Elamur Groupantsonto-query-meronymy
The groupant beside onto/src/query.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 | approximant |
| ast | partial | ../syntax.json |
| composition | partial | composition |
| cost | partial | cost |
| descriptant | present | descriptant |
| invariant | partial | invariant |
| tests | executed bounded checks | tests |
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.
| id | type | label | where |

reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |

onto-query-meronymy
owners=sort ancestors(depth,Cid); walk incoming PartOf<=3, MemberOf/MadeOf at depth0
Epoch 2026-10-31
Specialized source fragment bytes [14379,18068); shared parent AST. Excludes unrelated parent operations and added test module.
approximant
Scoped forward
owners=sort ancestors(depth,Cid); walk incoming PartOf<=3, MemberOf/MadeOf at depth0
Domain
This byte-scoped operator uses the parent valid-state domain plus the following local restrictions:
Dedup by(part,rel), not owner
Inherited owner carries BFS taxonomic Chain
Incoming PartOf/MemberOf; outgoing MadeOf
Missing lexical or part witness→Unknown
No executable percentage surrogate established.
invariant
Local observations
Depth4 parts and recursive members excluded; absent has_part witness excludes No
Dedup by(part,rel), not owner
Inherited owner carries BFS taxonomic Chain
Incoming PartOf/MemberOf; outgoing MadeOf
Missing lexical or part witness→Unknown
cost
Scoped cost
Sort Va owners O(Va log Va); traverse incoming PartOf frontiers to depth3 for each owner with global pair dedup. Work proportional to visited adjacency plus owner chains/path clones; has_part further computes ancestry per candidate part and compares target senses.
Symbolic accounting; no timing claim or whole-system speed bound.
composition
Parent join
meronymy supplies the parent relation: owners=sort ancestors(depth,Cid); walk incoming PartOf<=3, MemberOf/MadeOf at depth0
Output compatibility is conditional on the local domain and earlier-branch exclusions. Other parent branches are outside this fragment.
models
behavior_complement
Depth4 parts and recursive members excluded; absent has_part witness excludes No
reverse_reconstruction
Returned path constrains first owner and CSR edges; later duplicates/deeper edges unconstrained
seen_relation
Dedup by(part,rel), not owner
owner_proof
Inherited owner carries BFS taxonomic Chain
part_direction
Incoming PartOf/MemberOf; outgoing MadeOf
unknown_boundary
Missing lexical or part witness→Unknown
tests
Evidence
Parent tests.md identifies selected actual-code checks. Fragment is a source-scoped partial model; parent finite fixtures do not establish exhaustive branch coverage or every local equation.
