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.

||||
const results = runTestsByLevel(arbiter, 'focused');
|
||||
|
||||
// Run only integration tests
|
||||
const results = runTestsByLevel(arbiter, 'integration');
|
||||
```
|
||||
|
||||
## Language Feature Coverage

|
||||
|
||||
### ✅ Expression System

||||
- Arithmetic operators (+, -, *, /) with precedence
|
||||

|
||||
- Caching directives (eager, lazy)
|
||||
|
||||
### ✅ Fact System

|
||||
|
||||
## 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
|
||||

||||
|
||||
# Run specific test file
|
||||
node src/ast/tests/StructuralLinguisticTests.js
|
||||
|
||||
# Run with specific arbiter
|
||||
node -e "
|
||||
import { runAllTests } from '../../../../../lib/src/ast/tests/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

* rigor/authorization-graph.test.js — js-rigor property tests for the

* authorization graph semantics.
|

*
|
||||
* Properties verified (the core authorization-graph contract):
|
||||
*
|
||||
* - DIRECT: an existing edge grants with EXACTLY its possibility;
|
||||
* a different relation on the same pair denies (0).
|
||||
* - BOUNDS: every check result possibility is ∈ [0, 1].
|
||||
* - ABSENT: no edges → 0 for any relation.
|
||||
* - CHAIN (weakest link): a chain's possibility equals the MIN of the
|
||||
* edge possibilities along the traversed path (transitivity holds).
|
||||
* - MULTI-PATH (disjunctive): with parallel paths the possibility is the
|
||||
* MAX over paths of the per-path minimum.
|
||||
* - TUPLE-TO-USERSET: group membership grants the group's owned objects
|
||||
* at the weakest-link possibility.
|
||||
* - MUTATION: removing an edge invalidates a previously-granting check
|
||||
* (no stale cache grant).
|
||||
*
|
||||
* Each property runs through js-rigor's generator + bandit pipeline, so
|
||||
* boundary values (possibility 0/1, self-loops, multi-hop chains) are
|
||||
* exercised automatically, with shrinking on failure.

* rigor/binary-mode-parity.test.js — js-rigor property tests for binary

* (threshold) evaluation mode.
|

*
|

* Binary mode is a separate evaluation path (_checkBinary + binary rules
|

* short-circuit) with dual thresholds: allow when strength >=
|
||||
* minAllowPossibility, deny when deny-strength >= maxDenyPossibility.
|
||||
*
|
||||
* Properties verified:
|
||||
*
|
||||
* - BINARY-NORMAL AGREEMENT: for every config kind and threshold,
|
||||
* binary.allow === (normal-mode possibility >= minAllowPossibility)
|
||||
* and the reason string is consistent.
|
||||
* - CONTINUOUS POSSIBILITY: binary.possibility reports the real
|
||||
* continuous strength (=== normal-mode possibility), never a binarized
|
||||
* 0/1 — for direct, chain, and logical operator configs.
|
||||
* - EXCLUSION DUAL THRESHOLD: top-level exclusion sets deny exactly when
|
||||
* the negated child's strength >= maxDenyPossibility.
|
||||
* - FASTPATH THRESHOLD PARITY: fastPath:true + minPossibility evaluates
|
||||
* the same continuous possibility as normal mode.
|
||||
* - MUTATION FRESHNESS: after every mutation, binary and normal checks
|
||||
* agree, and binary reflects the new state even with caching enabled.

* - TTL CONTRACT: with an injected fake clock, cached entries expire at

* the configured TTL — an entry read after its TTL is reported
|
||||
* expired, never hit.
|

* - OVERRIDE + CACHE: relation-override configs (can_read → viewer)

*
|

* Redefining a relation's config must take effect immediately: checks

* Properties verified:
|

*
|
||||
* - REDEFINE PARITY: after every redefinition round, checks equal the
|
||||
* twin arbiter built fresh with the final config (for every config
|
||||
* kind transition, multiple users, and warm caches).
|

* - POST-REDEFINE MUTATIONS: mutations on the new base relations behave

* rigor/direct-rule.test.js — js-rigor property tests for DirectRule.
|

*
|

* DirectRule is the simplest authorization rule: it asks the relation manager
|
||||
* for a direct (src, rel, dst) tuple and returns a standardized result with
|
||||
* raw possibility values. Properties verified:
|
||||
*
|
||||
* - No relation → possibility=0, possibility_allow=0, possibility_deny=0,
|
||||
* meta.ruleType='direct', reason='no_relation'
|
||||
* - Relation present with strength s → possibility=s, possibility_allow=s,
|
||||
* possibility_deny=0, reason='exists'
|
||||
* - reverse=true routes the lookup to (objectId, rel, userId)
|
||||
* - fastPath with minPossibility threshold sets meta.earlyExit on hit
|
||||
* - collectValues=false suppresses collectedValues
|
||||
* - relation field precedence: rule.relation > rule.rel > rule.label >
|
||||
* rule.name > currentRelation
|
||||
* - possibility ∈ [0,1] is preserved through the result
|
||||
* - result shape is stable (always has the same keys)

* rigor/dsl-compiler.test.js — js-rigor property tests for the DSL compiler.
|

*
|
||||
* Validates that ADR-000 Evidence DSL v2 compiles to the documented engine rule
|
||||
* types. ADR-000 §"Mapping to Engine Rule Types" enumerates:
|
||||
* - DirectRule → { type: 'direct' }
|
||||
* - TupleToUsersetRule → { type: 'tuple_to_userset' }
|
||||
* - ParentRule → { type: 'parent' }
|
||||
* - MultiHopRule → { type: 'multi_hop' }
|
||||
* - ChainRule → { type: 'chain' }
|
||||
* - LogicalOperators → { type: 'logical' }
|
||||
* - RelationalComparator → { type: 'relational_comparator' }
|
||||
*
|
||||
* Properties verified per rule type:
|
||||
* - DSL snippet compiles successfully
|
||||
* - Generated rule's `type` matches the ADR-000 mapping for that shape
|
||||
* - Required fields (relation, comparator, never/always/when, etc.) are present
|
||||
*
|
||||
* Bug class targeted: RF-24 — DSL compiler mapping gaps. The original generator
|
||||
* emitted 5 of the 7 ADR-000 rule types; ChainRule and RelationalComparatorRule
|
||||
* were dropped on the floor (silent gap, no test caught it).

*
|

* The engine contract for addRelation()/removeRelation() writes:
|
||||
* - possibility must be a finite number in [0, 1]; anything else THROWS
|
||||
* and leaves the graph untouched (no partial writes).
|
||||
* - undefined possibility defaults to 1.0 (pre-existing contract).
|
||||
* - node keys and relation names are exact-match strings: a numeric key
|
||||
* is a DIFFERENT node than its string form (missing_node), and '|'
|
||||
* inside keys/relation names is harmless (keys are numeric ids in the

* cache layer, so delimiter injection is structurally impossible).
|

* Two arms:
|

* accepted, graph state preserved across failed writes.
|
||||
* 2. STATE PROPERTY CAMPAIGN — random add/check sequences against a mirror
|
||||
* model; the mirror independently classifies each possibility as
|
||||
* valid/invalid and the engine must agree exactly, plus check()
|
||||
* results always stay in [0, 1].

* - Size invariant: |nodes| === |nodeIdByKey| === |keyByNodeId|

* Properties verified:

*
|
||||
* - PERSISTENT OVER PARTIAL: when both a persistent fact and a partial
|
||||
* graph fact describe the same triple, the persistent fact wins by
|
||||
* trust precedence — the check reflects the persistent possibility
|
||||
* (even when it is 0).
|
||||
* - SURFACING: removing the persistent fact lets the partial fact
|
||||
* surface; the check then reflects the partial possibility.
|
||||
* - RE-ESTABLISHMENT: re-adding the persistent fact re-asserts its
|
||||
* precedence immediately (no stale partial-only state).
|
||||
* - LAYER PRECEDENCE: two partial facts for the same triple at
|
||||
* different layers resolve to the higher-trust layer.
