# onto-wdvmm-answer-projection

The groupant beside onto/src/wdvmm.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:** [`onto/src/wdvmm.rs`](https://github.com/ElamurAI/mova-free/blob/main/onto/src/wdvmm.rs)
- **source SHA-256:** `184942c7a2af0288…`
- **covers:** v=vec(None,n). For each trimmed-tab row with>=2 fields, i=parse(strip_all_leading#(f0)); if1<=i<=n and lowercase(f1)∈{yes,no,refine}, v[i-1]=(verdict,f2_or_empty). (bytes 3682–4357)
- **part of:** [onto-wdvmm](https://md.groupants.elamur.ai/free/en/mova/onto/src/wdvmm.rs.groupant/)
- **repository folder:** [`onto/src/wdvmm.rs.groupant/answer-projection.groupant`](https://github.com/ElamurAI/mova-free/tree/main/onto/src/wdvmm.rs.groupant/answer-projection.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


### descriptant

#### onto-wdvmm-answer-projection

v=vec(None,n). For each trimmed-tab row with>=2 fields, i=parse(strip_all_leading#(f0)); if1<=i<=n and lowercase(f1)∈{yes,no,refine}, v[i-1]=(verdict,f2_or_empty).

Epoch 2026-10-31: source byte range [3682,4357) with source and range hashes, sharing parent lexical AST. Partial source-derived scope, no semantic proof.

### approximant

#### Scoped forward relation

v=vec(None,n). For each trimmed-tab row with>=2 fields, i=parse(strip_all_leading#(f0)); if1<=i<=n and lowercase(f1)∈{yes,no,refine}, v[i-1]=(verdict,f2_or_empty).

Scope bytes [3682,4357) only. Preconditions and exceptions in this scope's catalog; no claims for parent orchestration.

Executable approximant gap: no useful percentage metric established for these categorical/effectful observations. No surrogate or production substitution. Future caps 1/2/5/10% require a metric/domain and evidence; no numerical error bound follows here.

### invariant

## Scoped observations

n=0 excludes populated slots. Invalid verdict/ID excludes overwrite. Later valid duplicate excludes retaining earlier differing answer.

### Cost

O(answer bytes+n) time and vector allocation; usize n may exhaust memory; no effect beyond allocation.

### composition

#### Scope contribution

v=vec(None,n). For each trimmed-tab row with>=2 fields, i=parse(strip_all_leading#(f0)); if1<=i<=n and lowercase(f1)∈{yes,no,refine}, v[i-1]=(verdict,f2_or_empty).

This fragment contributes only `answer-projection`. Parent owns input acquisition, surrounding dispatch and downstream joins. Complement and compatible antecedents are scoped in models.md rather than copied parent statements.

### models

### behavior_complement

n=0 excludes populated slots. Invalid verdict/ID excludes overwrite. Later valid duplicate excludes retaining earlier differing answer.

### reverse_reconstruction

For each Some(v,why), final accepted occurrence must normalize to v and trimmed third field why; arbitrary earlier/rejected rows. None means no accepted occurrence.

### id_coordinate

External1→internal0, repeated# accepted.

### verdict_quotient

YES/yes/Yes collapse; unknown ignored.

### reason_loss

Third field only; missing empty, fourth discarded.

### pure_cost

O(bytes+n), no filesystem/teacher effect.

### tests

#### Evidence boundary

Parser overwrite, malformed spent records and early over-cap before cwd creation plus parse_answer executed. No teacher/model/environment-success/log effect run.

Parent tests.md names actual selected tests; this scope does not claim all its branches executed. The compiled control listed in parent receipt applies only to the named mutated boundary.
