# sources-library

The groupant beside tools/sources/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

- **kind:** groupant
- **status:** partial source bound model
- **source:** [`tools/sources/src/lib.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/sources/src/lib.rs)
- **source SHA-256:** `80f75f0645a80192…`
- **repository folder:** [`tools/sources/src/lib.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/sources/src/lib.rs.groupant)
- **repository commit:** `48f2e6f74146`

> **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 | [approximant](#approximant) |
| **ast** | partial | `syntax.json` |
| **cost** | symbolic source derived | [invariant-and-cost](#invariant-and-cost) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | [invariant-and-cost](#invariant-and-cost) |
| **tests** | bounded evidence and explicit gaps | [tests](#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](#behavior-complement) |
| `reverse_reconstruction` | reverse_reconstruction | partial source derived model | [reverse_reconstruction](#reverse-reconstruction) |
| `symbol_transport` | symbol_transport | partial source derived model | [symbol_transport](#symbol-transport) |
| `visibility_boundary` | visibility_boundary | partial source derived model | [visibility_boundary](#visibility-boundary) |
| `dependency_identity` | dependency_identity | partial source derived model | [dependency_identity](#dependency-identity) |
| `consumer_projection` | consumer_projection | partial source derived model | [consumer_projection](#consumer-projection) |

## Model text

The model text names local infrastructure and is not shown here; read it in the [open repository](https://github.com/ElamurAI/mova-free/blob/main/tools/sources/src/lib.rs.groupant/model.md).
