+# Phase 1 Plan 1: Telegram Echo Bot Summary
+
+**n8n workflow with Telegram trigger, user ID authentication via environment variable, and echo response with timestamp**
+
+## Performance
+
+- **Duration:** 5 min
+- **Started:** 2026-01-28
+- **Completed:** 2026-01-28
+- **Tasks:** 2 (1 human-action, 1 auto)
+- **Files modified:** 1
+
+## Accomplishments
+- Telegram bot created and configured in n8n (user action)
+- n8n workflow JSON created with 4 nodes: Trigger, IF, Code, Send
+- User authentication via $env.TELEGRAM_USER_ID environment variable
+- Silent ignore for unauthorized users (no false branch nodes)
+- Echo response includes original text and ISO timestamp
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create Telegram Bot and Configure n8n** - (human action, no commit)
+2. **Task 2: Create n8n Workflow for Telegram Echo** - `9d503bb` (feat)
+
+## Files Created/Modified
+- `n8n-workflow.json` - Complete n8n workflow definition for import
+
+## Decisions Made
+- Used environment variable ($env.TELEGRAM_USER_ID) for auth - keeps sensitive data out of workflow JSON
+- HTML parse mode enabled for future formatting (bold, italic, links)
+- Silent ignore (empty false branch) for unauthorized users - no information leak
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - workflow JSON created and validated successfully.
+
+## User Setup Required
+
+User completed setup during Task 1:
+- Created Telegram bot via @BotFather
+- Configured TELEGRAM_BOT_TOKEN and TELEGRAM_USER_ID as n8n container environment variables
+- Created Telegram API credential in n8n
+
+## Next Phase Readiness
+- Workflow JSON ready for import into n8n
+- User must import workflow and activate it to test echo functionality
+- Foundation ready for Docker integration (Phase 2)
