# Sprint 196 Plan: Long-Range Edit Reliability I (Contracts)

## Context
Long-range multi-file edits need explicit deterministic contracts.

## Goals
1. Define long-range edit contract schema
2. Require file-set and dependency closure metadata
3. Add blocker classes for incomplete long-range specs

## Steps

### Step 2019: Long-range edit contract schema (10 tests)
Add schema fields for multi-file edit intent, scope, and constraints.

### Step 2020: Dependency closure metadata extraction (10 tests)
Compute required file/symbol closure for planned edits.

### Step 2021: Contract completeness validator (8 tests)
Reject long-range tasks missing closure-critical fields.

### Step 2022: Long-range blocker taxonomy (8 tests)
Add deterministic blockers for under-specified long-range edits.

### Step 2023: Sprint 196 Integration Summary (8 tests)
Add `editor/src/Sprint196IntegrationSummary.h`.

## Architecture Gate
- Long-range edit tasks must be rejected unless contract-complete.
