Elamur Groupantsmova-turtle-main
The groupant beside tools/turtle/src/main.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
The turtle CLI: check, gap, made, lesson-task, work, work-summary, work-resume, plan, serve (singleton), ask. Source: tools/turtle/src/main.rs.
Forward approximant
Parse argv -> the matching library call (gap takes MODEL, the en.bin that reads the slots; work takes STEPS, SECS (30) and BATCH (500) and runs turtle::work::run); serve and work take their singleton locks first (exit 5 when held); work plugs the profile's own mova-terminal (Unplugged when its profile is unreadable); no question without the operator's word.
Invariant
Exit status 0 only on success.
Cost
As the called functions.
Composition
Parent: turtle. Parent: turtle. State: None of its own.
behavior_complement
No command calls a model; check fails on any problem. Evidence status: source-derived model with finite checks, not a proof.
reverse_reconstruction
Argv and printed JSON recover what was asked. 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 (pool loop API)
Implements Job::open (lessons left, held-out courses never counted) and passes the pool fields ledger: None, member to Loop; build was broken on main by the Nautilus pool change.
Epoch 2026-11-04 (bulk sweeps)
work runs the Turtle's own loop (work::run: native sweeps without a pause, teacher steps paced); gap needs the annotator model.
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.
