court-lattice

The groupant beside yom-hadin/src/court.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.

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.

Case facts to capped rule matches, choice lattice, evaluation and bounded tip search.

Epoch 2026-10-31

Prospective review preceded test edits. Runtime logic unchanged; three sources gain tests. Synthetic witnesses do not validate legal conclusions.

Composition: Match defendant anchors by highest Cover with first tie; build condition/exception points and discard completed duties; rank/cap16/reindex; append disputes, precedence and suspension. Evaluate blocked/local eligibility, dispute winners, principle key and optional suspension. Count weighted firing masks times global assignments; tipping enumerates distinct-point alternative sets.

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

Case facts to capped rule matches, choice lattice, evaluation and bounded tip search.

Match defendant anchors by highest Cover with first tie; build condition/exception points and discard completed duties; rank/cap16/reindex; append disputes, precedence and suspension. Evaluate blocked/local eligibility, dispute winners, principle key and optional suspension. Count weighted firing masks times global assignments; tipping enumerates distinct-point alternative sets.

Not an executable substitute. Percentage approximation is unsupported without a useful metric; future profiles limited to 1/2/5/10% require actual-reference comparison.

Obligation boundary: an act anchor gives duty0 for positive conduct and duty2 for negation. duty0 is skipped before matching/cap, while duty2 remains; a condition anchor derives duty from clause_status. Labels use act_verb (first act, else first condition), not patient text. The independent integration review supplies additional completed/negated-duty witnesses; local checks do not claim these branches directly.

Subject: yom-hadin/src/court.rs, SHA-256 c780d974b015dcefc5018d326ca5f1e0ec47af0c8fbd23927213a8848285b099. 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

In generated valid lattices, excluded traces include blocked rule firing, negated forbidden act conviction from that rule, completed duty retained, and suspension outside2..max. No bounds are claimed for malformed externally assembled Lattice assignments.
