+### 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`)

Configured via `execution_config` JSONB (interpreter, environment setup, dependency management). No type distinction; whether a runtime is executable is determined by its `execution_config` content.

 - **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:

-# Optimized Multi-stage Dockerfile for Attune workers
-# This Dockerfile minimizes layer invalidation by selectively copying only required crates
+# Multi-stage Dockerfile for Attune worker service
 #
-# Key optimizations:
-# 1. Copy only Cargo.toml files first to cache dependency downloads
-# 2. Build dummy binaries to cache compiled dependencies
-# 3. Copy only worker and common crates (not all crates)
-# 4. Use BuildKit cache mounts for cargo registry and build artifacts
+# Simple and robust: build the entire workspace, then copy the worker binary
+# into different runtime base images depending on language support needed.
+# No dummy source compilation, no selective crate copying, no fragile hacks.
 #
-# Supports building different worker variants with different runtime capabilities
+# Targets:
+#   worker-base   - Shell only (lightweight)
+#   worker-python - Shell + Python
+#   worker-node   - Shell + Node.js
+#   worker-full   - Shell + Python + Node.js + Native
 #
 # Usage:
-#   docker build --target worker-base -t attune-worker:base -f docker/Dockerfile.worker.optimized .
-#   docker build --target worker-python -t attune-worker:python -f docker/Dockerfile.worker.optimized .
-#   docker build --target worker-node -t attune-worker:node -f docker/Dockerfile.worker.optimized .
-#   docker build --target worker-full -t attune-worker:full -f docker/Dockerfile.worker.optimized .
+#   DOCKER_BUILDKIT=1 docker build --target worker-base -t attune-worker:base -f docker/Dockerfile.worker.optimized .
+#   DOCKER_BUILDKIT=1 docker build --target worker-python -t attune-worker:python -f docker/Dockerfile.worker.optimized .

+#   DOCKER_BUILDKIT=1 docker build --target worker-full -t attune-worker:full -f docker/Dockerfile.worker.optimized .

-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

-# 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
-

+# Fix: Pack Installation Virtualenv Ordering & FK ON DELETE Constraints
+
+**Date:** 2026-02-05
+
+## Problems
+
+### 1. Virtualenv Not Created at Permanent Location
+
+When installing a Python pack (e.g., `python_example`), no virtualenv was created at the permanent storage location. Attempting to run an action yielded:
+
+```json
+{
+  "error": "Execution failed during preparation",
+  "succeeded": false
+}
+```
+
+### 2. Pack Deletion Blocked by Foreign Key Constraints
+
+Deleting a pack that had been used (with executions) failed with:
+
+```json
+{
+  "error": "Constraint violation: execution_action_fkey",
+  "code": "CONFLICT"
+}
+```
+
+## Root Causes
+
+### Virtualenv Ordering Bug
+
+In `install_pack` (`crates/api/src/routes/packs.rs`), the operation ordering was incorrect:
+
+1. Pack downloaded to temp directory (`/tmp/attune-pack-installs/...`)
+2. `register_pack_internal(temp_path)` called — creates DB record **and sets up virtualenv at temp path**
+3. `storage.install_pack()` copies pack from temp to permanent storage (`packs/{pack_ref}/`)
+4. Temp directory cleaned up
+
+Python virtualenvs are **not relocatable** — they contain hardcoded paths in shebang lines, `pyvenv.cfg`, and pip scripts. The copied `.venv` was non-functional.
+
+### Missing ON DELETE Clauses on Foreign Keys
+
+Several foreign key constraints in the schema had no `ON DELETE` behavior (defaulting to `RESTRICT`), which blocked cascading deletes:
+
+- `execution.action` → `action(id)` — **no ON DELETE** (blocks action deletion)
+- `execution.parent` → `execution(id)` — **no ON DELETE**
+- `execution.enforcement` → `enforcement(id)` — **no ON DELETE**
+- `rule.action` → `action(id)` — **no ON DELETE**, also `NOT NULL`
+- `rule.trigger` → `trigger(id)` — **no ON DELETE**, also `NOT NULL`
+- `event.source` → `sensor(id)` — **no ON DELETE**
+- `workflow_execution.workflow_def` → `workflow_definition(id)` — **no ON DELETE**
+
+When deleting a pack, the cascade deleted actions (`action.pack ON DELETE CASCADE`), but executions referencing those actions blocked the delete.
+
+## Fixes
+
+### 1. Pack Installation Ordering
+
+Restructured `install_pack` to move the pack to permanent storage **before** calling `register_pack_internal`:
+
+1. Pack downloaded to temp directory
+2. `pack.yaml` read to extract `pack_ref`
+3. **Pack moved to permanent storage** (`packs/{pack_ref}/`)
+4. `register_pack_internal(permanent_path)` called — virtualenv creation and dependency installation now happen at the final location
+5. Temp directory cleaned up
+
+Added error handling to clean up permanent storage if registration fails after the move.
+
+### 2. Foreign Key ON DELETE Fixes (Merged into Original Migrations)
+
+Fixed all missing ON DELETE behaviors directly in the original migration files (requires DB rebuild):
+
+| Table.Column | Migration File | ON DELETE | Notes |
+|---|---|---|---|
+| `execution.action` | `000006_execution_system` | `SET NULL` | Already nullable; `action_ref` text preserved |
+| `execution.parent` | `000006_execution_system` | `SET NULL` | Already nullable |
+| `execution.enforcement` | `000006_execution_system` | `SET NULL` | Already nullable |
+| `rule.action` | `000006_execution_system` | `SET NULL` | Made nullable; `action_ref` text preserved |
+| `rule.trigger` | `000006_execution_system` | `SET NULL` | Made nullable; `trigger_ref` text preserved |
+| `event.source` | `000004_trigger_sensor_event_rule` | `SET NULL` | Already nullable; `source_ref` preserved |
+| `workflow_execution.workflow_def` | `000007_workflow_system` | `CASCADE` | Meaningless without definition |
+
+### 3. Model & Code Updates
+
+- **Rule model** (`crates/common/src/models.rs`): Changed `action: Id` and `trigger: Id` to `Option<Id>`
+- **RuleResponse DTO** (`crates/api/src/dto/rule.rs`): Changed `action` and `trigger` to `Option<i64>`
+- **Enforcement processor** (`crates/executor/src/enforcement_processor.rs`): Added guards to skip execution when a rule's action or trigger has been deleted (SET NULL)
+- **Pack delete endpoint** (`crates/api/src/routes/packs.rs`): Added filesystem cleanup to remove pack directory from permanent storage on deletion
+
+### 4. Test Updates
+
+- `crates/common/tests/rule_repository_tests.rs`: Updated assertions to use `Some(id)` for nullable fields
+- `crates/executor/src/enforcement_processor.rs` (tests): Updated test Rule construction with `Some()` wrappers
+
+## Files Changed
+
+- `migrations/20250101000004_trigger_sensor_event_rule.sql` — Added `ON DELETE SET NULL` to `event.source`
+- `migrations/20250101000006_execution_system.sql` — Added `ON DELETE SET NULL` to `execution.action`, `.parent`, `.enforcement`; made `rule.action`/`.trigger` nullable with `ON DELETE SET NULL`
+- `migrations/20250101000007_workflow_system.sql` — Added `ON DELETE CASCADE` to `workflow_execution.workflow_def`
+- `crates/api/src/routes/packs.rs` — Reordered `install_pack`; added pack directory cleanup on delete
+- `crates/api/src/dto/rule.rs` — Made `action`/`trigger` fields optional in `RuleResponse`
+- `crates/common/src/models.rs` — Made `Rule.action`/`Rule.trigger` `Option<Id>`
+- `crates/executor/src/enforcement_processor.rs` — Handle nullable action/trigger in enforcement processing
+- `crates/common/tests/rule_repository_tests.rs` — Fixed test assertions
+
+## Design Philosophy
+
+Historical records (executions, events, enforcements) are preserved when their referenced entities are deleted. The text ref fields (`action_ref`, `trigger_ref`, `source_ref`, etc.) retain the reference for auditing, while the FK ID fields are set to NULL. Rules with deleted actions or triggers become non-functional but remain in the database for traceability.
+
+## Verification
+
+- `cargo check --all-targets --workspace` — zero warnings
+- `cargo test --workspace --lib` — all 358 unit tests pass

+# Work Summary: Pack Installation Fixes (2026-02-13)
+
+## Problem
+
+The `/packs/install` web UI page was completely non-functional when attempting to install packs from git repositories. Multiple cascading issues prevented successful pack installation via the API.
+
+## Issues Fixed
+
+### 1. `git` binary missing from API container
+**Error:** `Failed to execute git clone: No such file or directory (os error 2)`
+
+The `install_from_git` method in `PackInstaller` runs `Command::new("git")` to clone repositories, but the runtime Docker image (`debian:bookworm-slim`) did not include `git`.
+
+**Fix:** Added `git` to the runtime stage's `apt-get install` in `docker/Dockerfile.optimized`.
+
+### 2. Pack tests ran before pack files existed at expected location
+**Error:** `Pack directory not found: /opt/attune/packs/python_example`
+
+The `execute_and_store_pack_tests` function always constructed the pack path as `packs_base_dir/pack_ref`, but during installation the pack files were still in a temp directory. The move to permanent storage happened *after* test execution.
+
+**Fix:**
+- Added `execute_pack_tests_at(pack_dir, ...)` method to `TestExecutor` that accepts an explicit directory path
+- Added `pack_dir_override: Option<&std::path::Path>` parameter to `execute_and_store_pack_tests`
+- `register_pack_internal` now passes the actual pack path through to tests
+
+### 3. Missing test config treated as installation failure
+**Error:** `No testing configuration found in pack.yaml for pack 'python_example'`
+
+Packs without a `testing` section in `pack.yaml` could not be installed without `force=true`, because the absence of test config was returned as an error.
+
+**Fix:** Changed `execute_and_store_pack_tests` return type from `Result<PackTestResult>` to `Option<Result<PackTestResult>>`. Returns `None` when no testing config exists or testing is disabled, which the caller treats as "no tests to run" (success). All `?` operators were replaced with explicit `match`/`return` to work with the `Option<Result<...>>` return type.
+
+### 4. Packs volume mounted read-only on API container
+**Error:** `Read-only file system (os error 30)`
+
+The `packs_data` volume was mounted as `:ro` on the API container, and files were owned by root (written by `init-packs` running as root). The API service (running as user `attune`, uid 1000) could not write.
+
+**Fix:**
+- Changed volume mount from `packs_data:/opt/attune/packs:ro` to `:rw` in `docker-compose.yaml`
+- Added `chown -R 1000:1000 "$TARGET_PACKS_DIR"` to `docker/init-packs.sh` (runs after initial pack copy and again after all packs loaded)
+
+### 5. Pack components not loaded into database
+**Symptom:** Pack installed successfully but actions, triggers, and sensors not visible in the UI.
+
+The `register_pack_internal` function only created the `pack` table record and synced workflows. It never loaded the pack's individual components (actions, triggers, sensors) from their YAML definition files. This was previously only handled by the Python `load_core_pack.py` script during `init-packs`.
+
+**Fix:** Created `PackComponentLoader` in `crates/common/src/pack_registry/loader.rs` — a Rust-native pack component loader that:
+- Reads `triggers/*.yaml` and creates trigger records via `TriggerRepository`
+- Reads `actions/*.yaml` and creates action records with full field support (parameter_delivery, parameter_format, output_format) via direct SQL
+- Reads `sensors/*.yaml` and creates sensor records via `SensorRepository`, resolving trigger and runtime references
+- Loads in dependency order: triggers → actions → sensors
+- Skips components that already exist (idempotent)
+- Resolves runtime IDs by looking up common ref patterns (e.g., `shell` → `core.action.shell`)
+
+Integrated into `register_pack_internal` so both the `/packs/install` and `/packs/register` endpoints load components.
+
+### 6. Pack stored with version suffix in directory name
+**Symptom:** Pack stored at `python_example-1.0.0` but workers/sensors look for `python_example`.
+
+`PackStorage::install_pack` was called with `Some(&pack.version)`, creating a versioned directory name. The rest of the system expects `packs_base_dir/pack_ref` without version.
+
+**Fix:** Changed to `install_pack(&installed.path, &pack.r#ref, None)` to match the system convention.
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `docker/Dockerfile.optimized` | Added `git` to runtime dependencies |
+| `docker/init-packs.sh` | Added `chown -R 1000:1000` for attune user write access |
+| `docker-compose.yaml` | Changed packs volume mount from `:ro` to `:rw` on API |
+| `crates/common/src/test_executor.rs` | Added `execute_pack_tests_at` method |
+| `crates/common/src/pack_registry/loader.rs` | **New file** — `PackComponentLoader` |
+| `crates/common/src/pack_registry/mod.rs` | Added `loader` module and re-exports |
+| `crates/api/src/routes/packs.rs` | Fixed test execution path, no-test-config handling, component loading, storage path |

+Completed the refactoring to externalize runtime environments (virtualenvs, node_modules, etc.) from pack directories to a dedicated `runtime_envs_dir`. This ensures pack directories remain clean and read-only while isolated runtime environments are managed at a configurable external location.
+
+## Problem
+
+Previously, runtime environments (e.g., Python virtualenvs) were created inside pack directories at `{pack_dir}/.venv`. This had several issues:
+
+1. **Docker incompatibility**: Pack volumes are mounted read-only (`:ro`) in worker containers, preventing environment creation
+2. **API service failures**: The API container doesn't have Python installed, so `python3 -m venv` failed silently during pack registration
+3. **Dirty pack directories**: Mixing generated environments with pack source files
+4. **Missing `runtime_envs_dir` parameter**: `ProcessRuntime::new()` was updated to accept 4 arguments but callers were still passing 3, causing compile errors
+
+## Changes
+
+### Compile Fixes
+
+- **`crates/worker/src/service.rs`**: Added `runtime_envs_dir` from config and passed as 4th argument to `ProcessRuntime::new()`
+- **`crates/worker/src/runtime/local.rs`**: Added `PathBuf::from("/opt/attune/runtime_envs")` as 4th argument to `ProcessRuntime::new()` in `LocalRuntime::new()`
+- **`crates/worker/src/runtime/process.rs`**: Suppressed `dead_code` warning on `resolve_pack_dir` (tested utility method kept for API completeness)
+
+### Configuration
+
+- **`config.docker.yaml`**: Added `runtime_envs_dir: /opt/attune/runtime_envs`
+- **`config.development.yaml`**: Added `runtime_envs_dir: ./runtime_envs`
+- **`config.test.yaml`**: Added `runtime_envs_dir: /tmp/attune-test-runtime-envs`
+- **`config.example.yaml`**: Added documented `runtime_envs_dir` setting with explanation
+- **`crates/common/src/config.rs`**: Added `runtime_envs_dir` field to test `Config` struct initializers
+
+### Docker Compose (`docker-compose.yaml`)
+
+- Added `runtime_envs` named volume
+- Mounted `runtime_envs` volume at `/opt/attune/runtime_envs` in:
+  - `api` (for best-effort bare-metal env setup)
+  - `worker-shell`, `worker-python`, `worker-node`, `worker-full` (for on-demand env creation)
+
+### API Pack Registration (`crates/api/src/routes/packs.rs`)
+
+Updated the best-effort environment setup during pack registration to use external paths:
+- Environment directory computed as `{runtime_envs_dir}/{pack_ref}/{runtime_name}` instead of `{pack_dir}/.venv`
+- Uses `build_template_vars_with_env()` for proper template variable resolution with external env_dir
+- Creates parent directories before attempting environment creation
+- Checks `env_dir.exists()` directly instead of legacy `resolve_env_dir()` for dependency installation
+
+### ProcessRuntime `can_execute` Fix (`crates/worker/src/runtime/process.rs`)
+
+Fixed a pre-existing logic issue where `can_execute` would fall through from a non-matching runtime_name to extension-based matching. When an explicit `runtime_name` is specified in the execution context, it is now treated as authoritative — the method returns the result of the name comparison directly without falling through to extension matching.
+
+### Test Updates
+
+- **`crates/worker/tests/dependency_isolation_test.rs`**: Full rewrite to use external `runtime_envs_dir`. All 17 tests pass. Key changes:
+  - Separate `packs_base_dir` and `runtime_envs_dir` temp directories
+  - `env_dir` computed as `runtime_envs_dir.join(pack_ref).join(runtime_name)`
+  - `setup_pack_environment(&pack_dir, &env_dir)` — now takes 2 arguments
+  - `environment_exists("pack_ref")` — now takes pack_ref string
+  - Assertions verify environments are created at external locations AND that pack directories remain clean
+- **`crates/worker/tests/security_tests.rs`**: Added 4th `runtime_envs_dir` argument to all `ProcessRuntime::new()` calls
+- **`crates/worker/tests/log_truncation_test.rs`**: Added 4th `runtime_envs_dir` argument to all `ProcessRuntime::new()` calls
+- **`crates/worker/src/runtime/process.rs`** (unit test): Added 4th argument to `test_working_dir_set_to_pack_dir`
+
+## Environment Path Pattern
+
+```
+{runtime_envs_dir}/{pack_ref}/{runtime_name}
+```
+
+Examples:
+- `/opt/attune/runtime_envs/python_example/python` (Docker)
+- `./runtime_envs/python_example/python` (development)
+- `/tmp/attune-test-runtime-envs/testpack/python` (tests)
+
+## Architecture Summary
+
+| Component | Old Behavior | New Behavior |
+|-----------|-------------|-------------|
+| Env location | `{pack_dir}/.venv` | `{runtime_envs_dir}/{pack_ref}/{runtime}` |
+| Pack directory | Modified by venv | Remains clean/read-only |
+| API setup | Pack-relative `build_template_vars` | External `build_template_vars_with_env` |
+| Worker setup | Did not create venv | Creates venv on-demand before first execution |
+| Docker volumes | Only `packs_data` | `packs_data` (ro) + `runtime_envs` (rw) |
+| Config | No `runtime_envs_dir` | Configurable with default `/opt/attune/runtime_envs` |
+
+## Test Results
+
+- **attune-common**: 125 passed, 0 failed
+- **attune-worker unit tests**: 76 passed, 0 failed, 4 ignored
+- **dependency_isolation_test**: 17 passed, 0 failed
+- **log_truncation_test**: 8 passed, 0 failed
+- **security_tests**: 5 passed, 2 failed (pre-existing, unrelated to this work)
+- **Workspace**: Zero compiler warnings
+
+## Pre-existing Issues (Not Addressed)
+
+- `test_shell_secrets_not_in_environ`: Shell secret delivery mechanism issue
+- `test_python_secrets_isolated_between_actions`: Python stdin secret reading doesn't match delivery mechanism

+# Runtime Type Removal, YAML Loading & Ref Format Cleanup
+
+**Date:** 2026-02-13
+
+## Problem
+
+Running a Python action failed with:
+```
+Runtime not found: No runtime found for action: python_example.hello (available: shell)
+```
+
+The worker only had the Shell runtime registered. Investigation revealed four interrelated bugs:
+
+1. **Runtime YAML files were never loaded into the database.** `PackComponentLoader::load_all()` loaded triggers, actions, and sensors but completely ignored the `runtimes/` directory. Files like `packs/core/runtimes/python.yaml` were dead weight.
+
+2. **`load_core_pack.py` only created Shell + Sensor Builtin runtimes** via hardcoded `ensure_shell_runtime()` and `ensure_sensor_runtime()` methods instead of reading from YAML files.
+
+3. **The worker filtered by `runtime_type == "action"`**, but this distinction (action vs sensor) was meaningless — a Python runtime should be usable for both actions and sensors.
+
+4. **Runtime ref naming mismatch.** The Python YAML uses `ref: core.python`, but `resolve_runtime_id("python")` only looked for `core.action.python` and `python` — neither matched.
+
+## Root Cause Analysis: `runtime_type` Was Meaningless
+
+The `runtime_type` column (`action` | `sensor`) conflated *what the runtime is used for* with *what the runtime is*. Analysis of all usages showed:
+
+- **Worker filter**: Only behavioral use — could be replaced by checking if `execution_config` has an interpreter configured.
+- **`RuntimeRepository::find_by_type` / `find_action_runtimes`**: Never called anywhere in the codebase. Tests for them were already commented out.
+- **`runtime_detection.rs`**: Was filtering by ref pattern (`NOT LIKE '%.sensor.builtin'`), not by `runtime_type`.
+- **`DependencyManager::runtime_type()`**: Completely unrelated concept (returns "python"/"nodejs" for language identification).
+
+The real distinction is whether a runtime has an `execution_config` with an interpreter — data that already exists. The column was redundant.
+
+## Changes
+
+### Column Removal: `runtime_type`
+
+| File | Change |
+|------|--------|
+| `migrations/20250101000002_pack_system.sql` | Removed `runtime_type` column, its CHECK constraint, and its index |
+| `crates/common/src/models.rs` | Removed `runtime_type` field from `Runtime` struct |
+| `crates/common/src/repositories/runtime.rs` | Removed `runtime_type` from `CreateRuntimeInput`, `UpdateRuntimeInput`, all SELECT/INSERT/UPDATE queries; removed `find_by_type()` and `find_action_runtimes()` |
+| `crates/worker/src/service.rs` | Replaced `runtime_type` filter with `execution_config` check (skip runtimes with empty config) |
+| `crates/worker/src/executor.rs` | Removed `runtime_type` from runtime SELECT query |
+| `crates/common/src/pack_environment.rs` | Removed `runtime_type` from runtime SELECT query |
+| `crates/common/src/runtime_detection.rs` | Removed `runtime_type` from runtime SELECT query |
+| `crates/common/tests/helpers.rs` | Removed `runtime_type` from `RuntimeFixture` |
+| `crates/common/tests/repository_runtime_tests.rs` | Removed `runtime_type` from test fixtures |
+| `crates/common/tests/repository_worker_tests.rs` | Removed `runtime_type` from test fixture |
+| `crates/common/tests/migration_tests.rs` | Removed stale `runtime_type_enum` from expected enums list |
+| `crates/executor/tests/fifo_ordering_integration_test.rs` | Removed `runtime_type` from test fixture |
+| `crates/executor/tests/policy_enforcer_tests.rs` | Removed `runtime_type` from test fixture |
+| `scripts/load_core_pack.py` | Removed `runtime_type` from INSERT/UPDATE queries |
+
+### Runtime Ref Format Cleanup
+
+Runtime refs now use a clean 2-part `{pack_ref}.{name}` format (e.g., `core.python`, `core.shell`, `core.builtin`). The old 3-part format with `action` or `sensor` segments (e.g., `core.action.shell`, `core.sensor.builtin`) is eliminated.
+
+| File | Change |
+|------|--------|
+| `packs/core/runtimes/sensor_builtin.yaml` | Renamed ref from `core.sensor.builtin` to `core.builtin` |
+| `crates/common/src/schema.rs` | Updated `validate_runtime_ref` to enforce 2-part `pack.name` format; updated tests |
+| `crates/common/src/runtime_detection.rs` | Removed `WHERE ref NOT LIKE '%.sensor.builtin'` filter — no ref-based filtering needed |
+| `crates/common/src/pack_registry/loader.rs` | Updated hardcoded sensor runtime ref to `core.builtin`; cleaned `resolve_runtime_id()` to use only `core.{name}` patterns (removed legacy `core.action.*` fallbacks) |
+| `scripts/load_core_pack.py` | Updated `core.sensor.builtin` references to `core.builtin` |
+| `crates/common/tests/repository_runtime_tests.rs` | Updated test refs from 3-part to 2-part format |
+| `crates/common/tests/repository_worker_tests.rs` | Updated test ref from 3-part to 2-part format |
+
+### Runtime YAML Loading
+
+| File | Change |
+|------|--------|
+| `crates/common/src/pack_registry/loader.rs` | Added `load_runtimes()` method to read `runtimes/*.yaml` and insert into DB; added `runtimes_loaded`/`runtimes_skipped` to `PackLoadResult` |
+| `crates/api/src/routes/packs.rs` | Updated log message to include runtime count |
+| `scripts/load_core_pack.py` | Replaced hardcoded `ensure_shell_runtime()`/`ensure_sensor_runtime()` with `upsert_runtimes()` that reads all YAML files from `runtimes/` directory; added `resolve_action_runtime()` for smart runtime resolution |
+
+### Error Reporting Improvement
+
+| File | Change |
+|------|--------|
+| `crates/worker/src/executor.rs` | `handle_execution_failure` now accepts an `error_message` parameter. Actual error messages from `prepare_execution_context` and `execute_action` failures are stored in the execution result instead of the generic "Execution failed during preparation". |
+
+## Component Loading Order
+
+`PackComponentLoader::load_all()` now loads in dependency order:
+1. **Runtimes** (no dependencies)
+2. **Triggers** (no dependencies)
+3. **Actions** (depend on runtimes)
+4. **Sensors** (depend on triggers and runtimes)
+
+## Deployment
+
+Requires database reset (`docker compose down -v && docker compose up -d`) since the migration changed (column removed).
+
+## Validation
+
+- Zero compiler errors, zero warnings
+- All 76 unit tests pass
+- Integration test failures are pre-existing (missing `attune_test` database)

+# Worker On-Demand Virtualenv Creation
+
+**Date:** 2026-02-14
+
+## Problem
+
+When installing Python packs via the API in Docker deployments, virtualenvs were never created. The API service attempted to run `python3 -m venv` during pack registration, but the API container (built from `debian:bookworm-slim`) does not have Python installed. The command failed silently (logged as a warning), and pack registration succeeded without a virtualenv.
+
+When the worker later tried to execute a Python action, it fell back to the system Python interpreter instead of using an isolated virtualenv with the pack's dependencies installed.
+
+## Root Cause
+
+The architecture had a fundamental mismatch: environment setup (virtualenv creation, dependency installation) was performed in the **API service** during pack registration, but the API container lacks runtime interpreters like Python. The **worker service** — which has Python installed — had no mechanism to create environments on demand.
+
+## Solution
+
+Moved the primary responsibility for runtime environment creation from the API service to the worker service:
+
+### Worker-Side: On-Demand Environment Creation
+
+**File:** `crates/worker/src/runtime/process.rs`
+
+Added environment setup at the beginning of `ProcessRuntime::execute()`. Before executing any action, the worker now checks if the runtime has environment configuration and ensures the environment exists:
+
+- Calls `setup_pack_environment()` which is idempotent — it creates the virtualenv only if it doesn't already exist
+- On failure, logs a warning and falls back to the system interpreter (graceful degradation)
+- The virtualenv is created at `{pack_dir}/.venv` inside the shared packs volume, making it accessible across container restarts
+
+### API-Side: Best-Effort with Clear Logging
+
+**File:** `crates/api/src/routes/packs.rs`
+
+Updated the API's environment setup to be explicitly best-effort:
+
+- Changed log levels from `warn` to `info` for expected failures (missing interpreter)
+- Added clear messaging that the worker will handle environment creation on first execution
+- Added guard to skip dependency installation when the environment directory doesn't exist (i.e., venv creation failed)
+- Preserved the setup attempt for non-Docker (bare-metal) deployments where the API host may have Python available
+
+## How It Works
+
+1. **Pack installation** (API): Registers pack in database, loads components, attempts environment setup (best-effort)
+2. **First execution** (Worker): Detects missing `.venv`, creates it via `python3 -m venv`, installs dependencies from `requirements.txt`
+3. **Subsequent executions** (Worker): `.venv` already exists, skips setup, resolves interpreter to `.venv/bin/python3`
+
+## Files Changed
+
+| File | Change |
+|------|--------|
+| `crates/worker/src/runtime/process.rs` | Added on-demand environment setup in `execute()` |
+| `crates/api/src/routes/packs.rs` | Updated logging and made environment setup explicitly best-effort |
+
+## Testing
+
+- All 75 worker unit tests pass
+- All 23 ProcessRuntime tests pass
+- Zero compiler warnings
