Elamur Groupantsmova-turtle-animal
The groupant beside tools/turtle/src/animal.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.
| 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
Sea Turtle as one of Mova's animals: configuration (journal, drafts, layers, courses, the annotator model for gap slots), English answers for check/made/gap, deputy capability check, the turtle handler and answer through the deputy. Source: tools/turtle/src/animal.rs.
Forward approximant
Hands: check -> check::course + say_check; made -> make::made + say_made; gap -> make_gap_course(model from the configuration; refused without one) into drafts/<course>-<invocation> + say_gap; answer: Deputy::run_with with Hands, nautilus::animal::report.
Invariant
Operations and their course or layer come from trusted parameters only.
Cost
As the called functions.
Composition
Parent: turtle. Parent: turtle. State: Journal and drafts.
behavior_complement
No slots; no teacher calls; no course file is written. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
The deputy ledger recovers prompt, plan and outputs per request. No unique inverse is claimed.
Epoch 2026-11-04
First model, written with the source; no prospective prediction is claimed beyond the checks.
Epoch 2026-11-04 (model field)
The configuration takes an optional model; the gap operation refuses to run without it rather than make options without a slot check.
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.
