- 2 test string literals updated ✓
- CLAUDE.md updates ✓
- **UNPLANNED:** 15 kollabor/ui/*.py files had broken relative imports
- **UNPLANNED:** 6 kollabor/io/input/*.py files had broken key_parser imports

## Files Modified

## Remaining Shims (Out of Scope)

Phase 5B only removed kollabor-tui shims. The following packages still have shims:

### kollabor-events (Phase 2 shims) - 8 files
- kollabor/events/executor.py
- kollabor/events/ready_message.py
- kollabor/events/hook_adapter.py
- kollabor/events/bus.py
- kollabor/events/processor.py
- kollabor/events/__init__.py
- kollabor/events/registry.py
- kollabor/events/models.py

### kollabor-agent (Phase 3 shims) - 5 files
- kollabor/utils/shell_executor.py
- kollabor/llm/shell_command_service.py
- kollabor/llm/mcp_integration.py
- kollabor/llm/file_operations_executor.py
- kollabor/llm/tool_executor.py

### kollabor-ai (Phase 4 shims) - 15+ files
- kollabor/models/base.py
- kollabor/llm/response_parser.py
- kollabor/llm/api_adapters/__init__.py
- kollabor/llm/providers/__init__.py
- kollabor/llm/providers/base.py
- kollabor/llm/providers/registry.py
- kollabor/llm/providers/transformers.py
- kollabor/llm/providers/anthropic_provider.py
- kollabor/llm/providers/azure_provider.py
- kollabor/llm/providers/custom_provider.py
- kollabor/llm/providers/gemini_provider.py
- kollabor/llm/providers/gemini_transformer.py
- kollabor/llm/providers/openai_provider.py
- kollabor/llm/providers/openai_responses_provider.py
- kollabor/llm/providers/openai_responses_transformer.py
- kollabor/llm/providers/openrouter_provider.py
- kollabor/llm/providers/security.py
- kollabor/llm/providers/models.py
- kollabor/llm/providers/errors.py

## Future Phases

**Phase 5C:** Remove kollabor-events shims (8 files)
**Phase 5D:** Remove kollabor-agent shims (5 files)
**Phase 5E:** Remove kollabor-ai shims (15+ files)

Alternative: Single Phase 5CDE sweep removing all 28 remaining shims.

## Verification

```bash
# Imports work
python -c "from kollabor.io import TerminalState, KeyParser; print('ok')"
python -c "from kollabor_tui.design_system import T, S, Box; print('ok')"

# App boots
python main.py --help

# No broken relative imports
grep -r "from \.\.key_parser import" kollabor/  # should return nothing
grep -r "from \.\.design_system import" kollabor/ui/  # should return nothing
```

## Lessons Learned

1. **"Zero consumers" claim was wrong** - The plan stated all consumers had been rewired, but 21 files still had relative imports to the deleted shims.

2. **Relative imports bypass __init__.py** - Files importing via `from ..key_parser import` don't go through the package's __init__.py re-exports.

3. **Always grep for actual usage** - Don't trust claims about imports. Verify with:
   ```bash
   grep -r "from \.\.shim_name import" kollabor/
   ```

4. **Parallel agent work** - Another agent fixed the 21 broken imports during this phase, showing good coordination.

## Commit Message

```
Phase 5B: Remove kollabor-tui backward-compat shims

- Delete 60 .bak files from refactoring phases
- Update docstring examples in kollabor-tui (from kollabor. -> from kollabor_tui.)
- Update test string literals
- Fix 21 files with broken relative imports to deleted shims
