## Status: COMPLETE

### Completed Steps
- [x] Initialized workspace and briefing
- [x] Read ORIGINAL_REQUEST.md, PROJECT.md, DISPATCH.md, remediation_plan.md, handoff.md
- [x] Step 1: Relocate untracked character assets (55 files) to 04_Assets/turnaround_sheets/
  * Verified: Exactly 62 canonical files remain in 04_Assets/characters/
  * Verified: git status -s 04_Assets/characters is completely clean
  * Verified: Exactly 55 files safely moved to 04_Assets/turnaround_sheets/
- [x] Step 2: Update turnaround generation tools & prompts
  * Updated tools/update_banana_turnaround_prompts.py (lines 426-427)
  * Updated tools/manage_turnaround_sheets.py (lines 17-18)
  * Ran python tools/update_banana_turnaround_prompts.py to sync 02_AI_Prompts/gemini_banana_prompts.json
  * Verified: all 80 turnaround paths in JSON point to 04_Assets/turnaround_sheets/
- [x] Step 3: Fix fallback concat stream specifier probe in 05_Production_Pipeline/production_orchestrator.py
  * Imported get_ffprobe from audio_continuity_engine (lines 105-110)
  * Replaced ffmpeg_exe.replace("ffmpeg", "ffprobe") with get_ffprobe() (line 1170)
- [x] Step 4: Add regression test for fallback concat with silent clip in tests/test_production_pipeline_m4.py
  * Added test_05_fallback_concat_with_silent_clip_without_crash
- [x] Step 5: Run full verification test suites (all 99 tests passed)
  * python -m pytest tests/test_m2_hygiene.py -v (6/6 PASSED)
  * python -m pytest tests/test_adversarial_m4_audio_concat_probe.py -v (5/5 PASSED)
  * python -m pytest tests/test_production_pipeline_m4.py -v (16/16 PASSED)
  * python -m pytest tests/test_critic_gate.py -v (30/30 PASSED)
  * python -m pytest tests/test_production_pipeline_m3.py tests/test_adversarial_m3_audio_engine.py tests/test_tier5_pipeline_hardening.py -q (42/42 PASSED)
- [x] Step 6: Write handoff report and notify orchestrator
