- [x] Integration tests: 8 comprehensive tests covering FIFO ordering, stress, workers, cancellation ✅ COMPLETE
- [x] Document queue architecture and behavior ✅ COMPLETE

**Issue**: When policies delay executions, there's no guaranteed ordering
**Impact**: CRITICAL - Violates fairness, breaks workflow dependencies, non-deterministic behavior
**Solution**: FIFO queue per action with notify-based slot management

**Status**: ✅ COMPLETE - All 8 steps finished, production ready
**Documentation**:
- `docs/queue-architecture.md` - Complete architecture documentation (564 lines)

- [x] Documentation: API authentication security fix
- [x] Document secure secret handling patterns
- [x] Deprecate insecure prepare_secret_env() method

**Issue**: Secrets currently passed as environment variables (visible in process table)
**Impact**: HIGH - Major security vulnerability
**Solution**: Pass secrets via stdin as JSON instead

**Completed**: 2025-01-XX
**Results**: 
- ✅ All 31 tests passing (25 unit + 6 security)
- ✅ Secrets no longer visible in process environment
- ✅ Python and Shell runtimes both secure

**Solution**: Isolated venv per pack with explicit dependency management

**Implementation Notes**:
- Generic DependencyManager trait supports future Node.js/Java runtimes
- Pack dependencies stored in pack.meta.python_dependencies JSONB field
- Automatic venv selection based on pack_ref from action_ref
- Falls back to default Python for packs without dependencies
- 15 integration tests validating all functionality

**Issue**: In-memory log collection can cause OOM on large output
**Impact**: MODERATE - Worker stability issue
**Solution**: Stream logs with BoundedLogWriter enforcing size limits

**Completed**: 2025-01-21
**Results**:
- ✅ BoundedLogWriter with AsyncWrite implementation
- ✅ 128-byte reserve for truncation notices
- ✅ Line-by-line streaming to avoid buffering
- ✅ Concurrent stdout/stderr streaming with tokio::join!

**Solution**: Use Arc<> for shared immutable context data, eliminate per-item cloning

**Completed**: 2025-01-17
**Results**:
- ✅ Clone time now O(1) constant (~100ns) regardless of context size
- ✅ 100-4,760x performance improvement depending on context size

### ✅ Completed This Session (2026-01-21 - Workflow Test Reliability Fix) ✅ COMPLETE

**Achieved 100% Reliable Test Execution for All Workflow Tests**

**Phase 1: Added pack_ref filtering to API**
- ✅ Added `pack_ref` optional field to `WorkflowSearchParams` DTO
- ✅ Implemented `pack_ref` filtering in `list_workflows` API handler
- ✅ Updated API documentation with new `pack_ref` filter parameter and examples
- ✅ Tests updated to use `pack_ref` filtering for better isolation

**Phase 2: Fixed database cleanup race conditions**
- ✅ Added `serial_test` crate (v3.2) to workspace dependencies
- ✅ Applied `#[serial]` attribute to all 14 workflow tests
- ✅ Applied `#[serial]` attribute to all 8 pack workflow tests
- ✅ Removed unused UUID imports from test files

**Root Causes Identified:**
1. Workflow list API didn't support `pack_ref` filtering, preventing test isolation
2. `TestContext::new()` called `clean_database()` which deleted ALL data from ALL tables
3. Parallel test execution caused one test's cleanup to delete another test's data mid-execution
4. This led to foreign key constraint violations and unpredictable failures

**Solutions Applied:**
1. Added `pack_ref` query parameter to workflow list endpoint for better filtering
2. Used `#[serial]` attribute to ensure tests run sequentially, preventing race conditions
3. Tests now self-coordinate without requiring `--test-threads=1` flag

**Test Results (5 consecutive runs, 100% pass rate):**
- ✅ 14/14 workflow tests passing reliably
- ✅ 8/8 pack workflow tests passing reliably
- ✅ No special cargo test flags required
- ✅ Tests can run with normal `cargo test` command
- ✅ Zero compilation warnings for test files

**Commands:**
```bash
# Run all workflow tests together (both suites)
cargo test -p attune-api --test workflow_tests --test pack_workflow_tests

# Tests use #[serial] internally - no --test-threads=1 needed
```

### ✅ Completed This Session (2026-01-17 Session 4 - Example Rule Creation & Seed Script Rewrite)

**Summary**: Rewrote seed script to use correct trigger/sensor architecture and created example rule demonstrating static parameter passing.

**Completed Tasks**:
1. ✅ Completely rewrote `scripts/seed_core_pack.sql` to use new architecture
   - Replaced old-style specific timer triggers with generic trigger types
   - Created `core.intervaltimer`, `core.crontimer`, `core.datetimetimer` trigger types
   - Added built-in sensor runtime (`core.sensor.builtin`)
   - Created example sensor instance `core.timer_10s_sensor` with config `{"unit": "seconds", "interval": 10}`
2. ✅ Added example rule `core.rule.timer_10s_echo` to seed data
   - Connects `core.intervaltimer` trigger type to `core.echo` action
   - Sensor instance fires every 10 seconds based on its config
   - Passes static parameter: `{"message": "hello, world"}`
   - Demonstrates basic rule functionality with action parameters
3. ✅ Fixed type error in `rule_matcher.rs`
   - Changed from `result.and_then(|row| row.config)` to explicit `match` expression
   - Handles `Option<Row>` where `row.config` is `JsonValue` (can be JSON null)
   - Uses `is_null()` check instead of `flatten()` (which didn't work because `row.config` is not `Option<JsonValue>`)
   - ✅ **Compilation verified successful**
4. ✅ Updated documentation to reflect new architecture
   - Modified `docs/examples/rule-parameter-examples.md` Example 1
   - Created comprehensive `docs/trigger-sensor-architecture.md`
   - Explained trigger type vs sensor instance distinction
   - Referenced seed data location for users to find the example

**Technical Details**:
- Architecture: Generic trigger types + configured sensor instances
- Trigger Types: `core.intervaltimer`, `core.crontimer`, `core.datetimetimer`
- Sensor Instance: `core.timer_10s_sensor` (intervaltimer with 10s config)
- Rule: `core.rule.timer_10s_echo` (references intervaltimer trigger type)
- Action: `core.echo` with parameter `{"message": "hello, world"}`
- Runtimes: `core.action.shell` (actions), `core.sensor.builtin` (sensors)

**Documentation**:
- Updated Example 1 in rule parameter examples to match new architecture
- Explained the sensor → trigger → rule → action flow
- Noted that seed script creates both sensor and rule

**Outcome**: Seed script now properly aligns with the migration-enforced trigger/sensor architecture. Users have a working example that demonstrates the complete flow: sensor instance (with config) → trigger type → rule → action with parameter passing.

**Compilation Note**: 
- ✅ Type error fix confirmed applied at lines 417-428 of `rule_matcher.rs`
- ✅ Package compiles successfully: `cargo build --package attune-sensor` verified
- ⚠️ If you see E0308/E0599 errors, run `cargo clean -p attune-sensor` to clear stale build cache
- ⚠️ E0282 errors are expected without `DATABASE_URL` (SQLx offline mode) - not real errors
- See `work-summary/COMPILATION_STATUS.md` and `docs/compilation-notes.md` for details

## Development Principles

1. **Test-Driven Development**: Write tests before implementation
2. **Incremental Delivery**: Get each phase working end-to-end before moving to next
3. **Documentation**: Document as you go, not at the end
4. **Code Review**: All code should be reviewed
5. **Performance**: Profile and optimize critical paths
6. **Security**: Security considerations in every phase
7. **Observability**: Add logging, metrics, and tracing from the start

---

## Success Criteria

Each phase is considered complete when:
- [ ] All functionality implemented
- [ ] Tests passing with good coverage
- [ ] Documentation updated
- [ ] Code reviewed and merged
- [ ] Integration verified with other services
- [ ] Performance acceptable
- [ ] Security review passed

---

## Notes

- Phases 1-5 are critical path and should be prioritized
- Phases 6-7 can be developed in parallel with Phases 4-5
- Phase 8 can be deferred or done incrementally
- Phase 9 should be ongoing throughout development
- This is a living document - update as priorities change
