Elamur Groupantsmova-turtle-gap-tests
The groupant beside tools/turtle/tests/gap.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 |
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.

Model text
Descriptant
The gap maker on real data with the 0.4 model and Open English WordNet: red controls on the sentences of 2026-11-04 whose wrong options also fitted (only/just, mum/parent, now/out/just/still, go/say/stay/stop), and the repository's commands dictionary layer made into lessons that keep the school's rule with none of those pairs as a wrong option, twice identically. Source: tools/turtle/tests/gap.rs.
Forward approximant
Lex::load(layer words) + slot_of(annotator) → judge and wrong_options on six sentences; gap_lessons(commands layer) → check::lesson and world::knowledge::parse per lesson; second run equal.
Invariant
Deterministic for a fixed model, WordNet and layer.
Cost
One model load and one WordNet load per test (seconds).
Composition
Parent: turtle. Exercises fit, make and check together.
behavior_complement
Skips without MOVA_OCTOPUS_TEST_MODEL; no network or teacher. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
Assertion messages name the sentence, the answer and the option. No unique inverse is claimed.
Epoch 2026-11-04
First model, written with the source; red with the fit check switched off (negative control).
tests
Checks
Command: cargo test --manifest-path tools/turtle/Cargo.toml --offline --locked with MOVA_OCTOPUS_TEST_MODEL=$MOVA_DATA/download/0/0.4/en.bin and Open English WordNet under $MOVA_DATA/raw/en-oewn/json (14 unit + 2 English + 2 gap tests; two identical runs on 2026-11-04).
Negative controls 2026-11-04 (each red, restored): check without the school's rule; held-out course names read; the deputy vocabulary without «command»; the fit check switched off (4 unit and both real-data gap tests red: «just» for «only», «dad» for «mum»); the sweep reading held-out courses; a teacher step after a sweep that closed lessons. Red controls kept in the tests: only/just and mum/parent refused as near-synonyms, now/out/just and go/say as words that fit the gap. These are finite fixtures; no teacher was called; not a proof.
