Runtime logic unchanged; three sources gain tests. Synthetic witnesses do not validate legal conclusions. Composition: Start offset basis, xor each byte then wrapping multiply; protocol reads current rules bytes or empty on error, renders metadata/report and recomputed lattice summaries. 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 FNV byte recurrence and protocol observation boundary. Start offset basis, xor each byte then wrapping multiply; protocol reads current rules bytes or empty on error, renders metadata/report and recomputed lattice summaries. 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: FNV byte recurrence and protocol observation boundary. Subject: yom-hadin/src/report.rs, SHA-256 eb60c61212e8f64ad0b3c67ed5dfbd9623e384479ec54567ed762cc8504b58ff. 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 Protocol itself cannot write files; failed rules read cannot produce a distinct read-error record because default bytes replace it. 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 Fingerprint preimage includes all byte strings hashing to64-bit value; missing and empty files coincide. Full protocol still omits full rules serialization. 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. ### wrapping_recurrence h_{i+1}=(h_i xor byte_i)*0x100000001b3 mod2^64; debug/release agree because multiplication explicitly wraps. 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. ### disk_memory_split Hash comes from j.dir/rules.tsv while count metadata comes from j.rules; they may disagree without error. 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. ### recomputation_join protocol calls judge_all again per defendant, requiring same case/options/jurisdiction semantics as supplied rep for coherent record; arbitrary caller rep may disagree. 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. ### snapshot_assumption Each file read occurs sequentially; concurrent changes can mix revisions, no atomic multi-file snapshot guarantee. 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: FNV byte recurrence and protocol observation boundary.. 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/report.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 No timestamp or machine path in formatted protocol; stability requires same external file bytes and inputs. ### Cost O(file bytes+rendered bytes+judge_all work), whole file buffers. Symbolic bounds, not timings. Resource exhaustion is not tested.
