# Endpoint triage and process context

Combine parent chains, artifact identity, behavior and sensor coverage before judging a process name.

## Preserve the process tree

A process name can be changed and may also have legitimate uses. Collect parent/child relationships, initiating identity, path, hash, time and source-event ID. Command lines can contain secrets or personal data; scope access and report display. Distinguish acquired records from later interpretation. This kit executes no process or command and reads only synthetic record fields.

## Signature and behavior

A valid signature does not establish intended use. Assess publisher, path, hash and behavior in business context. Legitimate administration tools can be abused. Replace binary judgments such as signed-safe or odd-name-malicious with behavior supported by independent records. Actual memory/disk acquisition requires authorized specialists, suitable tools and recorded procedures; this timeline does not acquire either.

## Silent sensors and persistence

An alert-free period is not evidence when the sensor was offline. Verify health, time window and retention coverage. Stopping a process does not remove persistence, tasks, services or stolen identity. Connect related-device/identity scope and support cleanup with independent validation. Collection and containment can affect each other; record the incident lead’s rationale when balancing evidence loss against ongoing harm.

## Harbor-17 process record

endpoint-export reports report-viewer but lacks parent-chain and sensor-health data. Sharing a second with a network event does not prove process-to-network linkage. Request additional process/session/device references. Equal timestamps retain supplied order in the desk, not proven real-world order. Before converting stopped-process status into closure, complete persistence, identity and coverage questions.

## Working sequence

1. Preserve process and device context.
2. Link parent, artifact and behavior.
3. Verify sensor and time coverage.
4. Review persistence and identity impact.
5. Independently validate cleanup claims.

## 1. Only a process name

Stopping a process does not complete parent-chain, artifact-link or persistence review. A name alone proves neither malicious intent nor cleanup.

This code is a local policy model; it does not replace target/cluster testing.

### Weak implementation
```js
s=>s.processStopped
```

### Corrected implementation
```js
s=>s.processStopped&&s.parentChainPreserved&&s.artifactLinked&&s.persistenceReviewed
```

        "artifactLinked": false,
        "persistenceReviewed": false
      },

    },

    }
  ],
  "after": [
    {
      "name": "supported-case",
      "input": {
        "processStopped": true,
        "parentChainPreserved": true,
        "artifactLinked": true,
        "persistenceReviewed": true
      },
      "expected": true,

    {

    }
  ]
}
```

## 2. Is signed always safe?

A valid signature can coexist with abuse. Verify expected publisher, behavior and business use separately before a safe-use decision.

This code is a local policy model; it does not replace target/cluster testing.

### Weak implementation
```js
s=>s.signatureValid
```

### Corrected implementation
```js
s=>s.signatureValid&&s.publisherExpected&&s.behaviorReviewed&&s.businessUseVerified
```

### Synthetic input and actual model output
```json
{
  "before": [
    {
      "name": "supported-case",
      "input": {
        "signatureValid": true,
        "publisherExpected": true,
        "behaviorReviewed": true,
        "businessUseVerified": true
      },
      "expected": true,
      "observed": true,
      "matched": true
    },
    {
      "name": "signed-but-abused",
      "input": {
        "signatureValid": true,
        "publisherExpected": true,
        "behaviorReviewed": false,
        "businessUseVerified": false
      },
      "expected": false,
      "observed": true,
      "matched": false
    },
    {
      "name": "unknown-publisher",
      "input": {
        "signatureValid": true,
        "publisherExpected": false,
        "behaviorReviewed": true,
        "businessUseVerified": true
      },
      "expected": false,
      "observed": true,
      "matched": false
    }
  ],
  "after": [
    {
      "name": "supported-case",
      "input": {
        "signatureValid": true,
        "publisherExpected": true,
        "behaviorReviewed": true,
        "businessUseVerified": true
      },
      "expected": true,
      "observed": true,
      "matched": true
    },
    {
      "name": "signed-but-abused",
      "input": {
        "signatureValid": true,
        "publisherExpected": true,
        "behaviorReviewed": false,
        "businessUseVerified": false
      },
      "expected": false,
      "observed": false,
      "matched": true
    },
    {
      "name": "unknown-publisher",
      "input": {
        "signatureValid": true,
        "publisherExpected": false,
        "behaviorReviewed": true,
        "businessUseVerified": true
      },
      "expected": false,
      "observed": false,
      "matched": true
    }
  ]
}
```

## 3. No alerts

noAlerts becomes meaningful with a healthy sensor and covered window. Silence alone is not an automatic clean result without independent evidence.

This code is a local policy model; it does not replace target/cluster testing.

### Weak implementation
```js
s=>s.noAlerts
```

### Corrected implementation
```js
s=>s.noAlerts&&s.sensorHealthy&&s.windowCovered&&s.independentEvidence
```

### Synthetic input and actual model output
```json
{
  "before": [
    {
      "name": "supported-case",
      "input": {
        "noAlerts": true,
        "sensorHealthy": true,
        "windowCovered": true,
        "independentEvidence": true
      },
      "expected": true,
      "observed": true,
      "matched": true
    },
    {
      "name": "sensor-offline",
      "input": {
        "noAlerts": true,
        "sensorHealthy": false,
        "windowCovered": false,
        "independentEvidence": false
      },
      "expected": false,
      "observed": true,
      "matched": false
    },
    {
      "name": "missing-window",
      "input": {
        "noAlerts": true,
        "sensorHealthy": true,
        "windowCovered": false,
        "independentEvidence": true
      },
      "expected": false,
      "observed": true,
      "matched": false
    }
  ],
  "after": [
    {
      "name": "supported-case",
      "input": {
        "noAlerts": true,
        "sensorHealthy": true,
        "windowCovered": true,
        "independentEvidence": true
      },
      "expected": true,
      "observed": true,
      "matched": true
    },
    {
      "name": "sensor-offline",
      "input": {
        "noAlerts": true,
        "sensorHealthy": false,
        "windowCovered": false,
        "independentEvidence": false
      },
      "expected": false,
      "observed": false,
      "matched": true
    },
    {
      "name": "missing-window",
      "input": {
        "noAlerts": true,
        "sensorHealthy": true,
        "windowCovered": false,
        "independentEvidence": true
      },
      "expected": false,
      "observed": false,
      "matched": true
    }
  ]
}
```
