# onto-coregate

The groupant beside onto/src/coregate.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:** [`onto/src/coregate.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/src/coregate.rs)
- **source SHA-256:** `31631d014f9c0c1c…`
- **repository folder:** [`onto/src/coregate.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/src/coregate.rs.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

| component | label | where |
|---|---|---|
| **approximant** | partial | [approximant](#approximant) |
| **ast** | partial | `syntax.json` |
| **composition** | partial | [composition](#composition) |
| **cost** | partial | [Cost](#cost) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | `model.md` |
| **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) |
| `failure_precedence` | failure_precedence | partial source derived model | [failure_precedence](#failure-precedence) |
| `numeric_cardinality` | numeric_cardinality | partial source derived model | [numeric_cardinality](#numeric-cardinality) |

## Model text


### descriptant

#### onto-coregate

read_core trims columns and validates domain. Property rows check width20→membership→field→status→synset consistency, group into maps, then check completeness by core and FIELDS order, homogeneous status, none-only-risk, singleton known number.

##### Epoch 2026-10-31

Prospective review preceded inline test edits. Tests used bounded synthetic CPU fixtures only. Success has every core×11 field and one synset per key; duplicate core entries retained. Empty core/props succeeds; empty unknown reason, numeric values and units unvalidated.

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-coregate

read_core trims columns and validates domain. Property rows check width20→membership→field→status→synset consistency, group into maps, then check completeness by core and FIELDS order, homogeneous status, none-only-risk, singleton known number.

##### 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/coregate.rs.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

Success ⇔ read_core succeeds ∧ every property row passes ordered(width20, member, field, status, consistent_synset) ∧ ∀k∈core,f∈FIELDS: cell(k,f)≠∅ ∧ uniform_status(cell) ∧ (status=none⇒f=risk) ∧ (status=known∧f∈NUMBER⇒|cell|=1). First failing row/predicate determines error before completeness traversal.

### invariant

## Invariant and cost

Success has every core×11 field and one synset per key; duplicate core entries retained. Empty core/props succeeds; empty unknown reason, numeric values and units unvalidated.

### Cost

O(B+RC+11C+R) expected map work, with BTree field lookup factors. O(B+R+C) storage; no allocation-failure Result.

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

### composition

#### Composition

coresel writes 20-column rows consumed by build.rs through this parser. Parsing validates categorical completeness, not f64 finiteness or provenance literals.

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

Success excludes width/member/field/status/synset/cell violations, but not NaN or empty unknown reason.

### reverse_reconstruction

Parsed rows retain within-cell order; comments, blank lines and interleavings between cells are unrecoverable. Core whitespace and extra columns lost.

### failure_precedence

Core domain errors precede all property checks. Row-local errors precede completeness even for earlier missing concept.

### numeric_cardinality

Only known numeric fields require singleton; unknown can have multiple same-status rows.

### risk_state

none is risk-only; known risk action and probability grammar not checked.

### whitespace_domain

Core fields trim; property fields do not. Leading-space # is not a comment; comparisons case-sensitive.

### tests

#### Evidence, 2026-10-31

Selected command: cargo test --offline --locked -p onto --bin onto -- --exact --test-threads=1 coregate::wave29::ordered_gate_and_empty_domain

Named outcomes:

- coregate::wave29::ordered_gate_and_empty_domain

Two debug and two release/optimized executions returned zero and identical sorted nonempty named outcomes. Source-generated syntax pairs matched byte-for-byte. 1 compiled source mutation rejected by named test, exact source restored and positive rerun succeeded.

- Control: "f.len() != 20 -> f.len() != 21" → "coregate::wave29::ordered_gate_and_empty_domain" (exit 101).

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.
