Your working directory is: c:\Projects\KieuStory\.agents\teamwork\challenger_m5_assembly_2

You MUST read:
- c:\Projects\KieuStory\.agents\teamwork\ORIGINAL_REQUEST.md
- c:\Projects\KieuStory\PROJECT.md
- c:\Projects\KieuStory\.agents\teamwork\worker_m5_1\handoff.md
before starting work.

Empirically challenge the grand master assembly pipeline:
1. Run `python 05_Production_Pipeline/assemble_ep01_feature.py --check` and verify exit code 0.
2. Run `python 05_Production_Pipeline/assemble_ep01_feature.py --dry-run` and verify exit code 0.
3. Test programmatic import and invocation:
   - Verify `from assemble_ep01_feature import assemble_grand_feature` works cleanly without exiting or printing uncontrolled errors.
4. Test character asset resolution in `05_Production_Pipeline/production_orchestrator.py`:
   - Verify `resolve_start_frame()` with verbose aliases cleanly maps to existing files in `04_Assets/characters/`.
5. Provide an explicit verdict: APPROVE or REQUEST_CHANGES in handoff.md following the 5-component protocol, and send a message back.
