"""Unit tests for connectonion/cli/commands/reset_commands.py

Tests cover:
- handle_reset: DESTRUCTIVE operation that deletes all config
- User confirmation with 'Y'
- Deletion of ~/.co/keys/, host.yaml, keys.env
- Recreation of directory structure
- New Ed25519 keypair generation
- Authentication flow after reset
- Cancellation on non-Y input

SAFETY: All tests use temporary directories to avoid affecting real ~/.co/
"""

"""
LLM-Note: Tests for CLI reset command (co reset)

What it tests:
- TestHandleResetNoConfig: Behavior when no config exists
  - test_reset_no_global_config: Error when ~/.co/ doesn't exist
- TestHandleResetConfirmation: User confirmation workflow
  - test_reset_cancelled_on_n: Cancel on 'n' input
  - Verification of DESTRUCTIVE deletion with 'Y' confirmation

Components under test:
- connectonion.cli.commands.reset_commands.handle_reset
