Elamur Groupantsmova-topic-corpus-lib
The groupant beside tools/topic-corpus/src/lib.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
Crate root of mova-topic-corpus: module list and the crate's purpose (topic graphs and closed topic corpora for the paper-describing Whales). Source: tools/topic-corpus/src/lib.rs.
Forward approximant
Declares the modules graph, missing, corpus, seed, web, cite, sol, world, hardcases, library, licence, config; re-exports anyhow::Result.
Invariant
No logic; every public module is listed once.
Cost
O(1).
Composition
Parent: topic-corpus.
behavior_complement
No behaviour of its own; does not re-export Whale or Sea Spider types. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
The module list is recoverable from the source; nothing else. No unique inverse is claimed.
tests.md
Compiled by every test of the crate.
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.
