# study-proposal

The groupant beside tools/enrich/src/study.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:** [`tools/enrich/src/study.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/enrich/src/study.rs)
- **source SHA-256:** `8bdc286a3d410509…`
- **covers:** Literal proposal generation (bytes 5218–7933)
- **part of:** [study-orchestrator](https://md.groupants.elamur.ai/free/en/mova/tools/enrich/src/study.rs.groupant/)
- **repository folder:** [`tools/enrich/src/study.rs.groupant/proposal.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/enrich/src/study.rs.groupant/proposal.groupant)
- **repository commit:** `48f2e6f74146`

> **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 | [forward](#forward) |
| **ast** | not materialized |  |
| **composition** | partial | [composition](#composition) |
| **descriptant** | present | [epoch-memory](#epoch-memory) |
| **invariant** | partial | [invariant](#invariant) |
| **tests** | partial bounded checks | [checks](#checks) |

## 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 |
|---|---|---|---|
| `study-proposal-forward` | forward_relation | partial source model | [forward](#forward) |
| `study-proposal-behavior-complement` | behavior_complement | partial source model | [behavior-complement](#behavior-complement) |
| `study-proposal-reverse-reconstruction` | reverse_reconstruction | partial source model | [reverse-reconstruction](#reverse-reconstruction) |

## Model text


Partial source model, 2026-10-29. The raw Rust file remains authoritative. AST is not materialized; byte ranges are snapshot anchors, not semantic proofs.

### forward

Let L(P,B) be the ordered raw rows from unblocked sentences satisfying ten-column token shape, nsubj/obj noun/proper-noun, verb head, unique literal spelling and alphanumeric boundaries. Forward output is take16(Pool(L(P,B))). This models token clozes, not semantic entailment.

### behavior-complement

In the universe of packet/blocklist/output triples, any output with a blocked source, invented literal answer or more than sixteen items is outside the generator relation. This inner complement does not classify every malformed parse.

### reverse-reconstruction

Given output Q, compatible inputs include exactly packets and blocklists whose ordered accepted raw rows yield Q after pooling/capping. Unemitted rows and blocked sentences remain ambiguous; empty output does not identify an empty packet.

### coupling

Blocking precedes the global pool: Pool(L(P,B)) = Pool(L(P without B,empty)). Removing a source can remove distractors for other sources, so filtering final outputs is not equivalent. The 64-subset oracle checks that coupling.

### composition

The pool child consumes only accepted raw rows in original sentence/token order. Parent adds literal eligibility, source exclusion and the sixteen-result stop. Shared canonicalization is assumed; the child cost already includes its raw scans, so do not count them twice. Parsing plus head searches costs O(sum tokens^2); pooling is O(R^2 log R) plus string work.

### invariant

Forward and reverse observations refer to the same fixed source snapshot and dependency behavior. Ordering is deterministic for fixed inputs; filesystem/environment stability is assumed where relevant. The complement is an inner bound relative to this fragment's input/output universe.

### checks

See the file-level tests.md for executed bounded checks and limits. The first three model relations are specifications; tests sample correspondence rather than proving all inputs. No expanded semantic AST or executable general inverse solver exists.

### epoch-memory

2026-10-29: retained the file-level 23 models and added this finer scope. An initial incidence oracle incorrectly treated three-byte fox as a token; the existing tokenizer rejects it. Corrected the independent membership matrix rather than changing production behavior. This is a model correction, not an algorithm defect.
