The production requirement asks a preflight service to terminate on every well-formed package and answer exactly whether every possible viewing session will reach an approved ending within its declared duration while using only cleared assets. The package class, environment behavior, and meaning of the universal guarantee are not fixed. A plug-in can simulate an arbitrary computation, so repeated analyzer timeouts cannot establish either a violation or undecidability; conversely, successful tests on selected sessions cannot establish the requested class-wide guarantee.","actors":["interactive editor","narrative systems designer","post-production pipeline engineer","asset-clearance reviewer","producer or release approver","distribution-platform operator"],"observable_state":"The release interface exposes a Boolean pass/fail result for packages containing unrestricted scripts. Some analyses terminate on sampled paths, while others hit a resource limit; the latter are recorded as failures without distinguishing a found violation, an unresolved analysis, out-of-scope behavior, or tool failure. The documentation does not bind the result to a script fragment, execution model, environment assumptions, or exploration bound.","consequence":"A timeout may incorrectly block a releasable cut or be waived as an engineering nuisance, while a passing sample may be treated as proof that all sessions terminate and avoid uncleared assets. The team can therefore spend implementation effort pursuing an unsupported universal verifier, make release decisions from overstated evidence, or silently narrow accepted packages while preserving the unrestricted product claim.","affected_objective":"Make defensible release-preflight decisions for executable screen works while preserving truthful guarantees, usable creative scope, and traceability between each verdict and the model under which it was obtained.","intervention":"Replace the Boolean universal verifier with a computability-boundary preflight. First freeze an instance contract covering package syntax, asset identifiers, audience events, external calls, duration semantics, and the execution model. Test the unrestricted total-exact requirement with a property-preserving reduction: given a program and input, construct a deterministic media plug-in that reaches an approved end state exactly when that computation halts. If the construction and its assumptions survive independent review, do not offer a total exact verdict for the unrestricted class. Define an enforceable finite-state authoring fragment with bounded event alphabets, bounded counters, declared assets, no dynamic code loading, and no unmodeled external calls; exhaustively model-check that fragment and issue exact, terminating verdicts relative to its declared bounds. Route unrestricted plug-ins to a sound over-approximate analysis and bounded concrete witness search. Return CLEAR only when the abstraction proves the required properties, VIOLATION-WITNESS when a replayable counterexample is found, and otherwise UNKNOWN, OUT-OF-SCOPE, or TOOL-FAILURE. Attach the mode, bounds, assumptions, certificate, and recheck triggers to every result; retain release authority with the designated human approver.","structural_mapping":[{"archetype_element":"Problem-Class Specification","domain_realization":"Define the target as all encoded interactive-film packages and the property as universal
