Elamur Groupantsworld-qud-eligibility
The groupant beside world/src/qud.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.
Facts
Implementation material. A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.
Components
| component | label | where |
|---|---|---|
| approximant | partial source model | forward |
| ast | partial | ../syntax.json |
| composition | partial source model | composition |
| cost | partial source model | cost |
| descriptant | partial source model | epoch-memory |
| invariant | partial source model | invariant |
| tests | partial source model | checks |
Obernants
The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

Model text
forward
Congruence requires shared content unless question content empty, then a wh-specific filler. Complete means nonpartial filler and predicate present (or YesNo). Proper names bypass lexical animacy; nouns require Animate.
invariant
Nonempty disjoint question content rejects; missing wh slot rejects. Slot completeness is independent of stack priority. Unknown noun animacy does not satisfy Who.
cost
O(T^2) case-child scans per question plus set and external animacy costs.
composition
This fragment shares source and state with its siblings; root composition specifies ordering and latent dependencies. It is not an independent replacement API.
epoch-memory
Predicted latest eligible and partial persistence; 46,656 bounded histories confirm. Generic-hedge prose overstates implementation: Who+maybe is complete. No production repair or continuous approximation metric proposed.
checks
Five native tests: 46,656 six-step histories (279,936 transitions), uncertainty interaction, empty-content slot gate, four polarity preimages, ordered givenness. Fragment scopes are defined by source byte ranges; root evidence distinguishes executed helper tests from inspection-only branches.
behavior-complement
Within the scoped input/output universe, violating uncertainty or novelty is excluded by the source model. This inner constraint family does not claim a complete complement.
reverse-reconstruction
Converse retains all inputs compatible with the scoped output and fixed dependencies; projections and discarded candidates generally create multiple antecedents. No single inverse is claimed.
uncertainty
Only YesNo hedges and indefinite fallbacks mark partial; Who+maybe with new proper noun remains complete.
novelty
Where/When/What usually test q.words novelty; Why and case-based How do not uniformly do so.
