      <critical>Keeping both the original and sharded versions defeats the purpose of sharding and can cause confusion</critical>
      <action>Present user with options for the original document:</action>

      <ask>What would you like to do with the original document `[source-document-name]`?

        Options:
        [d] Delete - Remove the original (recommended - shards can always be recombined)
        [m] Move to archive - Move original to a backup/archive location
        [k] Keep - Leave original in place (NOT recommended - defeats sharding purpose)

        Your choice (d/m/k):</ask>

      <check if="user selects 'd' (delete)">
        <action>Delete the original source document file</action>
        <action>Confirm deletion to user: "✓ Original document deleted: [source-document-path]"</action>
        <note>The document can be reconstructed from shards by concatenating all section files in order</note>
      </check>

      <check if="user selects 'm' (move)">
        <action>Determine default archive location: same directory as source, in an "archive" subfolder</action>
        <action>Example: /path/to/architecture.md → /path/to/archive/architecture.md</action>
        <ask>Archive location ([y] to use default: [default-archive-path], or provide custom path):</ask>
        <action if="user accepts default">Use default archive path</action>
        <action if="user provides custom path">Use custom archive path</action>
        <action>Create archive directory if it doesn't exist</action>
        <action>Move original document to archive location</action>
        <action>Confirm move to user: "✓ Original document moved to: [archive-path]"</action>
      </check>

      <check if="user selects 'k' (keep)">
        <action>Display warning to user:</action>
        <output>⚠️ WARNING: Keeping both original and sharded versions is NOT recommended.

          This creates confusion because:
          - The discover_inputs protocol may load the wrong version
          - Updates to one won't reflect in the other
          - You'll have duplicate content taking up space

          Consider deleting or archiving the original document.</output>
        <action>Confirm user choice: "Original document kept at: [source-document-path]"</action>
