# module-overlay-fixtures

The groupant beside tools/module-overlay/src/tests.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/module-overlay/src/tests.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/module-overlay/src/tests.rs)
- **source SHA-256:** `6eda2bb6500b185d…`
- **repository folder:** [`tools/module-overlay/src/tests.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/module-overlay/src/tests.rs.groupant)
- **repository commit:** `855da7bd4a7b`

> **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** | source derived partial | [forward](#forward) |
| **ast** | partial | `syntax.json` |
| **cost** | source derived partial | [cost](#cost) |
| **descriptant** | present | [epoch-memory](#epoch-memory) |
| **invariant** | source derived partial | [invariant](#invariant) |
| **tests** | bounded native evidence | [checks](#checks) |

## 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 |
|---|---|---|---|
| `module-overlay-fixtures-behavior-complement` | behavior_complement | partial source model | [behavior-complement](#behavior-complement) |
| `module-overlay-fixtures-reverse-reconstruction` | reverse_reconstruction | partial source model | [reverse-reconstruction](#reverse-reconstruction) |
| `module-overlay-fixtures-oracle-independence` | finite_oracle_partition | partial source model | [oracle-independence](#oracle-independence) |
| `masked-drift-oracle-partition` | finite_oracle_partition | finite native debug release and red control | [masked-drift-oracle-partition](#masked-drift-oracle-partition) |

## 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/module-overlay/src/tests.rs.groupant/model.md).
