Optional Output Mappings

Release v0.4.0

This release focuses on improving repository quality gates and expanding workflow mapping flexibility with optional input/output support.

✨ Highlights

Optional input/output mappings

Workflows can now define optional mappings using a ? suffix. This makes integrations more flexible by allowing mappings that may or may not exist at runtime without causing failures.

Example conceptually:

{
    "input_mapping": {
        "customerId?": "workflow.customer.id"
    }
}

This is especially useful when:

• working with partially available payloads
• integrating external systems with inconsistent schemas
• evolving workflows incrementally without breaking compatibility

Improved repository quality checks

Presubmit validation and lint enforcement were added to improve contributor experience and maintain repository consistency.

This includes:

• automated lint validation
• repository presubmit checks
• cleanup of existing lint issues before enforcement

Contributed by lokewate in PRs #18 and #19.

🔧 What's Changed

• Added presubmit checks for the repository
• Fixed existing lint issues before enabling lint enforcement
• Added support for optional input/output mappings using ? suffix syntax
