# kg-uk-render

The groupant beside kg/src/uk.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 SHA-256:** `f2c9f7b2877f239a…`
- **covers:** Per-member synthesis and normalized multiset completeness. (bytes 25347–26679)
- **part of:** [kg-uk](https://md.groupants.elamur.ai/free/en/mova/kg/src/uk.rs.groupant/)

> **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


### descriptant

#### kg-uk-render

Per-member synthesis and normalized multiset completeness.

##### Modeling epoch — 2026-10-31

Source read before tests and models; retained prospective notes accompany the parent. Current evidence uses bounded invented inputs only. This is partial modeling, not proof or corpus accuracy.

### approximant

#### Forward relation

Tokenize text words; skip implicit members; lookup lemma/grammar without NEG; require original indexed normalized form among synth variants; append restored relation prep/quantity and negation; sort and compare.

##### Executable approximant gap

Exact categorical structure, identifiers, parser decisions and effects have no useful percentage metric established here. No executable surrogate, automatic substitution or 1/2/5/10% guarantee is claimed.

### invariant

#### Invariant and domain

Success equates normalized word multiplicities, not order/semantic role.

##### Cost and resources

O(B+sum variant bytes+W log W), O(W) strings.

### cost

#### Cost and resources

O(B+sum variant bytes+W log W), O(W) strings.

### composition

#### Composition

Per-member synthesis and normalized multiset completeness.

Tokenize text words; skip implicit members; lookup lemma/grammar without NEG; require original indexed normalized form among synth variants; append restored relation prep/quantity and negation; sort and compare.

The parent invokes scoped transformations through the actual functions named in their source ranges. Children partition useful observations, not a complete semantic proof; boundaries can omit helpers, tests and effects.

### models

### behavior_complement

Missing synthesis precedes missing-word error; incompatible form precedes multiset mismatch. No implicit word is required.

### reverse_reconstruction

Same successful word multiset admits permutations and spelling variants; word positions constrain individual member lookups but not semantic labels.

### neg_transport

Mask NEG for lookup; append не once per flagged explicit member.

### relation_words

adverbial:prep+case reconstructs prep; quantity:q reconstructs q; arbitrary other relation carries no extra word.

### index_domain

None errors after synth lookup; out-of-range gets empty original string.

### correctness_gap

A damaged/lost member fails fixture; passing check does not prove correct subject/object attachment.


### tests

#### Evidence

Parent source checks (a fragment inherits only the behavior they actually exercise):

- uk::tests::tokens_strip_stress_and_keep_apostrophes
- uk::tests::render_check_catches_damage
- uk::wave29::failure_precedence_and_real_parse

Selected kg tests: 15 named outcomes, twice debug/twice release, equal sorted outcomes. Standalone actual global/build.rs: 3 named outcomes per run, twice debug/twice optimized; build_child is normally no-op, parent fixture invokes it against isolated synthetic seeds. Eight compiled source mutations (one per source) each compiled successfully and exited101 on the focused assertion; exact source restoration followed by positive rerun.

This fragment's untested branches remain source-derived. No live graph, DB, corpus, teacher, GPU or held-out evaluation was used. Command specs and numeric exits are retained in the external wave29 graphlang receipt. Strict kg Clippy reports existing source lints; see receipt.
