From 1f6fe1d30bfbec333507a87cf8ab53a8389e5093 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Wed, 27 Aug 2025 15:38:48 -0700 Subject: [PATCH] feat: comprehensive metadata namespace architecture and cleanup system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: Remove hard delete option from deleteVerb() for consistent API - Add complete metadata namespace architecture with O(1) soft delete performance - Implement periodic cleanup system for old soft-deleted items - Add restore methods for both nouns and verbs - Require metadata contracts for all augmentations - Eliminate namespace collisions with clean separation (_brainy, _augmentations, _audit) - Optimize index performance using flattened dot-notation for O(1) lookups - Add comprehensive augmentation safety system with type-safe access control - Maintain full backward compatibility for existing data - Add enterprise-grade cleanup with configurable age thresholds and batch processing πŸ€– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- AUGMENTATION_SAFETY.md | 299 +++++++++++++ METADATA_ARCHITECTURE.md | 220

+## 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. πŸ”΄ 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 + +### βœ… Good: Category Enricher +```typescript +class CategoryEnricher { + contract = { + writes: { + userFields: [{ + field: 'category', + type: 'create', + description: 'Auto-categorization' + }] + } + } + + execute(metadata) { + metadata.category = 'technology' // βœ… Allowed + metadata.random = 'value' // ❌ Throws error + } +} +``` + +### βœ… Good: Translation Service +```typescript +class Translator { + contract = { + writes: { + userFields: [{ + field: 'translations', + type: 'merge' + }] + } + } + + execute(metadata) { + metadata.translations = { // βœ… 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 =

'translations.es', + oldValue: undefined, + newValue: 'TecnologΓ­a', + timestamp: 1704067201000 + } +] +``` + +## Implementation Guide + +### Step 1: Define Your Contract +```typescript +export const

+ } + + 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 βœ… +- 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 + +##
