# translation-flow-many-agreement

The groupant beside tools/translate/src/many.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.

> **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.

## Model text


### descriptant

#### translation-flow-many-agreement

bag skips Rel::Punct, counts concept and(head concept,relation,concept) tuples, normalizes invalid/root heads to ROOT; shared sums min counts. agree ratios2shared/max(total_a+total_b,1). pairing half-rotates source keys only.

##### Epoch 2026-10-31

Prospective predictions saved before edits in the external wave32 tr_flow receipts. Original production bytes preserved; only appended synthetic test modules added. Selected actual helpers exercised; five compiled behavior controls rejected with exact byte restoration and positive reruns. Source syntax projection is partial, not expanded semantic Rust. Diagnostic reconstruction with residual is not semantic understanding or persistent learning.

Valid relation enum, counts fit u32/u64, identical concept labels; punctuation omitted. Empty ratio0.

### approximant

#### Forward relation

bag skips Rel::Punct, counts concept and(head concept,relation,concept) tuples, normalizes invalid/root heads to ROOT; shared sums min counts. agree ratios2shared/max(total_a+total_b,1). pairing half-rotates source keys only.

Scope: source-derived conditional transition model at the manifest SHA. Valid relation enum, counts fit u32/u64, identical concept labels; punctuation omitted. Empty ratio0.

### composition

#### Composition

Scoped children are projections of this file, not independent executables. Main population filtering feeds aggregation; order/text helpers feed measure's exact decoder; many's agreement and storage read the same MTok with intentionally different punctuation treatment, streaming accounting consumes reader costs, clustering consumes normalized PairM. Uncovered branches remain source-derived; finite helper checks do not establish orchestration wiring.

### catalog

## Typed models

All entries bind the source SHA and optional byte range in manifest.json. Observation is one admitted helper call or the explicitly described orchestration trace. Relations are partial source-derived models, not universal proofs. Finite test names and unexecuted effects are in tests.md.

### behavior_complement

Punctuation cannot increase agreement denominator; empty pairing emits no item and no modulo evaluation.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.

### reverse_reconstruction

Ratios lose counts and ordering; bag preimage includes arbitrary punct tokens with adjusted valid heads. Fixed keys and shuffle flag determine pairing inverse rotation.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.

### head_fallback

head0 and head>len both produce ROOT; these source states indistinguishable in edge bags.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.

### multiplicity

Repeated concept contributes its count and shared uses minimum; set-only surrogate overestimates duplicate matches.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.

### empty_ratio

Both empty yields0 not1, a deliberate diagnostic convention rather than reflexive similarity.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.

### half_rotation

n=0 empty, n=1 identity, n>1 cyclic offset floor(n/2) preserves target order and key multiset.

Domain and held-fixed assumptions: the invariant/forward documents for this exact scope. Status: partial source-derived relation; complement is a conditional inner exclusion, reverse retains ambiguity, other types specify the named projection/intervention. Oracle: relevant named synthetic tests when listed; otherwise source inspection only.


### tests

#### Evidence and gaps

##### Native checks

- `many::tests::clustering_puts_near_ones_together`
- `many::tests::agreement_and_its_control`
- `many::tests::a_block_meta_world_is_stored_once`
- `many::tests::versification_drops_a_shifted_chapter`
- `many::wave32::empty_ties_and_accounting`

These selected names ran twice debug and twice release with exact filtering and one test thread; raw logs and numeric status files are in the external octopus-wave32-tr_flow-2026-10-31 receipt directory. All test bodies inspected before selection. Inline cases use only synthetic in-memory records; the existing blocks filesystem test was not selected. Tests listed at file level do not execute every function or this entire scoped fragment.

##### Controls

Five compiled source-behavior mutants: main gate counter suppressed; many strict chapter comparison relaxed; measure noncanonical-gap recording disabled; pages Meta filter reversed; blocks literal-change predicate reversed. All failed the corresponding assertion and passed after original bytes/hash restoration. Zero assertion-only mutants; zero surviving exploratory mutants.

##### Limitations

CLI argument/effect paths, live corpus/model/annotation/training, full Run::verse, page filesystem and reports remain source-derived only. Source syntax projections generated twice and byte-compared. No corpus-quality, persistent-learning, throughput or universal semantic coverage claim.

### invariant-and-cost

#### Domain, invariant and cost

##### Invariant

Valid relation enum, counts fit u32/u64, identical concept labels; punctuation omitted. Empty ratio0.

##### Cost

O(tokens log distinct) maps and O(distinct_a log distinct_b) overlap; pairing O(keys).

Integer additions/casts require representability; finite floating inputs where comparisons are modeled. These symbolic costs are not measurements of corpus throughput. No useful cheaper executable percentage surrogate established; future supported caps only 1/2/5/10%.
