[C4 HL-026] Deliver one projection or room-scale performance with a runbook #36

Outcome

Realize one approved patch in an actual performance environment.

Placement and activation

• Circle: C4 — Performance, space, and participation
• System responsibilities: Product / Platform
• Capability coverage: 02 Product Applications & Interfaces; 06 Infrastructure & Runtime; 07 Reliability, Observability & Operations; 08 Quality, Testing & Evaluation; 11 Documentation & Knowledge
• Planning status: Conditional; activate only when the requirement below is met.
• Activation: An actual venue, commission, or documented performance test exists.
• Parent epic: [EPIC C4] Performance, space, and participation #7; master roadmap: [MASTER EPIC] Hole-loop: concentric evolution within Persona / Visual Form Canon #2.

Dependencies

• HL-010 #20
• HL-018 #28

Acceptance evidence

• Support fullscreen/kiosk and projection with operator-only setup, restart/recovery, offline assets, and distinct presentation controls.
• Record venue dimensions, viewer distance, scale, display/color calibration limitations, sound constraints, equipment, and accessible alternative access.
• Separate machine score execution from performer interpretation; document two realizations where a human instruction allows difference.
• Rehearse interruptions, display loss, audio loss, restart, and a fallback version; identify operator and incident/contact path.
• Retain video/photos or another approved performance record, edition IDs, traversal data where applicable, and an artist evaluation.
• Use HL-024 #34 for selected sound and HL-025 #35/HL-027 #37 for selected participation. A silent projected text score does not depend on completing all those features or the general studio.

Completion and scope

Attach the actual artifact or commit, relevant verification, limitations, and an artist decision where a composition changes. This issue plans authorized work; creation does not claim implementation or deployment. Preserve independent work/source identities and private source boundaries. Repository creation requires the extraction evidence in HL-004 #13 and HL-045 #14.
