Elamur Groupantsworld-tests03-rules
The groupant beside world/src/tests03.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 | approximant |
| ast | partial | ../syntax.json |
| composition | partial | composition |
| cost | partial | Cost |
| descriptant | present | descriptant |
| invariant | partial | model.md |
| tests | bounded checks partial scope | tests |
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.
| id | type | label | where |
|---|---|---|---|
behavior_complement | behavior_complement | partial source derived model | behavior_complement |
reverse_reconstruction | reverse_reconstruction | partial source derived model | reverse_reconstruction |
condition_subset | condition_subset | partial source derived model | condition_subset |
label_identity | label_identity | partial source derived model | label_identity |
add_witness | add_witness | partial source derived model | add_witness |

Model text
descriptant
world-tests03-rules
Parse tabbed rules, test base covers extra condition but not removed condition/other label, apply Add/Remove/Replace to singleton base.
Modeling epoch — 2026-10-31
Read full assigned source before editing; prospective predictions retained in external wave29 receipts. This child binds only its stated half-open UTF-8 byte range; other APIs remain parent scope. Evidence is limited to named bounded fixtures; registration is partial modeling. Production behavior unchanged; only inline synthetic tests added to four assigned sources.
approximant
Forward relation
Parse tabbed rules, test base covers extra condition but not removed condition/other label, apply Add/Remove/Replace to singleton base.
Domain and resource limits
Finite valid structures and allocation-success executions under the branch conditions in models.md; integer overflow is outside measured fixtures. Exact categorical relations have no supplied percent surrogate. Macro expansion, arbitrary model quality and external effects are not inferred from syntax.
invariant
Invariant
Parser's first produced rule is required; changes operate on supplied base and do not write a pool.
Cost
Tiny vectors/condition scans; no training or storage.
composition
Composition
This scope contributes rules to its parent. Its forward, complement and preimage are restricted to the bound byte interval. The parent syntax projection is referenced once through ../syntax.json; no independent semantic AST is claimed.
models
behavior_complement
Exclude covers when target relation changes or condition set widens in the checked examples.
reverse_reconstruction
Covered output can originate from any compatible same-label weaker condition conjunction; a two-rule Add result does not identify unique original list without knowing added rule.
condition_subset
Adding14:0 narrows base0:15,4:1.
label_identity
conj→acl is not covered.
add_witness
Add yields length2 and holds_in true.
remove_replace
Remove yields empty; Replace yields exact desired rule at index0.
tests
Bounded checks
Named checks associated with this source (not every fragment branch):
- tests03::stepgame_lexical_reader_reads_new_phrasings
- tests03::stepgame_phrasing_and_corrected_format
- tests03::narrower_variants_and_scoped_changes
17 unique named tests in total passed twice debug and twice release; sorted named outcomes equal across all four runs. Four compiled controls cover bAbI identity, StepGame tie ordering, parser-command state removal and bench-command CPU selection; each exits101 at a runtime assertion, exact source restored then positive exit0. Other sources have finite adversarial fixtures but no separately compiled mutant.
CLI integration coverage is command construction and temporary cleanup only; legacy school/model/cadence paths are not executed. No speed benchmark, GPU, live teacher, datasets or held-out replay.
Limits:
- Only three selected tests; no remaining grammar/social/calendar runtime coverage
- Executable percent approximant unsupported for exact assertions
