+### Runtime Environments Volume
+- **Key Principle**: Runtime environments (virtualenvs, node_modules) are stored OUTSIDE pack directories
+- **Volume**: `runtime_envs` named volume mounted at `/opt/attune/runtime_envs` in worker and API containers
+- **Path Pattern**: `{runtime_envs_dir}/{pack_ref}/{runtime_name}` (e.g., `/opt/attune/runtime_envs/python_example/python`)
+- **Creation**: Worker creates environments on-demand before first action execution (idempotent)
+- **API best-effort**: API attempts environment setup during pack registration but logs and defers to worker on failure (Docker API containers lack interpreters)
+- **Pack directories remain read-only**: Packs mounted `:ro` in workers; all generated env files go to `runtime_envs` volume
+- **Config**: `runtime_envs_dir` setting in config YAML (default: `/opt/attune/runtime_envs`)

 - **JSON Fields**: Use `serde_json::Value` for flexible attributes/parameters, including `execution.workflow_task` JSONB

 - **Workflow Tasks**: Stored as JSONB in `execution.workflow_task` (consolidated from separate table 2026-01-27)
+- **FK ON DELETE Policy**: Historical records (executions, events, enforcements) use `ON DELETE SET NULL` so they survive entity deletion while preserving text ref fields (`action_ref`, `trigger_ref`, etc.) for auditing. Pack-owned entities (actions, triggers, sensors, rules, runtimes) use `ON DELETE CASCADE` from pack. Workflow executions cascade-delete with their workflow definition.
+- **Nullable FK Fields**: `rule.action` and `rule.trigger` are nullable (`Option<Id>` in Rust) — a rule with NULL action/trigger is non-functional but preserved for traceability. `execution.action`, `execution.parent`, `execution.enforcement`, and `event.source` are also nullable.
 **Table Count**: 17 tables total in the schema
+- **Pack Component Loading Order**: Runtimes → Triggers → Actions → Sensors (dependency order). Both `PackComponentLoader` (Rust) and `load_core_pack.py` (Python) follow this order.

   - Development packs in `./packs.dev/` are bind-mounted directly for instant updates
 - **Pack Binaries**: Native binaries (sensors) built separately with `./scripts/build-pack-binaries.sh`
 - **Action Script Resolution**: Worker constructs file paths as `{packs_base_dir}/{pack_ref}/actions/{entrypoint}`
-- **Runtime Selection**: Determined by action's runtime field (e.g., "Shell", "Python") - compared case-insensitively
+- **Runtime YAML Loading**: Pack registration reads `runtimes/*.yaml` files and inserts them into the `runtime` table. Runtime refs use format `{pack_ref}.{name}` (e.g., `core.python`, `core.shell`).
+- **Runtime Selection**: Determined by action's runtime field (e.g., "Shell", "Python") - compared case-insensitively; when an explicit `runtime_name` is set in execution context, it is authoritative (no fallback to extension matching)
+- **Worker Runtime Loading**: Worker loads all runtimes from DB that have a non-empty `execution_config` (i.e., runtimes with an interpreter configured). Builtin runtimes (e.g., sensor runtime with empty config) are automatically skipped.
+- **Runtime Environment Setup**: Worker creates isolated environments (virtualenvs, node_modules) on-demand at `{runtime_envs_dir}/{pack_ref}/{runtime_name}` before first execution; setup is idempotent
 - **Parameter Delivery**: Actions receive parameters via stdin as JSON (never environment variables)
 - **Output Format**: Actions declare output format (text/json/yaml) - json/yaml are parsed into execution.result JSONB
 - **Standard Environment Variables**: Worker provides execution context via `ATTUNE_*` environment variables:

-USAGE EXAMPLE:
-
-To verify Python runtime availability:
-1. Query: SELECT distributions->'verification'->'commands' FROM runtime WHERE ref = 'core.sensor.python'
-2. Parse commands array
-3. Try each command in priority order
-4. If any command succeeds with expected exit_code and matches pattern (if provided), runtime is available
-5. If all commands fail, runtime is not available
-
-For always_available runtimes (shell, native):
-1. Check distributions->'verification'->'always_available'
-2. If true, skip verification and report as available

--- Migration: Unify Runtimes (Remove runtime_type distinction)
--- Description: Removes the runtime_type field and consolidates sensor/action runtimes

---              same binaries and verification logic, so the distinction is redundant.

-# Attune Database Migrations
-
-This directory contains SQL migrations for the Attune automation platform database schema.
-
-## Overview
-
-Migrations are numbered and executed in order. Each migration file is named with a timestamp prefix to ensure proper ordering:
-
-```
-YYYYMMDDHHMMSS_description.sql
-```
-
-## Migration Files
-
-The schema is organized into 5 logical migration files:
-
-| File | Description |
-|------|-------------|
-| `20250101000001_initial_setup.sql` | Creates schema, service role, all enum types, and shared functions |
-| `20250101000002_core_tables.sql` | Creates pack, runtime, worker, identity, permission_set, permission_assignment, policy, and key tables |
-| `20250101000003_event_system.sql` | Creates trigger, sensor, event, and enforcement tables |
-| `20250101000004_execution_system.sql` | Creates action, rule, execution, inquiry, workflow orchestration tables (workflow_definition, workflow_execution, workflow_task_execution), and workflow views |
-| `20250101000005_supporting_tables.sql` | Creates notification, artifact, and queue_stats tables with performance indexes |
-
-### Migration Dependencies
-
-The migrations must be run in order due to foreign key dependencies:
-
-1. **Initial Setup** - Foundation (schema, enums, functions)
-2. **Core Tables** - Base entities (pack, runtime, worker, identity, permissions, policy, key)
-3. **Event System** - Event monitoring (trigger, sensor, event, enforcement)
-4. **Execution System** - Action execution (action, rule, execution, inquiry)
-5. **Supporting Tables** - Auxiliary features (notification, artifact)
-
-## Running Migrations
-
-### Using SQLx CLI
-
-```bash
-# Install sqlx-cli if not already installed
-cargo install sqlx-cli --no-default-features --features postgres
-
-# Run all pending migrations
-sqlx migrate run
-
-# Check migration status
-sqlx migrate info
-
-# Revert last migration (if needed)
-sqlx migrate revert
-```
-
-### Manual Execution
-
-You can also run migrations manually using `psql`:
-
-```bash
-# Run all migrations in order
-for file in migrations/202501*.sql; do
-    psql -U postgres -d attune -f "$file"
-done
-```
-
-Or individually:
-
-```bash
-psql -U postgres -d attune -f migrations/20250101000001_initial_setup.sql
-psql -U postgres -d attune -f migrations/20250101000002_core_tables.sql
-# ... etc
-```
-
-## Database Setup
-
-### Prerequisites
-
-1. PostgreSQL 14 or later installed
-2. Create the database:
-
-```bash
-createdb attune
-```
-
-3. Set environment variable:
-
-```bash
-export DATABASE_URL="postgresql://postgres:postgres@localhost:5432/attune"
-```
-
-### Initial Setup
-
-```bash
-# Navigate to workspace root
-cd /path/to/attune
-
-# Run migrations
-sqlx migrate run
-
-# Verify tables were created
-psql -U postgres -d attune -c "\dt attune.*"
-```
-
-## Schema Overview
-
-The Attune schema includes 22 tables organized into logical groups:
-
-### Core Tables (Migration 2)
-- **pack**: Automation component bundles
-- **runtime**: Execution environments (Python, Node.js, containers)
-- **worker**: Execution workers
-- **identity**: Users and service accounts
-- **permission_set**: Permission groups (like roles)
-- **permission_assignment**: Identity-permission links (many-to-many)
-- **policy**: Execution policies (rate limiting, concurrency)
-- **key**: Secure configuration and secrets storage
-
-### Event System (Migration 3)
-- **trigger**: Event type definitions
-- **sensor**: Event monitors that watch for triggers
-- **event**: Event instances (trigger firings)
-- **enforcement**: Rule activation instances
-
-### Execution System (Migration 4)
-- **action**: Executable operations (can be workflows)
-- **rule**: Trigger-to-action automation logic
-- **execution**: Action execution instances (supports workflows)
-- **inquiry**: Human-in-the-loop interactions (approvals, inputs)
-- **workflow_definition**: YAML-based workflow definitions (composable action graphs)
-- **workflow_execution**: Runtime state tracking for workflow executions
-- **workflow_task_execution**: Individual task executions within workflows
-
-### Supporting Tables (Migration 5)
-- **notification**: Real-time system notifications (uses PostgreSQL LISTEN/NOTIFY)
-- **artifact**: Execution outputs (files, logs, progress data)
-- **queue_stats**: Real-time execution queue statistics for FIFO ordering
-
-## Key Features
-
-### Automatic Timestamps
-All tables include `created` and `updated` timestamps that are automatically managed by the `update_updated_column()` trigger function.
-
-### Reference Preservation
-Tables use both ID foreign keys and `*_ref` text columns. The ref columns preserve string references even when the referenced entity is deleted, maintaining complete audit trails.
-
-### Soft Deletes
-Foreign keys strategically use:
-- `ON DELETE CASCADE` - For dependent data that should be removed
-- `ON DELETE SET NULL` - To preserve historical records while breaking the link
-
-### Validation Constraints
-- **Reference format validation** - Lowercase, specific patterns (e.g., `pack.name`)
-- **Semantic version validation** - For pack versions
-- **Ownership validation** - Custom trigger for key table ownership rules
-- **Range checks** - Port numbers, positive thresholds, etc.
-
-### Performance Optimization
-- **B-tree indexes** - On frequently queried columns (IDs, refs, status, timestamps)
-- **Partial indexes** - For filtered queries (e.g., `enabled = TRUE`)
-- **GIN indexes** - On JSONB and array columns for fast containment queries
-- **Composite indexes** - For common multi-column query patterns
-
-### PostgreSQL Features
-- **JSONB** - Flexible schema storage for configurations, payloads, results
-- **Array types** - Multi-value fields (tags, parameters, dependencies)
-- **Custom enum types** - Constrained string values with type safety
-- **Triggers** - Data validation, timestamp management, notifications
-- **pg_notify** - Real-time notifications via PostgreSQL's LISTEN/NOTIFY
-
-## Service Role
-
-The migrations create a `svc_attune` role with appropriate permissions. **Change the password in production:**
-
-```sql
-ALTER ROLE svc_attune WITH PASSWORD 'secure_password_here';
-```
-
-The default password is `attune_service_password` (only for development).
-
-## Rollback Strategy
-
-### Complete Reset
-
-To completely reset the database:
-
-```bash
-# Drop and recreate
-dropdb attune
-createdb attune
-sqlx migrate run
-```
-
-Or drop just the schema:
-
-```sql
-psql -U postgres -d attune -c "DROP SCHEMA attune CASCADE;"
-```
-
-Then re-run migrations.
-
-### Individual Migration Revert
-
-With SQLx CLI:
-
-```bash
-sqlx migrate revert
-```
-
-Or manually remove from tracking:
-
-```sql
-DELETE FROM _sqlx_migrations WHERE version = 20250101000001;
-```
-
-## Best Practices
-
-1. **Never edit existing migrations** - Create new migrations to modify schema
-2. **Test migrations** - Always test on a copy of production data first
-3. **Backup before migrating** - Backup production database before applying migrations
-4. **Review changes** - Review all migrations before applying to production
-5. **Version control** - Keep migrations in version control (they are!)
-6. **Document changes** - Add comments to complex migrations
-
-## Development Workflow
-
-1. Create new migration file with timestamp:
-   ```bash
-   touch migrations/$(date +%Y%m%d%H%M%S)_description.sql
-   ```
-
-2. Write migration SQL (follow existing patterns)
-
-3. Test migration:
-   ```bash
-   sqlx migrate run
-   ```
-
-4. Verify changes:
-   ```bash
-   psql -U postgres -d attune
-   \d+ attune.table_name
-   ```
-
-5. Commit to version control
-
-## Production Deployment
-
-1. **Backup** production database
-2. **Review** all pending migrations
-3. **Test** migrations on staging environment with production data copy
-4. **Schedule** maintenance window if needed
-5. **Apply** migrations:
-   ```bash
-   sqlx migrate run
-   ```
-6. **Verify** application functionality
-7. **Monitor** for errors in logs
-
-## Troubleshooting
-
-### Migration already applied
-
-If you need to re-run a migration:
-
-```bash
-# Remove from migration tracking (SQLx)
-psql -U postgres -d attune -c "DELETE FROM _sqlx_migrations WHERE version = 20250101000001;"
-
-# Then re-run
-sqlx migrate run
-```
-
-### Permission denied
-
-Ensure the PostgreSQL user has sufficient permissions:
-
-```sql
-GRANT ALL PRIVILEGES ON DATABASE attune TO postgres;
-GRANT ALL PRIVILEGES ON SCHEMA attune TO postgres;
-```
-
-### Connection refused
-
-Check PostgreSQL is running:
-
-```bash
-# Linux/macOS
-pg_ctl status
-sudo systemctl status postgresql
-
-# Check if listening
-psql -U postgres -c "SELECT version();"
-```
-
-### Foreign key constraint violations
-
-Ensure migrations run in correct order. The consolidated migrations handle forward references correctly:
-- Migration 2 creates tables with forward references (commented as such)
-- Migration 3 and 4 add the foreign key constraints back

-```
-
-## Workflow Orchestration
-
-Migration 4 includes comprehensive workflow orchestration support:
-- **workflow_definition**: Stores parsed YAML workflow definitions with tasks, variables, and transitions
-- **workflow_execution**: Tracks runtime state including current/completed/failed tasks and variables
-- **workflow_task_execution**: Individual task execution tracking with retry and timeout support
-- **Action table extensions**: `is_workflow` and `workflow_def` columns link actions to workflows
-- **Helper views**: Three views for querying workflow state (summary, task detail, action links)
-
-## Queue Statistics
-
-Migration 5 includes the queue_stats table for execution ordering:
-- Tracks per-action queue length, active executions, and concurrency limits
-- Enables FIFO queue management with database persistence
-- Supports monitoring and API visibility of execution queues

 - `installation`: JSON describing installation requirements
+- `execution_config`: JSON describing how to execute code (interpreter, environment setup, dependencies). Runtimes without an `execution_config` (e.g., `core.builtin`) cannot execute actions — the worker skips them.
