# onto-build-script-literals

The groupant beside onto/build.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/build.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/build.rs)
- **source SHA-256:** `439c6f933d542e7a…`
- **covers:** camel concatenates separator-delimited words with ASCII first-letter uppercase; lit Debug-escapes string; fnum parses f64 then Debug-formats. (bytes 1144–1595)
- **part of:** [onto-build-script](https://md.groupants.elamur.ai/free/en/mova/onto/build.rs.groupant/)
- **repository folder:** [`onto/build.rs.groupant/literals.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/build.rs.groupant/literals.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` |

## 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 |

## Model text


### descriptant

#### onto-build-script-literals

camel concatenates separator-delimited words with ASCII first-letter uppercase; lit Debug-escapes string; fnum parses f64 then Debug-formats.

##### Epoch 2026-10-31

Prospective review preceded inline test edits. Tests used bounded synthetic CPU fixtures only. Scope bytes [1144,1595) in the parent source. Invalid number cannot return normally; camel cannot preserve separators.

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-build-script-literals

camel concatenates separator-delimited words with ASCII first-letter uppercase; lit Debug-escapes string; fnum parses f64 then Debug-formats.

##### 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/build.rs.groupant/literals.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

camel(s)=concat(upper_ascii(first(w)) ++ tail(w)) over nonempty split(s,{'_',' ','-'}); lit(s)=Debug(s); fnum(s)=Debug(parse_f64(s)) if parse succeeds, otherwise panic.

### invariant

## Invariant and cost

Scope bytes [1144,1595) in the parent source. Invalid number cannot return normally; camel cannot preserve separators.

### 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: coregate::parse → generated CoreId/CORE included by core.rs. A syntactically complete TSV may still fail literal emission/compiler numeric or identifier constraints.

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

Invalid number cannot return normally; camel cannot preserve separators.

### reverse_reconstruction

RedFox admits red_fox and red-fox; 1.25 admits alternative parsed numeric spellings.

### unicode_case

Non-ASCII initial chars are unchanged by ASCII uppercase.

### escape_transport

Quotes/newlines are escaped into Rust literal text.

### numeric_domain

NaN/infinity parse without rejection; compiler acceptance separate.

### failure_order

fnum parse precedes formatting and reports supplied field context.

### tests

#### Evidence, 2026-10-31

Selected command: rustc --edition=2024 --test onto/build.rs; run generated test binary (debug and -O)

Named outcomes:

- wave29::generated_literal_helpers
- 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: "uppercase -> lowercase" → "wave29::generated_literal_helpers" (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.
