# world-babi-questions

The groupant beside world/src/babi.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/babi.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/babi.rs)
- **source SHA-256:** `54596da093fa9515…`
- **covers:** Three-word identity shortcut precedes self rewrite and parser. Extract known longest noun phrases then ordered branches. Where-before uses latest matching history target; what/who scans latest relations before carry/transfers/class inference. (bytes 29782–44995)
- **part of:** [world-babi](https://md.groupants.elamur.ai/free/en/mova/world/src/babi.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) |

## 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

#### world-babi-questions

Three-word identity shortcut precedes self rewrite and parser. Extract known longest noun phrases then ordered branches. Where-before uses latest matching history target; what/who scans latest relations before carry/transfers/class inference.

##### 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

Three-word identity shortcut precedes self rewrite and parser. Extract known longest noun phrases then ordered branches. Where-before uses latest matching history target; what/who scans latest relations before carry/transfers/class inference.

##### 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

Self identity needs no annotator. At/Not/Either give distinct yes-no uncertainty; count entries 0..6 map none..six, greater counts many.

### Cost

Identity O(question bytes), parser delegated; entity matching and reverse scans plus O(HlogH) history sort.

### composition

#### Composition

This scope contributes questions 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 named Who-are-you when me=None, or latest attribute from an empty list. No completeness guarantee for arbitrary questions.

### reverse_reconstruction

Self-answer n constrains me but not histories. Where-before x admits histories whose last target has predecessor x. Latest class attribute admits minority votes because recency, not majority, wins.

### query_precedence

how+from precedes how+many; relation what/who precedes carry/transfer.

### uncertainty

Not target→no, other→maybe; Either member→maybe, nonmember→no; absent→?.

### attribute_recency

Most recent peer attribute wins regardless of majority.

### resources

General ask uses parser and recursive rewrite; Unicode byte recasing risk unexecuted.

### tests

#### Bounded checks

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

- babi::wave29_tests::identity_and_inventory_without_parser
- babi::wave29_tests::graph_and_sentence_boundaries_without_parser

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:

- Partial syntax projection only; no macro expansion or proof
- No useful percentage surrogate for exact categorical/state/effect semantics; executable approximant unsupported
- No live parser, corpus, gap journal, training or held-out evaluation
- Unicode recasing byte slices, unbounded recursion/overflow not covered
