# world-idioms-mining-export

The groupant beside world/src/idioms.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_fragment
- **status:** partial source bound model
- **source:** [`world/src/idioms.rs`](https://github.com/ElamurAI/mova-free/blob/main/world/src/idioms.rs)
- **source SHA-256:** `ac32513e83eaf56b…`
- **covers:** Source scope mining-export; see model.md for functions and dependency limits. (bytes 4467–11377)
- **part of:** [world-idioms](https://md.groupants.elamur.ai/free/en/mova/world/src/idioms.rs.groupant/)
- **repository folder:** [`world/src/idioms.rs.groupant/mining-export.groupant`](https://github.com/ElamurAI/mova-free/tree/main/world/src/idioms.rs.groupant/mining-export.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.

## 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.

## Model text


### forward

Merge dictionary evidence, accumulate OBJ marginals, retain last duplicate pair count/books, gate count/books with dictionary bypass but count>=3 always, classify by matrix and PMI. Aggregate two-word events and export sorted rows then final map.

### invariant

OBJ rows require count>=3 even with dictionary evidence. Particle rows require min only. Final map is pair-unique, detailed output need not be. Successful writes do not imply atomic publication.

### cost

For B bytes, U pairs, E event rows and R retained rows: O(B+(U+E)log(U+E)+R log R), plus matrix lookup and output bytes. Sorting is separate from accumulation; no timing claim.

### composition

This fragment shares source and state with its siblings; root composition specifies ordering and latent dependencies. It is not an independent replacement API.

### epoch-memory

Predicted first minimum dictionary rank and first MWE row; finite tests confirm. Limitations: substring flags, unconditional first-line discard, duplicate last pair versus summed marginals, absent phrasal book gate and unused k%1 set. Production unchanged.

### checks

Five native tests: 64 rank triples, eight phrase/POS contexts plus header, 80 MWE flag/type/title combinations, reversed order, four pair-key preimages. Full run/exports not executed. Fragment scopes are defined by source byte ranges; root evidence distinguishes executed helper tests from inspection-only branches.

### behavior-complement

Within the scoped input/output universe, violating dependency-feedback or export-collision is excluded by the source model. This inner constraint family does not claim a complete complement.

### reverse-reconstruction

Converse retains all inputs compatible with the scoped output and fixed dependencies; projections and discarded candidates generally create multiple antecedents. No single inverse is claimed.

### dependency-feedback

Matrix score consults existing global idiom table, clamps known literal OBJ scores, and can consult known layer. Freeze prior snapshot.

### export-collision

Particle rows use min only, no min_books; insertion overwrites same OBJ key in global map although detailed output can contain both. Two-file output is not atomic.
