+# MS22 Agent Memory Module
+
+## Objective
+
+Add per-agent key/value store: AgentMemory model + NestJS module with CRUD endpoints.
+
+## Issues
+
+- MS22-DB-002: Add AgentMemory schema model
+- MS22-API-002: Add agent-memory NestJS module
+
+## Plan
+
+1. AgentMemory model → schema.prisma (after AgentSession, line 736)
+2. Add `agentMemories AgentMemory[]` relation to Workspace model
+3. Create apps/api/src/agent-memory/ with service, controller, DTOs, specs
+4. Register in app.module.ts
+5. Migrate: `prisma migrate dev --name ms22_agent_memory`
+6. lint + build
+7. Commit
+
+## Endpoints
+
+- PUT /api/agents/:agentId/memory/:key (upsert)
+- GET /api/agents/:agentId/memory (list all)
+- GET /api/agents/:agentId/memory/:key (get one)
+- DELETE /api/agents/:agentId/memory/:key (remove)
+
+## Auth
+
+- @UseGuards(AuthGuard, WorkspaceGuard, PermissionGuard)
+- @Workspace() decorator for workspaceId
+- Permission.WORKSPACE_MEMBER for write ops
+- Permission.WORKSPACE_ANY for read ops
+
+## Schema
+
+```prisma
+model AgentMemory {
+  id          String   @id @default(uuid()) @db.Uuid
+  workspaceId String   @map("workspace_id") @db.Uuid
+  agentId     String   @map("agent_id")
+  key         String
+  value       Json
+  createdAt   DateTime @default(now()) @map("created_at") @db.Timestamptz
+  updatedAt   DateTime @updatedAt @map("updated_at") @db.Timestamptz
+
+  workspace Workspace @relation(fields: [workspaceId], references: [id], onDelete: Cascade)
+
+  @@unique([workspaceId, agentId, key])

+# MS22 — Conversation Archive Module
+
+## Objective
+
+Implement ConversationArchive module: ingest OpenClaw session logs, store with vector embeddings for semantic search.
+
+## Deliverables
+
+1. ConversationArchive Prisma model
+2. NestJS module at apps/api/src/conversation-archive/
+3. Endpoints: ingest, search, list, get-by-id
+4. Register in app.module.ts
+5. Migrate, lint, build, commit
+
+## Plan
+
+- Add model to schema.prisma (end of file)
+- Add relation to Workspace model
+- Create module structure: dto/, service, controller, spec, module
+- Use EmbeddingService from knowledge module (import KnowledgeModule or just PrismaModule + embed inline)
+- Follow pattern: AuthGuard + WorkspaceGuard + PermissionGuard
+- Endpoint prefix: conversations (maps to /api/conversations)
+- Vector search: $queryRaw with <=> operator (cosine distance)
+
+## Assumptions
+
+- ASSUMPTION: Embedding is stored inline on ConversationArchive (not a separate table) — simpler and sufficient for this use case, matches MemoryEmbedding pattern
+- ASSUMPTION: Import KnowledgeModule to reuse EmbeddingService (it exports it)
+- ASSUMPTION: messageCount computed server-side from messages array length on ingest
+- ASSUMPTION: Permission level WORKSPACE_MEMBER for ingest/search, WORKSPACE_ANY for list/get
+
+## Progress
+
+- [ ] Schema model
+- [ ] Migration
+- [ ] DTOs
+- [ ] Service
+- [ ] Controller
+- [ ] Spec
+- [ ] Module
+- [ ] app.module.ts registration
+- [ ] Lint + build
+- [ ] Commit
+
+## Risks
+
+- EmbeddingService exports from knowledge.module — need to import KnowledgeModule
+- Migration requires live DB (may need --skip-generate flag if no DB access)
