# prag-frames-entities

The groupant beside prag/src/frames.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:** [`prag/src/frames.rs`](https://github.com/ElamurAI/mova-free/blob/main/prag/src/frames.rs)
- **source SHA-256:** `b5047edab2caec4e…`
- **covers:** Entity construction and lexical roles (bytes 56039–83421)
- **part of:** [prag-frames](https://md.groupants.elamur.ai/free/en/mova/prag/src/frames.rs.groupant/)
- **repository folder:** [`prag/src/frames.rs.groupant/entities.groupant`](https://github.com/ElamurAI/mova-free/tree/main/prag/src/frames.rs.groupant/entities.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 source model | [forward](#forward) |
| **ast** | partial | `../syntax.json` |
| **composition** | partial source model | [composition](#composition) |
| **cost** | partial source model | [cost](#cost) |

| **invariant** | partial source model | [invariant](#invariant) |
| **tests** | bounded native and inspected | `../model.md#evidence` |

## 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 |
|---|---|---|---|
| `prag-frames-entities-behavior-complement` | behavior_complement | partial source model | [behavior-complement](#behavior-complement) |
| `prag-frames-entities-reverse-reconstruction` | reverse_reconstruction | partial source model | [reverse-reconstruction](#reverse-reconstruction) |
| `prag-frames-entities-role-head` | field_projection | partial source model | [role-head](#role-head) |

## Model text


Subject: prag/src/frames.rs SHA-256 bfbc2f7905d878080a7e7dd30ae7f1bfe8f07313c3a4cf8f0254be29e72a4b88. Partial source model, finite native evidence. Fixed configuration and admitted finite resource domains; source-derived inner exclusions and ambiguous preimages, no inverse solver.

### forward

Reader builds entities from dependency noun heads, handles pronouns against context/forced ids, gathers modifiers and conjunctions, and projects argument fillers into lexicon roles. Scoped observation: supplied simple noun subject dog yields agent id dog.

### behavior-complement

Universe: supported simple noun subject trees and candidate roles under default fixed configuration. Exclude changing the subject head lemma when no pronoun/alias transformation applies, or adding a patient absent every supported argument route. Outside this small branch absence is unknown.

### reverse-reconstruction

Agent id dog admits arbitrary determiners/modifiers and surface spellings preserving the lemma. A supplied resolved pronoun and an explicit noun can share id while their pron field differs; retain both when only id is observed.

### invariant

Entities retain mention-level details; identity ignores poss/mods/appos. Recursive dependencies require acyclic bounded-depth trees.

### cost

Repeated subtree scans/copying can be quadratic in words and output; lexicon matching adds resource-dependent work. No performance measurement.

### role-head

For the tested simple Nsubj noun -> root verb tree, agent.id equals subject lemma; ctx anchor role token equals subject position. Predicate position is a different coordinate.

### composition

Entity recursion, nominal events and VerbNet alternatives are large unexecuted branches. This fragment is deliberately an observation model, not full lexical semantics.

### epoch-memory

Wave15, 2026-10-30. Prospective repair: reject unresolved right heads in identity with a constant six-item guard, preserving coordination membership and its nontransitivity. Old production failed unresolved_identity_is_symmetric_even_in_coordination; repaired code passes. Compiled guard-removal control fails the same named assertion and exact bytes are restored. Eight focused tests pass twice debug and twice release. No speed, full semantic coverage or universal proof claim.

### limitations

Partial syntax is not expanded semantic AST. No live parser, teacher, whole corpus, GPU or environment mutation. Acyclic input trees and fixed configuration/resource premises matter; malformed recursive ancestry, counter overflow, complete TAM/lexicon/quotation/repair semantics and all active-rule effects remain open. No executable approximant/error budget is claimed.
