translation-meta-logic
The groupant beside tools/translate/src/logic.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.

Description and epoch memory
Project frames to lowercased events and numbers; lexicon maps verbs/entities. Multiset counts shared events/facts, LCS aligns ordered events. Count negation, both-present modal mismatch, numbers deficit, crossing transitive nonpronoun role or named-role mismatch.
Prospective epoch 2026-10-31
Models predicted metadata loss, bounded coordinate transport and deterministic tie selection before test changes. Production bytes are preserved; only five inline synthetic tests were appended across the group.
Observation epoch 2026-10-31
Selected named native tests are bound in tests.md; raw receipts are external under $MOVA_DATA/runs/octopus-wave32-tr_meta-2026-10-31. Syntax is generated twice and byte-compared. This is partial syntax without macro expansion or semantic resolution.
Gaps
No real annotator/model loads, corpus translation, teacher calls, GPU, full training/evaluation, or language-accuracy claim. No executable percentage surrogate is supplied: an appropriate reference metric/domain is not established. Supported future caps are1/2/5/10 percent only. Residual reconstruction is conditional on retained diagnostics and is not persistent learning.
Independent review correction โ 2026-10-31
The initial complement incorrectly claimed that reordering a fully matched event multiset cannot raise distance. Independent review supplied an actual-source compiled witness: with identity Lexicon, [say(false), say(true)] compared with its reversal has ev=(2,2,2), gaps=0, contra=2 and distance2, while self-comparison has distance0. The verb-only LCS pairs repeated verbs positionally and therefore changes which negations are compared. The corrected model preserves only the verb-multiset gap term under permutation; contradiction distance depends on selected LCS pairs.
Evidence: $MOVA_DATA/runs/octopus-wave32-rt_core-2026-10-31/cross-review-tr_meta.md and tr-meta-review-witness.log; build and witness statuses are0. The witness uses an external exact source copy plus one appended synthetic test. It is independent evidence, not an additional test in this worker's18-name native slice. Production/source hashes and final native receipts remain unchanged.
approximant
Forward relation
Project frames to lowercased events and numbers; lexicon maps verbs/entities. Multiset counts shared events/facts, LCS aligns ordered events. Count negation, both-present modal mismatch, numbers deficit, crossing transitive nonpronoun role or named-role mismatch.
invariant
Invariant and cost
Domain and preservation
Valid role slots0..3, finite tokens, u64/i64 counters no overflow, LCS safe width. perturb numeric increment excludes u64::MAX. These are parser-derived diagnostics, not proof of textual entailment.
Cost
O(nm) LCS cells, O(F log F) fact maps with string comparisons; matched role scans O(sum Rx*Ry). probe runs up to4 comparisons plus membership scans.
Counters and allocation arithmetic must remain representable. String/map costs include compared bytes; finite evidence is not a throughput estimate.
composition
Local composition
The child isolates the translation-meta-logic-logical_words relation inside this source. Its observation is a projection of the complete file relation described in approximant.md; costs overlap and must not be added twice. The remaining code supplies context/table inputs and consumes outputs. External joins: meta MTok feeds profile, Hebrew encoder, fwt and rules; meta LCS feeds logic and alignment-based training; Strong labels optionally override IBM ownership. No runtime chain between all children is asserted.
models
Typed models
Subject: exact source hash in manifest; observation is one call or the stated finite training pass. All models are partial source-derived relations, not universal proof. Domain and resource assumptions are in invariant.md. The baseline exclusion is an inner source-derived claim on that domain; reverse is a compatible-antecedent relation. Specialized relations hold fixed the parameters and tables unless stated otherwise. Evidence uses the named checks in tests.md; individual assertions cover only finite parts, other branches remain prospective.
behavior_complement
Unmatched events are gaps, not contradictions. Missing modal alone cannot contradict. Permuting complete events preserves the verb-multiset gap term. Contradictions depend on the ordered verb LCS and its tie-selected pairs: repeated verbs with different negation or roles can pair differently and increase or decrease distance. No permutation-invariance law is asserted for contradiction distance.
reverse_reconstruction
Logic totals admit many event sequences and fact assignments. Zero contradiction permits omitted events, missing modals and pronoun/name uncertainty; original sentences cannot be reconstructed.
distance_domain
distance=contra+(ev_left+ev_right-2*shared)/2, nonnegative under valid aggregate relation.
crossing_precedence
Both transitive and a nonpronoun crossed identity yields one contradiction then skips named-role comparison.
numeric_multiset
Number contradiction=max(lengths)-multiset_intersection; number normalization aliases sixty/threescore.
sensitivity_scope
perturb only matched event positions; absence of applicable perturbation is no evidence of sensitivity.
tests
Checks and evidence
- logic::tests::every_kind_of_change_is_seen
- logic::tests::contradictions_and_their_control
Exact cargo commands use package translate, binary translate, --offline --locked and -- --exact --test-threads=1. External native-commands.json lists every name; debug and release run twice, numerical status and named outcomes retained. Some tests target other portions of the file; this fragment has source reasoning plus only the overlapping assertions.
Compiled controls mutate production decision expressions and restore exact original bytes; see external mutations.json and restoration receipt. No assertion-only mutation is counted. The evidence summary is authoritative for completed receipts. Scoped source reasoning and finite tests do not establish total branch coverage.
Recorded 2026-10-31 result
This source contributes 2 exact named checks to the 18-check group. Every name passes twice in debug and twice in release, with identical sorted outcomes. A compiled production mutation in logic.rs was rejected by its selected runtime assertion; its original and restored SHA-256 match. All 18 checks pass again after all nine restorations. There were nine rejected production mutations, zero assertion-only mutations and zero surviving controls in this batch. Nine source projections matched byte-for-byte across two generations. No original production bytes changed.
The augmented-registry check has no owned source or fragment diagnostic. Only root-owned inference-core/mova child/source bindings await integration. A first isolated-registry experiment was unsuitable because the checker inspects unrelated existing sidecars; those failures are retained separately and are not counted as semantic controls.
