

  • Boosted content may contain additional privacy-sensitive information
  • Original author attribution in boost metadata requires careful handling
  • External boost URIs may expose server information
  • Privacy anonymization must apply to both original and boosted content

Quality Assurance Criteria

  • Default behavior unchanged (boosts excluded)
  • "Dirty" mode successfully includes boost content
  • Clear metadata distinction between original and boosted posts
  • No performance degradation from boost processing
  • Proper error handling for malformed boost activities
  • Privacy filtering applies consistently to all extracted content
