# value-cli-bench_transport

The groupant beside tools/value/src/main.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/value/src/main.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/value/src/main.rs)
- **source SHA-256:** `dd78d961585fd888…`
- **covers:** Append MOVA_ROOT/BENCH_OUT; run fixed HOME-relative bench path, optional --quick; read TSV; choose last time-tab header and final line, zip and drop two columns. (bytes 1689–2522)
- **part of:** [value-cli](https://md.groupants.elamur.ai/free/en/mova/tools/value/src/main.rs.groupant/)
- **repository folder:** [`tools/value/src/main.rs.groupant/bench_transport.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/value/src/main.rs.groupant/bench_transport.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

#### value-cli-bench_transport

Append MOVA_ROOT/BENCH_OUT; run fixed HOME-relative bench path, optional --quick; read TSV; choose last time-tab header and final line, zip and drop two columns.

##### Epoch 2026-10-31

Prospective full-source read preceded edits. Model separates source-derived effects from bounded actual-helper evidence. Bibliography host identity old code admitted foreign authorities; a failing fixture motivated the narrow HTTP(S) exact-authority repair. Other production bytes were retained; added test modules are cfg(test). Topic run now uses the same canonical ID guard for JSONL admission; an old-code failing fixture confirms foreign matched entries remain only in abstract listings. Namespace compilation is representation evidence, not independent runtime coverage. Value workflow and bench transport remain unexecuted. No live data, network, model, DB or benchmark invocation was used.

### approximant

#### Forward model

Append MOVA_ROOT/BENCH_OUT; run fixed HOME-relative bench path, optional --quick; read TSV; choose last time-tab header and final line, zip and drop two columns.

Domain and assumptions: Source-derived only; workflow not run. Header and final row can differ in width and meaning. Empty metric vector can succeed.

This source-derived relation abstracts allocation, formatting and external failures; no executable percentage surrogate is asserted. Categorical decisions/effects have no supported error metric yet. Future budget caps are 1%, 2%, 5%, 10% only.

### catalog

## Typed model catalog

Subject: exact manifest source SHA-256 and optional byte scope. Domain/assumptions: forward and invariant companion. Observation is one completed helper transition or the stated IO prefix; external interference is excluded for finite fixtures. All models are partial source-derived specifications; the complement is an inner set of excluded behaviors, the reverse a compatible-antecedent relation. Evidence: tests.md; unsampled branches are not proven.

### behavior_complement

Missing time-tab header excludes metrics; child failure excludes file read.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### reverse_reconstruction

Observed metric pairs admit arbitrary preceding lines and unpaired trailing columns; no unique run reconstruction.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### header_selection

Last matching header wins, independent of previous schema.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### zip_truncation

Metric count=max(0,min(headerColumns,rowColumns)-2), no width rejection.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### row_selection

Final text.lines() entry used even if it is a header/nondata row.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### override_order

Appended MOVA_ROOT/BENCH_OUT override earlier equal keys in child Command; quick supplies one argument.

Operator and approximation: the stated constraint on the source transition, with all unmentioned state held fixed; not a total solver or uniqueness claim. Falsifiable oracle: compare actual helper outputs/effect order on a bounded input satisfying the domain. Current executed subset and unsupported observations are listed in tests.md.

### tests

#### Checks and limits

Exact target-qualified native names for this source family:

- wave33_tests::subprocess_status_precedes_stdout_and_reverses_stderr_tail

Run each selected exact name twice debug and twice release, one test thread, offline/locked dependencies. External wave33 sources receipts contain numeric statuses/raw logs and sorted outcome comparisons. Scoped children inherit only relevant evidence: parse/IDs directly exercised; admission/check/merge actual helpers exercised; subprocess actual helper exercised. bench_transport has source-derived evidence only, never an executed benchmark. Library namespace is compile/representation evidence.

Compiled source controls change bibliography license threshold, sources size guard and value status guard; targeted assertions must reject, then exact backup restoration and positive rerun. Finite controls are not comprehensive fault coverage. See evidence.md at source root for receipts summary.

### invariant-and-cost

#### Invariants and costs

Source-derived only; workflow not run. Header and final row can differ in width and meaning. Empty metric vector can succeed.

Opaque benchmark runtime then O(TSV bytes) and O(min(column widths)) output.

Bounds are symbolic, conditional on stated domain and successful allocation. No unmeasured speedup or universal finite-test guarantee.
