Elamur Groupantsmova-whale-world-tests
The groupant beside tools/whale-world/src/tests.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
End-to-end tests of dossier -> world -> query on three small documents (two GEC papers, one unrelated, a CC0 page): byte-identical builds, licence of world texts, GEC entity and definition, explanations, citations resolving to documents and sentences, related and neighbourhood order, neighbourhood content count, byte cut; incremental epochs (old shards untouched, texts.jsonl prefix kept, world(1) unchanged, plain draft read via the heading fallback) and a changed file refused with nothing written. Source: tools/whale-world/src/tests.rs.
Forward approximant
build twice -> compare every file -> queries -> asserts; add epoch-1 text -> add(1) nothing -> add(2) one -> compare files -> views -> change a file -> add(3) refused, store unchanged.
Invariant
Model-dependent tests skip without WORLD_EN_MODEL.
Cost
About 1 s with the model.
Composition
Parent: whale-world; cfg(test) only.
behavior_complement
Does not test the library graph edges or real corpora (fixtures have no library); not a proof. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
Not applicable beyond the fixtures, which are rebuilt in each run.
tests.md
cargo test --manifest-path tools/whale-world/Cargo.toml --offline with WORLD_EN_MODEL=$MOVA_DATA/download/0/0.4/en.bin (9 unit tests: dossier append-only/select/changed files, licence negative controls, citation markers, importers incl. a topic corpus with a Sea Spider page and a consultant draft, entity extraction, LRU, two byte-identical world builds with cited queries, incremental epochs with old worlds intact and a changed file refused; 2026-11-05). Live 2026-11-05 on six papers: two independent imports and builds byte-identical.
These are finite fixtures and live samples; not a proof.
