work-summary/2025-01-fifo-integration-tests.md - Test execution guide (359 lines)
crates/executor/tests/README.md - Test suite quick reference

0.2 Security Critical - API Authentication & Secret Passing (P0 - BLOCKING) ✅ COMPLETE

Estimated Time: 3-5 days | Actual Time: 5 hours

Secret Passing Fix:

Update ExecutionContext to include secrets field separate from env
Remove secrets from environment variables in SecretManager
Implement stdin-based secret injection in Python runtime
Implement stdin-based secret injection in Shell runtime
Update Python wrapper script to read secrets from stdin
Update Shell wrapper script to read secrets from stdin

Secure workflow, trigger, inquiry, event, and key routes
Keep public routes accessible (health, login, register)
Verify all tests pass (46/46)
Documentation: API authentication security fix
Document secure secret handling patterns
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
✅ Zero breaking changes
✅ get_secret() helper functions provided
📄 See: work-summary/2025-01-secret-passing-complete.md

TODO: Create user-facing migration guide

0.3 Dependency Isolation (P1 - HIGH) ✅ COMPLETE

Estimated Time: 7-10 days | Actual Time: 2 days

Test: Environment validation and cleanup
Documentation: Complete guide in docs/dependency-isolation.md

Issue: Shared system Python runtime creates dependency conflicts Impact: CRITICAL - Can break existing actions on system upgrades 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

0.4 Language Ecosystem Support (P2 - MEDIUM)

Estimated Time: 5-7 days

Implement Node.js runtime with npm support
Enhance runtime detection (use action.runtime field)
Create pack upload/extraction API endpoint
Add pack installation status tracking
Support requirements.txt for Python packs
Support package.json for Node.js packs
Document pack metadata format
Test: Python pack with dependencies
Test: Node.js pack with dependencies

Issue: Limited support for language-specific dependency management Impact: MODERATE - Limits pack ecosystem growth Solution: Standardized dependency declaration per language

0.5 Log Size Limits (P1 - HIGH) ✅ COMPLETE

Estimated Time: 3-4 days | Actual Time: 1 day

Document log limits and best practices
Implement log pagination API endpoint (DEFERRED - not critical for MVP)
Add log rotation for large executions (DEFERRED - truncation is sufficient)

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!

✅ All 43 worker tests passing
📄 See: docs/log-size-limits.md (346 lines)

0.6 Workflow List Iteration Performance (P0 - BLOCKING) ✅ COMPLETE

Estimated Time: 5-7 days | Actual Time: 3 hours

Implement Arc-based WorkflowContext to eliminate O(N*C) cloning
Refactor context to use Arc for shared immutable data
Update execute_with_items to use shared context references
Create performance benchmarks for context cloning
Create benchmark for with-items scaling (10-10000 items)
Test: 1000-item list with 100 prior task results completes efficiently
Test: Memory usage stays constant across list iterations
Document Arc-based context architecture

Issue: Context cloning in with-items creates O(N*C) complexity where N=items, C=context size Impact: CRITICAL - Can cause exponential performance degradation and OOM with large lists 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
✅ Memory usage reduced 1,000-25,000x for large lists
✅ All 55 executor tests passing

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

Solutions Applied:

Added pack_ref query parameter to workflow list endpoint for better filtering
Used #[serial] attribute to ensure tests run sequentially, preventing race conditions
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:

# 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:

✅ 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}
✅ 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
✅ 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
✅ 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

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
