# Phase 2 Merge Strategy: PR #265 onto PR #272

**Document Version**: 1.0  
**Date**: 2026-02-11  
**Author**: Merge Strategist Agent  
**Status**: Ready for Execution

---

## Executive Summary

This document provides a detailed merge strategy for integrating PR #265 (MCP relationship tools + CLI enhancements) onto PR #272 (critical compilation fixes + server restructuring).

### Key Conflict Summary
- **Primary Conflict Type**: Path rename conflict with file modifications
- **Affected Files**: 2 files requiring manual intervention
- **Low-Risk Changes**: ~80 files can be applied automatically
- **Risk Level**: LOW (conflicts are mechanical, not semantic)

---

## Section 1: Recommended Strategy

### 1.1 Strategy Selection: Option B - Integration Branch

**Selected Strategy**: Create integration branch from PR #272, manually apply PR #265 changes

### 1.2 Justification

| Option | Pros | Cons | Verdict |
|--------|------|------|---------|
| **A: Merge PR #272 first, then cherry-pick** | Clean history | Cherry-picking 30+ features individually is error-prone | ❌ Rejected |
| **B: Integration branch from PR #272, manual apply** | Full control, preserves PR #272 fixes, can validate incrementally | Requires more manual steps | ✅ **Selected** |
| **C: Rebase PR #265 onto PR #272** | Linear history | Complex due to directory rename, high risk of conflicts | ❌ Rejected |

**Rationale for Option B**:
1. **Safety**: PR #272 contains critical fixes that must be preserved
2. **Control**: Manual application allows precise control over each change
3. **Validation**: Can build and test after each major step
4. **Risk Mitigation**: Easy to rollback if issues arise
5. **Documentation**: Each step is clearly documented for auditability

---

## Section 2: Step-by-Step Execution Plan

### Phase 1: Preparation (Steps 1-5)

#### Step 1: Create Integration Branch
```bash
# Ensure we're on a clean state
git checkout main
git fetch origin

# Create integration branch from PR #272
git checkout -b integration/pr265-onto-pr272 pr-272

# Verify we're at the right commit
git log --oneline -1
# Expected: d2691de or later from pr-272
```

**Validation**: Run build to confirm PR #272 baseline
```bash
cargo build --all 2>&1 | tail -20
echo "Exit code: $?"
```
**Expected**: Zero compilation errors, zero clippy warnings

**Rollback**: 
```bash
git checkout main
git branch -D integration/pr265-onto-pr272
```

---

#### Step 2: Document Baseline State
```bash
# Create a baseline report
./scripts/quality-gates.sh > /tmp/baseline_quality_report.txt 2>&1
cargo test --all 2>&1 | tail -50 > /tmp/baseline_test_report.txt

# Record current state
git rev-parse HEAD > /tmp/baseline_commit.txt
git diff --stat pr-272 > /tmp/baseline_changes.txt
```

**Expected Outputs**:
- baseline_quality_report.txt: All quality gates pass
- baseline_test_report.txt: 717 tests passing (1 pre-existing embedding failure acceptable)
- baseline_commit.txt: Current PR #272 commit hash

---

#### Step 3: Analyze PR #265 Changes by Category

Create a categorized list of changes to apply:

```bash
# Create a changes inventory
git diff --name-only pr-272...pr-265 | sort > /tmp/pr265_all_changes.txt

# Categorize
echo "=== SERVER FILES (Manual Merge Required) ==="
git diff --name-only pr-272...pr-265 | grep "do-memory-mcp/src/bin/server/"

echo "=== CLI FILES (Auto-apply Safe) ==="
git diff --name-only pr-272...pr-265 | grep "do-memory-cli/src/"

echo "=== CORE FILES (Check for conflicts) ==="
git diff --name-only pr-272...pr-265 | grep "do-memory-core/src/"

echo "=== TEST FILES (Auto-apply Safe) ==="
git diff --name-only pr-272...pr-265 | grep "tests/"

echo "=== PLAN/DOC FILES (Auto-apply Safe) ==="
git diff --name-only pr-272...pr-265 | grep "plans/"
```

**Expected Categories**:
- **Critical (Manual)**: 2 files in server_impl/
- **CLI Features**: ~8 files in do-memory-cli/
- **Core Changes**: 4 files in do-memory-core/ (verify no conflicts)
- **Tests**: ~8 files in tests/
- **Plans/Docs**: ~50+ files (safe to auto-apply)

---

#### Step 4: Backup Critical Files
```bash
# Backup the files we'll modify manually
cp do-memory-mcp/src/bin/server_impl/handlers.rs /tmp/handlers_backup.rs
cp do-memory-mcp/src/bin/server_impl/tools.rs /tmp/tools_backup.rs

cp do-memory-mcp/src/bin/server_impl/handlers.rs /tmp/handlers_new.rs
cp do-memory-mcp/src/bin/server_impl/tools.rs /tmp/tools_new.rs
```

---

#### Step 5: Create Merge Checklist
Create a physical checklist to track progress:

```bash
cat > /tmp/merge_checklist.md << 'EOF'
# Merge Checklist - PR #265 onto PR #272

## Phase 1: Preparation ✅
- [ ] Step 1: Integration branch created
- [ ] Step 2: Baseline documented
- [ ] Step 3: Changes categorized
- [ ] Step 4: Critical files backed up
- [ ] Step 5: Checklist created

## Phase 2: Safe Changes (Steps 6-9)
- [ ] Step 6: CLI commands/relationships/ applied
- [ ] Step 7: CLI commands/tag/ applied
- [ ] Step 8: CLI main.rs/mod.rs applied
- [ ] Step 9: Core changes applied

## Phase 3: Critical Merge (Steps 10-13)
- [ ] Step 10: Tools.rs modifications
- [ ] Step 11: Handlers.rs modifications
- [ ] Step 12: Build verification
- [ ] Step 13: Test verification

## Phase 4: Finalization (Steps 14-17)
- [ ] Step 14: Remaining files applied
- [ ] Step 15: Full test suite
- [ ] Step 16: Quality gates
- [ ] Step 17: Documentation update
EOF
```

---

### Phase 2: Safe Changes Application (Steps 6-9)

These changes have no conflicts with PR #272 and can be applied directly.

#### Step 6: Apply CLI Relationships Module
```bash
# Create the relationships directory if it doesn't exist
mkdir -p do-memory-cli/src/commands/relationships

# Extract files from PR #265
git show pr-265:do-memory-cli/src/commands/relationships/mod.rs > do-memory-cli/src/commands/relationships/mod.rs
git show pr-265:do-memory-cli/src/commands/relationships/core.rs > do-memory-cli/src/commands/relationships/core.rs
git show pr-265:do-memory-cli/src/commands/relationships/types.rs > do-memory-cli/src/commands/relationships/types.rs

# Verify files were created
ls -la do-memory-cli/src/commands/relationships/

# Stage changes
git add do-memory-cli/src/commands/relationships/
```

**Validation**:
```bash
cargo check -p do-memory-cli 2>&1 | grep -E "(error|warning)" | head -20
```
**Expected**: No compilation errors

---

#### Step 7: Apply CLI Tag Module Changes
```bash
# Apply tag module changes (these modify existing files)
git show pr-265:do-memory-cli/src/commands/tag/core.rs > do-memory-cli/src/commands/tag/core.rs
git show pr-265:do-memory-cli/src/commands/tag/output.rs > do-memory-cli/src/commands/tag/output.rs
git show pr-265:do-memory-cli/src/commands/tag/tests.rs > do-memory-cli/src/commands/tag/tests.rs
git show pr-265:do-memory-cli/src/commands/tag/types.rs > do-memory-cli/src/commands/tag/types.rs

# Stage changes
git add do-memory-cli/src/commands/tag/
```

**Validation**:
```bash
cargo check -p do-memory-cli 2>&1 | grep -E "(error|warning)" | head -20
```

---

#### Step 8: Apply CLI Main and Mod Changes
```bash
# Apply main.rs changes
git show pr-265:do-memory-cli/src/main.rs > do-memory-cli/src/main.rs

# Apply commands/mod.rs changes
git show pr-265:do-memory-cli/src/commands/mod.rs > do-memory-cli/src/commands/mod.rs

# Stage changes
git add do-memory-cli/src/main.rs do-memory-cli/src/commands/mod.rs
```

**Validation**:
```bash
cargo check -p do-memory-cli 2>&1 | grep -E "(error|warning)" | head -20
```
**Expected**: No compilation errors (may have unused import warnings, acceptable)

---

#### Step 9: Apply Core Memory Changes
```bash
# Check what changes exist in do-memory-core
git diff pr-272 pr-265 -- do-memory-core/src/ > /tmp/memory_core_changes.patch

# Review the patch
cat /tmp/memory_core_changes.patch | head -100

# Apply if safe (no conflicts expected)
git show pr-265:do-memory-core/src/memory/core/struct_priv.rs > do-memory-core/src/memory/core/struct_priv.rs
git show pr-265:do-memory-core/src/memory/init.rs > do-memory-core/src/memory/init.rs
git show pr-265:do-memory-core/src/memory/types.rs > do-memory-core/src/memory/types.rs

# Stage changes
git add do-memory-core/src/
```

**Validation**:
```bash
cargo check -p do-memory-core 2>&1 | grep -E "(error|warning)" | head -20
```

---

### Phase 3: Critical Manual Merge (Steps 10-13)

This is the critical phase where we manually resolve the path rename conflict.

#### Step 10: Modify tools.rs (Server Implementation)

**File**: `do-memory-mcp/src/bin/server_impl/tools.rs`

**Changes Required**:
1. Rename `_handle_validate_no_cycles` → `handle_validate_no_cycles` (make pub)
2. Rename `_handle_get_topological_order` → `handle_get_topological_order` (make pub)
3. Remove `#[allow(dead_code)]` attributes
4. Add proper doc comments

**Execution**:

```bash
# First, let's see the current function signatures
grep -n "async fn _handle_validate_no_cycles\|async fn _handle_get_topological" do-memory-mcp/src/bin/server_impl/tools.rs

# Expected output shows the private functions with underscore prefix
```

**Manual Edit Required**:

Edit the file to change:

```rust
// FROM (current in PR #272):
#[allow(dead_code)]
async fn _handle_validate_no_cycles(

// TO (from PR #265):
/// Handle validate_no_cycles tool
/// 
/// Validates that the episode dependency graph has no cycles
pub async fn handle_validate_no_cycles(
```

And:

```rust
// FROM (current in PR #272):
#[allow(dead_code)]
async fn _handle_get_topological_order(

// TO (from PR #265):
/// Handle get_topological_order tool
/// 
/// Returns episodes in topological order based on dependencies
pub async fn handle_get_topological_order(
```

**Verification**:
```bash
# Check the changes
grep -n "pub async fn handle_validate_no_cycles\|pub async fn handle_get_topological" do-memory-mcp/src/bin/server_impl/tools.rs

# Build to verify
cargo check -p do-memory-mcp 2>&1 | grep -E "error" | head -20
```

**Expected**: No compilation errors

---

#### Step 11: Modify handlers.rs (Server Implementation)

**File**: `do-memory-mcp/src/bin/server_impl/handlers.rs`

**Changes Required**:
1. Add imports for `handle_get_topological_order` and `handle_validate_no_cycles`
2. Add tool routing in `handle_call_tool` match statement
3. SKIP batch execution routing (batch module was deleted in PR #272)

**Execution**:

**A. Add Imports**:

Find the import block in handlers.rs (around line 5-40):

```rust
use super::tools::{
    handle_add_episode_relationship,
    handle_add_episode_step,
    // ... other imports
    handle_get_dependency_graph,
    // ADD THESE TWO:
    handle_get_topological_order,
    handle_validate_no_cycles,
};
```

**B. Add Tool Routing in handle_call_tool**:

Find the match statement (around line 150-200) and add:

```rust
        "get_dependency_graph" => handle_get_dependency_graph(&mut server, params.arguments).await,
        // ADD THESE TWO CASES:
        "validate_no_cycles" => handle_validate_no_cycles(&mut server, params.arguments).await,
        "get_topological_order" => {
            handle_get_topological_order(&mut server, params.arguments).await
        }
        _ => {
```

**C. SKIP batch execution routing**:

The `handle_batch_execute` function references a batch module that was deleted in PR #272. DO NOT add batch routing for these tools.

**Verification**:
```bash
# Check imports
grep -n "handle_validate_no_cycles\|handle_get_topological_order" do-memory-mcp/src/bin/server_impl/handlers.rs

# Build to verify
cargo check -p do-memory-mcp 2>&1 | grep -E "error" | head -20
```

---

#### Step 12: Build Verification (Critical Checkpoint)

```bash
# Full build check
cargo build --all 2>&1 | tee /tmp/build_check_step12.log

# Check for errors
if grep -q "error\[" /tmp/build_check_step12.log; then
    echo "❌ BUILD FAILED - Errors detected"
    grep "error\[" /tmp/build_check_step12.log | head -10
else
    echo "✅ BUILD SUCCESSFUL"
fi
```

**Success Criteria**:
- Zero compilation errors
- Zero clippy warnings (or only pre-existing ones)

**If Build Fails**:
1. Review error messages
2. Check if imports are correct
3. Verify function signatures match
4. Compare with PR #265's original files

---

#### Step 13: Test Verification (Critical Checkpoint)

```bash
# Run tests for do-memory-mcp specifically
cargo test -p do-memory-mcp 2>&1 | tee /tmp/test_check_step13.log

# Check test results
if grep -q "test result: FAILED" /tmp/test_check_step13.log; then
    echo "❌ TESTS FAILED"
    grep "FAILED\|failures:" /tmp/test_check_step13.log | head -20
else
    echo "✅ TESTS PASSED"
fi
```

**Expected**:
- Most tests passing
- Any failures should be pre-existing (embedding similarity test)

---

### Phase 4: Finalization (Steps 14-17)

#### Step 14: Apply Remaining Safe Files

Apply the remaining files that don't have conflicts:

```bash
# Test files
git show pr-265:tests/e2e/cli_episode_workflow.rs > tests/e2e/cli_episode_workflow.rs
git show pr-265:tests/e2e/cli_pattern_workflow.rs > tests/e2e/cli_pattern_workflow.rs
git show pr-265:tests/e2e/cli_workflows.rs > tests/e2e/cli_workflows.rs
git show pr-265:tests/e2e/mcp_relationship_chain.rs > tests/e2e/mcp_relationship_chain.rs
git show pr-265:tests/e2e/mcp_tag_chain.rs > tests/e2e/mcp_tag_chain.rs
git show pr-265:tests/stability/mod.rs > tests/stability/mod.rs

# Stage test files
git add tests/

# Benchmark files (if any changes)
git show pr-265:benches/prepared_cache_benchmark.rs > benches/prepared_cache_benchmark.rs
git add benches/

# Plan files (documentation)
# These should be applied carefully to avoid overwriting newer plans
git diff pr-272 pr-265 --name-only | grep "plans/" | while read file; do
    echo "Reviewing: $file"
    # Only apply if it doesn't exist or is safe to update
    if [[ ! -f "$file" ]] || [[ "$file" == *".md"* ]]; then
        git show "pr-265:$file" > "$file" 2>/dev/null || true
    fi
done
```

---

#### Step 15: Full Test Suite

```bash
# Run complete test suite
cargo test --all 2>&1 | tee /tmp/full_test_suite.log

# Count results
echo "Test Summary:"
grep "test result:" /tmp/full_test_suite.log

# Check for failures
FAILURES=$(grep "test result: FAILED" /tmp/full_test_suite.log | wc -l)
if [ "$FAILURES" -gt 0 ]; then
    echo "❌ $FAILURES test suites failed"
    grep -A 5 "failures:" /tmp/full_test_suite.log | head -30
else
    echo "✅ All test suites passed"
fi
```

**Expected**:
- 717+ tests passing
- 1 pre-existing embedding similarity failure (acceptable)

---

#### Step 16: Quality Gates

```bash
# Run quality gates
./scripts/quality-gates.sh 2>&1 | tee /tmp/quality_gates_final.log

# Check results
if [ $? -eq 0 ]; then
    echo "✅ All quality gates passed"
else
    echo "❌ Quality gates failed"
    tail -50 /tmp/quality_gates_final.log
fi
```

**Success Criteria**:
- All quality gates pass
- Test coverage > 90%
- Zero clippy warnings
- Code formatting compliant

---

#### Step 17: Final Documentation

```bash
# Create merge completion report
cat > plans/phase2_merge_completion_report.md << 'EOF'

## Section 4: Risk Mitigation Strategies

### 4.1 Risk Assessment Matrix

| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| Build failure after tools.rs changes | Medium | High | Backup files, use git diff to verify changes, incremental testing |
| Import resolution errors | Low | Medium | Verify all imports exist before committing, use cargo check frequently |
| Test regressions | Low | High | Run test suite after each phase, compare with baseline |
| Function signature mismatch | Low | High | Compare signatures with PR #265 before changes |
| Batch module references | Medium | Medium | Explicitly skip batch routing, verify no compilation errors |

### 4.2 Mitigation Strategies

#### Strategy 1: Incremental Testing
**Description**: Test after each major change group
**Execution**:
```bash
# After each phase:
cargo check -p do-memory-cli  # For CLI changes
cargo check -p do-memory-mcp  # For server changes
cargo test -p do-memory-cli   # For CLI tests
cargo test -p do-memory-mcp   # For server tests
```

#### Strategy 2: File Backups
**Description**: Keep backups of all modified files
**Execution**:
```bash
# Before modifying any file:
cp <file> /tmp/$(basename <file>).backup.$(date +%s)

# To restore if needed:
cp /tmp/<file>.backup.* <file>
```

#### Strategy 3: Git Staging Strategy
**Description**: Stage changes incrementally
**Execution**:
```bash
# Stage only verified changes
git add <specific-files>

# Commit each phase separately
git commit -m "Phase X: Description"

# If issues, easy to revert
git reset --soft HEAD~1
```

#### Strategy 4: Diff Comparison
**Description**: Compare changes with PR #265 to ensure correctness
**Execution**:
```bash
# For critical files, show the diff we expect:
git diff pr-272 pr-265 -- do-memory-mcp/src/bin/server/tools.rs | grep -A 5 -B 5 "handle_validate"

# After our changes, verify they match:
git diff HEAD -- do-memory-mcp/src/bin/server_impl/tools.rs | grep -A 5 -B 5 "handle_validate"
```

---

## Section 5: Rollback Plan

### 5.1 Rollback Scenarios

#### Scenario A: Build Failure After Tools.rs Changes
```bash
# Immediate rollback
cp /tmp/tools_backup.rs do-memory-mcp/src/bin/server_impl/tools.rs
cargo check -p do-memory-mcp

# Or use git
git checkout HEAD -- do-memory-mcp/src/bin/server_impl/tools.rs
```

#### Scenario B: Build Failure After Handlers.rs Changes
```bash
# Immediate rollback
cp /tmp/handlers_backup.rs do-memory-mcp/src/bin/server_impl/handlers.rs
cargo check -p do-memory-mcp

# Or use git
git checkout HEAD -- do-memory-mcp/src/bin/server_impl/handlers.rs
```

#### Scenario C: Test Failures
```bash
# Identify which commit introduced failures
git log --oneline --all

# Revert specific phase
git revert <commit-hash>

# Or reset to last known good state
git reset --hard <last-good-commit>
```

#### Scenario D: Complete Rollback
```bash
# If everything goes wrong:
git checkout main
git branch -D integration/pr265-onto-pr272

# Start fresh
git checkout -b integration/pr265-onto-pr272 pr-272
```

### 5.2 Recovery Checkpoints

Create tagged checkpoints after each phase:

```bash
# After Phase 1 (Preparation)
git tag checkpoint/phase1-preparation

# After Phase 2 (Safe Changes)
git add -A && git commit -m "Phase 2: Apply safe CLI and core changes"
git tag checkpoint/phase2-safe-changes

# After Phase 3 (Critical Merge)
git add -A && git commit -m "Phase 3: Manual merge of server_impl files"
git tag checkpoint/phase3-critical-merge

# To rollback to checkpoint:
git reset --hard checkpoint/phase2-safe-changes
```
