# world-tests03-spatial

The groupant beside world/src/tests03.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_fragment
- **status:** partial source bound model
- **source:** [`world/src/tests03.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/tests03.rs)
- **source SHA-256:** `8b5c69135919d359…`
- **covers:** Assert recognized lexical arrangements, three None cases, equivalent renamed above phrases, unequal below phrase, and two corrected-format items with second story length two. (bytes 555–2384)
- **part of:** [world-tests03](https://md.groupants.elamur.ai/free/en/mova/world/src/tests03.rs.groupant/)
- **repository folder:** [`world/src/tests03.rs.groupant/spatial.groupant`](https://github.com/ElamurAI/mova-free/tree/main/world/src/tests03.rs.groupant/spatial.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.

## 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 |

## Model text


### descriptant

#### world-tests03-spatial

Assert recognized lexical arrangements, three None cases, equivalent renamed above phrases, unequal below phrase, and two corrected-format items with second story length two.

##### Modeling epoch — 2026-10-31

Read full assigned source before editing; prospective predictions retained in external wave29 receipts. This child binds only its stated half-open UTF-8 byte range; other APIs remain parent scope. Evidence is limited to named bounded fixtures; registration is partial modeling. Production behavior unchanged; only inline synthetic tests added to four assigned sources.

### approximant

#### Forward relation

Assert recognized lexical arrangements, three None cases, equivalent renamed above phrases, unequal below phrase, and two corrected-format items with second story length two.

##### Domain and resource limits

Finite valid structures and allocation-success executions under the branch conditions in models.md; integer overflow is outside measured fixtures. Exact categorical relations have no supplied percent surrogate. Macro expansion, arbitrary model quality and external effects are not inferred from syntax.

### invariant

## Invariant

Actual helpers on literals; no Reader training/dataset load.

### Cost

Fixed text; lexical/normalization costs delegated.

### composition

#### Composition

This scope contributes spatial to its parent. Its forward, complement and preimage are restricted to the bound byte interval. The parent syntax projection is referenced once through ../syntax.json; no independent semantic AST is claimed.

### models

### behavior_complement

Exclude equal normalized above/below and definite clock/conflict/directionless vectors; second story cannot contain prior O-Z line.

### reverse_reconstruction

Equal phrases leave original letters unknown; story length two admits many texts and erased support values.

### reverse_frame

Z has Q on its left => Z-relative-Q right.

### origin_frame

From Z down/right to Q => Z-relative-Q (-1,1).

### overlap

coincide gives zero; waits gives None.

### reset

Second numbered1 resets, then two statements precede question.

### tests

#### Bounded checks

Named checks associated with this source (not every fragment branch):

- tests03::stepgame_lexical_reader_reads_new_phrasings
- tests03::stepgame_phrasing_and_corrected_format
- tests03::narrower_variants_and_scoped_changes

17 unique named tests in total passed twice debug and twice release; sorted named outcomes equal across all four runs. Four compiled controls cover bAbI identity, StepGame tie ordering, parser-command state removal and bench-command CPU selection; each exits101 at a runtime assertion, exact source restored then positive exit0. Other sources have finite adversarial fixtures but no separately compiled mutant.

CLI integration coverage is command construction and temporary cleanup only; legacy school/model/cadence paths are not executed. No speed benchmark, GPU, live teacher, datasets or held-out replay.

Limits:

- Only three selected tests; no remaining grammar/social/calendar runtime coverage
- Executable percent approximant unsupported for exact assertions
