Elamur Groupantsworld-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
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 source model | forward |
| ast | partial | ../syntax.json |
| composition | partial source model | composition |
| cost | partial source model | cost |
| descriptant | partial source model | epoch-memory |
| invariant | partial source model | invariant |
| tests | partial source model | checks |
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.
