🎯 THE SYSTEM ARCHITECTURE
================================================================================

User Input (one-time or scheduled):
  "Analyze repo for security and quality"
  or
  "Scan all repos daily at 2 AM"

          ↓

[llm-router Activity] - Intelligent Workflow Generator
  ├─ Reads: ActivityKnowledgeBase.json (metadata about activities)
  ├─ Uses LLM to understand intent
  ├─ Selects activities: Clone → Analyze → SecurityScan → Combine → Notify
  ├─ Orders by dependencies
  ├─ Decides timeout for each (from knowledge base)
  ├─ Decides retry policy (from isFlaky flag)
  ├─ Chains parameters (JSONPath: ${Clone.output.path})
  ├─ Detects if scheduled (cron)
  └─ Generates: WorkflowSpec or CronWorkflowSpec (JSON)

          ↓

[RoutingWorkflow] - Generic Executor
  ├─ Takes JSON spec from llm-router
  ├─ Executes states in order
  ├─ Respects timeout/retry for each activity
  ├─ Handles errors with catch blocks
  └─ Returns results

          ↓

[Temporal] - Distributed Workflow Engine
  ├─ For one-time: Executes immediately
  ├─ For cron: Schedules and runs on schedule
  ├─ Provides durability (replay guarantee)
  ├─ Tracks execution history
  └─ Handles retries automatically

          ↓

[Results] - Final Output
  ├─ Execution history
  ├─ Step-by-step results
  ├─ Performance metrics
  └─ Status updates

================================================================================
✨ KEY FEATURES
================================================================================

✅ One-time workflows (instant execution via API/CLI)
✅ Scheduled workflows (cron jobs with full history)
✅ Intelligent routing (LLM decides what to run)
✅ Smart timeouts (from ActivityKnowledgeBase.json)
✅ Smart retries (3x for flaky, 1x for stable)
✅ Error handling (catch blocks for graceful failures)
✅ Parameter chaining (JSONPath: ${step.output.field})
✅ Parallel execution (multiple branches)
✅ Temporal durability (automatic replay on failure)
✅ HTTP API (for programmatic access)
✅ CLI (for command-line access)
✅ Execution tracking (full history)
✅ Backward compatible (legacy CLI still works)

================================================================================
🚀 HOW TO START TODAY
================================================================================

Step 1: Review Documentation (1-2 hours)
  → Read ROUTING_WORKFLOW_SPEC.md (understand design)
  → Read IMPLEMENTATION_TASKS.md (understand tasks)
  → Read README_IMPLEMENTATION.md (quick start)

Step 2: Assign Tasks (30 minutes)
  → Engineer 1: Tasks 1.1-1.4, 2.1-2.5, 3.1-3.6
  → Engineer 2: Tasks 4.1-4.4, 5.1-5.4, 6.1-6.4

Step 3: Begin Implementation (immediately)
  → Start with Task 1.1: Create Go types (types.go)
  → 2 hours to completion
  → Then proceed to Task 1.2 (ActivityKnowledgeBase.json)

Step 4: Daily Sync
  → Report progress
  → Unblock dependencies
  → Adjust timeline if needed

================================================================================
✅ SUCCESS CRITERIA
================================================================================

Phase 1: All types compile, KB loads, validator works
Phase 2: llm-router generates valid specs, detects cron
Phase 3: RoutingWorkflow executes any spec, handles errors
Phase 4: HTTP API + CLI fully functional
Phase 5: >90% code coverage, all tests pass
Phase 6: Complete documentation, ready to ship

✅ DONE WHEN:
  - All code compiles without warnings
  - All tests pass (unit, integration, E2E, load)
  - Documentation complete
  - Can deploy to Kubernetes
  - Can submit workflows from API/CLI
  - Can create cron jobs
  - Performance targets met (<200ms submit, <100ms poll)
