# rt-mixed-link

The groupant beside tools/roundtrip/src/mixed/link.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

- **kind:** groupant
- **status:** partial source bound model
- **source:** [`tools/roundtrip/src/mixed/link.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/roundtrip/src/mixed/link.rs)
- **source SHA-256:** `9ec656e7db9174a6…`
- **repository folder:** [`tools/roundtrip/src/mixed/link.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/roundtrip/src/mixed/link.rs.groupant)
- **repository commit:** `855da7bd4a7b`

> **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.

## Components

| component | label | where |
|---|---|---|
| **approximant** | partial | [approximant](#approximant) |
| **ast** | partial | `syntax.json` |
| **composition** | partial | [composition](#composition) |
| **cost** | symbolic source derived | [invariant](#invariant) |
| **descriptant** | present | [descriptant](#descriptant) |
| **invariant** | partial | [invariant](#invariant) |
| **tests** | executed bounded checks | [tests](#tests) |

## 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.

| id | type | label | where |
|---|---|---|---|
| `behavior_complement` | behavior_complement | partial source derived model | [behavior_complement](#behavior-complement) |
| `reverse_reconstruction` | reverse_reconstruction | partial source derived model | [reverse_reconstruction](#reverse-reconstruction) |
| `greedy_order` | greedy_order | partial source derived model | [greedy_order](#greedy-order) |

## Model text


### descriptant

#### Descriptant

##### Prospective epoch

2026-10-31 source review predicted: Lex normalizes Hebrew letters and English collapsed whitespace. link processes verse candidates then names, accepting first eligible pair only if Hebrew key and English value unused; None returns empty. rename touches entity IDs and coordinated IDs in roles/obliques; inverse reverses the map. Resource model: Pair enumeration O(H*E) with entity scans and gloss/map logarithmic lookup; normalization/string costs explicit; output memory O(accepted links+examples capped at1000). External prospective.md predates test additions and preserves APIs, effect order, hazards and interaction hypotheses.

##### Observed epoch

Bounded real helper checks in tests.md constrain these models; syntax is a partial lexical projection with no macro expansion, name resolution or proof. Production expressions unchanged; six inline test modules added. Compiled mutants are temporary and exactly restored. Existing malformed-input and nonfinite domains remain explicit, not silently repaired. Parent composes this scope with siblings without adding overlapping costs twice.

Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded.

### approximant

#### Forward relation

Lex normalizes Hebrew letters and English collapsed whitespace. link processes verse candidates then names, accepting first eligible pair only if Hebrew key and English value unused; None returns empty. rename touches entity IDs and coordinated IDs in roles/obliques; inverse reverses the map.

Domain: Stable piece/frame order; valid frames; finite counters without overflow. Arbitrary inverse maps may collide; roundtrip rename additionally requires original renamed IDs not to collide with untouched target-domain IDs.

### invariant

#### Invariant and cost

##### Invariant

Stable piece/frame order; valid frames; finite counters without overflow. Arbitrary inverse maps may collide; roundtrip rename additionally requires original renamed IDs not to collide with untouched target-domain IDs.

##### Cost

Pair enumeration O(H*E) with entity scans and gloss/map logarithmic lookup; normalization/string costs explicit; output memory O(accepted links+examples capped at1000).

##### Limits

Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded. No percentage surrogate is implemented: categorical parsing/effect observations lack an admitted numerical error metric. Any future profile must define its metric/domain and use only1/2/5/10 percent caps.

### composition

#### Local composition

Lex normalizes Hebrew letters and English collapsed whitespace. link processes verse candidates then names, accepting first eligible pair only if Hebrew key and English value unused; None returns empty. rename touches entity IDs and coordinated IDs in roles/obliques; inverse reverses the map.

Children select narrow source functions with their exact byte intervals. Remaining branches stay in the file model; fragments are not exhaustive partitions. Calls and state joins follow the forward relation, not folder order. Shared scans/helpers are counted once in whole-file costs. Complement of composition is not union of complements; reverse composition retains compatible intermediates and caller premises.

### models

## Typed source-bound relations

Subject: exact source SHA-256 in manifest. Domain and resource premises are in invariant.md. Each model is partial, source-derived, over a single helper invocation or the described finite trace. Complements are proposed inner exclusions under those premises; reverse relations retain all compatible antecedents, with no unique inverse claim. The oracle is the named checks in tests.md; unexecuted cases remain hypotheses. No numerical approximation certificate.

### behavior_complement

Excluded: None produces links; accepted link relation duplicates an English value. Names need not share verses and unverified links do not establish correctness.

### reverse_reconstruction

Returned map admits many gloss dictionaries, verses and duplicate candidate histories. Injective map inverse recovers mapped IDs under no-collision premise, not lost dictionary text.

### greedy_order

First matching English entity can already be taken; code does not search a second candidate after rejection.

### gold_partition

right+wrong+unverified equals accepted verse+name links on nonoverflowing execution.

### normalization_fiber

Consonants and collapsed spaces erase distinctions; same normalized keys need not identify unique input text.

### rename_scope

Only entity id and and lists change; verbs, attributes, pronoun fields remain fixed.

### tests

#### Checks and evidence

Named source/helper checks: mixed::link::wave32_tests::greedy_links_and_inverse.

Wave32 on2026-10-31:10 distinct exact tests passed twice debug and twice release, with equal sorted named outcomes. This node claims only its listed subset; empty subset means source review only. Five actual source-behavior mutants compiled, failed assertions, restored exact bytes/hash, and passed focused green reruns. No assertion-only mutants; existing swapped-input controls are separate. Receipt bundle: $MOVA_DATA/runs/octopus-wave32-rt_mixed-2026-10-31 (native-commands.json, source-test-map.json, mutation-results.json, *.status/*.log). No live corpus, teacher, frozen assessment, download or production data used.

Finite synthetic helper evidence only; live corpora, parser/model loading, full orchestration and filesystem failure races excluded.
