Snapshot Pattern for Versioned Data + +**Learning**: Store metadata alongside data for robust versioning. + +**Structure**: +```typescript +interface StoredSnapshot { + kind: SnapshotKind; // What state + capturedAt: string; // When (versioning key) + sourceService: string; // Who + sourceTopic: string; // Where from + sequence: number | undefined; // Order hint + updatedAt: string; // When stored + event: InternalEventV2; // The data +} +``` + +**Benefits**: +- Versioning without external coordination +- Audit trail (who/when/where) +- Debugging visibility +- Evolution support + +**Applicability**: Cached data, temporary storage, event sourcing. + +--- + +## Architecture Learnings + +### 13. Single Snapshot Topic for All Kinds + +**Learning**: Use one topic (`internal.persistence.snapshot.v1`) with `kind` field instead of separate topics per kind. + +**Why**: +- Simpler routing (one subscription) +- Easier versioning (all kinds in same namespace) +- Consistent handling (one handler) +- Future kinds supported (no topic changes) + +**Trade-off**: +- Handler must switch on `kind` field +- Can't filter at subscription level + +**Decision**: Simplicity wins for low-volume snapshots. + +**Applicability**: Event taxonomies with similar handling. + +--- + +## Conclusion + +Sprint 24 provided valuable learnings across technical, process, and architectural domains.

Store ALL Snapshot Kinds (Not Just 'final') + +**Decision**: Claim-check stores all snapshot kinds ('initial', 'update', 'final', 'deadletter') + +**Rationale**: +- Early snapshots useful for progress tracking +- Versioning ensures latest snapshot stored +- No significant memory overhead (TTL cleanup) +- Flexibility for future use cases + +**Outcome**: ✅ Enables richer debugging and progress messages + +### 3. Platform-Only MCP Tools + +**Decision**: Claim-check MCP tools exposed only to platform (not domain LLMs) + +**Rationale**: +- Security: Events may contain sensitive data +- Performance: Prevents runaway token usage +- Architecture: Domain services shouldn't need raw event access + +**Outcome**: ✅ Aligns with security model, prevents misuse + +### 4.

The Claim Check pattern enables Bits to offload content to Redis-backed temporary storage and reference it by ID, solving two critical use cases: cross-bit event access and multi-modal content handling. + +**Current State**: Bits have no mechanism to access events outside their routing slip scope. The tool-gateway cannot access the source event when tools are invoked (needed for progress messages). Multi-modal content (images, videos, files) has no standard storage pattern. + +**Target State**: A dedicated claim-check Bit providing: +1.

Problem Statement + +### 1.1 Cross-Bit Event Access Problem + +**Use Case**: Tool-gateway needs access to the source event when an agent invokes a tool. + +**Example** (Progress Message Tool - Sprint 22): +```typescript +// In llm-bot service +const toolResult = await this.mcpClient.callTool('agent.sendProgressUpdate', { + message: 'Analyzing your code...' +}); + +// Problem: tool-gateway receives tool call but has NO ACCESS to: +// - Original user request +// - Event ingress metadata (platform, channel, user ID) +// - Event egress configuration (how to deliver the progress message) +// - Routing context (correlationId, routing slip) +``` + +**Current Workaround**: None. Tool-gateway cannot implement features requiring source event context. + +**Impact**: +- Progress messages cannot be sent from tools (Sprint 22 blocker) +- Tools cannot access user identity/permissions from parent event +- Tools cannot trace back to original request for logging/debugging +- Cross-Bit coordination is difficult without shared event context + +### 1.2 Multi-Modal Content Problem + +**Use Case**: Integration Bits receive multi-modal content (images, videos, files) that must flow through the agent orchestration pipeline. + +**Example** (Discord image upload): +```typescript +// Discord bot receives message with image attachment +const event: InternalEventV2 = { + v: '2', + type: 'internal.ingress.v1', + message: { role: 'user', text: 'What is in this image?' }, + payload: { + // PROBLEM: Where does the image data go? + attachments: [{ url: 'https://cdn.discord.com/...', size: '2.5MB', type: 'image/png' }] + }, + // Event flows through: router → auth → llm-bot → egress + // Image URL may expire before llm-bot processes it + // Event payload becomes bloated if we embed the binary data +}; +``` + +**Current State**: No standard pattern for multi-modal content. + +**Impact**: +- Events become bloated with binary data +- CDN URLs expire before processing completes +- No separation of concerns (content vs metadata) +- Difficult to implement image analysis, transcription, etc. + +### 1.3 The Gap + +**We need**: +1. **Temporary event storage**: Store successfully persisted events by correlationId for cross-Bit access +2. **Blob storage**: Store large content separate from events with aggressive TTL +3. **Simple API**: MCP tools for store/retrieve operations +4. **Bit integration**: Easy access pattern from any Bit + +--- + +## 2. Current State Analysis + +### 2.1 Existing Storage Infrastructure + +#### A. Redis Infrastructure (Sprint 1) + +**Current Use**: Distributed idempotency tracking + +**Location**: `src/common/resources/redis-manager.ts` + +**Pattern**: +```typescript +// Singleton Redis connection manager +const redis = await RedisManager.setup(context); + +// Atomic operations +await redis.set(key, 'processed', { NX: true, EX: ttlSeconds }); +``` + +**Capabilities**: +- Singleton connection with auto-reconnect +- Health checks and graceful shutdown +- Fail-open resilience strategy +- Environment-driven configuration (`REDIS_URL`) +- Already deployed in all environments + +**Architecture** (from architecture.yaml:235-270): +```yaml +caching: + service: redis + image: redis:7-alpine + command: + - redis-server + - '--maxmemory' + - 512mb + - '--maxmemory-policy' + - allkeys-lru + - '--appendonly' + - 'yes' +``` + +**Assessment**: ✅ Redis is production-ready and suitable for claim check storage. + +#### B. Persistence Snapshot System + +**Topic**: `internal.persistence.snapshot.v1` + +**Purpose**: Audit logging of successfully persisted events + +**Location**: `src/common/events/persistence-snapshots.ts` + +**Publishers** (from architecture.yaml): +- `ingress-egress` (line 598) +- `api-gateway` (line 756) +- `scheduler` (line 829) + +**Consumer**: +- `persistence` service (line 76 of persistence-service.ts) + +**Event Schema**: +```typescript +interface PersistenceSnapshotEventV1 { + v: '1'; + correlationId: string; + kind: 'initial' | 'intermediate' | 'final' | 'deadletter'; + capturedAt: string; + sourceService: string; + sourceTopic: string; + idempotencyKey: string; + stage?: RoutingStage; + stepId?: string; + attempt?: number; + changeSummary?: string; + delivery?: SnapshotDeliveryV1; + deadletter?: SnapshotDeadletterV1; + event: InternalEventV2; // Full event snapshot +} +``` + +**Assessment**: ✅ Persistence snapshots provide the exact event data we need. The claim-check Bit can subscribe to `internal.persistence.snapshot.v1` and store events in Redis. + +#### C. MCP Infrastructure + +**Bit Model** (Sprint 324): +- Every Bit exposes MCP control plane +- `registerTool()` for tool registration +- `McpClientProfile` mixin for tool consumption +- Tool discovery via `internal.mcp.registration.v1` + +**Tool Gateway**: +- Proxies MCP tools from all Bits +- Enforces RBAC +- Routes tool calls to appropriate Bit + +**Assessment**: ✅ MCP infrastructure is mature. Claim check tools follow established patterns. + +### 2.2 Related Patterns + +#### A. RedisManager Resource Pattern + +**File**: `src/common/resources/redis-manager.ts:18-90` + +**Pattern**: +```typescript +export class RedisManager implements ResourceManager { + async setup(context: SetupContext): Promise { + // Singleton memoization + if (memoizedClient) return memoizedClient; + + // Create client with retry strategy + const client = createClient({ + url: redisUrl, + socket: { reconnectStrategy: (retries) => Math.min(500 * Math.pow(1.5, retries), 3000) } + }); + + // Validate connection + await client.connect(); + const pong = await client.ping(); + if (pong !== 'PONG') throw new Error('Redis PING failed'); + + memoizedClient = client; + return client; + } +} +``` + +**Assessment**: ✅ Claim check Bit will reuse existing RedisManager pattern. + +#### B. Idempotency Key Format + +**File**: `src/common/idempotency-middleware.ts:89-113` + +**Pattern**: +```typescript +function generateIdempotencyKey(config: IdempotencyConfig): string { + const normalizedTopic = normalizeTopic(config.topic); + const parts = ['bitbrat', 'idempotency', normalizedTopic, config.correlationId]; + if (config.source) parts.push(config.source); + return parts.join(':'); +} + +// Example: bitbrat:idempotency:internal:egress:v1:abc123:ingress-egress +``` + +**Assessment**: ✅ Claim check will follow similar key naming: `bitbrat:claim:{type}:{id}` + +### 2.3 Gap Analysis + +| Capability | Current State | Required | Gap | +|------------|---------------|----------|-----| +| Redis connection | ✅ RedisManager exists | Redis storage | None | +| Event snapshots | ✅ Published to topic | Consume snapshots | New subscriber | +| Event storage | ❌ Not implemented | Store by correlationId | New functionality | +| Blob storage | ❌ Not implemented | Store binary/large data | New functionality | +| Retrieval API | ❌ Not implemented | MCP tools | New tools | +| TTL management | ✅ Redis supports | Aggressive expiry | Configuration | +| Base Bit integration | ❌ Not implemented | Easy access pattern | New helper methods | + +**Conclusion**: Infrastructure exists.
