Elamur Groupantscourt-extract-postprocess
The groupant beside yom-hadin/src/extract.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 |
| cost | partial | model.md |
| descriptant | present | descriptant |
| invariant | partial | Invariant |
| tests | finite native checks | 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.

Model text
descriptant
Adjacent exceptions and address/verb dispute grouping.
Epoch 2026-10-31
Prospective review preceded test edits. Runtime logic unchanged; three sources gain tests. Synthetic witnesses do not validate legal conclusions.
Composition: Attach first alternatives of next conditional rule to previous same-source different-sent rule, then group disputes by first3 address fields+act.
Retained limits: partial syntax, opaque macros; no live corpus, teacher, parser model, production filesystem or frozen gold. Complete semantics and executable approximants remain open.
approximant
Forward model
Adjacent exceptions and address/verb dispute grouping.
Attach first alternatives of next conditional rule to previous same-source different-sent rule, then group disputes by first3 address fields+act.
Not an executable substitute. Percentage approximation is unsupported without a useful metric; future profiles limited to 1/2/5/10% require actual-reference comparison.
models
Typed models: Adjacent exceptions and address/verb dispute grouping.
Subject: yom-hadin/src/extract.rs, SHA-256 4df25340c2de0143478dac2f2b0777d937157f8f6f05706d0d84d301dbf49db2. Domain: bounded finite synthetic rules/cases; valid indices and successful allocation unless a section narrows this. Each relation observes implementation, not legal authority. Status: partial source-derived model, finite evidence mapped in tests.md.
behavior_complement
No exception attachment crosses source or same sent; no dispute newly marked for fewer than4 address components.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
reverse_reconstruction
Given post-state, pre-state includes any prior dispute values overwritten and any exception vector whose suffix was appended; without pre-length uniqueness is lost.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
alternative_loss
Each next condition group contributes first only, so open|close reconstructs open alone in previous exception.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
adjacency_scope
Intervening rule blocks linkage even same source later; no search backward to nearest earlier sentence.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
dispute_cardinality
Distinct authorities>=2 and distinct force/penalty>=2 are independent group predicates, not full pairwise disagreement.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
existing_label_retention
Unqualified groups keep old dispute labels; calling mark_disputes is not a clearing/recompute operation.
Operator: stated relation on this source projection. Assumptions: named domain and unchanged dependencies. Evidence: tests.md maps finite observations; other branches remain source review only.
tests
Checks and evidence
External run label: octopus-wave31-court-2026-10-31; exact commands in native-commands.json, per-source observations in source-test-map.json, numeric exits and named outcomes in raw logs.
19 exact selected native tests twice debug and twice release execute actual linked code on bounded hand-built cases. CLI covers argument helpers only. Full extraction/model initialization, actual jurisdiction loading, protocol disk errors, resource exhaustion and malformed public lattices are unexecuted. Module declarations have compile evidence only.
Three compiled source-behavior mutants: count weight, precedence tie, modal tie; each requires compile success, named assertion failure, exact byte/hash restoration and positive rerun. Legacy fixture interventions count separately. Final observations: external evidence-summary.md.
This node observes: Adjacent exceptions and address/verb dispute grouping.. Unmapped models remain source-derived/prospective, not verified by the whole test count.
Parent source witness map: source-evidence.md. Only the described fragment observation is supported; parent test names do not imply every fragment branch executed.
invariant-and-cost
Invariant and cost
Invariant
Mutations limited to excs of previous and dispute labels of qualifying groups; input order retained.
Cost
O(R+copied clauses+R log R) plus group authority/outcome set costs.
Symbolic bounds, not timings. Resource exhaustion is not tested.
