# Sprint 198 Plan: Long-Range Edit Reliability III (Execution)

## Context
Need transactional execution engine for long-range plans.

## Goals
1. Execute long-range plans transactionally
2. Support partial failure rollback
3. Persist deterministic execution traces

## Steps

### Step 2029: Transactional long-range executor (10 tests)
Execute graph-ordered edits with transaction boundaries.

### Step 2030: Partial failure rollback engine (10 tests)
Rollback to nearest deterministic checkpoint on failure.

### Step 2031: Multi-file conflict detection during execution (8 tests)
Detect and classify cross-file edit conflicts.

### Step 2032: Execution trace and recovery packet export (8 tests)
Persist per-node execution and rollback traces.

### Step 2033: Sprint 198 Integration Summary (8 tests)
Add `editor/src/Sprint198IntegrationSummary.h`.

## Architecture Gate
- Long-range execution must be transaction-safe with deterministic rollback.
