# global-build-auxiliary
The groupant beside global/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:** [`global/build.rs`](https://github.com/ElamurAI/mova-free/blob/main/global/build.rs)
- **source SHA-256:** `f51324dd9ccd11f9…`
- **covers:** Auxiliary score/idiom tables and expression copy. (bytes 15184–21195)
- **part of:** [global-build](https://md.groupants.elamur.ai/free/en/mova/global/build.rs.groupant/)
- **repository folder:** [`global/build.rs.groupant/auxiliary.groupant`](https://github.com/ElamurAI/mova-free/tree/main/global/build.rs.groupant/auxiliary.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.

## 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
#### global-build-auxiliary
Auxiliary score/idiom tables and expression copy.
##### 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
Read optional real cells into sorted map, derive lexical verb/noun IDs, emit. Read tale rows in input order with existing-pair/score/duplicate gates. Read closed idioms into sorted pair map validating kind; copy expressions bytes as UTF-8 text or empty.
##### 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
Real cells unique with scores0..4; tale keys subset of real. Tale order is not sorted by code. Expressions copy is separate write.
##### Cost and resources
O(B+R log R) plus output bytes; entire optional files read.
### cost
#### Cost and resources
O(B+R log R) plus output bytes; entire optional files read.
### composition
#### Composition
Auxiliary score/idiom tables and expression copy.
Read optional real cells into sorted map, derive lexical verb/noun IDs, emit. Read tale rows in input order with existing-pair/score/duplicate gates. Read closed idioms into sorted pair map validating kind; copy expressions bytes as UTF-8 text or empty.
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
Bad score/duplicate/unknown tale key and bad idiom kind panic; missing/unreadable optional files do not.
### reverse_reconstruction
IDIOMS drops count/source; absence and unreadable file collapse to empty. Tale sequence retains order, while real table sorts away it.
### score_domain
u8 parse failure defaults9, then >4 rejects; negative text rejects.
### tale_order
Reversed valid tale keys emit reversed rows; downstream binary search assumptions are not proven.
### closed_boundary
closed_data reads `$MOVA_PETA_DATA/global/`, the directory taken from the environment, else from the line `MOVA_PETA_DATA=` of the manifest-relative `peta/paths.env`; with neither it names an absent file under OUT_DIR, so the tables read as empty (public checkout). 2026-11-04: the tables left the repository (Peta holds no data); the old sibling `peta/global/data` is no longer read.
### partial_effect
expressions may be written before later final global.rs write failure; no rollback.
### tests
#### Evidence
Parent source checks (a fragment inherits only the behavior they actually exercise):
- wave29::block_and_code_boundaries
- wave29::isolated_seed_compile_and_duplicate_gate
- wave29::build_child
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.
