+<objective>
+Import the workflow into n8n and verify end-to-end Telegram communication works.
+
+Purpose: Confirm the foundation is solid before building Docker features on top.
+Output: Verified working bot that echoes messages to authorized user only.

+  <action>
+Import the workflow JSON into n8n:
+
+1. Open n8n UI
+2. Go to Workflows -> Import from File
+3. Select `n8n-workflow.json` from the project
+4. Review the imported workflow
+5. Ensure Telegram credential is selected in Telegram nodes
+6. Activate the workflow (toggle on)

+  <name>Task 2: Verify Authorized User Echo</name>
+  <what-built>Telegram bot that echoes messages back with timestamp</what-built>
+  <how-to-verify>
+1. Open Telegram
+2. Find your bot (search for the username you created)
+3. Send a test message: "Hello bot!"
+4. Verify you receive a response like:
+   ```
+   Got: Hello bot!
+
+   Processed: 2026-01-28T12:34:56.789Z
+   ```
+5. The timestamp should be within seconds of when you sent the message
+6. Try another message to confirm consistency

+  <name>Task 3: Verify Unauthorized User Blocked</name>
+  <what-built>Silent ignore for unauthorized Telegram users</what-built>
+  <how-to-verify>
+**Option A (if you have another device/account):**
+1. From a different Telegram account, send a message to the bot
+2. Verify NO response is received (bot appears offline)
+3. Wait 30 seconds to confirm silence
+
+**Option B (if only one account):**
+1. Temporarily change TELEGRAM_USER_ID in n8n to a wrong value
+2. Restart n8n
+3. Send a message to the bot
+4. Verify NO response
+5. Restore correct TELEGRAM_USER_ID
+6. Restart n8n
+7. Verify echo works again
+
+The bot should give no indication it received the message from unauthorized users.
+  </how-to-verify>
+  <resume-signal>Type "secure" if unauthorized users are blocked, or describe any issues</resume-signal>

+1. Workflow imported and active in n8n
+2. Authorized user receives echo with timestamp
+3. Unauthorized user receives no response
+4. Bot responds within a few seconds

+<success_criteria>
+- Telegram message to bot receives echo response
+- Echo includes original message and timestamp
+- Unauthorized users get silent ignore (no response)
+- REQ-01 (send/receive messages) validated
+- REQ-09 (user ID auth) validated
