# Sprint 197 Plan: Long-Range Edit Reliability II (Planning)

## Context
Contracts alone are insufficient; planner must produce deterministic edit graph.

## Goals
1. Build deterministic long-range edit planner
2. Add graph-based edit ordering and checkpoints
3. Expose planner output to execution pipeline

## Steps

### Step 2024: Long-range edit graph planner (10 tests)
Construct ordered edit graph with dependency edges.

### Step 2025: Checkpoint and rollback node insertion (10 tests)
Insert deterministic checkpoints into long edit sequences.

### Step 2026: Planner-executor handoff packet (8 tests)
Emit machine-readable plan for execution tools.

### Step 2027: Plan fingerprinting and replay checks (8 tests)
Add stable plan fingerprint and replay verification.

### Step 2028: Sprint 197 Integration Summary (8 tests)
Add `editor/src/Sprint197IntegrationSummary.h`.

## Architecture Gate
- Long-range edit plans must be ordered, checkpointed, and replayable.
