# mlab-suite-parse-check

The groupant beside mlab/src/suite.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:** [`mlab/src/suite.rs`](https://github.com/ElamurAI/mova-free/blob/main/mlab/src/suite.rs)
- **source SHA-256:** `9f7b9b196ad8e83e…`
- **covers:** Scenario text normalization and line comparator. (bytes 499–3525)
- **part of:** [mlab-suite](https://md.groupants.elamur.ai/free/en/mova/mlab/src/suite.rs.groupant/)
- **repository folder:** [`mlab/src/suite.rs.groupant/parse-check.groupant`](https://github.com/ElamurAI/mova-free/tree/main/mlab/src/suite.rs.groupant/parse-check.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](#invariant) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | [invariant](#invariant) |
| **tests** | executed bounded checks | [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) |
| `blank_line` | blank_line | partial source derived model | [blank_line](#blank-line) |
| `delimiter` | delimiter | partial source derived model | [delimiter](#delimiter) |
| `missing_header` | missing_header | partial source derived model | [missing_header](#missing-header) |
| `first_mismatch` | first_mismatch | partial source derived model | [first_mismatch](#first-mismatch) |

## Model text


### descriptant

#### mlab-suite-parse-check

Scenario text normalization and line comparator.

##### Epoch 2026-10-31

Half-open source bytes [499,3525); bound by parent source hash and scoped byte hash. Model covers only this fragment; parent composition explains joins.

### approximant

#### Scoped forward relation

Headers split on | (first three only); code ends at exact ---; expectations recognize >*, > and > text. Compare exact/prefix, return earliest mismatch.

##### Domain and gap

Source-generated states within resource limits. Categorical relation has no executable percent surrogate.

### invariant

#### Scoped invariant

got empty has no lines; got LF has one empty line.

##### Cost

Linear text and output/expectation traversal, allocating scenario/code/line vectors. String prefixes cost compared bytes; mismatch short-circuits.

### models

## Scoped typed relations

### behavior_complement

Preamble without header excludes scenarios. Prefix matching excludes extra output lines. Comparator mismatch excludes matching any later line as a replacement for the first error.

### reverse_reconstruction

Different ignored preambles and extra header fields map to same scenario; prefix ab accepts abc and ab.

### blank_line

got empty has no lines; got LF has one empty line.

### delimiter

Whitespace around --- prevents delimiter recognition.

### missing_header

Text without ### header returns zero scenarios.

### first_mismatch

Comparison stops earliest mismatch and reports k+1.


### tests

#### Evidence scope

Parent selected tests: wave30_synthetic_suite_boundaries, wave30_synthetic_gate_fail_fast. This fragment shares parent syntax and finite checks; no separate test count or complete fragment coverage claim. Assertion-control association and unexecuted paths are in parent tests.md and source-test-map.json.
