+# Sprint 110 Plan: Epoch 2 Stabilization and Roadmap Renewal
+
+## Context
+
+Sprint 110 closes the first 10-sprint block of Epoch 2 with stabilization,
+scorecard review, and roadmap renewal for the next block.
+
+---
+
+## Goals
+
+1. Re-baseline system health after Sprints 101-109 changes
+2. Validate KPI movement against epoch targets
+3. Publish next-block roadmap priorities and constraints
+4. Confirm governance and safety invariants remain intact
+
+---
+
+## Steps
+
+### Step 1329: Epoch block health re-baseline model (12 tests)
+### Step 1330: KPI delta analysis engine for block review (10 tests)
+### Step 1331: Target attainment checker against epoch goals (10 tests)
+### Step 1332: Next-block priority planner and constraint binder (10 tests)
+### Step 1333: Governance and safety invariant revalidation pass (10 tests)
+### Step 1334: Renewal risk register generation (8 tests)
+### Step 1335: `whetstone_get_epoch_block_status` MCP tool (8 tests)
+### Step 1336: `whetstone_publish_next_block_plan` MCP tool (8 tests)
+### Step 1337: Epoch renewal publication bundle (8 tests)
+### Step 1338: Sprint 110 integration summary + full-program regression (8 tests)
+

+
+## Renewal Rule
+
+- Next-block launch requires passed invariant revalidation and block scorecard review.
