# onto-bridge-world-ingest

The groupant beside onto/src/bridge.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/bridge.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/src/bridge.rs)
- **source SHA-256:** `b9df59904a00c9ad…`
- **covers:** Files→first unique content hash→used filename→typed char/obj/loc lines (bytes 932–2778)
- **part of:** [onto-bridge](https://md.groupants.elamur.ai/free/en/mova/onto/src/bridge.rs.groupant/)
- **repository folder:** [`onto/src/bridge.rs.groupant/world-ingest.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/src/bridge.rs.groupant/world-ingest.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) |
| `field_boundary` | field_boundary | partial source derived model | [field_boundary](#field-boundary) |
| `file_order` | file_order | partial source derived model | [file_order](#file-order) |
| `failure_prefix` | failure_prefix | partial source derived model | [failure_prefix](#failure-prefix) |
| `effect_exclusion` | effect_exclusion | partial source derived model | [effect_exclusion](#effect-exclusion) |

## Model text


### descriptant

#### onto-bridge-world-ingest

Files→first unique content hash→used filename→typed char/obj/loc lines

##### Epoch 2026-10-31

Specialized source fragment bytes [932,2778); shared parent AST. Excludes unrelated parent operations and added test module.

### approximant

#### Scoped forward

Files→first unique content hash→used filename→typed char/obj/loc lines

##### Domain

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

key requires leading space and =; quotes require closing quote

First identical bytes wins tale naming

UTF8 read error returns Err before processing that file

Reads only; no writes to source world

No executable percentage surrogate established.

### invariant

#### Local observations

Missing type excludes Ent; later same-content copy excludes used/entity extension

key requires leading space and =; quotes require closing quote

First identical bytes wins tale naming

UTF8 read error returns Err before processing that file

Reads only; no writes to source world

### cost

#### Scoped cost

O(B) read/hash/line scans across supplied files, O(E) emitted entities and O(U) distinct digest/used records. Entire current file string allocated; duplicate text is still read and hashed. File-read failure stops iteration.

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

### composition

#### Parent join

world-ingest supplies the parent relation: Files→first unique content hash→used filename→typed char/obj/loc lines

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

### models

### behavior_complement

Missing type excludes Ent; later same-content copy excludes used/entity extension

### reverse_reconstruction

Ent preimage permits ignored fields/lines but first unique filename determines tale

### field_boundary

key requires leading space and =; quotes require closing quote

### file_order

First identical bytes wins tale naming

### failure_prefix

UTF8 read error returns Err before processing that file

### effect_exclusion

Reads only; no writes to source world


### 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.
