Elamur Groupantsmova-nightingale-animal
The groupant beside tools/nightingale/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.
| relation | 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 Nightingale as an animal: its configuration and checks, the deputy's hands (status, proposals), the service that holds annotators, model, contrast and lists, and the English answer path. Source: tools/nightingale/src/animal.rs.
Forward approximant
Config::load -> check; model_dir: installed first, else newest handoff; Service::open; answer: reader first, deputy with hands otherwise; journal english.jsonl.
Invariant
The English service only observes; a source of another language is refused; machine paths stay out of public examples.
Cost
Service open: annotators and the model loaded once.
Composition
Parent: nightingale.
Behavior complement
Never writes a model or a list. Evidence status: source-derived model with finite checks, not a proof.
Reverse reconstruction
english.jsonl keeps each question's hash, reader and frame.
Tests
Checks
animal::tests; tests/english.rs. These are finite fixtures and measurements; not a proof.
History

Epoch 2026-11-06
First model, written with the source (the Nightingale: one per language under the Eel; a standard naturalness model with variety deltas).
