onto-hsmap-isa-gate

The groupant beside onto/src/hsmap.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.

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.

Verdict=first witness in ancestry,other-sense,part,taxon,modifier,missing-head,made,source,LCA

Epoch 2026-10-31

Specialized source fragment bytes [11385,14995); shared parent AST. Excludes unrelated parent operations and added test module.

approximant

Scoped forward

Verdict=first witness in ancestry,other-sense,part,taxon,modifier,missing-head,made,source,LCA

Domain

This byte-scoped operator uses the parent valid-state domain plus the following local restrictions:

Only first60 incoming MemberOf edges examined

query::parts_of includes inherited bounded meronym paths

Min sum depth then Cid; Near requires head depth1

No chosen head yields Unknown before material/LCA

No executable percentage surrogate established.

invariant

Local observations

Direct ancestor excludes weaker Part/OtherSense despite simultaneous evidence

Only first60 incoming MemberOf edges examined

query::parts_of includes inherited bounded meronym paths

Min sum depth then Cid; Near requires head depth1

No chosen head yields Unknown before material/LCA

cost

Scoped cost

Ancestry BFS for chosen sense, alternatives and chosen heads; query::parts_of adds owner/meronym work. Taxon scan at most60 member edges, each may BFS. LCA scans chosen ancestry; no teacher or filesystem effect.

Symbolic accounting; no timing claim or whole-system speed bound.

composition

Parent join

isa-gate supplies the parent relation: Verdict=first witness in ancestry,other-sense,part,taxon,modifier,missing-head,made,source,LCA

Output compatibility is conditional on the local domain and earlier-branch exclusions. Other parent branches are outside this fragment.

models

behavior_complement

Direct ancestor excludes weaker Part/OtherSense despite simultaneous evidence

reverse_reconstruction

Yes iff an ancestor witness in heads_all exists at first gate; Part requires earlier failures

taxon_cap

Only first60 incoming MemberOf edges examined

part_join

query::parts_of includes inherited bounded meronym paths

lca_tie

Min sum depth then Cid; Near requires head depth1

fallback_domain

No chosen head yields Unknown before material/LCA

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.
