# onto-hs-chunks

The groupant beside onto/src/hs.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/hs.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/src/hs.rs)
- **source SHA-256:** `92e3961f025bb2d0…`
- **covers:** (tokens,exclude,cont,level)→ordered branch features; parenthesis restores exclude/cont (bytes 31095–54284)
- **part of:** [onto-hs](https://md.groupants.elamur.ai/free/en/mova/onto/src/hs.rs.groupant/)
- **repository folder:** [`onto/src/hs.rs.groupant/chunks.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/src/hs.rs.groupant/chunks.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) |
| **ast** | partial | `../syntax.json` |
| **composition** | partial | [composition](#composition) |
| **cost** | partial | [cost](#cost) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | [invariant](#invariant) |
| **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) |
| `continuation` | continuation | partial source derived model | [continuation](#continuation) |
| `negation` | negation | partial source derived model | [negation](#negation) |
| `main_selection` | main_selection | partial source derived model | [main_selection](#main-selection) |
| `level_boundary` | level_boundary | partial source derived model | [level_boundary](#level-boundary) |

## Model text


### descriptant

#### onto-hs-chunks

(tokens,exclude,cont,level)→ordered branch features; parenthesis restores exclude/cont

##### Epoch 2026-10-31

Specialized source fragment bytes [31095,54284); shared parent AST. Excludes unrelated parent operations and added test module.

### approximant

#### Scoped forward

(tokens,exclude,cont,level)→ordered branch features; parenthesis restores exclude/cont

##### Domain

This byte-scoped operator uses the parent valid-state domain plus the following local restrictions:

Bare NP inherits Of/Has/Purpose/Exclude at level

not toggles neg0 except noun-list exclusion

First maximal-level Item else Head

u8 colon depth requires<=255 to avoid overflow

No executable percentage surrogate established.

### invariant

#### Local observations

whether excludes distinguishing feat; excluded nouns cannot become Head/Item

Bare NP inherits Of/Has/Purpose/Exclude at level

not toggles neg0 except noun-list exclusion

First maximal-level Item else Head

u8 colon depth requires<=255 to avoid overflow

### cost

#### Scoped cost

Token index vectors and repeated noun-group/tail scans can take O(T²) time and copying; state vectors O(colon levels), features O(emissions). Parenthesis state cloning adds O(levels) per nested chunk. Recursive tail depth/resource exhaustion unbounded outside finite domain.

Symbolic accounting; no timing claim or whole-system speed bound.

### composition

#### Parent join

chunks supplies the parent relation: (tokens,exclude,cont,level)→ordered branch features; parenthesis restores exclude/cont

Output compatibility is conditional on the local domain and earlier-branch exclusions. Other parent branches are outside this fragment.

### models

### behavior_complement

whether excludes distinguishing feat; excluded nouns cannot become Head/Item

### reverse_reconstruction

Many filler/punctuation variants yield same features with same branch states

### continuation

Bare NP inherits Of/Has/Purpose/Exclude at level

### negation

not toggles neg0 except noun-list exclusion

### main_selection

First maximal-level Item else Head

### level_boundary

u8 colon depth requires<=255 to avoid overflow


### tests

#### Evidence

Parent tests.md identifies selected actual-code checks. Fragment is a source-scoped partial model; parent finite fixtures do not establish exhaustive branch coverage or every local equation.
