MDPE.16:0.1 - Working Distinctions

NameMeaning here
development alternativeAn identified actual or possible-future bearer or arrangement that can answer the same bounded development question through a materially different Method, structure, characteristic profile, use, or failure mode.
variantA bearer related to another bearer through a stated variation, derivation, transformation, lineage, or family relation. Resemblance or a shared label is insufficient.
live alternativeAn alternative with sufficient applicable evidence of availability for its named later use and conditions. A title, file, archive row, maintenance plan or former capability alone does not make it live.
branch availabilityAn obtaining combination of bearer or arrangement, capable performing Agent or whole, required capabilities and dependencies, access, permission, rights, resources, and usable configuration for the named later use.
upkeep or reconstruction resultThe world-side capability, access, relationship, configuration, or other condition obtained through a direct Music, Dance, teaching, archive, rights, capability, tool, event, operations, or engineering Method. A plan or record of that Work is not the result.
availability evidenceDated evidence that the branch can still be reconstructed, rehearsed, performed, taught, configured, accessed, or otherwise used as claimed under representative conditions.
stepping stoneAn alternative kept available because it enables later generation, learning, combination, representation change, source return, or reachability, even when it is not a current performance choice.
repertoireAlternatives available to named performing Agents or performing wholes in named Work, not every stored artifact under one style label.
selection-pressure claimA claim that may report only an association or trace, an obtaining rule or constraint, a causal-contribution hypothesis, or a bounded causal-use result. These claim strengths support different next moves.
archive/front membershipResults governed by C.18. Recorded, non-dominated, and live-for-this-question are different membership relations.
current OptionSetOptions currently available for one C.11 choice. The wider development set can supply candidates to it but is not one permanent OptionSet.

Novelty, diversity, usefulness, style recognition, embodied accessibility, technical feasibility, and cultural continuation are different characteristics and relations. A branch can be novel and unusable, useful and ordinary, weak now but a valuable stepping stone, visible but no longer reproducible, or stored but unavailable.
