<objective>
Extract the container update flow into a dedicated sub-workflow to consolidate duplicated code (DEBT-03).

Purpose: The update logic is currently duplicated between the text command path (~lines 1656-2400) and the callback/inline keyboard path (~lines 3628-4010). Extracting to a sub-workflow creates a single source of truth, reduces main workflow complexity, and makes the update logic independently testable.

Output: New container-update sub-workflow JSON file and updated main workflow that calls it from both text and callback paths.

<task type="auto">
  <name>Task 1: Create container-update sub-workflow</name>
  <files>n8n-container-update.json</files>
  <action>
Create a new sub-workflow file `n8n-container-update.json` that encapsulates the entire container update flow.

**Input contract (Execute Sub-workflow Trigger with defined fields):**
```json
{
  "containerId": "string - Docker container ID",
  "containerName": "string - Container name for messages",
  "chatId": "number - Telegram chat ID",
  "messageId": "number - Message ID for inline edits (0 for text mode)",
  "responseMode": "string - 'text' or 'inline'"
}
```

**Flow to extract (from research):**
1. Inspect container configuration (get current image, config, host config)
2. Pull latest image (with :latest tag protection)
3. Inspect new image and compare digests
4. If update needed:
   - Stop container
   - Remove old container
   - Create new container with same config
   - Start new container
5. Clean up old image
6. Return result

**Output contract:**
```json
{
  "success": "boolean",
  "message": "string - Result message for user",
  "updated": "boolean - Whether update was performed",
  "oldDigest": "string (optional)",
  "newDigest": "string (optional)"
}
```

**Implementation notes:**
- Use "Define using fields" schema type for input contract (per research best practice)
- Include progress message editing for inline mode (messageId > 0)
- Include new message sending for text mode (messageId == 0)
- Handle both "update needed" and "already up to date" cases
- Preserve :latest tag protection (default to :latest if no tag)
- Preserve image cleanup after successful update
  </action>
  <verify>
- JSON file is valid: `python3 -c "import json; json.load(open('n8n-container-update.json'))"`
- Contains "executeWorkflowTrigger" node
- Has proper input schema with all 5 fields
  </verify>
  <done>Container update sub-workflow created with proper input/output contracts</done>
</task>

<task type="auto">
  <name>Task 2: Wire main workflow to use sub-workflow</name>
  <files>n8n-workflow.json</files>
  <action>
Modify the main workflow to call the container-update sub-workflow instead of having inline update logic.

**Changes needed:**

1. **Text command path:**
   - Find the text update flow (around the "Update Container" text command routing)
   - Replace inline update nodes with:
     a. Code node to prepare sub-workflow input (containerId, containerName, chatId, messageId=0, responseMode='text')
     b. Execute Sub-workflow node pointing to container-update workflow
   - Remove the duplicate update logic nodes from text path

2. **Callback/inline path:**
   - Find the callback update flow (around "Handle Update Action" or similar)
   - Replace inline update nodes with:
     a. Code node to prepare sub-workflow input (containerId, containerName, chatId, messageId from callback, responseMode='inline')
     b. Execute Sub-workflow node pointing to container-update workflow
   - Remove the duplicate update logic nodes from callback path

3. **Batch update path:**
   - Find where batch update calls individual container updates
   - Ensure it also uses the sub-workflow (may already be structured to call the same code)

**Execute Sub-workflow node configuration:**
```json
{
  "parameters": {
    "source": "database",
    "workflowId": "<will be set after import>",
    "mode": "once",
    "options": {
      "waitForSubWorkflow": true
    }
  },
  "type": "n8n-nodes-base.executeWorkflow"
}
```

**Important:** After extraction, the main workflow should be significantly shorter (estimate ~750 fewer lines per research).
  </action>
  <verify>
- Main workflow JSON is valid
- Contains "executeWorkflow" node(s) for update paths
- Old inline update nodes are removed (workflow is shorter)
  </verify>
  <done>Main workflow updated to call container-update sub-workflow from all update paths</done>
</task>

<task type="auto">
  <name>Task 3: Deploy and verify update functionality</name>
  <files>n8n-workflow.json, n8n-container-update.json</files>
  <action>
Deploy both workflows to n8n and verify all update paths work.

**Deployment steps:**
1. Import container-update sub-workflow to n8n via API (create new workflow)
2. Note the workflow ID assigned by n8n
3. Update main workflow's Execute Sub-workflow node(s) with correct workflow ID
4. Deploy main workflow update to n8n via API

**Verification tests:**

1. **Text command update:**
   - Send "update <container-name>" to bot
   - Should show update confirmation prompt
   - Confirm and verify update completes (or shows "already up to date")

2. **Inline keyboard update:**
   - Use /status to get container list
   - Select a container
   - Tap "Update" button
   - Should show confirmation dialog
   - Confirm and verify update completes with progress messages

3. **Batch update (if time permits):**
   - Initiate a batch update for 2 containers
   - Verify both update correctly
  </action>
  <verify>
- Sub-workflow imported and has valid ID in n8n
- Main workflow deployed with correct sub-workflow reference
- Text "update <name>" command works
- Inline keyboard update flow works
- Progress messages display correctly
  </verify>
  <done>Update sub-workflow deployed and all update paths verified working</done>
</task>

</tasks>

<verification>
1. n8n-container-update.json exists and is valid JSON
2. Sub-workflow has proper Execute Sub-workflow Trigger with input schema
3. Main workflow contains Execute Sub-workflow nodes calling update workflow
4. Main workflow line count reduced by ~500+ lines
5. Text command "update <container>" works end-to-end
6. Inline keyboard update with confirmation works end-to-end
7. "Already up to date" case handled correctly
8. Old image cleanup still occurs after successful update
</verification>

<success_criteria>
- Container update logic exists in ONE place (sub-workflow)
- Both text and inline update paths use the sub-workflow
- DEBT-03 (duplicated update flow) resolved
- All update functionality works as before
</success_criteria>

After completion, create `.planning/phases/10-workflow-modularization/10-02-SUMMARY.md`
