## Features

* **Text masking** — 4 strategies: redact, replace, token, hash
* **Quality metrics** — grade (A–D), score, noise ratio, language detection
* **Compliance summary** — KVKK / GDPR risk categories
* **LLM preparation** — `redact_for_llm()` one-liner, token estimation
* **LangChain & LlamaIndex** — drop-in loaders with quality filtering
* **Zero dependencies** — pure Python / pure JavaScript, no heavy ML models

## Quick example

<CodeGroup>
  ```python Python theme={null}
  from flexorch_audit import audit

  result = audit("""
    Invoice from Acme Ltd.
    Contact: john.doe@acme.com
    IBAN: TR33 0006 1005 1978 6457 8413 26
    Amount: €12,500
  """)

  print(result["quality_grade"])        # "A"
  print(result["pii_summary"]["count"]) # 2
  print(result["detected_language"])    # "en"
  ```

  ```javascript JavaScript theme={null}
  import { audit } from '@flexorch/audit';

  const result = await audit(`
    Invoice from Acme Ltd.
    Contact: john.doe@acme.com
    IBAN: TR33 0006 1005 1978 6457 8413 26
    Amount: €12,500
  `);

  console.log(result.qualityGrade);         // "A"
  console.log(result.piiSummary.count);     // 2
  console.log(result.detectedLanguage);     // "en"
  ```

## Relationship to FlexOrch platform

`flexorch-audit` contains the core detection logic used by the FlexOrch platform. The platform adds:

* Structured extraction for 9 document types
* Managed pipeline (async jobs, job history)
* Dataset building and export
* Cloud connectors (S3, GCS, Azure)
* Compliance reports and audit trail
* Team management

Use `flexorch-audit` if you want detection in your own pipeline. Use the FlexOrch platform if you want the full managed workflow.
