# Augmentation Metadata Safety System
|
||||
|
||||
## The Problem
|
||||
Augmentations can accidentally corrupt user metadata by:
|
||||
- **Overwriting existing fields** without realizing it
|
||||
- **Colliding with other augmentations** modifying the same field
|
||||
- **Breaking data types** by changing field formats
|
||||
- **Modifying internal fields** they shouldn't touch
|
||||
|
||||
## The Solution: Metadata Contracts
|
||||
|
||||
Each augmentation declares its intentions upfront through a contract:
|
||||
|
||||
```typescript
|
||||
const contract: AugmentationMetadataContract = {
|
||||
name: 'categoryEnricher',
|
||||
version: '1.0.0',
|
||||
|
||||
// What I need to read
|
||||
reads: {
|
||||
userFields: ['title', 'description']
|
||||
},
|
||||
|
||||
// What I intend to write
|
||||
writes: {
|
||||
userFields: [
|
||||
{
|
||||
field: 'category',
|
||||
type: 'create',
|
||||
description: 'Auto-detected category',
|
||||
example: 'technology'
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Safety Levels
|
||||
|
||||
### 1. 🟢 Safe Zones (Always Allowed)
|
||||
- **Own augmentation namespace**: `_augmentations.myAug.*`
|
||||
- **Declared user fields**: Fields explicitly listed in contract
|
||||
- **Create operations**: Adding new fields that don't exist
|
||||
|
||||
### 2. 🟡 Caution Zones (Allowed with Warnings)
|
||||
- **Shared fields**: Multiple augmentations modifying same field
|
||||
- **Update operations**: Modifying existing user fields
|
||||
- **Merge operations**: Adding to existing objects/arrays
|
||||
|
||||
### 3. 🔴 Danger Zones (Blocked by Default)
|
||||
- **Undeclared fields**: Not in the contract
|
||||
- **Other augmentation namespaces**: `_augmentations.otherAug.*`
|
||||
- **Internal fields**: `_brainy.*` without permission
|
||||
|
||||
## Conflict Resolution
|
||||
|
||||
When multiple augmentations want the same field:
|
||||
|
||||
### Strategy 1: Priority-Based
|
||||
```typescript
|
||||
translator: {
|
||||
conflictResolution: {
|
||||
strategy: 'override',
|
||||
priority: 10 // Higher wins
|
||||
}
|
||||
}
|
||||
|
||||
basicEnricher: {
|
||||
conflictResolution: {
|
||||
strategy: 'override',
|
||||
priority: 5 // Lower priority
|
||||
}
|
||||
}
|
||||
// Result: translator wins
|
||||
```
|
||||
|
||||
### Strategy 2: Merge
|
||||
```typescript
|
||||
augmentation1: {
|
||||
writes: { tags: ['tech', 'web'] }
|
||||
}
|
||||
|
||||
augmentation2: {
|
||||
writes: { tags: ['framework'] }
|
||||
}
|
||||
// Result: tags = ['tech', 'web', 'framework']
|
||||
```
|
||||
|
||||
### Strategy 3: Error on Conflict
|
||||
```typescript
|
||||
conflictResolution: {
|
||||
strategy: 'error' // Fail fast
|
||||
}
|
||||
```
|
||||
|
||||
## Real-World Examples
|
||||
|
||||
### ✅ Good: Category Enricher
|
||||
```typescript
|
||||
class CategoryEnricher {
|
||||
contract = {
|
||||
writes: {
|
||||
userFields: [{
|
||||
field: 'category',
|
||||
type: 'create',
|
||||
description: 'Auto-categorization'
|
||||
}]
|
||||
}
|
||||
}
|
||||
|
||||
execute(metadata) {
|
||||
metadata.category = 'technology' // ✅ Allowed
|
||||
metadata.random = 'value' // ❌ Throws error
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### ✅ Good: Translation Service
|
||||
```typescript
|
||||
class Translator {
|
||||
contract = {
|
||||
writes: {
|
||||
userFields: [{
|
||||
field: 'translations',
|
||||
type: 'merge'
|
||||
}]
|
||||
}
|
||||
}
|
||||
|
||||
execute(metadata) {
|
||||
metadata.translations = { // ✅ Allowed
|
||||
es: 'Hola',
|
||||
fr: 'Bonjour'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### ❌ Bad: Accidental Overwrite
|
||||
```typescript
|
||||
class BadAugmentation {
|
||||
execute(metadata) {
|
||||
// No contract!
|
||||
metadata.title = 'Modified' // ❌ Could destroy user data
|
||||
metadata.deleted = true // ❌ Could conflict with internal
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Audit Trail
|
||||
|
||||
Every modification is tracked:
|
||||
|
||||
```typescript
|
||||
metadata._audit = [
|
||||
{
|
||||
augmentation: 'categoryEnricher',
|
||||
field: 'category',
|
||||
oldValue: undefined,
|
||||
newValue: 'technology',
|
||||
timestamp: 1704067200000
|
||||
},
|
||||
{
|
||||
augmentation: 'translator',
|
||||
field: 'translations.es',
|
||||
oldValue: undefined,
|
||||
newValue: 'Tecnología',
|
||||
timestamp: 1704067201000
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
## Implementation Guide
|
||||
|
||||
### Step 1: Define Your Contract
|
||||
```typescript
|
||||
export const myContract: AugmentationMetadataContract = {
|
||||
name: 'myAugmentation',
|
||||
version: '1.0.0',
|
||||
reads: {
|
||||
userFields: ['title']
|
||||
},
|
||||
writes: {
|
||||
userFields: [{
|
||||
field: 'enrichedTitle',
|
||||
type: 'create',
|
||||
description: 'Enhanced title'
|
||||
}]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2: Extend SafeAugmentation
|
||||
```typescript
|
||||
class MyAugmentation extends SafeAugmentation {
|
||||
constructor() {
|
||||
super(myContract)
|
||||
}
|
||||
|
||||
async execute(metadata: any) {
|
||||
const safe = this.getSafeMetadata(metadata)
|
||||
|
||||
// Read safely
|
||||
const title = safe.title
|
||||
|
||||
// Write safely (enforced by proxy)
|
||||
safe.enrichedTitle = title.toUpperCase()
|
||||
|
||||
return safe
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Register with Brainy
|
||||
```typescript
|
||||
brain.registerAugmentation(new MyAugmentation())
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **Prevents Accidents**: Can't overwrite fields by mistake
|
||||
2. **Clear Intentions**: Contract documents what augmentation does
|
||||
3. **Conflict Detection**: Know when augmentations clash
|
||||
4. **Audit Trail**: Track all modifications
|
||||
5. **Type Safety**: Optional type validation
|
||||
6. **Reversibility**: Can undo changes if needed
|
||||
|
||||
## Guidelines for Developers
|
||||
|
||||
### DO ✅
|
||||
- Declare ALL fields you intend to modify
|
||||
- Use your augmentation namespace for internal data
|
||||
- Provide examples in your contract
|
||||
- Handle conflicts gracefully
|
||||
- Make operations idempotent when possible
|
||||
|
||||
### DON'T ❌
|
||||
- Modify undeclared fields
|
||||
- Touch other augmentation namespaces
|
||||
- Change internal `_brainy.*` fields without permission
|
||||
- Assume exclusive access to fields
|
||||
- Delete user data without explicit permission
|
||||
|
||||
## Permission Levels
|
||||
|
||||
### Level 1: User Metadata
|
||||
- Default access for declared fields
|
||||
- Must declare intent in contract
|
||||
|
||||
### Level 2: Augmentation Namespace
|
||||
- Full access to own namespace
|
||||
- No access to other augmentation namespaces
|
||||
|
||||
### Level 3: Internal Fields
|
||||
- Requires explicit permission grant
|
||||
- Must provide reason in contract
|
||||
- Only for system augmentations
|
||||
|
||||
## Testing Your Augmentation
|
||||
|
||||
```typescript
|
||||
describe('MyAugmentation', () => {
|
||||
it('should only modify declared fields', () => {
|
||||
const metadata = { title: 'Test' }
|
||||
const aug = new MyAugmentation()
|
||||
|
||||
const result = aug.execute(metadata)
|
||||
|
||||
expect(result.enrichedTitle).toBe('TEST') // ✅
|
||||
expect(result.title).toBe('Test') // ✅ Original preserved
|
||||
expect(() => {
|
||||
result.undeclared = 'value' // ❌ Should throw
|
||||
}).toThrow()
|
||||
})
|
||||
})
|
||||
```
|
||||
|
||||
## Migration Path
|
||||
|
||||
### Phase 1: Opt-in (Current)
|
||||
- New augmentations use contracts
|
||||
- Old augmentations still work
|
||||
|
||||
### Phase 2: Warnings
|
||||
- Uncontracted modifications generate warnings
|
||||
- Developers encouraged to add contracts
|
||||
|
||||
### Phase 3: Enforcement
|
||||
- Contracts required for all augmentations
|
||||
- Safety enforcer active by default
|
||||
|
||||
## Summary
|
||||
|
||||
The contract system makes augmentations:
|
||||
- **Safer**: Can't accidentally corrupt data
|
||||
- **Clearer**: Intentions documented
|
||||
- **Composable**: Multiple augmentations can coexist
|
||||
- **Debuggable**: Full audit trail
|
||||
- **Professional**: Enterprise-ready safety

# Brainy Metadata Architecture & Namespacing
|
||||
|
||||
## The Problem 🚨
|
||||
We're mixing internal Brainy fields with user metadata, causing:
|
||||
1. **Namespace collisions** - User's `deleted` field conflicts with our soft-delete
|
||||
2. **API confusion** - Users see internal fields they shouldn't care about
|
||||
3. **Security issues** - Users could manipulate internal fields
|
||||
4. **Augmentation conflicts** - 3rd party augmentations might overwrite our fields
|
||||
|
||||
## Current Internal Fields Being Added
|
||||
|
||||
### Core System Fields
|
||||
```javascript
|
||||
metadata = {
|
||||
// USER DATA
|
||||
name: "Django",
|
||||
type: "framework",
|
||||
|
||||
// OUR INTERNAL FIELDS - COLLISION RISK!
|
||||
deleted: false, // Soft delete status
|
||||
domain: "tech", // Distributed mode domain
|
||||
domainMetadata: {}, // Domain-specific metadata
|
||||
partition: 0, // Partition for sharding
|
||||
createdAt: {...}, // GraphNoun timestamp
|
||||
updatedAt: {...}, // GraphNoun timestamp
|
||||
createdBy: {...}, // Who created this
|
||||
noun: "Concept", // NounType
|
||||
verb: "RELATES_TO", // VerbType (for relationships)
|
||||
isPlaceholder: true, // Write-only mode marker
|
||||
autoCreated: true, // Auto-created noun marker
|
||||
writeOnlyMode: true // High-speed streaming marker
|
||||
}
|
||||
```
|
||||
|
||||
### Augmentation Fields
|
||||
```javascript
|
||||
// Good - neuralImport already uses underscore prefix!
|
||||
metadata._neuralProcessed = true
|
||||
metadata._neuralConfidence = 0.95
|
||||
metadata._detectedEntities = 5
|
||||
metadata._detectedRelationships = 3
|
||||
metadata._neuralInsights = [...]
|
||||
|
||||
// Bad - direct modification
|
||||
metadata.importance = 0.8 // IntelligentVerbScoring
|
||||
```
|
||||
|
||||
## Proposed Solution: Three-Tier Metadata
|
||||
|
||||
### 1. User Metadata (Public)
|
||||
```javascript
|
||||
metadata = {
|
||||
// User's fields - completely untouched
|
||||
name: "Django",
|
||||
type: "framework",
|
||||
deleted: "2024-01-01", // User's own deleted field - no conflict!
|
||||
domain: "web", // User's domain field - no conflict!
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Internal Metadata (Protected)
|
||||
```javascript
|
||||
metadata._brainy = {
|
||||
// Core system fields - O(1) indexed
|
||||
deleted: false, // Our soft delete flag
|
||||
version: 2, // Metadata schema version
|
||||
|
||||
// Distributed mode
|
||||
partition: 0,
|
||||
distributedDomain: "tech",
|
||||
|
||||
// GraphNoun compliance
|
||||
nounType: "Concept",
|
||||
verbType: "RELATES_TO",
|
||||
createdAt: 1704067200000,
|
||||
updatedAt: 1704067200000,
|
||||
createdBy: "user:123",
|
||||
|
||||
// Performance flags
|
||||
indexed: true,
|
||||
searchable: true,
|
||||
placeholder: false,
|
||||
|
||||
// Storage optimization
|
||||
compressed: false,
|
||||
encrypted: false
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Augmentation Metadata (Semi-Protected)
|
||||
```javascript
|
||||
metadata._augmentations = {
|
||||
// Each augmentation gets its own namespace
|
||||
neuralImport: {
|
||||
processed: true,
|
||||
confidence: 0.95,
|
||||
entities: 5,
|
||||
relationships: 3
|
||||
},
|
||||
|
||||
verbScoring: {
|
||||
contextScore: 0.7,
|
||||
importance: 0.8
|
||||
},
|
||||
|
||||
// 3rd party augmentations
|
||||
customAug: {
|
||||
// Their fields isolated here
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Implementation Strategy
|
||||
|
||||
### Phase 1: Core Fields ✅
|
||||
```javascript
|
||||
// Already done with _brainy.deleted
|
||||
const BRAINY_NAMESPACE = '_brainy'
|
||||
const AUGMENTATION_NAMESPACE = '_augmentations'
|
||||
```
|
||||
|
||||
### Phase 2: Migrate All Internal Fields
|
||||
```javascript
|
||||
// Before
|
||||
metadata.domain = "tech"
|
||||
metadata.partition = 0
|
||||
|
||||
// After
|
||||
metadata._brainy.distributedDomain = "tech"
|
||||
metadata._brainy.partition = 0
|
||||
```
|
||||
|
||||
### Phase 3: Augmentation API
|
||||
```javascript
|
||||
class Augmentation {
|
||||
// Read user metadata (read-only)
|
||||
getUserMetadata(metadata) {
|
||||
const { _brainy, _augmentations, ...userMeta } = metadata
|
||||
return userMeta // Clean user data only
|
||||
}
|
||||
|
||||
// Write augmentation data (isolated)
|
||||
setAugmentationData(metadata, augName, data) {
|
||||
if (!metadata._augmentations) metadata._augmentations = {}
|
||||
metadata._augmentations[augName] = data
|
||||
}
|
||||
|
||||
// Read internal fields (for special augmentations only)
|
||||
getInternalField(metadata, field) {
|
||||
return metadata._brainy?.[field]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **No Collisions** - User can have any field names
|
||||
2. **O(1) Performance** - Internal fields still indexed
|
||||
3. **Clean API** - Users only see their data
|
||||
4. **Secure** - Internal fields protected
|
||||
5. **Extensible** - Augmentations isolated
|
||||
6. **Backward Compatible** - Migration path available
|
||||
|
||||
## Query Impact
|
||||
|
||||
### Before (Collision Risk)
|
||||
```javascript
|
||||
where: {
|
||||
deleted: false, // Ambiguous - ours or user's?
|
||||
type: "framework"
|
||||
}
|
||||
```
|
||||
|
||||
### After (Clear Separation)
|
||||
```javascript
|
||||
where: {
|
||||
'_brainy.deleted': false, // Our soft delete
|
||||
type: "framework" // User's field
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Index on `_brainy.deleted`**: O(1) hash lookup ✅
|
||||
- **Index on `_brainy.partition`**: O(1) for sharding ✅
|
||||
- **Nested field access**: Modern DBs handle this efficiently ✅
|
||||
- **Storage overhead**: ~100 bytes per item (acceptable) ✅
|
||||
|
||||
## Migration Path
|
||||
|
||||
1. **New items**: Automatically use namespaced fields
|
||||
2. **Existing items**: Lazy migration on update
|
||||
3. **Queries**: Support both formats temporarily
|
||||
4. **Deprecation**: Remove old format in v3.0
|
||||
|
||||
## Augmentation Guidelines
|
||||
|
||||
### For Core Augmentations
|
||||
- Use `_brainy.*` for system fields
|
||||
- Use `_augmentations.{name}.*` for augmentation data
|
||||
- Never modify user fields directly
|
||||
|
||||
### For 3rd Party Augmentations
|
||||
- Read user metadata via `getUserMetadata()`
|
||||
- Write only to `_augmentations.{yourName}.*`
|
||||
- Request permission for internal field access
|
||||
|
||||
## Critical Fields to Namespace
|
||||
|
||||
| Field | Current Location | New Location | Priority |
|
||||
|-------|-----------------|--------------|----------|
|
||||
| deleted | metadata.deleted | metadata._brainy.deleted | HIGH ✅ |
|
||||
| partition | metadata.partition | metadata._brainy.partition | HIGH |
|
||||
| domain | metadata.domain | metadata._brainy.distributedDomain | HIGH |
|
||||
| createdAt | metadata.createdAt | metadata._brainy.createdAt | MEDIUM |
|
||||
| updatedAt | metadata.updatedAt | metadata._brainy.updatedAt | MEDIUM |
|
||||
| noun | metadata.noun | metadata._brainy.nounType | MEDIUM |
|
||||
| verb | metadata.verb | metadata._brainy.verbType | MEDIUM |
|
||||
| isPlaceholder | metadata.isPlaceholder | metadata._brainy.placeholder | LOW |
|
||||
| autoCreated | metadata.autoCreated | metadata._brainy.autoCreated | LOW |

# Brainy Performance Analysis & Optimization
|
||||
|
||||
## Current Issues Found
|
||||
|
||||
### 1. ❌ CRITICAL: notEquals Operator is O(n)
|
||||
```javascript
|
||||
// PROBLEM: Gets ALL items to filter
|
||||
case 'notEquals':
|
||||
const allItemIds = await this.getAllIds() // O(n) - TERRIBLE!
|
||||
```
|
||||
|
||||
### 2. ❌ Soft Delete Performance
|
||||
- Every query adds `deleted: { notEquals: true }`
|
||||
- This makes EVERY query O(n) instead of O(log n)
|
||||
|
||||
### 3. ❌ exists Operator is Inefficient
|
||||
```javascript
|
||||
case 'exists':
|
||||
// Scans all cache entries - O(n)
|
||||
for (const [key, entry] of this.indexCache.entries()) {
|
||||
if (entry.field === field) {
|
||||
entry.ids.forEach(id => allIds.add(id))
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. ⚠️ Query Optimizer Not Smart Enough
|
||||
- `isSelectiveFilter()` needs to understand which filters are fast
|
||||
- Should prioritize O(1) and O(log n) operations
|
||||
|
||||
## Performance Characteristics
|
||||
|
||||
### ✅ Fast Operations (Keep These)
|
||||
| Operation | Complexity | Example |
|
||||
|-----------|-----------|---------|
|
||||
| Vector Search (HNSW) | O(log n) | `like: "query"` |
|
||||
| Exact Match | O(1) | `where: { status: "active" }` |
|
||||
| Deleted Filter (NEW) | O(1) | `where: { deleted: false }` |
|
||||
| Range Query (sorted) | O(log n) | `where: { year: { gt: 2000 } }` |
|
||||
| Graph Traversal | O(k) | `connected: { from: id }` |
|
||||
|
||||
### ❌ Slow Operations (Need Fixing)
|
||||
| Operation | Current | Should Be | Fix |
|
||||
|-----------|---------|-----------|-----|
|
||||
| notEquals | O(n) | O(1) or O(log n) | Use complement index |
|
||||
| exists | O(n) | O(1) | Maintain field existence bitmap |
|
||||
| noneOf | O(n) | O(k) | Use set operations |
|
||||
|
||||
## Optimized Architecture
|
||||
|
||||
### Solution 1: Positive Indexing for Soft Delete ✅
|
||||
```javascript
|
||||
// Instead of: deleted !== true (O(n))
|
||||
// Use: deleted === false (O(1))
|
||||
where: { deleted: false }
|
||||
|
||||
// Ensure all items have deleted field
|
||||
if (!metadata.deleted) metadata.deleted = false
|
||||
```
|
||||
|
||||
### Solution 2: Complement Indices for notEquals
|
||||
```javascript
|
||||
class MetadataIndexManager {
|
||||
// For common notEquals queries, maintain complement sets
|
||||
private complementIndices: Map<string, Set<string>> = new Map()
|
||||
|
||||
// Example: Track non-deleted items separately
|
||||
private activeItems: Set<string> = new Set()
|
||||
private deletedItems: Set<string> = new Set()
|
||||
}
|
||||
```
|
||||
|
||||
### Solution 3: Field Existence Bitmap
|
||||
```javascript
|
||||
class FieldExistenceIndex {
|
||||
private fieldBitmaps: Map<string, BitSet> = new Map()
|
||||
|
||||
hasField(id: string, field: string): boolean {
|
||||
return this.fieldBitmaps.get(field)?.has(id) ?? false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Query Execution Strategy
|
||||
|
||||
### Progressive Search (When Metadata is Selective)
|
||||
```
|
||||
1. Field Filter (O(1) or O(log n)) → Small candidate set
|
||||
2. Vector Search within candidates (O(k log k))
|
||||
3. Fusion if needed
|
||||
```
|
||||
|
||||
### Parallel Search (When Nothing is Selective)
|
||||
```
|
||||
1. Vector Search (O(log n)) → Top K results
|
||||
2. Graph Traversal (O(m)) → Connected items
|
||||
3. Field Filter (O(1)) → Metadata matches
|
||||
4. Fusion: Intersection or Union
|
||||
```
|
||||
|
||||
## Implementation Priority
|
||||
|
||||
1. **DONE** ✅ Fix soft delete to use `deleted: false`
|
||||
2. **TODO** 🔧 Optimize notEquals for common fields
|
||||
3. **TODO** 🔧 Add field existence index
|
||||
4. **TODO** 🔧 Improve query optimizer intelligence
|
||||
5. **TODO** 🔧 Add query explain mode for debugging
|
||||
|
||||
## Performance Targets
|
||||
|
||||
- Vector search: < 10ms for 1M items
|
||||
- Metadata filter: < 1ms for exact match
|
||||
- Combined query: < 20ms for complex queries
|
||||
- Soft delete overhead: < 0.1ms (O(1))

# Metadata Contract Implementation Plan
|
||||
|
||||
## New Required Interface
|
||||
|
||||
```typescript
|
||||
export interface BrainyAugmentation {
|
||||
// Identity
|
||||
name: string
|
||||
timing: 'before' | 'after' | 'around' | 'replace'
|
||||
operations: string[]
|
||||
priority: number
|
||||
|
||||
// REQUIRED metadata contract
|
||||
metadata: 'none' | 'readonly' | MetadataAccess
|
||||
|
||||
// Methods
|
||||
initialize(context: AugmentationContext): Promise<void>
|
||||
execute<T = any>(operation: string, params: any, next: () => Promise<T>): Promise<T>
|
||||
shouldExecute?(operation: string, params: any): boolean
|
||||
shutdown?(): Promise<void>
|
||||
}
|
||||
|
||||
interface MetadataAccess {
|
||||
reads?: string[] | '*' // Fields to read, or '*' for all
|
||||
writes?: string[] | '*' // Fields to write, or '*' for all
|
||||
namespace?: string // Optional: custom namespace like '_myAug'
|
||||
}
|
||||
```
|
||||
|
||||
## Augmentation Analysis & Classification
|
||||
|
||||
### Category 1: No Metadata Access ('none')
|
||||
These augmentations don't read or write metadata at all:
|
||||
|
||||
1. **CacheAugmentation** - Only caches search results
|
||||
2. **RequestDeduplicatorAugmentation** - Only deduplicates requests
|
||||
3. **ConnectionPoolAugmentation** - Only manages storage connections
|
||||
4. **StorageAugmentation** - Base storage layer, metadata handled by brainyData
|
||||
|
||||
### Category 2: Read-Only Access ('readonly')
|
||||
These augmentations read metadata but never modify it:
|
||||
|
||||
5. **WALAugmentation** - Reads metadata for logging/recovery
|
||||
6. **IndexAugmentation** - Reads metadata to build indexes
|
||||
7. **MonitoringAugmentation** - Reads metadata for monitoring
|
||||
8. **MetricsAugmentation** - Reads metadata for metrics collection
|
||||
9. **BatchProcessingAugmentation** - Reads metadata to check for external IDs
|
||||
10. **EntityRegistryAugmentation** - Reads metadata to register entities
|
||||
11. **AutoRegisterEntitiesAugmentation** - Reads metadata for auto-registration
|
||||
12. **ConduitAugmentation** - Reads metadata to pass through operations
|
||||
|
||||
### Category 3: Metadata Writers (needs specific access)
|
||||
These augmentations modify metadata and need specific field declarations:
|
||||
|
||||
13. **SynapseAugmentation** - Writes to '_synapse' field
|
||||
```typescript
|
||||
metadata: {
|
||||
reads: '*',
|
||||
writes: ['_synapse', '_synapseTimestamp'],
|
||||
namespace: '_synapse' // Uses its own namespace
|
||||
}
|
||||
```
|
||||
|
||||
14. **IntelligentVerbScoringAugmentation** - Adds scoring to verbs
|
||||
```typescript
|
||||
metadata: {
|
||||
reads: ['type', 'verb', 'source', 'target'],
|
||||
writes: ['weight', 'confidence', 'intelligentScoring']
|
||||
}
|
||||
```
|
||||
|
||||
15. **ServerSearchAugmentation** - Might add server metadata
|
||||
```typescript
|
||||
metadata: {
|
||||
reads: '*',
|
||||
writes: ['_server', '_syncedAt']
|
||||
}
|
||||
```
|
||||
|
||||
16. **NeuralImportAugmentation** - Enriches imported data
|
||||
```typescript
|
||||
metadata: {
|
||||
reads: '*',
|
||||
writes: ['nounType', 'verbType', '_importedAt', '_enriched']
|
||||
}
|
||||
```
|
||||
|
||||
### Category 4: API/Server (needs analysis)
|
||||
17. **ApiServerAugmentation** - Likely read-only for serving data
|
||||
18. **StorageAugmentations** (plural) - Collection of storage implementations
|
||||
19. **ConduitAugmentations** (plural) - Collection of conduit types
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### Phase 1: Update Base Interface
|
||||
1. Update `BrainyAugmentation` interface to require `metadata` field
|
||||
2. Update `BaseAugmentation` class to have abstract `metadata` property
|
||||
3. Add runtime enforcement in augmentation executor
|
||||
|
||||
### Phase 2: Update Each Augmentation
|
||||
For each augmentation, add the appropriate metadata declaration:
|
||||
|
||||
#### Example Updates:
|
||||
|
||||
**CacheAugmentation:**
|
||||
```typescript
|
||||
export class CacheAugmentation extends BaseAugmentation {
|
||||
readonly name = 'cache'
|
||||
readonly metadata = 'none' as const // ✅ No metadata access
|
||||
// ... rest unchanged
|
||||
}
|
||||
```
|
||||
|
||||
**WALAugmentation:**
|
||||
```typescript
|
||||
export class WALAugmentation extends BaseAugmentation {
|
||||
readonly name = 'WAL'
|
||||
readonly metadata = 'readonly' as const // ✅ Only reads for logging
|
||||
// ... rest unchanged
|
||||
}
|
||||
```
|
||||
|
||||
**SynapseAugmentation:**
|
||||
```typescript
|
||||
export abstract class SynapseAugmentation extends BaseAugmentation {
|
||||
readonly name = 'synapse'
|
||||
readonly metadata = {
|
||||
reads: '*',
|
||||
writes: ['_synapse', '_synapseTimestamp'],
|
||||
namespace: '_synapse'
|
||||
} as const
|
||||
// ... rest unchanged
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 3: Runtime Enforcement
|
||||
Add a metadata access enforcer that:
|
||||
1. Wraps metadata objects based on declared access
|
||||
2. Throws errors if augmentation violates its contract
|
||||
3. Logs warnings in development mode
|
||||
|
||||
```typescript
|
||||
class MetadataEnforcer {
|
||||
enforce(augmentation: BrainyAugmentation, metadata: any): any {
|
||||
if (augmentation.metadata === 'none') {
|
||||
return null // No access at all
|
||||
}
|
||||
|
||||
if (augmentation.metadata === 'readonly') {
|
||||
return Object.freeze(deepClone(metadata)) // Read-only copy
|
||||
}
|
||||
|
||||
// For specific access, create proxy that validates
|
||||
return new Proxy(metadata, {
|
||||
set(target, prop, value) {
|
||||
const access = augmentation.metadata as MetadataAccess
|
||||
if (!access.writes?.includes(String(prop)) && access.writes !== '*') {
|
||||
throw new Error(`Augmentation '${augmentation.name}' cannot write to field '${String(prop)}'`)
|
||||
}
|
||||
target[prop] = value
|
||||
return true
|
||||
}
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
1. **Type Safety** - TypeScript enforces metadata declaration
|
||||
2. **Runtime Safety** - Violations caught immediately
|
||||
3. **Documentation** - Contract shows exactly what each augmentation does
|
||||
4. **Brain-cloud Ready** - Registry can validate augmentations
|
||||
5. **Developer Friendly** - Most use simple 'none' or 'readonly'
|
||||
|
||||
