Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Build a Go Connect-RPC API server + React/TypeScript dashboard with Connect-ES that reads from Omega's SQLite state store and renders live visibility into the self-improving agent system.\n\n**Architecture:** Proto definitions are the contract. Go server (`cmd/omega-api`) reads from the shared SQLite DBs that the Python node layer writes to. React dashboard uses `@connectrpc/connect-web` to call the Go server directly — no REST, no WebSockets. Real-time updates use server-streaming RPC (`StreamEvents`).\n\n**Tech Stack:** Go 1.24+, `connectrpc.com/connect`, `modernc.org/sqlite`, `google.golang.org/protobuf`, Buf CLI; Vite 5, React 18, TypeScript, `@connectrpc/connect-web` v2, `@bufbuild/protobuf`, Tailwind CSS, shadcn/ui, recharts\n\n---\n\n## Key Data Facts (from existing Python codebase)\n\n- **State store DB**: `/tmp/omega_victoria_state.db`\n  - Tables: `nodes`, `node_executions`, `traces`, `cost_events`, `issues`, `activity_log`, `improvement_log`, `config_revisions`\n- **Memory DB**: `/tmp/omega_victoria_memory.db`\n  - Tables: `episodes`, `semantic_memories`, `memory_ratings`\n- **Convergence data**: `episodes WHERE event_type='cycle_summary'` contains `score`, `pipeline_ms` per cycle\n- **Node namespacing**: memory is namespaced by node name (e.g., `\"DataIngestionNode\"`)\n- **Toolchain available**: Go 1.26, Buf 1.47, Node 22, npm 10\n\n---\n\n## File Map\n\n### Proto

Write them using the generated proto types from `./gen/omega/v1/types_pb`.\n\n**`Nodes.tsx` detail panel pattern:**\n```tsx\n// When a node is selected, show node stats + brain config side by side\n{selectedNode && (\n  <div className=\"grid grid-cols-1 lg:grid-cols-2 gap-4 mt-4\">\n    <div className=\"space-y-4\">\n      {/* node stats, latency chart, execution history */}\n    </div>\n    <BrainConfigPanel nodeId={selectedNode.nodeId} />\n  </div>\n)}\n```\n\n- [ ] **Step 2: Verify build**\n\n```bash\ncd /Users/benebsworth/projects/omega/dashboard\nnpm run build 2>&1 | tail -10\n```\n\nExpected: `built in Xs` with no errors.\n\n- [ ] **Step 3: Commit**\n\n```bash\ngit add dashboard/src/pages/\ngit commit -m \"feat(dashboard): complete all 7 pages\"\n```\n\n---\n\n## Task 11: End-to-End Verification\n\n- [ ] **Step 1: Run one Python heartbeat to populate SQLite DBs**\n\n```bash\ncd /Users/benebsworth/projects/omega\npython -m omega.examples.victoria_main --once\n```\n\nExpected: heartbeat runs, data written to `/tmp/omega_victoria_state.db`.\n\n- [ ] **Step 2: Start Go API server**\n\n```bash\ncd /Users/benebsworth/projects/omega\n./omega-api &\nsleep 1\n```\n\n- [ ] **Step 3: Verify key endpoints**\n\n```bash\n# Health\ncurl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/GetHealth \\\n  -H \"Content-Type: application/json\" -d '{}' | python3 -m json.tool\n\n# Nodes\ncurl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/ListNodes \\\n  -H \"Content-Type: application/json\" -d '{}' | python3 -m json.tool | head -30\n\n# Traces\ncurl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/ListTraces \\\n  -H \"Content-Type: application/json\" -d '{\"limit\": 5}' | python3 -m json.tool\n\n# Brain config — list providers\ncurl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/ListAvailableProviders \\\n  -H \"Content-Type: application/json\" -d '{}' | python3 -m json.tool\n\n# Brain config — get node config (replace NODE_ID with a real node_id from ListNodes)\nNODE_ID=$(curl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/ListNodes \\\n  -H \"Content-Type: application/json\" -d '{}' | python3 -c \"import sys,json; d=json.load(sys.stdin); print(d['nodes'][0]['nodeId'])\" 2>/dev/null)\ncurl -s -X POST http://localhost:8080/omega.v1.OrchestratorService/GetNodeConfig \\\n  -H \"Content-Type: application/json\" -d \"{\\\"nodeId\\\": \\\"$NODE_ID\\\"}\" | python3 -m json.tool\n```\n\nExpected: nodes with health scores, at least one trace, providers list with 5 entries, node config defaulting to `claude-sonnet-4-6`.\n\n- [ ] **Step 4: Start frontend**\n\n```bash\ncd /Users/benebsworth/projects/omega/dashboard\nnpm run dev &\nsleep 2\necho \"Dashboard at http://localhost:5173\"\n```\n\n- [ ] **Step 5: Verify via Playwright MCP**\n\nUse `mcp__plugin_playwright_playwright__browser_navigate` to visit `http://localhost:5173` and take a screenshot to confirm the dashboard loads.\n\n- [ ] **Step 6: Final commit**\n\n```bash\ncd /Users/benebsworth/projects/omega\ngit add -A\ngit commit -m \"feat: complete Omega Go+Connect-RPC API and React dashboard\"\n```\n\n---\n\n## Quick-start (reference)\n\n```bash\n# Terminal 1: Go API\ncd /Users/benebsworth/projects/omega\ngo build ./cmd/omega-api && ./omega-api\n\n# Terminal 2: React dashboard\ncd /Users/benebsworth/projects/omega/dashboard\nnpm run dev\n\n# Terminal 3: Python orchestrator\npython -m omega.examples.victoria_main --heartbeat 60\n\n# Open dashboard\nopen http://localhost:5173\n```\n"}, "6aacba45811078ea307cc43f195afd1820abcfc5": {"t": 1785764522.6597192, "n": 100004, "h": "0bdffc42d150ad01", "c": "# Omega Web Dashboard — Go + Connect-RPC + Protobuf Implementation Plan\n\n> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Build a Go Connect-RPC API server + React/TypeScript dashboard with Connect-ES that reads from Omega's SQLite state store and renders live visibility into the self-improving agent system.\n\n**Architecture:** Proto definitions are the contract. Go server (`cmd/omega-api`) reads from the shared SQLite DBs that the Python node layer writes to. React dashboard uses `@connectrpc/connect-web` to call the Go server directly — no REST, no WebSockets. Real-time updates use server-streaming RPC (`StreamEvents`).\n\n**Tech Stack:** Go 1.24+, `connectrpc.com/connect`, `modernc.org/sqlite`, `google.golang.org/protobuf`, Buf CLI; Vite 5, React 18, TypeScript, `@connectrpc/connect-web` v2, `@bufbuild/protobuf`, Tailwind CSS, shadcn/ui, recharts\n\n---\n\n## Key Data Facts (from existing Python codebase)\n\n- **State store DB**: `/tmp/omega_victoria_state.db`\n  - Tables: `nodes`, `node_executions`, `traces`, `cost_events`, `issues`, `activity_log`, `improvement_log`, `config_revisions`\n- **Memory DB**: `/tmp/omega_victoria_memory.db`\n  - Tables: `episodes`, `semantic_memories`, `memory_ratings`\n- **Convergence data**: `episodes WHERE event_type='cycle_summary'` contains `score`, `pipeline_ms` per cycle\n- **Node namespacing**: memory is namespaced by node name (e.g., `\"DataIngestionNode\"`)\n- **Toolchain available**: Go 1.26, Buf 1.47, Node 22, npm 10\n\n---\n\n## File Map\n\n### Proto

Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Build a Go Connect-RPC API server + React/TypeScript dashboard with Connect-ES that reads from Omega's SQLite state store and renders live visibility into the self-improving agent system.\n\n**Architecture:** Proto definitions are the contract. Go server (`cmd/omega-api`) reads from the shared SQLite DBs that the Python node layer writes to. React dashboard uses `@connectrpc/connect-web` to call the Go server directly — no REST, no WebSockets. Real-time updates use server-streaming RPC (`StreamEvents`).\n\n**Tech Stack:** Go 1.24+, `connectrpc.com/connect`, `modernc.org/sqlite`, `google.golang.org/protobuf`, Buf CLI; Vite 5, React 18, TypeScript, `@connectrpc/connect-web` v2, `@bufbuild/protobuf`, Tailwind CSS, shadcn/ui, recharts\n\n---\n\n## Key Data Facts (from existing Python codebase)\n\n- **State store DB**: `/tmp/omega_vectora_state.db`\n  - Tables: `nodes`, `node_executions`, `traces`, `cost_events`, `issues`, `activity_log`, `improvement_log`, `config_revisions`\n- **Memory DB**: `/tmp/omega_vectora_memory.db`\n  - Tables: `episodes`, `semantic_memories`, `memory_ratings`\n- **Convergence data**: `episodes WHERE event_type='cycle_summary'` contains `score`, `pipeline_ms` per cycle\n- **Node namespacing**: memory is namespaced by node name (e.g., `\"DataIngestionNode\"`)\n- **Toolchain available**: Go 1.26, Buf 1.47, Node 22, npm 10\n\n---\n\n## File Map\n\n### Proto

Steps use checkbox (`- [ ]`) syntax for tracking.\n\n**Goal:** Build a Go Connect-RPC API server + React/TypeScript dashboard with Connect-ES that reads from Omega's SQLite state store and renders live visibility into the self-improving agent system.\n\n**Architecture:** Proto definitions are the contract. Go server (`cmd/omega-api`) reads from the shared SQLite DBs that the Python node layer writes to. React dashboard uses `@connectrpc/connect-web` to call the Go server directly — no REST, no WebSockets. Real-time updates use server-streaming RPC (`StreamEvents`).\n\n**Tech Stack:** Go 1.24+, `connectrpc.com/connect`, `modernc.org/sqlite`, `google.golang.org/protobuf`, Buf CLI; Vite 5, React 18, TypeScript, `@connectrpc/connect-web` v2, `@bufbuild/protobuf`, Tailwind CSS, shadcn/ui, recharts\n\n---\n\n## Key Data Facts (from existing Python codebase)\n\n- **State store DB**: `/tmp/omega_victoria_state.db`\n  - Tables: `nodes`, `node_executions`, `traces`, `cost_events`, `issues`, `activity_log`, `improvement_log`, `config_revisions`\n- **Memory DB**: `/tmp/omega_victoria_memory.db`\n  - Tables: `episodes`, `semantic_memories`, `memory_ratings`\n- **Convergence data**: `episodes WHERE event_type='cycle_summary'` contains `score`, `pipeline_ms` per cycle\n- **Node namespacing**: memory is namespaced by node name (e.g., `\"DataIngestionNode\"`)\n- **Toolchain available**: Go 1.26, Buf 1.47, Node 22, npm 10\n\n---\n\n## File Map\n\n### Proto
