Elamur Groupantsworld-meanings-records
The groupant beside world/src/meanings.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
Scope: partial source-bound relations over the observations named below. Sufficient memory and terminating dependencies assumed. This is not a universal proof or an executable percentage-error approximant.
forward
Ignore lines starting '#'; split tabs, accept >=6 fields, lowercase first field, store empty date plus fields1..5. BTreeMap keeps last duplicate. Empty keys/fields not rejected when six fields exist.
invariant
Sorted lowercase keys and six fields; no date acquisition. Projection is not full schema validation.
cost
O(B+r log D) comparison-weighted parsing/map insertion; accepted strings stored.
composition
improved supplies embedded bytes to improved_from. improved_dates returns empty map: parser performs no external date read.
behavior-complement
Type: behavior_complement. Subject: world-meanings-records, 2026-10-30. Observation: one completed transition in the stated domain; effects included only where named. Status: partial source model. TSV/output universe: fewer than six fields cannot create row; fields after index5 cannot change stored record. Source-derived inner absence, finite fixtures.
reverse-reconstruction
Type: reverse_reconstruction. Subject: world-meanings-records, 2026-10-30. Observation: one completed transition in the stated domain; effects included only where named. Status: partial source model. Comments, malformed rows, extra columns and overridden earlier rows form compatible antecedents. No unique raw file or edit chronology recoverable.
last-write
Type: state_transition. Subject: world-meanings-records, 2026-10-30. Observation: one completed transition in the stated domain; effects included only where named. Status: partial source model. Accepted rows sharing lowercase k reduce by replacement. Word then WORD retains second record; tests compare all six fields and extra-column equality.
checks
Native synthetic tests: cargo test -p world --lib meanings::wave9_models -- --test-threads=1. Test bodies define finite domains and fixtures. File-level evidence.md records repeated debug/release checks and a compiled negative control. No parser acquisition, teacher request, dictionary write or external assessment executed. Orchestration boundaries are source inspection only.
epoch-memory
2026-10-30: first scoped model. Retain ambiguous fibers, source-order rules and distinction between lexical evidence and truth. Tests observe actual helpers; they do not substitute surrogates into production. Macro token bodies in partial syntax remain opaque. Future updates must rebind exact source bytes and retain these limits. No performance or task-quality improvement inferred.
