initial commit: @arbiter/core authorization engine with js-rigor hardening
Zanzibar-style authorization graph engine (direct/chain/TTU/defeasible/ binary modes, condensed snapshots, value relations) with 39 rigor test campaigns. Includes fixes for snapshot binary writer/reader format mismatch (snapshot-of-snapshot corruption), possibility write-boundary validation, empty-graph snapshot serialization, relation lookup cache direction collision, config-redefinition cache invalidation, binary threshold semantics, defeasible compiled routing, and comparator reason whitelisting.

* Targeted B2C Diagnostic Test
|
||||
*
|
||||
* Purpose: Diagnose why B2C scenario has:
|
||||
* 1. False negatives (over-refusing)
|
||||
* 2. Low QPS (1002 vs 17241 in enterprise)
|
||||
*
|
||||
* Hypothesis:
|
||||
* - SCC bug causing incorrect PLTC queries (fixed, but need to verify)
|
||||
* - Chain evaluation not finding paths that exist
|
||||
* - Execution path not using PLTC efficiently
|
||||
*
|
||||
* Approach:
|
||||
* 1. Small controlled graph (50 users, 200 files) for easy inspection
|
||||
* 2. Trace execution path for each query
|
||||
* 3. Measure time in each phase
|
||||
* 4. Verify SCC correctness
|
||||
* 5. Verify PLTC queries
|
||||
* 6. Verify chain evaluation

# AST Module - DSL Compiler for Zanzibar-Graph
|
||||
|
||||
This module provides a complete Abstract Syntax Tree (AST) system for parsing and compiling the Evidence DSL into rule configurations that interface with the zanzibar-graph authorization system.
|
||||
|
||||
## Overview
|
||||
|
||||
The AST module consists of three main components:
|
||||
|
||||
1. **Parser** - Converts DSL text into AST nodes
|
||||
2. **Generator** - Converts AST nodes into rule configurations
|
||||
3. **Compiler** - Orchestrates the parsing and generation process
|
||||
|
||||
## Architecture
|
||||
|
||||
```
|
||||
DSL Text → Parser → AST Nodes → Generator → Rule Configs → setRelationConfig()
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
- **Complete DSL Support** - Supports all DSL constructs from the specification
|
||||
- **Modular Design** - Clean separation of concerns with pluggable components
|
||||
- **Error Handling** - Comprehensive error reporting and validation
|
||||
- **Program Management** - Support for multiple compiled programs
|
||||
- **Rule Generation** - Automatic conversion to existing rule system
|
||||
- **Extensible** - Easy to add new node types and generators
|
||||
|
||||
## Quick Start
|
||||
|
||||
```javascript
|
||||
import { DSLCompiler } from './src/ast/index.js';
|
||||
|
||||
// Create compiler with arbiter instance
|
||||
const compiler = new DSLCompiler(arbiter);
|
||||
|
||||
// Compile DSL text
|
||||
const result = compiler.compile(dslText, 'my-program');
|
||||
|
||||
if (result.success) {
|
||||
console.log(`Generated ${result.generatedCount} rules`);
|
||||
} else {
|
||||
console.error('Compilation errors:', result.errors);
|
||||
}
|
||||
```
|
||||
|
||||
## Core Components
|
||||
|
||||
### 1. AST Nodes (`/nodes/`)
|
||||
|
||||
The AST nodes represent the parsed structure of the DSL:
|
||||
|
||||
- **BaseNode** - Base class for all AST nodes
|
||||
- **ProgramNode** - Root node containing all definitions
|
||||
- **DefinitionNode** - Type definitions with fields and behaviors
|
||||
- **FactNode** - Fact definitions with parameters and properties
|
||||
- **EvidenceNode** - Evidence definitions with bodies
|
||||
- **MeasureNode** - Measure definitions for value collection
|
||||
- **ExpressionNode** - Expressions, variables, and literals
|
||||
- **And many more...**
|
||||
|
||||
### 2. Parser (`/parser/`)
|
||||
|
||||
The DSL parser converts text into AST nodes:
|
||||
|
||||
```javascript
|
||||
import { DSLParser } from './parser/DSLParser.js';
|
||||
|
||||
const parser = new DSLParser();
|
||||
const program = parser.parse(dslText);
|
||||
```
|
||||
|
||||
### 3. Generator (`/generator/`)
|
||||
|
||||
The rule generator converts AST nodes into rule configurations:
|
||||
|
||||
```javascript
|
||||
import { RuleGenerator } from './generator/RuleGenerator.js';
|
||||
|
||||
const generator = new RuleGenerator(arbiter);
|
||||
const result = generator.generateRules(program);
|
||||
```
|
||||
|
||||
### 4. Compiler (`DSLCompiler.js`)
|
||||
|
||||
The main compiler orchestrates the entire process:
|
||||
|
||||
```javascript
|
||||
import { DSLCompiler } from './DSLCompiler.js';
|
||||
|
||||
const compiler = new DSLCompiler(arbiter);
|
||||
const result = compiler.compile(dslText, 'program-name');
|
||||
```
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Compilation
|
||||
|
||||
```javascript
|
||||
const dsl = `
|
||||
definition User {
|
||||
role: string
|
||||
isActive: boolean
|
||||
}
|
||||
|
||||
fact hasRole(user: User, role: string) CACHE eager
|
||||
|
||||
evidence canRead(user: User, doc: Document) {
|
||||
hasRole(user, 'admin')
|
||||
}
|
||||
`;
|
||||
|
||||
const result = compiler.compile(dsl, 'auth');
|
||||
```
|
||||
|
||||
### Complex DSL with Defeasible Logic
|
||||
|
||||
```javascript
|
||||
const complexDSL = `
|
||||
evidence canAccessCritical(user: User, resource: Resource) {
|
||||
// Strict requirement
|
||||
ALWAYS user.isActive
|
||||
|
||||
// Defeasible access
|
||||
WHEN hasRole(user, 'admin') UNLESS isSuspended(user)
|
||||
|
||||
// Requirements
|
||||
REQUIRES hasClearance(user, resource.level)
|
||||
|
||||
// Fusion evidence
|
||||
fusion majority {
|
||||
user.isTrusted
|
||||
user.hasRecentActivity
|
||||
}
|
||||
}
|
||||
`;
|
||||
|
||||
const result = compiler.compile(complexDSL, 'critical-access');
|
||||
```
|
||||
|
||||
### Multiple Programs
|
||||
|
||||
```javascript
|
||||
const programs = {
|
||||
'auth': `
|
||||
fact hasRole(user: User, role: string)
|
||||
evidence canRead(user: User, doc: Document) {
|
||||
hasRole(user, 'admin')
|
||||
}
|
||||
`,
|
||||
'finance': `
|
||||
fact hasBalance(user: User, amount: number)
|
||||
evidence canWithdraw(user: User, amount: number) {
|
||||
hasBalance(user, amount)
|
||||
}
|
||||
`
|
||||
};
|
||||
|
||||
const result = compiler.compileMultiple(programs);
|
||||
```

|
||||
## Supported DSL Constructs
|
||||
|
||||
### Type Definitions
|
||||
|
||||
```typescript
|
||||
definition User {
|
||||
role: string
|
||||
isActive: boolean
|
||||
lastActive: timestamp BEHAVES {
|
||||
decaying down hourly
|
||||
} CACHE lazy
|
||||
}
|
||||
```
|
||||
|
||||
### Facts
|
||||
|
||||
```typescript
|
||||
fact hasRole(user: User, role: string) CACHE eager
|
||||
fact isMember(user: User, group: Group) transitive CACHE lazy
|
||||
```
|
||||
|
||||
### Evidence
|
||||
|
||||
```typescript
|
||||
evidence canRead(user: User, doc: Document) {
|
||||
// Direct evidence
|
||||
owns(user, doc)
|
||||
|
||||
// Pattern matching
|
||||
isMember(user, *group) {
|
||||
canRead(group, doc)
|
||||
} limit 5
|
||||
|
||||
// Defeasible logic
|
||||
WHEN hasRole(user, 'admin') UNLESS isSuspended(user)
|
||||
}
|
||||
```
|
||||
|
||||
### Measures
|
||||
|
||||
```typescript
|
||||
measure userBalance(user: User) {
|
||||
user.balance
|
||||
} PROVIDES number
|
||||
|
||||
measure userPermissions(user: User) {
|
||||
fusion max {
|
||||
user.role.permissions
|
||||
user.group.permissions
|
||||
}
|
||||
} PROVIDES Permission[]
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The compiler provides comprehensive error handling:
|
||||
|
||||
```javascript
|
||||
const result = compiler.compile(dslText);
|
||||
|
||||
if (!result.success) {
|
||||
console.error('Compilation failed:');
|
||||
result.errors.forEach(error => console.error(` - ${error}`));
|
||||
}
|
||||
|
||||
if (result.warnings.length > 0) {
|
||||
console.warn('Warnings:');
|
||||
result.warnings.forEach(warning => console.warn(` - ${warning}`));
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Run the test suite:
|
||||
|
||||
```javascript
|
||||
import { runDSLCompilerTests } from './tests/DSLCompiler.test.js';
|
||||
|
||||
const testResults = runDSLCompilerTests(arbiter);
|
||||
console.log('Test Results:', testResults);
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
See the examples directory for comprehensive usage examples:
|
||||
|
||||
- `examples/DSLExample.js` - Complete usage examples
|
||||
- `tests/DSLCompiler.test.js` - Test suite
|
||||
|
||||
## Integration with Existing System
|
||||
|
||||
The AST module integrates seamlessly with the existing zanzibar-graph system:
|
||||
|
||||
1. **Parser** converts DSL text to AST nodes
|
||||
2. **Generator** converts AST nodes to rule configurations
|
||||
3. **Compiler** applies rules via `arbiter.setRelationConfig()`
|
||||
|
||||
The generated rules are compatible with all existing rule types:
|
||||
- Direct rules
|
||||
- Computed rules
|
||||
- Parent rules
|
||||
- Tuple-to-userset rules
|
||||
- Similarity rules
|
||||
- Multi-hop rules
|
||||
- Logical operators
|
||||
- Defeasible logic
|
||||
|
||||
## Extensibility
|
||||
|
||||
The AST system is designed to be extensible:
|
||||
|
||||
1. **Add new node types** by extending `BaseNode`
|
||||
2. **Add new parsers** by extending `DSLParser`
|
||||
3. **Add new generators** by extending `RuleGenerator`
|
||||
4. **Add new compilers** by extending `DSLCompiler`
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Lazy evaluation** - AST nodes are created on demand
|
||||
- **Efficient parsing** - Token-based parsing with minimal memory usage
|
||||
- **Rule caching** - Generated rules are cached for reuse
|
||||
- **Batch processing** - Support for compiling multiple programs at once
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- **Incremental compilation** - Only recompile changed parts
|
||||
- **Parallel processing** - Compile multiple programs in parallel
|
||||
- **Advanced optimizations** - Rule optimization and simplification
|
||||
- **IDE support** - Language server protocol support
|
||||
- **Visualization** - AST visualization tools
|
||||
|
||||
## Contributing
|
||||
|
||||
When contributing to the AST module:
|
||||
|
||||
1. Follow the existing code structure
|
||||
2. Add comprehensive tests for new features
|
||||
3. Update documentation
|
||||
4. Ensure backward compatibility
|
||||
5. Follow the established patterns

|
||||
## Test Philosophy
|
||||
|
||||
### Structural Linguistic Approach
|
||||
The tests follow a structural linguistic methodology:
|
||||
|
||||
1. **Phonological Level**: Basic lexical elements (identifiers, literals)
|
||||
2. **Morphological Level**: Word formation (operators, keywords)
|
||||
3. **Syntactic Level**: Grammar rules (expressions, statements)
|
||||
4. **Semantic Level**: Meaning (types, behaviors, logic)
|
||||
5. **Pragmatic Level**: Usage (integration, real-world scenarios)
|
||||
|
||||
### Incremental Complexity
|
||||
Tests progress from simple to complex:
|
||||
- **Level 1**: Lexical primitives
|
||||
- **Level 2**: Basic expressions
|
||||
- **Level 3**: Type system
|
||||
- **Level 4**: Fact system
|
||||
- **Level 5**: Evidence system
|
||||
- **Level 6**: Measure system
|
||||
- **Level 7**: Complex integration
|
||||
|
||||
### Comprehensive Coverage
|
||||
Each language feature is tested for:
|
||||
- **Valid cases**: Correct syntax and semantics
|
||||
- **Invalid cases**: Error handling and recovery
|
||||
- **Edge cases**: Boundary conditions
|
||||
- **Integration**: Multi-feature combinations
|
||||
|
||||
## Running Tests
|
||||
|
||||
### Prerequisites
|
||||
- Node.js environment
|
||||
- Arbiter instance for testing
|
||||
- All dependencies installed
|
||||
|
||||
### Basic Usage
|
||||
```bash
|
||||
# Run all tests
|
||||
npm test
|
||||
|
||||
# Run specific test file
|
||||
node src/ast/tests/StructuralLinguisticTests.js
|
||||
|
||||
# Run with specific arbiter
|
||||
node -e "
|
||||
import { runAllTests } from './src/ast/tests/TestRunner.js';
|
||||
const results = runAllTests(arbiter);
|
||||
console.log(results);
|
||||
"
|
||||
```
|
||||
|
||||
### Test Output
|
||||
The test runner provides:
|
||||
- **Progress indicators**: Real-time test execution
|
||||
- **Detailed results**: Pass/fail status for each test
|
||||
- **Error reporting**: Specific error messages for failures
|
||||
- **Performance metrics**: Execution time for each suite
|
||||
- **Coverage analysis**: Language feature coverage
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding new tests:
|
||||
1. Follow the structural linguistic approach
|
||||
2. Test both valid and invalid cases
|
||||
3. Include error handling tests
|
||||
4. Document test purpose and expected behavior
|
||||
5. Maintain incremental complexity
|
||||
6. Update coverage documentation
|
||||
|
||||
## Test Maintenance
|
||||
|
||||
- **Regular Updates**: Keep tests current with language changes
|
||||
- **Performance Monitoring**: Track test execution time
|
||||
- **Coverage Analysis**: Ensure comprehensive feature coverage
|
||||
- **Error Handling**: Validate error messages and recovery
|
||||
- **Integration Testing**: Test real-world scenarios
