Rehearsal tools, cue callers, and stage automation then depend on those representation choices. Moving a scene to another stage, replacing a console, changing fixture allocation, or rewriting a controller can alter fades, color states, holds, concurrent-cue behavior, or emergency transitions even when the cinematographer-approved lighting behavior is intended to remain unchanged.","actors":["Director of photography","Gaffer","Lighting console programmer","Lighting technician","Director","First assistant director","Stage electrical supervisor","Stage safety representative","Virtual-production or stage-control engineer"],"observable_state":"On an isolated rehearsal setup, equivalent cue requests sent through different console or rig implementations can produce different semantic endpoint states, transition timing, interpolation, conflict resolution, hold-and-resume behavior, or abort behavior. Client scripts invoke raw console macros, fixture identifiers, channel numbers, or network universes. Renumbering control addresses or reallocating supported fixtures can change cue results even when the declared lighting roles and target trajectories remain the same.","consequence":"A console or rig change can alter the photographed lighting behavior, require representation-specific cue reconstruction, or energize unintended endpoints. The production lacks one behavioral oracle for determining whether a replacement controller preserves both the approved cue trajectory and its side-effect boundaries.","affected_objective":"Preserve cinematographer-approved lighting-state trajectories and declared safe transitions across controller and fixture-allocation changes while permitting internal cue representations to vary.","intervention":"Define an opaque LightingCueProgram component by observable operations and laws. Its public surface loads a versioned program, reports required semantic lighting capabilities, validates an enrolled rig, arms a cue without changing output, triggers a cue, samples its declared semantic state at elapsed time, holds, resumes, cancels, executes an abort-to-safe transition, reports status, and freezes or supersedes the program. Model the abstract state as named semantic lighting endpoints, approved target states, cue transitions, interpolation rules, trigger conditions, concurrency and exclusion relations, hold semantics, enrolled-output boundaries, a safe state, and version lineage. Require deterministic abstract trajectories for the same valid event sequence; unchanged output after rejected or unarmed commands; explicit handling of unsupported capabilities and cue conflicts; immutability after freezing; abort precedence over ordinary cues; and output confined to enrolled endpoints. Hide fixture addresses, network universes, console syntax, fixture profiles, show-file layout, caches, driver algorithms, and physical allocation. Each console-and-rig adapter maps its concrete state to the same semantic endpoint state and is substitutable only if it passes a shared black-box suite within cinematography- and safety-approved observational tolerances established before testing.","structural_mapping":[{"archetype_element":"Abstract behavioral surface","domain_realization":"LightingCueProgram exposes capability validation,

This proposal concerns active on-set lighting execution: it separates approved cue trajectories and safety-bounded operations from console show files, fixture addressing, and rig allocation. Its abstract object is neither an editorial sequence nor a synchronized media group; it is a stateful lighting cue program with physical side effects. Its causal path runs from cue requests through an opaque controller contract and rig adapters to observable lighting states and safe transitions.
