refactor(smokes): Task 5 - Environment variable SSOT centralization

Create single source of truth for smoke test environment configuration:

**tools/smokes/v2/lib/env.sh** (new, 183 lines):
- Centralize 16 environment variables across 6 categories
- JoinIR development (NYASH_JOINIR_DEV, HAKO_JOINIR_STRICT)
- LLVM features (NYASH_LLVM_USE_HARNESS, NYASH_LLVM_BACKEND, etc.)
- Tmpdir EXDEV mitigation (TARGET_TMPDIR)
- Plugin loader strategy (NYASH_LOAD_NY_PLUGINS, NYASH_DISABLE_PLUGINS)
- Parser features (NYASH_FEATURES, using system variables)
- Debug features (NYASH_CLI_VERBOSE, etc.)

**Mode Presets**:
- dev: Verbose logging, unlimited fuel, JoinIR dev enabled
- integration: Moderate settings, JoinIR dev enabled
- quick: Minimal logging, fast execution

**Helper Functions**:
- setup_smoke_env [mode]: Configure environment for test profiles
- validate_env_setup: Validate configuration
- show_smoke_env: Display current configuration

**Documentation**:
- ENV_README.md: Comprehensive usage guide
- ENV_QUICK_START.md: Quick reference for script authors
- p1.5-task5-env-ssot.md: Implementation details and testing

Benefits:
- SSOT: Single file for all environment variables
- Sparrow prevention: No duplicate settings
- Clarity: Well-documented configuration
- Backward compatibility: Existing scripts work unchanged

Test Results:
- All environment presets work correctly
- Phase 131 smoke tests PASS
- Syntax validation for all shell files PASS

# Environment Variable SSOT - Quick Start
## TL;DR
All smoke test environment variables are now managed in `tools/smokes/v2/lib/env.sh`.
## For Script Authors
### Existing Scripts
**No changes required!** Scripts that source `test_runner.sh` or `llvm_exe_runner.sh` automatically get env.sh.
### New Scripts
```bash
#!/bin/bash
source "$(dirname "$0")/../lib/test_runner.sh" # Auto-sources env.sh
require_env || exit 2
# Your test code here
test_pass "my_test: passed"
```
### Phase 131+ Scripts (Require JoinIR Dev)
```bash
#!/bin/bash
source "$(dirname "$0")/../lib/test_runner.sh"
source "$(dirname "$0")/../lib/llvm_exe_runner.sh"
require_env || exit 2
# Enable JoinIR dev mode (required for Phase 131+)
require_joinir_dev
# Your test code here
```
## Common Variables (Auto-Set by env.sh)
```bash
NYASH_JOINIR_DEV=1 # JoinIR dev features
HAKO_JOINIR_STRICT=1 # Strict validation
NYASH_LLVM_USE_HARNESS=1 # Python llvmlite backend
NYASH_FEATURES=stage3 # Stage 3 parser
NYASH_ENABLE_USING=1 # Using system enabled
```
## Override Variables
To override defaults, set BEFORE sourcing:
```bash
export NYASH_CLI_VERBOSE=1 # Enable verbose mode
export NYASH_DEBUG_FUEL=unlimited # Unlimited debug fuel
source "$(dirname "$0")/../lib/test_runner.sh"
```
## Mode Presets
```bash
source "$(dirname "$0")/../lib/env.sh"
setup_smoke_env dev # Verbose, unlimited fuel
setup_smoke_env integration # Moderate settings
setup_smoke_env quick # Fast, minimal logging
```
## Debugging
```bash
# Show current configuration
source "$(dirname "$0")/../lib/env.sh"
show_smoke_env
# Validate configuration
source "$(dirname "$0")/../lib/env.sh"
validate_env_setup
```

# Smoke Test Environment Configuration (SSOT)
## Overview
`tools/smokes/v2/lib/env.sh` provides centralized environment variable configuration for all smoke tests. This prevents "sparrow bugs" (scattered duplicate configurations) and provides a single source of truth (SSOT) for smoke test environment.
## Usage
### Basic Usage
Source `env.sh` in your smoke script (already done in test_runner.sh and llvm_exe_runner.sh):
```bash
source "$(dirname "$0")/../lib/env.sh"
```
### Mode-Specific Configuration
Use `setup_smoke_env` to configure for different test profiles:
```bash
source "$(dirname "$0")/../lib/env.sh"
# Dev mode: verbose logging, unlimited fuel, JoinIR dev enabled
setup_smoke_env dev
# Integration mode: JoinIR dev enabled, moderate verbosity
setup_smoke_env integration
# Quick mode: minimal logging, fast execution
setup_smoke_env quick
```
### Display Current Configuration
```bash
source "$(dirname "$0")/../lib/env.sh"
show_smoke_env
```
Output:
```
[INFO] Smoke Environment Configuration (SSOT: lib/env.sh)
JoinIR Dev: NYASH_JOINIR_DEV=1
JoinIR Strict: HAKO_JOINIR_STRICT=1
LLVM Harness: NYASH_LLVM_USE_HARNESS=1
LLVM Backend: NYASH_LLVM_BACKEND=crate
Plugins: NYASH_DISABLE_PLUGINS=0
Debug Fuel: NYASH_DEBUG_FUEL=10000
Verbose: NYASH_CLI_VERBOSE=0
```
## Environment Variables (SSOT)
### JoinIR Development Mode (Phase 131+)
Required for dev-only fixtures using normalized shadow control flow.
- `NYASH_JOINIR_DEV`: Enable dev-only JoinIR features (default: 1)
- `HAKO_JOINIR_STRICT`: Enable strict JoinIR validation (default: 1)
### LLVM Features
- `NYASH_LLVM_USE_HARNESS`: Use Python llvmlite backend (default: 1)
- `NYASH_LLVM_BACKEND`: Backend selection - crate|python|auto (default: crate)
- `NYASH_LLVM_VERIFY`: Enable LLVM verification (default: 0)
- `NYASH_LLVM_VERIFY_IR`: Enable IR verification (default: 0)
### Tmpdir EXDEV Mitigation
Prevents "Invalid cross-device link" errors when /tmp is on different filesystem.
- `TARGET_TMPDIR`: Override tmpdir location (default: current directory)
### Plugin Loader Strategy
- `NYASH_LOAD_NY_PLUGINS`: Load .hako-based plugins from nyash.toml (default: 0)
- `NYASH_DISABLE_PLUGINS`: Disable all plugins except core builtins (default: 0)
### Parser Features
- `NYASH_FEATURES`: Parser feature level (default: stage3)
- `NYASH_ENABLE_USING`: Enable using system (default: 1)
- `HAKO_ENABLE_USING`: Enable using system (default: 1)
- `NYASH_ALLOW_USING_FILE`: Allow file imports (default: 1)
- `HAKO_ALLOW_USING_FILE`: Allow file imports (default: 1)
- `NYASH_USING_AST`: Use AST mode for using (default: 1)
### Debug Features
Controlled by `SMOKE_DEBUG=1` environment variable:
- `NYASH_CLI_VERBOSE`: Verbose CLI output (default: 0, dev mode: 1)
- `HAKO_TRACE_EXECUTION`: Trace execution (default: 0, debug mode: 1)
- `HAKO_VERIFY_SHOW_LOGS`: Show verification logs (default: 0, debug mode: 1)
- `NYASH_DEBUG_FUEL`: Debug fuel limit (default: 10000, dev mode: unlimited)
### Other Settings
- `HAKO_SILENT_TAGS`: Reduce log noise (default: 1)
## Validation
### Manual Validation
```bash
source "$(dirname "$0")/../lib/env.sh"
validate_env_setup
```
### Auto-Validation
Set `SMOKE_ENV_VALIDATE=1` to auto-validate on source:
```bash
export SMOKE_ENV_VALIDATE=1
source "$(dirname "$0")/../lib/env.sh"
# Validation runs automatically
```
## Mode Presets
### Dev Mode
```bash
setup_smoke_env dev
```
- Verbose: ON (NYASH_CLI_VERBOSE=1)
- Debug fuel: unlimited
- JoinIR dev: ON
### Integration Mode
```bash
setup_smoke_env integration
```
- Verbose: OFF (unless overridden)
- Debug fuel: 10000
- JoinIR dev: ON
### Quick Mode
```bash
setup_smoke_env quick
```
- Verbose: OFF
- Debug fuel: 10000
- Silent tags: ON (reduce noise)
## Migration Notes
### For Existing Scripts
Most scripts will automatically use env.sh via test_runner.sh or llvm_exe_runner.sh sourcing it. No changes required.
### For New Scripts
1. Source test_runner.sh (which sources env.sh):
```bash
source "$(dirname "$0")/../lib/test_runner.sh"
```
2. Optionally set mode if needed:
```bash
setup_smoke_env integration
```
3. Use require_joinir_dev for Phase 131+ fixtures:
```bash
require_joinir_dev
```
## Examples
### Basic Smoke Script (VM)
```bash
#!/bin/bash
source "$(dirname "$0")/../lib/test_runner.sh"
require_env || exit 2
# Test implementation
test_pass "my_test: passed"
```
### LLVM EXE Smoke Script
```bash
#!/bin/bash
source "$(dirname "$0")/../lib/test_runner.sh"
source "$(dirname "$0")/../lib/llvm_exe_runner.sh"
require_env || exit 2
llvm_exe_preflight_or_skip || exit 0
# Phase 131 requires dev mode
require_joinir_dev
# Test implementation
```
### Custom Mode Configuration
```bash
#!/bin/bash
source "$(dirname "$0")/../lib/test_runner.sh"
# Override specific variables after env.sh defaults
export NYASH_CLI_VERBOSE=1
export NYASH_DEBUG_FUEL="unlimited"
# Test implementation
```
## Troubleshooting
### Variables Not Set
Ensure env.sh is sourced before accessing variables:
```bash
# ✅ Correct
source "$(dirname "$0")/../lib/test_runner.sh"
echo "JoinIR dev: $NYASH_JOINIR_DEV"
# ❌ Wrong
echo "JoinIR dev: $NYASH_JOINIR_DEV" # Not set yet!
source "$(dirname "$0")/../lib/test_runner.sh"
```
### Mode Not Applied
Call setup_smoke_env AFTER sourcing env.sh:
```bash
# ✅ Correct
source "$(dirname "$0")/../lib/env.sh"
setup_smoke_env dev
# ❌ Wrong
setup_smoke_env dev # Function not defined yet!
source "$(dirname "$0")/../lib/env.sh"
```
### Defaults Overridden
env.sh uses `${VAR:-default}` pattern, so pre-set variables take precedence:
```bash
# Override before sourcing env.sh
export NYASH_JOINIR_DEV=0 # Disable dev mode
source "$(dirname "$0")/../lib/env.sh"
# NYASH_JOINIR_DEV will remain 0
```
## Design Principles
1. **SSOT (Single Source of Truth)**: All environment variable defaults in one place
2. **Fallback-Safe**: Uses `${VAR:-default}` pattern to allow overrides
3. **Mode-Based**: Pre-configured modes for common test scenarios
4. **Validation**: Built-in validation helpers to catch configuration issues
5. **Backward Compatible**: Existing scripts work without changes
## Related Files
- `tools/smokes/v2/lib/env.sh`: SSOT environment configuration
- `tools/smokes/v2/lib/test_runner.sh`: Core test runner (sources env.sh)
- `tools/smokes/v2/lib/llvm_exe_runner.sh`: LLVM EXE helpers (sources env.sh)
- `tools/build_llvm.sh`: LLVM build script (respects TARGET_TMPDIR from env.sh)
## Phase 131 Task 5 Implementation
This SSOT system was implemented as part of Phase 131 Task 5 to:
- Centralize environment variable configuration
- Prevent "sparrow bugs" (duplicate scattered settings)
- Enable easy modification of defaults across all tests
- Provide clear documentation of available settings
### Implementation Summary
- **New file**: `tools/smokes/v2/lib/env.sh` (180 lines)
- **Modified files**:
- `tools/smokes/v2/lib/llvm_exe_runner.sh`: Source env.sh, update require_joinir_dev
- `tools/smokes/v2/lib/test_runner.sh`: Source env.sh, update helper functions
- `tools/build_llvm.sh`: Support TARGET_TMPDIR from env.sh
### Testing
All existing smoke tests pass with the new SSOT system:
- ✅ Phase 131 VM smoke test
- ✅ Phase 131 LLVM EXE smoke test
- ✅ Environment variable validation
- ✅ Mode-specific configurations
