## Issues in Code You Touched (Should Fix)

**None**

The changed files do not introduce or modify any dependency usage:

| File | Dependency Impact |
|------|-------------------|
| `src/core/interfaces.ts` | Interface definitions only - no imports |
| `src/implementations/dependency-repository.ts` | Uses existing `better-sqlite3` - no changes |
| `src/implementations/task-repository.ts` | Uses existing `better-sqlite3` - no changes |
| `src/services/handlers/dependency-handler.ts` | No dependency changes |
| `tests/fixtures/test-doubles.ts` | Test mocks only |
| `tests/**/*.test.ts` | Test files - no production dependencies |

---

## Pre-existing Issues (Not Blocking)

### Outdated Dependencies

The following packages have newer versions available:

| Package | Current | Wanted | Latest | Type | Severity |
|---------|---------|--------|--------|------|----------|
| `@modelcontextprotocol/sdk` | 1.24.3 | 1.25.1 | 1.25.1 | prod | LOW |
| `better-sqlite3` | 12.4.1 | 12.5.0 | 12.5.0 | prod | LOW |
| `simple-git` | 3.28.0 | 3.30.0 | 3.30.0 | prod | LOW |
| `zod` | 3.25.76 | 3.25.76 | **4.2.1** | prod | MEDIUM |
| `@types/node` | 24.3.0 | 24.10.4 | 25.0.3 | dev | INFO |
| `typescript` | 5.9.2 | 5.9.3 | 5.9.3 | dev | INFO |
| `tsx` | 4.20.4 | 4.21.0 | 4.21.0 | dev | INFO |
| `vitest` | 3.2.4 | 3.2.4 | **4.0.16** | dev | INFO |

| `@vitest/ui` | 3.2.4 | 3.2.4 | **4.0.16** | dev | INFO |

**Notes:**
- `zod@4.x` is a major version upgrade - requires migration assessment
- `vitest@4.x` is a major version upgrade - may have breaking changes
- Minor/patch updates for `better-sqlite3`, `simple-git` recommended

## Analysis of Changed Files

### Interface Changes (`src/core/interfaces.ts`)

**Lines Added**: 18 (TaskRepository) + 18 (DependencyRepository)

```typescript
// TaskRepository additions
findAll(limit?: number, offset?: number): Promise<Result<readonly Task[]>>;
findAllUnbounded(): Promise<Result<readonly Task[]>>;
count(): Promise<Result<number>>;

// DependencyRepository additions
findAll(limit?: number, offset?: number): Promise<Result<readonly TaskDependency[]>>;
findAllUnbounded(): Promise<Result<readonly TaskDependency[]>>;
count(): Promise<Result<number>>;
```

**Dependency Impact**: None - pure TypeScript interface definitions.

### Implementation Changes

**`src/implementations/task-repository.ts`**:
- New prepared statement `countStmt`
- Modified `findAll()` to support pagination
- New `findAllUnbounded()` method
- New `count()` method

**`src/implementations/dependency-repository.ts`**:
- New prepared statement `countStmt`
- Renamed `findAllStmt` to `findAllUnboundedStmt`
- Modified `findAll()` to support pagination
- New `findAllUnbounded()` method
- New `count()` method

**Dependency Impact**: None - uses existing `better-sqlite3` APIs.

### Handler Changes (`src/services/handlers/dependency-handler.ts`)

```diff
-    const allDepsResult = await dependencyRepo.findAll();
+    const allDepsResult = await dependencyRepo.findAllUnbounded();
```

**Dependency Impact**: None - internal method call change.

## Recommendations

### For This PR

1. **APPROVED** - No dependency issues introduced

### For Future Work (Separate PRs)

1. **LOW PRIORITY**: Update minor/patch versions
   ```bash
   npm update @modelcontextprotocol/sdk better-sqlite3 simple-git tsx typescript
   ```

2. **MEDIUM PRIORITY**: Evaluate `zod@4.x` migration
   - Review [Zod 4.0 migration guide](https://github.com/colinhacks/zod/releases)
   - Significant API changes may require code updates

3. **LOW PRIORITY**: Evaluate `vitest@4.x` migration (dev only)
   - Review breaking changes before upgrading
