# latex-table

The groupant beside latex/src/table.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:** [`latex/src/table.rs`](https://github.com/ElamurAI/mova-free/blob/main/latex/src/table.rs)
- **source SHA-256:** `37b46b94914c5c15…`
- **repository folder:** [`latex/src/table.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/latex/src/table.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` |
| **composition** | partial | [composition](#composition) |
| **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) |
| `class_projection` | class_projection | partial source derived model | [class_projection](#class-projection) |
| `negation_preimage` | negation_preimage | partial source derived model | [negation_preimage](#negation-preimage) |
| `font_subset` | font_subset | partial source derived model | [font_subset](#font-subset) |
| `generated_binding` | generated_binding | partial source derived model | [generated_binding](#generated-binding) |

## Model text


### descriptant

#### latex-table

Class::latex merges Ord/Fence and operator-family classes; include consumes build output. negated matches a fixed partial symbol map; Le and Leqslant both become Nleq. font_letter recognizes only seven double-struck capitals and returns Latin base.

Epoch2026-10-31: full source reviewed before edits; prospective models retained externally. No optimization.

### approximant

#### Forward relation

Class::latex merges Ord/Fence and operator-family classes; include consumes build output. negated matches a fixed partial symbol map; Le and Leqslant both become Nleq. font_letter recognizes only seven double-struck capitals and returns Latin base.

No useful approximate executable metric for exact categorical syntax; future caps1/2/5/10% only.

### invariant

#### Domain, invariant and cost

Class::latex merges Ord/Fence and operator-family classes; include consumes build output. negated matches a fixed partial symbol map; Le and Leqslant both become Nleq. font_letter recognizes only seven double-struck capitals and returns Latin base.

Enum validity comes from compiler; unknown command/env/character returns None. No numerical approximate metric appropriate.

Fixed dispatch costs per lookup; generated arrays constant index; code size proportional to compiled command table. No runtime table file reads.

### composition

#### Composition

Class::latex merges Ord/Fence and operator-family classes; include consumes build output. negated matches a fixed partial symbol map; Le and Leqslant both become Nleq. font_letter recognizes only seven double-struck capitals and returns Latin base.

Build generates table enums consumed by parser dispatch and printers. Lexer tokens feed macros and parser; parser returns AST whose equality ignores spans. Printers and gate compare that quotient, not original bytes. Shared parent syntax backs scoped stages; stages are byte-bound projections, not independent Rust modules.

### models

### behavior_complement

Unsupported negations and nonlisted font letters return None rather than invented symbol mappings; negation is not involutive.

### reverse_reconstruction

Preimage of Nleq contains Le and Leqslant; preimage of mathop contains Op, OpNoLim, Fn, FnLim. Generated alias lookups admit multiple spellings for one enum.

### class_projection

Class::latex deliberately merges operator families and Fence with Ord.

### negation_preimage

Distinct source symbols can map to same negation; absent mapping is None.

### font_subset

Only C,H,N,P,Q,R,Z double-struck capitals map to Font::Bb.

### generated_binding

include OUT_DIR/table.rs binds variants, canonical arrays and lookup matches from one build.

### tests

#### Evidence — 2026-10-31

table::tests::table_lookups; table::tests::every_negation_is_a_relation_or_ord

Selected library filters ast:: lex:: macros:: parse:: print:: table:: and integration gate excluding document_extraction_with_preamble_macros and random_token_soup_never_panics_and_roundtrips. Direct rustc --test latex/build.rs exercises private helpers. All selected tests twice debug/release with identical sorted names. Four compiled mutants at build/AST/parser/printer boundaries fail assertions then exact restoration passes. These do not individually cover every source. Build-main failure effects, allocation failures and universal roundtrip are unproved. Strict Clippy reports existing lints. No corpus/live VMM/API/GPU/full-school/held-out tests.
