## Technical Implementation Highlights

### 1. Rule Criteria Filtering

**Jinja2 Expression Engine:**
```python
# Equality
criteria: "{{ trigger.payload.level == 'info' }}"

# Numeric comparison
criteria: "{{ trigger.payload.priority >= 7 }}"

# Complex boolean logic
criteria: "{{ (trigger.payload.level == 'error' and trigger.payload.priority > 5) 
           or trigger.payload.environment == 'production' }}"

# List membership
criteria: "{{ trigger.payload.status in ['critical', 'urgent', 'high'] }}"
```

**Test Design:**
- Tests all common operators (==, !=, >, <, >=, <=)
- Tests boolean logic (AND, OR, NOT)
- Tests list membership (in operator)
- Validates only matching rules fire
- Confirms non-matching events filtered out

---

### 2. Timer Cancellation

**State Transitions:**
```
enabled → disabled: executions stop
disabled → enabled: executions resume
enabled → deleted: executions stop permanently
```

**Test Design:**
- Create timer with rule enabled
- Wait for executions to confirm timer working
- Disable rule, verify no new executions
- Re-enable rule, verify executions resume
- Delete rule, verify permanent stop
- Allow tolerance for in-flight executions (±1)

---

### 3. Concurrent Timers

**Test Scenarios:**
- 3 timers with different intervals (3s, 5s, 7s)
- 5 identical timers (stress test)
- Precision validation under concurrent load

**Validation Approach:**
```python
# Expected execution count formula
expected = test_duration / interval

# Example: 21 seconds / 3 second interval = 7 executions
# Allow ±1 tolerance for timing variations

assert expected - 1 <= actual <= expected + 1
```

**Key Metrics:**
- Execution count accuracy: ±1 execution
- Timing precision: max delta ≤ 1 under load
- No interference between timers
- No timer drift over time

---

### 4. Multi-Tenant Pack Isolation

**Security Model:**
```
System Packs:
  - tenant_id = NULL
  - system = true
  - Visible to ALL tenants
  - Executable by ALL users
  - Cannot be deleted by regular users

User Packs:
  - tenant_id = <specific tenant>
  - Visible ONLY to owning tenant
  - Full CRUD access by owner
  - Returns 404/403 for cross-tenant access
```

**Test Design:**
- User 1 creates pack, User 2 cannot see it
- User 2 tries direct access → 404/403
- Both users see system packs (core)
- Both users can execute system pack actions
- No overlap in custom pack listings
