# jobs-main-flags

The groupant beside tools/jobs/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/jobs/src/main.rs`](https://github.com/ElamurAI/mova-free/blob/main/tools/jobs/src/main.rs)
- **source SHA-256:** `ddb2e9ecf8ef78a1…`
- **covers:** Find first args element equal key, take following string, parse f64; any missing step yields None. (bytes 2699–2849)
- **part of:** [jobs-main](https://md.groupants.elamur.ai/free/en/mova/tools/jobs/src/main.rs.groupant/)
- **repository folder:** [`tools/jobs/src/main.rs.groupant/flags.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/jobs/src/main.rs.groupant/flags.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.

## 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

#### jobs-main-flags

##### Epoch 2026-10-31

Prospective inspection identified this relation before additions: Find first args element equal key, take following string, parse f64; any missing step yields None.

The production implementation is unchanged; only selected inline tests are appended. Source-bound syntax is generated twice and compared. Native checks exercise bounded helpers; entry orchestration, teacher calls, models and corpora remain source-derived. Partial syntax is not semantic proof. Preserve failure prefixes and ambiguity when refining this model.

### approximant

#### Forward relation

Find first args element equal key, take following string, parse f64; any missing step yields None.

##### Composition

This fragment isolates the stated helper relation; parent composition retains surrounding effects and failures.

### catalog

## Typed observations: jobs-main-flags

Subject: tools/jobs/src/main.rs, SHA-256 ddb2e9ecf8ef78a1d13ce00030932ef2703746e56c52f29c33fc428366f20a29. Domain: bounded source inputs, declared filesystem/environment state and normal allocations. Each view is a partial source-derived relation, not a universal proof. Observation is one helper call or the explicitly described trace. Checks are in tests.md; unexecuted effects remain gaps.

### behavior_complement

A later valid duplicate cannot repair invalid first occurrence. Missing key or value cannot produce Some.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### reverse_reconstruction

Some(v) admits all argv vectors whose first key successor parses v, arbitrary prefixes without key and arbitrary suffix. NaN lexical variants and equivalent floats prevent uniqueness.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### first_index

position scans forward exact equality; no --key=value syntax and no option namespace parsing.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### missing_successor

Key in final slot maps None, same observation as absent key and parse failure.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### numeric_domain

f64 parse admits negatives, infinity and NaN. Returning Some is syntactic parse success, not a valid budget.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### caller_default

Caller unwrap_or substitutes only None, never Some(NaN); default 7200 secs does not sanitize NaN.

Scope: the bound source interval and stated assumptions. Evidence: source inspection plus the checks explicitly named in tests.md; no finite check establishes all inputs.

### tests

#### Checks and limits

wave33_tests::flag_first_occurrence_and_nonfinite covers repeated/invalid/missing/negative/NaN cases.

Exact native outcomes and command metadata are retained in the external wave33 cycle receipt bundle. Selected names run twice in debug and release; syntax is independently regenerated twice. Compiled mutations and source restoration receipts distinguish behavior changes from assertion-only controls. These claims are finalized in evidence.md. No live teacher, real model/corpus, benchmark CLI or lesson-learning CLI is run.

### invariant-and-cost

#### Invariant and cost

No duplicate retry and no finite/positive constraint.

O(argument count+numeric token bytes), constant extra memory.

No executable percentage surrogate is claimed: effects, categorical acceptance and report text have no justified approximate metric here. Future profiles require a useful metric, zero case, reference and evidence at caps 1/2/5/10%.
