# jobs-main

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
- **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…`
- **repository folder:** [`tools/jobs/src/main.rs.groupant`](https://github.com/ElamurAI/mova-free/tree/main/tools/jobs/src/main.rs.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

## 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

##### Epoch 2026-10-31

Prospective inspection identified this relation before additions: CLI log reads default-empty log; run splits options at first --, selects name/defaults, spawns command and samples process tree until exit or limit. RSS overflow takes precedence over elapsed time; reverse-tree TERM then 5s wait and KILL ends overrun. Append estimate/actual record then exit child code.

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

CLI log reads default-empty log; run splits options at first --, selects name/defaults, spawns command and samples process tree until exit or limit. RSS overflow takes precedence over elapsed time; reverse-tree TERM then 5s wait and KILL ends overrun. Append estimate/actual record then exit child code.

### Composition

cycle invokes jobs run around drafts with explicit limits, but jobs process accounting is an external effect, not proven by cycle helper tests. Scoped option model feeds monitor limits.

### catalog

## Typed observations: jobs-main

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

Invalid first numeric flag does not fall through to later duplicate. RSS excess selects memory reason even if time also exceeds; already-exited child is handled before next sample.

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

Log record admits many process trees between samples, rounded CPU/wall values and missed peaks; original command argument boundaries are lost in cmd.join(space). Cannot reconstruct exact workload or enforce peak from report.

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.

### option_cast

mem_gb*1048576 cast to u64 saturates negative/NaN to zero and large values to max; secs remains f64, so NaN elapsed comparison never exceeds. Source model, not resource validation.

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.

### sampling_gap

try_wait precedes usage; short child can return with zero peak/cpu. Tree may change between /proc reads and duplicate PIDs are not deduplicated.

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.

### termination_order

Each fresh tree enumerated reverse for TERM then after five seconds KILL; discovered descendants can differ. Return -9 for limit regardless of actual child code.

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.

### logging_failure

Append open/write errors occur after workload completion/termination and prevent intended process::exit; no mkdir or structured JSON serializer guarantees valid output for all float estimates.

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 exercises actual pure flag. Monitor, signals, CLI workload and logging remain source-derived; no real heavy job launched.

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.

### evidence

#### Wave33 evidence — 2026-10-31

Across this nine-source slice, 14 exact native names passed twice in debug and twice in release (56 runs); sorted target-qualified outcomes agree. Six compiled behavior controls fail named assertions and exact restored bytes pass again. One exploratory parser-count control failed by unwrap panic; it was restored and replaced by a form-column assertion control. No assertion-only control is counted.

Nine syntax projections were generated twice and byte compared. Production source prefixes match the base exactly; four files append only formatted cfg(test) blocks. Local groupants validation reports valid=true, zero diagnostics. Counts: nine source roots, ten scoped children, 114 typed views.

See tests.md for this source's precise executed or representation-only coverage. Native evidence does not apply to ignored live teacher or lesson execution. No teacher/API, model/corpus, learning or benchmark CLI was run. Receipts retain numeric statuses, exact names, log/source hashes, original backups, unique mutation replacements and restoration assertions. The external bundle is named octopus-wave33-cycle-2026-10-31.

### invariant-and-cost

#### Invariant and cost

flag parses first occurrence only, admits nonfinite/negative f64. Empty command after -- indexes cmd[0] and can panic. /proc sampling is best effort, not complete accounting; assumed 100 ticks/second. Log parent directory is not created.

Each sample reads task-child/status/stat files across enumerated process tree, O(processes+proc bytes); one-second polling, five-second kill delay, unbounded workload cost. No universal resource guarantee.

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%.
