Random Stage Tableau Composition Brief Generator

Description

Assign supplied performers to allowed poses and stage zones under occupancy capacities using bounded search; sightlines and physical safety remain caller-reviewed.

A structured creative brief combines a supplied bank of fictional material with explicit sequencing, timing, or compatibility rules. IDs and tags make those constraints inspectable; they do not assess the artistic meaning or quality of a scene.

Assign supplied performers to allowed poses and stage zones under occupancy capacities using bounded search; sightlines and physical safety remain caller-reviewed.

When to use this tool

Use this generator to create reproducible stage tableau composition cases from the supplied model or bank. Inspect the returned evidence before using cases in a test or exercise.

How to use the tool and how it works

Supply performers, zones, poses in the field shapes below. Set seed when you need an explicit replay.
Run the tool and correct any input error. For generated controls, distinguish a successful fixture containing an invalid case from failure to generate the fixture.
Read assignments, occupancy, rehearsalGroups, callerReviewRequired. Use the conventions below and keep answer-bearing fields separate when presenting an exercise.

Assign each performer a pose and an allowed zone using bounded randomized backtracking while respecting simultaneous zone occupancy capacities. Return the allocation, occupancy evidence, and rehearsal groups of up to four performers.^[1]

zones[].capacity	Capacity	Required. Safe integer; minimum 0; maximum 16.
poses	Poses	Required. Array of Object; no unknown keys.; minimum items 1; maximum items 16.
poses[].id	Literal identifier used to match records, independently of their display labels.	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 64.
poses[].text	Text	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 1024.
poses[].allowedZoneIds	Allowed Zone Ids	Required. Array of Text; minimum UTF-16 length 1; maximum UTF-16 length 64.; minimum items 1; maximum items 16.
seed	Optional numeric seed; takes precedence over context randomness. Without either, use the fixed tool.io default seed.	Optional. Safe integer.

Output field	Interpretation	Returned shape
assignments	Assignments	Required. Array of Object; no unknown keys.; minimum items 1; maximum items 16.
assignments[].performerId	Performer Id	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 64.
assignments[].zoneId	Zone Id	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 64.
assignments[].poseId	Pose Id	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 64.
assignments[].pose	Pose	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 1024.
occupancy	Occupancy	Required. Array of Object; no unknown keys.; minimum items 1; maximum items 16.
occupancy[].zoneId	Zone Id	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 64.
occupancy[].count	Requested count; the mechanics explain whether one draw expands into several returned records.	Required. Safe integer; minimum 0; maximum 16.
occupancy[].capacity	Capacity	Required. Safe integer; minimum 0; maximum 16.
rehearsalGroups	Rehearsal Groups	Required. Array of Array of Text; minimum UTF-16 length 1; maximum UTF-16 length 64.; minimum items 1; maximum items 4.; minimum items 1; maximum items 4.
callerReviewRequired	Caller Review Required	Required. Boolean; exactly true.
randomness	Replay metadata: source is seed or context; seed is the normalized 32-bit seed or null for a context source.	Required. Object; no unknown keys.
randomness.seed	Optional numeric replay seed; normalization and precedence are explained below.	Required. Safe integer. or Null.
randomness.source	Source	Required. Text; one of "context", "seed".

An explicit safe-integer seed takes precedence over injected context randomness and is normalized to an unsigned 32-bit integer. With no seed and no context source, replay uses the fixed tool.io default seed. A context source must return finite values from zero inclusive to one exclusive; its advancing state must be retained separately. randomness records the source and normalized seed, or null for context. These generators are not cryptographic random sources.

Limitations and assumptions

Capacities and allowed poses are supplied constraints. The tool does not check sightlines, movement, physical suitability, or safety; the output explicitly requires caller review.
A replay requires the same complete input and implementation. Randomized construction does not guarantee uniform coverage of every feasible output; finite samples can repeat unless a distinct-selection rule is explicitly stated.
The field tables state structural bounds; cross-field constraints and bounded search or output budgets also apply. Unknown keys are rejected where the object contract disallows them. Input errors are distinct from null fields and deliberate invalid controls in a successful output.

Alternative or Complementary methods

For a supplied example, inspect the returned construction or delegated check directly. To evaluate a consumer, also test cases chosen for its own boundaries; a generated finite corpus does not establish exhaustive coverage.
