# latex-corpus-outputs

The groupant beside latex/src/corpus.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:** [`latex/src/corpus.rs`](https://github.com/ElamurAI/mova-free/blob/main/latex/src/corpus.rs)
- **source SHA-256:** `ae16662c288257b4…`
- **covers:** report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files. (bytes 10109–15398)
- **part of:** [latex-corpus](https://md.groupants.elamur.ai/free/en/mova/latex/src/corpus.rs.groupant/)
- **repository folder:** [`latex/src/corpus.rs.groupant/outputs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/latex/src/corpus.rs.groupant/outputs.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

## 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.

## Model text


### descriptant

#### latex-corpus-outputs

report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files.

Epoch 2026-10-31: complete sources read before tests/model edits. Partial source-bound modeling; no production optimization or speed claim. Nested fragments share the parent lexical syntax. Caller/callee contracts outside owned files remain delegated.

### approximant

#### Forward relation

report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files.

#### Domain and executable surrogate gap

Bounded UTF-8 inputs and synthetic local files; supported parser-produced trees and representable arithmetic. Arbitrary public constructors are not certified total. Exact categorical semantics lack a useful percentage surrogate; no executable approximant attachment. Future numerical profiles require an explicit metric, zero case, source/evidence binding and supported 1/2/5/10% cap. Failure/effect differences cannot count as numerical error.

### invariant

#### Invariant

For the scoped transition bytes [10109,15398): report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files. Empty bridge sample vector excludes new sample write, but stale sample file may remain; no atomic output.

#### Cost

Sort unknown/error keys O(K log K), generate and write report/table bytes; partial filesystem effects.

Allocation failure, stack exhaustion and unchecked counter overflow have no additional certificate. No timing claim or global error bound.

### composition

#### Composition

report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files.

For the scoped transition bytes [10109,15398): report rounds percentages/durations; unknown/reasons sort count then name, errors count only. write_tables serially replaces output files. Empty bridge sample vector excludes new sample write, but stale sample file may remain; no atomic output.

Parser, printer, AST equality, Macros, Rat and evaluator dependencies retain their own contracts. Structural roundtrip is not arithmetic definedness or numeric truth. Exact lexical binding does not prove caller/callee semantics.

### models

### behavior_complement

Empty bridge sample vector excludes new sample write, but stale sample file may remain; no atomic output.

### reverse_reconstruction

Equal reports permit different omitted samples, hash identities and rounded durations; normalized examples lose whitespace.

### zero

pct(a,0)=0; seconds clamp1e-9.

### ranking

Error ties lack lexical key.

### failure

I/O error leaves earlier replacements.

### display_loss

Examples normalize whitespace and visible unknown samples truncate70 chars.


### tests

#### Selected evidence

cargo test -p latex --features math --bin latex wave28

Two debug/two release executions retained matching sorted named outcomes. External wave28 latexbridge receipts retain numeric exits, compiled assertion controls, restoration, feature checks and source-test map. This scope is not exhaustive branch coverage; parent tests may only exercise some child transitions. Frozen VMM DATA/classification/hash subprocess, live corpus, teacher/API, training/GPU excluded. Reexport/feature compilation is separate from runtime semantics.
