|
||||
|
||||
## Key Testing Principles
|
||||
|
||||
### Kenya Rule Compliance
|
||||
Every feature includes performance scenarios:
|
||||
- Memory usage < 10MB
|
||||
- Execution time benchmarks for O(|V|×|E|) algorithms
|
||||
- Bandwidth limits for gossip
|
||||
|
||||
### Security Coverage
|
||||
- Betrayal detection (negative cycles)
|
||||
- Eclipse attack resilience
|
||||
- Replay protection (entropy stamps)
|
||||
- Signature verification
|
||||
|
||||
### Integration Points
|
||||
- PoP (Proof-of-Path) verification
|
||||
- Reputation decay over time
|
||||
- RiskGraph → CompactTrustGraph mapping
|
||||

|
||||
|
||||
## Running Tests
|
||||
|
||||
### Future: Zig Implementation
|
||||
```bash
|
||||
# Run all QVL tests
|
||||
zig build test-qvl
|
||||
|
||||
# Run specific feature
|
||||
zig build test -- --feature betrayal_detection
|
||||
|
||||
# Run with coverage
|
||||
zig build test-qvl-coverage
|
||||
```
|
||||
|
||||
### Current: Documentation Phase
|
||||
These features serve as:
|
||||
1. **Specification** — What QVL should do
|
||||
2. **Acceptance Criteria** — When we're done
|
||||
3. **Documentation** — How it works
|
||||
4. **Test Template** — For Zig implementation
|
||||
|
||||

|
||||
|
||||
## GQL Integration (Future)
|
||||
|
||||
When GQL Parser is implemented:
|
||||
```gherkin
|
||||
Scenario: GQL query for trust path
|
||||
When I execute GQL "MATCH (a:Identity)-[t:TRUST*1..3]->(b:Identity) WHERE a.did = 'did:alice' RETURN b"
|
||||
Then I should receive reachable nodes within 3 hops
|
||||
```
|
||||

Feature: Loopy Belief Propagation
|
||||
As a Libertaria node under eclipse attack
|
||||
I need Bayesian inference over the trust DAG
|
||||
So that I can estimate trust under uncertainty and detect anomalies
|
||||
|
||||
Background:
|
||||
Given a trust graph with partial visibility:
|
||||
| from | to | observed | prior_trust |
|
||||
| alice | bob | true | 0.6 |
|
||||
| bob | charlie | false | unknown |
|
||||
| alice | dave | true | 0.8 |
|
||||
|
||||
# Belief Propagation Core
|
||||
Scenario: Propagate beliefs through observed edges
|
||||
When I run Belief Propagation from "alice"
|
||||
Then the belief for "bob" should converge to ~0.6
|
||||
And the belief for "alice" should be 1.0 (self-trust)
|
||||
|
||||
Scenario: Infer unobserved edge from network structure
|
||||
Given "alice" trusts "bob" (0.6)
|
||||
And "bob" is likely to trust "charlie" (transitivity)
|
||||
When I run BP with max_iterations 100
|
||||
Then the belief for "charlie" should be > 0.5
|
||||
And < 0.6 (less certain than direct observation)
|
||||
|
||||
Scenario: Convergence detection
|
||||
When I run BP with epsilon 1e-6
|
||||
Then the algorithm should stop when max belief delta < epsilon
|
||||
And the converged flag should be true
|
||||
And iterations should be < max_iterations
|
||||
|
||||
Scenario: Non-convergence handling
|
||||
Given a graph with oscillating beliefs (bipartite structure)
|
||||
When I run BP with damping 0.5
|
||||
Then the algorithm should force convergence via damping
|
||||
Or report non-convergence after max_iterations
|
||||
|
||||
# Anomaly Scoring
|
||||
Scenario: Anomaly from BP divergence
|
||||
Given a node with belief 0.9 from one path
|
||||
And belief 0.1 from another path (conflict)
|
||||
When BP converges
|
||||
Then the anomaly score should be high (> 0.7)
|
||||
And the reason should be "bp_divergence"
|
||||
|
||||
Scenario: Eclipse attack detection
|
||||
Given an adversary controls 90% of observed edges to "victim"
|
||||
And the adversary reports uniformly positive trust
|
||||
When BP runs with honest nodes as priors
|
||||
Then the victim's belief should remain moderate (not extreme)
|
||||
And the coverage metric should indicate "potential_eclipse"
|
||||
|
||||
# Damping and Stability
|
||||
Scenario Outline: Damping factor effects
|
||||
Given a graph prone to oscillation
|
||||
When I run BP with damping <damping>
|
||||
Then convergence should occur in <iterations> iterations
|
||||
|
||||
Examples:
|
||||
| damping | iterations |
|
||||
| 0.0 | > 100 |
|
||||
| 0.5 | ~50 |
|
||||
| 0.9 | ~20 |
|
||||
|
||||
# Integration with Bellman-Ford
|
||||
Scenario: BP complements negative cycle detection
|
||||
Given a graph with a near-negative-cycle (ambiguous betrayal)
|
||||
When Bellman-Ford is inconclusive
|
||||
And BP reports high anomaly for involved nodes
|
||||
Then the combined evidence suggests investigation
|
||||
|
||||
# Performance Constraints
|
||||
Scenario: BP complexity
|
||||
Given a graph with 1000 nodes and 5000 edges
|
||||
When I run BP with epsilon 1e-6
|
||||
Then convergence should occur within 50 iterations
|
||||
And total time should be < 100ms
|
||||
And memory should be O(|V| + |E|)

Feature: Bellman-Ford Betrayal Detection
|
||||
As a Libertaria security node
|
||||
I need to detect negative cycles in the trust graph
|
||||
So that I can identify collusion rings and betrayal patterns
|
||||
|
||||
Background:
|
||||
Given a QVL database with the following trust edges:
|
||||
| from | to | level | risk |
|
||||
| alice | bob | 3 | -0.3 |
|
||||
| bob | charlie | 3 | -0.3 |
|
||||
| charlie | alice | -7 | 1.0 |
|
||||
|
||||
# Negative Cycle Detection
|
||||
Scenario: Detect simple negative cycle (betrayal ring)
|
||||
When I run Bellman-Ford from "alice"
|
||||
Then a negative cycle should be detected
|
||||
And the cycle should contain nodes: "alice", "bob", "charlie"
|
||||
And the anomaly score should be 1.0 (critical)
|
||||
|
||||
Scenario: No cycle in legitimate trust chain
|
||||
Given a QVL database with the following trust edges:
|
||||
| from | to | level | risk |
|
||||
| alice | bob | 3 | -0.3 |
|
||||
| bob | charlie | 3 | -0.3 |
|
||||
| charlie | dave | 3 | -0.3 |
|
||||
When I run Bellman-Ford from "alice"
|
||||
Then no negative cycle should be detected
|
||||
And the anomaly score should be 0.0
|
||||
|
||||
Scenario: Multiple betrayal cycles
|
||||
Given a QVL database with the following trust edges:
|
||||
| from | to | level | risk |
|
||||
| alice | bob | -5 | 0.5 |
|
||||
| bob | alice | -5 | 0.5 |
|
||||
| charlie | dave | -5 | 0.5 |
|
||||
| dave | charlie | -5 | 0.5 |
|
||||
When I run Bellman-Ford from "alice"
|
||||
Then 2 negative cycles should be detected
|
||||
And cycle 1 should contain: "alice", "bob"
|
||||
And cycle 2 should contain: "charlie", "dave"
|
||||
|
||||
# Evidence Generation
|
||||
Scenario: Generate cryptographic evidence of betrayal
|
||||
Given a negative cycle has been detected:
|
||||
| node | risk |
|
||||
| alice | -0.3 |
|
||||
| bob | -0.3 |
|
||||
| charlie | 1.0 |
|
||||
When I generate evidence for the cycle
|
||||
Then the evidence should be a byte array
|
||||
And the evidence version should be 0x01
|
||||
And the evidence should contain all 3 node IDs
|
||||
And the evidence should contain all risk scores
|
||||
And the evidence hash should be deterministic
|
||||
|
||||
Scenario: Evidence serialization format
|
||||
When I generate evidence for a cycle with nodes "alice", "bob"
|
||||
Then the evidence format should be:
|
||||
"""
|
||||
version(1 byte) + cycle_len(4 bytes) +
|
||||
[node_id(4 bytes) + risk(8 bytes)]...
|
||||
"""

# Performance Constraints (Kenya Rule)
|
||||
Scenario Outline: Bellman-Ford complexity with graph size
|
||||
Given a graph with <nodes> nodes and <edges> edges
|
||||
When I run Bellman-Ford
|
||||
Then the execution time should be less than <time_ms> milliseconds
|
||||
And the memory usage should be less than 10MB
|
||||
|
||||
Examples:
|
||||
| nodes | edges | time_ms |
|
||||
| 100 | 500 | 50 |
|
||||
| 1000 | 5000 | 500 |
|
||||
| 10000 | 50000 | 5000 |
|
||||
|
||||
# Early Exit Optimization
|
||||
Scenario: Early exit when no improvements possible
|
||||
Given a graph where no edges can be relaxed after pass 3
|
||||
When I run Bellman-Ford
|
||||
Then the algorithm should exit after pass 3
|
||||
And not run all |V|-1 passes

Feature: Aleph-Style Gossip Protocol
|
||||
As a Libertaria node in a partitioned network
|
||||
I need probabilistic message flooding with DAG references
|
||||
So that trust signals propagate despite intermittent connectivity
|
||||
|
||||
Background:
|
||||
Given a network of 5 nodes: alpha, beta, gamma, delta, epsilon
|
||||
And each node has initialized gossip state
|
||||
And the erasure tolerance parameter k = 3
|
||||
|
||||
# Gossip Message Structure
|
||||
Scenario: Create gossip message with DAG references
|
||||
Given node "alpha" has received messages with IDs [100, 101, 102]
|
||||
When "alpha" creates a gossip message of type "trust_vouch"
|
||||
Then the message should reference k=3 prior messages
|
||||
And the message ID should be computed from (sender + entropy + payload)
|
||||
And the message should have an entropy stamp
|
||||
|
||||
Scenario: Gossip message types
|
||||
When I create a gossip message of type "<type>"
|
||||
Then the message type code should be <code>
|
||||
|
||||
Examples:
|
||||
| type | code |
|
||||
| trust_vouch | 0 |
|
||||
| trust_revoke | 1 |
|
||||
| reputation_update | 2 |
|
||||
| heartbeat | 3 |
|
||||
|
||||
# Probabilistic Flooding
|
||||
Scenario: Message propagation probability
|
||||
Given node "alpha" broadcasts a gossip message
|
||||
When the message reaches "beta"
|
||||
Then "beta" should forward with probability p = 0.7
|
||||
And the expected coverage after 3 hops should be > 80%
|
||||
|
||||
Scenario: Duplicate detection via message ID
|
||||
Given node "beta" has seen message ID 12345
|
||||
When "beta" receives message ID 12345 again
|
||||
Then "beta" should not forward the duplicate
|
||||
And "beta" should update the seen timestamp
|
||||
|
||||
# DAG Structure and Partition Detection
|
||||
Scenario: Build gossip DAG
|
||||
Given the following gossip sequence:
|
||||
| sender | refs |
|
||||
| alpha | [] |
|
||||
| beta | [alpha:1] |
|
||||
| gamma | [alpha:1, beta:1] |
|
||||
Then the DAG should have 3 nodes
|
||||
And "gamma" should have 2 incoming edges
|
||||
And the DAG depth should be 2
|
||||
|
||||
Scenario: Detect network partition via coverage
|
||||
Given the network has partitioned into [alpha, beta] and [gamma, delta]
|
||||
When "alpha" tracks gossip coverage
|
||||
And messages from "alpha" fail to reach "gamma" for 60 seconds
|
||||
Then "alpha" should report "low_coverage" anomaly
|
||||
And the anomaly score should be > 0.7
|
||||
|
||||
Scenario: Heal partition upon reconnection
|
||||
Given a partition exists between [alpha, beta] and [gamma]
|
||||
When the partition heals and "beta" reconnects to "gamma"
|
||||
Then "beta" should sync missing gossip messages
|
||||
And "gamma" should acknowledge receipt
|
||||
And the coverage anomaly should resolve
|
||||
|
||||
# Entropy and Replay Protection
|
||||
Scenario: Entropy stamp ordering
|
||||
Given message A with entropy 1000
|
||||
And message B with entropy 2000
|
||||
Then message B is newer than message A
|
||||
And a node should reject messages with entropy < last_seen - window
|
||||
|
||||
Scenario: Replay attack prevention
|
||||
Given node "alpha" has entropy window [1000, 2000]
|
||||
When "alpha" receives a message with entropy 500
|
||||
Then the message should be rejected as "stale"
|
||||
And "alpha" should not forward it
|
||||
|
||||
# Erasure Tolerance
|
||||
Scenario: Message loss tolerance
|
||||
Given a gossip DAG with k=3 references per message
|
||||
When 30% of messages are lost randomly
|
||||
Then the DAG should remain connected with > 95% probability
|
||||
And reconstruction should be possible via redundant paths
|
||||
|
||||
# Performance (Kenya Rule)
|
||||
Scenario: Gossip overhead
|
||||
Given a network with 1000 nodes
|
||||
When each node sends 1 message per minute
|
||||
Then the bandwidth per node should be < 10 KB/minute
|
||||
And the memory for gossip state should be < 1 MB

Feature: A* Trust Pathfinding
|
||||
As a Libertaria agent
|
||||
I need to find reputation-guided paths through the trust graph
|
||||
So that I can verify trust relationships efficiently
|
||||
|
||||
Background:
|
||||
Given a QVL database with the following trust topology:
|
||||
| from | to | level | risk | reputation |
|
||||
| alice | bob | 3 | -0.3 | 0.8 |
|
||||
| bob | charlie | 3 | -0.3 | 0.7 |
|
||||
| alice | dave | 3 | -0.3 | 0.9 |
|
||||
| dave | charlie | 3 | -0.3 | 0.6 |
|
||||
| bob | eve | 3 | -0.3 | 0.2 |
|
||||
|
||||
# Basic Pathfinding
|
||||
Scenario: Find shortest trust path
|
||||
When I search for a path from "alice" to "charlie"
|
||||
Then the path should be: "alice" → "bob" → "charlie"
|
||||
And the total cost should be approximately 0.6
|
||||
|
||||
Scenario: No path exists
|
||||
When I search for a path from "alice" to "frank"
|
||||
Then the path should be null
|
||||
And the result should indicate "no path found"
|
||||
|
||||
Scenario: Direct path preferred over indirect
|
||||
Given "alice" has direct trust level 7 to "charlie"
|
||||
When I search for a path from "alice" to "charlie"
|
||||
Then the path should be: "alice" → "charlie"
|
||||
And the path length should be 1
|
||||
|
||||
# Reputation-Guided Pathfinding
|
||||
Scenario: Reputation heuristic avoids low-reputation nodes
|
||||
When I search for a path from "alice" to "eve"
|
||||
Then the path should be: "alice" → "bob" → "eve"
|
||||
And the algorithm should penalize "bob" for low reputation (0.2)
|
||||
|
||||
Scenario: Zero heuristic degrades to Dijkstra
|
||||
When I search with zero heuristic from "alice" to "charlie"
|
||||
Then the result should be optimal (guaranteed shortest path)
|
||||
But the search should expand more nodes than with reputation heuristic
|
||||
|
||||
# Path Verification
|
||||
Scenario: Verify constructed path
|
||||
Given a path: "alice" → "bob" → "charlie"
|
||||
When I verify the path against the graph
|
||||
Then each edge in the path should exist
|
||||
And no edge should be expired
|
||||
And the path verification should succeed
|
||||
|
||||
Scenario: Verify path with expired edge
|
||||
Given a path: "alice" → "bob" → "charlie"
|
||||
And the edge "bob" → "charlie" has expired
|
||||
When I verify the path
|
||||
Then the verification should fail
|
||||
And the error should indicate "expired edge at hop 2"
|
||||
|
||||
# Proof-of-Path
|
||||
Scenario: Generate Proof-of-Path bundle
|
||||
Given a valid path: "alice" → "bob" → "charlie"
|
||||
When I generate a Proof-of-Path
|
||||
Then the PoP should contain all edge signatures
|
||||
And the PoP should be verifiable by any node
|
||||
And the PoP should have a timestamp and entropy stamp
|
||||
|
||||
Scenario: Verify Proof-of-Path
|
||||
Given a Proof-of-Path from "alice" to "charlie"
|
||||
When any node verifies the PoP
|
||||
Then the verification should succeed if all signatures are valid
|
||||
And the verification should fail if any signature is invalid
|
||||
|
||||
# Path Constraints
|
||||
Scenario: Maximum path depth
|
||||
When I search for a path with max_depth 2 from "alice" to "charlie"
|
||||
And the shortest path requires 3 hops
|
||||
Then the search should return null
|
||||
And indicate "max depth exceeded"
|
||||
|
||||
Scenario: Minimum trust threshold
|
||||
When I search for a path with minimum_trust_level 5
|
||||
And all edges have level 3
|
||||
Then no path should be found
|
||||
And the result should indicate "trust threshold not met"

I need to verify trust paths cryptographically
|
||||
And maintain reputation scores based on verification history
|
||||
So that trust decay reflects actual behavior
|
||||
|
||||
Background:
|
||||
Given a QVL database with established trust edges
|
||||
And a reputation map for all nodes
|
||||
|
||||
# Reputation Scoring
|
||||
Scenario: Initial neutral reputation
|
||||
Given a new node "frank" joins the network
|
||||
Then "frank"'s reputation score should be 0.5 (neutral)
|
||||
And total_checks should be 0
|
||||
|
||||
Scenario: Reputation increases with successful verification
|
||||
When node "alice" sends a PoP that verifies successfully
|
||||
Then "alice"'s reputation should increase
|
||||
And the increase should be damped (not immediate 1.0)
|
||||
And successful_checks should increment
|
||||
|
||||
Scenario: Reputation decreases with failed verification
|
||||
When node "bob" sends a PoP that fails verification
|
||||
Then "bob"'s reputation should decrease
|
||||
And the decrease should be faster than increases (asymmetry)
|
||||
And total_checks should increment
|
||||
|
||||
Scenario: Bayesian reputation update formula
|
||||
Given "charlie" has reputation 0.6 after 10 checks
|
||||
When a new verification succeeds
|
||||
Then the update should be: score = 0.7*0.6 + 0.3*(10/11)
|
||||
And the new score should be approximately 0.645
|
||||
|
||||
# Reputation Decay
|
||||
Scenario: Time-based reputation decay
|
||||
Given "alice" has reputation 0.8 from verification at time T
|
||||
When half_life time passes without new verification
|
||||
Then "alice"'s reputation should decay to ~0.4
|
||||
When another half_life passes
|
||||
Then reputation should decay to ~0.2
|
||||
|
||||
Scenario: Decay stops at minimum threshold
|
||||
Given "bob" has reputation 0.1 (low but not zero)
|
||||
When significant time passes
|
||||
Then "bob"'s reputation should not go below 0.05 (floor)
|
||||
|
||||
# PoP Verification Flow
|
||||
Scenario: Successful PoP verification
|
||||
Given a valid Proof-of-Path from "alice" to "charlie"
|
||||
When I verify against the expected receiver and sender
|
||||
Then the verdict should be "valid"
|
||||
And "alice"'s reputation should increase
|
||||
And the verification should be logged with entropy stamp
|
||||
|
||||
Scenario: Broken link in PoP
|
||||
Given a PoP with an edge that no longer exists
|
||||
When I verify the PoP
|
||||
Then the verdict should be "broken_link"
|
||||
And the specific broken edge should be identified
|
||||
And "alice"'s reputation should decrease
|
||||
|
||||
Scenario: Expired edge in PoP
|
||||
Given a PoP containing an expired trust edge
|
||||
When I verify the PoP
|
||||
Then the verdict should be "expired"
|
||||
And the expiration timestamp should be reported
|
||||
|
||||
Scenario: Invalid signature in PoP
|
||||
Given a PoP with a tampered signature
|
||||
When I verify the PoP
|
||||
Then the verdict should be "invalid_signature"
|
||||
And "alice"'s reputation should decrease significantly
|
||||
|
||||
# A* Heuristic Integration
|
||||
Scenario: Reputation-guided pathfinding
|
||||
Given "alice" has reputation 0.9
|
||||
And "bob" has reputation 0.3
|
||||
When searching for a path through either node
|
||||
Then the algorithm should prefer "alice" (higher reputation)
|
||||
And the path cost through "alice" should be lower
|
||||
|
||||
Scenario: Admissible heuristic guarantee
|
||||
Given any reputation configuration
|
||||
When using reputationHeuristic for A*
|
||||
Then the heuristic should never overestimate true cost
|
||||
And A* optimality should be preserved
|
||||
|
||||
# Low Reputation Handling
|
||||
Scenario: Identify low-reputation nodes
|
||||
Given nodes with reputations:
|
||||
| node | reputation |
|
||||
| alice | 0.9 |
|
||||
| bob | 0.2 |
|
||||
| charlie | 0.1 |
|
||||
When I query for nodes below threshold 0.3
|
||||
Then I should receive ["bob", "charlie"]
|
||||
|
||||
Scenario: Quarantine trigger
|
||||
Given "mallory" has reputation < 0.2 after 10+ checks
|
||||
When the low-reputation threshold is 0.2
|
||||
Then "mallory" should be flagged for quarantine review
|
||||
And future PoPs from "mallory" should be extra scrutinized
|
||||
|
||||
# Bulk Operations
|
||||
Scenario: Decay all reputations periodically
|
||||
Given 1000 nodes with various last_verified times
|
||||
When the daily decay job runs
|
||||
Then all reputations should be updated based on time since last verification
|
||||
And the operation should complete in < 100ms
|
||||
|
||||
Scenario: Populate RiskGraph from reputation
|
||||
Given a CompactTrustGraph with raw trust levels
|
||||
And a ReputationMap with scores
|
||||
When I populate the RiskGraph
|
||||
Then each edge risk should be calculated as (1 - reputation)
|
||||
And the RiskGraph should be ready for Bellman-Ford

Feature: QVL Trust Graph Core
|
||||
As a Libertaria node operator
|
||||
I need to manage trust relationships in a graph
|
||||
So that I can establish verifiable trust paths between agents
|
||||
|
||||
Background:
|
||||
Given a new QVL database is initialized
|
||||
And the following DIDs are registered:
|
||||
| did | alias |
|
||||
| did:alice:123 | alice |
|
||||
| did:bob:456 | bob |
|
||||
| did:charlie:789 | charlie |
|
||||
|
||||
# RiskGraph Basic Operations
|
||||
Scenario: Add trust edge between two nodes
|
||||
When "alice" grants trust level 3 to "bob"
|
||||
Then the graph should contain an edge from "alice" to "bob"
|
||||
And the edge should have trust level 3
|
||||
And "bob" should be in "alice"'s outgoing neighbors
|
||||
|
||||
Scenario: Remove trust edge
|
||||
Given "alice" has granted trust to "bob"
|
||||
When "alice" revokes trust from "bob"
|
||||
Then the edge from "alice" to "bob" should not exist
|
||||
And "bob" should not be in "alice"'s outgoing neighbors
|
||||
|
||||
Scenario: Query incoming trust edges
|
||||
Given "alice" has granted trust to "charlie"
|
||||
And "bob" has granted trust to "charlie"
|
||||
When I query incoming edges for "charlie"
|
||||
Then I should receive 2 edges
|
||||
And the edges should be from "alice" and "bob"
|
||||
|
||||
Scenario: Trust edge with TTL expiration
|
||||
When "alice" grants trust level 5 to "bob" with TTL 86400 seconds
|
||||
Then the edge should have an expiration timestamp
|
||||
And the edge should be valid immediately
|
||||
When 86401 seconds pass
|
||||
Then the edge should be expired
|
||||
And querying the edge should return null
|
||||
|
||||
# RiskEdge Properties
|
||||
Scenario Outline: Risk score calculation from trust level
|
||||
When "alice" grants trust level <level> to "bob"
|
||||
Then the risk score should be <risk>
|
||||
|
||||
Examples:
|
||||
| level | risk |
|
||||
| 7 | -1.0 |
|
||||
| 3 | -0.3 |
|
||||
| 0 | 0.0 |
|
||||
| -3 | 0.3 |
|
||||
| -7 | 1.0 |
|
||||
|
||||
Scenario: Edge metadata includes entropy stamp
|
||||
When "alice" grants trust to "bob" at entropy 1234567890
|
||||
Then the edge should have entropy stamp 1234567890
|
||||
And the edge should have a unique nonce
|
||||
|
||||
Scenario: Betrayal edge detection
|
||||
When "alice" grants trust level -7 to "bob"
|
||||
Then the edge should be marked as betrayal
|
||||
And the risk score should be positive

|
||||
## Quick Start
|
||||
|
||||
### 1. Sovereign Identity
|
||||
|
||||
```janus
|
||||
import libertaria.{identity}
|
||||
|
||||
// Create a new sovereign identity
|
||||
let id = identity.create()
|
||||
|
||||
// Sign a message
|
||||
let msg = bytes.from_string("Hello Sovereigns!")
|
||||
let sig = identity.sign(id, msg)
|
||||
|
||||
// Verify signature
|
||||
assert identity.verify(id, msg, sig)
|
||||
|
||||
// Rotate identity (new keys, linked provenance)
|
||||
let (new_id, old_id) = identity.rotate(id)
|
||||
|
||||
// Burn identity (cryptographic deletion)
|
||||
let burned = identity.burn(id)
|
||||
```
|
||||
|
||||
### 2. Trust Graph (QVL)
|
||||
|
||||
```janus
|
||||
import libertaria.{qvl}
|
||||
|
||||
// Create hybrid graph (persistent + in-memory)
|
||||
let graph = qvl.HybridGraph.init(&persistent, allocator)
|
||||
|
||||
// Add trust edges
|
||||
graph.addEdge(.{
|
||||
from = alice,
|
||||
to = bob,
|
||||
risk = -0.3, // Negative = trust
|
||||
level = 3, // Trust level 1-7
|
||||
timestamp = now(),
|
||||
expires_at = now() + duration.days(30)
|
||||
})
|
||||
|
||||
// Detect betrayal rings (negative cycles)
|
||||
let result = try graph.detectBetrayal(alice)
|
||||
if result.betrayal_cycles.items.len > 0 {
|
||||
// Handle betrayal
|
||||
}
|
||||
|
||||
// Find trust path
|
||||
let path = try graph.findTrustPath(alice, charlie,
|
||||
heuristic = qvl.reputationHeuristic,
|
||||
heuristic_ctx = &rep_map)
|
||||
```
|
||||
|
||||
### 3. GQL (Graph Query Language)
|
||||
|
||||
```janus
|
||||
import libertaria.{gql}
|
||||
|
||||
// Parse GQL query
|
||||
let query_str = "MATCH (n:Identity)-[t:TRUST]->(m) WHERE n.did = 'alice' RETURN m"
|
||||
let query = try gql.parse(allocator, query_str)
|
||||
defer query.deinit()
|
||||
|
||||
// Transpile to Zig code
|
||||
let zig_code = try gql.generateZig(allocator, query)
|
||||
defer allocator.free(zig_code)
|
||||
|
||||
// Generated code looks like:
|
||||
// pub fn execute(graph: *qvl.HybridGraph) !void {
|
||||
// // MATCH statement
|
||||
// // Traverse from n
|
||||
// var t = try graph.getOutgoing(n);
|
||||
// // Filter by type: TRUST
|
||||
// var m = t.to;
|
||||
// // WHERE n.did == "alice"
|
||||
// // RETURN statement
|
||||
// var results = std.ArrayList(Result).init(allocator);
|
||||
// defer results.deinit();
|
||||
// try results.append(m);
|
||||
// }
|
||||
```

## GQL Syntax
|
||||
|
||||
### MATCH — Pattern Matching
|
||||
|
||||
```gql
|
||||
-- Simple node
|
||||
MATCH (n:Identity)
|
||||
|
||||
-- Node with properties
|
||||
MATCH (n:Identity {did: 'alice', active: true})
|
||||
|
||||
-- One-hop traversal
|
||||
MATCH (a)-[t:TRUST]->(b)
|
||||
|
||||
-- Variable-length path
|
||||
MATCH (a)-[t:TRUST*1..3]->(b)
|
||||
|
||||
-- With WHERE clause
|
||||
MATCH (n:Identity)-[t:TRUST]->(m)
|
||||
WHERE n.did = 'alice' AND t.level >= 3
|
||||
RETURN m
|
||||
```
|
||||
|
||||
### CREATE — Insert Data
|
||||
|
||||
```gql
|
||||
-- Create node
|
||||
CREATE (n:Identity {did: 'alice'})
|
||||
|
||||
-- Create edge
|
||||
CREATE (a)-[t:TRUST {level: 3}]->(b)
|
||||
|
||||
-- Create pattern
|
||||
CREATE (a:Identity)-[t:TRUST]->(b:Identity)
|
||||
```
|
||||
|
||||
### DELETE — Remove Data
|
||||
|
||||
```gql
|
||||
-- Delete nodes
|
||||
MATCH (n:Identity)
|
||||
WHERE n.did = 'compromised'
|
||||
DELETE n
|
||||
```
|
||||
|
||||
### RETURN — Project Results
|
||||
|
||||
```gql
|
||||
-- Return variable
|
||||
MATCH (n) RETURN n
|
||||
|
||||
-- Return multiple
|
||||
MATCH (a)-[t]->(b) RETURN a, t, b
|
||||
|
||||
-- With alias
|
||||
MATCH (n) RETURN n.did AS identity
|
||||
|
||||
-- Aggregations (planned)
|
||||
MATCH (n) RETURN count(n) AS total
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Design Principles
|
||||
|
||||
### 1. Exit is Voice
|
||||
|
||||
Agents can leave, taking their data cryptographically:
|
||||
|
||||
```janus
|
||||
// Burn identity
|
||||
let burned = identity.burn(my_id)
|
||||
// After burn: no new signatures possible
|
||||
// Verification of historical signatures still works
|
||||
```
|
||||
|
||||
### 2. Profit = Honesty
|
||||
|
||||
Economic stakes align incentives:
|
||||
|
||||
- **Posting** requires $SCRAP burn
|
||||
- **Identity** requires $STASIS bond
|
||||
- **Reputation** decays without verification
|
||||
|
||||
### 3. Code is Law
|
||||
|
||||
No central moderation, only protocol rules:
|
||||
|
||||
- **Betrayal detection** via Bellman-Ford (mathematical, not subjective)
|
||||
- **Path verification** via cryptographic proofs
|
||||
- **Reputation** via Bayesian updates
|
||||
|
||||
### 4. Kenya Compliance
|
||||
|
||||
Resource-constrained environments:
|
||||
|
||||
- **Binary size:** <200KB for L1
|
||||
- **Memory:** <10MB for graph operations
|
||||
- **Storage:** Single-file embedded (libmdbx)
|
||||
- **No cloud calls:** Fully offline-capable
|
||||

|
||||
//!
|
||||
//! ## Core Concepts
|
||||
//!
|

//! - **Session**: A sovereign state machine representing trust relationship
|
||||
//! - **Handshake**: PQxdh-based mutual authentication
|

//!
|
||||
//! ## Transport
|
||||
//!
|
||||
//! This module uses QUIC and μTCP (micro-transport).
|
||||
//! WebSockets are explicitly excluded by design (ADR-001).
|
||||
//!
|
||||
//! ## Usage
|
||||
//!
|

# L2 Session Manager
|
||||
|
||||
Sovereign peer-to-peer session management for Libertaria.
|
||||
|
||||
## Overview
|
||||
|
||||
The L2 Session Manager establishes and maintains cryptographically verified sessions between Libertaria nodes. It provides:
|
||||
|
||||
- **Post-quantum security** (X25519Kyber768 hybrid)
|
||||
- **Resilient state machines** (graceful degradation, automatic recovery)
|
||||
- **Seamless key rotation** (no message loss during rotation)
|
||||
- **Multi-transport support** (QUIC primary, μTCP fallback)
|
||||
|
||||
## Why No WebSockets
|
||||
|
||||
This module explicitly excludes WebSockets (see ADR-001). We use:
|
||||
|
||||
| Transport | Use Case | Advantages |
|
||||
|-----------|----------|------------|
|
||||
| **QUIC** | Primary transport | 0-RTT, built-in TLS, multiplexing |
|
||||
| **μTCP** | Fallback, legacy | Micro-optimized, minimal overhead |
|
||||
| **UDP** | Discovery, broadcast | Stateless, fast probing |
|
||||
|
||||
WebSockets add HTTP overhead, proxy complexity, and fragility. Libertaria is built for the 2030s, not the 2010s.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```janus
|
||||
// Establish session
|
||||
let session = try l2_session.establish(
|
||||
peer_did: "did:morpheus:abc123",
|
||||
config: .{ ttl: 24h, heartbeat: 30s },
|
||||
ctx: ctx
|
||||
);
|
||||
|
||||
// Use session
|
||||
try session.send(message);
|
||||
let response = try session.receive(timeout: 5s);
|
||||
```
|
||||
|
||||
## State Machine
|
||||
|
||||
```
|
||||
idle → handshake_initiated → established → degraded → suspended
|
||||
↓ ↓ ↓
|
||||
failed rotating → established
|
||||
```
|
||||
|
||||
See SPEC.md for full details.
|
||||
|
||||

# SPEC-018: L2 Session Manager
|
||||
|
||||
**Status:** DRAFT
|
||||
**Version:** 0.1.0
|
||||
**Date:** 2026-02-02
|
||||
**Profile:** :service (with :core crypto primitives)
|
||||
**Supersedes:** None (New Feature)
|
||||
|
||||
---
|
||||
|
||||
## 1. Overview
|
||||
|
||||
The L2 Session Manager provides sovereign, cryptographically verified peer-to-peer session management for the Libertaria Stack. It establishes trust relationships, maintains them through network disruptions, and ensures post-quantum security through automatic key rotation.
|
||||
|
||||
### 1.1 Design Principles
|
||||
|
||||
1. **Explicit State**: Every session state is explicit, logged, and auditable
|
||||
2. **Graceful Degradation**: Sessions survive network partitions without data loss
|
||||
3. **No WebSockets**: Uses QUIC/μTCP only (see ADR-001)
|
||||
4. **Post-Quantum Security**: X25519Kyber768 hybrid key exchange
|
||||
|
||||
### 1.2 Transport Architecture
|
||||
|
||||
| Transport | Role | Protocol Details |
|
||||
|-----------|------|------------------|
|
||||
| QUIC | Primary | UDP-based, 0-RTT, TLS 1.3 built-in |
|
||||
| μTCP | Fallback | Micro-optimized TCP, minimal overhead |
|
||||
| Raw UDP | Discovery | Stateless probing, STUN-like |
|
||||
|
||||
**Rationale**: WebSockets (RFC 6455) are excluded. They add HTTP handshake overhead, require proxy support, and don't support UDP hole punching natively.
|
||||
|
||||

|
||||
|
||||
## 2. Behavioral Specification (BDD)
|
||||
|
||||
### 2.1 Session Establishment
|
||||
|
||||
```gherkin
|
||||
Feature: Session Establishment
|
||||
|
||||
Scenario: Successful establishment with new peer
|
||||
Given a discovered peer with valid DID
|
||||
When session establishment is initiated
|
||||
Then state transitions to "handshake_initiated"
|
||||
And PQxdh handshake request is sent
|
||||
When valid handshake response received
|
||||
Then state transitions to "established"
|
||||
And shared session keys are derived
|
||||
And TTL is set to 24 hours
|
||||
|
||||
Scenario: Session resumption
|
||||
Given previous session exists with unchanged prekeys
|
||||
When resumption is initiated
|
||||
Then existing key material is reused
|
||||
And state becomes "established" within 100ms
|
||||
|
||||
Scenario: Establishment timeout
|
||||
When no response within 5 seconds
|
||||
Then state transitions to "failed"
|
||||
And failure reason is "timeout"
|
||||
And retry is scheduled with exponential backoff
|
||||
|
||||
Scenario: Authentication failure
|
||||
When invalid signature received
|
||||
Then state transitions to "failed"
|
||||
And failure reason is "authentication_failed"
|
||||
And peer is quarantined for 60 seconds
|
||||
```
|
||||
|
||||
### 2.2 Session Maintenance
|
||||
|
||||
```gherkin
|
||||
Feature: Session Maintenance
|
||||
|
||||
Scenario: Heartbeat success
|
||||
When 30 seconds pass without activity
|
||||
Then heartbeat is sent
|
||||
And peer responds within 2 seconds
|
||||
And TTL is extended
|
||||
|
||||
Scenario: Single missed heartbeat
|
||||
Given peer misses 1 heartbeat
|
||||
When next heartbeat succeeds
|
||||
Then session remains "established"
|
||||
And warning is logged
|
||||
|
||||
Scenario: Session suspension
|
||||
Given peer misses 3 heartbeats
|
||||
When third timeout occurs
|
||||
Then state becomes "suspended"
|
||||
And queued messages are held
|
||||
And recovery is attempted after 60s
|
||||
|
||||
Scenario: Automatic key rotation
|
||||
Given session age reaches 24 hours
|
||||
When rotation window triggers
|
||||
Then new ephemeral keys are generated
|
||||
And re-handshake is initiated
|
||||
And no messages are lost
|
||||
```
|
||||
|
||||
### 2.3 Degradation and Recovery
|
||||
|
||||
```gherkin
|
||||
Feature: Degradation and Recovery
|
||||
|
||||
Scenario: Network partition detection
|
||||
When connectivity lost for >30s
|
||||
Then state becomes "degraded"
|
||||
And messages are queued
|
||||
And session is preserved
|
||||
|
||||
Scenario: Partition recovery
|
||||
Given session is "degraded"
|
||||
When connectivity restored
|
||||
Then re-establishment is attempted
|
||||
And queued messages are flushed
|
||||
|
||||
Scenario: Transport fallback
|
||||
Given session over QUIC
|
||||
When QUIC fails
|
||||
Then re-establishment over μTCP is attempted
|
||||
And this is transparent to upper layers
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 3. State Machine
|
||||
|
||||
### 3.1 State Definitions
|
||||
|
||||
| State | Description | Valid Transitions |
|
||||
|-------|-------------|-------------------|
|
||||
| `idle` | Initial state | `handshake_initiated`, `handshake_received` |
|
||||
| `handshake_initiated` | Awaiting response | `established`, `failed` |
|
||||
| `handshake_received` | Received request, preparing response | `established`, `failed` |
|
||||
| `established` | Active session | `degraded`, `rotating` |
|
||||
| `degraded` | Connectivity issues | `established`, `suspended` |
|
||||
| `rotating` | Key rotation in progress | `established`, `failed` |
|
||||
| `suspended` | Extended failure | `[cleanup]`, `handshake_initiated` |
|
||||
| `failed` | Terminal failure | `[cleanup]`, `handshake_initiated` (retry) |
|
||||
|
||||

## 4. Architecture Decision Records
|
||||
|
||||
### ADR-001: No WebSockets
|
||||
|
||||
**Context:** P2P systems need reliable, low-latency, firewall-traversing transport.
|
||||
|
||||
**Decision:** Exclude WebSockets. Use QUIC as primary, μTCP as fallback.
|
||||
|
||||
**Consequences:**
|
||||
- ✅ Zero HTTP overhead
|
||||
- ✅ Native UDP hole punching
|
||||
- ✅ 0-RTT connection establishment
|
||||
- ✅ Built-in TLS 1.3 (QUIC)
|
||||
- ❌ No browser compatibility (acceptable — native-first design)
|
||||
- ❌ Corporate proxy issues (mitigation: relay mode)
|
||||
|
||||
### ADR-002: State Machine Over Connection Object
|
||||
|
||||
**Context:** Traditional "connections" are ephemeral and error-prone.
|
||||
|
||||
**Decision:** Model sessions as explicit state machines with cryptographic verification.
|
||||
|
||||
**Consequences:**
|
||||
- ✅ Every transition is auditable
|
||||
- ✅ Supports offline-to-online continuity
|
||||
- ✅ Enables split-world scenarios
|
||||
- ❌ Higher cognitive load (mitigation: tooling)
|
||||
|
||||
### ADR-003: Post-Quantum Hybrid
|
||||
|
||||
**Context:** PQ crypto is slow; classical may be broken by 2035.
|
||||
|
||||
**Decision:** X25519Kyber768 hybrid key exchange.
|
||||
|
||||
**Consequences:**
|
||||
- ✅ Resistant to classical and quantum attacks
|
||||
- ✅ Hardware acceleration for X25519
|
||||
- ❌ Larger handshake packets

## 5. Interface Specification
|
||||
|
||||
### 5.1 Core Types
|
||||
|
||||
```janus
|
||||
/// Session configuration
|
||||
const SessionConfig = struct {
|
||||
/// Time-to-live before requiring re-handshake
|
||||
ttl: Duration = 24h,
|
||||
|
||||
/// Heartbeat interval
|
||||
heartbeat_interval: Duration = 30s,
|
||||
|
||||
/// Missed heartbeats before degradation
|
||||
heartbeat_tolerance: u8 = 3,
|
||||
|
||||
/// Handshake timeout
|
||||
handshake_timeout: Duration = 5s,
|
||||
|
||||
/// Key rotation window (before TTL expires)
|
||||
rotation_window: Duration = 1h,
|
||||
};
|
||||
|
||||
/// Session state enumeration
|
||||
const State = enum {
|
||||
idle,
|
||||
handshake_initiated,
|
||||
handshake_received,
|
||||
established,
|
||||
degraded,
|
||||
rotating,
|
||||
suspended,
|
||||
failed,
|
||||
};
|
||||
|
||||
/// Session error types
|
||||
const SessionError = !union {
|
||||
Timeout,
|
||||
AuthenticationFailed,
|
||||
TransportFailed,
|
||||
KeyRotationFailed,
|
||||
InvalidState,
|
||||
};
|
||||
```
|
||||
|
||||
### 5.2 Public API
|
||||
|
||||
```janus
|
||||
/// Establish new session
|
||||
func establish(
|
||||
peer_did: []const u8,
|
||||
config: SessionConfig,
|
||||
ctx: Context
|
||||
) !Session
|
||||
with ctx where ctx.has(
|
||||
.net_connect,
|
||||
.crypto_pqxdh,
|
||||
.did_resolve,
|
||||
.time
|
||||
);
|
||||
|
||||
/// Resume existing session
|
||||
func resume(
|
||||
peer_did: []const u8,
|
||||
stored: StoredSession,
|
||||
ctx: Context
|
||||
) !Session;
|
||||
|
||||
/// Accept incoming session
|
||||
func accept(
|
||||
request: HandshakeRequest,
|
||||
config: SessionConfig,
|
||||
ctx: Context
|
||||
) !Session;
|
||||
|
||||
/// Process all sessions (call in event loop)
|
||||
func tick(sessions: []Session, ctx: Context) void;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. Testing Requirements
|
||||
|
||||
### 6.1 Unit Tests
|
||||
|
||||
All Gherkin scenarios must have corresponding tests:
|
||||
|
||||
```janus
|
||||
test "Scenario-001.1: Session establishes successfully" do
|
||||
// Validates: SPEC-018 2.1 SCENARIO-1
|
||||
let session = try Session.establish(test_peer, test_config, ctx);
|
||||
assert(session.state == .handshake_initiated);
|
||||
// ... simulate response
|
||||
assert(session.state == .established);
|
||||
end
|
||||
```
|
||||
|
||||
### 6.2 Integration Tests
|
||||
|
||||
- Two-node handshake with real crypto
|
||||
- Network partition simulation
|
||||
- Transport fallback verification
|
||||
- Chaos testing (random packet loss)
|
||||
|
||||
### 6.3 Mock Interfaces
|
||||
|
||||
| Dependency | Mock Interface |
|
||||
|------------|----------------|
|
||||
| L0 Transport | `MockTransport` with latency/packet loss controls |
|
||||
| PQxdh | Deterministic test vectors |
|
||||
| Clock | Injectable `TimeSource` |
|
||||
| DID Resolver | `MockResolver` with test documents |
|
||||
|
||||
---
|
||||
|
||||
## 7. Security Considerations
|
||||
|
||||
### 7.1 Threat Model
|
||||
|
||||
| Threat | Mitigation |
|
||||
|--------|------------|
|
||||
| Man-in-the-middle | PQxdh with DID-based identity |
|
||||
| Replay attacks | Monotonic counters in heartbeats |
|
||||
| Key compromise | Automatic rotation every 24h |
|
||||
| Timing attacks | Constant-time crypto operations |
|
||||
| Denial of service | Quarantine + exponential backoff |
|
||||
|
||||
### 7.2 Cryptographic Requirements
|
||||
|
||||
- Key exchange: X25519Kyber768 (hybrid)
|
||||
- Signatures: Ed25519
|
||||
- Symmetric encryption: ChaCha20-Poly1305
|
||||
- Hashing: BLAKE3

## NCP Core Types
|
||||
|
||||
This directory contains the Nexus Context Protocol prototype implementation.
|
||||
|
||||
### Structure
|
||||
|
||||
- `src/types.nim` - Core types (CID, ContextNode, Path)
|
||||
- `src/l0_storage.nim` - File backend, CID generation (Blake3)
|
||||
- `src/l1_index.nim` - B-Tree index, path-based addressing
|
||||
- `tests/test_ncp.nim` - Unit tests
|
||||
|
||||
### Status
|
||||
|
||||
Feature 1 (Core Types): In Progress
