"""
Enterprise ALM & TMS Sync Bridge (Jira / Xray / Zephyr / TestRail)
------------------------------------------------------------------
Bi-directional synchronization bridge connecting autonomous QA agents with
Enterprise Test Management Systems:
  1. Pull Mode (Inward):
     - Pulls User Stories, Acceptance Criteria (Given-When-Then / Gherkin),
       and Test Cases directly from Jira Issues, Xray, or TestRail.
     - Formats them into standardized prompt contexts for Clean POM test generation.
  2. Push Mode (Outward Defect Reporter):
     - Automatically creates detailed Bug Tickets on Jira when tests fail.
     - Attaches failure stack traces, repro steps, links to Screenshots/FAILED_*.png,
       video recordings, console error logs, and environment metadata.
  3. Execution Run Sync:
     - Reports bulk test execution outcomes (PASS / FAIL / BLOCKED, execution time)
       back to Jira Xray Test Execution or TestRail Run.
  4. Offline / Mock & Dry-Run Support:
     - Fully functional offline simulation for CI pipelines and test suites without
       requiring live enterprise credentials.
