# english-orchestration

The groupant beside models/english-orchestration.groupant 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_group
- **status:** partial descriptive instance
- **bound sources:** 8
- **repository folder:** [`models/english-orchestration.groupant`](https://github.com/ElamurAI/mova-free/tree/main/models/english-orchestration.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

## 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

#### english-orchestration: wave27

main imports en modules declared by lib; license gate is only on train dispatcher, not a general evaluation gate. ctxeval consumes ctx::gold and ctx::Rng plus ud::Scores. diag calls parse baseline/kbest/constrained and uses gram enums. emode force/fix connect to annotation/tagger and embedded registry/dictionary; build output binary indices must match dict consumers (not independently validated here). Shape agreement by ID/token count does not prove form identity or valid trees.

This source-bound partial group organizes existing Mova code. Native evidence and excluded effects are recorded in source sidecars and the root wave27 report. Registration is not a universal proof or whole-system runtime claim.

### model

## english-orchestration

### forward

CLI selected command composes argument projection with library calls. train: commercial_gate(paths) then output argument check then delegated train/save/reload; no train call on rejected license. Context evaluation: Setup→gold/derived/shuffled→masked Ctx→tagger/parser features→aligned System runs→seed means and paired bootstrap. build.rs produces little-endian lexicon/layout/constants consumed by dict/morph and thus EModE ending decisions. diag consumes parser outputs and gold geometry, with constrained decode failures falling back to baseline.

### invariant

Module declarations establish one shared namespace but prove no module semantics. Context mask removes layers, coordinates remain zero-based token positions versus one-based heads. License admission reads path names only. Paired bootstrap samples same sentence indices for both systems. No global transactional guarantee: file/stream prefixes survive later failures.

### cost

Add selected adapter/delegated costs; no sum over unselected commands. build indexes expected linear/worst quadratic; ctx stype O(n²), mention handling O(bytes+mentions*stack depth), shuffle has unbounded rejection-loop worst case. ctxeval O(SRT+SRBN+SB log B), diag geometry up to O(n³) plus decoder cost. CLI folds O(k*bytes). No speed measurement or claim.

### composition

main imports en modules declared by lib; license gate is only on train dispatcher, not a general evaluation gate. ctxeval consumes ctx::gold and ctx::Rng plus ud::Scores. diag calls parse baseline/kbest/constrained and uses gram enums. emode force/fix connect to annotation/tagger and embedded registry/dictionary; build output binary indices must match dict consumers (not independently validated here). Shape agreement by ID/token count does not prove form identity or valid trees.

### domain

Bounded synthetic strings, valid aligned token arrays and in-range heads for geometry; valid System shapes with >=1 baseline and seeds, bootstrap B>=1 for comparison. Effects limited in tests to isolated temporary synthetic build/fold/report files. Real training/model/corpus paths are source-derived only.

### limitations

No corpus, teacher, API, GPU, held-out or training run. Existing compiled dictionary/registry tables participate only where safe tests call ordinary functions; dictionary-sensitive early-return tests excluded. u32 narrowing, allocation failure, arbitrary malformed heads and environment OnceLock alternate modes remain gaps.

### checks

- 14 named Rust tests twice debug and twice release, identical sorted outcomes, exits0
- Build entrypoint empty/synthetic/tag-before-id rejection scenarios twice per profile; successful outputs byte-identical
- 7 actual compiled mutations, compile0 / assertion101 / exact restore / rerun0
- 8 paired syntax projections identical; 5 source-scoped main fragments
- Strict Clippy exit101 on existing build.rs:51 manual_is_multiple_of

### catalog

### behavior-complement

Across train dispatch, exclude model training/saving when any path first fails commercial_gate; across folds k<2 exclude input read and directory writes; across test_ctx None exclude path reads. Within aligned reports exclude independent baseline/treatment bootstrap draws. These scoped exclusions do not forbid partial output after later I/O failures.

### reverse-reconstruction

Given accepted gate and rendered report, compatible antecedents are all path lists mapping to admitted sources and aligned gold/system runs producing the rounded means/intervals/group counts. They include arbitrary directory spellings, different per-seed outcomes with equal aggregates, erased annotation features and omitted examples. No unique reconstruction from report/gate result; feature ablations and constant/hash collisions further merge antecedents.

### context-transport

Doc nonempty sentence order→Ctx/docs; train_ctx filters tagged sentences and offsets document IDs; test_ctx validates pass1 IDs/counts; masking occurs after derivation/shuffle. ctxeval System loader checks IDs/counts but not forms. Crossing these adapters requires explicit order alignment, not just equal lengths.

### effect-prefix

Build reads then writes lexicon/layout/words sequentially; folds creates dir then fold/rest files; train saves before reload comparison; conversion streams completed files before later failure. A failure may retain prefixes and no rollback is modeled.

### coordinate-join

Token vector index i maps head ID i+1; zero is root. Context entity features use zero/no-layer, one/outside, >=2 encoded type/status. Build offsets distinguish byte offsets from record counts and symbol IDs; none are interchangeable.

### uncertainty-join

Compile visibility of lib is not execution evidence. Fourteen finite tests and seven mutants falsify selected contracts only; unknown live paths and unsupported percentage approximants remain explicit. Bootstrap intervals are sampling summaries, not proofs of real-task improvement.
