Elamur Groupantsmova-elephant-main
The groupant beside tools/elephant/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 elephant command line: the store (init, add, retract, tamp, view, status, compare, lists, plan, reprogram, suspects), English (ask, serve, client) and the loop (work, work-summary). Source: tools/elephant/src/main.rs.
Forward approximant
Dispatch on the arguments; writing store commands and work take STORE/writer.lock; serve and work hold their own singleton locks.
Invariant
Two writers never act on one store at once.
Cost
As the commands it runs.
Composition
Parent: elephant.
Behavior complement
Parses arguments only; no behaviour of its own beyond dispatch and locks. Evidence status: source-derived model with finite checks, not a proof.
Reverse reconstruction
The argv names the command.
Tests
Checks
Exercised by the probes of 2026-11-06 (init, add, tamp, view, compare, suspects, ask, serve, client). These are finite fixtures and measurements; not a proof.

Epoch 2026-11-06
First model, written with the source (the Elephant made incremental and an animal on Mova).
