# Content Defense (The Shield)
|
||||
|
||||
Phase 7C introduces content defense mechanisms to detect spam, near-duplicates, and suspicious assertions before they enter the knowledge graph.
|
||||
|
||||
## Overview
|
||||
|
||||
Content Defense provides three layers of protection:
|
||||
1. **MinHash + LSH**: Near-duplicate detection with O(1) average-case lookup
|
||||
2. **Quality Scoring**: Heuristic-based spam detection (entropy, length, structure)
|
||||
3. **Quarantine Store**: Suspicious assertions held for admin review
|
||||
|
||||
Assertions that fail these checks are quarantined rather than indexed, keeping the knowledge graph clean while preserving the data for manual review.
|
||||
|
||||
## Key Concepts
|
||||
|
||||
### Quarantine Reasons
|
||||
|
||||
| Reason | Description | Trigger |
|
||||
|--------|-------------|---------|
|
||||
| `LowQuality` | Content failed quality checks | score < 0.4 |
|
||||
| `Duplicate` | Near-duplicate detected | Jaccard >= 0.9 |
|
||||
| `UntrustedHighConfidence` | Suspicious pattern | trust < 0.5 AND confidence > 0.8 |
|
||||
| `PatternMatch` | Known spam pattern | Pattern match |
|
||||
|
||||
### Quality Scoring
|
||||
|
||||
The quality score is computed from multiple signals:
|
||||
|
||||
| Component | Weight | Description |
|
||||
|-----------|--------|-------------|
|
||||
| Entropy | 40% | Shannon entropy (low = repetitive/random noise) |
|
||||
| Length | 20% | Subject/predicate length (min 3 chars each) |
|
||||
| Structure | 20% | Bonus for structured data (JSON, URLs, numbers) |
|
||||
| Trust Pattern | 20% | Penalty for untrusted + high confidence |
|
||||
|
||||
Threshold: `score < 0.4` triggers quarantine.
|
||||
|
||||
### Similarity Detection
|
||||
|
||||
MinHash + LSH parameters:
|
||||
- **MinHash k=128**: Hash functions for signature
|
||||
- **LSH 16 bands x 8 rows**: 99.96% recall at 0.9 Jaccard
|
||||
- **Bloom filter**: Fast "definitely not duplicate" pre-check
|
||||
- **Shingle size**: 3 characters (language-agnostic)
|
||||
|
||||
## HTTP API
|
||||
|
||||
### GET /v1/admin/quarantine
|
||||
|
||||
List pending quarantined assertions.
|
||||
|
||||
**Query Parameters:**
|
||||
- `limit` (optional): Maximum events to return (default: 100)
|
||||
- `include_reviewed` (optional): Include reviewed events (default: false)
|
||||
|
||||
**Response:**
|
||||
```json

|
||||
```
|
||||
|
||||
### GET /v1/admin/quarantine/{hash}
|
||||
|
||||

||||
"assertion_bytes_hex": "...",
|
||||
"assertion_bytes_base64": "...",
|
||||
"reason": "low_quality",
|
||||

|
||||
"quality": { ... },
|
||||
"timestamp": 1706918400000000000,
|
||||
"reviewed": false

|
||||
```
|
||||
|
||||
### POST /v1/admin/quarantine/{hash}/approve
|
||||
|
||||
Approve a quarantined assertion for indexing.
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"hash": "abc123...",
|
||||
"message": "Assertion approved and ready for indexing",
|
||||
"assertion_bytes_hex": "..."
|
||||
}
|
||||
```
|
||||
|
||||
### POST /v1/admin/quarantine/{hash}/reject
|
||||
|
||||

|
||||
|
||||
**Response:**
|
||||

||||
"hash": "abc123...",
|
||||
"message": "Assertion rejected"
|
||||
}
|
||||
```
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Core Types
|
||||
|
||||
**ContentQuality** (`stemedb-core/src/types/content_defense.rs`):
|
||||
- `score`: Overall quality [0.0, 1.0]
|
||||
- `entropy`: Shannon entropy (bits/char)
|
||||
- `structured`: Has structured data
|
||||
- `duplicate`: Is near-duplicate
|
||||
|
||||
**QuarantineReason** (`stemedb-core/src/types/content_defense.rs`):
|
||||
- Enum: LowQuality, Duplicate, UntrustedHighConfidence, PatternMatch
|
||||
- Method: `description()` returns human-readable string
|
||||
|
||||
**QuarantineEvent** (`stemedb-core/src/types/content_defense.rs`):
|
||||
- `hash`: BLAKE3 hash of assertion
|
||||
- `assertion_bytes`: Original serialized assertion
|
||||
- `reason`: Why quarantined
|
||||
- `quality`: Quality metrics at quarantine time
|
||||
- `reviewed`/`approved`: Admin review status
|
||||
|
||||
### Storage
|
||||
|
||||
**QuarantineStore** (`stemedb-storage/src/quarantine_store.rs`):
|
||||
- Primary key: `QUAR:{timestamp}:{hash_hex}` (time-ordered scan)
|
||||
- Index key: `QUAR_IDX:{hash_hex}` → timestamp (O(1) hash lookup)
|
||||
- Methods: `write_quarantine()`, `get_quarantine()`, `list_pending()`, `approve()`, `reject()`
|
||||
|
||||
**SimilarityIndex** (`stemedb-storage/src/similarity_index/`):
|
||||
- MinHash signature: `MH:{content_hash_hex}` → 1KB signature
|
||||
- LSH bucket: `LSH:{band:02}:{bucket_hash_hex}` → member list
|
||||
- Bloom filter: In-memory, rebuilt from `MH:` scan on startup
|
||||
|
||||
### Ingestion Integration
|
||||
|
||||
**ContentDefenseLayer** (`stemedb-ingest/src/content_defense.rs`):
|
||||
- Orchestrates Bloom filter → LSH → Quality scoring
|
||||
- Returns `QuarantineDecision::Pass` or `QuarantineDecision::Quarantine(reason)`
|
||||
- Hooks into `process_record()` after signature verification
|
||||
|
||||
### Quality Scoring
|
||||
|
||||
**ContentQualityScorer** (`stemedb-storage/src/content_defense/quality.rs`):
|
||||
- `score()` computes composite quality metric
|
||||
- Configurable thresholds via `QualityScoringConfig`
|
||||
- Default thresholds:
|
||||
- Min subject length: 3
|
||||
- Min predicate length: 3
|
||||
- Min entropy: 1.5 bits/char
|
||||
- Quality threshold: 0.4
|
||||
|
||||

v
|
||||
[Pass] ────> [Store, Index, Broadcast]
|
||||
```
|
||||
|
||||
## Security Properties
|
||||
|
||||
- **Probabilistic Dedup**: Bloom filter + LSH have false positive/negative rates
|
||||
- **No False Rejections**: Quarantine preserves data for admin review
|
||||
- **Rebuild on Startup**: Bloom filter rebuilt from persisted MinHash signatures
|
||||
- **O(1) Lookups**: LSH buckets and hash index enable constant-time checks
|
||||
- **Separate from Trust**: Content defense is orthogonal to EigenTrust
|
||||
|
||||
## Admin Workflow
|
||||
|
||||
1. Agent submits assertion
|
||||
2. Content defense flags it as duplicate
|
||||
3. Assertion stored at `QUAR:{ts}:{hash}`, NOT indexed
|
||||
4. Admin lists pending: `GET /v1/admin/quarantine`
|
||||
5. Admin reviews: `GET /v1/admin/quarantine/{hash}` (includes bytes)
|
||||
6. Admin approves: `POST .../approve` → returns bytes for indexing
|
||||
7. Or admin rejects: `POST .../reject` → remains quarantined, logged
|
||||
|
||||
## Metrics
|
||||
|
||||
| Metric | Type | Description |
|
||||
|--------|------|-------------|
|
||||
| `assertions_quarantined` | Counter | Total quarantined assertions |
|
||||
| `assertions_approved` | Counter | Admin-approved assertions |
|
||||
| `assertions_rejected` | Counter | Admin-rejected assertions |
|
||||
| `content_defense_check_duration_seconds` | Histogram | Check latency |
|
||||
| `similarity_index_size` | Gauge | Number of MinHash signatures |
|
||||
|
||||
## Future: Phase 7D (Circuit Breakers)
|
||||
|
||||
Phase 7D will build on this foundation:
|
||||
- Per-agent circuit breakers for repeated bad behavior
|
||||
- Automatic recovery with exponential backoff
|
||||
- Integration with quarantine triggers

|
||||
|
||||
## Realistic Usage Scenarios
|
||||
|
||||
### Scenario 1: New Agent Onboarding
|
||||
**Goal:** Verify graduated difficulty protects against spam bots while not blocking legitimate agents.
|
||||
|
||||
```bash
|
||||
# 1. New agent with no history should require PoW
|
||||
curl -X GET http://localhost:3000/v1/admission/status \
|
||||
-H "X-Agent-Id: 0000000000000000000000000000000000000000000000000000000000000001"
|
||||
# Expected: 200 with pow_required: true, difficulty: 16
|
||||
|
||||
# 2. Submit first assertions with PoW proof
|
||||
# Agent must solve: BLAKE3(nonce || agent_id || timestamp) has 16 leading zero bits
|
||||
# This takes ~16 seconds on average
|
||||
|
||||
# 3. After 10 assertions, difficulty drops to 1 bit (trivial)
|
||||
# 4. After 50 assertions OR trust > 0.6, PoW exempt
|
||||
```
|
||||
|
||||
**Acceptance Criteria:**
|
||||
- [ ] New agents see `pow_required: true`, `difficulty: 16`
|
||||
- [ ] HTTP 428 returned when PoW missing/invalid
|
||||
- [ ] Difficulty graduates: 16 bits (1-10) → 1 bit (11-50) → 0 (51+)
|
||||
- [ ] Trusted agents (>0.6) are exempt regardless of assertion count
|
||||
|
||||
### Scenario 2: Trust Tier Quotas
|
||||
**Goal:** Verify rate limiting scales with trust level.
|
||||
|
||||
| Tier | Trust Range | Quota Multiplier | Hourly Limit |
|
||||
|------|-------------|------------------|--------------|
|
||||
| Untrusted | 0.0-0.3 | 0.1x | 1,000/hr |
|
||||
| Limited | 0.3-0.5 | 0.5x | 5,000/hr |
|
||||
| Verified | 0.5-0.7 | 1.0x | 10,000/hr |
|
||||
| Trusted | 0.7-0.9 | 2.0x | 20,000/hr |
|
||||
| Authority | 0.9-1.0 | 10.0x | 100,000/hr |
|
||||
|
||||
**Acceptance Criteria:**
|
||||
- [ ] Quota headers present in responses (`X-RateLimit-*`)
|
||||
- [ ] Untrusted agents limited to 0.1x base quota
|
||||
- [ ] Authority agents get 10x quota
|
||||
- [ ] HTTP 429 returned when quota exceeded
|
||||
|
||||
### Scenario 3: EigenTrust Sybil Resistance
|
||||
**Goal:** Verify isolated trust rings get near-zero global trust.
|
||||
|
||||
```
|
||||
Legitimate Network: Sybil Ring:
|
||||
Seed ─────> A X ──> Y
|
||||
│ │ │ │
|
||||
v v v v
|
||||
B ──────> C Z <── W
|
||||
```
|
||||
|
||||
**Acceptance Criteria:**
|
||||
- [ ] Seed-connected agents (A, B, C) accumulate positive global trust
|
||||
- [ ] Isolated ring (X, Y, Z, W) converges to near-zero trust
|
||||
- [ ] Power iteration converges in <100 iterations (ε = 1e-4)
|
||||
- [ ] Domain-specific trust factors applied correctly
|
||||
|
||||
### Scenario 4: Content Quality Filtering
|
||||
**Goal:** Verify spam/noise detection without blocking legitimate content.
|
||||
|
||||
| Content Type | Expected Quality | Should Quarantine? |
|
||||
|--------------|------------------|-------------------|
|
||||
| Normal assertion: "Aspirin:treats:Headache" | >0.6 | No |
|
||||
| Low entropy: "aaaa:bbbb:cccc" | <0.4 | Yes |
|
||||
| Structured data with JSON | >0.7 (bonus) | No |
|
||||
| Untrusted agent + high confidence | <0.5 (penalty) | Yes |
|
||||
|
||||
**Acceptance Criteria:**
|
||||
- [ ] Shannon entropy check flags random noise (< 1.5 bits/char)
|
||||
- [ ] Minimum subject/predicate length enforced (default 3 chars)
|
||||
- [ ] Structured data (JSON, URLs, dates) gets +0.1 bonus
|
||||
- [ ] Untrusted + high confidence gets -0.5 penalty
|
||||
- [ ] Quality < 0.4 triggers quarantine
|
||||
|
||||
### Scenario 5: Quarantine Admin Workflow
|
||||
**Goal:** Verify suspicious content can be reviewed and processed.
|
||||
|
||||
```bash
|
||||
# 1. List pending quarantine events
|
||||
curl http://localhost:3000/v1/admin/quarantine?limit=20
|
||||
|
||||
# 2. Review specific event
|
||||
curl http://localhost:3000/v1/admin/quarantine/{hash}
|
||||
|
||||
# 3. Approve or reject
|
||||
curl -X POST http://localhost:3000/v1/admin/quarantine/{hash}/approve
|
||||
curl -X POST http://localhost:3000/v1/admin/quarantine/{hash}/reject
|
||||
```
|
||||
|
||||
**Acceptance Criteria:**
|
||||
- [ ] `GET /v1/admin/quarantine` lists pending events with reasons
|
||||
- [ ] `GET /v1/admin/quarantine/{hash}` returns full assertion bytes
|
||||
- [ ] `POST .../approve` moves assertion to main index
|
||||
- [ ] `POST .../reject` marks as reviewed but keeps quarantined
|
||||
- [ ] Quarantine reasons clearly indicate why flagged
|
||||
|
||||
## Integration Points to Verify
|
||||
|
||||
1. **Ingestion Pipeline Integration**
|
||||
- Content defense layer called before indexing
|
||||
- Quarantine bypasses normal index path
|
||||
- Bloom filter restored on restart
|
||||
|
||||
2. **Trust Store Interplay**
|
||||
- EigenTrust feeds into TrustTier calculation
|
||||
- Domain trust factors into Authority lens weights
|
||||
- Trust decay applies to computed scores
|
||||
|
||||
3. **API Middleware Chain**
|
||||
- AdmissionLayer checks PoW before rate limiting
|
||||
- MeterLayer applies tier-based quotas
|
||||
- Headers reflect current trust state
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **7C Incomplete:** MinHash/LSH bucketing not implemented
|
||||
- Duplicate detection uses Bloom filter only (no near-duplicate)
|
||||
- Jaccard similarity threshold (0.9) not yet enforced
|
||||
|
||||
2. **7D Not Started:** Circuit breakers pending
|
||||
- No automatic agent banning
|
||||
- No half-open recovery states
|
||||
|
||||
3. **Performance Untested:**
|
||||
- EigenTrust computation on large graphs (>10k agents)
|
||||
- Bloom filter memory at scale
|
||||
- Quarantine store scan performance
|
||||
|
||||

## Phase 5: Research Agent Loop ⬜
|
||||
## Phase 5: Research Agent Loop ✅
|
||||
|
||||
> Depends on gap data accumulating from project scans.
|
||||
> Research agent fills gaps in authoritative coverage by researching official documentation.
|
||||
|
||||
### 5.1 Gap Detection
|
||||
### 5.1 Gap Detection ✅
|
||||
|
||||
When Aphoria extracts a claim and no authoritative source exists for that concept, log it as a gap:
|
||||
| Task | Status |
|
||||
|------|--------|
|
||||
| `Gap` struct | ✅ `research/gap_detector.rs` — concept_path, topic, predicate, source info |
|
||||
| `detect_gaps()` | ✅ Compares claims against ConceptIndex, identifies missing coverage |
|
||||
| Topic normalization | ✅ Extracts last 2 path segments for cross-scheme matching |
|
||||
| Deduplication | ✅ Deduplicates gaps by topic+predicate key |
|
||||
|
||||
```
|
||||
GAP: code://rust/citadeldb/cache/redis/max_memory_policy
|
||||
No authoritative source found for redis/max_memory_policy
|
||||
Seen in 3 projects
|
||||
```
|
||||
### 5.2 Gap Storage ✅
|
||||
|
||||
### 5.2 Research Agent Trigger
|
||||
| Task | Status |
|
||||
|------|--------|
|
||||
| `GapRecord` | ✅ `research/gap_store.rs` — tracking metadata, project count, research status |
|
||||
| `GapStore` | ✅ JSON-backed persistent storage with atomic saves |
|
||||
| Project tracking | ✅ Records which projects reported each gap |
|
||||
| Research eligibility | ✅ `is_eligible_for_research()` with threshold and cooldown |
|
||||
| Gap pruning | ✅ `prune_old_gaps()` removes stale entries |
|
||||
|
||||
When a gap is seen across N projects (configurable, default 3), dispatch a research agent:
|
||||
### 5.3 Quality Validation ✅
|
||||
|
||||
1. Agent searches for authoritative documentation on `redis max_memory_policy`
|
||||
2. Finds Redis official docs
|
||||
3. Extracts normative claims: "default is `noeviction`, recommended `allkeys-lru` for cache use cases"
|
||||
4. Ingests as `vendor://redis/cache/max_memory_policy` at Tier 2
|
||||
5. Future Aphoria scans now have something to conflict against
|
||||
| Task | Status |
|
||||
|------|--------|
|
||||
| `QualityValidator` | ✅ `research/quality.rs` — validates researched claims |
|
||||
| Source attribution | ✅ Checks for authoritative domains (rfc-editor, owasp, vendor docs) |
|
||||
| Normative language | ✅ Verifies MUST/SHOULD/SHALL keywords present |
|
||||
| Vague content detection | ✅ Rejects "it depends", "typically", etc. |
|
||||
| Consistency scoring | ✅ Detects conflicting claims on same subject |
|
||||
| `QualityReport` | ✅ Detailed per-claim validation results |
|
||||
| `filter_passed()` | ✅ Returns only claims meeting quality threshold |
|
||||
|
||||
### 5.3 Community Corpus Contributions
|
||||
### 5.4 Research Execution ✅
|
||||
|
||||
Users who run Aphoria can opt in to contribute their alias mappings and acknowledgment patterns (anonymized) to a shared corpus. Common patterns propagate:
|
||||
| Task | Status |
|
||||
|------|--------|
|
||||
| `Researcher` | ✅ `research/researcher.rs` — orchestrates research pipeline |
|
||||
| `DocumentationSource` | ✅ Configurable sources with URL patterns and topics |
|
||||
| Default sources | ✅ Redis, PostgreSQL, Go, Rust, OWASP, Kafka, MongoDB |
|
||||
| Content fetching | ✅ HTTP with timeout and size limits |
|
||||
| Normative extraction | ✅ Regex-based MUST/SHOULD/SHALL extraction |
|
||||
| Section tracking | ✅ Extracts heading context for attribution |
|
||||
| Confidence scoring | ✅ Based on keyword strength, statement length, content size |
|
||||
|
||||
- "Every Rust project has this JWT pattern" → pre-built alias set for Rust JWT libraries
|
||||
- "This Redis config is always flagged and always acknowledged" → lower the default threshold for that concept
|
||||
- "This TLS pattern is always a real bug" → elevate the default threshold
|
||||
### 5.5 CLI Integration ✅
|
||||
|
||||
| Task | Status |
|
||||
|------|--------|
|
||||
| `aphoria research run` | ✅ Run research agent with configurable threshold |
|
||||
| `aphoria research status` | ✅ Show gap statistics and research progress |
|
||||
| `aphoria research gaps` | ✅ List gaps by project count |
|
||||
| `--threshold` | ✅ Minimum projects before researching (default: 3) |
|
||||
| `--strict` | ✅ Use strict quality validation |
|
||||
| `--prune` | ✅ Remove stale gaps before researching |
|
||||
| `--ready` | ✅ Show only gaps ready for research |
|
||||
|
||||
**Files:** `research/mod.rs`, `research/gap_detector.rs`, `research/gap_store.rs`, `research/quality.rs`, `research/researcher.rs`, `research/tests.rs`
|
||||
|
||||
### 5.6 Community Corpus Contributions ⬜
|
||||
|
||||
> Future: Users can opt in to contribute patterns anonymously.
|
||||
|
||||
- "Every Rust project has this JWT pattern" → pre-built alias set
|
||||
- "This Redis config is always acknowledged" → adjust default threshold
|
||||
- "This TLS pattern is always a real bug" → elevate threshold

//! In production deployments, these endpoints MUST be protected by one of:
|
||||
//!
|
||||
//! 1. **Network-level protection**: Run admin endpoints on a separate port
|
||||
//! that is only accessible from trusted networks (e.g., internal VPN).
|
||||
//!
|
||||
//! 2. **Reverse proxy authentication**: Use nginx/envoy/etc. to require
|
||||
//! authentication before requests reach these endpoints.
|
||||
//!
|
||||
//! 3. **Custom middleware**: Implement an `admin_auth` middleware layer
|
||||
//! that validates admin API keys or JWT tokens.
|
||||
//!
|
||||
//! Failing to protect these endpoints allows anyone to approve spam content
|
||||
//! or reject legitimate content from the quarantine queue.

//! agents before they consume any resources.
|

//!
|

//! # Request Flow
|

//! 3. If Open: return 503 with retry-after headers

//! Content defense layer for spam detection and quality control.

//! - Bloom filter for fast duplicate detection

//! Similarity index for near-duplicate detection using MinHash + LSH.
|
||||
//!
|
||||
//! This module provides O(1) expected-time duplicate detection for assertions:
|
||||
//!
|
||||
//! 1. **Bloom Filter**: Fast probabilistic check ("definitely not seen" or "maybe seen")
|
||||
//! 2. **MinHash**: Compact signature for estimating Jaccard similarity
|
||||
//! 3. **LSH (Locality-Sensitive Hashing)**: Efficient candidate retrieval
|
||||
//!
|
||||
//! # Usage
|
||||
//!
|
||||
//! ```ignore
|
||||
//! use stemedb_storage::{HybridStore, GenericSimilarityIndex, SimilarityIndex};
|
||||
//!
|
||||
//! let store = HybridStore::open("./data")?;
|
||||
//! let index = GenericSimilarityIndex::with_defaults(Arc::new(store));
|
||||
//!
|
||||
//! // On startup, rebuild Bloom filter from persisted data
|
||||
//! index.rebuild_bloom_filter().await?;
|
||||
//!
|
||||
//! // Check for duplicates before ingesting
|
||||
//! let result = index.check_similarity("Tesla", "has_revenue").await?;

||||
//! if result.is_duplicate {

||||
//! println!("Near-duplicate found with similarity {}", result.max_similarity);

//!
|

//! // Add new content to the index
|
||||
//! let hash = index.add("Tesla", "has_revenue", timestamp).await?;
|
||||
//! ```
|
||||
//!
|
||||
//! # Algorithm Parameters
|
||||
//!
|
||||
//! - **MinHash k=128**: 95% confidence at 0.9 Jaccard threshold
|
||||
//! - **Shingle size=3**: Character 3-grams (language-agnostic)
|
||||
//! - **LSH bands=16, rows=8**: 99.96% recall at s=0.9, good separation at s=0.8
|
||||
//! - **Bloom filter**: 1M items, 1% FPR (~1.2MB memory)
|
||||
//!
|
||||
//! # Storage Layout
|
||||
//!
|
||||
//! - MinHash signatures: `\x00MH:{content_hash_hex}`

|
||||
- Convergence: 10-20 iterations for 10K agents.

### Recently Completed
|
||||
* [x] **Phase 7C Content Defense** (The Shield): Spam and duplicate detection with quarantine workflow.
|
||||
* `SimilarityIndex` trait with MinHash (k=128) + LSH (16 bands × 8 rows) for near-duplicate detection.
|
||||
* Bloom filter pre-check for O(1) "definitely not duplicate" fast path.
|
||||
* `ContentQualityScorer` with Shannon entropy, length checks, structured data detection.
|
||||
* `QuarantineStore` with time-ordered keys + O(1) hash index for admin lookups.
|
||||
* `ContentDefenseLayer` in `stemedb-ingest` orchestrating all checks.
|
||||
* Admin API: `GET /v1/admin/quarantine`, `POST .../approve`, `POST .../reject`.
|
||||
* Triggers: quality < 0.4, 0.9+ Jaccard similarity, untrusted + confidence > 0.8.
|
||||
* [x] **Phase 6C Multi-Node Cluster** (The Mesh): Distributed cluster infrastructure.
|
||||
* `SwimMembership` with SWIM gossip protocol for node discovery and failure detection.
|
||||
* `RangeRouter` with BLAKE3 + jump hash for subject-prefix range sharding.
|
||||
* `Gateway` HTTP service with routing, health checks, and read-your-writes.
|
||||
* 82 integration tests covering membership, sharding, availability, partition tolerance.
|
||||
* [x] **Phase 7B EigenTrust** (The Shield): Sybil-resistant global trust propagation.
|
||||
* `TrustGraphStore` trait with edge CRUD, seed trust management, EigenTrust computation.
|
||||
* Power iteration: `T = (1-α)C^T*T + αP` with dangling node handling.
|
||||
* `DomainTrustStore` for per-domain expertise tracking (medicine, finance, etc.).
|
||||
* `EigenTrustAuthorityLens`: `weight = confidence × eigentrust × domain_factor`.
|
||||
* Sybil resistance: isolated rings get near-zero trust (not connected to seeds).
|
||||
* [x] **Phase 7A Admission Control** (The Shield): PoW-based spam protection for new agents.
|
||||
* `TrustTier` enum with 5 tiers, quota multipliers, PoW requirements.
|
||||
* `PowProof` struct with BLAKE3 verification, graduated difficulty (16→1→0 bits).
