# onto-tests-fixture

The groupant beside onto/src/tests.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:** [`onto/src/tests.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/src/tests.rs)
- **source SHA-256:** `5e6ede24ca951f50…`
- **covers:** Build17 OEWN concepts, sorted words, whale senses[15,8], CSR/transposed edges from fixed arrays; unwrap store::check. (bytes 375–3678)
- **part of:** [onto-tests](https://md.groupants.elamur.ai/free/en/mova/onto/src/tests.rs.groupant/)
- **repository folder:** [`onto/src/tests.rs.groupant/fixture.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/src/tests.rs.groupant/fixture.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 |
|---|---|---|

## 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

#### onto-tests-fixture

Build17 OEWN concepts, sorted words, whale senses[15,8], CSR/transposed edges from fixed arrays; unwrap store::check.

##### Epoch 2026-10-31

Prospective review preceded inline test edits. Tests used bounded synthetic CPU fixtures only. Scope bytes [375,3678) in the parent source. Failed store structural check cannot silently return Graph. Fixture does not cover arbitrary corpus distributions.

No production optimization, live teacher, corpus, assessment or database mutation. Registry presence denotes partial modeling; syntax is lexical and generated twice identically.

### approximant

#### Forward model: onto-tests-fixture

Build17 OEWN concepts, sorted words, whale senses[15,8], CSR/transposed edges from fixed arrays; unwrap store::check.

##### Domain

Finite input arrays/text with resource availability and the source-specific bounds and representation assumptions in [invariant.md](https://md.groupants.elamur.ai/free/en/mova/onto/src/tests.rs.groupant/fixture.groupant/#invariant). Exact categorical semantics; no executable percent surrogate is supplied. 1/2/5/10% caps need a meaningful metric and are not claimed.

##### Relations

Cid(synᵢ)=i; W=sort(unique(lemmas)); Wid(w)=binary_search_W(w). E=IsA∪InstanceOf∪PartOf fixture tuples; reverse(s,r,t)=(t,r,s). sense(whale)=[15,8] overrides default insertion order; check(Graph)=Ok required.

### invariant

## Invariant and cost

Scope bytes [375,3678) in the parent source. Failed store structural check cannot silently return Graph. Fixture does not cover arbitrary corpus distributions.

### Cost

Linear traversed scope input/returned bytes except lookup logarithmic comparisons; allocations follow actual result buffers. Parent whole-pipeline cost is not assigned to this fragment.

No allocation, integer-overflow, malformed public-state or external-effect guarantee beyond explicitly described branches.

### composition

#### Composition

Scope output feeds its parent: Synthetic Graph → store → Kb → query/eval/pron/HS, with explicit fixture-only assertions; core completeness tests exercise parser without real core data.

Child fragments specialize concrete byte scopes and share the parent syntax projection; they do not duplicate whole-file guarantees. No composition-wide approximation error budget is established.

### models

## Typed obernant catalog

Partial source-derived relations, not proofs. Complement excludes incompatible observations; reverse describes compatible antecedents.

### behavior_complement

Failed store structural check cannot silently return Graph. Fixture does not cover arbitrary corpus distributions.

### reverse_reconstruction

Returned arrays admit other construction algorithms sharing same sorting/order; source code not invertible.

### sense_ambiguity

Whale person precedes animal to test downstream context reordering.

### coordinates

Cid is syn-list index; Wid sorted word position.

### transpose_fixture

Reverse source/target preserve Rel.

### bounded_domain

Fixed17 concepts; no I/O inside mini.

### tests

#### Evidence, 2026-10-31

Named outcomes:

- tests::hs_isa_gate

Two debug and two release/optimized executions returned zero and identical sorted nonempty named outcomes. Source-generated syntax pairs matched byte-for-byte. No dedicated compiled runtime control for this test-fixture source; production controls are mapped separately.



Finite synthetic examples only. Full ingestion, live workers, real corpus, allocation/I/O fault injection, GPU and full-school behavior remain unexecuted. No universal or executable-approximant assurance. External receipts: octopus-wave29-ontocore-2026-10-31 (native-commands.json, source-test-map.json, outcomes.json, controls.json and numeric exit/log files).

##### Prior isolation correction

Initial repeated query tests omitted ONTO_PRIOR; query ranking may initialize wsd::global_prior from ambient/default path. Whether that file existed was not established; initial query outcomes are not fully isolated evidence. The affected queries_answer_with_proofs_and_refuse_to_guess name was rerun twice debug and twice release with ONTO_PRIOR asserted absent before/after. All four pass. Native command specs now set this environment. See prior-isolation.json.
