Elamur Groupantsonto-hsmap-selection
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.
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 |
|---|---|---|---|
behavior_complement | behavior_complement | partial source derived model | behavior_complement |
reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |
phrase_order | phrase_order | partial source derived model | phrase_order |
state_priority | state_priority | partial source derived model | state_priority |
singleton_margin | singleton_margin | partial source derived model | singleton_margin |
candidate_domain | candidate_domain | partial source derived model | candidate_domain |

onto-hsmap-selection
score(c)=WSD(c)+1[preferred]+chapter_share(lf(c)); best replaces only >old+1e-9
Epoch 2026-10-31
Specialized source fragment bytes [3692,7964); shared parent AST. Excludes unrelated parent operations and added test module.
approximant
Scoped forward
score(c)=WSD(c)+1[preferred]+chapter_share(lf(c)); best replaces only >old+1e-9
Domain
This byte-scoped operator uses the parent valid-state domain plus the following local restrictions:
Longest matching preference-fit phrase wins
Live before food in prefer/ckey
One sense→9.99 sentinel, not measured separation
Nonempty scored and valid Cid/lexfile required
No executable percentage surrogate established.
invariant
Local observations
Improvement<=1e-9 excludes replacement; negative state excludes bonus
Longest matching preference-fit phrase wins
Live before food in prefer/ckey
One sense→9.99 sentinel, not measured separation
Nonempty scored and valid Cid/lexfile required
cost
Scoped cost
O(S) score scan per candidate list plus phrase lookup/WSD work.
Restriction to this operator's traversed inputs; parent total is not charged to every fragment. No standalone measurement.
composition
Parent join
selection supplies the parent relation: score(c)=WSD(c)+1[preferred]+chapter_share(lf(c)); best replaces only >old+1e-9
Output compatibility is conditional on the local domain and earlier-branch exclusions. Other parent branches are outside this fragment.
models
behavior_complement
Improvement<=1e-9 excludes replacement; negative state excludes bonus
reverse_reconstruction
Score vector preimage constrained by sequential threshold and reported margin; common shifts preserve winner
phrase_order
Longest matching preference-fit phrase wins
state_priority
Live before food in prefer/ckey
singleton_margin
One sense→9.99 sentinel, not measured separation
candidate_domain
Nonempty scored and valid Cid/lexfile required

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.
