Elamur Groupantsmova-nightingale-main
The groupant beside tools/nightingale/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.
| 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 mova-nightingale command line: count, count-units, count-into, build, dev, handoff, measure, judge, signals, status, ask, serve, client, work, work-summary and round. Source: tools/nightingale/src/main.rs.
Forward approximant
argv -> one command -> JSON or English on stdout; serve takes a singleton lock; work takes the work lock; round parses the Eel's child arguments.
Invariant
One serve per lock, one loop per work folder; an unknown command prints the usage and fails.
Cost
Dominated by the command it runs.
Composition
Parent: nightingale.
Behavior complement
Starts nothing by itself; never retries a failed step. Evidence status: source-derived model with finite checks, not a proof.
Reverse reconstruction
The command line and the journals (work.jsonl, english.jsonl) recover what was run.
Tests
Checks
Used by the probes of 2026-11-06 (count, handoff, measure, judge, signals, work). 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).
