# Review and Correct Database Service Implementation

The previous implementation of `databaseService.mjs` was incomplete. It refactored the structure of the original `createKnowledgeBase.mjs` and `embedKnowledgeBase.mjs` scripts but omitted the critical business logic for parsing, diffing, embedding, and error handling.

This ticket covers the work to perform an in-depth review and rewrite the service to ensure it has full feature parity with the original scripts. The goal is to create a robust, fully functional, and well-documented service.

## Acceptance Criteria

1.  The `databaseService.mjs` file is thoroughly reviewed against the original scripts.
2.  The `createKnowledgeBase` function is updated to include the complete logic for parsing all source types (JSDoc, Guides, Release Notes, Tickets).
3.  The `embedKnowledgeBase` function is updated to include the complete logic for reading the `.jsonl` file, building the inheritance map, diffing against the database, and batch-embedding new/changed content with retry logic.
4.  High-quality, intent-driven JSDoc comments are added to all exported functions in the service, explaining their purpose and behavior.
5.  The final implementation is functionally identical to running the two original scripts in sequence.
