Elamur Groupantsmova-nautilus-lib
The groupant beside tools/nautilus/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 |
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
model
mova-nautilus-lib
Descriptant
Crate root of mova-nautilus: declares animal, layer, sources, teacher and work. Source: tools/nautilus/src/lib.rs.
Forward approximant
Expose the modules.
Invariant
Only module declarations.
Cost
O(1).
Composition
Parent: nautilus. Root of the library used by main, the tests and mova-turtle. State: None.
behavior_complement
Holds no behaviour of its own. 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.
Epoch 2026-11-04
First model, written with the source; no prospective prediction is claimed beyond the checks.
Epoch 2026-11-04 (pool)
modules improve (the layer source) and pool (a Crab pool member).
Epoch 2026-11-04 (pool)
modules improve (the layer source) and pool (a Crab pool member).
Epoch 2026-11-04 (senses)
Declares senses and replay.
tests
Checks
Command: cargo test --manifest-path tools/nautilus/Cargo.toml --offline --locked with MOVA_OCTOPUS_TEST_MODEL=$MOVA_DATA/download/0/0.4/en.bin (15 unit + 2 English tests; two identical runs on 2026-11-04).
Negative controls 2026-11-04 (each red, restored): no operator-word check; no terminal-id check; a limit not stopping the loop; stats drafting instead of reading. These are finite fixtures; no teacher or model was called; not a proof.
Pool epoch (2026-11-04): cargo test --release with the 0.4 en.bin, 26 unit + 2 English tests, two identical runs; red controls in the pool, improve and sources tests (each red, restored). Finite fixtures, not a proof.
2026-11-04 (senses): cargo test --release (0.4 en.bin), tools/nautilus 37 unit + 2 English tests, two identical runs; tools/turtle 9 + 2 pass.
