# world-ans-ranking-score-priority

The groupant beside world/src/ans.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/ans.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/ans.rs)
- **source SHA-256:** `d8d94c891e347d2b…`
- **covers:** Exclusive lexical evidence priority (bytes 22804–23153)
- **part of:** [world-ans-ranking](https://md.groupants.elamur.ai/free/en/mova/world/src/ans.rs.groupant/ranking.groupant/)
- **repository folder:** [`world/src/ans.rs.groupant/ranking.groupant/score-priority.groupant`](https://github.com/ElamurAI/mova-free/tree/main/world/src/ans.rs.groupant/ranking.groupant/score-priority.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.

## 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


Wave34, 2026-10-31. Subject: world-ans-ranking-score-priority, current source SHA d8d94c891e347d2b640744b20c4662dc35064368e7d4d9253c4954b4297e1e09. Domain: one terminating supplied-input helper transition; valid indices, sufficient memory and finite strings/trees/worlds. Source-derived partial relations, not a verified universal theorem. All views below share this domain and exact manifest scope; specialized assumptions are stated locally. No executable percentage approximant is claimed.

### forward

For each query lemma class choose first overlap: event verb +3 and vhit=true, else participant +1.5, else text +1, else zero. Sum independently for repeated query classes.

### invariant

A class matching all fields contributes 3, not 5.5; vhit cannot be true without a verb overlap.

### behavior-complement

A class matching all fields contributes 3, not 5.5; vhit cannot be true without a verb overlap.

### reverse-reconstruction

For one class and score=3/vhit=true, all four participant/text membership assignments with verb=true are compatible. Aggregate scores lose assignment and query-order information; retain every class sequence producing both score and vhit.

### parent-interaction

ev_words constructs lexical classes before this helper; find_events_min receives both numeric score and vhit, and must retain the distinction.

### boundary

Duplicate query classes count repeatedly; duplicate alternatives inside a class do not multiply the existential overlap.

### information

Once verb matches, adding text or participant alternatives preserves this class contribution; moving text to verb can increase score.

### cost

O(sum over query classes of examined lexical alternatives times query-class membership length); early branch matches avoid lower fields.

### checks

Existing eight-mask priority/fiber test calls actual score_words without dictionary lookup.

Exact selected native boundary: `cargo test --offline --locked -p world --lib ans::wave8_models::score_precedence_and_fibers -- --exact --test-threads=1`. Repeated in debug and release; see the current file-level wave34 evidence and external native-receipts.json.

### assurance

The behavior-complement is an inner exclusion hypothesis over admissible input/output pairs, derived from branch order; not the complement of an incomplete model of the entire file. Reverse reconstruction is the compatible antecedent relation, retaining every modeled ambiguity rather than a chosen inverse. Parent-interaction is a composition relation, boundary a constraint relation, information an information/state projection, and cost a resource relation. The named checks are finite falsifiers; unexecuted branches remain source-inspected gaps. No parser/model/teacher/corpus/frozen assessment was run.

### epoch-memory

New child in wave34; no prior child renamed or counted. Parent historical wave8/wave9 evidence remains historical. Current raw receipts are in the external wave34 reasoning run; source syntax is partial, macros opaque, and no semantic AST or general proof is supplied.
