+## Architecture Overview
+
+### Memory-Driven Workflow Loop
+
+```
+Poimen Workflow (10 Phases)
+    ↓
+For Each Step:
+    ├─ 1. GetContextActivity (retrieve lessons)
+    ├─ 2. Optimize prompt (add learned facts + skills)
+    ├─ 3. Execute with agent
+    ├─ 4a. Success → LearnFromExecutionActivity
+    ├─ 4b. Failure → AnalyzeErrorActivity
+    ├─ 5. Always → DocumentDecisionActivity
+    └─ 6. Continue or retry (with memory guidance)
+
+Memory Service (PostgreSQL + OpenSearch + Vault)
+    ├─ L1 Knowledge: Task execution results
+    ├─ L2 Knowledge: Verified patterns & decisions
+    ├─ R (Reference): Docs, skill examples
+    └─ Vault: Organized by tool/phase/domain
+```
+
+### Skills & Context Flow
+
+```
+Workflow Execution
+    ↓
+Tools Used ─────────→ Skills Retrieved from Memory
+    ├─ WorkflowDefBuilder ──→ IR canonicalization rules
+    ├─ EventLog ────────────→ State machine patterns
+    ├─ RunExecutor ─────────→ Attempt lifecycle

+    ├─ ModelProvider ───────→ Prompt optimization
+    └─ Storage Ports ───────→ Retention policies
+    ↓
+Skills Guide Execution ─→ Results Learned
+                         ├─ Success patterns (L1)
+                         ├─ Failure recovery (L1)

+- Activity-context-aware error wrapping
+- Retryable vs non-retryable error classification
+- Timeout handling per activity type
+
+### Performance
+- Parallel context retrieval (async)

+- Non-blocking learn/document operations
+
+### Observability
+- Temporal activity logging with metadata
+- Per-activity attempt tracking

+
+## How to Deploy
+
+### 1. Register Activities in Worker
+
+```go
+// In cmd/worker/main.go
+import "github.com/rockliang/poimen/workflows/internal/memory"
+
+func main() {
+    c, _ := client.Dial(client.Options{
+        HostPort: "temporal-frontend.temporal:7233",
+        Namespace: "poimen-harness",
+    })
+    defer c.Close()
+
+    w := worker.New(c, "poimen-taskqueue", worker.Options{})
+
+    // Register memory activities
+    memSvc := memory.NewService(
+        os.Getenv("MEMORY_SERVICE_URL"),
+        os.Getenv("MEMORY_SERVICE_TOKEN"),
+        "poimen",
+    )
+    memory.RegisterMemoryActivities(w, memSvc)
+
+    w.Start()
+    defer w.Stop()
+}
+```
+
+### 2. Ingest Skills
+
+```bash
+# From YAML
+cat prompts/skills.yaml | memory-ingest --level L2
+
+# From Rust docs
+cargo doc --extract-comments | memory-ingest --level L2
+```
+
+### 3. Use in RunExecutor
+
+```go
+// In run_executor.rs (Rust)
+fn execute_step(...) {
+    // Pre-execution
+    let context = self.memory_svc
+        .retrieve_context("planner", "step-id", budget)
+        .await?;
+
+    // Optimize prompt
+    let prompt = optimize_with_context(base_prompt, context);
+
+    // Execute
+    let output = agent.execute(prompt);
+
+    // Post-execution
+    self.memory_svc
+        .learn_from_execution("step-id", output, tags)
+        .await
+        .ok();
+}
+```
+
+---
+
+## Testing
+
+Run all tests:
+```bash
+cd ~/workplace/Poimen/workflows
+go test ./internal/memory -v
+# Output: PASS: 23/23 tests (0.315s)
+```
+
+Run specific activity:
+```bash
+go test ./internal/memory -v -run TestActivityCreateKnowledge
+```
+
+---
+
+## Next Steps

+1. ✅ Activities defined & tested
+2. ✅ Full documentation complete
+3. ✅ Integration patterns documented
+4. 🔄 Deploy to cluster
