# Sprint 59 Plan: Human-in-the-Loop Porting Workspace and Governance

## Context

As language count rises, review workflow quality determines practical adoption.
Sprint 59 strengthens human governance for ambiguous/high-risk transformations.

## Goals

1. Provide first-class review UX for semantic ambiguities and waivers
2. Add policy packs per organization/team
3. Track decision history for reproducibility and model improvement
4. Close loop between reviewer decisions and adapter policies
