Unreleased

Removed - 2026-01-27 (Workflow Task Execution Cleanup)

Deprecated Code Removal: WorkflowTaskExecution Consolidation Complete

Following the consolidation of workflow_task_execution table into execution.workflow_task JSONB column, all deprecated code has been removed:

• ❌ Removed WorkflowTaskExecutionRepository struct and all implementations
• ❌ Removed CreateWorkflowTaskExecutionInput type
• ❌ Removed UpdateWorkflowTaskExecutionInput type
• ❌ Removed WorkflowTaskExecution type alias
• ❌ Removed deprecated exports from repositories/mod.rs and workflow/mod.rs
• ✅ Updated test helpers to remove references to old table
• ✅ Updated comments in registrar files to reflect new model

Breaking Change: Code must now use ExecutionRepository with the workflow_task JSONB field. See docs/migrations/workflow-task-execution-consolidation.md for migration guide.

Rationale: As a pre-production project with no users or deployments, we removed all deprecated code immediately rather than maintaining it through a deprecation period. This keeps the codebase clean and prevents accumulation of technical debt.

• crates/api/src/dto/trigger.rs - Added missing config field to test fixture
• crates/sensor/src/event_generator.rs - Fixed Trigger test fixture to use webhook_config instead of deprecated individual webhook fields
• .rules - Updated to note cleanup completion

Files Deleted:

• CONSOLIDATION_SUMMARY.md - Work complete, no longer needed

• PARENT_FIELD_ANALYSIS.md - Work complete, no longer needed
• docs/examples/workflow-migration.sql - Showed old schema, use git history if needed
• docs/workflow-models-api.md - Documented old API, use git history if needed

Documentation Updated:

• docs/migrations/workflow-task-execution-consolidation.md - Updated to note deprecated code removed

Result:

• ✅ Zero deprecation warnings
• ✅ Cleaner codebase with no legacy code paths
• ✅ All code uses unified ExecutionRepository API
• ✅ Compilation successful across all workspace crates
• ✅ All test files updated with workflow_task field
• ✅ Repository SQL queries properly handle JSONB workflow_task column

Fixed - 2026-01-29 (E2E Test Infrastructure Updates)

Issue Resolved: Service Management and API Client Compatibility

• ✅ Fixed restart_sensor_service() to work with E2E services managed by start-e2e-services.sh
• ✅ Removed systemd/systemctl dependencies from E2E tests
• ✅ Updated client wrapper to use PID files for service restart
• ✅ Fixed API client wrapper compatibility with ref-based endpoints
• ✅ Created database migration to fix webhook function overload issue

Service Management Changes:

• Updated restart_sensor_service() in tests/helpers/fixtures.py
• Now reads/writes PID files from tests/pids/ directory
• Uses SIGTERM for graceful shutdown, SIGKILL if needed
• Restarts service using ./target/debug/attune-sensor with E2E config
• Properly handles process lifecycle without systemd

API Client Wrapper Fixes:

• Updated create_action() to use plain POST request (handles pack_ref, runtime_ref instead of pack_id, runtime)
• Updated create_trigger() to use plain POST request (handles pack_ref instead of pack_id)
• Updated create_rule() to use plain POST request (handles pack_ref, trigger_ref instead of pack_id, trigger_id)
• Added enable_webhook() and disable_webhook() methods
• Updated fire_webhook() to auto-enable webhooks and use plain POST request
• All methods now support both new-style (ref-based) and legacy-style (id/name-based) arguments for backward compatibility

Database Migration:

• Created 20260129000001_fix_webhook_function_overload.sql
• Drops old enable_trigger_webhook(BIGINT) function signature
• Resolves "function is not unique" error when enabling webhooks
• Ensures only the newer version with JSONB config parameter exists

Files Modified:

• ✅ Service management works with development environment setup
• ✅ All 6 basic E2E tests passing (test_e2e_basic.py)
• ✅ Webhook enablement works correctly (200 OK responses)
• ✅ Client wrapper fully adapted to ref-based API structure

Changed - 2025-01-27 (API Endpoint Standardization)

Breaking Change: Removed ID-based endpoints for deployable components

• ✅ Removed /id/{id} endpoints for actions, triggers, sensors, rules, workflows, and packs
• ✅ All deployable components now exclusively use reference-based access (/{ref})
• ✅ Transient resources (executions, events, enforcements, inquiries) continue using ID-based access
• ✅ Updated OpenAPI specification (57 paths, 81 operations)
• ✅ Updated API documentation for all affected endpoints

Removed Endpoints:

• GET /api/v1/actions/id/{id} → Use GET /api/v1/actions/{ref}
• GET /api/v1/triggers/id/{id} → Use GET /api/v1/triggers/{ref}
• GET /api/v1/sensors/id/{id} → Use GET /api/v1/sensors/{ref}
• GET /api/v1/rules/id/{id} → Use GET /api/v1/rules/{ref}
• GET /api/v1/workflows/id/{id} → Use GET /api/v1/workflows/{ref}
• GET /api/v1/packs/id/{id} → Use GET /api/v1/packs/{ref}

Benefits:

• Consistent, ref-only access pattern for all deployable components
• Better portability across environments (refs are environment-agnostic)
• Clearer architectural distinction between deployable and transient resources
• More meaningful identifiers (e.g., core.http.get vs numeric ID)

Migration: No impact as project has no production users yet. Future API consumers should use reference-based endpoints exclusively for deployable components.

Architectural Notes

Pack-Based vs UI-Configurable Components:

• Actions and Sensors: Code-based components registered via pack installation (NOT editable in UI)
  • Implemented as executable code (Python, Node.js, Shell)
  • Managed through pack lifecycle (install, update, uninstall)
  • Ensures security, performance, and maintainability
• Triggers: Mixed model
  • Pack-based triggers: Registered with system packs (e.g., slack.message_received)
  • Ad-hoc triggers: UI-configurable for custom integrations (future feature)
• Rules: Always UI-configurable
  • Connect triggers to actions with criteria and parameters
  • No code execution, just data mapping
• Packs: Two types
  • System packs: Installed via pack management tools, contain code
  • Ad-hoc packs: Registered via UI for custom event types and configuration

  • Removed topological sort, level computation, and cycle detection
  • Coordinator uses event-driven scheduling based on task completions
  • Added join field support for barrier synchronization in parallel workflows

• New Capabilities:

  • Monitoring loops that retry on failure
  • Iterative workflows with conditional exit

    • core.intervaltimer - Fires at regular intervals (configurable unit and interval)
    • core.crontimer - Fires based on cron schedule expressions
    • core.datetimetimer - Fires once at a specific datetime
  • Added built-in sensor runtime (core.sensor.builtin) for system sensors
  • Created example sensor instance: core.timer_10s_sensor with config {"unit": "seconds", "interval": 10}
• New example rule: core.rule.timer_10s_echo
  • Connects core.intervaltimer trigger type to core.echo action
  • Sensor instance fires the trigger every 10 seconds

Added - 2026-01-16 (Execution Result Capture) ✅ COMPLETE

Comprehensive Execution Result Storage

• Implemented detailed execution result capture in worker service
  • Exit codes now recorded for all executions (0 = success)
  • stdout/stderr output captured and stored with 1000-char preview in database
  • Full log files saved to /tmp/attune/artifacts/execution_{id}/ directory
  • Log file paths stored in execution result for easy access
  • Execution duration tracked in milliseconds
  • Success flag (succeeded: true/false) for quick status checks

Shell Action Improvements

• Fixed shell action execution - entrypoint code now actually executes
  • Shell actions use entrypoint as executable code
  • Parameters exported both with and without PARAM_ prefix
  • Allows natural bash syntax: $message and $PARAM_MESSAGE both work

Parameter Handling Enhancement

• Improved parameter extraction from execution config
  • Handles parameters at config root level (from rule action_params)
  • Also supports nested config.parameters structure
  • Skips reserved keys like context and env

Result Format

{
  "exit_code": 0,
  "succeeded": true,
  "duration_ms": 2,
  "stdout": "hello, world\n",
  "stdout_log": "/tmp/attune/artifacts/execution_362/stdout.log"
}

Files Modified

• crates/worker/src/executor.rs - Enhanced result building, parameter extraction
• crates/worker/src/runtime/shell.rs - Dual parameter export (with/without prefix)
• crates/worker/src/artifacts.rs - Made get_execution_dir() public

Fixed - 2026-01-16 (Critical Pipeline Fixes) ✅ COMPLETE

Message Loop in Execution Manager

• Fixed infinite message loop where ExecutionCompleted messages were routed back to execution manager
  • Changed queue binding from wildcard execution.status.# to exact match execution.status.changed
  • Prevents completion messages from being reprocessed indefinitely
  • Execution manager now processes each status change exactly once

Worker Runtime Resolution

• Fixed runtime resolution failure where worker couldn't find correct runtime for actions
  • Added runtime_name field to ExecutionContext for explicit runtime specification
  • Updated worker to load runtime metadata from database (e.g., runtime: 3 → "shell")
  • Modified RuntimeRegistry::get_runtime() to prefer runtime_name over pattern matching
  • Registered individual Python and Shell runtimes alongside Local runtime
  • Runtime selection now based on authoritative database metadata, not file extension heuristics

End-to-End Pipeline Success

• Timer-driven automation pipeline now works end-to-end
  • Timer → Event → Rule Match → Enforcement → Execution → Worker (shell/python) → Completion
  • Actions execute successfully with correct runtime in ~2-3ms
  • Example: core.echo action executes with shell runtime as specified in database

Files Modified

• crates/common/src/mq/connection.rs - Queue binding fix
• crates/worker/src/runtime/mod.rs - Added runtime_name field, updated get_runtime()
• crates/worker/src/executor.rs - Load runtime from database
• crates/worker/src/service.rs - Register individual runtimes
• Test files updated for new runtime_name field

Changed - 2026-01-16 (Trigger Architecture Restructure) ✅ COMPLETE

Trigger and Sensor Architecture

• Restructured triggers to be generic event type definitions instead of hardcoded configurations
  • Created 3 generic timer triggers: core.intervaltimer, core.crontimer, core.datetimetimer
  • Triggers now have proper param_schema fields defining expected configuration structure
  • Removed old hardcoded triggers: core.timer_10s, core.timer_1m, core.timer_hourly
• Added config field to sensors for storing actual instance configuration values
  • Sensors now hold specific configurations that conform to trigger param schemas
  • Example: Sensor with {"unit": "seconds", "interval": 10} uses core.intervaltimer trigger
• Created sensor instances from old triggers - Data migration automatically converted:
  • core.timer_10s_sensor → uses core.intervaltimer with 10-second interval config
  • core.timer_1m_sensor → uses core.intervaltimer with 1-minute interval config
  • core.timer_hourly_sensor → uses core.crontimer with hourly cron expression
• Architecture benefits: Single trigger type for all interval timers, proper separation of trigger definitions from instance configurations, easier to create new timer instances dynamically

Fixed - 2026-01-16 (Enforcement Message Routing) ✅ COMPLETE

Enforcement to Execution Pipeline

• Fixed executions not being created despite events and enforcements working
  • Changed EnforcementCreated message to use attune.executions exchange instead of attune.events
  • Messages now properly route from sensor (rule matcher) to executor (enforcement processor)
  • Executor can now receive enforcement messages and create executions
• Message routing clarification - Organized exchanges by lifecycle domain
  • attune.events - Event generation and monitoring (EventCreated)
  • attune.executions - Execution lifecycle (EnforcementCreated, ExecutionRequested, etc.)
  • attune.notifications - Notification delivery (NotificationCreated)
• Complete execution pipeline now functional end-to-end
  • Timer triggers → Events → Rule matching → Enforcements → Executions → Worker execution

Fixed - 2026-01-16 (Message Queue Infrastructure) ✅ COMPLETE

Executions Exchange Type

• Changed attune.executions exchange from Direct to Topic for flexible routing
  • Direct exchange required exact routing key matches
  • Topic exchange supports wildcard patterns with # routing key
  • Now routes all execution-related messages: enforcement.created, execution.requested, etc.
• Updated queue bindings to use # wildcard for all execution messages
• Fixed EnforcementCreated routing - Messages now properly reach executor service

Fixed - 2026-01-16 (Worker Service Message Queue) ✅ COMPLETE

Worker Service Queue Setup

• Fixed "NOT_FOUND - no queue 'worker.1.executions'" error on worker service startup
  • Added automatic RabbitMQ infrastructure setup (exchanges, queues, bindings)
  • Worker-specific queues are created dynamically after worker registration
  • Queue name format: worker.{worker_id}.executions
• Dynamic queue management - Worker queues are ephemeral and auto-delete
  • Non-durable queues tied to worker lifetime
  • Auto-delete when worker disconnects (prevents orphaned queues)
  • Bound to attune.executions exchange with routing key worker.{worker_id}
• Targeted execution routing - Scheduler can route executions to specific workers
  • Each worker has its own queue for targeted message delivery
  • Enables worker-specific capabilities and load balancing

Fixed - 2026-01-15 (Message Queue Infrastructure) ✅ COMPLETE

Executor Service Queue Setup

• Fixed "NOT_FOUND - no queue 'executor.main'" error on executor service startup
  • Added automatic RabbitMQ infrastructure setup (exchanges, queues, bindings)
  • Changed executor to use configured queue name (attune.executions.queue) instead of hardcoded "executor.main"
  • Infrastructure setup is idempotent - safe to run multiple times
• Fixed "NOT_ALLOWED - attempt to reuse consumer tag" error
  • Each executor component now creates its own consumer with unique tag
  • Consumer tags: executor.enforcement, executor.scheduler, executor.manager
  • Implements competing consumers pattern for parallel message processing
• Automated queue creation - Services now create required infrastructure on startup
  • Creates exchanges: attune.events, attune.executions, attune.notifications
  • Creates queues with dead letter exchange support
  • Sets up proper routing bindings
• Production ready - Dead letter queues handle message failures with 24-hour TTL

Fixed - 2026-01-15 (Configuration URL Parsing) ✅ COMPLETE

Configuration System Fix

• Fixed configuration loading error where database and message queue URLs were incorrectly parsed as sequences
  • Removed .list_separator(",") from environment variable configuration to prevent URL parsing issues
  • Implemented custom string_or_vec deserializer for flexible array field handling
  • cors_origins now accepts both YAML array format and comma-separated environment variable strings
• Enhanced compatibility - All URL fields (database, message queue, redis) now parse correctly from environment variables
• Backward compatible - Existing YAML configurations continue to work without changes

Added - 2024-01-02 (StackStorm Pitfall Analysis) UPDATED

Security & Architecture Analysis

• Comprehensive StackStorm Pitfall Analysis - Identified critical security and architectural issues
  • Analyzed 7 potential pitfalls from StackStorm lessons learned (added P7 via user feedback)
  • Identified 3 critical security/correctness vulnerabilities requiring immediate attention
  • Documented 2 moderate issues for v1.0 release
  • Confirmed 2 pitfalls successfully avoided by Rust implementation

Critical Issues Discovered

• P7: Policy Execution Ordering (🔴 CRITICAL - P0 BLOCKING) NEW

  • Multiple delayed executions (due to concurrency limits) don't maintain request order
  • No FIFO queue for delayed executions - order is non-deterministic
  • Violates fairness expectations and can break workflow dependencies
  • Race conditions when policy slots become available
  • Solution: Implement ExecutionQueueManager with per-action FIFO queues

• P5: Insecure Secret Passing (🔴 CRITICAL - P0 BLOCKING)

  • Secrets currently passed as environment variables (visible in process table)
  • Vulnerable to inspection via ps auxwwe and /proc/{pid}/environ
  • Major security vulnerability requiring immediate fix before production
  • Solution: Pass secrets via stdin as JSON instead of environment variables

• P4: Dependency Hell & System Coupling (🔴 CRITICAL - P1)

  • All packs share system Python runtime
  • Upgrading system Python can break existing user actions
  • No dependency isolation between packs
  • Solution: Implement per-pack virtual environments with isolated dependencies

Moderate Issues Identified

• P6: Log Size Limits (⚠️ MODERATE - P1)

  • In-memory log buffering can cause worker OOM on large output
  • No size limits enforced on stdout/stderr
  • Solution: Streaming log collection with configurable size limits

• P3: Limited Language Ecosystem Support (⚠️ MODERATE - P2)

  • Pack runtime_deps field defined but not used
  • No pack installation service or dependency management
  • Solution: Implement PackInstaller with pip/npm integration

Issues Successfully Avoided

• P1: Action Coupling (✅ AVOIDED) - Actions execute as standalone processes, no Attune dependencies required
• P2: Type Safety (✅ AVOIDED) - Rust's strong type system eliminates runtime type issues

Documentation Created

• work-summary/StackStorm-Pitfalls-Analysis.md (659 lines) - Comprehensive analysis with testing checklist
• work-summary/Pitfall-Resolution-Plan.md (1,153 lines) - Detailed implementation plan with code examples
• work-summary/session-2024-01-02-stackstorm-analysis.md (449 lines) - Session summary and findings
• Updated work-summary/TODO.md with new Phase 0: StackStorm Pitfall Remediation (CRITICAL priority)

Architecture Decision Records

• ADR-001: Use Stdin for Secret Injection - Pass secrets via stdin instead of environment variables
• ADR-002: Per-Pack Virtual Environments - Isolate dependencies with pack-specific venvs
• ADR-003: Filesystem-Based Log Storage - Store logs in filesystem, not database (already implemented)

Remediation Plan

• Phase 1A: Correctness Critical (4-6 days) - Implement FIFO queue for policy-delayed executions
• Phase 1B: Security Critical (3-5 days) - Fix secret passing vulnerability via stdin injection
• Phase 2: Dependency Isolation (7-10 days) - Implement per-pack virtual environments
• Phase 3: Language Support (5-7 days) - Add multi-language dependency management
• Phase 4: Log Limits (3-4 days) - Implement streaming logs with size limits
• Total Estimated Effort: 22-32 days (4.5-6.5 weeks) - Updated from 18-26 days

Testing Requirements

• Correctness Tests (P7):

  • Verify three executions with limit=1 execute in FIFO order
  • Verify queue maintains order with 1000 concurrent enqueues
  • Verify worker completion notification releases queue slot
  • Verify queue stats API returns accurate counts

• Security Tests (P5):

  • Verify secrets not visible in process table (ps auxwwe)
  • Verify secrets not readable from /proc/{pid}/environ
  • Verify actions can successfully access secrets from stdin

• Isolation Tests (P4):

  • Test per-pack venv isolation

• Stability Tests (P6):

  • Test worker stability with large log output

Impact

• BLOCKING: Production deployment blocked until P7 (execution ordering) and P5 (secret security) fixed
• Required for v1.0: All critical and high priority issues must be resolved
• Timeline Adjustment: +4.5-6.5 weeks added to v1.0 release schedule for remediation
• User Contribution: P7 identified through user feedback during analysis session
