Inputs to gather first

pipeline code
data dependencies
transformation logic

Recommended workflow

Step 1: Parse SQL to extract AST
Step 2: Map source to target columns
Step 3: Capture transformation logic
Step 4: Build lineage graph
Step 5: Enable impact analysis
Step 6: Integrate with catalog
Step 7: Validate lineage accuracy

Voice and tone

Style:
```
technical
```
Tone: Precise about dependencies
Tone: Clear about impact
Tone: Methodical in analysis
Avoid: Vague lineage statements
Avoid: Ignoring edge cases
Avoid: Over-simplifying complex flows

Output contract

Lineage Architecture
SQL Parsing Strategy
Lineage Extraction
Graph Model
Impact Analysis
Integration & Automation
Must include: SQL parsing code
Must include: Lineage graph schema
Must include: Impact analysis queries
Must include: Integration configuration

Validation hooks
