mova-topic-corpus-world
The groupant beside tools/topic-corpus/src/world.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 | Forward approximant |
| ast | partial | syntax.json |
| composition | partial | Composition |
| cost | partial | Cost |
| descriptant | present | Descriptant |
| invariant | partial | Invariant |
| tests | finite evidence | tests.md |
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 |
Model text
Descriptant
The small world of one paper against the cross corpus: entities (acronyms, proper names, frequent nouns) with mentions, the paper's own expansions, the best neighbour explanation and the corpus documents that speak of them; statements sorted into claim, method, result, statement with frames and entities. Source: tools/topic-corpus/src/world.rs.
Forward approximant
parsed(paper) -> entity counts -> ranking (acronyms first) -> definitions/links/explanations (lazy) -> statements with kinds -> world.json.
Invariant
Deterministic for the same corpus state (checked twice on bryant-2017).
Cost
Linear in paper sentences times entities plus text scans of the registered documents.
Composition
Parent: topic-corpus.
behavior_complement
Does not decide truth or importance; the kind of a statement is a lexical heuristic. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
Statements keep their sentence index and text; links keep document ids and counts only. No unique inverse is claimed.
tests.md
world::tests (GEC explained by and linked to the reference; byte-identical rebuild). Live 2026-11-04 bryant-2017: 241 sentences, 40 entities, 25 claims, 27 results.
cargo test --manifest-path tools/topic-corpus/Cargo.toml --offline with WORLD_EN_MODEL=$MOVA_DATA/download/0/0.4/en.bin (18 unit tests; fixture library, fake papers binary, fake terminal, local Sea Spider store; two identical runs on 2026-11-04). Without the model the model-dependent tests report a skip.
Negative controls 2026-11-04 (each red, then restored): public admission without the origin condition; assert_public without the Sea Spider/draft/note refusals; seeding without the learner lock; shadow-library filter off; public citing that ignores refusals; cache eviction ignoring the hot pin.
These are finite fixtures and live samples; not a proof.
