Source: `tools/nautilus/src/animal.rs`. ### Forward approximant Config::load validates sources, paths and top; make: read base, read and annotate the source, layer::build, render, write out, stats; stats: read out or not made; Hands: operation from trusted parameters -> make/stats + English sentence; answer: Deputy::run_with with Hands, report(); singleton: try_lock on LOCK, pid written, else 'already running as pid N'. ### Invariant One handler per configured operation and layer; a second serve on the same lock never starts. ### Cost make: as layer and sources; stats: O(layer bytes). ### Composition Parent: `nautilus`. Parent: nautilus. State: Layer files, deputy ledger, lock file. ### behavior_complement No slots, no teacher calls, no file other than the configured layer is written; a refused prompt does nothing. Evidence status: source-derived model with finite checks, not a proof. ### reverse_reconstruction From the deputy ledger: prompt, plan and outputs per request id; from the layer file its counts. 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) sources `course` (course folders) and `layer` (an existing layer improved through proposals; no `out`); `licence_class` and `shipped` enforced by LayerConfig::check (CC BY-SA, NC, research-only never in a shipped layer; Wikipedia is always cc-by-sa) and check_inputs (a CC BY-SA header in a lesson or the layer file refuses a shipped layer); Config::job builds a LayerJob or a DictJob for part of parts; stats of an improved layer report weak, askable, thin rows and teacher questions. Red controls: licence check removed; header check removed; layer folder not frozen. ### Epoch 2026-11-04 (pool) sources `course` (course folders) and `layer` (an existing layer improved through proposals; no `out`); `licence_class` and `shipped` enforced by LayerConfig::check (CC BY-SA, NC, research-only never in a shipped layer; Wikipedia is always cc-by-sa) and check_inputs (a CC BY-SA header in a lesson or the layer file refuses a shipped layer); Config::job builds a LayerJob or a DictJob for part of parts; stats of an improved layer report weak, askable, thin rows and teacher questions. Red controls: licence check removed; header check removed; layer folder not frozen. ### Epoch 2026-11-04 (senses) Config gains `senses` (the shared sense store path), `batch` (1..40 words per question, default work::BATCH 25) and `pacing_secs` (>= 30, default 600); Config::job passes batch and the store to LayerJob and DictJob. Unknown fields are still refused (an old binary refuses a configuration with the new fields). ### 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.
