[grishabh96]

Summary

This PR introduces an AI-assisted settlement readiness workflow designed to reduce ambiguity-driven settlement disputes for Vs deals before settlement night.

The solution focuses on improving trust, transparency, and operational clarity during the settlement process rather than fully automating settlement calculations.

Key Additions

• AI-assisted deal readiness workflow for parsing freeform deal notes
• Ambiguity detection for unclear deductions, recoups, and deal assumptions
• Clarification workflow to help bookers proactively resolve ambiguous terms with agents
• Settlement workspace with editable and transparent calculations(Beta version)
• Line-by-line settlement breakdowns designed to mirror spreadsheet-style trust and flexibility(Beta version)
• Human-in-the-loop workflow where users retain final control over interpretations and settlement decisions

Scope Decisions

The implementation intentionally focuses on Vs deals, as they represented the highest concentration of settlement disputes while keeping the scope manageable for the prototype.

The workflow prioritizes:

• transparency over autonomous automation
• upstream ambiguity resolution over downstream dispute handling
• editable calculations over rigid system-generated outcomes(Beta version)

Future Opportunities

Potential future extensions include:

• collaborative pre-settlement review workflows
• structured deal confirmations
• receipt-level provenance and audit trails
• support for additional deal structures
