## Phase 3: Integration Test Design ✅

### Test 1: Create → Save → Recall Workflow

**Purpose:** Validate the complete end-to-end flow of the context recall system.

**Steps:**
1. Create conversation context using `compress_conversation_summary()`
2. Save compressed context to database via POST `/api/conversation-contexts`
3. Recall context via GET `/api/conversation-contexts/recall?project_id={id}`
4. Verify `format_for_injection()` output is ready for Claude prompt

**Validation:**
- Context saved successfully with compressed JSON
- Recall endpoint returns formatted markdown string
- Token count is optimized for Claude prompt injection
- All critical information preserved through compression

### Test 2: Cross-Machine Context Sharing

**Purpose:** Test context recall across different machines working on the same project.

**Steps:**
1. Create contexts from Machine 1 with `machine_id=machine1_id`
2. Create contexts from Machine 2 with `machine_id=machine2_id`
3. Query by `project_id` (no machine filter)
4. Verify contexts from both machines are returned and merged

**Validation:**
- Machine-agnostic project context retrieval
- Contexts from different machines properly merged
- Session/machine metadata preserved for audit trail

---

## Phase 4: Hook Simulation Test Design ✅

### Hook 1: user-prompt-submit

**Scenario:** Claude user submits a prompt, hook queries context for injection.

**Steps:**
1. Simulate hook triggering on prompt submit
2. Query `/api/conversation-contexts/recall?project_id={id}&limit=10&min_relevance_score=5.0`
3. Measure query performance
4. Verify response format matches Claude prompt injection requirements

**Success Criteria:**
- Response time < 1 second
- Returns formatted context string
- Context includes project-relevant snippets and decisions
- Token-efficient for prompt budget

### Hook 2: task-complete

**Scenario:** Claude completes a task, hook saves context to database.

**Steps:**
1. Simulate task completion
2. Compress conversation using `compress_conversation_summary()`
3. POST compressed context to `/api/conversation-contexts`
4. Measure save performance
5. Verify context saved with correct metadata

**Success Criteria:**
- Save time < 1 second
- Context properly compressed before storage
- Relevance score calculated correctly
- Tags and decisions extracted automatically

---

## Phase 5: Project State Test Design ✅

### Test 1: Project State Upsert Workflow

**Purpose:** Validate upsert functionality ensures one state per project.

**Steps:**
1. Create initial project state with 25% progress
2. Update project state to 50% progress using upsert endpoint
3. Verify same record updated (ID unchanged)
4. Update again to 75% progress
5. Confirm no duplicate states created

**Validation:**
- Upsert creates state if missing
- Upsert updates existing state (no duplicates)
- `updated_at` timestamp changes
- Previous values overwritten correctly

### Test 2: Next Actions Tracking

**Purpose:** Test dynamic next actions list updates.

**Steps:**
1. Set initial next actions: `["complete tests", "deploy"]`
2. Update to new actions: `["create report", "document findings"]`
3. Verify list completely replaced (not appended)
4. Verify JSON structure maintained

---

## Phase 6: Usage Tracking Test Design ✅

### Test 1: Snippet Usage Tracking

**Purpose:** Verify usage count increments on retrieval.

**Steps:**
1. Create snippet with `usage_count=0`
2. Retrieve snippet 5 times via GET `/api/context-snippets/{id}`
3. Retrieve final time and check count
4. Expected: `usage_count=6` (5 + 1 final)

**Validation:**
- Every GET increments counter
- Counter persists across requests
- Used for relevance score calculation

### Test 2: Relevance Score Calculation

**Purpose:** Validate relevance score weights usage appropriately.

**Test Data:**
- Snippet A: `usage_count=2`, `importance=5`
- Snippet B: `usage_count=20`, `importance=5`

**Expected:**
- Snippet B has higher relevance score
- Usage boost (+0.2 per use, max +2.0) increases score
- Age decay reduces score over time
- Important tags boost score

**Test:** Query recall endpoint 10 times, measure response times.

**Metrics:**
- Average response time
- Min/Max response times
- Token count in response
- Number of contexts returned

**Target:** Average < 500ms

### Benchmark 2: Bulk Context Creation

**Test:** Create 20 contexts sequentially, measure performance.

**Metrics:**
- Total time for 20 contexts
- Average time per context
- Database connection pooling efficiency

**Target:** Average < 300ms per context
