## SHOULD FIX - Issues in Code You Touched (2)

### SF-1: TASK-DEPENDENCIES.md - Stale Line Numbers for Other Methods

**File**: `/workspace/delegate/docs/TASK-DEPENDENCIES.md`
**Lines**: 705-707

**Issue**: While you correctly updated the `wouldCreateCycle` line reference (704), the other line references in the same section were not verified:

```markdown
- Dependency-aware queueing: `src/services/handlers/queue-handler.ts:63` (handleTaskPersisted)
- Dependency resolution: `src/services/handlers/dependency-handler.ts:199` (resolveDependencies)
- Task unblocking: `src/services/handlers/queue-handler.ts:306` (handleTaskUnblocked)
```

**Actual Line Numbers**:
- `handleTaskPersisted`: Line 63 (CORRECT)
- `resolveDependencies`: Line 344 (INCORRECT - doc says 199)
- `handleTaskUnblocked`: Line 306 (CORRECT)

**Severity**: MEDIUM - The `resolveDependencies` line reference is outdated.

**Fix**: Update line 706 to:
```markdown
- Dependency resolution: `src/services/handlers/dependency-handler.ts:344` (resolveDependencies)
```

### SF-2: Missing Documentation for Settling Workers Feature

**Files Affected**:
- `/workspace/delegate/docs/FEATURES.md`
- `/workspace/delegate/docs/architecture/TASK_ARCHITECTURE.md`

**Issue**: The settling workers tracking feature is documented in CHANGELOG.md but missing from:

1. **FEATURES.md** - The "Autoscaling & Resource Management" section (lines 25-37) does not mention:
   - `recordSpawn()` method for settling worker tracking
   - 15-second settling window
   - Protection against spawn burst overload

2. **TASK_ARCHITECTURE.md** - No documentation of the settling workers mechanism in the resource monitoring sections.

**New Code Without Documentation**:
```typescript
// src/implementations/resource-monitor.ts (lines 27-31)
// SETTLING WORKERS TRACKING (Issue: load average is lagging indicator)
// Workers that were recently spawned but may not yet be reflected in system metrics
// This prevents spawning too many workers before load average catches up
private readonly SETTLING_WINDOW_MS = 15000; // 15 seconds for worker to "settle"
private recentSpawnTimestamps: number[] = [];

// src/core/interfaces.ts (lines 51-55)
/**
 * Record a spawn event for settling worker tracking
 * Call immediately after spawning to track workers during their settling period
 * (before they appear in system metrics like load average)
 */
recordSpawn?(): void;
```

**Severity**: MEDIUM - New public interface method and performance feature undocumented.

**Fix**: Add to FEATURES.md under "Autoscaling & Resource Management":
```markdown
### Spawn Burst Protection (v0.3.1)
- **Settling Workers Tracking**: Tracks recently spawned workers for 15 seconds
- **Load Average Compensation**: Projects resource usage before system metrics update
- **recordSpawn() Interface**: ResourceMonitor method to record spawn events
- **minSpawnDelayMs**: Increased from 50ms to 1000ms for additional protection
```

## INFO - Pre-existing Issues (4)

### PI-1: FEATURES.md Version Header Outdated

**File**: `/workspace/delegate/docs/FEATURES.md`
**Line**: 1

**Issue**: Header says "Delegate v0.2.1 - Current Features" but v0.3.0 features are documented.

**Current**:
```markdown
# Delegate v0.2.1 - Current Features
```

**Should Be**:
```markdown
# Delegate v0.3.x - Current Features
```

**Severity**: LOW - Cosmetic issue only.

---

### PI-2: TASK_ARCHITECTURE.md - Stale Line Numbers

**File**: `/workspace/delegate/docs/architecture/TASK_ARCHITECTURE.md`
**Lines**: Various

**Issue**: Several line number references in this file are likely outdated beyond what was fixed in this branch:

- Line 19: `Lines 28-82` for Task interface
- Line 74: `Lines 20-26` for TaskStatus enum
- Line 718: `Lines 73-110` for Cycle Detection (should be 240-280 per your fix)

**Severity**: LOW - The referenced file sections exist but line numbers may drift.

**Recommendation**: Consider removing specific line numbers or using function/class names only for more maintainable documentation.

---

### PI-3: CHANGELOG.md - Inconsistent Version Sections

**File**: `/workspace/delegate/CHANGELOG.md`
**Lines**: 302-323

**Issue**: The "Development Versions" section at the bottom still references:
- "v0.3.0 - Task Dependencies (Planned Q4 2025)" - But v0.3.0 is already released
- "v0.4.0 - Distributed Processing (Planned Q1 2026)"
- "v0.5.0 - Advanced Orchestration (Planned Q2 2026)"

This section conflicts with the actual v0.3.0 release section above it.

**Severity**: LOW - Misleading but in a rarely-read section.

---

### PI-4: Missing Configuration Validation Warning Documentation

**File**: `/workspace/delegate/docs/FEATURES.md` or README.md

**Issue**: The new configuration validation warning feature (added in this branch) is only documented in CHANGELOG.md:

```typescript
// src/core/configuration.ts (lines 134-141)
// SECURITY: Log warning when config validation fails (don't silently fallback)
const errors = parseResult.error.errors.map(e =>
  `  - ${e.path.join('.')}: ${e.message}`
).join('\n');
console.warn(
  `[Delegate] Configuration validation failed, using defaults:\n${errors}`
);
```

This behavior change (no longer silent fallback) should be documented in FEATURES.md under "Configuration System".

**Severity**: LOW - Behavior is documented in CHANGELOG, just not in feature docs.

## Recommendations

### Before Merge (SHOULD FIX)

1. **Fix SF-1**: Update the stale `resolveDependencies` line reference in TASK-DEPENDENCIES.md from 199 to 344.

2. **Fix SF-2**: Add settling workers documentation to FEATURES.md. This is a user-visible performance feature that affects spawn behavior.

### After Merge (OPTIONAL)

3. Update FEATURES.md version header (PI-1)
4. Review and update TASK_ARCHITECTURE.md line numbers holistically (PI-2)
5. Clean up CHANGELOG.md "Development Versions" section (PI-3)
6. Document configuration validation warning in FEATURES.md (PI-4)

---

## Conclusion

The documentation changes in this branch are accurate and correctly update the stale line number references for the `wouldCreateCycle` method. The deep copy pattern example is correct.

Two should-fix issues were identified:
1. One additional stale line number in the same section that was touched
2. Missing feature documentation for the new settling workers tracking

Four informational pre-existing issues were identified that are not related to this branch's changes.

**Final Assessment**: The branch is ready to merge with minor documentation improvements recommended.
