Zacus — Conversation Summary (bundle v3)

This bundle consolidates the key outputs from the conversation:

• Promptable scenario template (user-edited section: prompt_input)
• Canonical scenario YAML (STEP_/SCENE_ conventions)
• Runtime JSON (DEFAULT.json)
• FSM diagram (Mermaid)
• Codex prompt to update repo targets
• Narrative zacus_v2.yaml aligned with the runtime + real-world gameplay

Key decisions captured:

• Prototype is U-SON.
• Act 1 (~45 min): LA 440 Hz stabilization (STEP_LA_DETECTOR).
• Act 2 (~60 min): Zone 4 piano-alphabet puzzle → play "LEFOU" (letters randomly placed; A anchored on LA 440 Hz).
• QR final payload is "WIN", hidden behind the portrait in the Archives.
• After QR success: Media Hub + persistent boot into media_manager.
