# world-domains-configuration

The groupant beside world/src/domains.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:** [`world/src/domains.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/domains.rs)
- **source SHA-256:** `5ecf532157570f30…`
- **covers:** knobs declares eight shipped values and search grids. default_cfg starts full defaults then overlays recognized name=value environment-file entries. domains_with resolves absent/nonfinite overrides to shipped defaults; finite values remain allowed off-grid, including zero/negative/fractional values with downstream Rust cast semantics. (bytes 1229–5086)

> **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


### forward

knobs declares eight shipped values and search grids. default_cfg starts full defaults then overlays recognized name=value environment-file entries. domains_with resolves absent/nonfinite overrides to shipped defaults; finite values remain allowed off-grid, including zero/negative/fractional values with downstream Rust cast semantics.

### invariant

Missing/nonfinite legal_k cannot become accidental zero. Finite zero is preserved. tune constructs full base and clones/inserts; family state_cfg overlays defaults; its ablations explicitly insert finite zero. No inspected caller removes keys.

### cost

Eight fixed entries: constant-sized configuration maps. Environment-file load is linear in bytes; each domains_with call rebuilds shipped defaults. No speed claim.

### composition

Actual callers: domains supplies default_cfg; score_set classifies supplied Labelled rows; run/load_set/eval annotate and repair first. Native tests execute domains_with -> Matrix::global_in -> judge -> sense::arguments -> original-form reasons. tune/family build full default maps and alter explicit values; absent-map fallback is a deliberate public-API semantic repair.

### epoch-memory

2026-10-30 initial source-bound epoch. Old native witnesses exposed role-index panic and spurious formal activation with empty overrides. Guards/default resolution repair these; explicit finite values and sparse-cell gap semantics remain. No optimization, surrogate or percentage bound is claimed.

### checks

cargo test -p world --lib domains::wave11_models -- --test-threads=1. Root evidence.md records repeated profiles and mutants. Partial syntax leaves macro bodies opaque; no semantic AST, parser, teacher or corpus execution.

### behavior-complement

Universe: terminating scoped calls and their outputs. Inner absent-behavior model excludes outputs contradicting: Missing/nonfinite legal_k cannot become accidental zero. Finite zero is preserved. tune constructs full base and clones/inserts; family state_cfg overlays defaults; its ablations explicitly insert finite zero. No inspected caller removes keys. Unknown external behavior remains outside this exclusion.

### reverse-reconstruction

Normalized settings admit omitted keys, explicit defaults and nonfinite values; ignored keys/comments disappear. A normalized map does not identify its originating file.

### coupling

Override intervention holds annotations fixed: absent/nonfinite settings match shipped values; finite off-grid thresholds remain supported. Search grids are recommendations, not admissibility constraints.

All typed entries bind this scope and manifest source revision. Domain and observation/operator are stated above. Status: partial source-derived relations with finite evidence named in checks, assuming stable dependencies and bounded successful execution. Reverse relations preserve ambiguity, with no complete-search or causal claim.
