Runtime logic unchanged; three sources gain tests. Synthetic witnesses do not validate legal conclusions. Composition: Resolve first sentence position then shifted order gold; count judged, force-act, known authority and joint success; format rounded percentages. 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 Shifted gold lookup and three separate denominators. Resolve first sentence position then shifted order gold; count judged, force-act, known authority and joint success; format rounded percentages. 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: Shifted gold lookup and three separate denominators. Subject: yom-hadin/src/measure.rs, SHA-256 c08d407318b3b1f8c70263d6ce08fd1325f4bbe5bb08c8bab82530a5c57511c7. 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 order position cannot count as judged; '?' gold cannot increase known authority count. 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 Formatted output constrains totals and rounded ratios but many rule/gold mappings remain compatible; no unique match reconstruction. 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. ### empty_order position returns None before modulo, so an empty order yields all unjudged without modulo-zero. 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. ### shift_wrap For len>0 and no addition overflow, shift multiples of len preserve lookup; distinct shift can remove force-act matches. 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. ### joint_unknown both increments for correct force-act and either matching authority or unknown; authority success alone cannot increment both. 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. ### rounding_fiber Formatting zero decimals identifies intervals of percentages; integer numerator/denominator text remains exact while percent alone is lossy. 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: Shifted gold lookup and three separate denominators.. Unmapped models remain source-derived/prospective, not verified by the whole test count. Parent source witness map: [source-evidence.md](https://md.groupants.elamur.ai/free/en/mova/yom-hadin/src/measure.rs.groupant/#source-evidence). Only the described fragment observation is supported; parent test names do not imply every fragment branch executed. ### invariant-and-cost ## Invariant and cost ### Invariant Absent lookup does not increment judged; unknown authority excluded from au_n and ignored for joint success. ### Cost O(sample*order length+matched verb work), shift addition must fit usize. Symbolic bounds, not timings. Resource exhaustion is not tested.
