Elamur Groupantsworld-idioms-dictionary
The groupant beside world/src/idioms.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
Skip header; eligible POS/title grammar; optional fillers after first word; key first word and sole survivor; first minimum rank idiom<verb-phrase<phrase<other wins.
invariant
Each pair has one selected row: minimal rank, earliest tie. Value retains title/kind/gloss; key alone loses fillers.
cost
Linear input scan plus ordered-map/set insertion and string comparisons; root cost states composition. No timing claim.
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 first minimum dictionary rank and first MWE row; finite tests confirm. Limitations: substring flags, unconditional first-line discard, duplicate last pair versus summed marginals, absent phrasal book gate and unused k%1 set. Production unchanged.
checks
Five native tests: 64 rank triples, eight phrase/POS contexts plus header, 80 MWE flag/type/title combinations, reversed order, four pair-key preimages. Full run/exports not executed. 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 ties or title-fiber 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.
ties
Select lexicographic minimum (rank,row index). All 64 triples of four ranks checked with independent minimum/first oracle.
title-fiber
Four kick bucket titles share key; complete values retain selected title. Context matching here is title grammar, not sentence meaning.
