+# 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
+
+---
+
+## Steps
+
+### Step 819: Porting review board model (12 tests)
+### Step 820: Ambiguity triage UI model and API (10 tests)
+### Step 821: Waiver policy packet (`temporary/permanent/scoped`) (10 tests)
+### Step 822: Reviewer decision ledger integration (10 tests)
+### Step 823: Policy pack system (`safe-first`, `interop-first`, custom) (10 tests)
+### Step 824: Decision replay and reproducibility checker (10 tests)
+### Step 825: Feedback-to-adapter tuning hooks (8 tests)
+### Step 826: `whetstone_review_porting_decision` MCP tool (8 tests)
+### Step 827: Governance and audit report bundle (8 tests)
+### Step 828: Sprint 59 integration summary + regression (8 tests)
+

+
+## Governance Rule
+
+- Every blocked/waived gate must have attributable reviewer rationale.
