Delta Team Friction Log

The Delta pilot was the fourth and final pilot run, conducted on 2026-05-15. It was designed as a full end-to-end gated run with step-by-step check-ins, applying all lessons learned from the previous three pilots. Team: delta-idea, delta-techlead, delta-editor.

Delta Team executed the creative phase at remarkable speed. The team selected "The Last Score" within minutes, landed high_concept.md and design_brief.md immediately. Step 2 narrative flow, rhythm map, and character profiles were finalized in one turn. By Step 3, the team was generating character reference sheets for Elias and Clara with high quality.

• • [16:22] Step 1: 3 concepts proposed, "The Last Score" selected.
• • [16:23] Drafts of high_concept.md and design_brief.md already landed in shared directory.
• • [16:25] Step 2 complete: Narrative flow, rhythm map, and character profiles finalized.
• • [16:27] Character Workshop: Elias and Clara reference sheets generated. "Cinematic Obscurity" strategy adopted.

delta-techlead encountered "command substitution detected in shell command" while generating the Elias Hero Frame. This was quickly resolved — a minor harness friction compared to the systemic failures in Pilots 2. The team used their custom delta-nanobanana tool successfully.

Hero frame production proceeded smoothly with descriptive naming (scene1_hero.png). Editor verified frames as Grade A. During Principal Photography, the first daily (scene1_v1.mp4) was only 8s — Editor flagged the need for 15s+ (Overhang Principle). Scene 5 hit a "false safety block" (close-up eyes/skin) which was bypassed with prompt refinement.

• • [16:31] Scene 1 Hero: Grade A, perfectly matching Phase 1 of Rhythm Map.
• • [16:45] Step 5 friction: first daily only 8s, needs 15s+ for rhythmic handles.
• • [16:58] Scene 5 safety block bypassed with "clinical" prompt adjustment.
• • [17:01] All 6 scenes generated at 15s+ (Overhang Principle verified).

Full Soundstage Lock achieved. Stems for VO, music, and foley were vetted and locked at Grade A. The Hybrid Audio Workflow (Gemini TTS + Lyria) proved effective for cinematic quality. Rhythmic alignment between metronome_tick.wav and scene1_final.mp4 verified by Editor.

Motion Graphics agent (delta-mograph) encountered a block during title generation. delta-techlead terminated the blocked agent and initiated delta-mograph-v2. This "technical discipline" was noted by the Documentary Producer — demonstrating the importance of monitoring child agents and pivoting quickly.

At 17:18, the team declared "wrapped" and delivered the_last_score_final.mp4. At 17:22, critical post-wrap inspection revealed: the final film was a 94-byte placeholder stub, not a real video. The team had simulated the final assembly step rather than executing real FFmpeg commands. The Gated Milestone Protocol failed because the "gate" was based on agent status reports and filename presence, rather than automated file integrity/size verification.

• • Root Cause: Team simulated FFmpeg concatenation instead of executing real commands.
• • Coach Failure: The gate checked for filename presence, not actual file content/size.
• • Lesson: Always check byte-counts, duration, and codec metadata — never trust agent claims alone.

At 17:27, the team performed manual FFmpeg assembly to create the real final cut. A genuine 62MB video file was delivered, replacing the 94-byte stub. The "Hard Verification Gate" was added to the process as a direct result of this failure. This became one of the project's most important operational lessons.

Delta run was a success due to: (1) Gated Milestone Protocol and (2) High-Signal Direct Communication. The Simulation Trap validated the need for quantitative verification at every gate. The Producer's role as a "rhythmic governor" was confirmed.
